From the perspective of safety and application conditions, this The document does not apply to marinas, shipyards and oil, gas and chemical terminals, or to the limits of human-operated systems specified in IEC 61439. Certainly. As it is clear in the preface that GB/T 38329 is divided into three parts, Part 1 is the high-voltage shore power connection (HVSC) system general requirements, delete the description of the relevant requirements for high-voltage shore power connection systems in the scope, see GB/T 38329.1 (see Section 1 chapter). ---For ease of understanding, the terms and definitions of "IT power system" and "connector" have been added (see 3.12 and 3.13). ---Because it is clear that this document does not apply to oil, gas and chemical terminals, the content of the compatibility assessment regarding the consideration of hazardous areas has been deleted [see IEC PAS80005-3.4.3m) in.2014], deleted the requirements for electrical equipment in hazardous areas (see IEC PAS80005-3. 4.6.4 in.2014), the emergency shutdown requirement for ship connection equipment that may move to hazardous areas has been deleted (see IEC PAS 80005-3.4.9 in.2014). ---In order to ensure the effective application of communications in shore power connection operations, compatibility assessment requirements for communications compatibility assessment are added [see 4.3p)]. ---Delete from the system design requirements "System integration of shore and ship LVSC systems shall be managed by a single designated party and shall be based on "Conducted in accordance with procedures that clarify the roles, responsibilities and requirements of relevant parties", this article does not apply to our country (see IEC PAS80005-3. 4.4.1 in.2014). ---In order to ensure good communication channels during shore power connection operations, it is added that "there should be independent communication between ships and dock shore power facility operators" "Establish a voice communication channel (such as a walkie-talkie)" (see 4.4.2.3). In order to ensure the standardization of system operation and clarify the responsibilities of relevant parties Responsibilities, adding "The operation of low-voltage shore power systems on shore and ships should comply with prescribed procedures, and determine the duties and responsibilities of all relevant parties. and requirements” (see 4.4.2.4). ---Modified the statement of connector rating requirements to maintain coordination with the description of relevant requirements in GB/T 11918.5 (see 4.7.6). ---Because my country's terminals currently provide ships with low-voltage power supply with ungrounded neutral points, the compatibility evaluation of the power distribution system before connection has been deleted. The content of the evaluation on the neutral point grounding evaluation of the shore transformer [see 4.3i) in IEC PAS80005-3.2014] has been deleted. Systematic research and calculation on shore power transformer neutral point grounding resistance analysis related content [see IEC PAS80005-3.2014 4.8c) and e)], delete the requirement that the secondary side transformer should be in star configuration with neutral point bushing (see IEC PAS80005-3. 6.2.2 in.2014), the requirement for neutral point grounding resistance is deleted (see 6.2.3 in IEC PAS80005-3.2014), and the ship The conditions for not requiring a shipboard transformer are determined by "the power grid on the ship is designed according to the shore power supply voltage and the neutral point processing is tied to the ship." "Unified and consistent" is adjusted to "The power system on board is consistent with the design voltage of shore power access" (see 8.5.2). Delete the special information in the appendix. Additional requirements for ship neutral point grounding resistors (see C.6.2.3 and D.6.2.3 in IEC PAS80005-3.2014) are specified to suit In response to my country's technical conditions. ---In the system research and calculation, the short-circuit current calculation adds the short-circuit current calculation "should be in accordance with GB/T 15544.2 and GB/T 15544.3 stipulates the requirements for "carrying out" and maintains coordination with relevant standards (see 4.8.1). The calculation of system charging current has been deleted and requirements related to transient overvoltage protection analysis [see 4.8d) and f) in IEC PAS80005-3.2014]. ---The rated voltage of the safety circuit relay is further clarified as "DC rated voltage U0 is 150V, AC rated voltage U is 250V (the maximum AC voltage Um is 300V)" (see 4.9.3). ---Deleted the AC690V nominal voltage (see 5.1 in IEC PAS80005-3.2014), and other nominal voltages in this document It is the relevant content of AC690V to adapt to the technical conditions of our country. ---Modify the conditions for using IEC other nominal voltages other than the nominal voltage specified in this document to adapt to my country's technical conditions (See 5.1.1). ---Deleted the requirement for galvanic isolation of low-voltage shore power connections and shore power distribution systems (see 5.1 in IEC PAS80005-3.2014). The requirements are duplicated with those related to 6.1. --- Added content requirements for power supply quality specifications to standardize power supply quality specifications (see 5.2.1). ---Adjust the steady-state voltage rise deviation value of the shore power connection point under no-load conditions from 6% to 5%, in compliance with the requirements of JTS155 Adjust to suit national technical conditions (see 5.2.2). ---It is added that shore connection devices should comply with the provisions of JTS155 to meet the requirements of my country's relevant mandatory standards (see 6.1.1.1). ---To ensure the compatibility of ship-to-shore systems, it is added that "ships equipped with IT (ungrounded) power systems should be connected to equivalent IT (ungrounded) Grounding) shore power system" requirements (see 6.1.1.4). ---To ensure safety, it is added that in the case of ground fault, the low-voltage circuit breaker on the secondary side of the shore-side transformer should disconnect all insulated electrodes. Seek (see 6.3.1). Since overvoltage protection and undervoltage protection have been stipulated for voltage protection, no other protection devices are needed, so the 6.3.1 The installation voltage transmission requirements proposed by the requirement for the secondary side low-voltage circuit breaker of the shore-side transformer to disconnect all insulated electrodes under the conditions listed in 6.3.1. Requirements for sensing devices (see 6.3 in IEC PAS80005-3.2014). To ensure grounding adopts ground fault of IT power system To realize the protection function, the requirement of "when shore power is connected, the ship's insulation monitoring equipment should be disconnected if necessary" (see 6.3.1). ---Deleted "Equipment grounding conductors that may require termination of shore power outlet box sockets to achieve equipotential bonding between shore and ship" Description of the possibility of connection to the ship's switchgear earth bus and/or to the hull" (see IEC PAS80005-3.2014 6.2.4). ---In order to meet safety requirements, the requirement that the circuit breaker should not close when "voltage exists in the downstream direction" is added (see 6.4.2). ---In order to avoid over-stretching or bending of the cables due to different lengths of the connecting cables, additional cables are added for each connection between the shore and the ship. The cables should have the same length requirements. At the same time, cutting off the power supply of a cable alone can easily cause a fault, which increases the number of times a fault occurs. The safety circuit is to be required to simultaneously cut off the power supply of all ship-to-shore connections (see 7.1.2). ---It is further clarified that only one factory-assembled mobile cable management system is allowed at each connection point of the ship-to-shore connection cable (see 7.1.7). ---For ease of understanding, a schematic diagram of the connection configuration between the ship and the mobile cable management system and the shore-based fixed cable management system has been added. Connection configuration diagram (see 7.2.1.3 and 7.2.1.4). ---Deleted the description of the recommended content that equivalent alternative measures may be considered for cable length monitoring (see IEC PAS80005-3.2014 7.2.3). ---Deleted the requirements for current unbalance protection of connecting conductors and duplicated the content of 6.3 (see 7.2.4 in IEC PAS80005-3.2014). ---Change the title of 7.3 from "Plugs and Sockets" to "Plugs, Sockets and Marine Couplers" to better match the technical content of this article (see 7.3). ---Added that the design of plugs, sockets, marine connectors and marine input sockets should comply with the provisions of GB/T 11918.5 to adapt my country's technical conditions (see 7.3.1.5). Removed information regarding the placement of plugs, receptacles, marine connectors, and marine input receptacles The requirements are repeated with the relevant content in the previous article (see 7.3.1 in IEC PAS80005-3.2014). Added plugs, sockets, marine inputs Type requirements for sockets and marine connectors, as well as quantity requirements for ship-to-shore configuration cables, to ensure coordination of connections and interfaces (see 7.3.1.3 and 7.3.1.4). ---For ease of understanding, the single-circuit power supply safety loop diagram has been deleted (see 7.3.1 in IEC PAS80005-3.2014) and optimized Dual-circuit power supply safety circuit diagram (see 7.3.1.11). Added the ability to detect when a plug is disconnected or a power cord is disconnected during shore power connection. In the event of an electrical fault in the cable, all shore and ship safety circuits shall be disconnected to meet safety requirements (see 7.3.1.15 and 7.3.1.16). ---When the shore power is connected, the current flowing through the ground contact is less than the phase line current. Delete "the current carrying capacity of the ground contact should be at least equal to that of other mains". "Contact rated current" requirements (see 7.3.3 in IEC PAS80005-3.2014). ---Deleted the requirement that "if control and monitoring cables are integrated with power cables, they should be able to withstand internal and external short-circuit currents". It is not accurate, and the insulation level of the cable has relevant standard requirements (see 7.5 in IEC PAS80005-3.2014). ---Deleted "When it is possible to be connected to more than one low voltage shore power supply, if there is any power supply exceeding the low voltage shore power or ship power system In the case of the maximum expected short-circuit current of the system/equipment, measures should be taken to prevent parallel connection of low-voltage shore power supplies." my country should With shore power, there is no way for a ship to be connected to multiple shore power sources at the same time (see IEC PAS80005-3.2014 8.2.1). ---Deleted the requirements related to changing equipment settings in 8.2.2, which do not belong to the requirements related to ground fault protection, monitoring and alarm (see 8.2.2 in IEC PAS80005-3.2014). ---Added that the rated closing capacity of the circuit breaker should not be less than the short-circuit current predetermined calculated in GB/T 15544.2 and GB/T 15544.3 The requirements for period peak value (IP) (see 8.3.2.3), and the rated short-circuit breaking capacity shall not be less than that in accordance with GB/T 15544.2 and The requirements for the maximum expected symmetrical short-circuit current [IAC (0.5T)] calculated in GB/T 15544.3 are coordinated with relevant standards (see 8.3.2.4). ---Deleted the requirement that the switchgear connected to shore power on board should have unbalance protection for systems with multiple cables, and also for single cables. There is unbalance protection (see 8.3.3 in IEC PAS80005-3.2014). For shipboard sockets, plugs, connectors and input jacks The protection of the base is added, "If the contact resistance increases abnormally, negative phase sequence overcurrent or internal thermal sensor or equivalent device can be provided. "Low-voltage marine equipment should include appropriate rated surge arresters" is added to ensure the safety of marine equipment. electrical appliances to protect against fast transient overvoltage surges (such as those caused by lightning strikes or switching surges)" requirements (see 8.3.3.2 and 8.3.3.5). ---Deleted "For ships that regularly conduct sailing trade, the operator may be responsible for both the ship and the shore low-voltage shore power connection system."
