This standard replaces GB/T 14810-1993 "110kV and above AC high voltage load switch."
This standard compared with GB/T 14810-1993, the main difference is.
--- Scope. Rated voltage generated by the "110kV and above" to "72.5kV and above," and added to determine the transmission system in use
Private and special-purpose load switch requirements.
--- Increases the switching means, terminology and definitions load switch components, operations, and other aspects of the characteristic parameters.
--- In the "design and structure" of the increased reliance power operation, the storage operation, do not rely on human power or operation, nameplates, Interlock installed
Home, housing protection class outdoor insulators creepage distance, fire (flammability), electromagnetic compatibility (EMC), X-ray hair
Shot, corrosion.
--- Increasing the protection level verification, X-ray test additional testing electromagnetic compatibility test, auxiliary and control circuits, vacuum interrupter
Inspection procedures and capacitor bank current switching test (in accordance with the provisions of GB 1984. introduction of the C1 and C2 grade level).
--- Increasing the cable or line charging current of the earth fault current and ground fault conditions (test mode 7a and 7b) and related
Test circuit.
--- Add special purpose load switch in frequent operation, the mechanical life test (M1 grade, M2 grade).
--- Increasing the mechanical operation test load state of the switch and after the test.
--- For the breaking test, frequency test voltage shall be maintained at least at the rear open time from 0.1s up to 0.3s.
--- Improved test mode load switch 3, 4a and 4b test mode and test mode 5b like operating cycles.
--- Added "guide for the selection of the load switch" "Query, the information provided by the tender and order," "transportation, storage, installation, operation and maintenance
Protection rules "," security "," impact on the environment "and so on.
This standard uses redrafted law revision using IEC 62271-104.2009 "Part 104 high-voltage switchgear and control equipment. the amount
Constant voltage 52kV and above AC load switch. "
This standard and IEC 62271-104. compared to 2009, the main difference is.
--- Scope. According to the actual situation of China's power grid, removing the IEC 62271-104. in 2009 related to the nominal frequency of 60Hz
Content; according to the division of the habit of pressure applied by the rated voltage "52kV and above" to "72.5kV and above."
--- Rated voltage. Removed and the rated voltage value independent of the power grid, according to GB/T 11022-2011 (or GB/T 156)
Listed voltage given; and based on actual operating experience and development status of the grid given rated voltage 1100kV
Relevant parameters.
--- Normative documents according to the actual situation of our country has been adjusted.
--- According to GB 1985 increased the level load switch M0, M1 class load switch, requirements and test methods M2 level load switch.
--- According to China's power grid voltage level standards, according to the formula provided in IEC 62271-104 for TRV standard parameters involved
Number was recalculated OK.
--- Modify the test mode 2a and 2b as a closed loop power transmission lines and transformer shunt current switching test test circuit, with
Increases under ground fault conditions breaking test test circuit (test mode 7a and 7b).
--- Remove the short-circuit during the test load switch may have been damaged and need to maintain content, such as replacement parts, updates off
Arc media or cleaning and adjusting the load switch is restored to its state before the test.
--- Nameplate information in accordance with China's actual made the appropriate changes, such as by GB/T 11022-2011 provisions of the rated short duration
Between the 1s to 2s.
--- Improve the "guide for the selection of the load switch," increases the load on the switch for a variety of applications and features, such as circuit breakers and replaced
Effectively limit GIS appearing fast transient overvoltage (VFTO) and GIS housing on the ground transient voltage (TVE) and the like.
This standard and GB/T 11022 used together, unless otherwise specified in this standard, this standard reference GB/T 11022. To simplify phase
Off it requires repeated statements, this standard reg number and GB/T 11022 same. Supplement these clauses references to the contents under the same title

This standard superseded standard previously issued as follows.
--- GB/T 14810-1993.
Rated voltage of 72.5kV and above AC load switch
1 Overview
1.1 Scope
This standard applies to the rated voltage of 72.5kV and above, rated frequency 50Hz, with a closing and breaking current ratings, for indoor
And three-pole AC load switch for outdoor installation.
This standard also applies to the actuator and its auxiliary equipment load switches.
Note 1. This standard covers gas-insulated metal-enclosed switchgear (GIS) in the load switch.
Note 2. The load switch with isolating function that is a load isolation switch should also meet the requirements of GB 1985.
Note 3. This standard does not cover the ground switch. As an integral part of the grounding switch load switch is included in the GB 1985.
The main objective of this standard is to determine the required load switches used in power transmission systems. Designed for this purpose to meet the common load switch
Run the following requirements.
--- Continuous support rated current;
--- Within the prescribed period of time carrying the short-circuit current;
--- Opening and closing power load current;
--- Opening and closing load transformer;
--- Opening and closing load cable charging current overhead lines or bus;
--- Closed-loop closure;
--- Closing short-circuit current.
Higher goal of this standard is to determine the specific requirements and special purpose load switches used in power transmission systems.
Dedicated load switch should meet one or more of the above operating conditions.
In addition to the special purpose load switch load switch to meet the universal one or more operating conditions, but also to meet one or more of the following conditions.
--- Opening and closing single capacitor bank;
--- Open and close back to back capacitor bank;
--- Combined open linked reactors, including the opening and closing of the primary side of the transformer from the secondary or tertiary winding side shunt reactors;
--- Requires operating cycles to improve working conditions;
--- Under a neutral non-effectively grounded system ground fault condition of opening and closing.
