Static Switching System (STS)
Part 1. General and safety requirements
1 Scope
GB/T 34940 is suitable for stand-alone operation, scheduled to ensure continuous power supply load AC Static Switching System (STS). The system is two
Or multiple independent AC source automatically or manually interrupted or uninterrupted controlled switch.
This section GB/T 34940 specifies the general principles and safety requirements. Electromagnetic compatibility (EMC) requirements see GB/T 34940.2, certainty
To methods and test requirements can see GB/T 34940.3.
The purpose of this section is to reduce the risk of fire and electric shock, as well as installation, operation and maintenance of equipment in the manner specified by the manufacturer
Risk of personal injury.
This section includes the switching element and its control and protection components (if applicable) requirements, including access to STS and its accessories exchange
The overall information of the grid.
STS in order to achieve the operation, control, protection, isolation of the necessary components or devices (such as circuit breakers, fuses, transformers, etc.)
Should meet the requirements of the relevant standards, this section does not cover.
This section applies to AC voltage not exceeding 1000V single-phase, two-phase and three-phase static switching system.
This section does not apply to.
--- Switching DC source device;
--- Only use the mechanical and electrical switching devices to allow the load during the switching process power supply interruption, and is intended for emergency power supply system, the static switching system
System. Such equipment is covered by IEC 60947-6-1;
--- Integrated in the UPS, by the national standard "uninterruptible power supply (UPS)" covered by the automatic switching device.
Note. Scheduled for vehicles, boats, aircraft, tropical areas, emergency power supply systems (eg for medical facilities, firefighting and emergency rescue, etc.) or at an altitude of 1000m
STS in the above areas may have different requirements.
