Static Switching System (STS) Part 2. Electromagnetic compatibility (EMC) requirements1 ScopeGB/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 for interrupted or uninterrupted controlled switchover. GB/T 34940 includes the switching element and its control and protection components (if applicable) requirements, including the STS and its accessories Integrated information into the AC grid. GB/T 34940 This section applies to the AC voltage does not exceed 1000V single-phase, two-phase and three-phase static switching system. This section takes precedence over all aspects of common performance standards and requires no additional performance tests. These requirements are selected to ensure that STS has adequate EMC levels in public or industrial locations. However, these levels Can not cover extreme situations that can occur anywhere, but with a low probability of occurrence. These requirements take into account the different test conditions necessary for the coverage of the STS physical size and power rating data. Regardless of whether it is a unit of equipment or a combination of units, STS as a standalone product should meet the requirements of this section. But any power supply or The EMC phenomenon that occurs when the load is connected to the input or output of an STS device should not be taken into account. This section does not apply to. --- Switching DC source device; --- Single AC source system; --- Only use the electromechanical switching device to allow the interruption of the load power supply during switching and is intended for static switching of the emergency power supply system system; Note 1. This type of equipment is covered by IEC 60947-6-1. --- Integrated in the UPS, is covered by GB/T 7260 automatic switching device. Note 2. Scheduled for use in vehicles, boats, aircraft, tropical areas, emergency power supplies (eg for medical facilities, firefighting and emergency assistance, etc.) or altitude STS above 1000m may have different requirements. This section is for electromagnetic compatibility (EMC) requirements. General and safety requirements see GB/T 34940.1. This section does not cover the special installation environment, nor does it account for STS failure conditions. This section provides. --- EMC requirements; ---experiment method; --- The lowest level of performance.2 Normative referencesThe following documents for the application of this document is essential.
