Verification Experiment of Simulating the Effect of Quarantine Source on Isolated Switch

摘要

In order to simulate the actual scene of the harsh electromagnetic environment in the substation, and then study on electromagnetic compatibility testing of electronic instrument transformer, an isolated switch simulation source system is developed to promote the standardization of the original test based on the original isolation switch as a harassment source of the electronic instrument transformer electromagnetic compatibility test system. In this paper, the circuit breaker is used to control the opening and closing of the gap arc to simulate the operating of isolating switch, and the isolation switch simulation harassment source system is designed accordingly. Compared with the actual test results of the isolating switch, it is proved that the system can meet the test requirements, and the simulation harassment source system has good stability and high reliability. Therefore, the proposed isolation switch simulation harassment source electronic transformer immunity test can replace the current "isolation switch sub-capacity of small current conditions under the electronic transformer immunity test" experiment and further promote the current electronic transformer performance testing of electromagnetic compatibility test standardization.
