Abstract

The invention discloses a GIS transient simulation electromagnetic interference source. The GIS transient simulation electromagnetic interference source includes a boosting transformer U1, a power side simulation capacitor C1, a circuit breaker, a power side outlet bushing A2, a sphere gap, an isolating switch, a load side outlet bushing A1 and a load side simulation capacitor. The circuit breaker, the sphere gap and the isolating switch are in series connection between the power side outlet bushing A2 and the load side outlet bushing A1 to constitute a main loop. An output end of the boosting transformer U1 is connected to the power side outlet bushing A2. The power side simulation capacitor C1 is connected to the power side outlet bushing A2 and is intended for simulating the power side capacitance of an actual transformer substation. The load side simulation capacitor C2 is connected to the load side outlet bushing A1 and is intended for simulating the GIS outlet load side capacitance of the actual transformer substation. According to the invention, the GIS transient simulation electromagnetic interference source can simulate the processes of transient electromagnetic interference and very fast transient overvoltage produced in the opening and closing of the circuit breaker and isolating switch in a GIS device, simulates in an actual manner an actual electromagnetic environment where an electronic device is, and makes testing result more real and reliable.
