Abstract

The invention discloses an electromagnetic compatibility immunity testing device for control protection equipment. The device comprises an immunity testing signal generator used for outputting an immunity testing signal, a control protection device used for receiving the immunity testing signal, and a real-time simulation device connected with the control protection device and used for providing aworking signal for the control protection device, wherein the working signal port of the control protection device is connected with the working signal port of the real-time simulation device. According to the electromagnetic compatibility immunity testing device of the control protection equipment, the actual working condition of the control protection equipment can be completely reflected, andthe accuracy of electromagnetic compatibility immunity characteristic detection of the control protection equipment is improved.

Description

technical field [0001] The invention relates to the technical field of control and protection equipment, in particular to an electromagnetic compatibility immunity test device for control and protection equipment. Background technique [0002] With the development of the power system, the power system is becoming more and more electronic, informatized and intelligent, and the reliability requirements for control and protection equipment are also getting higher and higher. As an important performance index of control and protection equipment, electromagnetic compatibility has attracted more and more attention with the increasingly complex electromagnetic environment in the power system. [0003] Electromagnetic compatibility immunity test is a part of electromagnetic compatibility test, which means that the equipment has a certain degree of immunity to electromagnetic interference in the environment. The test standard requires that the control and protection equipment should...
