Problems solved by technology

However, due to the large size of the coupling / decoupling capacitor and the coupling / decoupling inductor, the lightning surge generator with the built-in three-phase five-wire coupling / decoupling network is correspondingly large, and transportation and use are very difficult. inconvenient
[0004] In addition, since there are many coupling combinations of the three-phase five-wire system, it is difficult to realize the automatic switching of the coupling mode in the program control

Abstract

The invention relates to a coupling decoupling network lightning surge generator. The lightning surge generator comprises a host machine and a coupling decoupling network device, and the host machine is connected with the coupling decoupling network device through a parallel interface input/output wire. Compared with lightning surge generators in prior art, the coupling decoupling network lightning surge generator has the advantages that the size is small, the usage is convenient, the automatic switching control of the coupling mode in terms of programs is achieved, and the like.

Description

technical field [0001] The invention relates to a lightning surge generator, in particular to a coupling decoupling network lightning surge generator. Background technique [0002] Natural lightning strikes and high-energy pulses generated by switching actions in transmission lines will have a great impact on the reliability of electronic products. Therefore, it is necessary to conduct lightning surge tests. The anti-surge performance test of industrial process measurement and control equipment is to simulate the voltage and current surges caused by lightning strikes or switch switching processes that equipment may encounter under different environmental and installation conditions. [0003] In order to truly simulate lightning strikes and switching transients, and to make the test results more comparable and reliable, the performance of lightning surge generators has been improved in recent years. From the built-in single-phase three-wire coupling / decoupling network to the...
