验证了设计的有效性

为混合式高压直流断路器的实现提供了保证。

Abstract

In a HVDC circuit breaker system

total fault clearing time is mainly dependent on the reaction time of the ultra-fast disconnect switch（UFDS）. Based on the principle of electromagnetic repulsion mechanism（ERM）of UFDS

the finite element model of electromagnetic repulsion mechanism is established in this paper. In addition

by means of systematic and comprehensive simulations

the influence of the parameters of the coil and the size of the metal plate on the dynamic characteristics of UFDS is simulated and analyzed

and based on this the parameters of ERM are optimized. Finally

a prototype of UFDS based on ERM is built. A series dynamic characteristic test results show that the designed ERM can meet the requirements of transient interrupt voltage（TIV）insulation distance during the fault cleaning process UFDS 2 ms. According to the experiment results

the simulation results are in good agreement with the experimental observations

which guarantee for the realization of hybrid HVDC CB.
