Research on Series-parallel Structure Vacuum Circuit Breakers
摘要
Abstract
This paper presents a new design of large-capacity high-voltage breakers base on series-parallel structure vacuum circuit breakers. In this design, 126 kV high-voltage circuit breakers is composed of 40.5 kV circuit breakers module by capacitance, a tightly-coupled reactor which has a small consumption in normal working state is adopted to connect with two paralleled breakers. This combination can effectively achieve the function of automatically current-sharing and current-limiting. The working principle of the design is verified through research tests. Including the insulation testing, paralleled and limiting current testing, break testing,verify the operation of machinery, and analysis of test data.关键词
