Abstract
This paper discusses the disadvantages of moving contact loosing
escaping from the closing position because of the hard bus connection between the circuit breaker and the disconnector. The improvement of reforming the hard bus connection to a soft one between 40.5 kV circuit breaker and disconnector is made in Zhuozhou 220 kV substation. The author also gives the method to solve this kind of problem.
