Description
Technical Field
The utility model relates to an epoxy cabinet, concretely relates to take permanent magnetic mechanism's looped netowrk cabinet.
Background
At present, a spring operating mechanism and an electromagnetic operating mechanism used in a ring main unit are complex in mechanism, complex in process, high in cost and difficult to guarantee reliability. When the power system normally operates, the working current flowing in the circuit is generally below 400A, the current is small, and the circuit breaker is closed through the operating mechanism, so that the circuit breaker is easy to close. However, when short-circuit accidents occur, the short-circuit current in the circuit can reach 40kA or even more. The operating mechanism must overcome over thousands of newtons of electrodynamic force to close the circuit breaker, which is very difficult.
When the circuit breaker is opened, an electric arc appears, the larger the opening current is, the harder the electric arc is to extinguish, and the more severe the working condition is. When the alternating current voltage crosses zero, the current between the moving contact and the static contact of the circuit breaker can not change suddenly at the moment of separating the moving contact and the static contact, and transient recovery voltage can appear. For the purpose of breaking the circuit, the operating mechanism must provide a certain opening speed, in particular a just opening speed.
