The invention provides an integrated combination device of a circuit breaker isolation switch. The integrated combination device comprises a first isolation mechanism, a first connecting rod, a second connecting rod, a second isolation mechanism, an operation connecting rod, an execution mechanism, a conductive connecting rod, a moving contact, a static contact, a static contact fixing rod and a metal scribing piece. One end of the first connecting rod is connected with the first isolation mechanism, and the other end of the first connecting rod is connected with the second connecting rod; the first connecting rod is connected with the second isolating mechanism through a second connecting rod; one end of the operation connecting rod is connected with the second connecting rod, and the other end is connected with the execution mechanism; one end of the conductive connecting rod is connected with the second connecting rod, and the other end is connected with the moving contact; one end of the static contact fixing rod is fixed on the switch cabinet, and the other end is connected with the static contact; and the metal scribing sheet is vertically fixed on the fixed contact fixing rod. According to the present invention, the disconnecting switch and the circuit breaker are designed into an integrated element, so that the structure is simplified, the cost is reduced, and the operation reliability of the system is improved.
Description
technical field [0001] The present application relates to the technical field of electrical switchgear devices, in particular to an integrated combination device of a circuit breaker isolating switch. Background technique [0002] High-voltage switchgear mainly plays the role of control, protection and safety isolation in power grid control, and also plays the role of carrying rated current in power transmission. The safety and stability of high-voltage switchgear will directly affect the safe operation and reliable power supply of the entire power grid. Among them, the switchgear is one of the most important high-voltage switchgears in the distribution network, which is widely used in the power system. [0003] Circuit breakers and isolating switches are important components in the design of substation switchgear, and they are usually used independently to perform different functions. A circuit breaker is a mechanical switching device that can close, carry and break curre...
