Abstract

The invention relates to a operating mode and operating control mechanism of electrical switch, which adopts the electromagnet force and the permanent magnetic force generated by a group of permanent magnet and a electromagnet coil to overcome force component of energy accumulation lock-dividing mechanism; it disconnects the holding circuit of the electromagnet coil so that the generated electromagnet force disappears; the lock-dividing force of the energy accumulation lock-dividing mechanism overcomes the electromagnet force to do lock-dividing. The resultant force can be aerodynamic, oil-pressure force or electromagnet force. It cuts of the holding current of the electromagnet coil when it does lock-dividing; it uses the lock-dividing force to above the permanent magnetic force to achieve the lock-dividing after the electromagnet force disappears.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to an electrical switch manipulation control method and manipulation control mechanism. Background technique [0002] At present, in petrochemical, mining, railway, electric power and other industries, the basic operation and control methods of closing and opening of the electrical switchgear used for opening and closing various feeder lines are nothing less than the following: : [0003] 1. Mechanical manipulation control mode, commonly known as the spring operation mechanism control mode, this manipulation control mode uses a mechanical lock to maintain the closing, and the opening mechanism acts to open the gate after tripping. For example, the disclosed "operating mechanism of switchgear" in Chinese Patent Publication No. CN2033542 adopts such a manipulation control method. It can be matched with a vacuum interrupter to form a vacuum circuit...
