Problems solved by technology
[0002] At present, the energy storage mechanism of the load isolating switch group mainly relies on single torsion and compression springs. The opening and closing processes are all realized by the energy storage and release of the same torsion spring. The tripping function cannot be realized, the opening and closing speeds cannot be controlled separately, and there is no remote breaking. Function

The invention discloses a shunt tripping system used for an electrical appliance switch. The system comprises a tripping support, a switch connection rod, an operation connection rod, a first press spring, a second press spring, a triggering linkage mechanism and an electromagnetic tripping device. The operation connection rod is connected with the triggering linkage mechanism. The triggering linkage mechanism is connected with the switch connection rod through the first press spring. The switch connection rod is connected with the second press spring. The electromagnetic tripping device is connected with the triggering linkage mechanism. The first press spring and the second press spring are connected with the tripping support. The switch connection rod is connected with a switch througha transmission mechanism. According to the invention, by use of double press springs, independent control of turning on and turning off processes of the switch is achieved; performance of the electrical appliance switch is improved; through the electromagnetic tripping device and the triggering linkage mechanism, tripping operation and remote tripping operation can be achieved; use safety of maintenance processes is improved; and furthermore, an energy storage system of a traditional load isolation switch group is abandoned, and through the four connection rod mechanisms and double press spring segmented type energy storage, separation and combination processes are quite stable and reliable; and separation speed and combination speed are independently controllable.
Description
technical field [0001] The invention relates to the field of electrical switches, in particular to a shunt tripping system for electrical switches. Background technique [0002] At present, the energy storage mechanism of the load isolating switch group mainly relies on single torsion and compression springs. The opening and closing processes are all realized by the energy storage and release of the same torsion spring. The tripping function cannot be realized, the opening and closing speeds cannot be controlled separately, and there is no remote breaking. Function. Contents of the invention [0003] In view of the above-mentioned shortcomings existing at present, the present invention provides a shunt tripping system for electrical switches, which has a compact structure and high reliability. [0004] In order to achieve the above object, embodiments of the present invention adopt the following technical solutions: [0005] A shunt tripping system for an electrical swit...
