Spring power self-locking device of arc extinction switch

Abstract

The invention provides a spring power self-locking device of an arc extinction switch. The spring power self-locking device of the arc extinction switch is composed of a first spring, a second spring, a third spring, an insulating rod, a baffle, a self-locking block, a connecting tube, a static plum blossom contact, a moving plum blossom contact, a first operating rod, a second operating rod, a first clamping pin, a second clamping pin and an insulating cylinder, wherein a key device on the self-locking block is composed of a dowel, a self-locking sliding block and marbles. Two spring systems of the spring power self-locking device of the arc extinction switch complete energy storage and energy release through independent actions, namely, energy storage of one set of springs is completed through primary operation, and energy storage of the other set of springs is completed through secondary operation; through the design, the spring power self-locking device provides energy for quick closing and disconnection of the arc extinction switch, so that the arc extinction switch has the two functions, the use convenience of the arc extinction switch is improved, and a good basis is laid for popularization and application of the arc extinction switch.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a spring power self-locking device for an arc suppression switch. Background technique [0002] With the large-scale expansion of cities and the wide application of power cables, there are more and more overhead and power cable hybrid lines, and the requirements for arc suppression methods and arc suppression equipment for live work in distribution networks are also getting higher and higher. At present, in addition to the arc suppression equipment developed by each power supply company, there is a shortage of arc suppression equipment specially used for live work in distribution networks. The most common one is the "Bodhisattva" line jumper of the U.S. company Uslow. However, limited by the opening speed of the operating mechanism, it does not have the ability to break large capacitive currents, which severely restricts the live work of hybrid distribution lines. In orde...
