A Simple Closure Device of Isolating Esplosion Switch

摘要

Currently, the power supply and control equipment of China' coal are widely used flameproof. Although it play a very important role in the production, because of the deficient of its structure and technical when workers in illegal operations it can't timely cut off the power and in all probability produce electric spark that can cause a serious gas explosion accidents. This paper gives a brief introduction of closure device of the small isolate explosion switch which can automatically cut off the power when the workers in illegal operations. Thus it can fully guarantee the switch won't produce electric spark whenever the workers in illegal operations.
