Anti-explosion time delay switch for safety voltage

Abstract

The invention provides an anti-explosion time delay switch for safety voltage. The switch comprises an anti-explosion box, a power module, a timing module and a driving module. The power module comprises a rectifier bridge unit, a filter capacitor unit and a voltage stabilizing chip. Current is processed through the filter capacitor unit and the voltage stabilizing chip after passing through the rectifier bridge unit. The timing module comprises a 555 timing circuit, and the working power source of the timing module is supplied by the power module. The driving module comprises solid state relays comprising thyristors and optical couplers. The anti-explosion time delay switch for safety voltage is connected in series inside a circuit, and an existing mechanical switch is replaced with the anti-explosion time delay switch. The anti-explosion time delay switch for safety voltage can be automatically turned off in a time delay mode, and equipment using costs, maintaining costs, production-stopping maintaining costs and other related costs are lowered. Under the condition that the original circuit is not changed, the switch can be connected in series inside the circuit without the modification work of additional power lamp connection. The anti-explosion time delay switch for safety voltage is installed in the anti-explosion box, so that the anti-explosion using environment is obtained.

Description

[0001] technical field [0002] The invention relates to a switch, in particular to a safety voltage explosion-proof time-delay switch. Background technique [0003] At present, the safety voltage lighting uses mechanical switches. When the relevant personnel turn on the switch during inspection and inspection, sometimes they forget to turn off the switch, which causes the transformer and the bulb to stay on, wasting electric energy. In addition, the transformer and light bulb are used all the time, reducing the useful life of both. [0004] In view of this, it is necessary to propose further solutions to the above problems. Contents of the invention [0005] The purpose of the present invention is to provide a safe voltage explosion-proof time delay switch. [0006] In order to achieve the purpose of the above invention, a safety voltage explosion-proof time-delay switch of the present invention includes: an explosion-proof box, a power module, a timing module, and a dr...
