Embodiment Construction

[0013] Regardless of whether it is 380V or 220V and other unsafe voltages, only the power line of one of the voltages is allowed to be connected to the input terminal of the mutual inductance transformer, and the safe voltage is output through the transformer, and the cable of the output safe voltage is connected to the explosion-proof lamp. on, it is safe to use. It is also possible to use no transformer, and the explosion-proof lamps are directly connected to the safe voltage power supply output by the battery or generator, as well as other safe voltage power supplies, which can also prevent electric shock, explosion and fire accidents.

Abstract

This invention relates to multi-function safety voltage anti-explosion light suitable for moist or inflammable locations, which comprises cable, inductor transducer, anti-inflammation lamp, fix or movable lamp rack, wherein, transducer converts voltage on 380V or 220V and other dangerous voltage into safety voltage; the lamp adopts anti-inflammation and anti-water, dust lamp; its process doesn't join power line into input line of transducer through induction transducer output to prevent fire affairs.

Description

Technical field [0001] The invention belongs to an electric shock-proof, explosion-proof and fire-proof lighting fixture used in inflammable and explosive places. technical background [0002] At present, in oil exploration and workover operations, the lighting fixtures used at night are all 220V ordinary non-explosion-proof lamps. Drilling and workover operations are all open-air flammable, explosive and humid places. Explosion and fire accidents can be caused by using ordinary lighting fixtures. It can also cause personal electric shock accidents, and fatal accidents have occurred in history. Contents of the invention [0003] Because in the past in the open-air flammable, explosive and humid places, ordinary lamps with a voltage of 220V are usually used, which are very prone to explosion, fire and personal electric shock accidents. [0004] In order to overcome the shortcomings of ordinary lighting fixtures, this safe voltage explosion-proof lighting fixture is specia...
