Abstract

A multifunction safe voltage anti-explosion lighting lamp includes cables, isolating switch, mutual inductance transformer, an anti-explosion lamp, a fixed or movable frame, which van turns 380V or 220V or other unsafe voltage to safe, namely, 36V, 24V or 12V or other safe voltages. The process is as follow: A power supply line of 220V or 380V or other unsafe voltage is connected to the input line of the mutual inductiont ransformer, only one enough, the unsafe voltage is changed to safe one.

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...
