Abstract

The utility model discloses an intrinsic safety type reactive power compensation device explosion-proof box which can be opened conveniently. The intrinsic safety type reactive power compensation device explosion-proof box comprises a box body and a box door. The outer sidewall of the box body is provided with reinforcing ribs. The box body is provided with an electric brake rotating handle. A mouth-shaped box body flange and a box door flange are fixed on the contact surface between the box body and the box door separately. The box door and the box body are connected through a horizontal sliding hinge. The intrinsic safety type reactive power compensation device explosion-proof box of the utility model has following technical effects that firstly, the mouth-shaped box body flange and the box door flange are fixed on the contact surface between the box body and the box door separately, and the box body flange and the box door flange are provided with a flange clamping base, so the tight closing of the box body and the box door can be ensured so as to prevent sparks from appearing; secondly, in the maintenance process, the rotating handle is rotated, an eccentric horizontal sliding pin on the end surface of a horizontal sliding rotating shaft is clamped into a clamping slot, so the box door hinge base and the box door are pushed by the horizontal sliding rotating shaft so as to be in translation to the right, and the flange clamping base is disengaged from the flange, so the box door can be opened conveniently; thirdly, a stopping device is arranged between the electric brake rotating handle and the box door sidewall, so the box door only can be opened when the electric brake rotating handle is in the closing state, so that the safety can be ensured.

Description

Open intrinsic safety type reactive power compensator Flameproof box easily

Technical field

The utility model relates to the intrinsic safety type reactive power compensator Flameproof box used under a kind of coal mine.

Background technology

Under coal mine, owing to there being the flammable explosive gas such as gas, according to the GB requirement, the down-hole electric equipment must have explosion insulation performance.So-called flame proof, be exactly structurally by quarantine measures, that circuit and surrounding environment is isolated, the heat that circuit was produced in when normal operation and the electric spark and the high temperature that form during at fault case, within all being limited in the housing of sealing, with prevent around flammable explosive gas ignite.The general Flameproof box formed by Plate Welding that adopts carries out flame proof at present.For the requirement of installation and maintenance, Flameproof box generally has door, can open and close.Requirement to the flame proof door is: door flange fineness reaches GB, between door and casing, wants tight closure, prevents that spark from scurrying out.The flameproof enclosure of down-hole reactive power compensator generally adopts the screw door at present, on whole exactly door, there is 9-12 bolt to guarantee door and casing tight closure, although this mode can meet the flame proof requirement, but bolt is too many, dismounting is consuming time, the switch gate inconvenience, the repair time is long, remote-effects down-hole normal power supply.
