Abstract

An explosion-proof anticorrosive power light distribution box belongs to a power distribution box technical field. The structure is composed of a box, a cover, a wiring cavity and a main cavity, both ends of the box is respectively provided with a lighting outlet, a power outlet and a service entrance, the main cavity is divided in a plurality of chamber, each chamber is respectively provided with an independent cover on which an independent switching mechanism is arranged. The utility model has the advantages that the examination and repair are convenient, the adjustment for circuit branch is easy, and the electrical apparatus element can be changed as required, the cavity of the box is large and can be operated easily; the circular shaft switching mechanism can drill through the flameproof cavity and which is easy to be debugged. The utility model is applicable for the dangerous places with explosive gases, mixture and others, and the control power equipment and distribution facilities in the oil refining, chemical, pharmaceutical production environment.

Description

Explosion proof and corrosion protection power and lighting distribution box

Technical field

The utility model belongs to the distribution box technical field, particularly a kind of explosion proof and corrosion protection power and lighting distribution box.

Background technology

The structure of traditional explosion-proof electrical distribution box is single cavity list lid formula, and the box house cavity volume is too narrow little, is difficult for the multiple electric component of device; And casing, case lid all adopt the boiling steel hot rolled plate, make the strong drag of the outside anti-mechanical shock of distribution box not enough, inner compression resistance deficiency.If a circuit in the distribution box has fault, need open full case, the electrified body many places are exposed, use inconvenience, the explosion proof and corrosion protection poor performance.

The utility model content

In order to solve the problem of above-mentioned existence, the utility model provides a kind of explosion proof and corrosion protection power and lighting distribution box.It comprises casing, case lid, wire connection cavity, main chamber, the two ends of casing are furnished with illumination line outlet, power line outlet and power incoming line respectively, main chamber is divided into a plurality of chambers by dividing plate, be separately installed with separate case lid on each chamber, separate switching mechanism is installed, energising, the outage of control internal electric source on the case lid.Switching mechanism comprises switch fixed head, slider disc, square hole plate pin, square heart rotating shaft and wear-resisting copper sheathing and handle, slider disc is that U type block is installed in the side of U template, its U type block places the both sides of electric switch, the big end in square hole plate pin cross section is by being bolted on the slider disc, the little end in cross section is installed in the circular hole of switch fixed head, heart roller end little end in side's is installed in the square hole of square hole plate pin, the square heart rotating shaft that wear-resisting copper sheathing is installed on every side places case lid, at the other end of the square heart rotating shaft handle is installed.The material of anti-wearing liner is a pltine, and casing and case lid all can adopt corrosion resistant carbon constructional steel plate, and electrostatic spraying forms, and perhaps adopts the stainless-steel sheet of anti-strong acid to be welded; Can install may command electric components such as circuit breaker, relay, contactor and earth leakage protective device in each cavity in the casing, reach lighting device, air draft, heating, air-conditioning harmony visual alarm device etc. and can control electrical equipment, be convenient to remote operation and control.

Its course of work: promote handle, make square hole plate pin enter into switch fixed head inside, and can slide along its inwall, the heart rotating shaft of the rotating handles side of drive, square hole plate pin and slider disc rotation make energising, the outage of slider disc control electric switch.

The utility model has the advantages that convenient maintenance, easily adjust the electrical equipment branch road, can arbitrarily change electric elements, the casing cavity volume is big, and is easy to operate; Switching mechanism is the circular shaft formula, runs through explosion-proof chamber, easily debugging.Be applicable to hazardous areas such as damp, mixture, reach control power-equipment and distribution facility in oil refining, chemical industry, the pharmaceutical manufacturing environment.
