Anti-false-opening and anti-explosion distribution box

Abstract

The invention discloses an anti-false-opening and anti-explosion distribution box which comprises a box body, wherein a door is arranged on the box body, a sealing strip is arranged on the door, a toggle switch which controls the distribution box main circuit is arranged in the box body, a magnetic push rod is arranged on the side surface of the toggle switch in a sliding manner, a through hole isformed in the magnetic push rod which is sleeved with a toggle rod of the toggle switch, a magnetic sliding block which is attracted with the magnetic push rod mutually is arranged on the outside ofthe box body, a socket is arranged on the door, an electromagnetic push rod is arranged on the box body, a wedge block is arranged at the end part of the electromagnetic push rod, when the electromagnetic push rod is powered on, the wedge block is inserted into the socket and the door is tightened with the box body, the electromagnetic push rod is connected to the circuit of the box body, and whenthe electromagnetic push rod is powered off, the wedge block quits the socket. According to the distribution box, the door of the distribution box can be effectively prevented from being opened by mistake, the power supply is prevented from being switched on by mistake when the door of the distribution box is opened, and explosion is avoided.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to an anti-mis-opening explosion-proof distribution box. Background technique [0002] Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution box; On or off the circuit; when there is a fault or abnormal operation, the circuit is cut off or the alarm is cut off with the help of the protective device; various parameters in the operation can be displayed by means of the measuring instrument, and some electrical parameters can also be adjusted to prompt or send out the deviation from the normal working state. Signal. The distribution box can reasonably distribute electric energy, facilitate the opening and closing operation of the circuit, has a high level of safety protection, and can intuitively displa...

Problems solved by technology

[0003] Existing explosion-proof distribution boxes are generally only equipped with warning signs. When the distribution box needs to be operated or maintained, the distribution box can be opened directly, and the circuit can also be connected when the box is opened, which leads to the explosion of external explosive gas. Directly in contact with the distribution box, an explosion accident occurs, so the safety is very low
