Technical Field

The invention relates to the technical field of electrical equipment, in particular to a flame-retardant explosion-proof high-low voltage switch cabinet.

Background

The in-process of adding of explosion-proof mechanism is assembled to current cubical switchboard, can only realize through the change of spring assembly to the teaching with the bolster, and after long-term the use, also need directly to change when the elasticity of spring part is not enough simultaneously, has shortened life cycle.

For example, the application No. CN201811410272.3, publication No. CN109256713A discloses a switch cabinet top explosion-proof device and method, including a cabinet body and a partition board, where the partition board is provided with an explosion-proof membrane for releasing expansion gas in a space below the partition board, the partition board is connected to the top of the inner wall of the cabinet body through a buffer assembly, the buffer assembly includes a baffle, a first spring, an electric push rod and a contact switch, when the pressure of the expansion gas in the space below the partition board exceeds a set pressure value of the explosion-proof membrane, the expansion gas is discharged from the explosion-proof membrane and pushes against the baffle, the baffle moves upward to compress the first spring and close the contact switch at a set stroke, so as to control the electric push rod to contract its push rod to move the partition board upward, and the expansion gas is discharged outward from exhaust windows arranged on two sides of the upper portion of the cabinet body; this device can release its fast away when producing quick great expanding gas in the cubical switchboard, has effectively avoided the blasting damage of cubical switchboard. The initial flexible volume of first spring in this scheme just can not carry out the timing, can only change, can not satisfy the use that the interior different pressure of cubical switchboard required, can only set for initial pressure value, when electronic equipment breaks down or cuts off the power supply, the contact switch in the electrical equipment just can't work, causes great potential safety hazard, has not satisfied the user demand of people in the production life.
