How to correctly use explosion-proof control cabinets in explosive gas hazardous places, because electrical equipment inevitably generates electric sparks or forms hot surfaces during work, once they meet the explosive gas mixture on site, it will lead to explosion accidents generated, directly endangering the user's property and life safety
The prior art discloses an explosion-proof control cabinet that can open the door and cut off the power. When the door is opened, the explosion-proof control cabinet can automatically cut off the power supply in the cabinet, which has high safety. However, although the explosion-proof control cabinet can cut off the power supply instantly , but at the moment when the door of the control cabinet is opened, flammable and explosive gases from the outside can easily enter the cabinet, and there is still a great potential safety hazard

The invention discloses a linkage self-locking anti-explosion control cabinet. The cabinet comprises a cabinet body (1); a cabinet door (2) is rotationally connected to one side of the cabinet body (1); a mounting frame (3) which is vertically arranged is mounted at the bottom of the inner side of the cabinet door (2); a main power switch (31) is mounted on the mounting frame (3); and a locking device and a linkage device are mounted on the cabinet body (1). The cabinet has the advantages as follows: through the linkage device, the main power switch can be controlled to be turned off in a linkage mode when the cabinet door is closed on one hand, and the locking device can be controlled in a linkage mode through a contact switch to lock the cabinet door; after the explosion-proof control cabinet is electrified, the cabinet door can be locked; as long as the interior of the explosion-proof control cabinet is electrified, the cabinet door cannot be opened; the cabinet door can be opened only after the interior of the explosion-proof control cabinet is powered off; even if the locking device breaks down, the cabinet door is forcibly opened, and the main power switch is controlled to beturned off through the linkage device; and therefore, the cabinet is safe and reliable.
Description
technical field [0001] The invention relates to the field of electrical explosion-proof technology, in particular to a linkage self-locking explosion-proof control cabinet. Background technique [0002] With the rapid development of coal oil chemical industry, metal smelting, chemical pharmaceutical and other industries, explosion-proof control cabinets are more and more widely used in system control. How to correctly use explosion-proof control cabinets in explosive gas hazardous places, because electrical equipment inevitably generates electric sparks or forms hot surfaces during work, once they meet the explosive gas mixture on site, it will lead to explosion accidents Generated, directly endangering the user's property and life safety. The prior art discloses an explosion-proof control cabinet that can open the door and cut off the power. When the door is opened, the explosion-proof control cabinet can automatically cut off the power supply in the cabinet, which has hig...
