An industrial control cabinet

Abstract

The invention discloses an industrial control cabinet, which comprises a cabinet body and a cabinet door installed through hinges on the front side of the cabinet body. A through groove is opened on one side wall of the cabinet body, and a folding rubber sleeve is fixedly connected to one side of the through groove. The end of the folding rubber sleeve away from the through groove is fixedly connected with a moving plate, and the side of the moving plate away from the folding rubber sleeve is fixedly connected with a pull rod. One end of the pull rod runs through the other side wall of the cabinet and extends outward, and the top of the cabinet is fixedly connected There is an exhaust pipe, and the present invention is used in conjunction with a through groove, a folding rubber sleeve, a closed cavity, a moving plate, a pull rod, an exhaust pipe and a storage folding sleeve, and the pulling of the pull rod makes the moving plate unfold with the folding rubber sleeve. The inert gas inside the cabinet is squeezed into the storage folding sleeve, and the inner cavity of the cabinet is occupied by the unfolded folding rubber sleeve, so that only a small amount of inert gas remains, which will not have adverse effects on the human body when the cabinet door is opened later .

Description

Technical field [0001] The present invention belongs to the technical field of electrical equipment, and more particularly to an industrial control cabinet. Background technique [0002] The control cabinet is in accordance with the electrical wiring requirements to assemble the switchgear, measuring instrument, protective electrical and the auxiliary equipment in a closed or semi-closed metal cabinet or screen, and its arrangement should meet the requirements of the normal operation of the power system, which is easy to overhaul the person. And the safety of the surrounding equipment. The circuit can be turned on or disconnected by manual or automatic switches when operating properly. The circuit or alarm is cut off by means of the protection appliance when it is not normal. Borrow measuring instruments can display various parameters in operation, and some electrical parameters can be adjusted to prompt or send signals that deviate from the normal operating state. Commonly used ...

AI Technical Summary

Problems solved by technology

[0003] Explosion-proof electrical control cabinets are generally filled with inert gas for protection. When the cabinet is opened, the inert gas will escape, and careless operation will cause the staff to lack oxygen. In the prior art, the inert gas is generally extracted and injected into the air. The inert gas It is easy to mix with air, and the inert gas needs to be separated and purified again, and the efficiency is low
