Description

Explosion-proof malleation switch board

Technical Field

The invention relates to an electrical cabinet, in particular to an explosion-proof positive-pressure control cabinet, and belongs to the technical field of special power equipment.

Background

The control cabinet is formed by assembling switch equipment, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements, and the arrangement of the control cabinet meets the requirements of normal operation of an electric power system, is convenient to overhaul and does not endanger the safety of people and surrounding equipment. In normal operation, the circuit can be switched on or off by means of a manual or automatic switch. When the fault or abnormal operation occurs, the circuit is cut off or an alarm is given by the aid of the protective electric appliance. The measuring instrument can display various parameters in operation, and can also adjust some electrical parameters to prompt or send signals for deviating from normal working state, and the measuring instrument is commonly used in various power distribution, distribution and transformation substations.

In view of the above, chinese patent No. CN207801184U proposes an explosion-proof positive pressure control cabinet, which automatically controls the actual pressure in the cabinet through a pressure controller to ensure that the pressure in the cabinet is within a proper range, and is safe and stable, wherein a cooling pipe is arranged in the cabinet to assist in cooling the cabinet, and the fan and the partition plate effectively guide the air flow in the cabinet, so that the cooling effect is good; chinese patent No. CN207083338U proposes an intelligent positive pressure explosion-proof control cabinet, which blows the safe air into the positive pressure cavity in turn through the positive pressure blowing device and finally discharges the air through the exhaust control valve, so that the air pressure in the control cabinet is higher than the external air pressure, a small safe environment of micro-positive pressure is formed, the flammable dangerous gas is prevented from entering, and the safe operation of the electrical appliance element is ensured; the invention provides an explosion-proof positive pressure cabinet with Chinese patent number CN209250985U, which can quickly dissipate heat, solve the technical problem that the positive pressure cavity of the existing positive pressure cabinet is easy to rise, and ensure the safety of electrical equipment. But the junction of the cabinet door of the switch board in the above-mentioned patent and the cabinet body has great space, blocks up it through sealed pad among the prior art, but sealed pad in long-time use, because frequent push-and-pull cabinet door can lead to the damage of sealed pad, and local fracture, lead to outside gas or dust to get into the cabinet body

Inside, if a short circuit occurs, the cabinet may explode.
