Automatic door opening and closing structure for high-voltage cabinet

Abstract

The invention provides an automatic door opening and closing structure for a high-voltage cabinet, and the structure comprises a cabinet body and a door plate, which form a closed cavity of the high-voltage cabinet. One surface, inside the cavity, of the door plate is fixedly provided with an inner door ring, and one surface, outside the cavity, is fixedly provided with an outer door ring. An inner side wall of the cabinet body is fixedly provided with a spring, and the spring tensions the inner door ring through an inner stay rope. The back surface of the cabinet body is fixedly provided witha coil, and the interior of the coil is provided with a magnetic moving block in a sleeving manner. An end part of the magnetic moving block is fixed at the rear end of an outer stay rope. A corner of an outer side wall of the cabinet body is fixedly provided with a pulley block. The outer stay rope is limited at the pulley block, and the front end of the outer stay rope is fixed at an outer pullring which sleeves the outer door ring. Through the setting of the spring, the coil and the pulley block, the door plate of the high-voltage cabinet can be opened under the condition that the power does not fail, so that an operator observes the condition of the interior, thereby greatly facilitating the maintenance. When the operator observes that the condition of the interior is good, the maintenance can be avoided, thereby avoiding the high cost caused by the frequent cut-off of power.

Description

technical field [0001] The invention relates to an automatic opening and closing door structure of a high-voltage cabinet. Background technique [0002] High-voltage switchgear refers to the function of on-off, control or protection in the power generation, transmission, distribution, power conversion and consumption of the power system. And grounding switch, high-voltage load switch, high-voltage automatic recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear and other major categories. The switch cabinet has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly applicable to various places such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mines, residential quarters, and high-rise buildings. [0003] However, due to the high voltage of the l...

Problems solved by technology

[0003] However, due to the high voltage of the line in the high-voltage cabinet, when there is a leakage in the line in the high-voltage cabinet, it may cause the cabinet itself to become a little bit. At this time, people may be electrocuted and killed if they pull the door. In order to prevent this from happening, the existing The technology is generally to cut off all the power first and then carry out maintenance, and then the result of all power off is that all work on the relevant lines will stop, and the cost is extremely high
