Automatic dust collection device for ventilation screen of high-voltage room in transformer substation

Abstract

The invention relates to an automatic dust collection device for a ventilation screen of a high-voltage room in a transformer substation and belongs to the technical field of power transformation operation and maintenance. The automatic dust collection device comprises a drive mechanism and a dust collection mechanism. The drive mechanism comprises a direct-current permanent magnet motor, a worm and a worm wheel. The direct-current permanent magnet motor is connected with the worm. The worm drives the worm wheel to rotate. The eccentric rotating point on the worm wheel is connected with a linkage rod mechanism. The linkage rod mechanism is connected with the dust collection mechanism. The automatic dust collection device is compact in structure, small in occupied space, convenient to adjust and use and capable of removing dust on the ventilation screen effectively, and power transmission trends to be simple; a lot of manpower and material resources are saved, and the ventilation quantity of a ventilation opening is increased; and the temperature and the humidity of the high-voltage room are improved, and normal operation of the device is guaranteed.

Description

technical field [0001] The invention relates to an automatic dust removal device for a ventilation network in a high-pressure room of a substation, and belongs to the technical field of substation operation and maintenance. Background technique [0002] At present, most of the substation electrical equipment is in the high-voltage room, but due to the requirements of the operating environment, especially the requirements of the equipment on the indoor temperature and humidity, vents and exhaust fans have become indispensable accessories in the high-voltage room. Due to the influence of the environment, a large amount of dust will enter the high-pressure room through the air outlet and adhere to the ventilation net, resulting in poor ventilation, which will affect the temperature and humidity in the high-pressure room, and cause short-circuit failure of equipment condensation. In order to ensure the normal operation of the equipment, the operation and maintenance department i...
