Special cabinet for transformer substation operation and maintenance safety tools

Abstract

The invention discloses a special cabinet for transformer substation operation and maintenance safety tools, which comprises a cabinet body, a left cabinet door, a right cabinet door and drawers. Thelower left side of the cabinet body is divided into upper and lower layers, the upper layer is a place where insulating gloves are placed, the lower layer is a place where insulating boots are placed,and the lower right side of the cabinet body is a place where an electroscope and an insulating rod are placed; each drawer is provided with a handle, the left cabinet door is provided with a left cabinet door locking device, the right cabinet door is provided with a right cabinet door locking device, the left cabinet door locking device and the right cabinet door locking device are controlled bya locking control circuit; and a particle sensor, a temperature and humidity sensor, a purifying filter net, a heating humidifier and a fan are arranged in the cabinet body, the purifying filter netand the fan are respectively arranged on the left side face and the right side face of the cabinet body, the particle sensor, the temperature and humidity sensor are connected with the input end of acontrol unit, the output end of the control unit is connected with the heating dehumidifier and the fan, and the fan is provided with a fan filter. The cabinet avoids the influence of temperature andhumidity on the insulating rubber, and adopts a forced locking device to ensure safe operation and maintenance.

AI Technical Summary

Problems solved by technology

[0002] The safety tools used in substation switching operations need to be fixed and placed in the safety tool cabinet. The traditional safety tool cabinet only has a simple layout of the internal structure of the cabinet, which is convenient for the fixed management and pick-and-place of various safety tools. Failed to resolve the following issues:

[0003] 1. The sealing performance of the cabinet door is not good. The dust brought by the substation reconstruction and expansion project and the poor outdoor air quality will bring pollution to the tools and appliances in the cabinet and affect its insulation performance; the increase of environmental humidity in the southern rainy season also affects its insulation performance , the adhesion of dirt and water vapor will also accelerate the aging of tools

[0004] 2. There is no heating and dehumidification device in the cabinet. If the temperature is too low in winter, the insulating rubber will harden and affect the insulation performance of insulating boots and gloves; if the humidity in the cabinet is too high, it will affect the insulation performance of insulating rods.

[0005] 3. There is no heat dissipation and dust removal device in the cabinet. Excessively high temperature in summer will accelerate the aging of insulating rubber and affect the service life of insulating boots and insulating gloves. Opening the cabinet door during daily use will easily cause dust to fly in. If the sealing performance of the cabinet door is not good , it is easy to cause dirt on the surface of the safety tools in the cabinet, which affects the insulation performance

[0006] 4. There is no mandatory locking measure when the safety equipment in the cabinet expires, and the negligence of the personnel in the inspection of the safety equipment may easily cause the overdue use of the safety equipment and bring certain safety hazards

[0007] In order to reduce the impact of temperature, humidity, dust, etc. on the life and insulation performance of safety tools and appliances, and to avoid safety hazards brought about by overdue inspection of safety tools and appliances, this invention develops a special cabinet for power substation operation and maintenance safety tools. Integrate functions such as air exhaust, dust removal, heating, dehumidification, and tool inspection overdue locking of the cabinet door to realize the improvement of the environmental conditions in the cabinet and reliable locking of the inspection overdue
