A 110kv substation ground wire intelligent control cabinet

Abstract

An intelligent control cabinet for grounding wires of a 110kV power substation comprises a cuboid vertical cabinet body. Double cabinet doors or a single cabinet door matched with the cabinet body is installed on the front face of the cabinet body through gemels or hinges located on the side edge of the cabinet body. High-strength transparent tempered glass is arranged on the front faces of the double cabinet doors or the front face of the single cabinet door. A cabinet exterior temperature and humidity sensor is installed at the top of the cabinet body. An intra-screen illuminating lamp and a cabinet interior temperature and humidity sensor are installed at the top of the interior of the cabinet body. An electric special dehumidifier CSQ, a PTC electric heater JRQ and a direct-current fan are installed at the bottom of the interior of the cabinet body. The cabinet exterior temperature and humidity sensor, the intra-screen illuminating lamp HL, the cabinet interior temperature and humidity sensor, the electric special dehumidifier CSQ, the PTC electric heater JRQ and the direct-current fan are connected with a temperature and humidity controller. The interior of the cabinet body is divided into a left storage space and a right storage space through a vertical partition plate located in the middle of the cabinet body.

Description

technical field [0001] The invention relates to a 110kV substation grounding wire intelligent control cabinet, which belongs to the technical field of safety tool cabinets. Background technique [0002] The grounding wire plays an important protective role for the safety of the staff in the actual operation, maintenance and repair of the power system. . However, if it is used and managed improperly, it may cause serious misoperation accidents. According to the latest statistics of State Grid Corporation of China and statistical data of the past years, the incidence of malignant misoperation accidents with temporary grounding wire (grounding switch) closing has always been the first (60%) of all kinds of malignant misoperation accidents. Therefore, the strict storage and standardized management of the ground wire is of great significance to reduce the occurrence of misoperation accidents related to the ground wire. At present, it has also been paid more and more attention ...

AI Technical Summary

Problems solved by technology

At present, for the placement of the grounding wire, most of them do not have a unified special tool cabinet, and the storage environment does not meet the requirements of the grounding wire. Often, the safety performance of the grounding wire is affected due to the humidity of the surrounding environment, and the grounding wire is oxidized. Even if some cabinets have functions such as heating and dehumidification, they cannot be remotely monitored and controlled online, and abnormal temperature, humidity and temperature in the cabinet cannot be detected in time, or abnormal operation of heaters and dehumidifiers can be detected, which also makes the safety performance of the grounding wire Affected, affecting the safety of the power system on-site work, forming a safety hazard
