Abstract

The invention discloses a switch cabinet intelligent control device, which comprises a main control module STC89C52, a one-time dynamic simulation wiring module, a high-voltage electrification and lockout module, a temperature and humidity control module, a voice incorrect-prompt prevention module, a liquid crystal display module, a remote/in-situ conversion switch, an upper computer remote monitoring host and a fault diagnosis expert system module. The device is capable of explicitly showing the actual working state of each component in a switch cabinet and is high in safety performance. Based on the above remote monitoring technology, the working efficiency is greatly improved and the failure rate of the device is reduced. The maintenance period of the device is shortened and the application efficiency of the device is improved. The fault diagnosis expert system module can actively conduct the maintenance when the performance of the switch cabinet is reduced to a certain degree or before the occurrence of a fault. Therefore, a reliable technology guarantee is provided for the safe, stable and high-quality operation of the device. The service life of the device is greatly prolonged.

Description

technical field [0001] The invention relates to the electric power industry, in particular to an intelligent control device for switch cabinets suitable for various switch cabinets such as high-voltage switch cabinets, handcart cabinets, fixed cabinets, and ring network cabinets. Background technique [0002] High-voltage electrical equipment is an important equipment in the power grid. Once an accident occurs, it will cause a partial or large area blackout. Therefore, these equipment must be inspected and maintained during operation after a period of operation. During normal operation, the conductive circuit of high-voltage electrical appliances generates heat energy through the working current for a long time, which makes the temperature of electrical materials rise. At this time, the temperature rise generally does not exceed the specified range, but once the conductive circuit has poor contact, the temperature will rise. Beyond the specified range, the mechanical strengt...
