Abstract

The invention discloses a high-voltage cabinet busbar joint temperature and current monitoring and protecting system which comprises a monitoring unit, a control unit, a fire protection unit, an alarm unit, a base station and a centralized control center. The monitoring unit, the control unit, the base station and the centralized control center are sequentially connected. The monitoring unit comprises a temperature monitoring module and a current monitoring module. The control unit comprises an A/D converter and a single-chip microcomputer. The fire protection unit comprises an automatic fire extinguisher. The control unit is connected with the base station through an RS485. The base station is connected with the centralized control center through a wired optical fiber. According to the system, temperature and current information of a busbar joint in a high-voltage cabinet is monitored, the monitored temperature is compared with normal temperature through the control unit, smog information in the high-voltage cabinet is acquired, urgent repair is conducted when fire breaks out, the information is collected to the centralized control center, the temperature and the current of the high-voltage cabinet busbar joint are remotely monitored on line, power work quality is improved, and the probability and losses of accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of power system monitoring, in particular to a temperature and current monitoring and protection system for bus joints of a high-voltage cabinet. Background technique [0002] At present, as power transmission equipment, closed busway has been widely used in indoor substations, high-rise buildings and factory buildings in recent years to replace traditional cables for power distribution. At present, closed busway mainly includes 4 types: air-insulated type, densely insulated type, high-strength type and fireproof type busway. Due to the characteristics of the closed busbar's own structure, the temperature rise has a great influence on its working performance and reliability, especially the closed busbar joints. When the temperature of the bus duct itself rises to a certain limit value, it will accelerate the aging of the insulation, or even destroy the insulation, cause accidents, interrupt power supply, an...
