Abstract

The invention discloses a bus temperature grading warning device. The bus temperature grading warning device comprises a temperature detection module, a temperature sensor is disposed in the temperature detection module, an output end of the temperature detection module is connected with a comparison circuit, an output end of the comparison circuit is connected with an indicating lamp module via an amplification circuit, and an output end of the amplification circuit is connected with an alarm device; and an output end of the temperature detection module is further connected with a signal emitter, and the signal emitter is in communication with an intelligent terminal through a Zigbee data transmission unit. The device can visually reflect a bus temperature condition on a bus cabinet through signal lamps and the alarm device and also can check a temperature condition of a bus through the intelligent terminal, a result is visual and clear, the device helps on-site operation personal rapidly find a bus at over-high temperature, and a corresponding measure is taken; and the structure is simple, wiring and installation are convenient, and overall cost and power consumption are reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power monitoring equipment, and in particular relates to a hierarchical alarm device suitable for monitoring the temperature of a high-voltage bus. Background technique [0002] The busbar is the basis of the entire power system, so the current flowing through the busbar is relatively large. When the resistance of the busbar increases due to the aging of the connecting link material, pressure changes, and changes in the contact area, the temperature of the busbar also increases. If the temperature rise cannot be discovered by the staff in time, it will cause a major accident in the power supply system. High-voltage switchgear is an important equipment in power plants and substations. Every year, there are accidents caused by overheating at the busbar connection. Therefore, the safety and security of the busbar should be improved. Stability is of great significance to the entire power system. [...
