Abstract

The invention relates to the field of safety monitoring of power distribution cabinets, in particular to a power distribution cabinet and an online temperature monitoring system thereof. A power distribution cabinet on-line temperature monitoring system comprises a background server and a power distribution cabinet, a low-power-consumption near-infrared chip, a temperature-sensitive probe and a controller are arranged in the power distribution cabinet, the low-power-consumption near-infrared chip excites the temperature-sensitive probe, the controller reads and stores data monitored by the temperature-sensitive probe, the controller is in communication connection with the background server, and the background server is in communication connection with the power distribution cabinet. The background server performs real-time online monitoring on the temperature in the power distribution cabinet; the temperature-sensitive probe is made of a rare earth doped fluoride material. The method is high in temperature detection accuracy, so that the method can be well applied to online temperature monitoring of the power distribution cabinet. And meanwhile, the near-infrared chip is adopted as an excitation source, so that the cost of the temperature measurement system is reduced.

Description

Technical field [0001] The present invention relates to the field of safety monitoring of the power distribution cabinet, in particular the distribution cabinet and its online temperature monitoring system. Background technique [0002] With the rapid development of science and technology, the demand for electric equipment is increasing. The power distribution cabinet is an important equipment for the power system. It can turn off the power line in time to prevent safety accidents caused by the line failure. It is simple and easy to operate. It is widely used in the switch station, the community distribution chamber, and the box substation. . The power distribution cabinet is generally operating in high voltage, large current and strong magnetic field environments, which causes the resistance to increase due to surface oxidation, corrosion, aging, etc. due to surface oxidation, corrosion, aging, etc., resulting in elevated local temperatures, and heat is constantly accumulating. ...
