Line contact place temperature measurement and warning device

Abstract

The invention relates to a line contact place temperature measurement and warning device, which comprises a temperature measurement device, a judgment device connected with the temperature measurementdevice and a communication device connected with the judgment device, wherein the temperature measurement device comprises a temperature sensor arranged at a line contact place, a temperature sensorarranged on an adjacent phase line and a temperature sensor for sensing environment temperature; the judgment device is a single chip microcomputer, the single chip microcomputer is in data connectionwith each temperature sensor, the single chip microcomputer is preset with a threshold for a temperature difference between the contact place and the adjacent phase and a threshold for a temperaturedifference between the contact place and the macroenvironment of the contact, the single chip microcomputer compares the actual temperature difference with the preset threshold, and if any temperaturedifference is larger than the preset threshold, the judgment device sends signals to a monitoring backstage or a mobile phone of a working personnel through the communication device for high temperature warning. Online and real-time monitoring on the line contact place is realized, and warning information is sent for warning when the inter-phase temperature difference and the temperature difference with the environment at the contact place are judged to exceed the thresholds.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a temperature measurement and alarm device at a line contact. Background technique [0002] At present, in the process of power production, transmission and use, overheating of contacts is one of the important causes of electrical accidents, which poses a great threat to the safety of power supply and use, which cannot be ignored. The heating of the line contacts will not only cause a large amount of power loss, but also seriously affect the normal operation of electrical equipment. In the slightest, the life of electrical equipment will be shortened due to excessive operating temperature; in severe cases, it will cause fires or electrical accidents, interrupting industrial and agricultural production and residents Living electricity, causing incalculable losses. [0003] Due to the problem of contact heating, in the past, it was usually inspected by human eyes or mobile...

AI Technical Summary

Problems solved by technology

The heating of the line contacts will not only cause a large amount of power loss, but also seriously affect the normal operation of electrical equipment. In the slightest, the life of electrical equipment will be shortened due to excessive operating temperature; in severe cases, it will cause fires or electrical accidents, interrupting industrial and agricultural production and residents Living electricity, causing immeasurable losses

[0003] Due to the problem of contact heating, in the past, it was usually inspected by human eyes or mobile inspections with the help of infrared thermometers. It was difficult to find heating defects, or they could not be found in time due to the inspection cycle, which often caused damage to the equipment or caused accidents.
