High-voltage power temperature measuring system

Abstract

A high-voltage electric temperature measurement system includes an infrared temperature measurement probe and a non-contact infrared temperature measurement sensor; the infrared temperature measurement probe collects data and is connected to a non-contact infrared temperature measurement sensor, and one end of the non-contact infrared temperature measurement sensor is connected to a The wireless temperature measurement transmitter module, the non-contact infrared temperature measurement sensor transmits the monitored temperature signal through the wireless temperature measurement transmitter module, and the non-contact infrared temperature measurement sensor and the wireless temperature measurement transmitter module are connected together through a connection belt, And realize the installation of the temperature sensor. The present invention can measure, monitor, and statistically analyze the operating conditions of the contact temperature in the high-voltage switch cabinet and the cable branch box, and the staff can grasp the working conditions of the closed cabinet or the high-voltage contact to avoid failures.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a high-voltage electric temperature measuring system. Background technique [0002] Under the condition of high voltage and high current, the working reliability of the high voltage switchgear is closely related to the temperature rise of the isolating switch contacts. During the operation of the power grid, mechanical vibration, contact ablation and other reasons can deteriorate the contact conditions, increase the contact resistance, cause the temperature of the contact point to rise, aggravate the oxidation of the contact surface, and cause arc discharge at the local welding or loose contact , Eventually causing damage to electrical equipment or even power outages or fires and other major accidents. On the one hand, this kind of contact overheating fault accident comes from the quality problem of the high-voltage cabinet switch itself, and the more ...

Problems solved by technology

During the operation of the power grid, mechanical vibration, contact ablation and other reasons can deteriorate the contact conditions, increase the contact resistance, cause the temperature of the contact point to rise, aggravate the oxidation of the contact surface, and cause arc discharge at the local welding or loose contact , eventually causing damage to electrical equipment or even power outages or major accidents such as fires

On the one hand, this kind of contact overheating fault accident comes from the quality problem of the high-voltage cabinet switch itself, and the more important reason is that there is currently a lack of effective monitoring methods for the temperature rise of the isolating switch contacts
