Non-contact insulation shielding monitoring device and method

Abstract

The invention discloses a non-contact insulation shielding monitoring device and method, and the device comprises a first housing, a second housing and a rotating assembly, and the first housing and the second housing jointly define a monitoring cavity for accommodating a T-connection position of a drainage cable; the first shell is provided with a monitoring system, the monitoring system comprises a temperature monitoring unit and a non-contact current monitoring unit, the first shell is internally provided with a mounting cavity, and the mounting cavity is provided with a first mounting position and a second mounting position; the temperature monitoring unit is used for measuring the temperature of the drainage cable, and the non-contact current monitoring unit is used for measuring the current of the drainage cable. According to the non-contact insulation shielding monitoring device and method provided by the technical scheme, the device is installed at the T connection position of the drainage cable, the branch current state of the drainage cable and the heating condition of the T connection position can be monitored in real time, and the problem that temperature and current measurement needs to be carried out at a short distance in a manual mode in a distribution network on-load operation project is solved. The working efficiency is low; and the operation risk is high.

Description

technical field [0001] The invention relates to the technical field of distribution network live equipment, in particular to a non-contact insulation shielding monitoring device and method. Background technique [0002] In recent years, with the rapid development of my country's economy and society, users' requirements for power quality are increasing day by day. The operation mode of power outage maintenance for distribution network equipment in the power supply system has formed a big contradiction with the continuous electricity demand of users. In order to In order to improve the quality of power supply service, power supply enterprises continue to optimize the maintenance methods of distribution network. Therefore, the live operation method of distribution network has been widely used in recent years. The maintenance of the power supply equipment of the distribution network system is a normal work, and the maintenance of the power supply equipment often means that the eq...

Problems solved by technology

[0005] The purpose of the present invention is to propose a non-contact insulation shielding monitoring device and method, which can be installed at the T junction of the drainage cable to monitor the current state of the branch current of the drainage cable and the heating situation at the T junction in real time, so as to solve the problem in the distribution network belt. In the load operation project, it is necessary to rely on manual methods to measure temperature and flow at close range, resulting in technical problems of low work efficiency and high operation risk. The structure is simple, the installation is convenient, and the performance is reliable.
