Cable head online temperature-monitoring apparatus

Abstract

The invention provides a cable head wireless temperature-monitoring apparatus, and belongs to the technical field of electric power. The technical problems to be solved of an electric energy parameter monitoring device are as follows: the conventional temperature-monitoring device has following defects: firstly, the installation is not easy, and the networking is inconvenient; secondly, the service lifetime of a battery is short, and power taking is difficult; and thirdly, data collection is not easy, and analysis is not facilitated. The technical scheme to solve the problems and main purposes are as follows: the wireless temperature-monitoring technology is employed; firstly, the installation is convenient, and watchband type installation is adopted; secondly, power supply with the battery is employed, the effective service lifetime can reach more than three years, and the problem of power supply of a wireless module is solved; and thirdly, the networking is convenient, and functions of data storage, inquiry, and statistics can be realized with cooperation of a host computer.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a power parameter monitoring device. Background technique [0002] Power plants, substation switch cabinets, bus connectors, outdoor knife switches and other important equipment. During the long-term operation, the contacts of the switch and the bus connection and other parts will generate heat due to excessive contact resistance due to aging, and the temperature of these heat-generating parts is difficult to monitor, which eventually leads to accidents. In recent years, many switch overheating accidents have occurred in power plants and substations, causing fires and large-scale power outages. Solving the problem of switch overheating is the key to eliminating such accidents. Realizing online temperature monitoring is an important means to ensure the safe operation of high-voltage equipment .

Problems solved by technology

[0003] In the existing temperature measurement technology, the wired temperature measurement device is inconvenient to install, and there is a requirement for the distance between the main controller and the temperature measurement point. For cable trenches and overhead lines, the temperature measurement module cannot be installed, only For the cable head in a certain switch cabinet, it is not conducive to centralized control

As for the infrared temperature measuring device, it can solve the problem that some wired temperature measuring devices are not easy to install, but if the main controller and the temperature measuring point are not in an effective space, it will not be able to measure, and the infrared device will be dusty after a long time Coverage affects the temperature measurement accuracy, and it is also inconvenient to install, which is also not conducive to centralized control
