Distribution type infrared online temperature measurement system for electric terminals of high-voltage equipment

Abstract

The invention belongs to the technical filed of temperature measurement, particularly relates to a distribution type infrared online temperature measurement system for electric terminals of high-voltage equipment, and comprises a temperature sensing module, a base station and a remote control terminal. The temperature sensing module is used for monitoring temperature information at a set temperature monitoring point and transmitting a temperature signal and / or an alarming signal to the base station through a wireless network. The base station is used for receiving the temperature signal and / or the alarming signal and transmitting the temperature signal and / or the alarming signal to the remote control terminal through a wired network or the wireless network. The remote control terminal is used for enabling management staffs to check operation conditions of the whole temperature measurement system in real time and to configure operation parameters of the temperature measurement system in real time. The temperature measurement system can achieve full-automatic online temperature monitoring of the electric terminals, achieves insulation between a temperature measurement element and a high-voltage line through a non-contact type temperature measurement mode, and ensures reliable operation.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement, and in particular relates to a distributed infrared online temperature measurement system for electrical contacts of high-voltage equipment. Background technique [0002] In recent years, the power transmission and transformation network of the power system has developed towards the direction of high voltage and large capacity, and the power load has shown a trend of rapid growth. With the continuous improvement of power customers' requirements for the safety, reliability and continuity of power supply, the phenomenon of overload operation of primary power equipment, over-period maintenance and even failure to power outage maintenance occurs from time to time, resulting in equipment being burned out or even A major fire accident occurred, which led to a power outage of the system, seriously endangering the safety of the power grid, and causing major economic losses to both the pow...

Problems solved by technology

[0003] At present, the commonly used online temperature measurement methods for electrical contacts mainly include temperature-sensing optical cables and thermistors. Among them, the temperature-sensing optical cable temperature measurement method mainly measures the temperature of cables laid in trenches or tunnels and their joints, which is difficult to use for contact comparison. On-line temperature monitoring of power distribution and transformation high-voltage equipment with multiple, complex distribution, and difficult wiring; although the thermistor temperature measurement method can be used for contact temperature measurement of high-voltage equipment, because the thermistor sensor used in it needs to directly contact high-voltage Equipment, so it is easy to be broken down by high-voltage arc during work, resulting in difficulties in use and maintenance

[0004] Other temperature measurement devices, such as temperature measurement systems using wax sheets, temperature test stickers, artificial far-infrared imaging, etc., usually have a low degree of automation, and cannot monitor the temperature of equipment in real time online, let alone summarize, analyze and warn of temperature changes. making it more difficult to meet people's needs
