Problems solved by technology
Optical fiber temperature measurement technology has good electrical insulation and is free from electromagnetic field interference. It is especially suitable for harsh environments such as high voltage, high current, strong magnetic field noise, and strong radiation. It also has the characteristics of high sensitivity, high precision, and high speed. Optical fiber is easy to break, easy to break, not resistant to high temperature
After the accumulation of dust, it is easy to reduce the insulation, and the technical requirements of optical fiber are high, the system structure is complicated, the wiring is difficult, and the cost is high
[0008] The traditional monitoring method is to periodically monitor and record the temperature of the isolating switch, which requires the use of personnel and equipment, and can only be periodically tested intermittently, and there are many defects

The invention discloses a temperature monitoring device and an implementation method for an outdoor high-pressure switch. The temperature monitoring device is composed of a data monitoring center, a liquid crystal display instrument and a temperature collecting module. The data monitoring center is connected with the liquid crystal display instrument through a 485 bus, the liquid crystal display instrument is connected into the temperature collecting module in a wireless communication mode, and the temperature collecting module is directly connected with a temperature measuring mode. The implementation method includes the steps that the temperature collecting module collects the temperature of the temperature measuring point and transmits the temperature to the liquid crystal display instrument in a wireless mode through a wireless transceiving chip after the temperature is processed through an MSP430 microprocessor, the temperature is processed by an ARM processor in the liquid crystal display instrument and then transmitted to the data monitoring center through the 485 bus to be monitored, and a power source is provided for the temperature collecting module through a battery or an induction coil.
Description
technical field [0001] The invention relates to the field of monitoring the operating state of high-voltage power equipment, in particular to an online temperature monitoring device and implementation method of high-voltage power equipment. Background technique [0002] In the power system, the isolating switch is widely used in the connection of the transmission and distribution lines and the bus connection of the substation of the power plant. It can not only make the power grid run in sections, but also isolate faults for easy maintenance. In the power transmission operation of the line, the isolating switch is the only disconnection point and connection point that can be clearly seen and easily confirmed. [0003] The isolating switch is composed of moving contacts, static contacts and double saving blades. Due to long-term exposure of the isolating switch outdoors, aging, fatigue and corrosion of the spring cause the pressure of the contact point to decrease and other ...
