Abstract

The invention discloses a temperature monitoring device for a wireless and passive surface acoustic wave switch cabinet. The device comprises a sensor module, an acquisition and display module, and abackground detection module. The sensor module is composed of a plurality of SAW temperature sensors. The plurality of SAW temperature sensors are arranged at the to-be-measured temperature positionsof electric equipment in the switch cabinet. The acquisition and display module comprises an acquisition display and an antenna. The antenna is used for receiving electromagnetic wave signals transmitted from the SAW temperature sensors and transmitting the signals to the acquisition display. The acquisition display is used for converting electromagnetic wave signals into a temperature value, displaying the temperature value on a display screen, and sending the temperature value to the background detection module. The background detection module comprises a plurality of computers. The plurality of computers are used for displaying and storing temperature value data in real time. The acquisition display is connected with a serial port server through a 485 bus and then is connected with theplurality of computers respectively. According to the invention, the technical problems of a temperature measuring sensor, such as short service life and single function, are solved.

Description

technical field [0001] This application relates to the field of electric power, in particular, to a wireless passive surface acoustic wave switchgear temperature monitoring device. Background technique [0002] Conventional temperature measurement methods for substation electrical equipment include: temperature measurement wax sheet, thermocouple, thermal resistance, semiconductor temperature sensor, etc. These sensors are usually placed directly on the point to be measured. The temperature measurement wax chip is to check the melting degree of the wax chip through manual inspection, and judge and estimate the temperature of the point to be measured; other sensors use metal wires to transmit power and transmit signals, which belongs to the wired sensing method. [0003] For example, fiber optic temperature sensors use optical fibers to transmit temperature signals, which have excellent insulation properties and can isolate high voltages. The optical fiber temperature sensor...
