Existing thermometric mode mainly comprises wireless temperature measurement, optical fiber temperature-measurement and infrared measurement of temperature.Fibre optic temperature sensor adopts fiber optic transmission temperature signal, light transmitting fiber has excellent insulating property, can high pressure in isolating switch cabinet, therefore fibre optic temperature sensor can directly be installed on the high-voltage contact in switch cubicle, the running temperature of Measurement accuracy high-voltage contact, realizes the on-line monitoring of switch cubicle contact running temperature.But the optical fiber surface for isolated high-voltage may be polluted, and will cause optical fiber creeping discharge.This makes optical fiber temperature measurement system be restricted for the temperature measuring application of outdoor switch equipment.
Wireless temperature measurement adopts electromagnetic transmission signal, and sensor is directly installed on high-tension apparatus, and temperature survey is accurate, and can solve electric insulation problem, the feature of wireless temperature measurement is the impact of not climate environment, can measure the temperature of cubicle switch and bus contact joint.
Infrared measurement of temperature is contactless temperature-measuring, be subject to environment and the interference of electromagnetic field around, space in addition in switch cubicle is very narrow and small, (cannot must keep certain safe distance with testee because of probe by installation infrared temperature probe, and need just to the surface of testee), and wireless temperature measurement system is not by the restriction of switch cabinet structure.
Therefore, wireless temperature measurement opposed optical fibers thermometric and infrared measurement of temperature have certain advantage in thermometric.
