Meanwhile, in some areas with heavy load, the problem that the temperature rise of the switch cabinet exceeds the standard can exist. The temperature rise of the switch cabinet exceeds the standard, the safe and stable operation of equipment is directly influenced, moreover, the overheating problem is a constantly developed process, if the overheating problem is not controlled, the overheating degree is constantly intensified, and the performance of an insulating part and the service life of the equipment are greatly influenced. Because the point of generating heat is in sealed cabinet, the cabinet door of operation forbids opening, and the personnel on duty can't discover the defect of generating heat through normal means of surveing. When the heating is serious, the joint can turn red and even be fused, and the production accident is directly caused. According to statistics, a considerable part of the accident causes of the power system are related to the overheating problem, so that the effective measures are taken to monitor the temperature of the contact and the joint of the high-voltage switch, the high-voltage bus and the high-voltage cable, which is a problem to be solved by the power system. In order to monitor the heating condition of each part in the switch cabinet in real time, guarantee the normal operation of equipment, reduce the accident rate, need to transform the switch cabinet urgently, install temperature measuring device additional. Due to the development of the sensing technology and the micro-processing technology, the continuous state detection can be carried out on the running power equipment, the information of the equipment state change is measured at any time, the insulation state is diagnosed after the analysis and the processing are carried out, the maintenance scheme is determined according to the diagnosis result, and the targeted maintenance, namely the state maintenance, is realized.
The temperature measuring methods used in the high-voltage switch equipment at present include infrared temperature measurement, thermal resistance thermocouple temperature measurement, optical fiber temperature measurement and surface acoustic wave device temperature measurement. The infrared temperature sensor's that the cubical switchboard used reliability is lower, easily receives the influence of outside various factors, and the space in the cubical switchboard is very narrow and small in addition, is difficult to install infrared temperature probe (because the probe must keep certain safe distance with the testee to need just to the surface of testee), and the distance and the measurement angle of testee all have more strict requirements, and the structure is complicated, and is bulky, is unfavorable for the installation and promotes. Measuring the temperature of a thermal resistor and a thermocouple: metal wires are required to transmit signals, and the insulation problem cannot be solved, so that the metal wires cannot be applied to high-voltage switch equipment. Optical fiber temperature measurement: the surface of the electrical contact is pasted with an optical fiber temperature sensor which is connected to an optical fiber demodulator arranged in the cabinet body through an optical cable, and the optical fiber demodulator outputs corresponding temperature data. The optical fiber has the defects of easy folding, easy breaking and no high temperature resistance, and has larger wiring difficulty in the cabinet, higher manufacturing cost and difficult construction and maintenance. Measuring the temperature of the surface acoustic wave device: a high-power energy transmitting device is required to be arranged in a cabinet body to supply power to the surface acoustic wave device, and transmitted wireless signals have the problems of crosstalk and easy loss. The traditional current sensor only has a single temperature parameter, and cannot judge whether the temperature rise is caused by short-circuit fault or load increase.
