电力系统中,各类设备的开断接触点,由于制造、环境污染、触点氧化、电弧冲击等原因造成接触电阻增大,在运行时往往不断发热,温度不断上升,给设备安全运行埋下隐患,如果不及时发现,容易导致起火或爆炸,造成大量财产损失。因此,电力设备的温度在线监测系统越来越得到大家的认可和重视。传统的红外、光纤及有源无线测温系统在安全性、适用性、稳定性、实时性等方面存在一定的技术缺陷。感应取电无源无线温度在线监测系统在高压电力设备上得到广泛应用,有效的解决了传统测温技术在安全性、可靠性、稳定性、实用性等方面存在的问题。
Power system, all kinds of equipment break contact point, due to manufacturing, environmental pollution, contact oxidation, arc impact caused by contact resistance increases, the operation is often constantly heating, the temperature rising, the safe operation of the equipment laid Hidden dangers, if not discovered in time, easily lead to fire or explosion, resulting in a lot of property damage. Therefore, the on-line temperature monitoring system of power equipment is getting more and more people’s recognition and attention. The traditional infrared, optical fiber and active wireless temperature measurement system have certain technical flaws in terms of safety, applicability, stability and real-time performance. Induction pick-up passive wireless temperature on-line monitoring system is widely used in high-voltage power equipment, which effectively solves the problems of safety, reliability, stability and practicability of the traditional temperature measurement technology.
