传游锡堃再战新北 侯友宜：最强劲的对手是自己

摘要： 高压开关柜在运行过程中，柜内触点与母线连接处、动静触头电路发热过大，易引发停电和火灾事故。因此，高压开关柜内温度监测尤其是三相触点温度监测非常重要。高压设备存在裸露电压，传统的有线温度检测方法因无法完全解决高压绝缘问题而不能应用。无线测温系统采用无线电波进行信息传输，不需要布线，与高压设备等电势，不需要采取绝缘措施。因而无线测温系统可解决高压设备测温难题。

Abstract: During the operation of the high-voltage switchgears, The contact in the cabinet and the bus connection, the dynamic and static contact circuit generates too heat, which is easy to cause power failure and fire accident. Therefore, the temperature monitoring is very important in the high-voltage switch cabinet, especially the three-phase contact temperature monitoring. The traditional wired temperature measurement method can not be used because of the exposed voltage of high voltage equipment. The wireless temperature measurement system uses radio waves, no wiring, equal potential with high-voltage equipment, and no insulation measures. Therefore, the wireless temperature measurement system can solve the temperature measurement problem of high-voltage equipment.
