电网中众多高压电气设备本身和设备之间的连接点是电力输送最薄弱环节，这个薄弱环节的实质问题就是联接点发热。针对电气设备接点部位的材料老化、接触不良、电流过载等因素引起的温升过高的故障隐患，尤其是对于目前普遍使用的小车式开关柜，其断路器与开关柜之间采用插头连接，长期的大电流、触头老化等因素易致其接触电阻增大，从而造成触头温升过高导致连接点发热并形成恶性循环：温升、膨胀、收缩、氧化，电阻增大、再度升温直至甚至烧毁等现象酿成事故，保定国电中科电气公司开发了能够及时监测到电气接点温升的RCTM2-6无线温度在线监测系统。本产品采用低功耗设计、无线隔离等电位采集等高新技术，具有隔离彻底、安装方便、抗干扰能力强、工作可靠、等特点，能很好的解决高电压状态下的温度测量问题，为目前较理想无线方式的开关柜测温解决办法。具有界面可视化、声光报警、全隔离RS485通信接口功能。本产品可应用于开关柜静触头、隔离开关、电缆接头、母线接头、变压器接点等部位的温度监测，可在新设备上安装也可以在老设备上改造

Numerous high voltage electrical equipment in power grid connection between itself and the equipment is the most weak link in electricity transmission, the weak link in the essence of the problem is the connection point. For electrical equipment contact parts of the material factors such as aging, poor contact, current overload caused by high temperature rise of the problems, especially for the current widespread use of the car type switchgear cabinet, using plug connection between the circuit breaker and switch cabinets, long-term high current, contact aging factors, such as easy to cause the contact resistance increases, resulting in contact lead to join high fever and form a vicious circle: temperature, expansion, contraction, oxidation, resistance increases, the phenomenon such as heating up again until even burned into accidents, baoding guodian zhongke electric company developed can timely monitoring to the temperature rise of the electrical contact RCTM2-6 wireless temperature online monitoring system. This product USES low power design, isolate the potential acquisition and other high and new technology such as wireless, with isolation completely, easy installation, strong anti-interference ability, reliable operation, etc., can be a very good solve the problem of high voltage state of temperature measurement, as the ideal wireless way switch cabinet temperature measuring solution. Interface visualization, sound light alarm, full isolation RS485 communication interface function. This product can be used in the static contact of the switch, isolating switch, cable joint, busbar joints, transformer contact temperature monitoring, and other parts can be installed on new equipment can also be on the old equipment modification
