Under the current rapid increase of electricity load, during the long-term operation of 35kV to 110kV switchgear, the temperature of the switch contacts, busbar connection parts, etc. will increase abnormally due to aging or excessive contact resistance. Finding and performing maintenance will cause serious equipment accidents. Solving the problem of overheating of the switch is the key to prevent such accidents. Real-time temperature monitoring is an important means to ensure the safe operation of high-voltage equipment. ，结合电力自动化行业检测、在线监测及保护配置相关规程，经过广泛的市场调研（与国内多家发电厂生产部门技术骨干交流和讨论），并综合现场实际运行工况，自主研发出具有技术先进、适用性强、高可靠性的无线测温 系统。 ZK1310 wireless temperature measurement system is our company's own resources , combined with the relevant regulations of the power automation industry inspection, online monitoring and protection configuration, after extensive market research (exchanges and discussions with the technical backbone of the production departments of many domestic power plants), and comprehensive field Under actual operating conditions, a wireless temperature measurement system with advanced technology, strong applicability and high reliability has been independently developed . It is a set of low power consumption and high reliability wireless temperature real-time monitoring system specially developed to solve the temperature rise of high voltage power equipment. The system has the characteristics of complete isolation, convenient installation, strong anti-interference ability, reliable operation, etc., and can well solve the problem of temperature measurement under high voltage conditions. 由我公司自主开发和研制的中央处理单元即无线测温接收模块装置（ 1只）、无线测温传感器即无线测温发送模块（1~9个，可扩展）组成。 The ZK1310 wireless temperature measurement system consists of a central processing unit independently developed and developed by our company, namely a wireless temperature measurement receiving module device ( 1), and a wireless temperature measurement sensor, namely a wireless temperature measurement transmission module (1 to 9, expandable).
