开关柜无线测温技术使得电力系统已经在逐步向着网络化、自动化、可靠易用的方面发展。据统计,以往的电力系统发生事故原因中有相当一部分与过热问题有关,发电厂、变电站的高压开关柜在设备长期运行过程中,开关柜中的触点和母线排连接处等部位因老化或接触电阻过大而发热,这些发热部位的温度无法监测终导致火灾事故。
The wireless temperature measurement technology of switch cabinet makes the power system develop towards the network, automation and reliability. According to statistics, a considerable part of the previous power system accidents are related to overheating. During the long-term operation of the high-voltage switchgear in power plants and substations, the contacts and bus bar connections in the switchgear are heated due to aging or excessive contact resistance, and the temperature of these heated parts cannot be monitored, which eventually leads to fire accidents.
无线测温装置集一次回路模拟图、断路器位置、开关状态、接地刀闸位置、弹簧储能状态、高压带电显示及强制性闭锁、环境温度湿度LCD显示控制、触头温度监测、电参数监测、二次分合闸线包电压指示、防误提示、人体感应、远方/就地、分/合闸、RS485通讯等多项功能于一体。装置采用嵌入式方式,安装快速方便,用户选用时只需提供相应一次接线方案图及开关接点即可。此系统运行期间大幅度降低现场事故的发生,为各企业用户创造可观的价值。
Wireless temperature measuring device integrates primary circuit simulation diagram, breaker position, switch status, grounding switch position, spring energy storage status, high voltage live display and mandatory locking, environment temperature and humidity LCD display control, contact temperature monitoring, electrical parameter monitoring, secondary opening and closing line package voltage indication, error proof prompt, human body induction, remote / local, opening / closing, RS485 communication, etc Function in one. The device adopts embedded mode, which is fast and convenient for installation. When users select it, they only need to provide corresponding primary wiring scheme diagram and switch contact. During the operation of this system, the occurrence of accidents on site is greatly reduced, and considerable value is created for users of various enterprises.
