i.背景
使用开关柜时，人们都非常注重电力测温。开关柜温度过高主要由以下原因造成：
1.运输和工人安装不佳等原因引起触头接触不佳，接触电阻变大就会出现触头温度升高，进而可能烧毁停电。
2.长期运行过程中会出现表面氧化以及接头松动和老化的现象，这也是造成设备过热甚至出现严重事故的主要原因之一。
这些原因不可避免，由此开关柜温度监测非常重要。但是开关柜内空间狭小，传统的测温方式不能够满足需求，因为人工巡检监测不了。安科瑞无线测温系统成功解决这一问题，因为它是将温度传感器直接固定在易发热的部位上，然后通过无线传输的方式将数据传送到后台，并能够实现温报警的作用。
i.background
when using switch cabinets, people pay much attention to electrical temperature measurement. the switch cabinet temperature is too high mainly caused by the following reasons:
1)reasons such as poor transportation and installation by workers will cause poor contact of the contacts. the increase in contact resistance will cause thetemperature of the contacts to rise, which may burn out and power out.
2)surface oxidation, loosening and aging of joints will occur during long-term operation, which is also one of the main reasons for equipment overheating and even serious accidents.
these reasons are inevitable, so the temperature monitoring of the switch cabinet is very important.however, the space in the switchgear is small, and the traditional temperature measurement method cannot meet the demand because the manual inspection cannot be performed.acrelwireless temperature measurement system successfully solves this problem because it directly fixes the temperature sensor on the heat-prone parts, and then transmits the data to theserverthrough wireless transmission, and can realize the function of over-temperature alarm.
