通过监测母线接点、高压电缆接头、高压开关触点温度的运行情况，可有效防止高压输、变电故障的发生，为实现安全生产提供有效保障。
因此采取有效措施监测高压母线及高压开关接触温度是电力系统急需解决的重大课题。
许多母线以及开关处于高电位，目前国内专门用于高压母线、高压开关及电接触发热测量的仪器还很少。
温度监测的方法，一种是在高压电接触表面涂一层颜色随温度变化的发光材料，通过观察其颜色变化来大致确定温度范围，这种方法准确度低、可靠性差，不能进行定量测量；另外一种方法是利用辐射特性的红外热像仪，准确度较高，但由于需要光学器件，在高压开关柜等特定场合使用不太方便，而且价格较高，推广应用有一定困难。
更重要的是以上两种方式都需要人工进行巡查，不能实时得到温度数据，所得到的数据永远是滞后的，起不到温度实时报警功能。
而有线通讯方式的电子仪表不符合电力高压环境测量仪表规范。
我公司自主研发的“电力工业无线温度监控系统”解决了目前存在的上述问题,可在高压环境下精确测量温度,准确有效地实现了实时监控。
该系统已通过华北电力大学、国家无线电检测中心、国家计算机检测中心、北京市技术监督局、西北电科院等相关部门的前期综合测试，并在内蒙古阿拉善电管局、陕西韩城电厂等单位进行了安装和现场运行测试，该系统完全符合高压环境仪表的要求，运行稳定,能在高压环境下准确及时处理数据、传输数据。

INTRODUCTION1.1 Safety InformationThis manual contains information that must be observed in the interest of your own safety and to avoid damage to assets. Please read this manual before installing and commissioning the device and keep the manual in an accessible location for all users.To satisfy FCC RF Exposure requirements for mobile and base station transmission devices, a separation distance of 20cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance operation at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.1.2 Hardware FeaturesThe IWTT range of Wireless Temperature Transmitters has been designed to measure the Temperature of the medium connected and transmit the value to one of the IWR range of receivers where the value can be outputted as either a 4-20mA or 1-5Vdc signal.The IWR-1 has a single output and the IWR-5 has five outputs, each of which can be linked to an IWTT transmitter.The IWTT temperature transmitter works on the licence-free 2.4 GHz band.Ranges of up to 500m are possible using the standard transmitter and receiver unit with the optional 3dBi antenna giving a range of up to 750m.The transmitter is powered by a 3.6V lithium cell and care must be taken to insert the battery in the correct polarity.2. UNPACKINGThe instrument should be carefully inspected for signs of damage which may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.3. PRODUCT IDENTIFICATION LABELThe unit delivered should be carefully inspected to ensure it is suitable for the application required. Detailed information on the product is included in the identification label and the user manual.Please ensure in particular, that the temperature range of the IWTT is suitable for the intended application and that the IWTT unit will not be subjected to temperatures and/or temperatures greater than those specified in this manual.4. INSTALLING/CHANGING THE BATTERYA Lithium 3.6V battery is included inside the IWTT transmitter. The battery may be changed at any time but the correct polarity must be observed at all times! After the battery has been changed, the unit should be switched on using SW3 pushbutton and then SW1 should be pushed for 5s.This is to ensure the battery life count is reset correctly when a new battery is installed.The internal LED will flash 5 times to indicate this procedure has been carried out successfully.The battery life is determined by the rate the transmitter sends the Temperature value to the receiver, this update rate can be selected using Dip Switch 1 and the default value is 10s.Please dispose of all batteries as specified by the legislator according to the Closed Substance Cycle and Waste Management Act or country regulations.5. SETTING UP THE IWTT WIRELESS TEMPERATURE TRANSMITTERThe IWTT instrument is shipped in a default configuration which allows the unit to connect with any default IWR receiver unit and transmit the measured temperature every10s simply by switching the unit on using SW3 on the internal circuit board.If a different update rate is required, or a different network frequency channel is required these parameters can be selected using DIP Switch 1 as detailed below:Switches 1, 2, 3 & 4 select the RF Network the IWTT will transmit on. The defaultnetwork for both the IWTT transmitter and IWR receiver is network 1.RF NETWORK 1 2 3 41 0 0 0 02 0 0 0 13 0 0 1 04 0 0 1 15 0 1 0 06 0 1 0 17 0 1 1 08 0 1 1 19 1 0 0 010 1 0 0 111 1 0 1 012 1 0 1 113 1 1 0 014 1 1 0 115 1 1 1 016 1 1 1 1Switches 5, 6 & 7 select the Transmission rate of the unit.

This is used with the 5 channel receiver unit (IWR-5) to select which Temperature transmitter is linked to which 4-20mA or 1-5Vdc output channel.Tx Channel Number 8 9 101 0 0 02 0 0 13 0 1 04 0 1 15 1 0 0The IWTT transmitter is now set up and ready to be used. Install the unit into the pipework as required and switch the unit ON using SW3. Pushbutton switch SW1 can be pushed to force the unit to transmit its current temperature and LED 1 will flash twice if the transmission has been received and acknowledged by an IWR receiver unit.If the unit has transmitted successfully the 4-20mA or 1-5Vdc output of the connected receiver unit will output a value reflecting the temperature level being measured.6. TROUBLE-SHOOTINGGUIDEProblem encountered Possible CausesLED1 doesn’t flash when pushbutton SW1 is pressed Unit not switched on, switch on using SW3. Battery not installed correctly.Battery needs replacing.LED1 only flashes once when SW1 is pressed IWR receiver not switched on.IWR receiver not set up for the same RF network.IWR receiver not within range of transmitter.If IWR-1 receiver is used, ensure that the transmitter is set to Tx Channel 1Output from IWR receiver isn’t equivalent to the Temperature being monitored IWR receiver set up incorrectly, see IWR user manual for further details.Check that the green external LED on the receiver is flashing when the transmitter pushbutton is pressed as receiver may be out of range.7.
