Abstract: With the development power industry,the requirements for the safety and reliability of equipment are getting higher and higher. In this situation,ACREL wireless temperature monitoring system is designed for high voltage device. This technology is to install the temperature sensor with built-in battery or temperature sensor by current sensing and wireless transmitter module at each temperature measurement point. The sensor periodically sends the temperature measurement data wireless to the receiving unit, and the receiving unit can be connected to the network to send the data to the master station, thereby realizing electrical temperature monitoring of a regional system.

This article introduce wireless monitoring system used in substations in Netherlands.

1.當(dāng)前現(xiàn)狀 Current Status

多年來(lái)，由于技術(shù)水平的限制，雖然曾利用紅外測(cè)溫儀、紅外成像儀、感溫電纜、傳統(tǒng)的點(diǎn)式測(cè)溫系統(tǒng)希望解決上述問(wèn)題，但都無(wú)法實(shí)現(xiàn)開(kāi)關(guān)柜內(nèi)如斷路器、刀閘聯(lián)接點(diǎn)和觸頭測(cè)溫。目前，國(guó)內(nèi)電力測(cè)溫主要應(yīng)用紅外點(diǎn)測(cè)儀和光纖測(cè)溫儀，而在線方式由于無(wú)法解決高壓絕緣問(wèn)題，所以高壓開(kāi)關(guān)的觸點(diǎn)等空間有限的電氣設(shè)備基本上都是處于*無(wú)監(jiān)控的狀態(tài)下運(yùn)行，存在重大安全隱患。

For many years, due to the limitations of the technical level, although infrared thermometer, infrared imager, temperature sensing cable, traditional point-type temperature measurement system have been used to solve the above problems, but can not achieve the switch cabinet such as circuit breaker, the connection point and contact temperature measurement. At present, domestic electric temperature measurement mainly uses infrared point measuring instrument and optical fiber temperature measuring instrument. However, the on-line method cannot solve the problem of high-voltage insulation, so the electrical equipment with limited space, such as the contact of high-voltage switch, basically operates in a completely unmonitored state, with major safety hazards.
