一、產(chǎn)品簡介
【JD-JB1H】山東競道光電廠家以客戶為中心，品質(zhì)至上，共創(chuàng)共贏。輸電線積冰是指在低溫雨雪天氣條件下由于過冷水溫或冰晶不斷凝附在電線上造成的結(jié)冰現(xiàn)象。電線結(jié)冰對電網(wǎng)的運行有很大影響，當(dāng)積冰到一定程度會造成倒桿、倒塔、斷線等，導(dǎo)致電網(wǎng)損毀、電力輸送中斷，造成惡劣影響。鑒于電線積冰的巨大危害，在惡劣天氣下需要有人不停檢查線路，但在一些環(huán)境惡劣的地方，人員也無法巡檢，本產(chǎn)品就是為了解決這個問題。
本積冰傳感器采用微波檢測技術(shù)，基于微波信號對冰、水、空氣等不同物質(zhì)的反饋信息的區(qū)別實現(xiàn)對傳感器敏感區(qū)域的結(jié)冰信息的監(jiān)測，并根據(jù)信號的強(qiáng)弱以及傳感器區(qū)域結(jié)冰的分布信息進(jìn)行結(jié)冰厚度計算。本產(chǎn)品一般安裝于電線塔上，通過測量本傳感器上的積冰情況，即可對等判斷出當(dāng)前電線塔附近的電線積冰情況。
二、技術(shù)指標(biāo)
1、檢測分辨率:0.01mm
2、最大測量厚度:30.00mm
3、通訊方式:RS485
4、通訊協(xié)議:MobusRTU/自動發(fā)送
5、工作電壓:5VDC
6、工作溫度:-40℃～85℃
7、功率:<1W（融冰裝置15W）
8、防護(hù)等級:IP67
三、產(chǎn)品特點
1、能檢測積冰厚度、下雨等天氣狀態(tài)。
2、溫度檢測傳感器。
3、可定時主動傳出測量數(shù)據(jù),也可支持主從方式傳輸數(shù)據(jù)。
4、具有融冰功能，當(dāng)輸電線進(jìn)行融冰時，可同時給本傳感器發(fā)送融冰指令（融冰功能需要單獨供電12VDC,12W）。
5、每臺設(shè)備都有的編號，通訊時要帶有此編號，適用大規(guī)模監(jiān)測系統(tǒng)。
6、主要檢測項目
天氣狀態(tài)：有6種狀態(tài):干、冰、雨、積水、融化中、結(jié)冰中。只有處于冰時測冰厚才有效。
溫度檢測：有兩個測溫點，一個是測量電路板附近的溫度，另一個測量融冰加熱器溫度。
四、安裝方法
1、一般使用本傳感器時需配有太陽能發(fā)電系統(tǒng)，用于給本終端系統(tǒng)供電，如下圖圖1所示，此終端安裝于需要監(jiān)測線路中某個輸電線的電力塔上。
圖1安裝終端
2、終端上帶有數(shù)據(jù)遠(yuǎn)傳裝置，為了照顧偏遠(yuǎn)地區(qū)無線通訊一般使用當(dāng)?shù)氐?G移動通訊網(wǎng)絡(luò)，服務(wù)器和客戶端需用戶自己構(gòu)建，也可向我司購買軟件套裝或使用我司平臺。
五、融冰功能
融冰時加熱器并不是一直加熱，采用加熱10秒，停止加熱25秒，交替進(jìn)行，直到加熱器溫度到達(dá)50℃自動停止或用戶手動停止融冰，此時本次融冰過程才會結(jié)束。

冰厚傳感器 對于電力系統(tǒng)的穩(wěn)定運行具有重要意義。在冬季，電線和電線塔上容易形成積冰，這會導(dǎo)致電線重量增加、電塔受力不均等問題，嚴(yán)重時甚至?xí)?dǎo)致電線斷裂、電塔倒塌等事故。通過實時監(jiān)測電線積冰情況，可以及時采取預(yù)防措施，如增加融冰設(shè)備、調(diào)整電力負(fù)荷等，從而避免事故的發(fā)生。
輸電線路結(jié)冰傳感器是保障輸電線路安全運行的重要設(shè)備之一。它的實時監(jiān)測和報警功能能夠及時發(fā)現(xiàn)線路結(jié)冰情況，減少線路故障的發(fā)生。
