style="text-indent:25px">并網(wǎng)柜故障的溫度原因：這種故障也較常見，斷路器標注的額定電流，是器件在溫度為30度情況下能長期通過的較大電流，溫度每升高10度電流減少5%。而斷路器因為有觸點存在，也是一個發(fā)熱源。造成斷路器溫度過高的原因有兩種：一是斷路器和電纜接觸不良，或斷路器本身觸點接觸不好，內(nèi)阻大，導(dǎo)致斷路器溫度升高;二是斷路器安裝的地方環(huán)境封閉散熱不好。判斷依據(jù)：斷路器動作時，用手去摸，感覺溫度偏高，或看到接線端子有溫度偏高，甚至有燒焦的氣味。解決方法：重新接線，或更換斷路器。河北并網(wǎng)柜銷售價格</p><p
