盤式剎車在配電箱中的部位應與環路和下列要安裝的卡盒相對性應，并標出電源電路名字。配電箱內的溝通交流、DC或不一樣額定電壓的開關電源應清晰標出。高壓配電柜上安裝的各種各樣閘刀開關和控制開關。當處在引路情況時，葉子的主題活動一部分不可電池充電(特殊情況以外)。配電箱上的小母線槽應是淡黃色(L1相)、翠綠色(L2相)、鮮紅色(L3相)、淡藍色(N零線)等色調，黃綠色兩色線為保護區線。日月明配電箱廠家提示配電(dian)箱(xiang)上(shang)的(de)電(dian)器設(she)備和儀表(biao)盤應(ying)堅固、齊整(zheng)、勻(yun)稱。

小型繼電器的基本原理是將一個鍵入數據信號變為好幾個輸出數據信號或將數據信號變大（即擴大汽車繼電器斷路器容積）的汽車繼電器。其本質是電壓繼電器，但它的斷路器較多（可高達8對）、斷路器容積達到5-10A、姿勢靈巧。當別的家用電器的斷路器多數不足時，高壓配電柜可(ke)依靠(kao)小型繼電器來拓展(zhan)(zhan)她們的斷(duan)路器多數，也是有根據(ju)小型繼電器完成(cheng)觸電事故插電容(rong)積的拓展(zhan)(zhan)。
