在濟南配電箱前面有一扇門。當(dāng)門打開時，配電箱內(nèi)的所有設(shè)備都暴露出來，便于維護。配電箱采用國產(chǎn)化設(shè)計，結(jié)構(gòu)緊湊，維修方便，線路方案組合靈活。配電箱配有空氣斷路器和熔斷器作為短路保護。還配備了接觸器和熱繼電器。箱子的前門可配備操作按鈕和指示燈。

　　配電柜分級

　　The distribution box represents the voltage of the bus. There is a door in front of the distribution box. When the door opens, all the equipment in the distribution box is exposed for easy maintenance. The distribution box adopts localization design, the structure is compact, the maintenance is convenient, and the combination of line scheme is flexible. The distribution box is equipped with air circuit breakers and fuses as short circuit protection. Contactors and thermal relays are also equipped. The front door of the box can be equipped with operation buttons and indicators.

　　(1)一等配電設(shè)備統(tǒng)稱為配電核心。它們集中安裝在企業(yè)變電站中，并將電能分配給不同地點的低級配電設(shè)備。這個級別的設(shè)備只取決于步驟，降壓變壓器的電氣參數(shù)較高，輸出電路容量也較大。

　　(1) such distribution equipment is collectively referred to as the distribution core. They are concentrated in enterprise substations and distribute electricity to low-level distribution equipment in different locations. This level of equipment only depends on the steps, the voltage transformer has higher electrical parameters, and the output circuit capacity is also large.

　　(2)二次配電設(shè)備是配電柜和電機控制核心的總稱。配電柜適用于負載分散、電路少的場合;在負載集中、電路多的情況下，采用電機控制核心。它們分配上層分布電路的電能。

　　(2) Secondary distribution equipment is the general name of distribution cabinet and motor control core. The distribution cabinet is suitable for the field station with scattered load and less circuits; in the case of concentrated load and many circuits, the motor control core is adopted. They distribute the electricity of the upper distribution circuit.

　　濟南配電箱這一水平的設(shè)備為工地企業(yè)提供保護，監(jiān)測和控制負荷。
