低壓配電柜柜體結(jié)構(gòu)，主柜體采用C型材或8MF開口型材，低壓配電柜內(nèi)鋼板采用敷鋁鋅鋼板，低壓抽屜式配電柜體采用進口敷鋁鋅鋼板，并要有足夠的通風措施，確保散熱良好。前面已為大家介紹過常見的幾種低壓配電柜型號,今天為大家介紹低壓配電柜柜體內(nèi)部的要求。

For the structure of low-voltage distribution cabinet, the main cabinet adopts C profile or 8MF open profile, the steel plate inside the low-voltage distribution cabinet adopts aluminum zinc coated steel plate, and the low-voltage drawer type distribution cabinet adopts imported aluminum zinc coated steel plate, with sufficient ventilation measures to ensure good heat dissipation. We have introduced several common models of low-voltage distribution cabinet. Today, we will introduce the internal requirements of low-voltage distribution cabinet.

低壓配電柜柜體內(nèi)部要求，柜體內(nèi)應有防護裝置，應提供掛鎖或其他聯(lián)絡裝置，并有操作手柄，手柄位置應表明斷路器處于斷開或合閘狀態(tài)。主進線柜與母線聯(lián)與段柜之間應互閉鎖，并能過程控制。抽屜二次接線采用插入式結(jié)構(gòu)，并且柜內(nèi)設(shè)備機械配合和間隙應符合機械和電氣距離上的要求，操作靈活可靠。
                       

According to the internal requirements of low-voltage distribution cabinet, there shall be protection device in the cabinet, padlock or other contact device shall be provided, and operating handle shall be provided. The position of handle shall indicate that the circuit breaker is in open or closed state. The main incoming cabinet, bus coupler and section cabinet shall be mutually locked and process controlled. The drawer secondary wiring adopts plug-in structure, and the mechanical coordination and clearance of the equipment in the cabinet should meet the requirements of mechanical and electrical distance, and the operation is flexible and reliable.

另外所有操動機構(gòu)和輔助開關(guān)的接線除有特殊要求外，同種控制原理的抽屜,均采用標準接線，以保證配電柜的同種屬性的抽屜的可靠互換； 對于抽屜柜內(nèi)電氣聯(lián)鎖，控制回路的接線，應進行嚴格檢查，以保證回路的接線正確性，完整性。柜內(nèi)裝有用于檢查和維護的照明燈,照明燈行程開關(guān)與柜體的后門聯(lián)鎖,控制照明的投入或切除。

In addition, in addition to special requirements for wiring of all operating mechanisms and auxiliary switches, standard wiring is adopted for drawers with the same control principle, so as to ensure reliable exchange of drawers with the same attributes of distribution cabinet; For the electrical interlocking in the drawer cabinet, the wiring of the control circuit should be strictly checked to ensure the correctness and integrity of the circuit wiring. The cabinet is equipped with a lamp for inspection and maintenance. The travel switch of the lamp is interlocked with the back door of the cabinet to control the lighting on or off.
