低压配电柜柜体结构,主柜体采用C型材或8MF开口型材,低压配电柜内钢板采用敷铝锌钢板,低压抽屉式配电柜体采用进口敷铝锌钢板,并要有足够的通风措施,确保散热良好。前面已为大家介绍过常见的几种低压配电柜型号,今天为大家介绍低压配电柜柜体内部的要求。
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.
低压配电柜柜体内部要求,柜体内应有防护装置,应提供挂锁或其他联络装置,并有操作手柄,手柄位置应表明断路器处于断开或合闸状态。主进线柜与母线联与段柜之间应互闭锁,并能过程控制。抽屉二次接线采用插入式结构,并且柜内设备机械配合和间隙应符合机械和电气距离上的要求,操作灵活可靠。

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.
另外所有操动机构和辅助开关的接线除有特殊要求外,同种控制原理的抽屉,均采用标准接线,以保证配电柜的同种属性的抽屉的可靠互换; 对于抽屉柜内电气联锁,控制回路的接线,应进行严格检查,以保证回路的接线正确性,完整性。柜内装有用于检查和维护的照明灯,照明灯行程开关与柜体的后门联锁,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.
