低压抽屉柜又称抽屉式开关柜具有较高的可靠性、和互换性，目前生产的开关柜，多数是抽屉式开关柜。它们适用于要求供电可靠性较高的工矿企业、高层建筑，作为集中控制的抽屉。今天带大家了解低压抽屉柜的结构原理。

Low voltage drawer cabinets, also known as drawer type switchgear, have high reliability and interchangeability. Currently, most of the switchgear produced is drawer type switchgear. They are suitable for industrial and mining enterprises and high-rise buildings that require high power supply reliability, as drawers for centralized control. Today, I will introduce you to the structural principles of low-voltage drawer cabinets.

　　低压抽屉柜电路原理图构成：

The schematic diagram of the low-voltage drawer cabinet consists of:

　　1、主电源电路一部分：便是开关电源到电机大电流量根据的途径。关键由隔离开关、接触器主接触点、热继器或综合保护器等电气元器件构成。

1. Part of the main power circuit: it is the path from the switching power supply to the motor for high electrical flow. The key is composed of electrical components such as isolation switches, main contact points of contactors, thermal relays or comprehensive protectors.

　　2、控制回路一部分：便是对主电源电路电流量接通、断开的操纵。由接触器的电磁线圈及辅助触点、汽车继电器的电磁线圈及接触点、热继器或综合保护器辅助触点、切换开关、按键、信号指示灯、速率电源开关、拉绳开关、跑偏开关等元器件构成。

2. A part of the control circuit is the manipulation of the current flow of the main power supply circuit to turn on and off. Composed of electromagnetic coils and auxiliary contacts of contactors, electromagnetic coils and contact points of automotive relays, auxiliary contacts of thermal relays or comprehensive protectors, switching switches, buttons, signal indicator lights, speed power switches, rope switches, deviation switches, and other components.
