低压抽屉柜电路原理图构成
Composition of circuit schematic diagram of low voltage drawer cabinet
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(FS)、接触器主接触点(KM)、热继器(FR)或综合保护器(KH)等电气元器件构成。
1. Part of the main power supply circuit: it is the way from the switching power supply to the large current flow of the motor. The key is composed of electrical components such as disconnector (FS), contactor main contact (km), thermal relay (FR) or integrated protector (KH).
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. Part of the control circuit: it is the operation of turning on and off the current of the main power circuit. It is composed of electromagnetic coil and auxiliary contact of contactor, electromagnetic coil and contact point of automobile relay, auxiliary contact of thermal relay or integrated protector, change-over switch, key, signal indicator, speed power switch, pull cord switch, deviation switch and other components.
MNS低压抽屉柜
MNS低压抽屉柜操作原理:
Operating principle of MNS low voltage drawer cabinet:
先抽屉柜推及时,抽屉柜上隔离开关实际操作摇杆转到实验部位,隔离开关不接通,电源开关SP1合闭,PS2断开,指示灯亮(HW),当场配电箱切换开关转到中控部位(R),KA1得电。
First, the drawer cabinet shall be pushed in time. The actual operating rocker of the isolating switch on the drawer cabinet shall be turned to the experimental position. The isolating switch is not connected, the power switch Sp1 is closed, PS2 is disconnected, the indicator light is on (HW), the switching switch of the distribution box on the spot shall be turned to the central control position (R), and KA1 shall be powered on.
KA1延时继电器接通,中控备妥,中控传出指令汽车继电器K1得电(一直得电),K1延时继电器合闭,接触器KM得电接通,接触器辅助触点接通,回复数据信号传到中控。
The KA1 time delay relay is connected, the central control is ready, the central control sends out a command that the automobile relay K1 is powered on (always powered on), the K1 time delay relay is closed, the contactor km is powered on, the contactor auxiliary contact is connected, and the reply data signal is transmitted to the central control.
进行实验运行工作中;中控传出终止指令,K1跳停断开,从而接触器跳停断开,进行停止工作。
During experimental operation; When the central control sends out the termination command, K1 trips and disconnects, so that the contactor trips and disconnects to stop working.
