Universal switch is mainly used for rated voltage of AC380V/50Hz, rated current to 160A and DC220V and below the conversion of a variety of electrical control circuit, voltmeter, ammeter commutation measurement control, power distribution device line conversion and remote control. Universal switch can also be used to directly control the start, speed, and commutation of small-capacity motors. Next Xiaobian introduced the working principle and applicable scope of the universal switch.
Universal switch operating principle
According to the different types of switches, the methods of operation and working principle are very different. The current universal conversion switches are LW6 and LW5 series. The universal switch of LW5 series is divided into the following methods according to the handle: Positioning and self-resetting are two kinds of so-called self-resetting, when the handle is dialed in a certain direction of gear, the hand is released after the hand is released; the self-positioning is the handle to a certain position, can not be automatic The restoration, but set in this position. The LW6 series of universal switch is suitable for the circuit of 2.2KW and can be reversed.
Universal switch application
Although a universal conversion and control process of the universal switch, it also has its own power, as well as the scope of application. The main application scope of the universal transfer switch is rated voltage 380V, AC value is 50Hz, DC voltage is 220V or less, in the rated current 160A, this is the applicable range of the universal transfer switch. Because the terminals of the universal transfer switch are connected with more terminals, the control direction is also more. Basically, if a universal transfer switch is installed, the voltage and current of the home can be converted, and no other switches need to be configured.
Universal conversion switch wiring method
Because there are many kinds of switch, so here can not be introduced for everyone, on the conversion switch wiring method, take the automatic transfer switch as an example, for everyone to introduce the conversion switch wiring method. Automatic transfer switch has manual, automatic, bypass and stop four stalls, each stall corresponding to the wiring and wiring object is not the same, the face of the switch, divided into four aspects of the left and right, behind the switch panel This is where the wiring is done. The left and right sides and the top and bottom are divided into groups first, and the wiring is performed through the grouping of the lines. This requires one's own personal experiment to understand the mystery.
Universal switch technology features
The connection line of the universal transfer switch is more complicated, but its internal combined structure is relatively simple, and most of them are the operation mechanism, the electric shock, the shaft, the handle, the fixed point device, and the contact system, thereby contributing to a loop control circuit. The universal transfer switch is small in size and does not occupy too much space. Generally, it is concealed, but it has more functions, universal conversion, good insulation performance, flexible conversion operation, compact structure, and safety and reliability. Is the main technical characteristics of the universal switch, because the current universal switch, its more models, and the applicable universal switch, but also different current and voltage. Non-operators are generally not allowed to touch the universal switch.
Editor's summary: The working principle and scope of application of the universal transfer switch are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
