  • Detail

The universal change-over switch is a master electrical appliance with multi gear and multi loop control. The universal transfer switch is mainly used for the conversion of various control circuits, the commutation measurement control of voltmeters and ammeters, the conversion and remote control of distribution device circuits, etc. The universal change-over switch can also be used to directly control the starting, speed regulation and commutation of small capacity motors

universal transfer switch is mainly used for the conversion of various electrical control lines with rated working voltage of ac380v/50hz, rated current of 160A and dc220v and below, the commutation measurement control of voltmeter and ammeter, the line conversion and remote control of power distribution device, etc. The universal change-over switch can also be used to directly control the starting, speed regulation and commutation of small capacity motors. Next, I will introduce the working principle and scope of application of universal transfer switch

working principle of universal change-over switch

according to the different models of various switches, their modes of operation and working principle are also very different. At present, the universal change-over switch has LW6 and lw5 series. The universal change-over switch of lw5 series is divided into two types according to the mode of handle: self positioning and self resetting. The so-called self resetting is that when the handle is turned to a certain direction gear, after the hand is released, The handle returns to its original position; Self positioning is that the handle is turned to a certain position, which cannot be automatically restored, but is set at this position. The LW6 series universal transfer switch is suitable for circuits below 2.2kW and can be operated in reverse

application scope of universal transfer switch

although universal transfer switch is a universal conversion and control process, it also has its own power and application scope. The main scope of application of the universal change-over switch is the rated voltage of 380V, the AC value of 50Hz, and the DC voltage below 220V. In the rated current of 160A, this is the scope of application of the universal change-over switch. Because there are many terminals of the line connected to the universal change-over switch, there are also many control directions. Basically, installing a universal change-over switch can complete the conversion of voltage and current at home without configuring other switches

wiring method of universal transfer switch

because there are many kinds of transfer switches, we can't introduce them one by one here. About the wiring method of transfer switch, take the automatic transfer switch as an example to introduce the wiring method of transfer switch. The automatic transfer switch has four gears: manual, automatic, bypass and stop. The wiring mode and objects corresponding to each gear are different. Facing the switch, it is divided into four aspects: left, right, up and down. The wiring place is behind the switch panel. First, the left, right, up and down are divided into groups, and wiring is carried out through the grouping method of lines. This requires your own personal experiment to understand the mystery

technical characteristics of universal change-over switch

the connection line of universal change-over switch is relatively complex, but its internal combined structure is relatively simple, most of which are composed of operating mechanism, electric shock, rotating shaft, handle, pointing device and contact system, so as to promote a loop control circuit. The universal change-over switch is small in size and does not occupy too much space. It is generally installed in a concealed manner, but it has many functions, universal change-over, good insulation performance, flexible change-over operation, compact structure, safety and reliability. These are the main technical features of the universal change-over switch, because the current universal change-over switch has many models, and the applicable universal change-over switch also has different current and voltage. Non operators are generally not allowed to touch the universal transfer switch

editor's summary: This is the introduction of the working principle and scope of application of the universal transfer switch. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
