First, the principle of switching
According to the different switch models, the mode is also different in terms of operation and working principle. The current switch has LW6 and LW5 series. The switch of LW5 series is divided into: self-positioning and Self-recovery type, the so-called self-resetting type, when the handle is turned to a certain direction, the handle is returned to the original position after the hand is released; the self-positioning is the handle is dialed to a certain position, and the automatic restoration cannot be performed. , but set in this position. The LW6 series of switches can be used in the 2.2KW circuit, which can be reversed.
Second, the role of the switch
No matter what kind of transfer switch, it has its advantages, and the switch is also the same. Do you know what the role of the switch is? Because the switch has more terminals in the circuit, so that it can easily control the circuit of the circuit, play a role of conversion and control, commonly used to control the current meter and voltmeter in the home, and Configured line switching, remote control, etc. In addition, the switch also has a function to control the speed, start and commutation of the motor.
Third, the scope of the switch
Although the switch is a versatile conversion and control process, it also has its own power and range of applications. The main application range of the switch is rated voltage 380V, AC value is 50Hz, DC voltage is 220V or less. In rated current 160A, this is the applicable range of the switch. Because there are more terminals on the line connected by the switch, the direction of the control is also relatively large. Basically, installing a switch can complete the conversion of voltage and current in the home without configuring other switches.
Fourth, the characteristics of the switch technology
The connection circuit of the switch is more complicated, but the internal structure of the switch is relatively simple, and most of them are operated by mechanism, electric shock, shaft, handle, pointing device and contact system, thus contributing to a loop control circuit. The switch is small in size and does not occupy too much space. Generally, it is concealed, but it has many functions, universal conversion, good insulation performance, flexible conversion operation, compact structure, safety and reliability, and these are The main technical features of the switch, because the current switch, its model is more, and the applicable switch also has different current and voltage. Non-operators are generally not allowed to touch the switch.
The above and some examples are about one of the control switches, that is, the multi-faceted information of the switch, including the explanation of the principle of action and the explanatory text of the scope of application, I hope to help everyone.
Glass tube liquid level gauge is a direct reading liquid level measuring instrument, which is suitable for the on-site detection of liquid position in general liquid storage equipment in the process of industrial production. It has simple structure and accurate measurement. It is a traditional on-site liquid level measuring tool. Generally used for direct detection. A needle valve is installed at both ends of the liquid level gauge. When the glass tube is broken due to an accident, the needle valve will automatically close under the pressure of the container to prevent the medium in the container from flowing out.
