What are the functions of low-voltage electrical appliances?

Low-voltage electrical appliances exist relative to high-voltage electrical appliances. At present, there are many people who need to use low-voltage electrical appliances, and what are low-voltage electrical appliances? Although the voltage of low-voltage electrical appliances is not high, the use of them is also dangerous. When using low-voltage electrical appliances, Should you be able to pay attention to safety, and what are the functions of low-voltage electrical appliances?

1. What is low voltage electrical appliance?

A low-voltage electrical appliance is a component or device that can manually or automatically turn the circuit on or off according to external signals and requirements to switch, control, protect, detect, change and adjust the circuit or non-electrical object. According to the working voltage of the control electric appliance, it is divided into two categories: high-voltage control electric appliance and low-voltage control electric appliance, which are bounded by DC 1500V and AC 1000V.

In general, low-voltage electrical appliances can be divided into two major categories of distribution electrical appliances and control electrical appliances, and are the basic components of complete electrical equipment. In the agricultural, industrial, transportation, defense, and people's electricity sectors, most use low-voltage power supply, so the quality of electrical components will directly affect the reliability of low-voltage power supply systems.

Second, what are the functions of low-voltage electrical appliances?

The low-voltage electrical appliance can automatically or manually change the state and parameters of the circuit according to the requirements of the operation signal or the external field signal, and realize the control, indication, measurement, protection and adjustment of the circuit or the controlled object. The role of low-voltage electrical appliances is:

(1) Control function If the elevator moves up and down, fast and slow speed automatic switching and automatic stop layer.

(2) Protection function According to the characteristics of the equipment, the equipment, the environment and the human body can be automatically protected, such as overheat protection of the motor, short circuit protection of the power grid, and leakage protection.

(3) Measurement function Use the instrument and its corresponding electrical equipment to measure equipment, power grid or other non-electrical parameters, such as voltage, current, power, speed, temperature, humidity, etc.

(4) Regulation function Low-voltage electrical appliances can adjust some electric and non-electrical quantities to meet the needs of users, such as adjustment of diesel engine throttle, adjustment of room temperature and humidity, and automatic adjustment of illumination.

(5) Indication function The function of control and protection of low-voltage electrical appliances is used to detect the operating conditions of the equipment and the working conditions of the electrical circuit, such as insulation monitoring and protection of card-off instructions.

(6) Conversion function Switch between the power equipment or the low-voltage electrical equipment and control circuit to realize the function switching, such as the manual and automatic conversion of the excitation device, the switching of the power supply and the self-supplied power.

What is low-voltage electrical appliances? Low-voltage electrical appliances are generally referred to as one type of electrical appliances. They are not specific to a certain type of electrical appliances. Everyone should have a certain understanding of this type of electrical appliances. What are the functions of low-voltage electrical appliances? The role of each low-voltage electrical appliance will be different. It is recommended that you look at different products when using low-voltage electrical appliances.
