Voltage Stabilizer 220V, leakage protector, and air switch are three different devices used to protect electrical appliances in household electrical systems. Their respective functions and features are as follows:
Voltage Stabilizer 220V
Function:
Mainly used to stabilize voltage and ensure that the power supply voltage remains within a stable range. The voltage stabilizer can automatically adjust the voltage to prevent excessively high or low voltage from damaging electrical appliances.
Application:
Suitable for electrical appliances with high requirements for voltage stability, such as computers, televisions, refrigerators, etc.
Working principle:
Through the internal transformer and regulation circuit, the input voltage is adjusted to the preset output voltage range.
Leakage protector
Function:
Used to detect whether there is leakage in the circuit and protect people from electric shock. The leakage protector can quickly cut off the power supply to prevent leakage from harming people and electrical appliances.
Application:
Suitable for various electrical equipment and household circuits, especially in humid environments or areas with a large risk of leakage.
Working principle:
By detecting the current difference (ie leakage current), if the leakage current exceeds the set value, the device will quickly disconnect the power supply.
Air switch (circuit breaker)
Function:
used for overload protection and short circuit protection. When the current in the circuit exceeds the set value, the air switch automatically disconnects the circuit to prevent overheating of the wire and possible fire risks.
Application:
widely used in household and industrial electrical systems to protect circuits from damage caused by overload and short circuits.
Working principle:
sense current changes through internal electromagnetic devices or thermal protection devices, and automatically cut off the circuit when the current exceeds the set threshold.
Summary
Voltage stabilizer: focuses on voltage regulation and stabilization, protecting electrical appliances from voltage fluctuations.
Leakage protector: focuses on detecting and cutting off leakage, protecting personal safety, and preventing injuries caused by leakage.
Air switch: focuses on overload and short circuit protection, preventing circuit overheating and fire risks.
These devices can be used alone or in combination as needed to achieve more comprehensive electrical protection.
