What is the difference between circuit breaker and air switch?
2019-11-14Circuit breaker brand products have a good arc-extinguishing ability, automatic trip in the case of short-circuit and high-current circuit; in high-voltage, high-current circuits, it is often used as an operating device for power failure, power transmission, switching on and off load .
What is Voltage Regulator Stabilizer for Household?
2019-11-06The function of the household voltage regulator is to stabilize the power supply voltage required by the large fluctuation and the unsuitable electrical equipment within its set value, so that various circuits or electrical equipment can work normally under the rated working voltage.
How do Voltage Regulator Stabilizer develop these years?
2019-11-06Stabilization is a product with the best comprehensive technical performance, highest reliability and lowest maintenance cost among various technical types of AC regulated power supplies.
The Work Principle of Refrigerator Protector
2019-09-15The refrigerator is a must-have household item in our home, and in order to protect the refrigerator, the refrigerator protector will appear. The following small series will introduce the principle and use of the refrigerator protector in detail.
How is Voltage Regulator Stabilizer working?
2019-09-02Since some electric appliances contain coil components, eddy currents that hinder current flow are generated at the initial stage of energization. The generation of eddy currents weakens the instantaneous voltage at the start of the electric appliance, resulting in slow start-up, and strengthens the instantaneous voltage generated after the disconnection, which may cause spark damage. Circuit. A voltage regulator is needed to protect the proper operation of the circuit. The voltage regulator is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, so that the position of the voltage brush of the voltage regulator changes. The output voltage is kept stable by automatically adjusting the turns ratio of the coil. The larger capacity regulator also works on the principle of voltage compensation.
What is surge protector?
2019-04-01The circuit often generates high operating overvoltages when struck by lightning and when switching on or off inductive loads or large loads. This transient overvoltage (or overcurrent) is called surge voltage (or surge current).
Some Questions about Inverter
2019-03-27Simply put, an inverter is an electronic device that converts low voltage (12 or 24 volts) direct current to 220 volts alternating current. Because we usually use 220 volt AC to be converted to DC, and the inverter has the opposite effect, hence the name.
What is an Inverter?
2019-03-27An inverter (Inverter-) popular speaking, the inverter is a direct current (DC) into an alternating current means (AC) of. It consists of an inverter bridge, control logic and filter circuit.
