Advantages of film capacitors

Film capacitors are widely used in electronics, home appliances, telecommunications, electric power, electrified railways, hybrid vehicles, wind power, solar power, etc., and are used in bypass, DC blocking, coupling, decoupling, and pulse. , logic, timing, circuit oscillators, etc., thanks to its superior performance, then what is the superiority of film capacitors? Let's take a look.

1. Parallel film capacitor: also known as moving film capacitor. It is mainly used to compensate the reactive power of the inductive load of the power system to improve the power factor, improve the voltage quality and reduce the line loss.

2. Series film capacitors: connected in series in power frequency high-voltage transmission and distribution lines to compensate the distribution inductance of the line, improve the static and dynamic stability of the system, improve the voltage quality of the line, lengthen the power transmission distance and increase the transmission. ability.

3. Coupling film capacitors: mainly used for high-frequency communication, measurement, control, protection of high-voltage power lines and components used in devices for extracting electrical energy.

4. Circuit breaker film capacitor: formerly known as voltage equalizing capacitor. Parallel connection on the fracture of the high-voltage circuit breaker acts to make the voltage between the fractures uniform during the breaking process and disconnection, and can improve the arc-extinguishing characteristics of the circuit breaker and improve the breaking capacity.

5. Electrothermal film capacitor: used in electric heating equipment systems with a frequency of 40 ~ 24000 Hz to improve the power factor and improve the voltage or frequency of the circuit.

In general, film capacitors integrate advanced technologies such as modern measurement and control, power electronics, network communication, automation control, and power capacitors. The backward mechanical contactor that has fallen behind the traditional reactive power compensation device has changed the bulky and bulky structural mode of the conventional reactive power compensation device, so that the new generation of low-voltage reactive power compensation device has better compensation effect and smaller volume. The utility model has the advantages of lower power consumption, cheaper unit price, more cost saving, more flexible use, more convenient maintenance, longer service life and higher reliability, and adapts to the higher requirements of modern power grid for reactive power compensation.
