What is Shaanxi power capacitor, how to classify?

Power capacitors, capacitors used in power systems and electrical equipment. Any two metallic conductors separated by an insulating medium form a capacitor. The size of the capacitor capacitance is determined by its geometric size and the characteristics of the insulating medium between the two plates. When a capacitor is used at AC voltage, the capacity of the capacitor is often expressed in terms of its reactive power, in watts or kilowatts. Small series will introduce the classification, principle, installation, operation and maintenance of Shaanxi power capacitors in detail.

Shunt capacitor is a kind of reactive power compensation equipment, parallel line, its main function is to compensate the reactive power of the system, improve the power factor, so as to reduce the power loss, improve the voltage quality and equipment utilization.

Series capacitors are mainly used to compensate the reactance of power systems and are often used in high-voltage systems.

Shaanxi power capacitor installation classification

Power capacitors can be divided into indoor type and outdoor type according to the installation method; According to the rated voltage of its operation can be divided into low voltage and high voltage two categories; According to the number of phases, it can be divided into single-phase and three-phase two kinds, except for low-voltage shunt capacitors, the rest are single-phase; According to the shell material can be divided into metal shell, porcelain insulation shell, bakelite shell and so on.

According to the use can be divided into the following 8 kinds:

1) Parallel capacitor. Formerly known as phase-shifting 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 capacitor. In series in power frequency high-voltage transmission and distribution lines, it is used to compensate the distribution of line inductance, improve the static and dynamic stability of the system, improve the voltage quality of the line, lengthen the transmission distance and increase the transmission capacity.

3) Coupling capacitor. It is mainly used for high-frequency communication, measurement, control, protection of high voltage power lines and as a component in the device that extracts electric energy.

4) Circuit breaker capacitor. Formerly known as equalizing voltage Shaanxi power capacitor installation. The parallel operation can equalize the voltage on the breaker break, so that the voltage between the breaks is even during the breaking process and the breaking time, and can improve the arc extinguishing characteristic of the breaker and increase the breaking capacity.

5) Electric heating capacitor. It is used in the electric heating equipment system with a frequency of 40 ~ 24000 Hz to improve the power factor and improve the voltage or frequency characteristics of the loop.

6) Pulse capacitor. It mainly plays the role of energy storage, and is used as the basic energy storage elements such as impulse voltage generator, impulse current generator and oscillation circuit for circuit breaker test.

7) DC and filter capacitors. Used in high voltage direct current device and high voltage rectifier filter device.

8) Standard capacitors. Used in power frequency high voltage measurement dielectric loss circuit, as a standard capacitor or as a capacitive voltage divider for high voltage measurement.
