HV Shunt Capacitor
1． Application
HV shunt capacitor is applied in power frequency power system above 1kV in order to increase power factor of the system, improve voltage quality and reduce line losses.
2． Service environment
Normal service conditions
Installation site: indoor, outdoor, plateau, dump and hot , foal land, etc.
Ambient temperature：-40~+45℃
3． Model coding
4． Structure
Capacitor consistsof enclosure and core. Enclosure is made of full automatic welding stainlesssteel plates, and is welded high-strength hydraulic type bushings on the upper cover. The capacitor is filled with high-isolation electrical liquid medium of C101 type from France inside.
Core is made up bycomponents and insulation. The solid medium of components selects doublecoarsening polypropylene film from Finland, polar plate uses ultrathin aluminumfoil, the structure of folding and protuberant foil improves partial dischargelevel.
Some high-capacity products can be equipped with internal fuses; the new structure of internalfuses makes the products more reliable.
The products with internal discharge resistor adopts high quality HV glass glaze resistor to decrease the residual voltage of capacitor from√2Un to below 50V within 5min after switch off.

- Q: Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
- 0.45 capacitor used in the voltage level is high (for example, the transformer low voltage side voltage may reach 415V), with a tuned reactor (tuning reactor will increase the capacitor terminal voltage) situation; Note that the actual capacity of 0.45 capacitor nominal capacity (Actual voltage / 0.45) ^ 2 times;
- Q: What kind of capacitance can be divided into?
- The paper dielectric is made of two pieces of metal foil, made of very thin capacitor paper, rolled into a cylindrical or flat cylindrical core, and then sealed in a metal shell or insulating material (such as paint, ceramics, glass glaze, etc.) production. It is characterized by a smaller size, capacity can be done bigger. But there are inherent inductors and losses are relatively large, suitable for low frequency.
- Q: What is the principle of capacitance isolation?
- When the capacitor is connected to the AC circuit, there is also a charging process in which the charge is stopped when the capacitor voltage is equal to the supply voltage, and then the power supply voltage drops and the capacitor begins to discharge.
- Q: What is the difference between the power capacitor and the complement?
- Input compensation: three-phase co-fill capacitor input, the three groups of capacitors at the same time. The sub-capacitor can be put into operation separately.
- Q: How to judge the capacitor is good or bad?
- Multimeter selection R × 1k block. Both triodes have a beta value of 100 or more and a small penetration current. Can choose 3DG6 and other types of silicon transistors composed of composite pipe. The multimeter's red and black test leads are connected to the emitter e and collector c of the composite tube, respectively.
- Q: Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
- In the design of high-speed digital circuits, the parasitic inductance of the vias is often more harmful than the parasitic capacitance. Its parasitic series inductance will weaken the contribution of the bypass capacitor, reducing the filtering efficiency of the entire power system. We can use the following formula to simply calculate a parasitic inductance of a vias:
- Q: Why does the circuit current gradually decrease when charging the capacitor?
- The capacitor is a charged container, when the container is full of charge when the internal potential and external potential can reach equilibrium, then the circuit of electrons no longer exercise.
- Q: Capacitance for AC and DC effects?
- In the sine wave AC circuit, the current size of the current flowing through the capacitor can be quantitatively calculated. Specifically, the voltage U is in volts (V), the current I is in the unit (A), the capacitance C is expressed by the law (F) (Ω), the frequency of the AC power supply is expressed in Hertz (Hz) units, and the frequency of the AC power supply is expressed in Hits (Hz)
- Q: What is the difference between polyester film capacitors and ceramic capacitors?
- Good stability. From the chemical performance, acid, alkali, salt and water corrosion of ceramic materials is very small, from the heat resistance, the ceramic material in the high temperature of up to 500 ~ 600 ℃, long-term work without aging
- Q: What is the capacitor, what is the use, where is there?
- Capacitors are important devices in the power system to improve the power factor; in the electronic circuit is to obtain oscillation, filtering, phase shift, bypass, coupling and other major components of the role. Because the load used in the industry is mainly the motor inductive load, so the capacitor and the capacitive load to balance the power grid.
