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: Is the capacitor attached to the carbon foil positive?
- Electrolytic capacitors of the positive plate with aluminum foil, immersed in the electrolyte for anodic oxidation treatment, aluminum foil surface will produce a layer of aluminum oxide film, the thickness is generally 0.02 - 0.03μm. This layer of oxide film is positive and negative insulation between the plates.
- Q: Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
- 0.45 and 0.4 capacitors are capacitors that rated the line voltage of 0.45kV and 0.4kV; they are suitable for 380V voltage systems, the difference lies in their pressure rating;
- Q: How to use the capacitor
- Circuites that are forbidden use: Even if the customer installs a solid-state aluminum capacitor in strict accordance with the welding conditions we have given, the leakage current of the solid-state aluminum capacitor may also increase or even increase significantly.
- Q: What kind of capacitance can be divided into?
- Commonly used capacitor structure and characteristics Commonly used capacitors can be divided into their dielectric materials electrolytic capacitors, mica capacitors, ceramic capacitors, glass glaze capacitors and so on.
- Q: What is the relationship between capacitance and voltage?
- In your case, you can think of two capacitors as two containers, 5v capacity than 10v half (because they are 0.01uF),
- Q: Cd capacitance to express what
- Mainly used in high voltage, high current and high pulse circuit, such as buffer, energy converter, switching power supply, inverter and inverter protection circuit, especially for IGBT, SCR, Darlington line For absorption capacitors.
- Q: What is the difference between the reactor and the capacitor?
- Capacitors in order to boost, so that the voltage ahead; reactor in order to buck, so that the voltage lag; they are in the system are reactive power, improve power quality
- Q: How to judge the capacitor is good or bad?
- Measurement, the choice of multimeter R × 10k block, with two test leads were any then the capacitor of the two pins, the resistance should be infinite. If the measured resistance (pointer to the right swing) is zero, then the capacitor leakage damage or internal breakdown.
- Q: Why some Y capacitor is very small, and some Y capacitor is very large?
- As a capacitor of the Y capacitor, it is required to obtain the certification of the safety inspection mechanism. Y capacitor appearance is mostly orange or blue, are generally marked with safety certification mark (such as UL, CSA and other logo) and pressure AC250V or AC275V words. However, its true DC withstand voltage is above 5000V. It must be emphasized that the Y capacitor can not be used with a nominal capacitor such as the nominal voltage AC250V or DC400V.
- Q: How to identify high voltage capacitors is good or bad
- There is a series in 220v AC power inside, see if the light bulb can be normal light. Determine if the capacitor has capacity. Whether the initial test is normal.
