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.

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:What is the use of capacitors?
- As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:
- Q:What kind of capacitance can be divided into?
- Capacitors are often called capacitors. According to its structure can be divided into fixed capacitors, semi-variable capacitors, variable capacitors three.
- Q:What is the electrolytic capacitor inside?
- Electrolytic capacitor inside the composition of the structure: two close to each other with a coating with polarity, positive and negative metal electrode plate, the middle folder with insulating material (medium for the electrolyte,) constitute
- Q:What is the phase-shifting capacitor, what is the difference between it and the general capacitor
- And the phase-shifting capacitor has the function of changing the phase of the alternating current signal in addition to the characteristics of the general capacitor. The answer can be compensated by the power factor compensation in parallel with the phase-shifting capacitor, and the phase-shifting capacitor can be used to produce the phase-shifting capacitor fault diagnosis device.
- Q:How to use the capacitor
- The sum of the DC voltage and the ripple peak voltage shall not exceed the rated operating voltage;
- Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
- This impedance can not be ignored in the presence of high frequency current, with particular note that the bypass capacitor needs to pass through the two vias when connecting the power plane and the formation so that the parasitic inductance of the vias is multiplied.
- 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 is the difference between polyester film capacitors and ceramic capacitors?
- The frequency characteristics of the capacitor is better than the polyester, the capacitance and tgδ with the frequency of small changes can be used in low-voltage AC-DC circuit.
- Q:Why some Y capacitor is very small, and some Y capacitor is very large?
- At the AC power input, it is generally necessary to add three safety capacitors to suppress EMI conduction interference. AC power input is divided into three terminals: FireWire (L) / Neutral (N) / Ground (G). Between the line of fire and the ground and between the zero line and ground in parallel with the capacitor, generally referred to as Y capacitor. The two Y-capacitor connection position is more critical, must meet the relevant safety standards, to prevent electronic equipment leakage or chassis charged, easy to endanger personal safety and life.
- 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.
