Highest temperature: -40℃~+40℃
Installation andoperation site shall be no conductivity and no explosiveness dust, no harmfulgases and steam, no ferocity mechanical shock.
Installation site:Indoor or outdoor
3. Structure
Complete set of shuntcapacitor consists of shunt capacitor, series reactor, discharge coil, oxidearrester, disconnecting earth switch. Shunt capacitor, lying down or standingon steel frame, is connected according to certain electrical requirement, the devicecan be transported as a whole or parts, easy to installation, and can be equippedwith security net as well as designed and produced in various combination ways uponcustomer’s request, dry type core series reactor is suitable for indoor.
4. Main technological performance
Capacitance deviation:the ratio between measured capacitance and rated capacitance per phase is notmore than 0~+0.5%, the ratio between max. capacitance and min. capacitance amongthree phase is not more than 1.02.
The device is ableto operate under 1.05 times rated voltage for a long time.
The device is ableto operate continuously when the root mean square value is not more than 1.3times rated current. The over current is caused by harmonics and over-voltage.

8.1 Technical parameter for cabinet type shunt capacitor compensation device
8.2 Thechinal parameters for frame type shunt capacitor compensation device
- 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:What is the electrolytic capacitor inside?
- Electrolytic capacitor features three: the price than other types have overwhelming advantages, because the composition of electrolytic capacitors are common industrial materials, such as aluminum and so on.
- Q:How does the capacitor work? What does it do?
- Capacitance works: the principle of charge and discharge simply put the capacitor is the two poles charged or discharge, that is, charge diffusion. Charge and discharge capacitors should be connected in series, can be connected in parallel; it is the basis of other properties of capacitance. The phenomenon of intermittent communication is the embodiment of charge and discharge, if it is DC, charged to stop, the capacitor charged; if it is alternating current, is constantly charging discharge. Complete the transmission of AC.
- Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
- With the increase in stray inductance, IGBT turn-on loss will be reduced, the diode loss will increase. Stray inductance may also cause oscillations, such as oscillations caused by current mutations, which may result in limited device use due to EMI or overvoltage limits.
- Q:What are the differences between capacitors and capacitors?
- Capacitance is a large category, and capacitors are subclasses of capacitors. Capacitors can be divided into cbb capacitors, aluminum electrolytic capacitors, safety capacitors and so on. Different categories, the difference is still relatively large
- 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 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 principle of capacitance isolation?
- When the supply voltage rises in the reverse direction, the capacitor is charged in the reverse direction, and then the discharge is reversed. So the charge and discharge and the AC current is really the same, so the capacitor can pass the AC current.
- Q:How to use the capacitor
- Solid-state aluminum capacitors have positive and negative points, do not reverse the solid-state aluminum capacitors, reverse solid capacitors can lead to a sharp increase in leakage current or reduced service life.
- 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;
