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: 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: Use capacitance to do transformer how to calculate
- According to this feature, if we connect a resistive element in series with a 1uF capacitor, the voltage obtained at both ends of the resistive element and the power dissipation it generates depends entirely on the characteristics of the resistive element.
- Q: What is the relationship between capacitance and voltage?
- when you charge 5v, want to be in the first The capacitor is full, the second capacitor half; if you charge a higher voltage 6v, then the first capacitor to diffuse out, the actual performance of the capacitor was breakdown!
- Q: Capacitance can pass high frequency resistance low frequency principle
- When the negative half of the alternating current arrives, it will generate the current, first offset the original charge on the capacitor that the opposite charge, continue to charge to full.
- 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?
- 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: On the ground resistance, what role the capacitor
- Filter: The capacitor used in the filter circuit is called the filter capacitor, in the power supply filter and a variety of filter circuit using this capacitor circuit, filter capacitor will be a certain band of the signal from the total signal removed.
- Q: How to identify high voltage capacitors is good or bad
- This is a special place for high voltage capacitors in microwave ovens. Because in this capacitor in parallel with a 10M capacitor. So the capacitor does not leak when the final resistance is 10M. Not infinity
- Q: How does the capacitor work? What does it do?
- Straight to pass on the circuit need to pass the AC signal, power supply filter, cut off DC and other places to use. Capacitor charge and discharge is the basis of other properties. There are two kinds of filtering, one is the power filter, which is more obvious charge and discharge, can be seen as a container.
- Q: What is the difference between polyester film capacitors and ceramic capacitors?
- Polyester capacitor medium for the polyester film, its capacity and pressure range, small size, large capacity, high temperature, low cost. But tgδ with the frequency changes, it is used for tgδ, stability and loss requirements are not high occasions, such as DC and pulsating circuit.
