Assembly HV shunt capacitor
1. Introduction
Assembly HV shuntcapacitor is mainly used in 6kv, 10kv, 35kv-class 50%-60Hz power system toimprove power factor.
2. Structure
Capacitor consistsof body, enclosure and tank cover with the characteristics of compact structure, simple installation,small footprint and easy installation and maintenance, etc.
The body is fixedon the shape steel bracket by full sealed capacitor units. The case cover isequipped with pressure release valve and expander (or conservator), inside is filledwith transformer oil.
Capacitor can besingle or three phase. Capacity can be fixed or tap regulating capacitance or Manual(or electric) transfer switch regulating capacitance, the regulatingcapacitance levels are 1/2, 2/2, or 1/3, 2/3, 3/3.
3. Technical feature
Capacitor continuous operation voltage is not greater than 1.05Un, not running out 8hoursper hours in 1.1.
The capacitor is able to operate continuously underthe stable over-current of root mean square value1.3ln caused by over-current and high harmonics.
The capacitancetolerance of Capacitor is 0 ~ +5% of rated value, the ratio of maximum andminimum values of capacitance between any two line terminals in three-phasecapacitor is not more than 1.02.
When the capacitoris under the power frequency rated voltage and 20℃,the loss tangent is not more than 0.0005.
Capacitor can beused for outdoor or indoor. A variety of products shape, size, quality and quantity can be customized according to user needs for humid tropics, plateau area and contamination area and other special circumstances.
- Q: What are the differences between capacitors and capacitors?
- Capacitance, resistance, inductance is physical quantity. Capacitors, resistors, inductors are components that have a specific physical quantity (capacitance, resistance, inductance).
- Q: Use capacitance to do transformer how to calculate
- The principle of capacitor buck is not complicated. His working principle is to use the capacitor at a certain AC signal frequency to produce capacitive reactance to limit the maximum operating current. For example, in the 50Hz frequency conditions, a 1uF capacitance generated by the capacitive reactance of about 3180 ohms. When 220V AC voltage is applied to both ends of the capacitor, the maximum current flowing through the capacitor is about 70mA.
- Q: Cd capacitance to express what
- Mainly speaking, the winding process of the capacitor is a non-inductive winding structure (relative, there is a sense of winding structure), in fact, no sense of capacitance is not no inductance, but the inductance is very small, for high-frequency operation of the capacitor, We emphasize no sense. In fact, the inductance is small. From this point of view, almost all of the metal film capacitors are no sense
- Q: Capacitance can pass high frequency resistance low frequency principle
- The capacitor has a charge and discharge time problem. When the positive half of the AC, to the capacitor charging moment, the circuit is a current flow, the equivalent of the channel, once the capacitor is charged, the circuit will not flow through, the equivalent of open circuit.
- Q: What is the difference between the reactor and the capacitor?
- Reactor is the inductance ah, usually magnetic components plus winding wound, storage of magnetic field energy, the capacitor is stored in the electric field energy.
- Q: How to judge the capacitor is good or bad?
- Due to the amplification of the composite transistor, the measured capacitance of the charge and discharge process to be amplified, so that the multimeter pointer increase the amplitude, so easy to observe. It should be noted that: in the test operation, especially in the measurement of small capacity capacitance, it is necessary to repeatedly change the measured capacitance of the pin contact A, B two points, in order to clearly see the multimeter pointer swing.
- 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: 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: 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 is the difference between polyester film capacitors and ceramic capacitors?
- Ceramic dielectric (type CC) ceramic material dielectric constant ε is very large, so the capacitor volume can be made very small.
