Product Description:

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:On the ground resistance, what role the capacitor
Decoupling: The capacitor used in the decoupling circuit is called the decoupling capacitor. This capacitor circuit is used in the DC voltage supply circuit of the multi-stage amplifier. The decoupling capacitor eliminates the harmful low frequency cross-connection between the amplifiers.
Q:Capacitance for AC and DC effects?
Current waveform ahead of the voltage 90 degrees, in a sine wave cycle, half of the time ( Voltage waveform 0-90 degrees and 180-270 degrees) power to charge the capacitor, while the other half of the time (voltage waveform 90-180 degrees and 270-0 degrees) capacitance of the power discharge, the power and intact return power The
Q:How to judge the capacitor is good or bad?
Multimeter selection R × 1k block. Both triodes have a beta value of 100 or more and a small penetration current. Can choose 3DG6 and other types of silicon transistors composed of composite pipe. The multimeter's red and black test leads are connected to the emitter e and collector c of the composite tube, respectively.
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:How to use the capacitor
High temperature no load test test, high temperature and high humidity load test, temperature jerk test and so may lead to increased leakage current. Therefore, do not apply solid-state aluminum capacitors to leak-current-sensitive circuits
Q:What is the principle of capacitance isolation?
When the capacitor is connected to the AC circuit, there is also a charging process in which the charge is stopped when the capacitor voltage is equal to the supply voltage, and then the power supply voltage drops and the capacitor begins to discharge.
Q:Does the size of the capacitor affect the power consumption?
The capacitance is the physical quantity that characterizes the capacity of the capacitor to charge the charge.We charge the capacitance of the capacitor by increasing the potential difference between the two plates of the capacitor by one volt.
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:Cd capacitance to express what
No capacitance is used in the high-frequency circuit of a capacitor, this capacitor without pins or pins shorter, commonly used in the tuner; generally PF level, the so-called "no sense" is the capacitor work is not produce "inductance" Effect, because C (capacitance) + L (inductance) = R (resistance), (when the match is good), if so, the circuit will not work.
Q:Why does the circuit current gradually decrease when charging the capacitor?
due to the increase in the number of charge, the electrostatic field field strength will gradually increase, increasing the field strength caused by the absorption of electrons to produce exclusion, So that the number of adsorbed charges gradually reduced, the number of charge to reduce the performance of the phenomenon that the charging current is gradually reduced. When the number of charges on the two electrode plates of the capacitor reaches a gradually increasing field strength constraint, the amount of charge is not increased and the equilibrium state is reached, that is, the charge saturation current is zero.
