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
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:What is the difference between the power capacitor and the complement?
Input compensation: three-phase co-fill capacitor input, the three groups of capacitors at the same time. The sub-capacitor can be put into operation separately.
Q:How does the capacitor work? What does it do?
The other is the signal filter, that is, the case of alternating current, but also in the AC electrode polarity changes in the process of continuous charge and discharge, in order to AC, if not the capacitance of the two sheds with the amount of change, no matter how the AC can not pass.
Q:What kind of capacitance can be divided into?
Aluminum electrolytic capacitor It is made of aluminum cylinder negative, which is equipped with liquid electrolyte, insert a curved aluminum belt made of positive electrode. Also need to go through the DC voltage treatment, so that the formation of an oxide film on the positive film to do the media. It is characterized by large capacity, but large leakage, large error, poor stability, often used for AC bypass and filter, when the request is not high when used for signal coupling. Electrolytic capacitors are positive and negative points, the use can not be reversed. There are positive and negative polarity, the use of time, positive and negative do not reverse.
Q:Capacitance for AC and DC effects?
Potential has a concept of space, referring to the electric field to a Coulomb charge from A to B work 1 joules, A on the B potential is 1 volt. The concept of potential for the circuit, specify a point of the circuit for the 0 potential, the other points are based on the point of the voltage is the potential of the other points. Electromotive force used in batteries, generators, is the power to generate voltage.
Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
In the design of high-speed digital circuits, the parasitic inductance of the vias is often more harmful than the parasitic capacitance. Its parasitic series inductance will weaken the contribution of the bypass capacitor, reducing the filtering efficiency of the entire power system. We can use the following formula to simply calculate a parasitic inductance of a vias:
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: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: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:Is the capacitor attached to the carbon foil positive?
The above-mentioned positive and negative electrodes are wound around their central axis, and the core of the aluminum electrolytic capacitor is formed. Then, the core is placed in an aluminum shell and the aluminum electrolytic capacitor is formed.
