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:How does the capacitor work? What does it do?
- The bypass capacitor is an energy storage device that provides energy to the local device, which can equalize the output of the regulator and reduce the load demand. Like a small rechargeable battery, the bypass capacitor can be charged and discharged to the device. To minimize the impedance, the bypass capacitor should be as close as possible to the load device's power supply pin and ground pin.
- 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 relationship between capacitance and voltage?
- In your case, you can think of two capacitors as two containers, 5v capacity than 10v half (because they are 0.01uF),
- 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:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
- This impedance can not be ignored in the presence of high frequency current, with particular note that the bypass capacitor needs to pass through the two vias when connecting the power plane and the formation so that the parasitic inductance of the vias is multiplied.
- Q:Low voltage capacitor voltage 0.45 and 0.4 What is the difference between usage
- Can be used in the low-voltage three-phase power lines on the line, but the level of different pressure, connected to the 400V line, 450V capacitor capacity is 79% of rated capacity, 400V capacitor capacity is rated capacity. In the use of life on the 450V longer than 400V
- 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:Why does the circuit current gradually decrease when charging the capacitor?
- The capacitor is a charged container, when the container is full of charge when the internal potential and external potential can reach equilibrium, then the circuit of electrons no longer exercise.
- Q:What is the capacitor, what is the use, where is there?
- Capacitor is the storage of the charge of the container, usually by two pieces of metal foil (or metal film) in the interval between the air, paper, mica, plastic film and other insulating materials. Commonly used to improve the power factor, start single-phase asynchronous motor,
- Q:How to judge the capacitor is good or bad?
- 10pF below the fixed capacitor capacity is too small, with a multimeter to measure, only qualitative check whether there is leakage, internal short circuit or breakdown phenomenon.
