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: 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.
- 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 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: 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: 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: What is the principle of capacitance isolation?
- When the capacitor is connected to the DC circuit, there will be a brief charging process. When the positive and negative plates are filled with charge (when the voltage across the capacitor is equal to the supply voltage), there is no current and then flow, so the capacitor is isolated DC current
- 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 electrolytic capacitor inside?
- Electrolytic Capacitor Features 1: the capacity of the unit volume is very large, tens of tons to several hundred times larger than other types of capacitors. Electrolytic capacitor features two: rated capacity can be very large, you can easily do tens of thousands of μf or even f (but not with the electric layer capacitance ratio).
- Q: Why does the circuit current gradually decrease when charging the capacitor?
- Why does the circuit current gradually decrease when charging the capacitor? Because the charge began to charge the capacitor, the capacitor two electrode plate charge began to zero, the electrostatic field is zero, the absorption of electrons is not exclusion, the performance of the phenomenon is the beginning of the charge when the circuit current is very large, with the capacitor The charging time increases, there will be more and more charge adsorption on the capacitor two electrode plates,
- Q: Capacitance for AC and DC effects?
- In the sine wave AC circuit, the current size of the current flowing through the capacitor can be quantitatively calculated. Specifically, the voltage U is in volts (V), the current I is in the unit (A), the capacitance C is expressed by the law (F) (Ω), the frequency of the AC power supply is expressed in Hertz (Hz) units, and the frequency of the AC power supply is expressed in Hits (Hz)
