High Voltage Reactive Power Compensation Complete Set

YDKTBBZ
Applicable to 6~35kV systems, it provides solutions for power factor correction, improving voltage quality and reducing line losses. The power factor correction device is composed of shunt capacitors, series reactors, zinc oxide lightning arresters, discharge coils, vacuum contactors, disconnectors, fuses, power factor controllers, main circuits and control circuits.
This specification is applicable to shunt capacitors for AC power systems with a frequency of 50Hz or 60Hz and a rated voltage of more than 1kV. The capacitor mainly provides reactive power for industrial frequency AC power systems to improve the power factor of the power grid, reduce losses, improve voltage quality, and give full play to the efficiency of power generation and power supply equipment.
Zhejiang Yide Technology Co., Ltd.'s high-voltage shunt capacitors have excellent performance and reliable quality. The development, design, manufacturing and testing of capacitors strictly follow the requirements of the International Electrotechnical Commission standard IEC60871-1, the national standard GB/T 11024.1~4 and the power industry standard DL/T840, and the key parameters are higher than the standard requirements.
Main structure
1. Main components of capacitors
1.1 The capacitor is mainly composed of a box shell and a body. The body is composed of a core and an outer insulating package. The box shell is filled with a liquid medium as an impregnant. The core is composed of a number of components and insulating parts. The components are made of two aluminum foils and several layers of polypropylene film placed in between, which are rolled and flattened. The components in the core are connected in a certain series-parallel manner to meet the requirements of different voltages and capacitances. In order to improve the partial discharge performance of the product and reduce losses, aluminum foil folding and protrusion welding technology is used.
Each component inside the capacitor with an internal fuse is connected in series with a fuse. When the component breaks down, the intact component connected in parallel with it will discharge it, so that the fuse will melt within milliseconds, ensuring that the faulty component that breaks down is quickly removed. If the capacitance change is within 5%, the capacitor can continue to operate.
1.2 The box shell is welded with thin steel plates or stainless steel plates. The box shell compensates for the change in the volume of the liquid medium inside with temperature by deformation. There is a lead-out bushing on the box cover, and hanging hooks for transportation and installation are welded on both sides of the box wall. A grounding bolt is installed on one side of the hanging hook, with the symbol (some are also equipped with ground feet on both sides of the bottom for installation).
The 2.6kV and 10kV three-phase capacitors are star-connected or led out with independent terminals, and each phase has a discharge resistor.
The technical parameters and performance of capacitors shall be subject to the ordering agreement, and the main parameters are given on the product nameplate. The following are general technical performance.
Capacitors are generally used in places where the ambient air temperature is -40℃~+45℃ (i.e. -40/B), and the installation area is not more than 1000m above sea level. Products with a suffix "G" in the model can be used at an altitude of more than 1000m. When ordering with special requirements, special instructions should be given.
The capacitance deviation of the capacitor shall not exceed -3%~+5% of the rated value. The ratio of the maximum to minimum capacitance measured between any two line terminals in the three-phase capacitor: 200kvar and below is not greater than 1.05, and 200kvar and above is not greater than 1.02.
The loss tangent of the capacitor at a temperature of 20℃, measured at rated frequency and rated voltage, shall comply with the following provisions: The impregnated full-film dielectric capacitor with discharge resistance and internal fuse shall not be greater than 0.0003, without discharge resistance and internal fuse shall not be greater than 0.0002.
Dielectric strength:
The dielectric between the capacitor terminals should be able to withstand one of the following two test voltages for 10 s.
A. Power frequency AC voltage: 2.15Un (Un is the rated voltage)
B. DC voltage: 4.3Un
The test voltage of three-phase capacitors should be adjusted appropriately to ensure that each phase withstands the above withstand voltage value.
The insulation level between the capacitor terminals and the casing should be able to withstand the test voltage listed in Table 1:

The capacitor is allowed to operate for 8 hours in every 24 hours at a voltage not exceeding 1.1 times the rated voltage, and can operate for no more than 30 minutes per day and night at a voltage of 1.15 times the rated voltage (except for transient overvoltage). In order to extend the service life of the capacitor, the capacitor should always be kept operating at a voltage not exceeding the rated voltage. (See Table 2 for details)

*Note: The overvoltage higher than 1.15Un in the table should occur no more than 200 times during the life of the capacitor. The capacitor is allowed to operate for a long time at a current not exceeding 1.3 times the rated current due to voltage rise and high-order harmonics. For capacitors with the maximum positive deviation of capacitance, this overcurrent is allowed to reach 1.37 times the rated current. If the capacitor operates for a long time at a voltage not exceeding 1.10Un, the voltage value including all harmonic components should not exceed 1.2√2un.
Note: The rated current of the capacitor refers to the current passed by the capacitor of rated capacity under sine wave, rated frequency and rated voltage.
Mechanical strength of capacitor bushing and conductive rod
Solder bushing
A. Capacitor bushings below 200kvar should be able to withstand 400N horizontal tension.
B. Capacitor bushings between 200kvar and 1000kvar should be able to withstand 500N horizontal tension.
C. Capacitor bushings above 1000kvar should be able to withstand 900N horizontal tension.
D. The torque that the capacitor conductive rod can withstand should meet the requirements of Table 3

Crimp bushing
A. Static tension parallel to the center line of the bushing is 1500N.
B. Static tension perpendicular to the center line of the bushing is 1000N.
C. The maximum torque of the nut wrench is 40N-m.
After the capacitor with internal discharge resistor is disconnected from the power supply, it can drop from the peak value of the rated voltage to below 75V within 10min. if it is to drop from the peak value of the rated voltage to below 50V within 5min or other technical requirements, it should be specified when ordering.
