Wetown series capacitors are specially used for low-voltage tuning filter systems and low-voltage detuning filter systems. At present, the market to solve the harmonic problem mainly includes low-voltage tuning filter system and low-voltage detuning filter system. Because harmonics will accelerate the aging effect on the insulation of power equipment, the voltage peak after harmonic superposition has a great effect on the aging of metallized film capacitors. Impact. Wetown capacitors are specially improved from the aspects of material ion, technology and test methods, and produced capacitors specially used for low-voltage tuning filter systems and low-voltage detuning filter systems.

The capacitor’s built-in secondary linkage protection device can be used in series with the

contactor or the control end of the switching device. When the passive filter series reactor is used

in parallel with multiple capacitors, it can protect the low-voltage passive filter and prevent the

electric The change in capacity caused the failure to expand further.

Each capacitor has a built-in over-pressure protection device and discharge resistor to ensure that

the capacitor will not burn or burst at the end of its life, and ensure the safety of electricity.

The metallized film electrode adopts zinc-aluminum composite technology. The thickness of the

electrode is very thin. When the inside of the container is electrically overloaded or the

temperature is too high, electrical breakdown occurs, and the electrode around the breakdown

point is ionized, and the breakdown point makes the electrode dielectric layer The gasification is

separated to produce an insulating zone, and the capacitor restores its normal working ability.

The capacitor adopts an aluminum shell with a dry structure inside and does not contain any oil.

After injecting special gas into the capacitor, it is filled with dry resin to ensure that the product will

not explode, burn, or leak oil.

Each  capacitor has a discharge resistor installed. Three minutes after the capacitor is

disconnected from the power supply, the voltage on the terminal is discharged through the

internal discharge resistor, and the voltage drops below 50V to protect the safety of the operator.
