6 FAQs about [Automatic discharge of compensation capacitor]

How a capacitor compensation circuit is controlled?

Through the logic drive circuit, pulse width modulation circuit, zero point detection circuit and power factor detection circuit, the on-off of the self-turning off device in the switch circuit was controlled to control the charging and discharging voltage of the compensation capacitor, and then the capacitor compensation current was controlled.

How long does a capacitor need to be discharged?

As per IEC 60831:2014 capacitors need to be discharged to 75 V within 3 minutes. All capacitors are supplied with a discharge resistor according to the requirements of the standard. Before switching on again, capacitors must be discharged to 10% or less of their nominal voltage. 135,000 hrs. 150,000 hrs. Substantially improved performance (max.

What are the types of compensation capacitors?

Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.

Do capacitors need a discharge resistor?

How to Mount alpican capacitor?

Mounting is done with a stud at the bottom of the capacitor. Alpican is designed and made for long life and low losses during the operation. Thus making it one of the most energy eficient capacitors. Non-PCB semi-dry resin reduces the risks of leaking.

What is a power factor automatic compensation control device?

The power factor automatic compensation control device of the self-turning off device manufactured by this method has the characteristics of simple structure, small volume and high efficiency, and can automatically carry out random power factor compensation for the electric load on site.
