Custom BSMJ Low-voltage self-healing parallel capacitor Factories, Companies

Low-voltage self-healing parallel capacitors are power electronic components primarily used to improve the power factor of AC power systems. They achieve self-healing after dielectric breakdown through a metallized polypropylene film, thereby improving grid quality, reducing reactive power losses, and extending equipment life. Their main characteristics include small size, light weight, low loss, long lifespan, high safety, and strong withstand voltage and overload capacity.

Product Description

Main Functions and Applications

Improving Power Factor This is the primary function of capacitors. By compensating for reactive power in the system, they reduce the phase difference between current and voltage.

Improving Power Grid Quality Improving the power factor stabilizes grid voltage and reduces voltage fluctuations.

Reducing Losses Reducing the flow of reactive current in transmission lines lowers line losses and improves power supply efficiency.

Saving Costs Improving energy utilization and efficiency helps reduce electricity costs for businesses.

Technical Features

Self-healing function Utilizing a metallized thin-film dielectric, when localized breakdown occurs, the metallized electrode evaporates, isolating the breakdown area and allowing the capacitor to continue operating.

Low loss Employing dry-type technology, it has a low loss tangent (tan delta) and minimal temperature rise during normal operation.

Safe and reliable Equipped with overload and overvoltage protection, including built-in mechanical explosion-proof devices and temperature sensors.

Compact Design Small size and light weight, significantly reduced compared to older capacitor models.

Long service life Due to its self-healing function and low loss characteristics, it ensures long-term operational durability.

Installation and Operation Requirements

Rated Voltage The rated voltage should not be lower than the highest operating voltage of the power grid, with an appropriate safety margin.

Ambient Temperature Pay attention to temperature impacts; avoid prolonged operation at excessively high temperatures to preserve lifespan.

Installation Space Must be installed in a well-ventilated location to ensure convenient heat dissipation.

Grounding Proper grounding must be strictly performed during the installation process for safety.

Are these capacitors safe for industrial environments?

Yes, they are designed with built-in safety measures, including overload protection, overvoltage protection, and mechanical explosion-proof devices.

How does dry-type technology affect performance?

Dry-type technology ensures low loss (low tan delta) and minimal temperature rise, contributing to higher efficiency and a longer service life.

What should be considered during installation?

It is crucial to ensure the rated voltage matches the grid, provide adequate ventilation for heat dissipation, and ensure proper grounding.

Do these capacitors help in reducing electricity bills?

Yes, by improving energy utilization and reducing line losses, they help businesses significantly lower their operational electricity costs.
