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: Typically equipped with overload and overvoltage protection, and incorporates built-in mechanical explosion-proof devices, temperature sensors, and other safety protection measures to prevent accidents from escalating.

Small size and light weight: Significantly reduced in size and weight compared to older capacitors.

Long service life: Due to its self-healing function and low loss characteristics, it has a long service life.

Installation and Operation Requirements

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

Ambient Temperature: Pay attention to the impact of ambient temperature on the capacitor's lifespan; avoid prolonged operation at excessively high temperatures.

Installation Space: It should be installed in a well-ventilated location with convenient heat dissipation.

Grounding: Grounding should be performed during installation.

Frequently Asked Questions
Q What is the primary function of a power capacitor?
The primary function is to improve the power factor by compensating for reactive power in the electrical system, which reduces the phase difference between current and voltage and improves overall grid quality.
Q What is the self-healing function in metallized film capacitors?
When a localized dielectric breakdown occurs, the heat generated causes the metallized electrode around the fault point to evaporate and clear, effectively isolating the damaged area. This allows the capacitor to continue operating normally without complete failure.
Q How does improving power factor help reduce electricity costs?
By reducing reactive current flow in transmission lines, capacitors lower line losses and improve power supply efficiency. This means businesses consume less apparent power for the same amount of useful work, directly reducing electricity bills.
Q What safety features are built into these capacitors?
These capacitors are typically equipped with overload and overvoltage protection, built-in mechanical explosion-proof devices, and temperature sensors. These measures work together to detect abnormal conditions early and prevent minor faults from escalating into serious accidents.
Q What should be considered when selecting the rated voltage?
The rated voltage of the capacitor must not be lower than the highest operating voltage of the power grid it will be connected to. An appropriate safety margin should also be factored in to account for voltage fluctuations.
Q What are the key installation requirements for power capacitors?
Capacitors should be installed in a well-ventilated location to ensure adequate heat dissipation. Proper grounding must be carried out during installation, and ambient temperature should be monitored to ensure long-term reliability.
