Herong High Voltage Capacitor Bank Hight Voltage Shunt Power Capacitor

Hight Voltage Shunt Capacitor/High Voltage Capacitor Bank

1. Overview of High Voltage Shunt Capacitor

      The shunt capacitor is composed of several parts, such as the core, the shell, and the outgoing porcelain sleeve. The two sides of the box wall are welded with hangers for installation, and one side of the hangers is equipped with grounding bolts. The core of the capacitor is composed of several components and insulating parts. In order to adapt to various voltages, the core is composed of several small components connected in parallel and connected in series. The capacitor is equipped with a discharge resistor inside, and the outer shell is formed and welded by stainless steel plate.

2. Function

       High-voltage shunt capacitors are suitable for 50Hz or 60Hz AC power systems to improve the power factor of power frequency power systems, reduce line losses, improve the quality of supply voltage, and increase the active output of transformers.

3. Main features

• 3.1 Casing: Cold-pressed, anti-fouling type casing is adopted, and the creepage distance is not less than 31mm/kV.
• 3.2 Mature internal fuse technology.
• 3.2.1 After testing, the internal fuse can isolate the faulty component within 0.2ms, the release energy of the fault point is not more than 0.3kJ, and the remaining intact components are not affected.
• 3.2.2 Advanced concealed internal fuse structure, using oil gap arc extinguishing, reducing the possibility of blasting the capacitor case.
• 3.2.3 The internal fuse protection and relay protection have perfect coordination standards to ensure the safe and reliable operation of the entire device.
• 3.3 Liquid medium: 100% insulation oil (NO PCB) is used. This liquid has excellent low temperature performance and partial discharge performance.
• 3.4 The main insulation adopts a composite insulation structure, which not only guarantees excellent electrical performance, but also has a certain degree of mechanical strength, which ensures that the insulation of the capacitor complete set of devices is 100% reliable without protection.
• 3.5 Good sealing performance: The annual leakage rate is less than 0.1%, and the sealing performance of the capacitor is guaranteed through measures such as automatic argon arc welding, vacuum leak testing, and thermal aging.
• 3.6 Partial discharge level: the extinguishing voltage is not less than 1.5Un, and each capacitor is tested for partial discharge during production.
