Product Detail

Overview

 The shunt capacitor is composed of a pack, a case, an outlet porcelain busing, etc. The two sides of stainless steel case are welded with hanging brackets for installation, and one hanging bracket is equipped with a grounding bolt. In order to adapt to various voltages, the pack is composed of several small elements connected in parallel and series. The capacitor is equipped with a discharge resistor.

Main features

  • Casing: Cold-pressed, anti-fouling type casing is adopted, and the creepage distance is not less than 31mm/kV.

  • Mature internal fuse technology.

  • 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.

  • Advanced concealed internal fuse structure, using oil gap arc extinguishing, reducing the possibility of blasting the capacitor case.

  • The internal fuse protection and relay protection have perfect coordination standards to ensure the safe and reliable operation of the entire device.

  • Liquid medium: 100% insulation oil (NO PCB) is used. This liquid has excellent low temperature performance and partial discharge performance.

  • 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.

  • 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.

  • Partial discharge level: the extinguishing voltage is not less than 1.5Un, and each capacitor is tested for partial discharge during production.

Parameters

 Medium voltage shunt capacitor/High voltage shunt capacitor are suitable for 50Hz or 60Hz AC power systems to improve the power factor of the power system, reduce line losses, improve the quality of the power supply voltage, and increase the active output of the transformer.

How does a transformer work?
Transformer Operation PrincipleA transformer is an electrical device that operates on the principle of electromagnetic induction to transfer electrical energy from one circuit to another. It enables the adjustment of voltage levels within an alternating current (AC) system, either stepping up (increasing) or stepping down (decreasing) voltage while maintaining the same frequency.Working Principle:Basic ComponentsA transformer consists of two coils, known as windings—the "primary winding" connect

Withstand voltage test of high-voltage cables
Withstand voltage test is an insulation test, but it is a destructive test that can reveal insulation defects difficult to detect in non-destructive testing.The test cycle for high-voltage cables is three years, and it must be conducted after non-destructive tests. In other words, the withstand voltage test is performed only after all non-destructive tests have been passed.Most high-voltage cables used today are cross-linked polyethylene (XLPE) cables, which can have large cross-sections and cov

Analysis of Abnormal Causes of High-Voltage Cable Grounding Circulation and Typical Cases
I. Introduction to Cable Grounding Loop CurrentCables rated 110 kV and above use a single-core structure. The alternating magnetic field generated by the operating current induces a voltage on the metallic sheath. If the sheath forms a closed circuit through the earth, a grounding loop current will flow on the metallic sheath. Excessive grounding loop current (loop current exceeding 50 A, more than 20% of the load current, or a ratio of maximum-to-minimum phase current greater than 3) not only a
