What is the function of the high-voltage parallel capacitor outlet sleeve

In the construction of high-voltage capacitors, outgoing bushings and incoming bushings play an important role. The outgoing bushing serves as a bridge between the internal current of the capacitor and the external circuit. Its design is precise and needs to take into account current capacity, voltage level and insulation performance to ensure stable current extraction in a high-voltage environment.

The outgoing bushing of high-voltage shunt capacitors mainly plays the following roles:

1. Provide electrical connection

The outgoing bushing is the electrical connection between the capacitor and the external power grid, ensuring that the capacitor can be connected to the high-voltage lines of the power grid. Through outgoing bushings, capacitors can transfer compensated reactive power to the grid.

2. Insulation effect

The outgoing bushing of a high-voltage parallel capacitor needs to provide good insulation properties to ensure that the electrical connection part of the capacitor will not short circuit or leak electricity to the ground or other equipment. The insulating material of outgoing bushing usually has high voltage tolerance to prevent high voltage damage to equipment or cause safety hazards.

3. Protective role

The outgoing bushing also plays a certain physical protection role, preventing the capacitor's terminals from being affected by the external environment, such as rain, dust or mechanical damage. At the same time, the bushing can also prevent external objects from contacting the high-voltage terminal, ensuring the safety of operators.

4. Electrical protection

The outgoing bushings of some high-voltage parallel capacitors may also be designed with protective devices, such as fire protection, corrosion resistance and other characteristics, to adapt to different working environments and ensure long-term reliable operation of electrical equipment.

Therefore, outgoing bushing is not only a connecting component, but also an important part to ensure the safe and stable operation of capacitors.
