2.1 Purpose of the device

The TZY-YZG overvoltage suppression cabinet is suitable for medium voltage power systems ranging from 3 to 35 kV. This product is widely used in power systems with neutral points not grounded, neutral points grounded through arc suppression coils, or neutral points grounded through high resistance. It can limit various types of overvoltage in the above systems and effectively improve the operation and power supply reliability of the above systems.

2.2 Characteristics of the device

It can limit various types of overvoltage to a lower level, greatly reducing insulation accidents caused by overvoltage.

The probability of metal oxide zinc arrester (MOA) explosion in such power grids is greatly reduced.

The system does not require any additional harmonic elimination devices, and its effectiveness is better.

The entire device and PT form a high-voltage switchgear, with a simple structure, small size, easy installation and debugging, and a wide range of applications.
