The specialised technicians of demiks, a manufacturer of substation equipment, point out that the,The partial discharge shielding room is a special laboratory or closed space, which is mainly used for partial discharge testing of high voltage equipment. Partial discharge is a small-scale corona discharge phenomenon that occurs in the electrical insulation system, which may cause damage to the insulation system and eventually lead to equipment failure. The main function of the partial discharge shielding room is to reduce electromagnetic radiation and electric field interference through its special metal shielding structure and insulating materials. So how does the partial discharge test shielding room ensure a closed environment for high voltage partial discharge testing?

The following are the general working environment requirements of the partial discharge test shielding room of Shanghai Demix Electric Power Technology Co., Ltd.:

1. Metal shielding: The partial discharge test shielding room should be made of metal materials such as copper or aluminum, and must have good shielding capabilities to reduce the impact of electromagnetic interference on the outside world.

2. Grounding system: It is very important to establish a good grounding system to ensure that the current can effectively flow back to the site through the ground, prevent accidental electric shock and maintain the stability of the test environment.

3. Shielding sealing: The doors and other openings of the shielding room built by Demix have good sealing performance to prevent electromagnetic fields from leaking into the external environment while maintaining the stability of the test environment.

4. Safety equipment: Appropriate safety equipment should be equipped in the shielding room, such as emergency stop button, leakage protection device, etc., to ensure the safety of operators.

5. Temperature control: In order to maintain the stability of the test environment, the Demix partial discharge test shielding room usually needs to be installed with a temperature control system, which can cool or heat the test room as needed.

Common partial discharge shielding test rooms are of two types: assembled and welded. The assembled type is assembled by screws using steel plate modules, while the welded type is welded by welding steel plates to keels. When users determine the construction of a partial discharge shielding test room, which form is better? Based on the engineering project experience and experience of Shanghai Demix Power Test Engineers over the years, Demix Power Test Engineers made a brief comparison of plate, module manufacturing, production process, construction cycle, manufacturing cost and test room size, hoping to provide some reference for everyone.
