Shielding Hall Of Hv Pd Test - China

Shielding hall of HV PD test

Application:

HV test shielding room (faraday cage) are Widely used in power cable, transformer, transformer switch, transformer substation and other High voltage levels of partial discharge test or impulse test.

For HV testing shielding room, as a HV test place, it should has good electromagnetic

shielding condition.

And its electromagnetic compatibility always is of great importance.

Firstly, it should restrict electromagnetic wave into inside shielding room caused by

discharge when making HV test to weakening interfere to outside, especially on

electronic and communication system.

Secondly, it should prevent outer

electromagnetic wave intruding into shielding room to cause measurement error of

partial discharge and wireless.

Thirdly, it should reduces open circuit voltage and

closed current to restrain common-mode interference so that to avoid equipment

damage and to improve accuracy of impulse measurement.

For GIS HV test shielding room, design area is 500 m2(Length 25m, Width 20m).

From provided information, we find that steel structure have been completed

already with one set of 20T crane indoor, crane supporting corbel also completed, the

height is 17.9m from ground to upper part of corbel.

Main door height 13m, width 10m, locates at downward of the west side, the door open direction towards to north .

According to ILJIN drawing, three side of structure column has already, but western

structure column still missing yet.

however, as the main door will be located in this side, the western side also should have steel structure, and this structure position still should

be unified considered with main door installation.

We will be able to submit suggested

design diagram with position & size of this structure column for reference.

in order to

save construction cost, the construction engineering will be carried out by ILJIN

team.
