BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the
information provided herein is prior art or relevant to the presently claimed
invention, or that any publication specifically or implicitly referenced is prior art.
[0003] A gas insulated switchgear is a sealed device which has to retain
insulating gas inside the tank for a prescribed time, the switchgear is designed to
carry normal rated current throughout the service life apart from other functions.
For validation of this function, temperature rise test is required to be performed as
per respective standard. Rated current is injected through the power path and
maximum temperature is measured at critical parts in the power path. For
measurement of the temperature rise various arrangements are used, one of the
most popular & proven arrangement is by using thermocouples. Thermocouple
tips are mounted or fixed on the critical parts and the other end of the
thermocouple is connected to the measurement system. Type & length of the
thermocouple is selected depending on the application, temperature range & other
parameters. In gas insulated switchgear all the power parts are housed inside the
sealed chamber hence facilitating thermocouple inside sealed tank of the gas
insulated switchgear is a tough task. Any small cavity, crack or gap may lead to
gas leakage which is not a desirable situation and rework of the joint becomes
necessary to fill the gap. This is a tedious and time taking activity. In few designs
the switchgear may have to be replaced which involves high cost and extra time.
[0004] There is, therefore, a need of an improved arrangement or system
for facilitating temperature sensing devices inside a sealed tank of the gas insulated switchgear without causing any risk of gas leakage from the sealed tank.
