Transformer gas relay

Abstract

The invention relates to a transformer gas relay characterized in that a vent valve on the top of the transformer gas relay is connected with an exhaust pipe and the exhaust pipe passes through the housing of the transformer gas relay to extend out of the housing. The transformer gas relay may effectively guarantee the safe and stable operation of power grid equipment, improves the reliability of power supply, shortens the stop time of equipment overhaul, reduces the labor intensity of overhaul workers and maintenance cost, guarantees the personal safety of operation and maintenance workers, saves manpower, and increases work efficiency.

Description

technical field [0001] The invention relates to a transformer protection device, in particular to a transformer gas relay. Background technique [0002] During the operation of the main transformer in the power system, due to the frequent actions of the on-load tap changer, the arc generated during the action will vaporize the transformer oil, causing gas to be generated inside the mechanism, resulting in gas accumulation at the upper end of the on-load gas relay of the main transformer. Therefore, maintenance is required Personnel carry out exhaust work. There are two ways for maintenance personnel to perform exhaust operations, one is to deal with power outages, and the other is to deal with electrification. If you choose power-off treatment, the transformer under load needs to be out of operation, which reduces the reliability of the power system power supply during the operation; , it is easy to cause electric shock accidents; second, the maintenance personnel need to ...

AI Technical Summary

Problems solved by technology

If you choose power-off treatment, the transformer under load needs to be out of operation, which reduces the reliability of the power system power supply during the operation; , it is easy to cause electric shock accidents; second, the maintenance personnel need to climb up to work; third, the oil leaking from the exhaust gas is not cleaned thoroughly, which will cause the illusion of oil leakage from the gas relay; fourth, frequent air release is easy to cause The components of the sealing device are loose and oil leaks, which in turn causes the gas relay to malfunction

Furthermore, such faults need to be reported first, and the defect handling procedure can be followed before the deflation process can be performed. In this way, the defect cannot be solved in the first time, and the hidden danger of accidents will be increased.

In addition, it will also involve the loss of manpower, vehicles and materials
