B, Gas protection: In the event of a fault inside the transformer tank, it is mainly (B) that comes into action.
When a fault occurs inside the transformer tank, it is mainly (B, gas protection) that comes into action.
When a fault occurs inside the transformer tank, it is mainly ( ) that takes action. A. Current quick-break protection B. Gas protection C. Differential protection D. Overcurrent protection If this is a single-choice question, the answer is “B”; if it’s a multiple-choice question, the answers are “B, C”. When a fault occurs inside the oil tank of an oil-immersed transformer, it causes the transformer oil to vaporize. These gases enter the gas relay, triggering the \"light gas\" protection mechanism to issue an alarm. In the case of a severe fault, it also leads to changes in the pressure inside the oil tank; the transformer oil inside flows rapidly toward the oil conservator to relieve pressure, which in turn activates the \"heavy gas\" protection mechanism of the gas relay. An inter-phase short circuit inside the fuel tank can also cause the \"differential\" protection to activate.
