Is this matter in the charge of Huaxian Electric Power Bureau?

Generally, only the protection device can automatically stop the operation of the transformer, but it seems that there is no planned power outage, which should be caused by other reasons. If you can't find an electrician, you'd better go directly to the business hall of the electric power bureau, where the service is OK, because everyone is talking about service now. If it really doesn't work, call their service hotline 95598, which is free and convenient.
