Abstract

The invention relates to a transformer power-on self-locking alarm protective safety case, including a case body and a door arranged on the case body, and an electromagnetic lock arranged on the door,and an alarm apparatus and a controller arranged on the case body. The electromagnetic lock comprises a bolt, a coil coiled on the bolt, and a housing covered on the bolt. The coil is in the housing,and the coil is connected with a low-voltage side of a transformer. The part of the bolt, extending out of the housing, is cooperated with a lock groove on a case body door frame. The front end closeto the bolt is provided with a fixing plate. A pot head is provided with a spring. One end of the spring is fixedly connected with the fixing plate, and the other end is connected with a tension sensor which is arranged on the case body. The external diameter of the fixing plate is smaller than internal diameter of the lock groove. The tension sensor is connected with the controller. The controller is connected with the alarm apparatus. Using the transformer power-on self-locking alarm protective safety case in the technical scheme, the door is locked after the transformer is powered on, to prevent occurrence of electric shock accidents. Under the condition of forcing to open the case body door, the case has warning effect.
