Abstract
The invention discloses a secondary loop access device for a transformer substation. A push rod motor is connected with one end, far away from an electric telescopic device, of each telescopic pole, wherein push rods of the push rod motors are fixedly connected with insulating bolts; the push rods of the push rod motors are provided with springs in the circumferential direction; one end of each spring is fixedly connected with the corresponding push rod motor; one end, far away from the corresponding push rod motor, of each spring is fixedly connected to the lower end of the corresponding insulating bolt; and the electric telescopic device and the push rod motors are electrically connected with a controller. By the secondary loop access device for the transformer substation, the lengths of the telescopic poles are adjusted according to the distance between inner loop connecting sheets; two insulating bolts are controlled through a handle and are controlled only by one hand; through the arranged springs, the insertion speed of each insulating bolt is reduced; and insertion is relative accurate. An inner loop is disconnected or connected by the insulating bolts in an inserting or withdrawing manner, so that the target that an outer loop is conveniently connected to and withdrawn from the loop is achieved; and the secondary loop access device is simple in structure and reliable to work.
