A quick grounding device applied to high and low voltage winding of dry-type transformer

Abstract

The utility model discloses a dry -type transformer high, low voltage side winding quick grounding device, solve traditional manual grounding operation efficiency low, connection is not stable and the problem of potential safety hazard. The device includes the lifting seat of vertical sliding in the top of transformer shell, is equipped with the clamping body of corresponding high, low voltage terminal on it, and the clamping body connects the ground wire and is connected in series AC power supply, circuit breaker etc. There is the motor and screw rod of driving lifting seat in the shell, and the guide column ensures the stable lifting, and the connecting frame makes the clamping body accurate butt joint terminal, and the clamping body arc groove adapts the outside diameter of terminal. Infrared sensor cooperates with reflector, and the clamping body contact position is accurately controlled. The ground wire is connected through the wire wheel and the tensioning structure, and keeps tension through the movable pulley and spring. The device can automatically complete high, low voltage side winding grounding fast, and the operation is convenient, and the connection is reliable, avoids the hidden danger of manual operation, and improves the grounding efficiency and safety.
