2results about How to "Quick ground" patented technology

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.

The utility model provides a discharge circuit and an electronic device, when the electronic device is powered on, a voltage dividing loop divides the voltage of a power supply and then provides a voltage signal to a time delay circuit, so that the time delay circuit is conducted, the discharge loop is turned off, the electronic device is normally powered on and works, and when the electronic device is powered off, the time delay circuit is turned off. And when the voltage signal cannot maintain the conduction of the time delay loop, the time delay loop is switched off, and at the moment, the discharge loop is conducted, so that the power supply is quickly grounded, and the quick discharge of the circuit is completed.
