Example Embodiment
[0010] Example: such as figure 1 As shown, the lightning arrester counter remote clearing device is composed of a current generator 2 installed on the upper part of the insulating rod 1 and a power supply 5 connected to the current generator 2. The current generator 2 includes a power switch, a signal generator, an output amplifier, and a current output terminal. The signal generator is connected to a power source 5 and a remote control circuit board through a wire 4, and the current output terminal is the electrode 3. The signal generator can use existing technology, for example: it is composed of an LC oscillator and a buffer, the inductance in the oscillating circuit of the LC oscillator is composed of a magnetic core, a primary coil and a secondary coil, the primary coil and The capacitor forms an LC oscillating circuit. One end of the secondary coil is grounded, and the other end is connected to the fixed contact of the changeover switch. The movable contact of the changeo...
