The utility model discloses a counter for lightning protecting device, providing a digital statistic device which is simple and reliable operation and does not take place the false action and is able to adapt different circuit requirements. The technical proposal adopted is that the device is composed of a sampler and a counter; a rectifying circuit and a pulse processing circuit are sequentially connected between the sampler and the counter; the sampler is the sampling wire which twists around the pins of the lightning protection elements, and the two ends of the sampling wire are connected on the rectifying circuit; the sampling wire can twist around the pins of each lightning protection element with one turn connection in series; the lightning protection elements can adopt voltage dependent resistors. Compared with the prior art, the utility model can roundly reflect the products of lightning stroke occurred case in the three-phase ground adjustment and the three-phase zero adjustment circuits and also can detect the lightning stroke occurred case of the single-phase electric appliance, reliably saving data and having low manufacturing technology requirement.
