摘要
Abstract
Magnetic latching relay which has switch function in the electronic Watt-hour meter plays an important role in the power filed.But the trip under the condition of the large current can cause the injury of the magnetic latching relay contactor.Contactor can’t be open normally after multiple injury, and even cause fire.Combined with the actu-al load situation and the operating principle of the energy meter, this paper presents a soft arc suppression design means to achieve the zero current crossing trip and to protect the magnetic latching relay from injury caused by large current.Through comparative experiments, the zero crossing trip has the advantage of protecting magnetic latching re-lay in a better way and reduces the damage to the lower level.关键词
