Abstract

The invention discloses a lightning protection electromagnetic relay. The lightning protection electromagnetic relay is mainly composed of an electromagnetic relay body, a surge hysteresis unit, a shunting unit, a lightning early warning unit and a control unit; the relay body is used for controlling the breaking of an electric conduction loop; the surge hysteresis unit is used for delaying time for surge to arrive at the relay body; the shunting unit is used for dispersing surge current in the electric conduction loop; and the lightning early warning unit breaks the electric conduction loop before lightning occurs. Compared with the prior art, and according to the lightning protection electromagnetic relay of the invention, the whole electric conduction loop is broken through the relay, so that lightning surge can be effectively prevented from damaging electronic components in the electric conduction loop; and the lightning early warning unit is adopted, so that early warning against lightning can be performed in advance according to the surrounding environment of the relay body, and reaction time of the relay body can be prolonged, and the lightning surge can be prevented from damaging the electronic components in the electric conduction loop.

Description

technical field [0001] The invention relates to the technical field of relay lightning protection, more specifically, it relates to a lightning protection electromagnetic relay. Background technique [0002] The relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. Electromagnetic relays are generally composed of iron cores, coils, armatures, contact reeds, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil to generate an electromagnetic effect, and the armature will overcome the pulling force of the return spring and attract to the iron core under the action of electromagnetic attraction, thereby driving the armature to move The contact is closed with the static contact (normally open contact). [0003] For street...
