Description

Power plant closing relay housing

technical field

The utility model relates to the technical field of closing relays of power plants, in particular to a housing of closing relays of power plants.

Background technique

The relay is an electric 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. It has a control system and a controlled system. Interactive relationship, usually used in automatic control circuits, it is actually an automatic switch that uses small currents to control large currents, so it plays the role of automatic adjustment, safety protection, conversion circuits, etc. in power plants. When the closing relay is installed, it needs to be protected by the outer casing.
