Abstract
The invention discloses an auxiliary contact device for a high-voltage DC relay, and the device is used for monitoring whether a load terminal of a relay is connected or not. The device comprises a signal circuit and conductive elastic pieces. The conductive elastic pieces are disposed between the signal circuit and an iron core of the relay. When the iron core is slidingly connected with a big-current loop, the iron core drives the conductive elastic pieces to abut against two connection terminals of the signal circuit, thereby connecting the signal circuit. When the iron core slides and cuts off the big-current loop, the conductive elastic pieces automatically return to leave the connection terminals. The device provided by the invention can timely detect whether the relay works normally or not, effectively improves the safety and stability of the relay, and enables the maintenance of electric appliances to be more convenient.
