Grid-side filter capacitor double-contact parallel contactor of wind generating set

The utility model belongs to the field of double-contact parallel contactors, and particularly relates to a double-contact parallel contactor for a grid-side filter capacitor of a wind generating set, which comprises a contactor, a mounting seat is contacted on the contactor, a clamping groove is arranged in the mounting seat, a limiting mechanism is contacted on the contactor, a connecting sleeve is fixedly connected on the contactor, and the clamping groove is arranged in the clamping groove. A filter screen is fixedly connected in the connecting sleeve, and an anti-blocking mechanism is arranged in the connecting sleeve. By designing parts such as a motor, a rotating column, a first bevel gear, a second bevel gear, a rotating rod and a bearing, airflow enters a contactor to dissipate heat of the contactor, dust in the airflow is filtered by a filter screen, the contactor is cooled, the service life of the contactor is prevented from being shortened, the motor is started, the motor drives the rotating colum
