Abstract
The invention relates to a DC contactor, which comprises a moving contact device and a static contact device. The moving contact device comprises a movable iron core. A feedback device is arranged under the movable iron core. The feedback device comprises an auxiliary contact upper sheet and an auxiliary contact lower sheet. The auxiliary contact lower sheet is provided with a first magnetizer, a second magnetizer and a reed switch arranged at the same side of the first magnetizer and the second magnetizer. The first magnetizer is provided with magnetic steel. When a contactor coil is powered on, the movable iron core moves upwards, a magnetic field loop is formed in the first magnetizer, the second magnetizer and the magnetic steel, and the generated magnetic field loop drives two reeds in the reed switch to contact to generate a contactor connection feedback signal; and when the contactor coil is powered off, the movable iron core restores, the magnetic field loop is blocked to form an open circuit, a magnetic field between the first magnetizer and the second magnetizer is lost, and the two reeds in the reed switch separate to generate a contactor disconnection feedback signal. The DC contactor can carry out synchronous feedback on work state of the contactor, so that the work state of the contactor can be monitored in real time.
