Background
The contactor is widely applied to a control circuit of a fire pump, and under the normal condition of the control circuit, after a coil of the contactor is electrified, current flowing through the coil generates a magnetic field to enable an armature to attract an iron core and drive a main contact of the contactor to be closed, and a main circuit is connected. When the coil of the contactor is powered off, the current flowing through the coil disappears, the electromagnetic attraction of the armature also disappears, and the armature is released under the action of the release spring, so that the main contact of the contactor is separated, and the main circuit is disconnected.
The motive force for contactor action is due to the magnetic field generated by the passage of current through the cored coil. Therefore, under the condition that the controller or the control circuit fails, the conventional contactor loses the power source of action, so that the main contact cannot act, and at the moment, if a fire disaster happens, the fire pump cannot be started, so that the failure of a fire protection system is caused.
