Background
The contactor is an electric appliance which utilizes a coil to flow current to generate a magnetic field in industrial electricity to close a contact so as to control a load. 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 has a fault, the conventional contactor loses the power source of the action, so that the main contact cannot act. At the moment, if a fire disaster happens, the fire pump cannot be started, and the failure of the fire-fighting system is caused. Therefore, a mechanical emergency starting device for controlling the contactor appears in the market, and the mechanical emergency starting device is mainly used for starting the fire pump in an emergency by personnel with management authority when a controller of the fire pump cabinet or a contactor secondary circuit for controlling the fire pump fails, or in other occasions requiring mechanical emergency starting of the fire pump in emergency.
