Described air switch is connected with frequency converter;
Described contactless switch is connected with frequency converter, air switch and main control microcomputer plate respectively;
Described main control microcomputer plate also connects phase sequence relay and connection terminal, described connection terminal is made up of with the power connection terminal that is used to be connected external power supply the control conection terminal that is used to connect external control component, and voltage transformer is connected to external power supply by the power connection terminal;
Described voltage transformer is by being used to inner each parts of control housing that the big voltage transformer of power is provided and being used to that each parts provides the small transformers of power to form in the hoistway.
Preferably, described control housing cabinet top is equipped with ventilation heat abstractor, and braking resistor is placed in the ventilation heat abstractor.
Preferably, the installation direction of all elements is consistent in the described control housing.
The beneficial effects of the utility model are: after frequency converter is connected to master control microcomputer plate by magnet ring, be connected with external motor by the takeoff output cable again, the high order harmonic that can avoid the takeoff output cable to discharge is disturbed the main control microcomputer plate, reduces the fault of microcomputer plate, improves the safety of elevator; The installation direction of all components and parts in the described control housing all is consistent, can realize unidirectional maintenance, has improved the efficient of maintenance, has reduced maintenance cost; Moreover, the utility model structure design compactness, the size of having dwindled control housing has greatly reduced the influence of layout to decorating outside the Room of control housing.
