Abstract
A bidirectional contactor comprises a contactor which mainly comprises a casing (1), a coil (2), a fixed iron core (3), a moving iron core (4), a moving contact (5), a fixed contact (6), an offsetting spring (7), and an auxiliary normal open-and-close contact (12), and additionally comprises a coil (8), a fixed iron core (9), a fixed contact (10), an offsetting spring (11), and an auxiliary normal open-and-close contact (13). The utility model has the advantages that the bidirectional contactor can substitute two contactors in the obverse-and-reverse rotation of a motor and the star-delta reduced-voltage starting of a motor, thereby cutting down the cost, reducing the fitting space of a power distribution cabinet, simplifying the device installation, and avoiding the line-to-line short-circuit in the case that the utility model gets out of order and carries out false operation.
Description
Technical field
The utility model relates to appliance field.Relate in particular to contactor.
Background technology
At present, it can only use commercially available contactor as single-way switch, all is to use 2 contactors to finish for the rotating of motor and the star one leg-of-mutton reduced-voltage starting of motor, but in case breaks down and will misoperation occur and cause phase fault.
Summary of the invention
The purpose of this utility model provides a kind of two-way contactor at the above-mentioned deficiency of existing contactor exactly, comprise contactor, contactor is mainly by housing 1, coil 2, static iron core 3, moving iron core 4, moving contact 5, fixed contact 6, back-moving spring 7 and auxiliary normally-open normally-close contact 12 are formed, coil 2, static iron core 3 is installed in the housing 1, moving contact 5 is installed on the moving iron core 4 by insulating support, moving iron core 4 is movably arranged in the housing 1, corresponding with static iron core 3, coil 2 is between static iron core 3 and moving iron core 4, fixed contact 6 is installed on housing 1, back-moving spring 7 one ends withstand on the moving iron core 4, the other end withstands on the coil 2, the fixed contact of auxiliary normally-open normally-close contact 12 is installed on the housing, and moving contact is installed on the moving iron core 4 by insulating support; It also has coil 8, static iron core 9, fixed contact 10, back-moving spring 11 and auxiliary normally-open normally-close contact 13, coil 8 and static iron core 9 are installed on the housing 1, static iron core 9 is corresponding with moving iron core 4, coil 8 is between static iron core 9 and moving iron core 4, and fixed contact 10 is installed on the housing 1, and is corresponding with moving contact 5, back-moving spring 11 1 ends withstand on the moving iron core 4, the other end withstands on the coil 8, and the fixed contact of auxiliary normally-open normally-close contact 13 is installed on the housing, and moving contact is installed in moving iron core 4 by insulating support
The utility model has the advantages that: adopt this two-way contactor can replace 2 contactors for the rotating of motor and the star one leg-of-mutton reduced-voltage starting of motor, reduce expenses, reduce the installing space of power distribution cabinet, the equipment that simplifies is installed, and in case breaks down and can misoperation not occur and cause phase fault.Because its moving iron core 4 is public, can only make progress adhesive or adhesive downwards, the two can only be one.When coil 2 and coil 8 were switched on simultaneously, because the model of two coils is identical, the electromagnetic force of generation was identical, and moving 4 of iron cores remain on the former resting position, so use very safe.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
Manufacturing process of the present utility model is with now contactor is the same, just increase coil 8, static iron core 9, fixed contact 10, back-moving spring 11 and auxiliary normally-open normally-close contact 13 on the basis of existing contactor, the coil 8 of increase, static iron core 9, fixed contact 10, back-moving spring 11 and auxiliary normally-open normally-close contact 13 are the same with auxiliary normally-open normally-close contact with coil, static iron core, fixed contact, the back-moving spring of existing contactor.Coil 8 and static iron core 9 are installed on the housing 1, and static iron core 9 is corresponding with moving iron core 4, and coil 8 is between static iron core 9 and moving iron core 4, fixed contact 10 is installed on the housing 1, corresponding with moving contact 5, back-moving spring 11 1 ends withstand on the moving iron core 4, and the other end withstands on the coil 8.The fixed contact of auxiliary normally-open normally-close contact 13 is installed on the housing, and moving contact is installed on the moving iron core 4 by insulating support.
