Abstract
The present utility model relates to the opening mechanism technology field, especially to a coil for opening. The coil is mainly composed of a central shaft, a magnet, a coil, adjusting nuts, a spring, the central shaft is adopted as a reference, an outer frame is arranged on the upper end of the central shaft, the coil and the magnet are arranged inside the outer frame, the coil is connected with a wire, the adjusting nuts are arranged on the top end of the outer frame, and the spring is wound on the central shaft segment below the outer frame. Through current induction, the iron core cross section and the number of wire diameter winding turns can be set according to a fitted mutual inductor, mutual inductor and an opening mechanism of the corresponding specification are fitted, thus the opening mechanism can be used for realizing fault opening without being supplied with power, the opening speed of a breaker can be quickened as the mechanism is also adopted as a control assembly, and sensitivity is enhanced.
Description
Technical field
The utility model relates to the brake separating mechanism technical field, relates in particular to a kind of separating brake coils special.
Background technology
Existing switching winding capacity is low, power is less, be difficult to help brake separating mechanism to realize quick acting switching-off, and need to can carry out the fault separating brake providing under the prerequisite of power supply, there is certain potential safety hazard, simultaneously existing switching winding is installed inconvenient, and the maintenance trouble, makes troubles for operative employee's regular job and maintenance.
The applicant has the deficiency that sees above-mentioned known traditional switching winding, adheres to research and innovation, excelsior spirit, utilizes professional eye and professional knowledge, proposes a simple and practical solution, therefore propose the application of this case.
Summary of the invention
The purpose of this utility model is the control assembly as brake separating mechanism, so that brake separating mechanism can be realized non-transformer fault separating brake, opening velocity is fast, a kind of separating brake coils special of separating brake sensitivity.
For achieving the above object, the utility model adopts following technical scheme: mainly comprise central shaft, magnet, coil, adjusting nut, spring, take central shaft as benchmark, the central shaft upper end arranges housing, coil and magnet have been installed in the housing, coil is connected with electric wire, and the housing top arranges adjusting nut, the central axis segment winding spring that housing is following.
Described coil is set core section and the wire diameter coiling number of turn by the electric current induction according to the instrument transformer that matches.
The utility model has the advantage of: cooperate the instrument transformer with dimension, so that brake separating mechanism in the situation that need not provide power supply can realize the fault separating brake, has been accelerated the opening velocity of circuit breaker as control assembly simultaneously, and improved sensitivity.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
See also shown in Figure 1, the utility model mainly comprises central shaft 1, magnet 3, coil 4, adjusting nut 5, spring 6, take central shaft 1 as benchmark, central shaft 1 upper end arranges housing 2, housing 2 interior coil 4 and the magnet 3 installed, coil 4 is connected with electric wire 7, and housing 2 tops arrange adjusting nut 5,1 section winding spring 6 of the central shaft of housing below 2.
During work, the instrument transformer that cooperates brake separating mechanism and dimension, switching winding need to be installed on the brake separating mechanism according to height by adjusting nut 5, core cross section and the wire diameter coiling number of turn that coil 4 is set according to the instrument transformer that matches, separating brake process coil 4 is by reverse current, so that brake separating mechanism is realized the quick acting switching-off tripping operation at very low energy.
Certainly, above diagram is the utility model better embodiment only, is not to limit the scope of application of the present utility model with this, therefore, everyly make equivalent change in the utility model principle and all should be included in the protection range of the present utility model.
