Description
Technical field
The utility model relates to instrument transformer technical field, particularly relates to a kind of detachable current transformer.
Background technology
The operation principle of current transformer is electromagnetic induction, is generally made up of the iron core closed and winding.Big current scaling transformation is mainly become standard small area analysis by the function of current transformer, to realize standardization, the miniaturization of measuring instrument, proterctive equipment and automatic control equipment.
At present, straight-through current transformer is made up of annular core, the secondary coil and insulation crust etc. be wound on annular core; But the current transformer of this form, comparatively time-consuming during installation, change current transformer very inconvenient.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of detachable current transformer, can conveniently install.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of detachable current transformer, comprise base, first semicircle pour mass, second semicircle pour mass, circular iron core, a winding, secondary winding and constraint ring, described first semicircle pour mass is arranged on described base, described second semicircle pour mass and described first semicircle pour mass connect, the joint of described first semicircle pour mass and described second semicircle pour mass is provided with locking device, described circular iron core with dock after described first semicircle pour mass and the shape adaptation of described second semicircle pour mass, described circular iron core is located in described first semicircle pour mass and described second semicircle pour mass, a described winding is formed in one the U-shaped structure of formula, described first semicircle pour mass and described second semicircle pour mass insulating case are located at the bend of a described winding, the two ends of a described winding are electric current incoming end, described secondary winding insulation is set around on described circular iron core, described constraint ring has elastic force, described constraint ring is positioned at the Huan Xinchu of described first semicircle pour mass and described second semicircle pour mass, the inwall of described first semicircle pour mass and described second semicircle pour mass is provided with multiple drag hook, described constraint ring is provided with the many pull bars for buckling with described drag hook, when described pull bar buckles on described drag hook, described constraint ring strains described pull bar towards the described ring heart.
Be different from the situation of prior art, the beneficial effects of the utility model are: by the pour mass of annular is divided into two semicircular parts, thus can conveniently install.
Accompanying drawing explanation
Fig. 1 is the structural representation of the detachable current transformer of the utility model embodiment.
Fig. 2 is the schematic perspective view of a winding of the detachable current transformer of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1, it is the structural representation of the detachable current transformer of the utility model embodiment.The detachable current transformer of the utility model embodiment comprises the semicircle pour mass 3 of base the 1, first semicircle pour mass 2, second, circular iron core 4, winding 5, secondary winding and a constraint ring 7.
First semicircle pour mass 2 is arranged on base 1, second semicircle pour mass 3 and the first semicircle pour mass 2 connect, the joint of the first semicircle pour mass 2 and the second semicircle pour mass 3 is provided with locking device 21, circular iron core 4 with dock after the first semicircle pour mass 2 and the shape adaptation of the second semicircle pour mass 3, circular iron core 4 is located in the first semicircle pour mass 2 and the second semicircle pour mass 3, a winding 5 is formed in one the U-shaped structure of formula, first semicircle pour mass 2 and the second semicircle pour mass 3 insulating case are located at the bend of a winding 5, the two ends of a winding 5 are electric current incoming end.As shown in Figure 2, winding 5 has the two ends 52 of bend 51 and connecting bending pars convoluta 51.
Secondary winding (not shown) insulation is set around on circular iron core 4, constraint ring 7 has elastic force, constraint ring 7 is positioned at the Huan Xinchu of the first semicircle pour mass 2 and the second semicircle pour mass 3, the inwall of the first semicircle pour mass 2 and the second semicircle pour mass 3 is provided with multiple drag hook 100, constraint ring 7 is provided with the many pull bars 110 for buckling with drag hook 100, when pull bar 110 buckles on drag hook 100, constraint ring 7 is towards ring heart tensile ties 110.
During detachable operation of current transformers, first semicircle pour mass 2 and the second semicircle pour mass 3 can be strained by constraint ring 7, the position of the first semicircle pour mass 2 and the second semicircle pour mass 3 is not changed, ensures that detachable current transformer normally works.
By the way, the detachable current transformer of the utility model embodiment adopts the first semicircle pour mass and the second semicircle pour mass to fix circular iron core, thus can conveniently install, and changes simple and convenient, simple operation.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
