Description
Technical field
The utility model belongs to electric field experiment field, relates to mutual inductor on site test connection, especially a kind of mutual inductor test connection case.
Background technology
Mutual inductor on site testing equipment is primarily of compositions such as tester, pressure regulator, standard mutual inductor, tested mutual inductor, load boxs.Need more secondary line to connect during site test between these equipment, because equipment and instrument is many, test space is little, and it is more that secondary line connects cut-off point, easily causes wiring error generation security incident.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, scientific and reasonable, the mutual inductor test connection case of diverse in function.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of mutual inductor test connection case, it is characterized in that: comprise casing, roll, secondary line and case lid, casing is the bin-cube body structure of upper shed, and in casing upper end, spiral-lock has a case lid; In casing, horizontal cross is provided with a roll, and one end of this roll is provided with a pedestal, and pedestal is arranged in casing; The other end of roll stretches out that casing is outer and roll end outside casing is coaxially installed with a wheel disc; Roll is wound with many secondary lines, this secondary line is Biaxial, and the made wire hole of lower box is stretched out in one end of secondary line, and the other end of secondary line stretches out from wheel disc side.
And the secondary line on described roll is two or three, and every root secondary line adopts a kind of crust of different color respectively.
And handle is installed in case lid upper end, is fixed between case lid and casing by snap close.
And casing top is embedded with a box, this box be shaped with dividing plate just box be divided into multiple independently cell.
And the outer coaxial sleeve of the roll between wheel disc and casing is equipped with a set of cylinder, and leave gap between this sleeve and roll, the radial side of sleeve is shaped with wire hole.
And, wheel disc is fixed with handle.
Advantage of the present utility model and good effect are:
1, mutual inductor is tested secondary line and is divided Huang, green, red three kinds of color integrations in casing by this junction box, reduces test setup time, effectively improves wiring security.The subsidiary parts putting in order box of mutual inductor test connection case, can by the part containing such as sleeve pipe, chuck interior, and after reducing test, spare and accessory parts are lost.
2, this junction box is for the loaded down with trivial details situation design of mutual inductor on site test connection, effectively can reduce and connect/take-up the time, reduce dangerous point, improve site test security.

Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of mutual inductor test connection case, comprise casing 4, roll 10, secondary line 7 and case lid 1, be described with direction shown in accompanying drawing 1 for convenience of explanation, casing is the bin-cube body structure of upper shed, in casing, horizontal cross is provided with a roll 10, this roll is used for winding and deposits secondary line 7, and one end of this roll is provided with a pedestal 9, and pedestal is arranged in casing; The other end of roll stretches out that casing is outer and roll end outside casing is coaxially installed with a wheel disc 6, wheel disc is fixed with handle, rotates this wheel disc and roll can be driven to rotate;
Secondary line on roll is two or three, and every root secondary line adopts a kind of crust of different color to distinguish respectively.
Secondary line is Biaxial, the made wire hole of lower box is stretched out in one end of secondary line, the other end of secondary line stretches out from wheel disc side, one end connecting test instrument of secondary line during experiment, other end connection standard mutual inductor and tested mutual inductor, can carry out folding and unfolding by rotating roll to secondary line during test.
In casing 4 upper end, spiral-lock has a case lid 1, and handle 3 is installed in case lid upper end, is fixed between case lid and casing by snap close 2.
Casing top is embedded with a box, this box be shaped with dividing plate just box be divided into multiple independently cell, the accessories such as inserted sheet, exclusive clamps, sleeve pipe can be accommodated in box.
For the ease of rotating roll and protecting secondary line, the outer coaxial sleeve of the roll between wheel disc and casing is equipped with a set of cylinder 5, and leave gap between this sleeve and roll, the radial side of sleeve is shaped with wire hole.
Investigating existing mutual inductor on site experimental enviroment, by measuring tester in a variety of contexts to the general length of distance design wiring between standard mutual inductor and tester to mutual inductor secondary terminals, wire being fixed in junction box.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
