Abstract
The utility model relates to a multipurpose junction box for a secondary voltage drop test line, and the junction box comprises a rectangular box body. The bottom of the box body is fixedly equipped with a semi-spiral air plug. An outgoing cable of the air plug is divided into three four-core connection cables in the box body. The interior of the box body is fixedly equipped with three bearings with the same structures. The outer sides of the three bearings are fixedly equipped with three cable shafts which have the same structures. The three cable shafts are respectively wound by a four-core branching cable. One end of each four-core branching cable is connected with one end of a button switch, and the other end of the button switch is connected with the four-core connection cables. The other end of each four-core branching cable passes through a thread hole on the surface of the box body. Four core wires at end parts of the three four-core branching cables are respectively connected with a lockable sheath plug, a needle-shaped elastic sheath plug, and a sheath dedicated clamp. The junction box provided by the utility model carries out safe connection of wires according to different terminal strips in an on-site metering cabinet, and meets the requirements of on-site live testing.
Description
Technical field
The utility model belongs to mutual inductor on site experimental technique field, particularly the multiplex junction box of a kind of secondary voltage drop p-wire.
Background technology
The test of secondary voltage drop is the test for the voltage transformer (VT) of electric energy meter supply voltage and the secondary impedance value between electric energy meter, its method of testing is that the direct method of measurement does not namely have a power failure and tests, therefore, not only the dielectric level of equipment is had higher requirements, and the dielectric level of p-wire and joint is also had higher requirements.In secondary voltage drop test, secondary terminals row model specification is different, in order to carry out better under the premise that security is guaranteed site test, therefore designs a kind of different plug combination terminal box together, to solve field wiring problem, just seems very necessary.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and the multiplex junction box of a kind of secondary voltage drop p-wire is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
The multiplex junction box of a kind of secondary voltage drop p-wire, comprise rectangular box, base plane outside at casing is fixed with semi-spiral shape aviation plug, in the casing of aviation plug, four-core extraction cable separates three four-core stube cables in casing, at described box house, be fixedly mounted with three bearings that structure is identical, three bearing outsides are fixedly mounted with three cable shafts that structure is identical, in three cable shafts, be wound around respectively four-core separated time cable, four-core separated time cable one end is fastened on one end of the pushbutton switch at bearing middle part, the other end of pushbutton switch is connected with four-core stube cable, the other end of four-core separated time cable passes the through wires hole of tank surface, article three, on four heart yearns of four-core separated time cable end, connect and can lock sheath plug respectively, aciculiform flexible sheath plug and sheath exclusive clamps.
And, on the side of three four-core separated time cables of tank surface, be shaped with respectively plug groove, and on groove, twist tankage lid.
And, described in be fixed on bearing middle part its button of pushbutton switch be packed on box outer surface.
And the length of described three four-core separated time cables is 1 meter.
Advantage of the present utility model and good effect are
Safety requirements when 1, the utility model can carry out the satisfied live testing at the scene of safe socket line for different terminal rows in situ metrology cabinet.
2, this terminal box is furnished with safety key switch, has more further guaranteed the security of test.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
The multiplex junction box of a kind of secondary voltage drop p-wire, as shown in Figure 1, comprise rectangular box 1, base plane outside at casing is fixed with semi-spiral shape aviation plug 12, in aviation plug casing, four-core extraction cable 11 separates three four-core stube cables 10 in casing, at described box house, be fixedly mounted with three bearings 6, three bearing outsides are fixedly mounted with three cable shafts 7 that structure is identical, in three cable shafts, be wound around respectively four-core separated time cable 5, four-core separated time cable one end is connected to one end of the pushbutton switch 9 that is fixed on bearing middle part, the other end of pushbutton switch is connected with four-core stube cable, the other end of four-core separated time cable passes the through wires hole of tank surface, article three, on four heart yearns of four-core separated time cable end, connect and can lock sheath plug 4 respectively, aciculiform flexible sheath plug 8 and sheath exclusive clamps 13.
In concrete enforcement of the present utility model; side at three four-core separated time cables of tank surface is shaped with plug groove 3; for placing idle plug or the charged casing outside that is exposed to of exclusive clamps; when every group of plug or exclusive clamps are not used, just place it in groove; and on groove, twist tankage lid 2, form the further protection to plug or exclusive clamps.
In concrete enforcement of the present utility model; button on the described pushbutton switch that is fixed on bearing middle part can be at box house; the control of button can be, at the back side of casing, cabinet door is installed; after opening cabinet door, button is implemented to think control; button can certainly be packed on box outer surface directly and control, during in using three four-core separated time cables one, press corresponding button; for this cable powers up, other obsolete cable is power-off protection.
In concrete enforcement of the present utility model, the four-core separated time cable being wrapped in cable shafts can reclaim by opening cabinet door, also can adopt one end to be fixed on bearing middle part, the elastic force rotary cable axle that the other end is fixed on the wound spring in cable shafts reclaims four-core separated time cable.
In concrete enforcement of the present utility model, the length of described three four-core separated time cables is 1 meter.
