Abstract
The utility model relates to a current transformer secondary line encapsulation instrument, including casing (1), its characterized in that: there are one open -ended recess (8) in casing (1) central authorities, recess (8) bottom fixed mounting short circuit piece (2), it has four entrance hole (7) to open on casing (1) in the bottom of closing on recess (8), the foot of entrance hole (7) remains basically stable with the upper surface of short circuit piece (2), ensure that the threading is convenient, the middle and upper position of recess (8) is put and is inlayed mounting (3) in casing (1), four align to grid screw (4) are gone up in mounting (3), screw (5) penetrate in screw (4), crimping piece (6) are installed on screw (5) top, the business turn over vertical motion of screw (5) can be followed in crimping piece (6), a A for inciting somebody to action current transformer, B, C, N looks wire compresses tightly in order to realize the short circuit on short circuit piece (2). The utility model discloses effectively improved constructor construction factor of safety, guaranteed that construction process is up to standard.
Description
Technical field
The utility model belongs to power engineering instrument device technique field, particularly relates to Current Transformer Secondary line encapsulation tool in a kind of transformer station.
Background technology
At present, when comprehensive automation system of transformer substation is transformed, all need synchronously the old terminal board in arrangement terminal case place and secondary cable to be changed, and because of construction period, need to carry additionally interim kilowatt-hour meter to measure electric flux, therefore, the current terminal row drawn in the secondary cable and terminal box thereof of current transformer can not remove immediately, this carries out short circuit process with regard to needing to the non-metering secondary line drawn from current transformer place, and way was direct short circuit on current terminal row in terminal box in the past.But apply this kind of way, when workmen carries out wiring to secondary cable in terminal box, touch the current terminal do not removed arrange and form security threat to workmen very easily by mistake, and because current terminal row together being removed replacing with other terminal boards, the wiring difficulty of secondary cable in terminal box will certainly be caused to strengthen and cause wiring technique to meet construction reference.Therefore, design is a kind of can ensure workmen's safety when carrying out secondary cable wiring in terminal box, can ensure that again the Current Transformer Secondary line encapsulation tool of construction technology is necessary.
Summary of the invention
The purpose of this utility model is to solve the transformation of current transformer substation integrated system because there is security threat when current terminal row cannot remove immediately and cause workmen's wiring in terminal box, and wiring technique can be caused not reach the drawback of construction reference, invention has made a kind of Current Transformer Secondary line encapsulation tool.Realizing the technical scheme that the purpose of this utility model takes is: a kind of Current Transformer Secondary line encapsulation tool, include housing, it is characterized in that: there are the groove of an opening in housing central authorities, bottom portion of groove fixed installation short circuit sheet, on housing, four entrance holes are had in the bottom closing on groove, the foot of entrance hole and the upper surface of short circuit sheet remain basically stable, guarantee that threading is convenient, fixture is inlayed in the position, middle and upper part of housing further groove, evenly distributed four screws on fixture, screw penetrates in screw, the top of its screw 5 is provided with crimp, crimp can move both vertically with the turnover of screw, for by current transformer A, B, C, N phase conductor is pressed on short circuit sheet to realize short circuit.After choosing and guaranteeing that wire compresses by crimp of position inlayed by fixture, the nut of screw still inside grooves in the housing.
The utility model structure is simple, easy to make, but practicality is high, effectively can solve the transformation of current transformer substation integrated system because there is security threat when current terminal row cannot remove immediately and cause workmen's wiring in terminal box, and wiring technique can be caused not reach the problem of construction reference, effectively can improve workmen's construction safety coefficient, ensure that construction technology is up to standard.

Embodiment
As shown in the figure: a kind of Current Transformer Secondary line encapsulation tool, include housing 1, it is characterized in that: there are the groove 8 of an opening in housing 1 central authorities, short circuit sheet 2 is fixedly mounted bottom groove 8, on housing 1, four entrance holes 7 are had in the bottom closing on groove 8, the foot of entrance hole 7 and the upper surface of short circuit sheet 2 remain basically stable, guarantee that threading is convenient, fixture 3 is inlayed in the position, middle and upper part of housing 1 further groove 8, evenly distributed four screws 4 on fixture 3, screw 5 penetrates in screw 4, the top of screw 5 is provided with crimp 6, crimp 6 can move both vertically with the turnover of screw 5, for by current transformer A, B, C, N phase conductor is pressed on short circuit sheet 2 to realize short circuit.After choosing and guaranteeing that wire compresses by crimp 6 of position inlayed by fixture 3, the nut of screw 5 still groove 8 is within the case 1 inner.
During use, screw 5 is outwards back-outed, guarantee between crimp 6 and short circuit sheet 2, have enough spaces to hold the secondary current line of current transformer, by current transformer A, B, C, N phase current wire penetrate in entrance hole 7 successively, make it the below that the end of a thread is in crimp 6, screw 5 is screwed into, crimp 6 is made every wire of current transformer to be pressed on encapsulation short circuit short circuit sheet 2 realizing Current Transformer Secondary line, after encapsulation short circuit, this encapsulation tool tape-stripping is fixed on the tank wall of terminal box or does not hinder the place of constructing in terminal box.
Claims (2)
