In addition, mutual inductor temperature rise, insulation etc. other need to carry out in the test of short circuit grounding to Secondary Winding leading-out terminal, also usually adopt multiple conducting wires to be fixed together by the outlet terminal in requisition for short circuit and carry out short circuit, wire is connected on outlet bolt, complicated operation, and easily burn out wire due to larger current flowing, even burn out outlet box, there is very large technical matters.
Utility model content
The purpose of this utility model is to provide a kind of pouring current transformer test secondary short circuit device, adopts the insecure technical matters of wire short circuit outlet bolt short circuit in order to solve prior art Secondary Winding.
For achieving the above object, the utility model adopts following technical scheme:
Secondary short circuit device is used in pouring current transformer test, comprise at least two tagblocks for coordinating with the metal connection plate conductive contact of current transformer and the web joint for coordinating with described at least two tagblock conductive contacts, described each tagblock is corresponding with on web joint to be provided with and to intert for screw the connecting hole and perforation that have been fixedly connected with web joint by tagblock, connecting hole is located at the end of tagblock, perforation is located on web joint, described connecting hole is arranged along the length direction interval of web joint on web joint, the through hole that the outlet bolt on the metal connection plate of current transformer interts is provided with in the middle part of tagblock.
The conductive contact cooperation place of described web joint and tagblock is provided with the coat of metal, and the coat of metal is positioned on web joint or on tagblock.
Described tagblock is provided with boss, and the coat of metal is arranged on boss.
Described coat of metal institute plating is silver.
Advantageous Effects of the present utility model is: tagblock coordinates with the metal connection plate conductive contact of current transformer, web joint coordinates with at least two tagblock conductive contacts, tagblock is fixed on metal connection plate by outlet bolt, each tagblock interval on web joint length direction is connected on web joint, and then each Secondary Winding outlet terminal of short circuit, connected mode is reliable and stable.Simultaneously, the utility model adopts tagblock and web joint split to arrange, tagblock can be connected in relevant position on web joint, short circuit is carried out to the Secondary Winding outlet terminal of required short circuit, flexible to operation, when tagblock damages, pull down and change tagblock, do not need overall maintenance, cost-saving.
Further, the coat of metal is set in the cooperation place of web joint and tagblock, increases the current flowing ability of surface of contact.

Embodiment
Below in conjunction with accompanying drawing, a kind of embodiment of the present utility model is explained in detail.
A kind of specific embodiment 1 of the present utility model, as Fig. 1, secondary short circuit device is used in pouring current transformer test shown in 2, this secondary short circuit device comprises the tagblock 2 for coordinating with metal connection plate 7 conductive contact of current transformer, for the web joint 3 coordinated with tagblock 2 conductive contact, tagblock 2 end is provided with connecting hole, web joint 3 is provided with at least two of interting with Gong the screw 8 of connecting hole adaptation and bores a hole, the number of the present embodiment middle punch is 8, perforation is established along web joint length direction interval, in other embodiments, two and plural perforation can be set as required.Contiguous block 2 is connected on web joint 3 by screw 8.Tagblock 2 and web joint 3 all adopt aldary to make; Tagblock 2 is provided with boss 10, boss 10 upper surface is provided with silver coating 101, silver coating 101 coordinates with web joint 3 conductive contact, is provided with the through hole 9 for coordinating with outlet bolt 6 in the middle part of tagblock 2, and tagblock 2 can be fixed on outlet box 4 by outlet bolt 6.
As Fig. 3, shown in 4, outlet box 4 is connected with earth stud 5, outlet bolt 6, metal connection plate 7, metal base plate 12 is connected with bottom outlet box 4, in use, as shown in Figure 5, first tagblock 2 is connected to by screw 8 on the correspondence position of web joint 3, tagblock 2 is corresponding with the outlet bolt of required short circuit position to be arranged, the tagblock of different correspondence position can be connected in different tests, simultaneously, because tagblock 2 coordinates with metal connection plate conductive contact, Long-Time Service easily causes tagblock to damage, the tagblock 2 of corresponding damage is only needed to change during maintenance, do not need overall maintenance, cost-saving.Outlet bolt 6 is backed out, then secondary short circuit device is placed on outlet box 4, tagblock 2 is pressed on outlet box through through hole 9 by outlet bolt 6, tagblock 2 coordinates with metal connection plate 7 conductive contact, web joint 3 coordinates with silver coating 101 conductive contact, each tagblock links up by web joint 3, achieves outlet bolt 6 short circuit of required short circuit.Silver coating adds the electronics negotiability between web joint 3 contact position, avoids big current to burn out secondary short circuit device.
In different tests, the number being connected to tagblock on web joint can be adjusted as required, needing the corresponding position connecing short circuit block to connect tagblock, all carrying out short circuit by the outlet bolt 6 of Secondary Winding leading-out terminal all connecting tagblock 2 pairs of Secondary Winding leading-out terminals.In other embodiments, silver coating also can be arranged on web joint, and silver coating also can be replaced other coats of metal.
