Abstract
The utility model relates to a holding pole thread jointing clamp for a transformer, which is characterized in that a holding pole thread head is arranged on one end of a connecting plate, a clearance is arranged on the tip of the holding pole thread head, a fastening lug is arranged on each side of the clearance, and a through hole is arranged on the middle of the two fastening lugs. A transverse fixing piece is arranged on the other end of the connecting plate, the two ends of the fixing piece are separately fixed on the connecting plate by bolts, and a corresponding groove is arranged on the middle of the fixing piece and the connecting plate. The utility model has the advantages that the bolt hole of the holding pole thread head is screwed into a high tension bushing of the transformer and a screw bolt of the low tension bushing, a bolt is got through the through hole of the fastening lug and screwed tightly, the bolt hole is tightly held on the bushing screw bolt, the clearance between the two is eliminated, the contact area is increased, the contact electric resistance is decreased, and the normal operation of the electrical supply system is ensured.
Description
Technical field
The utility model relates to a kind of transformer pole screw thread binding clip, is used for high-voltage line and low-voltage line and the bushing of transformer and being connected of low-tension bushing end.
Background technology
Prior art adopts common terminal block (sheet) to be enclosed within on the screw rod of transformer high-voltage sleeve pipe and low-tension bushing and is fastening with nut.Its shortcoming is that contact exists the gap, and contact area is little, and contact resistance is big, sometimes even can produce spark, influences the normal operation of electric power system.
Summary of the invention
The purpose of this utility model just provides a kind of transformer pole screw thread binding clip, has the gap to solve the contact that prior art exists, and contact area is little, and contact resistance is big, sometimes even can produce spark, influences the problem of the normal operation of electric power system.
The technical solution of the utility model is: the end at a terminal block is provided with the pole thread head, is provided with the gap in the end of this pole thread head, respectively is provided with a fastening lug on the both sides in this gap, is provided with through hole in the central authorities of these two fastening lugs; The other end at described terminal block is provided with horizontal solidus sheet, and the two ends of this solidus sheet respectively and be fixed by bolts on the terminal block are provided with groove opposite in the central authorities of this solidus sheet and terminal block.
The utility model has the advantages that: the screw of its pole thread head screws on the screw rod of transformer high-voltage sleeve pipe and low-tension bushing, the through hole that passes fastening lug with screw screws, make screw hold the sleeve pipe screw rod tightly, eliminated the gap that exists between the two, increased contact area, reduce contact resistance, guaranteed the normal operation of electric power system.

Embodiment
Referring to Fig. 1～Fig. 5, the end that the structure that the utility model is used for the embodiment that bushing connects is included in a terminal block 4 is provided with pole thread head 1, be provided with gap 11 in the end of this pole thread head, respectively be provided with a fastening lug 2 on the both sides in this gap 11, central authorities at these two fastening lugs are provided with through hole, pass bolt 3 during use.The other end at described terminal block 4 is provided with two horizontal solidus sheets 8, the two ends of this solidus sheet 8 also are fixed on the terminal block 4 with bolt 7 respectively, central authorities at this solidus sheet 8 and terminal block 4 are provided with groove opposite 9, and with the approximate round mouth of relative formation, clamping wire 12 in round mouth.
Referring to Fig. 6～Figure 10, the difference that the utility model is used for the embodiment that the structure of the embodiment that low-tension bushing connects is connected with above-mentioned bushing is that described terminal block is divided into two section 4 and 6, with bolt 5 two sections terminal blocks is fixed together.It is that the spacing of low-tension bushing of transformer is less that terminal block is divided into two sections reason, when being installed, terminal block needs rotation, the entire length of terminal block just can not be installed greater than the spacing of low-tension bushing, so be divided into two sections, will have one section 4 of pole thread head 1 and again another section terminal block 6 is connected with 4 after installing.Other structures are identical with a last embodiment, repeat no more.
Around forming, make by aluminium by other parts of the terminal block outside copper layer 10 by copper layer 10 for the screw of pole thread head 1 of the present utility model, adopts casting method to make.Also can all be made of copper.
The utility model screws in the screw of pole thread head 1 on the screw rod 13 of the bushing 15 (referring to Fig. 5) of transformer 16 and low-tension bushing 17 (referring to Figure 10) when using, and the through hole that passes fastening lug 2 with screw 3 screws.Also can safety guard 14 be installed in the outside of binding clip, functions such as that safety guard 14 has is anti-electricity-theft, protection against electric shock, waterproof and dustproof, snow defence frost.
