Abstract

The utility model belongs to transformer and assists the technical field using device, is specially transformer 35KV side outlet joint.For the existing problem of 35 kV-side of transformer outlet joint, butt joint is reformed, original bolt is longitudinally fixedly become cross bolts folder fix, the contact-making surface increasing wire and joint connects the generation decreasing conductor joint heating situation, and bolt is horizontal, no longer be positioned at outlet porcelain insulator inner, make replacing become easy.

Description

35 kV-side of transformer outlet joint
Technical field
The utility model belongs to transformer and assists the technical field using device, is specially transformer 35KV side outlet joint.
Background technology
Current 35 kV-side of transformer outlet joint used is bolted on after there is test, maintenance the situation of easy stripped thread again, conductor joint heating can be caused as joint does not tighten, affect equipment stable operation, cause a hidden trouble to electrical production, and bolt outlet porcelain insulator that is direct and transformer socket-connects, the bolt wanting to change stripped thread is very difficult.
Utility model content
The purpose of this utility model is for above-mentioned Problems existing and provides a kind of transformer 35KV side outlet joint.For the existing problem of 35 kV-side of transformer outlet joint, butt joint is reformed, original bolt is longitudinally fixedly become cross bolts folder fix, the contact-making surface increasing wire and joint connects the generation decreasing conductor joint heating situation, and bolt is horizontal, no longer be positioned at outlet porcelain insulator inner, make replacing become easy.
The technical solution of the utility model is:
A kind of transformer 35KV side outlet joint, is characterized in that, comprise connecting screw rod, connecting screw rod is provided with clamp nut, this inside, connecting screw rod one end is provided with coaxial screwed hole, and the other end of this connecting screw rod is fixed with terminal block, and described terminal block is provided with at least one wiring hole; The main body less than 2/3 of described connecting screw rod offers at least one expansion joint; Described connecting screw rod is used in being connected with transformer screw rod outlet terminal by screwed hole.
Feature of the present utility model also has:
Described terminal block is provided with 2-6 wiring hole, and preferably described terminal block is provided with 4 wiring holes.
Described expansion joint is 2-4 bar, and preferably described expansion joint is 3.
The width at described expansion joint is 2mm.
The beneficial effects of the utility model are: transformer 35KV side of the present utility model outlet joint, reduce the generation of bolt stripped thread situation, reduce the generation of conductor joint heating situation, and overall structure is simple, makes replacing become easy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Wherein, 1-terminal block, 2-wiring hole, 4-clamp nut, 5-screwed hole, 6-expansion joint, 7-connecting screw rod.
