Abstract
The utility model relates to a 220 KV insulating high-altitude junction pole of a main transformer, being composed of a notch copper ring, a shrinking type drawing pole and a bottom end joint; the shrinking type drawing pole adopts a segmental, shrinking and drawing structure, the notch copper ring is fixedly arranged at the front end of the shrinking type drawing pole at one segment of the most front end, the bottom end joint is fixedly arranged at the end of the shrinking type drawing pole at one segment of the extreme end for connecting with a lengthening bar. The notch copper ring adopts a structure that a copper pipe is internally lined with steel bars, the strength is high and notch copper ring is not easy to be broken. The segmental shrinking type drawing pole adopts insulating material, and at least the pole body of the extreme upper end of the shrinking type drawing pole is made of the insulating material. The notch copper ring and the shrinking type drawing pole at the extreme upper end are connected by a screw thread. The 220 KV insulating high-altitude junction pole adopts a form that multiple segments of the drawing poles are combined and the operation is flexible, simple and convenient. In particular to being used, the 220 KV insulating high-altitude junction pole of a main transformer can be connected by adopting soft bare copper wires in an implementing way; that is, before in a short circuit, one end of a short-circuit wire is firstly connected on a casing flange grounding screw of a transformer, then connection is carried out one by one without climbing the bushing of the transformer.
Description
Technical field:
The utility model relates to the jointer of high pressure outside line, relates in particular to 220KV main transformer insulation high-altitude wiring bar.
Background technology:
The height outside line forever that overhead type is provided with, wiring position is higher apart from ground, and operating personnel will use special equipment when implementation and operation, arrive high empty position and carry out work high above the ground.The high-altitude operating environment such as to rock abominable, dangerous and inefficiency.
The utility model content:
The purpose of this utility model is; overcome the deficiencies in the prior art part; a kind of 220KV main transformer insulation high-altitude wiring bar is provided; use more piece pull insulating bar to make junction pole; flexible operation is easy; can satisfy the requirement of strength of regulation, and play the injury that the protection staff avoids being subjected to induced voltage, security performance is good.
220KV main transformer insulation high-altitude wiring bar described in the utility model, include the gap type copper ring, contract and form through formula pumping rod and following end connector, it is said that to contract through the formula pumping rod be main component of the present utility model, adopt merogenesis to contract through the structure of pull, foremost one the joint contract through the front end of formula pumping rod, be set with the gap type copper ring; Contracting of least significant end one joint through the end of formula pumping rod, be set with down end connector, be used for being connected with extension bar.Be arranged on the gap type copper ring on junction pole top, adopt the structure of copper tube inner lining steel bar, intensity height, not frangibility.Said segment type contracts and adopts insulating material through pumping rod, and contracting at least topmost made through the shank portion employing insulating material of formula pumping rod.The gap type copper ring adopts screwed connection with contracting of the top through the formula pumping rod.220KV main transformer insulation high-altitude wiring bar described in the utility model adopts the combined form of more piece pull insulating bar, and flexible operation is easy, can satisfy requirement of strength, and plays the injury that the protection staff avoids being subjected to induced voltage, and security performance is good.
220KV main transformer insulation high-altitude wiring bar described in the utility model, overall structure is simple, and is easy for operation.During concrete the use, can adopt soft bare copper wire to implement to connect, that is: before short circuit, short-circuit line one end is connected on earlier on the bushing shell for transformer flange ground connection screw, by articulating mutually, need not to climb bushing shell for transformer then.
