Abstract
A kind of suspension insulator string.The composite rod insulator unit of grading ring is provided with including both ends, it further include another suspended porcelain insulator unit, the ball-and-socket of suspended porcelain insulator unit is connect with the bulb of composite rod insulator unit, the composite rod insulator unit accounts for the long 2/3-4/5 of total string, and the suspended porcelain insulator unit accounts for the long 1/3-1/5 of total string.Overcome the problems, such as unreasonable structure of the existing technology and local electric field strength is larger.
Description
Technical field
The invention belongs to electrical equipment technical fields, and in particular to a kind of extra-high-voltage alternating current suspension insulator string.
Background technique
For the insulator of extreme high voltage grade, it is domestic it is existing be whole branch stick row suspension composite structure.It is existing
There is technology the problem is that unreasonable structure and local electric field strength is larger, low, nothing which results in starting corona voltages
Line electrical interference is larger, surface of composite insulator galvanic corrosion damage is reinforced, service life is affected insufficient producing of being reduced with reliability
It is raw.
Summary of the invention
The purpose of the present invention is to provide a kind of suspension insulator string, with overcome unreasonable structure of the existing technology and
The larger problem of local electric field strength.
It is of the existing technology to overcome the problems, such as, the technical scheme is that including a rod insulator compound inslation
Subelement, both ends are provided with grading ring, further include another suspended porcelain insulator unit, the ball-and-socket of suspended porcelain insulator unit
It is connect with the bulb of composite rod insulator unit, the composite rod insulator unit accounts for the long 2/3-4/ of total string
5, the suspended porcelain insulator unit accounts for the long 1/3-1/5 of total string.
Above-mentioned suspended porcelain insulator unit is porcelain long rod insulator.
Above-mentioned suspended porcelain insulator unit is suspension disc insulator.
Compared with prior art, the invention has the advantages that structure of the invention is reasonable, the electric field at high-voltage end can reduced
Intensity, improve field distribution while, high voltage field intensity region is undertaken with the good porcelain insulator of electric strength, in, existing fringing field it is strong
Degree area is undertaken with organic composite insulator, and has grading ring, greatly reduces the corona possibility of surface of composite insulator,
So as to effectively inhibiting the galvanic corrosion on organic composite insulator surface to damage, the service life of integral insulation substring and reliable is improved
Property.The present invention is suitable for exchanging the electric insulation of overhead transmission line pendency or strain insulator conducting wire and is mechanically fixed, especially suitable for
Voltage rating is 1000kV, and frequency is no more than 100Hz system.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Specific embodiment
The present invention is described in detail with reference to the accompanying drawing.
Referring to Fig. 1, the present invention includes that a both ends are provided with the composite rod insulator unit 1 of grading ring 4 and another
One suspended porcelain insulator unit, which is porcelain long rod insulator 2, and both ends are also equipped with grading ring
4.The ball-and-socket 6 of porcelain long rod insulator 2 is connect with the bulb 5 of composite rod insulator unit 1.Described rod insulator is multiple
It closes insulating subunit 1 and accounts for long 2/3 of total string, described porcelain long rod insulator 2 accounts for long 1/3 of total string.
In use, composite rod insulator unit 1 is located at ground side, described suspended porcelain insulator unit, which is located at, is led
Line side.
