Description
Technical field
The present invention relates to a kind of transmission line of electricity bar, especially a kind of 220kV cross arm insulators.
Background technology
With developing rapidly for China's electric utility, in transmission line construction, transformation, except part transmission line of electricity is changed to electricity
Cable lays outer, and most transmission line of electricity is still using built on stilts form.Aerial transmission line of electricity is maked somebody a mere figurehead by transmission pole, wherein
Under fixation and various meteorological conditions to the installation site of the wire and position of stress condition lower wire change all needs to meet electric
Regulatory requirements, and the safe distance of transmission line of electricity and installation site are more one of stubborn problems in engineering design.In 220kV
The use of cross arm insulator is particularly significant when transmission line of electricity is installed, the transfer wire used in different transmission lines of electricity and connection
Structure type it is also just different, the adjustable of this situation lower clamp is particularly important, and high air line angle is difficult to adjust, to peace
Dress personnel cause very big influence.And if good general can not cause side to there is deviation to the flexibility of cross arm insulator, make horizontal stroke
Carry on a shoulder pole insulator inadequate with the space crossed safe distance of opposite side circuit, and there is potential safety hazard.
The content of the invention
In view of this, the purpose of the present invention is that there is provided install spirit suitable for high bending strength in view of the shortcomings of the prior art
Cross arm insulator living.
A kind of 220kV cross arm insulators of the present invention, it is characterised in that：A kind of 220kV cross arm insulators, it is characterised in that：
Including clamp, connector, the diplopore fixed plate of two kinds of structure type, umbrella cover, plug, bolt assembly, described two structure types
Diplopore fixed plate be crimped on by compression joint technique on plug, the umbrella cover is by injection technique integral injection molding in plug
On, the clamp is fixed on connector by bolt assembly, and the connector is arranged on diplopore fixed plate by bolt assembly
On.
Further, the plug is diameter 80mm, length 2350mm ECR acid-resistant and anti-high-temperature plugs, can bear 10kN
Bending strength.
The further connector is L-shaped, and its number can be actually needed according to circuit and be adjusted.
Further, the clamp uses V-shaped groove structure.
The beneficial effects of the invention are as follows：Product of the present invention is supported the use with transmission line of electricity tubular shaped base, wire installation direction
Arbitrary Rotation can be carried out to bottom, it is its simple structure, easy for installation, it can be widely popularized.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is component diagram of the invention.

Diplopore fixed plate (5,9) is crimped on plug (8) by compression joint technique, the umbrella cover (7) by injection technique general injection into
Type is on plug (8), and the clamp (1) is fixed on connector (3) by bolt assembly (2), and the connector (3) passes through spiral shell
Bolt assembly (4) is arranged in diplopore fixed plate.
Plug (8) is diameter 80mm, length 2350mm ECR acid-resistant and anti-high-temperatures plug (8), and the bending that can bear 10KN is strong
Degree, connector (3) is L-shaped, and its number can be actually needed according to circuit and be adjusted, and clamp (1) uses V-shaped groove structure, by horizontal stroke
The diplopore fixed plate (9) of load is packed into transmission line of electricity tubular shaped base, according to the diplopore scene in diplopore fixed plate (9) on base
Perforate, conveniently finds suitable angle and fixes, and wire is placed in clamp (1), locking bolt components (4), bolt assembly (4)
Tightening up and loosening can be adjusted according to field wires diameter.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to skill of the invention
Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this
Among the right of invention.
