Description
Technical field
A kind of transmission line of electricity bar is the utility model is related to, 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 laying is outer, and most transmission line of electricity is still using aerial 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 wire and the change of stress condition lower wire position all need to meet it is 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 make horizontal stroke there is deviation to the flexibility of cross arm insulator
It is inadequate with the space crossed safe distance of opposite side circuit to carry on a shoulder pole insulator, and potential safety hazard be present.
Utility model content
In view of this, the purpose of this utility model is in view of the shortcomings of the prior art, there is provided is pacified suitable for high bending strength
Fill flexible cross arm insulator.
A kind of 220kV cross arm insulators of the utility model, it is characterised in that：A kind of 220kV cross arm insulators, its feature exist
In：Including clamp, connector, the diplopore fixed plate of two kinds of structure type, umbrella cover, plug, bolt assembly, described two structure shapes
The diplopore fixed plate of formula is crimped on plug by compression joint technique, and 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 utility model are：The utility model product supports the use with transmission line of electricity tubular shaped base, wire
Installation direction can carry out Arbitrary Rotation to bottom, its simple structure, easy for installation, can be widely popularized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is component diagram of the present utility model.
Embodiment
Such as Fig. 1, shown in Fig. 2：A kind of 220kV cross arm insulators, it is characterised in that：Including clamp (1), connector (3), two
The diplopore fixed plate (5,9) of kind structure type, umbrella cover (7), plug (8), bolt assembly (2,4), described two structure types
Diplopore fixed plate (5,9) is crimped on plug (8) by compression joint technique, the umbrella cover (7) by injection technique general injection into
On plug (8), the clamp (1) is fixed on connector (3) type 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 find suitable angle and fix, 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, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
