Description

A cross-arm for distribution station

technical field

The utility model relates to the field of electric power transmission equipment, in particular to a cross arm for a power distribution station.

Background technique

The standardized station area is generally divided into two routes. Because of the influence of the gravity and tension of the conductors on both sides, a self-stay wire needs to be set up between the two poles of the platform to prevent the poles from tilting. 100mm ² steel strands are used for the pull wires, and 95mm ² overhead insulated wires are used for the high-voltage off-lines. However, the high-voltage lead wires will cross their own pull wires when they are off-line, resulting in insufficient safety distance in severe weather such as strong winds, which will affect the operation of the power grid later. cause a safety hazard.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the above-mentioned defects and provide a cross-arm for distribution stations.

In order to solve the above problems, the technical solution adopted in the utility model is:

A cross arm for a power distribution station, comprising a bracket, pole hoops are provided at both ends of the bracket, a number of support irons are provided on the support iron, insulators are provided on the support iron, and the ends of the insulators are provided with There is a cable hoop, and the cable hoop is rotatably connected to the insulator.

As an improvement: the pole hoop is a U-shaped hoop.

As an improvement: the support is provided with pad iron corresponding to the hoop of the electric pole.

As an improvement: the inner side of the pole hoop is provided with several transverse protrusions and longitudinal protrusions.

As an improvement: the support iron is trapezoidal, and the width of the support iron on the side close to the support is greater than the width on the side away from the support.

As an improvement: the bracket is made of angle iron.

Due to the adoption of the above technical scheme, the utility model can meet the safety distance between the self-drawing wire and the high-voltage offline wire under any conditions, and is simple to use, easy to operate and install, safe and effective.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Detailed ways

Example:

As shown in Figures 1, 2 and 3, a cross arm for a power distribution station includes a bracket 1, the bracket 1 is made of angle iron, pole hoops 2 are provided at both ends of the bracket 1, and the bracket 1 is also provided with a number of supporting irons 4, the supporting irons 4 are provided with insulators 5, and the ends of the insulators 5 are provided with cable hoops 6, and the cable hoops 6 and the insulators 5 are rotatably connected.

The pole hoop 2 is a U-shaped hoop, and the pole hoop 2 is connected to the support 1 through bolts.

The bracket 1 is provided with a pad 3 corresponding to the pole hoop 2, the pad 3 includes an arc surface, and the pad 3 and the pole hoop 2 form a ring shape.

The inner side of the pole hoop 2 is provided with a number of transverse protrusions 7 and longitudinal protrusions 8 to prevent the pole hoop 2 from loosening and sliding.

The support iron 4 is trapezoidal, and the width of the support iron 4 on the side close to the support 1 is greater than the width on the side away from the support 1 .

The support iron 4 adopts flat iron to make a trapezoidal structure and is welded on the cross-arm bracket, which not only saves material than the square structure, but also has a stable structure and is not easily deformed. Waste and old 4X40 flat iron can be used as the manufacturing material of the brace iron 4 .

When the utility model is in use, it is installed above the self-guy line, and the safety distance between the self-guy line and the high-voltage off-line can be controlled to the greatest extent. Due to the increased safety of equipment operation, the number of power outages and emergency repairs in severe weather such as strong winds has been reduced, labor has been reduced, the safe and stable operation of the power grid has been improved, and the reliability of power supply has been enhanced to truly reduce manpower and increase efficiency.

The utility model is easy to use and easy to install, the construction technology is improved, and the safety and stability of the line is improved. Avoid high-voltage off-line and short-distance line failures, ensure the stability of power transmission, and have outstanding social and economic effects.
