Description

Technical Field

[0001] The utility model relates to a polymerized crystalline silicon sheath for a cross arm of an electric pole, and belongs to the technical field of electric power transmission. Background Art

[0002] In power transmission, the conductor is supported by the crossarm installed on the pole. Insulators are installed on the crossarm of the pole to insulate the conductor from the crossarm of the pole. The conductor is fixed on the top of the insulator. When conducting electricity, although the conductor and the crossarm of the pole are separated by the insulator, when the voltage is high, the electric field lines pass through the air between the insulator and the crossarm of the pole, and electric flash occurs through the air. The high-energy electrons on the conductor jump down to the crossarm of the pole, which is also a conductor, which is easy to produce sparks, greatly affecting the safety of power transmission. Summary of the invention

[0003] The utility model aims to provide a polymer crystalline silicon sheath for a pole cross arm, so as to solve the technical defect in the prior art that when transmitting electricity, high-energy electrons on the wire fixed on the insulator jump onto the pole cross arm and easily generate sparks, thus affecting the safety of power transmission.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a polymer crystalline silicon sheath on the cross arm of the pole is made of polymer crystalline silicon material, including a sheath body, which is sleeved on the cross arm of the pole in a state of use. The sheath body includes a top plate, a left plate, a right plate and a bottom plate. The top ends of the left plate and the right plate are respectively fixedly connected to the left and right ends of the top plate, and the bottom plate is fixedly connected to the bottom ends of the left plate and the right plate. A connecting through hole running through the upper and lower surfaces thereof is provided on the top plate. In a state of use, the steel legs of the insulators installed on the cross arm of the pole pass through the connecting through hole, and a limiting groove is provided on the left plate and / or the right plate. In a state of use, a limiting piece is fixedly installed on the cross arm of the pole through the limiting groove to prevent the sheath body from moving along the length direction of the cross arm of the pole. The utility model is sleeved on a pole cross arm to wrap the pole cross arm, especially the upper surface of the pole cross arm facing the insulator side where the conductor is fixed. When high-energy electrons on the conductor fixed on the top of the insulator jump from the conductor to the pole cross arm, the sheath body separates the high-energy electrons from the pole cross arm, thereby avoiding sparks generated by the high-energy electrons jumping onto the pole cross arm and improving the safety of power transmission.

[0005] As a further improvement of the utility model, the bottom plate is composed of two long strip bottom plate units on the left and right, the left end of a bottom plate unit on the left is fixedly connected to the bottom end of the left plate, and the right end of a bottom plate unit on the right is fixedly connected to the bottom end of the right plate, and a long groove along the front-to-back direction is formed between the two bottom plate units on the left and right. The bottom plate in the utility model is composed of two parts, so the long groove formed between the two bottom plate units can be expanded by pulling the left plate and the right plate to the left and right sides when in use, so that the pole cross arm can enter the sheath body from the long groove at the bottom of the sheath body, thereby increasing the method of setting the utility model on the pole cross arm. Since the long groove is opened at the bottom of the sheath body, the upper surface of the pole cross arm is still covered by the sheath body, so the high-energy electrons fixed on the wire on the top of the insulator will not jump from the wire to the pole cross arm.

[0006] As a further improvement of the utility model, both the left and right plates are provided with limiting grooves, which extend downward through the bottom of the sheath body. The utility model has limiting grooves on both the left and right plates, so the sheath body can be limited from both sides of the sheath body, thereby improving the force uniformity of the utility model on the pole cross arm.

[0007] As a further improvement of the utility model, the top plate, the left side plate, the right side plate and the two bottom plate units are integrally formed. The connection strength of each part of the utility model is higher and the service life is longer.

[0008] To sum up, the beneficial effects of the utility model are as follows: the utility model is sleeved on the cross arm of the pole to enhance the insulation of the cross arm of the pole, and the high-energy electrons on the conductor jump to the sheath body instead of jumping to the cross arm of the pole, thereby avoiding the high-energy electrons jumping to the conductive cross arm of the pole to generate sparks and the potential safety hazard to power transmission.

The aperture of the connecting through hole 7 is slightly larger than the maximum diameter of the bottom threaded part of the steel foot 9 of the insulator 8. When in use, it is installed on the pole cross arm 2 The steel foot 9 of the insulator 8 passes through the connecting through hole 7 and is threadedly matched with the pole cross arm 2, so that the insulator 8 is fixedly installed on the pole cross arm 2. In this embodiment, limiting grooves 10 are provided on the left plate 4 and the right plate 5. In the use state, a limiting member 11 is fixedly installed on the pole cross arm 2 along the horizontal direction, and the limiting member 11 passes through the limiting groove 10 to prevent the sheath body 1 from moving along the length direction of the pole cross arm 2. The limiting member 11 in this embodiment can be a bolt, etc., with threaded holes provided on both sides of the pole cross arm 2. The bolts are threadedly matched with the pole cross arm 2 to fix the limiting member 11 to the pole cross arm 2. Since the limiting member 11 passes through the limiting groove 10, when in use, the limiting member 11 can block the sheath body 1 to prevent the sheath body 1 from moving along the length direction of the pole cross arm 2.

[0016] In this embodiment, the top plate 3, the left side plate 4, the right side plate 5 and the two bottom plate units 12 are preferably made in an integrally formed manner to maintain the overall connection strength of this embodiment.

[0017] When the present embodiment is used, the sheath body 1 is first sleeved on the pole cross arm 2 from one end, and then the limiting member 11 is passed through the limiting groove 10 and fixed to the pole cross arm 2 to limit the sheath body 1 in the horizontal direction.

In this embodiment, the widths of the left bottom plate unit 12 and the right bottom plate unit 12 are equal and are both smaller than the width of the long groove 13. Figure 1 and Figure 2 shown.

[0019] In this embodiment, the limiting groove 10 on the left side plate 4 extends downward and simultaneously penetrates the bottom end of the left side plate 4 and a bottom plate unit 12 on the left side, while the limiting groove 10 on the right side plate 5 extends downward and simultaneously penetrates the bottom end of the right side plate 5 and a bottom plate unit 12 on the right side, so that the limiting groove 10 penetrates downward the bottom of the sheath body 1. The structure of the rest of the present embodiment is the same as that of the embodiment 1, and the details can be referred to the embodiment 1, and this embodiment will not be repeated.

[0020] When the present embodiment is in use, the present embodiment can be fixed on the pole cross arm 2 in the manner of the embodiment 1, or the two bottom plate units 12 can be manually pushed in opposite directions so that the bottoms of the left side plate 4 and the right side plate 5 are bent and deformed in opposite directions, and the pole cross arm 2 is inserted into the sheath body 1 from the long groove 13 at the bottom of the sheath body 1, and then the sheath body 1 is loosened so that the sheath body 1 is sleeved on the pole cross arm 2, and then the sheath body 1 is limited in the horizontal direction by the limiting member 11, and finally the steel foot 9 of the insulator 8 is passed through the connecting through hole 7 and fixedly installed on the pole cross arm 2.
