Description

Technical Field

[0001] The utility model belongs to the technical field related to electrical equipment, and particularly relates to a 110kV gapless composite jacket arrester installation structure. Background Art

[0002] Lightning arrester is a device used to protect electrical equipment from lightning strikes and overvoltage damage. Lightning arrester needs to be fixed on the pole tower or building through a bracket. The design of the bracket must ensure that the lightning arrester can be firmly installed in the predetermined position and allow enough space for the release of lightning energy. Therefore, the mounting structure is a necessary component for the stable operation of the lightning arrester, but it still has the following disadvantages in actual use:

[0003] When the arrester mounting structure is installed on the tower, it is installed on the cross arm. During the installation process, it is installed directly through the cross arm. However, during long-term use, the arrester will inevitably need to be replaced due to old age and other reasons. During replacement, after loosening the mounting bolts and other fasteners of the arrester, the arrester is directly separated from the mounting structure. The arrester is usually installed at a certain height above the ground. During the disassembly process, the arrester is easily caused to fall, affecting the safety of the arrester disassembly;

[0004] When the arrester mounting structure is installed on the tower, it needs to be installed with the high-voltage lead. During the installation process with the high-voltage lead, the wire ears on the lead are fastened to the structure on the arrester, but the installation positions of the lead and the arrester are usually fixed. When facing different installation positions, the installation operation is not convenient enough. Utility Model Content

By arranging the arrester body, L-shaped bracket, iron tower cross arm and rotating seat, the utility model solves the problem that the arrester installation structure is prone to operating errors when cooperating with the arrester to disassemble, causing the arrester to fall and creating a safety hazard, and the problem that the arrester is not convenient to connect to the high-voltage lead in different installation positions.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a 110kV gapless composite jacket arrester installation structure, comprising an arrester body, an L-shaped bracket, an iron tower cross arm and a rotating seat, a connecting disk is fixed at one end of the arrester body, an end of the connecting disk away from the arrester body is rotatably connected to the rotating seat, a mounting plate one is fixed at one end of the arrester body away from the connecting disk, a mounting plate two is arranged at a side of the mounting plate one away from the arrester body, an L-shaped bracket is fixed at one end of the mounting plate two away from the mounting plate one, an iron tower cross arm is arranged at one side of the L-shaped bracket, and when working, a lightning protection effect is provided by the arrester body, support is provided for the arrester body on the iron tower cross arm by the L-shaped bracket, connection is provided for the L-shaped bracket by the iron tower cross arm, and the high-voltage lead can be connected to the arrester body in the most suitable installation direction by the rotating seat.

[0008] Furthermore, screw rods 1 are fixed at four corners of the mounting plate 1 away from the arrester body, one end of the screw rod 1 away from the arrester body is threadedly connected with a nut, and the mounting plate is connected to the nut through the screw rod 1.

[0009] Furthermore, an auxiliary support plate is commonly fixed on the two inner walls of the L-shaped bracket, and the auxiliary support plate is arranged at an angle. The four corners in the second mounting plate are all provided with mounting holes, and the screw rod 1 is inserted into the mounting hole, and the nut is arranged on the outer side of the second mounting plate. The L-shaped bracket is auxiliary supported by the auxiliary support plate, and the screw rod 1 is inserted into the second mounting plate and then tightened, so that the lightning arrester body is installed on the L-shaped bracket.

[0010] Furthermore, two screw rods 2 are fixed on the outer surface of the vertical portion of the L-shaped bracket, and nuts are threadedly connected to the circumferential sides of the screw rods 2, and the L-shaped bracket is connected to the nuts via the screw rods 2.

[0011] Furthermore, two insertion holes are provided on one side of the tower cross arm close to the L-shaped bracket along the vertical center line, and the two screw rods are both inserted into the insertion holes, and the tower cross arm is movably connected to the screw rods through the insertion holes.

[0012] Furthermore, a mounting ear is fixed at the center of one end of the rotating seat away from the connecting disk, and a clamping bolt is threadedly connected to the rotating seat outside the mounting ear.

[0014] The utility model solves the problem that the arrester installation structure is prone to fall of the arrester and cause safety hazards by arranging the arrester main body, L-shaped bracket and iron tower cross arm. When the arrester main body is disassembled, the nut is loosened and then the arrester main body is held and pushed to release the arrester main body from the L-shaped bracket. When the arrester main body is disassembled, the arrester main body can be temporarily supported after loosening, thereby increasing the safety of the arrester main body disassembly operation, so that the arrester installation structure can better prevent the arrester from falling and causing safety hazards when the arrester is disassembled.

[0015] The utility model solves the problem of inconvenience in facing different installation positions when the lightning arrester is connected to the high-voltage lead by arranging a rotating seat. First, the clamping bolt is loosened, and then the high-voltage lead is fastened between fasteners such as wire ears and external mounting bolts. The rotating seat is rotated until the rotating seat and the connecting plate are in a suitable position of force balance, and the clamping bolt is rotated again. After the clamping bolt is rotated to be compressed between the connecting plate, the position between the lightning arrester body and the rotating seat is restricted, and the restriction of the rotating seat is completed, so that it is more convenient to face different installation positions when the lightning arrester is connected to the high-voltage lead.
