Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a pollution-resistant disc-shaped suspension porcelain insulator for high-voltage lines. Background Art

[0002] Insulators are special insulating components used on electric poles or electric towers. Since insulators are exposed outdoors, their surfaces are contaminated and polluted by industrial and natural pollutants for a long time. When the pollutant layer on the surface is damp, the insulation resistance decreases and the leakage current increases, which leads to flashover accidents and brings serious harm to the high-voltage transmission and transformation system of the power grid.

[0003] When using the existing pollution-resistant disc-shaped suspension porcelain insulators, multiple individual insulators are generally connected by bolts to form a longer insulator group for use. Connecting the insulators by bolts requires the use of many tools, which is troublesome to operate. Therefore, we have introduced a new pollution-resistant disc-shaped suspension porcelain insulator for high-voltage lines. Utility Model Content

[0004] The main purpose of the utility model is to provide a pollution-resistant disc-shaped suspension porcelain insulator for high-voltage lines, which can effectively solve the problems in the background technology.

[0007] Preferably, a connecting slot is provided in the middle of the lower end of the connecting rod, four connecting card slots are provided in the lower inner surface of the connecting slot, and a first external connection hole is provided on the upper left side and the upper right side of the inner surface of the connecting slot.

[0008] Preferably, four connection blocks are fixedly connected to the lower portion of the outer surface of the connection pipe, and second external connection holes are provided on the upper left side of the inner surface of the connection pipe and on the upper right side of the inner surface.

[0009] Preferably, the four connecting slots are distributed in an annular array at equal distances and do not contact each other.

[0010] Preferably, the two first external connection holes are both located above the four connection slots and do not touch each other.

[0011] Preferably, the lower umbrella skirt is located above the two first external connection holes and does not contact them.

[0012] Preferably, the four connection blocks correspond to the positions of four connection slots respectively.

[0013] Preferably, the two second external connection holes are both located on the upper part of the four connection blocks and are not in contact with each other.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, a connection slot is provided at the lower part of the connection rod, and four connection slots are provided on the inner surface of the connection slot. At the same time, four connection blocks are fixedly connected to the outer surface of the connection pipe at the upper part of the device. When multiple devices are connected and used in combination, the connection pipe in the device can be inserted and connected with the connection slot at the lower part of the connection rod in another device, and the four connection blocks are respectively slidably engaged with the four connection slots, so that when multiple devices are connected and used in combination, not only do they not need to be fixed with bolts, but the multiple connected devices can also be more tightly engaged by the pulling force between each other when in use, so as to prevent the multiple connected devices from loosening when in use;

[0016] 2. In the utility model, by opening a group of external holes in both the connecting rod and the connecting tube, when multiple devices are connected and combined, the two groups of external holes will correspond to each other and be connected using latches, which can provide secondary fixation for the connection between the multiple devices. The two groups of external holes do not contact the four connecting slots and the four connecting blocks, and will not affect the fixed connection between the device and the external fixing parts.
