Embodiment 1
[0049] Such as figure 2 As shown, the slideway-type rhombic segmental insulator has a structure including joint clamp 2, bridge insulator 5, metal slideway 4 and insulating slideway 3, wherein the metal slideway 4 and the insulating slideway 3 are two and connected to each other. Intervals form a rhombus structure, and the longitudinal two ends of the rhombus structure are respectively connected to the connector clamp 2, which is an important part of the contact sliding surface 7 that is in contact with the locomotive pantograph and allows it to slide over. The section insulator is connected with the contact wire on the driving line, and assumes the role of electrical section on the electrified railway, urban light rail and subway contact network.
[0050] The transverse ends of the rhombus structure are respectively connected to the bridge insulators 5, and the insulating slide 3 adopts the insulating rod of the catenary segmenter, and the structure of the insulating rod of ...
Embodiment 2
[0054] Such as figure 1 As shown, on the basis of Embodiment 1, the ceramic composite material part 1 in this embodiment is a plurality of sequentially connected cylindrical structural components.
[0055] This structure further increases the bearing pressure of the insulating rod of the catenary sectionalizer, improves the elasticity of the catenary, effectively improves the use effect of the product, and greatly prolongs the service life of the product.
Embodiment 3
[0057] On the basis of Example 2, the outer structure of the composite insulating rod described in this example: the inside is a mandrel made of chemical fiber bundles, and the outer surface is an insulating protective layer.
[0058] Among them, the inner core rod can be made of epoxy glass fiber reinforced plastic core rod, which has a large allowable stress, can meet the use requirements in terms of bearing contact line tension, bending deflection, etc., and has a large safety margin. The insulating protective layer is made of silicone rubber umbrella cover, which is resistant to pollution flashover voltage and is not easy to be damaged.

Abstract
The invention discloses a sliding track type diamond section insulator. The sliding track type diamond section insulator structurally comprises connector wire clamps, a bridge insulator, two metal sliding tracks and two insulating sliding tracks. The two metal sliding tracks and the two insulating sliding tracks are mutually spaced to form a diamond structure, the two longitudinal ends of the diamond structure are connected with the connector wire clamps respectively, the sliding track type diamond section insulator is connected with a contact wire on a running line through the connector wire clamps, and the two transverse ends of the diamond structure are connected with the bridge insulator. Overhead contact line sectionalizer insulating rods are adopted for the insulating sliding rails and structurally comprise inside composite insulating rods and outside ceramic composite material pieces, and the composite insulating rods are sleeved with the ceramic composite material pieces. The composite insulating rods are good in tension bearing capacity and are sleeved with the multiple stages of composite material pieces in series connection, so that arc resistance is achieved, damage is not likely to occur, the service cycle is long, and the problems that in the prior art, insulating sliding tracks are not resistant to wear, likely to be carbonized, not resistant to arcs and short in service life and need to be regularly replaced are solved.
Description
technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a slideway-type diamond-shaped section insulator used in contact suspension of electrified railways, urban light rails and subways. Background technique [0002] Sectional insulators are used in the loading and unloading lines, locomotive maintenance lines and electric locomotive garage lines of various stations in the electrified railway section. In order to ensure the convenience and personal safety of the staff, the catenary is divided into independent sections in terms of electricity. . [0003] Sectional insulators are installed at both ends of the above-mentioned independent section, and its structure can not only ensure the sectioning of power supply, but also enable the pantograph to pass through the equipment smoothly. [0004] At present, there are a variety of segmented insulators with different structures at home and abroad. The following typ...
