Embodiment 2

[0055] The technical features of the segmented insulator 100 in this embodiment are basically the same as those of a segmented insulator 100 in the embodiment, the difference is that in this embodiment, please refer to Figure 7 , along the depth direction of the first groove 12, the width of the second groove segment 122 along the sliding direction of the power receiving shoe 300 first gradually increases, and then gradually decreases. Moreover, the first cross section of the second groove segment 122 is connected by an arc segment, specifically an ellipse.

Embodiment 3

[0057] The technical features of the segmented insulator 100 in this embodiment are basically the same as those of a segmented insulator 100 in the embodiment, the difference is that in this embodiment, please refer to Figure 8 , along the depth direction of the first groove 12 , the width of the second groove segment 122 gradually increases along the sliding direction of the power receiving shoe 300 . In addition, the first section of the second slot section 122 is connected by an arc section and a straight section, which is T-shaped specifically, and the top end is provided with rounded corners of the arc section.

Abstract

The invention relates to the technical field of rail transit contact rail systems, and provides a sectional insulator which is provided with a first working surface for a power receiving shoe to slide, a plurality of first grooves are formed in the first working surface, and the first grooves are distributed at intervals in the sliding direction of the power receiving shoe; the first groove comprises a first groove section and a second groove section which are sequentially distributed in the depth direction of the first groove, and a step used for preventing conductive dust from escaping fromthe second groove section to the first groove section is formed between the second groove section and the first groove section. The invention further provides a contact rail system. The contact rail system comprises the section insulator and a contact rail section. According to the section insulator provided by the invention, the phenomenon of power channeling between adjacent power supply sections can be avoided, and thus the safety of personnel in the operation and maintenance process is ensured.

Description

technical field [0001] The application belongs to the technical field of rail transit contact rail systems, and more specifically relates to a segmented insulator and contact rail system. Background technique [0002] In the field of rail transit, some standard lines use the contact rail segment to supply power to the vehicle, and the segment insulator is an insulation device used when the contact rail is segmented for electrical segmentation. Under normal circumstances, the electrified shoe slides through. When a fault occurs in a certain contact rail section or the power is cut off due to construction, the isolation switch at the section insulator is turned on to cut off the power supply of the part of the catenary, while other parts can work normally and supply power. [0003] However, during long-term use, the conductive particles generated by the friction of the electric shoes will adhere to the inner wall of the channel, affecting the electrical insulation performance ...
