Description

Technical Field

[0001] The invention belongs to the technical field of electrified railway and urban rail transit power supply contact network, and in particular relates to a segmented insulator tension detection installation platform. Background Art

[0002] The segmented insulator is an important component in the power supply contact network system of electrified railways and urban rail transit. Its function is to make the contact network electrically segmented without affecting the normal passage and current collection of the pantograph. The segmented insulator can be divided into two types according to the slide type: slide type and non-slide type. The non-slide segmented insulator is widely used because of its good insulation performance and arc extinguishing ability. However, the non-slide segmented insulator has high technical standards for spatial geometric parameters, and there are problems such as cumbersome on-site installation and debugging steps and low efficiency. In order to simplify the installation steps and improve the efficiency of on-site construction, the non-slide segmented insulator is generally pre-installed before leaving the factory, that is, its main part and metal slide and other components are installed and debugged in place before leaving the factory, and no secondary adjustment is required during on-site installation. However, the existing installation and debugging are all carried out under the condition that the segmented insulator is not subjected to working tension. When the segmented insulator is subjected to working tension, the overall structure will deform along the force direction, resulting in poor contact with the pantograph, and the smooth passage of the pantograph cannot be guaranteed, which directly affects the normal use of the non-slide segmented insulator.
