The insulator is installed correctly, the surface of the insulator glaze is smooth and clean, the defects of cracks, glaze shortage, spots, bubbles and the like are avoided, and the insulator glaze is peeled off from the total surfaceProduct is not more than 30mm2. The fastener is complete, and the installation is firm reliable.
Description
Technical Field
The utility model belongs to the technical field of hang the contact net in the tunnel, concretely relates to anchor assembly fixed knot constructs under contact wire.
Background
The overhead line system is an important component of an urban rail transit power supply system, is a special form power transmission line which is arranged along a rail transit line and supplies power to an electric locomotive, is a special power supply device for supplying power to the electric locomotive or an electric locomotive group for rail transit and has no standby power supply equipment. The contact net can always keep normal and stable contact current collection in the high-speed running of the locomotive, has enough wear resistance and good conductivity, has the service life as long as possible, strives for simple structure, and stable performance is easy to construct and maintain.
And a rigid-flexible transition system is arranged at the tunnel portal where the flexible suspension and the rigid suspension are connected. The pantograph suspension device is a key part for realizing seamless connection between the rigid suspension and the flexible suspension, and ensures stable transition of the pantograph between the two suspensions. The main components comprise a chemical anchor bolt, a wrist support device, a positioning device, a contact line, an overhead ground wire, a rigid-flexible transition element and the like.
At the lower anchor position of the contact line, the edge distance of the insulator from the pantograph envelope line is not less than 75 mm; the distance between the rigid suspension live body and the flexible suspension lower anchor base, the lower anchor support suspension and other grounding bodies is not less than 150 mm. The distance between the pantograph and the grounding bodies such as the flexible suspension lower anchor support base and the lower anchor support suspension is not less than 150 mm.
