Description
Technical Field
The utility model belongs to electronic railway removes contact net field, concretely relates to remove contact net contact wire and set up the structure.
Background
The contact wire in the existing mobile contact net is directly arranged on the cantilever, one mode is that the contact wire and the catenary are separately arranged on the cantilever, the other mode is that the catenary is arranged at the upper end and the contact wire is arranged at the lower end through a shared rotary supporting shaft, but no matter what type is adopted, the contact wire is directly or indirectly arranged on the cantilever and is fixed. A positioning wire clamp is needed to clamp a contact wire, and sometimes the positioning wire clamp (a contact wire clamping structure) is provided with a slide way and other structures.
The contact net hard point is that when the elasticity of some parts on the contact suspension or contact line is poor or additional weight is added at the positioning points at two ends of the span, when the locomotive pantograph runs through at high speed in the running of the electric locomotive, the parts are abnormally raised (or lowered), even the phenomena of pantograph collision and pantograph collision occur, and the intrinsic state forming the phenomena is the hard point. The hard spot of the contact net is a threatening physical phenomenon, which can destroy the normal contact and current collection between bow nets, accelerate the abnormal abrasion and impact damage of the lead and the pantograph slide plate, often cause sparks or arc discharge at the parts, and further damage contact wires and the pantograph. The occurrence of contact line hard spots can also influence the normal current taking of the traction motor, cause serious damage to the traction motor in the transient process of arc discharge, and simultaneously influence the traction quality of the locomotive.
There are two kinds of damage to the contact net and pantograph by the hard spot, one is mechanical damage, and the other is arc damage. The mechanical damage refers to slight impact, scratch and the like to the pantograph and the contact wire (obvious trace is called as a pantograph point), generally speaking, the damage of a hard point to the pantograph (net) is mainly caused by the high-temperature electric arc generated instantly when the pantograph net is off-line and off-line due to the hard point, and the high-temperature electric arc has great harm to the contact net and the pantograph. The main damage to the pantograph is pitting and vaporization of the pantograph head. The damage to the contact wire is high temperature annealing of the wire, in addition to pitting and vaporization of the contact wire.
The hard contact point is one of the important reasons for the offline of the locomotive pantograph, and the offline of the locomotive pantograph has harm to a locomotive traction motor, an electric appliance, the pantograph, a contact network, a traction transformer and a power supply system.
The contact net hard spot causes mainly are:
1. the design reason is as follows: because the special-shaped positioners are adopted at the joints of the insulated anchor section and the split-phase insulated radium section, the positioners are heavier and centralized, and the elasticity of the positioning part is reduced; the electric connection of the isolation switch, the lightning arrester and the internet is heavier and concentrated at the part of the element type split-phase and segmented joint and the electric connection wire clamp, so that the contact force of the pantograph is suddenly changed to cause a larger impact hard point.
2. The material reason is as follows: the alloy contact wire has uneven crystal grains, stress exists in the wire, wave bending is formed under the action of tension, and hard points are formed in the contact wire in the manufacturing or coiling process.
3. The construction reason is as follows: the contact wire is not paid off by constant tension in the paying off process and is not paid off according to the construction process to form a hard point; in the installation and adjustment of the contact net, a worker steps on the contact wire and the operation vehicle lifting platform directly lifts the contact wire to generate a hard point.
4. The reason of power supply is as follows: the contact net positioning wire clamp, the dropper wire clamp, the electric connecting wire clamp, the connector wire clamp and the central anchor wire clamp are deflected; at the position with larger (smaller) positioning gradient, the nail stopping gap of the positioner is not standard, and the elasticity is poor (the positioner cannot be raised normally); the slope change of local wires is large (the slope of the contact wires is large due to severe height change of the contact wires at positions of a bridge, a tunnel portal and the like), the height difference between positioning points and between dropper points exceeds the standard, the dropper is not uniformly stressed or one dropper is greatly stressed, and a hard point is formed.
