Description
Technical Field
The utility model belongs to the technical field of electronic track traffic, a transmission line that erects to the power supply of electric locomotive along the track traffic route is the contact net, especially relates to the insulating linkage of contact net.
Background
The overhead contact system is a transmission line which is erected above a track traffic line and supplies power to an electric locomotive, is an important task of directly transmitting electric energy obtained from traction power transformation to the electric locomotive for use, and is outdoor power supply equipment without standby. Therefore, the quality and the working state of the urban rail transit contact network directly influence the operation safety of rail transit. In recent years, with the increase of lightning disasters, the lightning accident rate of the contact net is in an increasing trend, so that the insulation of the contact net is enhanced, and the improvement of the lightning overvoltage resistance of the contact net plays an important role in the operation safety of urban rail transit and even national economy.
An original suspension supporting device is shown in fig. 1 and comprises a support column or a wall or other supports (not shown in the figure), a horizontal cantilever 04 and an inclined cantilever 07 are connected to the support column through a metal base 01 and an insulator 02, the outer ends of the two cantilevers are connected with each other, a cantilever supporting rod 03 is further arranged between the two cantilevers, a force-bearing wire clamp is arranged at the end of the horizontal cantilever 04 and used for fixing a main wire in a contact net, one end of a positioning tube 08 used for suspending a contact net wire is connected to the inclined cantilever 07, the other end of the positioning tube 08 is connected with the horizontal cantilever 04 through a diagonal wire 06 and a connecting piece 05, and a positioner 09 is connected to the positioning tube and used for connecting a lead in the contact net. Except that the insulator 02 is made of insulating materials, the main components in the structure are made of conductive steel, and the electrical performance of the whole set of device depends on the characteristics of the insulator. The insulators commonly used in the prior art mainly adopt three types, namely ceramic insulators, toughened glass insulators and composite insulators (silicon rubber). Although the three insulators are made of different materials, the three insulators have the advantages that the insulation performance of the insulators is guaranteed by the shape creepage distance generated by the concave-convex of the insulators, and the three insulators have the common defects:
(1) the surface of the structural model of the insulator is uneven to generate natural dirt accumulation and is not easy to clean, and under severe meteorological conditions of heavy fog, light rain, dew, snow melt, ice melt and the like, the surface of the insulator is easy to form a continuous water film, and the conductance of a dirt layer is high, so that the leakage current is also very large, strong local electric arcs are easy to generate, and the further development of the local electric arcs causes external insulation flashover. The problem of insulator pollution flashover is always the main problem of external insulation, and the pollution flashover seriously threatens the safe operation of a contact net.
(2) When the lightning strike happens, due to the limitation of the voltage level of the contact network, the insulator of the contact network is very easy to break down, so that the internal insulation is damaged, and particularly when the insulator is influenced by strong pulses caused by the lightning strike around, the local temperature on the surface of the insulator is suddenly increased, so that the insulator is damaged, and the zero-value effect of the insulator is caused. The harm brought by the method is that the transportation line powered by a contact net stops running, and the social influence is huge.
(3) The support post, the inclined cantilever, the horizontal cantilever and the carrier cable supporting wire clamp in the suspension supporting device are all made of metal materials, and the corrosion and the aesthetic problems of the metal materials are obstacles which disturb the technical development of the contact network.
(4) The existing insulators are mostly porcelain insulators, and under the action of a direct-current electric field, the electromechanical properties of the insulators are reduced due to aging of the porcelain insulators caused by ion migration, so that accidents are easily caused.
Today, the development of rail transit is increased in China, and the improvement on the structure of the existing contact net suspension device is urgent. We summarize the past teaching and training, find that to improve the overhead contact system and hang the electrical property, fully guarantee the overhead contact system safety, must begin from structural style and material two aspects and carry out thorough transformation.
