The advantage the utlity model has and effect:
1, the utility model adopts double insulation, and when the first heavy insulation breakdown, second heavily insulate and can normally use, and when the second heavy insulation breakdown, first heavily insulate can play insulating effect, has improved security of system coefficient.
2, the utility model adopts double insulation, not only can improve integral insulation ability and the lightning impulse tolerance of contact system, but also can make contact system reduce aerial earth wire, its aerial earth wire saving can be applied in strong thunder area, directly as lightning conductor.Save material, further improved the safety of contact net system.
3, tramway train and public transit system are shared right of way, and pedestrian shuttles back and forth under tramway train contact net for power supplying, and the utility model adopts double insulation structure, the safety that has greatly improved contact system, and the tramway train that is applicable to very much running in bustling city is used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is that the A of Fig. 1 is to enlarged drawing.
The specific embodiment
1,2 the first embodiment of the present utility model is described by reference to the accompanying drawings.
A tramway train contact net for power supplying cantilever positioning device, is characterized in that: described device consists of cantilever base 1, bracket insulator 2, horizontal bracket 3, lateral conductor 4, bracing wire base 5, positioning support 6, steady arm 7, steady ear 8, steady ring 9, hoist cable bearing 10 and guy insulator 11; The inner of described horizontal bracket 3 is connected with one end of bracket insulator 2, and the other end of bracket insulator 2 is connected with cantilever base 1, and cantilever base 1 is fixed on the top of column 12; The middle part of described horizontal bracket 3 is fixed with positioning support 6 and hoist cable bearing 10, and outer end is fixed with steady ring 9, and makes hoist cable bearing 10 between positioning support 6 and steady ring 9; On described positioning support 6, insulation locator 7 is installed, the outer end of insulation locator 7 is provided with steady ear 8; The upper end of described lateral conductor 4 is connected with one end of guy insulator 11, and the other end of guy insulator 11 is connected with bracing wire base 5, and bracing wire base 5 is fixed on the top of column 12; The lower end of described lateral conductor 4 is connected with steady ring 9; Described hoist cable bearing 10 is positioned at the top of steady ear 8, and insulating hanging bands 13 middle parts are fixed on hoist cable bearing 10, and two ends are all connected with suspending cable clamp 14.
The location organ pipe of described insulation locator 7 is metal tube, and is crimped with insulator 15 in the middle of the organ pipe of location.Described insulating hanging bands 13 is metal wool, and the two ends of hoist cable line are crimped with respectively strut insulator 16, and makes strut insulator 16 between suspending cable clamp 14 and hoist cable bearing 10.
