Abstract
The utility model discloses a rhombus power supply section insulator, comprising two insulating elements and two conducting bodies. The insulating elements and the two conducting bodies are in the interphase connection to form into the rhombus power supply section insulator. The longitudinal isolation is changed into the lateral isolation, and the length of the insulator is shortened. The utility model has the advantages of light weight, simple structure, simple manufacture, convenient maintenance, and low cost. In virtue of the isolation on the single side, the pantograph of the electric locomotive has the short circuit instant on both sides; the electric locomotive does not generate the spark when the electric locomotive passes through the insulator. By adopting an arc guiding rod, the electrical arc generated does not damage the insulating element even if the condition of the short circuit to the earth occurs. The utility model is good for the promotion of the power supply contact system.
Description
The utility model belongs to the improvement of contact nets in electrified railways sectioning.
What China's contact nets in electrified railways segmentation was adopted at present is the C-1200 section insulator of railway research institute's development, its water conservancy diversion framework by irony, horizontal palm frame, angle bar frame, stull pipe etc. constitute, reach 3350 millimeters, wide 270 millimeters, 16.5 kilograms of weight.This has caused the contact system poor flexibility, brings difficulty for the raising train running speed.Electric locomotive can produce spark during by this shackle inevitably.When if shorted to earth takes place, the electric arc of the generation damage insulation component that can burn.
Thereby purpose of the present invention is exactly to be the length that the lateral isolation structure shortens shackle with the vertical insulation improvement of electric section insulator circuit, alleviates the weight of shackle, increases the elasticity of contact system, provides condition for improving train travel speed.Produce the spark or the insulation component of burning when avoiding electric locomotive by shackle.
Characteristics of the present invention are that shackle thoroughly does away with the edge element by two and two flow deflectors constitute diamond structure, the alternate connection with flow deflector of the insulation component on rhombus four limits.Two diagonal angles of the vertical rhombus of circuit connect with contact system two section leads respectively, and two horizontal diagonal angles are connected firmly by an insulating part.The part that flow deflector stretches out the rhombus outside constitutes arc guide rod.
The utility model has adopted diamond structure, and becoming vertically insulate is lateral isolation, and the length of shackle shortens greatly, weight alleviates greatly, the elasticity of contact system is improved greatly like this, has created condition for improving train travel speed, for country has saved insulating material and steel.Shackle is the monolateral insulation of rhombus, when electric locomotive is traveling in lead segmentation intersection point place, because pantograph pan touches two flow deflectors simultaneously, produce short circuit, when having avoided electric locomotive like this by the C--1200 section insulator must produce the sort of phenomenon of spark.Particularly adopted arc guide rod, on shackle one side joint ground, under the charged improper situation of a side, when block of bow collector of electric locomotive during by lead segmentation intersection point place, arc guide rod has guaranteed that spark can not damage insulation component.The present invention, simple in structure, be easy to make, cost is low, is beneficial to apply.
Description of drawings:
Fig. 1 is the birds-eye view of rhombus electricity section insulator.Shackle thoroughly does away with edge element (1) and (1 ') and two flow deflectors (2) and (2 ') by two and constitutes rhombus.The vertical rhombus of circuit two diagonal angles respectively and lead (5) and (5 ') are fixed in (6) and (6 ') are located, laterally rhombus two diagonal angles connect firmly with insulation component (3).It is arc guide rod (4) and (4 ') that flow deflector (2) and (2 ') prolong in the rhombus Outboard Sections.
Figure two is that rhombus electricity section insulator hangs on the installing figure on the contact system circuit.Shackle (10) is hung on the contact system catenary (7) by 4 droppers (9), and catenary central authorities connect an insulating part (8).
Specific embodiment:
When the pantograph of operating electric locomotive is located to move on insulation component (1) and the flow deflector (2) through connecting (6) by lead (5), insulation component (1) and flow deflector (2) are held up by pantograph simultaneously, rhombus electricity section insulator is steady, and electric locomotive is flowed from flow deflector (2).When operating block of bow collector of electric locomotive moved to insulation rod (3) position, flow deflector (2) contacted the pantograph pan short circuit simultaneously with (2 '), and no spark produces.Thereafter, block of bow collector of electric locomotive is subjected to stream by electric section insulator from flow deflector (2 '), another section lead (5 ') that carries out the transition to contact line conducting wire is because the rhombus shackle is symmetrical, and it is the same that electric locomotive carries out the transition to another section lead (5) effect by lead (5 ').
Claims (1)
- A kind of contact nets in electrified railways section insulator of making by insulation component and electric conductor, it is characterized in that the alternate diamond structure that is connected into of insulation component and flow deflector, vertical two diagonal angles of this structure are affixed with contact line conducting wire respectively, horizontal two diagonal angles of this structure are connected firmly by insulating part, and flow deflector extends the rhombus outside and constituted arc guide rod.
