Abstract
The utility model relates to a steel aluminium composite conductor rail device, which belongs to electric devices used by rail traffic. The steel aluminium composite conductive rail device mainly adopts the structure that the stainless steel slot of which the inner angle is 93 to 99 DEG is embedded in an I-shaped aluminum alloy sectional bar, so the stainless steel slot and the aluminum alloy sectional bar are integrated into a whole. A plug weld spot is arranged at the C point; a T-slot is arranged on the lower part of the I-shaped aluminum alloy sectional bar, and the abdominal region of the aluminum alloy sectional bar is provided with radiating fins. The structure of the utility model is compact and reasonable. Compared with the JV-52 low-carbon steel conductor rail, the utility model has small resistance, small pressure drop and good conductive performance. The number of power supply traction stations can be reduced, and the total investment of the power supply system can be reduced. The utility model has the advantages of good corrosion-proof performance, wear resistance, convenience, reliability, safety, and long service life.
Description
Technical field
The utility model relates to a kind of steel-aluminium composite conducting rail device, belongs to the electrical equipment that track traffic is used.
Background technology
Before the utility model is made, in prior art, subterranean railway, three rail electric power systems of track traffics such as ground light rail were originally used the I-shape rail transmission direct current (DC) of dead-soft steel, JV-52 dead-soft steel track as present Beijing Metro employing, its resistance is big, pressure drop is big, need be aided with copper cable heavy in section in addition along the line; The power supply Traction Station is short at interval, and investment is big.
Technology contents:
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compact conformation is provided, rationally; Resistance is little, and pressure drop is little, conducts electricity very well; Can reduce power supply Traction Station number, the electric power system gross investment reduces, the steel-aluminium composite conducting rail device of long service life.
Main solution of the present utility model is achieved in that
It is that 93 °-99 ° stainless steel tank 2 is embedded in the i section aluminium alloy section bar 1 that the utility model mainly adopts interior angle, makes it form one: the plug welding point is arranged at the C place; Be shaped on T slot 3 in i section aluminium alloy section bar 1 bottom; Be provided with radiating gill 4 at its belly.
Compared with the prior art the utility model has the following advantages:
1, compact conformation, rationally; 2, compare with JV-52 dead-soft steel conductor rail, resistance is little, and pressure drop is little, conducts electricity very well; JV-52 dead-soft steel conductor rail sectional area is 6543mm
2The time unit resistance be 19.0m Ω/Km; And sectional area is 6000mm
2The resistance of steel-aluminium composite conducting rail be 5.9m Ω/Km; Need the feed cable of the thousands of square millimeters in copper in parallel cross section in addition when adopting JV-52 dead-soft steel conductor rail along the line; Then can cancel 900mm at least behind employing the utility model
2Feedback copper cable or being provided with at interval of power supply Traction Station increase more than 1.4 times than JV-52 dead-soft steel conductor rail system, can reduce the Traction Station number of powering, electric power system gross investment reduction.3, anticorrosive property is good, wear-resisting, long service life, its unit weight only JV-52 dead-soft steel conductor rail 1/3rd, and installation and maintenance are convenient.4, owing to be shaped on T slot in i section aluminium alloy section bar 1 bottom and connect more reliably, the not perforate of belly of joint makes electric current not produce eddy current, reduces resistance and energy consumption; And each joint of JV-52 dead-soft steel conductor rail is made a call to 4 holes at belly at least, and electric current produces eddy current through this, and line resistance strengthens, energy consumption increases, because the i section aluminium alloy section bar has the setting of T slot, make the design of thermal expansion joint easier to be reliable, use safer.5, owing to be provided with radiating gill at i section aluminium alloy section bar belly, it obviously reduces the temperature rise K value that is caused by electric current when use or ambient temperature raise at full capacity, has improved and use working current of the present utility model in the upper limit of temperature rise K value.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly adopts i section aluminium alloy section bar 1,2 crimping of stainless steel tank to form, the stainless steel band roll extrusion flanging that stainless steel tank 2 employing thickness are 3-6mm forms, its interior angle is made 93 °-99 °, is embedded in the i section aluminium alloy section bar 1, makes it form one.Be aided with protective case, support, connecting cleat, thermal expansion joint, elbow and flow wire joint and form three rail transmission systems, i.e. steel-aluminium composite conducting rail device.Pantagraph current collector in the electric locomotive in moving is adjacent to the back moving contact with the stainless steel surfaces of steel-aluminium composite conducting rail under the effect of elastic force, thus with electric energy from powering the Traction Station on steel-aluminium composite conducting rail passes to electric locomotive travelling.Because stainless steel tank 2 is embedded in i section aluminium alloy section bar 1 top, under the compacted situation of stainless steel tank 2 bottom surfaces and i section aluminium alloy section bar 1 top upper surface to i section aluminium alloy section bar 1 top about two sides to the center F that presses, make the yield limit of the stress of aluminium alloy extrusions A, B position greater than its material, the distortion of aluminum alloy materials is sandwiched in the i section aluminium alloy section bar 1 two flangings of stainless steel tank 2, after side force F removed, stainless steel tank 2 still kept closed contact with aluminium alloy extrusions 1.Longitudinally punching has the plug welding point at position C place every a segment distance, carries out plug welding with argon arc welding and special welding rod, guarantees that further stainless steel tank 2 is more firm with combining of aluminium alloy extrusions 1.The utility model is shaped on T slot 3 in i section aluminium alloy section bar 1 bottom; And be provided with radiating gill 4 at i section aluminium alloy section bar 1 belly.
