Description
Technical field
It the utility model is related to technical field of electrical measurement, more particularly to the contact line that a kind of aerial " П " type is rigid suspended
Wear away continuous measuring device.
Background technology
Nineteen eighty-three, " Π " type frame as one of overhead rigid suspension broad form is employed in Paris, FRA RATPA lines
Empty rigid suspension system." Π " type rigid suspension catenary system is with its simple in construction, convenient for installation and maintenance, safe and reliable, state
The characteristics of rate is high is produced, universal favorable comment is achieved in China's urban rail industry.From between 1997 in April, 2000, by middle ferroelectricity
Shanghai Underground engineering company of Group Co., Ltd of gasification office assembly, at the near coal-mine station of Guangzhou Underground No.1 line --- flower ground gulf station is carried out
After about 135 meters of " Π " type aluminium alloy bus-bar rigid suspension catenary test section, this installation form is formally introduced me
State, and used comprehensively in No. two line tunnel construction sections of Guangzhou Underground.At present, the country is existing and in the city rail traffic route built,
Significant proportion is accounted for using " Π " type bus-bar rigid contact net system, such as Guangzhou Underground No. two lines, No. three lines, ten
No.1 line, south-north line of Nanjing metro, No. nine lines of Shanghai rail transit, Hangzhou Subway, No. 6 lines of Beijing Metro and No. 14 lines etc. is all adopted
With this contact net system.
The rigid suspended elasticity the same due to not possessing flexible suspension, bow net contact fluctuation is more violent, pantograph contact line relation
More deteriorate, plus metro traction electric current is big, the section method of operation is fixed, in section, specific portion section arcing is serious, finally
Cause all fronts abrasion of contact wire extremely uneven, section particular section abrasion of contact wire is apparently higher than other sections.To ensure rigidity
Contact net health operation, run unit periodically will measure statistics to all fronts abrasion of contact wire situation, find to wear with timely
Serious section work specified point, and maintenance project is formulated in advance.
Traditional contact line Abrasion detecting equipment is broadly divided into two classes：Vehicle-mounted detection apparatus and Handheld detection device.Car
The typical technical solution of load detection means has the side using German DB companies as " the more mesh line-scan digital camera+triangle Cleaning Principles " of representative
Case, as shown in Figure 1.The program is limited by the resolution ratio and image recognition algorithm of line-scan digital camera, and dynamic carrier equally docks
The measurement for touching line abrasion adds higher difficulty.
Fig. 2 is the simple measuring principle figures of Italian MERMEC, and laser beam with 45 ° of contact line bottom angle to beat in contact line
On, it is then able to be formed one on contact line bottom surface curve, CCD camera can capture this curve and carry out coordinate transform,
So as to accurately be measured contact line abrasion, other contact net geometric parameters can be also measured simultaneously certainly.
Hand-held contact line Abrasion detecting device is then more simple compared to vehicle-mounted detection apparatus, is mainly grouped as two at present
Class：Slide measure and residual high abrasion measuring instrument.Comparatively, slide measure is more original, and measurer simply is applied into abrasion surveys
Amount, but the top half of rigid suspension OCS rigidity busbar contact line has been embedded in bus-bar, therefore use slide measure
The remaining residual height of contact line can not be measured, contact link friction bottom width can only be measured, operating error is larger, can not ensure measurement essence
Degree.Residual high abrasion measuring instrument uses contact type measurement mode, and dress is realized first with the triangle chamfer profile of bus-bar lower surface
The positioning with bus-bar and contact line is put, is extruded afterwards using device central contact and contact wire, the contact when wearing away larger
Retraction stroke is smaller, and it is larger that abrasion retraction stroke occur when smaller, therefore it is remaining high according to contact travel change to calculate contact line
Degree, it is simple in construction.More uncertain factor be present in the metering system：First, it is bonded with the positioning of bus-bar and only leans on manpower, surely
Qualitative difference；Secondly, binding face easily assembles that conductive paste, dust be dirty and ablation pit, influences measurement accuracy；Finally, position
Easily there is deflection measurement, influences measurement accuracy without locking mechanism in mode.Deficiency is outer more than, and existing hand-held rubs difficult to understand measure
The shortcomings that device is bigger is that measurement is only capable of realizing spot measurement, can not realize continuous measurement, and attendant can not be from the palm directly perceived
Hold abrasion of contact wire situation.
