Description
Technical field
The present invention relates to a kind of insulation detecting method, be specifically related to a kind of track plate insulation detecting method.
Background technology
Along with the development of society, the common target of pursuing in high-speed railway transportation having become countries in the world.For the requirement of the high stationarity that adapts to high-speed railway, high-durability, comfortableness, need to adopt and the ballastless track of the few maintenance of development.Because the transmission of Chinese Railway signal is carried out through rail; Rail is installed on the track plate; Track slab pavement on the line, track intralamellar part bar-mat reinforcement produces electromagnetic induction can produce bigger influence to the rail transmission signals, therefore; In order not influence rail signal is transmitted, the track plate must possess the good insulation performance performance.
Summary of the invention
The objective of the invention is to: a kind of method that detects the track plate insulation performance is provided.
Technical scheme of the present invention is: a kind of track plate insulation detecting method mainly contains following steps:
The first step, will be examined the track plate and placed on the smooth solid ground, two one steel rails will be placed on the support rail position of track plate;
Second goes on foot, with collets the rail pad is risen, and makes the flange of rail apart from support rail face 40-50mm, adjustment gauge to 1435 ± 5mm;
The 3rd goes on foot, connects with the end envelope of the zinc-plated twisted wire of being with chock plug with two one steel rails, and rail other end leading-out terminal is connected with measuring instrument;
The 4th the step, measure inductance value L and resistance value R between two rail leading-out terminals with alternating current bridge, test frequency is defined as f, measures at least three times, getting arithmetic mean is measurement result;
The 5th step, rail shifted out examined the track plate, and place on the insulating bodies, make the flange of rail apart from the height on ground with move rail before the flange of rail identical apart from the height on ground, adjustment gauge to 1435 ± 5mm, the end envelope company that keeps two one steel rails;
The 6th the step, measure inductance value L0 and resistance value R0 between two rail leading-out terminals with alternating current bridge again, test frequency is defined as f0, measures at least three times, getting arithmetic mean is measurement result;
The 7th step, calculating assay
The track plate is examined in calculating makes rail inductance relative deviation amount be (L-L0)/L0, and the track plate is examined in calculating makes rail AC resistance relative deviation amount be (R-R0)/R0; Satisfy (L-L0)/L0≤-3%, (R-R0)/the track plate of R0≤+ 10% condition is qualified.
Said f and f0 are respectively 2000Hz.
The invention has the beneficial effects as follows: whether the insulating property that detect the track plate meet the track circuit technical requirement.
