Abstract
The utility model discloses a rail current sensor, which belongs to the technical field of the sensor and comprises a measuring coil and a fixture which is fixedly connected with the measuring coil and clamped on the lower edge of the steel rail. The rail current sensor when in used is clamped under the steel rail by the fixture, therefore the coil couples with the current passing through the steel rail. The rail current sensor solves the problem that, at present in the field of the traction power supply for the electric rail, in the steel rail the traction current is measured according to the mechanical insulation joint and the signal current is measured according to the mechanical insulation joint and the electric insulation joint, therefore any of the traction current and the signal current cannot be measured on the ground as required, is solved.
Description
Technical field
The utility model relates to a kind of sensor, relates in particular to a kind of track current sensor that is used for measuring track current.
Background technology
In the electric railway traction field, traction current in the rail and marking current are the important evidence that daily state detects and troubleshooting is analyzed of rail, at present, measure two chokes of electric railway track drawing backflow general using mechanical insulated joint and become centre tapped line, electric current loop is enclosed within on this line measures.Train operation do not having on the interval circuit of mechanical insulated joint, owing to can not be overlapped electric current loop, thereby can't be carried out the measurement of rail current on rail; Two rail extension lines of the measurement general using mechanical insulated joint of marking current and electronic isolation joint are measured.On rail in the middle of the block section that does not have mechanical insulated joint and electronic isolation joint,, also can't carry out the measurement of marking current because train operation is same owing to can not overlap electric current loop on rail.
The utility model content
The purpose of this utility model is to provide a kind of can be convenient for measuring the traction current of optional position in the rail and the track current sensor of marking current on the ground.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Track current sensor of the present utility model comprises and measures coil and the jig that can be connected on the rail lower edge that described measurement coil and described jig are fixed together.
Described jig is " U " type jig, and described measurement coil is around the bottom of " U " type jig, and there is the groove that can be stuck in both sides, rail lower edge at the two ends of described " U " type jig.
The beneficial effects of the utility model are as follows:
Track current sensor of the present utility model can be measured traction current in the optional position of the rail that comprises the interval circuit that does not have mechanical insulated joint, thereby can draw the current division ratio example of traction current net at any part of path, and then judge whether the backflow ratio is normal, be convenient to pinpoint the problems, rectification in time guarantees safe train operation; Simultaneously, track current sensor of the present utility model can be at the optional position measuring-signal electric current of the rail that comprises the block section that does not have mechanical insulated joint and electronic isolation joint, can draw the marking current amplitude and with the band interference current amplitude, and then judge that track circuit is subjected to annoyance level, be convenient to state-detection and troubleshooting and maintenance.The analysis that the detection data can be the track circuit parameter simultaneously facilitates.
Description of drawings
Fig. 1 is the structural representation of an embodiment of track current sensor of the present utility model;
Fig. 2 is the synoptic diagram of the embodiment of the track current sensor shown in Fig. 1 at rail traction current and current measuring signal;
Fig. 3 is the measuring principle synoptic diagram of track current sensor of the present utility model.
Embodiment
Track current sensor of the present utility model adopts the electric current that flows through in the mutual inductor coupling rail according to electromagnetic induction principle, and its induced voltage causes the sampling and measuring instrument by terminal, carries out sampling and measuring.
Referring to accompanying drawing 1, an embodiment for track current sensor of the present utility model comprises coil 1 and jig 2,2 one-tenth " U " types of jig, and coil 1 is around the bottom of jig 2.This enforcement utilization is used for measuring the mode of traction current and marking current and sees Fig. 2 on rail, jig 2 is stuck in the both sides of rail 3 lower edges, and the two ends of the lower edge of rail 3 are stuck in the groove at jig 2 two ends.The concrete principle of measuring is seen Fig. 3, when rail current 5 is flowed through in the rail, the magnetic line of force 4 that produces passes coil 1, thereby produces induction electromotive force in coil 1, and the induction current in the described coil 1 is received on the external unit by connection terminal 6, external unit can be oscillograph, oscillograph, spectrum analyzer, be used for carrying out the Real Time Observation analysis, also can be recorded in data recorder, non-volatile recording, in lab analysis, draw the large sample statistic analysis result then.
In order to adapt to on-the-spot the use, the track current sensor that this practicality is new should shockproof, moistureproof, high-low temperature resistant.
Claims (2)
1. the track current sensor comprises the measurement coil, it is characterized in that: also comprise the jig that can be connected on the rail lower edge, described measurement coil and described jig are fixed together.
2. track current sensor according to claim 1, it is characterized in that: described jig is " U " type jig, described measurement coil is around the bottom of " U " type jig, and there is the groove that can be stuck in both sides, rail lower edge at the two ends of described " U " type jig.
