Abstract
The invention relates to the field of railway signal transmission, in particular to a gauge rod signal isolating device. The gauge rod signal isolating device is used for realizing electrical isolation on a gauge rod between two parallel steel rails so as to transmit signals on the two steel rails respectively without detaching the gauge rod or changing the gauge rod into an insulating gauge rod. The structure of the gauge rod signal isolating device consists of an annular ferrite core, a shell, and an inner sleeve, wherein the inner sleeve for sleeving the gauge rod is arranged inside the shell, and the ferrite core winds on the exterior of the inner sleeve and is fixed in the shell.
Description
Technical field
The present invention relates to the railway signal transmission field, especially a kind of gauge rod signal isolating device, be used for the tie rod between two parallel steel rails is realized electrical isolation,, and need not to remove tie rod or be replaced with insulated gage rod so that on two one steel rails, transmit signal respectively.
Background technology
Present rail and tie rod all are good conductors to direct current and AC signal, and railway track is made up of two one steel rails about parallel, the centre has tie rod to connect, because tie rod is a good conductor, the information that transmits on rail can be sent to another rail by tie rod.And need to remove or change tie rod, install and use inconvenience, be not easy to safeguard that existing equipment is an active equipment in addition, needs power supply.Therefore be subject to the influence of factors such as weather, geography, the ability that conforms is lower.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, compact, can install in a large number at the station, need not to dismantle original tie rod, easy to use, a kind of gauge rod signal isolating device of being convenient to safeguard is applicable to rail signal transmission in the railway territory.
Technical scheme of the present invention is: a kind of gauge rod signal isolating device 1, this apparatus structure is made up of ring-type FERRITE CORE 11, housing 12, inner sleeve 13, the inner sleeve of cartridge clip tie rod is located in the housing, and described FERRITE CORE is outside and be fixed in the housing around inner sleeve.
Described inner sleeve end is provided with the fixedly wire clamp 14 of tie rod of chuck.
FERRITE CORE chuck fixing clamper in the described housing is tightened to one with screw.
Described ring-type FERRITE CORE is that two symmetrical half round iron ferrite cores combine.
Described housing is a plastic material.
Beneficial effect of the present invention: apparatus of the present invention are mainly used in the transmission of railroad track signal.This device is installed on the nonisulated tie rod between rail, after apparatus of the present invention have been installed, induction reactance between two one steel rails has had the increase of geometric progression, make original two one steel rails become insulation by conductor by the electrical characteristic to set specific frequency signal between the tie rod, signal transmission between the two rails has been realized the electrical insulation between the two continuous one steel rails by ingenious " isolation ".Apparatus of the present invention utilize alternating electric field to produce alternating magnetic field, and alternating magnetic fields produces the theoretical foundation of alternating electric field, and the alternation of amplifying out obstruction magnetic field reaches the purpose that hinders the electric field alternation.Adopt apparatus of the present invention, do not need to remove or change tie rod, easy to install, cheap, avoid simultaneously safeguarding, be convenient to promote a large amount of installations.Apparatus of the present invention are inactive component, do not need power supply.Apparatus of the present invention are not subjected to the influence of factors such as weather, geography, also can use under complex environments such as morning and evening tides, dust storm, vibrations, high low temperature.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
The present invention is a kind of gauge rod signal isolating device, is applicable in the railway territory in the transmission of rail signal.As shown in Figure 1, apparatus of the present invention structural representation is made up of ring-type FERRITE CORE 11, housing 12, inner sleeve 13, and the inner sleeve of cartridge clip tie rod is located in the housing, and described FERRITE CORE is outside and be fixed in the plastic casing around inner sleeve.Described inner sleeve end is provided with the fixedly wire clamp of tie rod of chuck.FERRITE CORE chuck fixing clamper in the described plastic casing is tightened to one with screw.Described ring-type FERRITE CORE is that two symmetrical half round iron ferrite cores combine.
This device utilizes the action and reaction relation of electric field and magnetic field in the Theory of Electromagnetic Field, and classical electrical theory basis, realization becomes conductor the function of isolator under certain particular state, perhaps realize the signal of CF is the function that low resistance state is altered to high-impedance state, to reach the purpose that becomes electrical insulation by electric perforation.Its realization means are similar to the design of bandpass filter, but the difference of essence is arranged again on the principle.
Apparatus of the present invention signal is isolated operating principle such as Fig. 2:
This device is sleeved on the tie rod, and 3. tie rod 1. the time, can produce alternating magnetic field by alternating electric field around tie rod; Its magnetic line of force all passes magnet ring.2. the magnetic field of magnet ring produce an electric current opposite with the primary current direction again on tie rod.Promptly original electric current is produced the effect that weakens.
Quantizing this weakening degree then can be calculated by its induction reactance:
The induction reactance design formulas of this device is:
Induction reactance=jX1=2 ∏ fL.
2 ∏=6.28 are constant in the formula.
F is the frequency of alternating signal.
L is the inductance value of magnet ring.
Because of considering that the tie rod two ends connect rail, put circular magnet ring on tie rod can't construct, so circular magnet ring can be designed to two " Harvard " magnet rings, can be enclosed within on the tie rod easily.Fix two " Harvard " magnet rings with plastic casing and form a circular magnet ring.Be installed in schematic diagram on the tie rod as Fig. 3 for apparatus of the present invention.
Gauge rod signal isolating device of the present invention is simple in structure, compact, can install in a large number in the field, station, does not need to dismantle original tie rod, and engineering quantity significantly reduces, and to the not influence of original equipment.
Adopt apparatus of the present invention result after field trial as follows:
Send high-frequency carrier signal being on the rail of the left and right sides of distance tie rod 1K m, with the amplitude of oscillograph in tie rod two ends test carrier signal, the signal amplitude that records is for approaching 10/1000uV, illustrate that tie rod is to two rail short circuits, and the measuring-signal amplitude is 10mV after this device is installed, be 1000 times of signal isolation front signal intensity, this device of data comparative illustration has desirable signal isolation effect.
