Description
Technical field
The present invention relates to a kind of tuned cell circuit, a kind of tuned cell circuit for improving stability is specifically referred to.
Background technology
At present, ZPW-2000A non-insulation move frequentlies track circuit, the quilt in the railway signal system of both wired and Line for Passenger Transportation
Extensive utilization.Its Key Circuit is electrical insulation section circuit, plays the electrical isolation of track circuit between adjacent sections.Electric insulation
The rail inductance in economize on electricity route tuned cell circuit, air core coil and tuning area is collectively constituted.Wherein, tuned cell circuit then by
Inductance and capacity cell are constituted, according to the frequency characteristic of its track circuit, be divided into 1700Hz, 2000Hz, 2300Hz, 2600Hz this
4 kinds of different model specifications.
Described tuned cell circuit has two kinds of structure types, separately constitutes tuned cell (BA) and resonance matching unit
(PT) two kinds of equipment, for both wired and passenger dedicated railway line signal system.In order to improve the stability of tuned cell circuit, need
The tuning circuit polyurethane material that inductance and capacity cell are constituted is packaged in special box body, improve its anti-vibration and
Shock resistance, so as to ensure the stability and reliability of tuning circuit.
Tuned cell (BA) and resonance matching unit (PT) both equipment are installed on by track, and condition of work is severe, are needed
Bear the temperature of extremely trembling with fear in -40 DEG C of winter, it is also desirable to bear 70 DEG C of high temperature of summer, in freezing winter and in sultry summer, the change for going round and beginning again.Adjust
Humorous element circuit has to steady operation, and its impedance value must be controlled in the range of the technical indicator of regulation, could cause tuning
The whole circuit in area can just be operated in reliable and stable state, it is final ensure electrical insulation section adjacent orbit section it is good it is electric every
From degree.

In the parallelogram that resistance is constituted, according to 4 kinds of different frequency characteristics, the impedance targets of tuned cell circuit respectively as Fig. 1,
Shown in Fig. 2, Fig. 3, Fig. 4, wherein unit is m Ω.

Real part resistance can change with the change of temperature, and real part resistance value can even more exceed the index frame model of parallelogram when serious
Enclose, so as to cause tuning destroyed, cause the electrical isolation degree of electrical insulation section to decline.So, in the life of tuned cell circuit
Produce in debugging process, the requirement to production environment is high, it must be put tested equipment under 25 DEG C of regulation of environment temperature
After putting 24 hours, debugged and detected under identical environment temperature, it is necessary to by real part resistance and the adjustment of imaginary part resistance flat
The centre position of row quadrangle index frame.Only in this way, under extreme high and low temperature state, its impedance targets could meet just
Normal use requirement.
In the prior art, due to inductance, electric capacity, etc. the resistance element such as line be respectively provided with certain temperature coefficient, add encapsulation etc.
The influence of factor, using scene, the resistance of usual real part resistance can exceed indication range, it is impossible to meet use requirement, while
Cause the yield rate of product low.Its reason is analyzed, major factor is the multiply copper core polychlorostyrene second for waiting resistance line using RV48 × 0.2
Alkene insulated wire, is 0.0039 because the temperature-coefficient of electrical resistance of copper conductor is larger, and temperature is raised, and the corresponding resistance for waiting resistance line is therewith
Increase.If it is resistance line to use relatively low material work of temperature coefficient etc., the temperature stability of real part resistance can be just greatly improved, improved
The qualification rate of product, improves the stability and reliability of frequency shift modulated track circuit electrical insulation section.
