Part.
Electric locomotive（Including metro traction locomotive）Angle induction element species in driver controller is more, as line around
Middle Eocene device, angular encoder etc..It is then thing in recent years that conductive plastics angular transducer is used for controller with its excellent performance
Feelings.The core component of this kind of sensor is conductive plastic resistance body, spraying is usually used, made of heat pressing process.Conduction modeling
The operation principle for expecting angular transducer is that the control handle of controller is connected with the shaft of sensor, moves the rotational angle of handle
Change substantially with resistance value has functional relation, according to the voltage divider principle of resistor, it is possible to realizes that rotation angle size turns
Become the voltage signal of height, for the speed for controlling the direction of motor sport and advancing.The confession of angular transducer in controller
Power supply is from power circuit along the line, since locomotive is starting and running the load change of period, locomotive across operation by sections
When power section power supply difference and power supply department to power circuit load allotment etc. factor, more or less cause to sense
The fluctuation of device operating voltage, it exports signal and also fluctuates therewith, its consequence is to cause locomotive speed unstable, when controller controls
When handle is removed to designated position, predetermined speed is not reached, locomotive is in micro- runaway condition, causes a hidden trouble to locomotive operation.
The content of the invention
In order to solve technical problem present in above-mentioned background technology, the present invention provides a kind of conductive plastics voltage than defeated
Go out angular transducer, which abandons the traditional voltage output side of potentiometric transducer than output angle sensor
Formula, is exported by voltage than in a manner of, which is certain value, will not be influenced by working sensor voltage fluctuation, and causes machine
Car speed wobble.
The technical proposal of the invention is realized in this way：
A kind of conductive plastics voltage is arranged on resistive element than output angle sensor, including resistive element, brush, shaft, the shaft
Center, be connected with the operation handle of controller, the end face of the resistive element is equipped with voltage zero-bit exit, voltage introduces

Zero-bit exit, voltage leading-in end are arranged on outside effective travel area, and the brush is arranged on effective travel area surface, it is characterised in that
Zero compensation area, voltage adjustment area, reference voltage exit are additionally provided with the resistive element end face, the voltage adjustment area is set
Outside effective travel area, the reference voltage exit is arranged between voltage adjustment area and effective travel area, the total null voltage
Compensating basin is arranged between voltage adjustment area and zero-bit leading-in end, and the voltage adjustment area and zero compensation area use and repair carving technology
Carry out tune and consider and handle reason, when constant steady DC power supply is accessed between the voltage zero-bit exit and voltage leading-in end, every
The voltage output ratio of the reference voltage exit and brush is certain value at one gear, when the voltage of voltage leading-in end has necessarily
During fluctuation, voltage output is than constant.
Further, the resistive element is conductive plastics material, and is molded using heat pressing process.
Further, the brush uses palladium iridium alloy material.
Further, the effective travel area and the voltage adjustment equal graphite spraying resistance slurry in area.
Further, the zero compensation area surface spraying silver paste.
The angle induction element of the present invention is conductive plastic resistance body, and working face is smooth and electromagnetic compatibility is good, and brush uses
Palladium iridium alloy material, work noise is small and overlong service life, has the characteristics that linear precision is high and resolving power is high.In controller
During work, it is no longer a simple voltage signal that it, which is supplied to the signal of locomotive, but a voltage signal and reference voltage
Ratio, when the supply voltage of sensor fluctuates, output signal and reference voltage follow fluctuation, but its ratio is certain
Value.
The beneficial effects of the invention are as follows：Simple in structure, position instruction precision is high, and stable work in work, effectively compensate for
The influence that existing conductive plastics angular transducer produces locomotive operation due to mains ripple, is adapted to the load because of locomotive to become
Change big, locomotive power when across operation by sections section load allotment to power circuit of power supply difference and power supply department etc. because
Element causes to use in the case of working sensor voltage fluctuation.
