Abstract
The invention is an automatic phase switching device of electric power locomotive, installing a sensor on collecting bow of the electric power locomotive, when detecting the 30 m long neutral region of the insulating device in the phase section of the electric railway contact network, sending a signal to the microcomputer on the locomotive, using the microcomputer to automatically switch off the electric network current and start self-provided power supply, which can make the driver no operation and the locomotive pass through the phase section with electriciry and load and also make the contact network able to work reliably and effectively. It has characters of high reliability, simple device, more advanced and perfect technique.
Description
Affiliated technical field
The present invention relates to a kind of railway electric locomotive and automaticallyes switch by the device of electric railway electrical network phase-splitting section insulation non-Electric region.
The electric railway electrical network adopts single phase power supply, and electric system is three-phase power supply system then.Get the stream almost symmetry in order to make electric railway from the Three-phase Power Systems electrical network, electric railway has adopted segmentation to get the method for stream, be that every 20Km-25Km arranges a phase-splitting section, adjacent phase-splitting section is by different two-phase power supplies, and adjacent region has the power supply dead band about 30m.This just has the how problem by phase-separating section of electric locomotive.At present, what the most of sectionalized line of China adopted is artificial transformation approach on the car, and when namely motor supply shop was to phase-separating section, the driver will move back level earlier, closed auxiliary unit, cut off main circuit breaker,, recovered item by item by behind the phase-separating section with inertia force again.Not only driver's stress is big for this artificial transformation approach, and trivial operations is long by the non-electricity zone time, and it is many that locomotive speed descends, and if the driver careful, just be easy to chargedly by phase-separating section, cause the driving faults of phase fault.This undue phase method can not adapt to the needs of modernized railway heavy loading and high speed practical development well, has reflected that from another side research and development " automatic passing over of neutral section switching device shifter " are very urgent.
Summary of the invention:
This invention electric locomotive automatic passing over of neutral section switching device shifter provides a kind of electric locomotive that can allow not cut off the power supply by segmentation place of contact nets in electrified railways phase, can make again the reliable and effective work of contact net.Have that serviceability height, equipment are simple, technology is more advanced, more perfect, novel features more, be applicable to the electric locomotive unit fully or electricly interconnected two-shipper, the battery-driven car group is used.Have great use value and promotional value.
The technical solution adopted for the present invention to solve the technical problems is: at block of bow collector of electric locomotive a sensor is installed, detect in advance the electric railway adjacent sectional 30m of the place insulation power supply dead band in locomotive operation the place ahead, namely microcomputer sends pulse signal on the car, and microcomputer cabinet sends immediately by high-voltage switch gear and cuts off net stream and connect the instruction that redundant electrical power is got stream by electronic switch on the car.Electric locomotive is not cut off the power supply, and on-load passes through phase-separating section.When high-voltage mutual inductor on the locomotive detected non-Electric region and by contact net electricity arranged, microcomputer cabinet was sent out again instruction same and is connected online electric current and close redundant electrical power on the car, and it is complete to cross phase-splitting.N repeated usage.Like this, contact net is reliably worked effectively, can make again the driver do not have operation, locomotive at full capacity, do not underspeed, safety, the insulation power supply dead band by phase segmentation place reliably.
The invention has the beneficial effects as follows: electric locomotive driver does not have operation, locomotive at full capacity by the phase-separating section seal.Electric locomotive does not have dead electricity and presses the time, by irrelevant with speed.The electric locomotive circuit breaker is failure to actuate.Electric locomotive unit or electric interconnected two-shipper, electric motor car group all are suitable for.When contact nets in electrified railways or transformer station broke down, this electric storage device can be powered the power electricity for locomotive more than 3 hours, and electric locomotive is not rested on the trunk railway.And equipment is simple and reliable, and is easy to maintenance.
Claims (4)
1, this electric locomotive automatic passing over of neutral section switching device shifter is that a sensor is installed at the pantograph place in electric locomotive, detect locomotive operation the place ahead electric railway electrical network and divide mutually segmentation place seal (nothing is electrocuted the district), microcomputer sends signal on the car immediately, microcomputer is received to send immediately behind the signal by high-voltage switch gear and is cut off net stream and connect the instruction that redundant electrical power is got stream by electronic switch, makes the locomotive on-load that do not cut off the power supply cross phase-separating section.When high-voltage mutual inductor on the locomotive detected electrical network electricity is arranged, microcomputer cabinet sent again same order on the car, closed the deposit electric current and connected online electric current, and it is complete to cross phase-splitting, reused for N time.
2, electric locomotive automatic passing over of neutral section switching device shifter according to claim 1 is characterized in that: at block of bow collector of electric locomotive a sensor is installed, is detected in advance the electric railway contact net and divide mutually segmentation place insulation power supply dead band.
3, electric locomotive automatic passing over of neutral section switching device shifter according to claim 1 it is characterized in that locomotive installed one by the special-purpose cadmium nickel of some railways superelevation doubly, the redundant electrical power device that forms of reduced-maintenance batteries, electricity consumption when locomotive is powered the dead band by insulation.
4, redundant electrical power device according to claim 3, another feature are that this electric storage device can be powered the power electricity for locomotive more than 3 hours when contact nets in electrified railways or substation's et out of order.Electric locomotive is not rested on the trunk railway.
