Description
Technical background
The utility model relates to electric locomotive stringing automatic power equipment, specifically is a kind of device that adopts carrier signal control electric locomotive stringing auto-power-cutting.Be specially adapted to not have under the coal mine occasions such as the stringing electrical locomotive running region of gas, coal dust explosion hazard or ground rail crossing infall.
Background technology
Present electric locomotive stringing power supply has three kinds of situations: the one, and whether no matter have electric locomotive to travel, stringing has always.The shortcoming of this method is that the workman is easy to generate electric shock accidents when work, and electric leakage and stray current loss are arranged.The 2nd, stringing is carried out segmentation and adds switch, when arriving the stringing zone, electric locomotive manually send electricity, when leaving, electric locomotive manually cuts off the power supply.The shortcoming of this method is to have the special messenger to guard switch, causes personnel's significant wastage.The 3rd, stringing is carried out segmentation and adds main control computer, emitter is housed, when electric locomotive arrives this section when regional on electric locomotive, emitter emission carrier signal, main control computer are received coil adhesive behind the signal, and stringing has, after electric locomotive left, the main control computer coil disconnected, and stringing does not have.The shortcoming of this method is that the signal transmission is unstable, can not Long-distance Control.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of device with digital carrier signal control electric locomotive stringing auto-power-cutting is provided.Electric blocking when realizing section occupied takes place to prevent accidents such as electric locomotive knocks into the back, collision.When no locomotive passes through, the stringing no-voltage, the electric shock accidents that reduces a staff takes place, and improves security effectiveness.
The utility model is realized with following technical scheme: a kind of device with digital carrier signal control electric locomotive stringing auto-power-cutting, comprise multiple stage electric locomotive stringing, incision position at per two sections electric locomotive stringings links together the electric locomotive stringing with collets, it is characterized in that being equipped with on electric locomotive the digital carrier signal emitter; Every section stringing section is provided with a receiver and an isolation change-over swith, the connection terminal K1 power connection bus of isolating change-over swith, connection terminal K2 inserts stringing section I, connection terminal K3 inserts the connection terminal J3 of receiver, and connection terminal K4 inserts the isolation change-over swith connection terminal K1 of next electric locomotive stringing section; The connection terminal J5 of receiver inserts stringing section I, connection terminal J2 ground connection; On receiver, be connected be used to measure electric locomotive by the time current signal current sensor.
Parking lot and power failure head of district phase keep power down mode, and when electric locomotive entered this stringing section, the auto-power-cutting switch device was discerned by sensor signal, realize auto-power-cutting.After locomotive crossed the district that has a power failure, the district's time-delay that has a power failure had a power failure, and electric supply installation recovers power down mode.This method of supplying power to has improved the safety of stringing power supply greatly, is the very high electric supply installation of a kind of safety rate.Transmitter supply is directly supplied by electric locomotive, avoids emitter battery to occur and does not have electric out-of-action phenomenon; Use the digital carrier technology, the signal transmission is more stable, and transmission distance can reach 1500 meters, need not set up contact or sensor, as long as at locomotive the carrier signal emitter is installed, promptly send automatically after the power supply master controller is received digital carrier signal.Be specially adapted to not have under the coal mine occasions such as the stringing electrical locomotive running region of gas, coal dust explosion hazard or ground rail crossing infall, the electric shock accidents that reduces a staff takes place, and improves security effectiveness.
The beneficial effects of the utility model are:
1) at unoccupied section air wire no-voltage, improved this section staff personal safety coefficient, reduced the generation of electric shock accidents.
2) air wire electric leakage and stray current have been reduced.
3) reduce the stringing that due to leakage current causes and the oxidation corrosion of auxiliary facilities (pipeline, track), prolong stringing service life.
4) according to system's locking requirement, if occupied section has locomotive, an other locomotive is not listened commander, makes a forcible entry into, and then can directly cut off the electricity supply to stop this locomotive driving.
5. remote controlled: as can to pass through industrial bus cable connection receiver, power supply state and supply current signal are uploaded to upper main control computer dynamically to be shown, the dispatcher can understand down-hole each section of stringing electric power thus supplied by upper computer, and can send electricity and outage with mouse control, also can know every electric locomotive probably where simultaneously at upper computer, can be by this function to overall understanding of stringing electric power thus supplied and control.
