A 110V DC power supply (1) is connected with an inverter power supply (2) which is connected to a secondary winding of a high-voltage transformer (3), a primary winding of the high-voltage transformer (3) is connected with a high-voltage joint of the high-voltage apparatus on the top of the electric locomotive, an insulation resistance detector (4) is connected between the inverter power supply (2) and the high-voltage transformer (3), and the other end of the insulation resistance detector (4) is connected in parallel with a speech prompter (5) and an insulation resistance display (6). The insulation resistance of the high-voltage apparatus on the top of the electric locomotive is detected through detecting the electric current at the secondary edge of the high-voltage transformer, the insulation resistance of the high-voltage apparatus on the top of the electric locomotive is visually displayed by an LED insulation resistance display device, and the speech prompt is used for prompting the drivers that whether the high-voltage apparatus on the top has faults or not and whether the locomotive can be normally operated or not, so that the occurrence of accidents can be effectively prevented and avoided.
Description
One, technical field
The utility model relates to a kind of electric locomotive roof high voltage equipment insulation resistor detecting device.
Two, background technology
Electric locomotive roof high-tension apparatus is installed in outside the car, long-term infringement through weather extremes such as wind-engaging, sand, rain, snow, be easy to cause roof high voltage equipment insulation performance to descend, more serious situation can cause the short circuit of roof high-tension apparatus, as can not in time finding this fault and handling, then can make locomotive failure expansion even make whole contact net for power supplying paralysis, have a strong impact on the normal order of traffic safety and transportation by railroad, cause very big economic loss to country.
Three, summary of the invention
Technical problem to be solved in the utility model provides a kind of electric locomotive roof high voltage equipment insulation resistor detecting device.Whether good, and remind the driver whether fault is arranged with language if can easily detect locomotive roof high voltage equipment insulation resistance.
The technical solution adopted in the utility model is: a kind of electric locomotive roof high voltage equipment insulation resistor detecting device, it comprises DC110V power supply 1, inverter 2, high voltage potential transformer 3, it is by DC110V power supply 1, inverter 2, high voltage potential transformer 3, insulation resistance detector 4, voice prompting device 5 and insulation resistance display 6 are formed; DC110V power supply 1 is connected with inverter 2, inverter 2 is connected with the Secondary Winding of high voltage potential transformer 3, a winding of high voltage potential transformer 3 is connected with the high-voltage contact of electric locomotive roof high-tension apparatus, be connected with insulation resistance detector 4 between inverter 2 and the high voltage potential transformer 3, the other end of insulation resistance detector 4 also is connected with voice prompting device 5 and insulation resistance display 6.
The utility model compared with prior art, has following beneficial effect: by detecting the current detecting roof high voltage equipment insulation resistance on high voltage potential transformer time limit, show intuitively that by LED insulation resistance display device the insulation resistance of roof high-tension apparatus and voice suggestion remind whether fault of driver's roof high-tension apparatus, whether locomotive can normally move, and prevents and avoid the generation of accident effectively.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, embodiment:
As shown in the figure, this device is connected with inverter 2 by DC110V power supply 1, inverter 2 is connected with the Secondary Winding of high voltage potential transformer 3, a winding of high voltage potential transformer 3 is connected with the high-voltage contact of electric locomotive roof high-tension apparatus, be connected with insulation resistance detector 4 between inverter 2 and the high voltage potential transformer 3, the other end of insulation resistance detector 4 also is connected with voice prompting device 5 and leakage current display 6.
Locomotive DC 110V power supply by the DC-AC inverter be reverse into 50HZ, 100V pure sine wave AC power supplies is connected to the high voltage potential transformer Secondary Winding, produce 25kV high-voltage power supply simulation locomotive work state at a winding, come inspection vehicle to rise the insulation resistance and the pantograph state of pressure equipment by electric current, the voltage that detects a winding, the insulation resistance that shows the roof high-tension apparatus by LED, and with voice suggestion driver roof high-tension apparatus fault whether, whether locomotive can normally move.
When device work, as pantograph when rising arciform attitude, by winding of high voltage potential transformer the 100V alternating current is arranged, detect triggering LED insulation resistance display and voice prompt alarm device by a liter bow, LED shows Err, the voice suggestion detected state forbids rising bow, as pantograph when falling arciform attitude, device carries out self check, normal as self check, then the voice suggestion self check is normal, begin to detect insulation resistance, DC-AC inverter device is started working, produce the 25kV high-tension electricity by high voltage potential transformer at the roof high-tension apparatus, at this moment the insulation resistance of roof high-tension apparatus is reflected in the high voltage potential transformer Secondary Winding in proportion, trigger the insulation resistance that the insulation resistance display shows the roof high-tension apparatus by insulation resistance detector, how many insulation resistances of voice prompting device prompting roof high-tension apparatus is, as the short circuit of roof high-tension apparatus, then the insulation resistance display shows that roof high voltage equipment insulation resistance is 0000, as roof high voltage equipment insulation resistance during less than certain numerical value, then the voice suggestion insulation resistance is lower than setting, forbids rising bow, please overhaul.
Wherein inverter 2, DC-AC inverter, insulation resistance detector, voice prompting device and LED insulation resistance display that insulation resistance detector 4, voice prompting device 5, Current Display 6 select for use Baisheng Railway Science and Technology Co., Ltd., Datong to produce and sell.
