At present; Because the high-voltage power supply rated voltage of electric locomotive is 25KV; Allowed band is 19-29KV, and immediate general industry electricity consumption grade is 30KV, so electric locomotive maintenance unit must introduce the Railway Special electrical network; Or the manufacturing high-tension transformer, the high-potting project testing after overhauling.In frequency of utilization under the not high and maintenance place unfixed relatively condition, more than two kinds of means long, problem such as relative cost is high, the powered operation formality is numerous and diverse of construction period all can appear.
Summary of the invention
The purpose of the utility model is to above-mentioned deficiency, and a kind of the savings construction period that proposes, reduces cost, and saves the labour, increases work efficiency, and overhauls the no net height compression testing device that electric locomotive provides high-potting for flowing.
The technical solution of the utility model is: electric locomotive does not have the net height compression testing device and is: the 380V alternating current connects the low pressure winding of automobile-used main-transformer through A.C. contactor; The high pressure winding output 25KV high pressure of main-transformer is in series with controller on the coil of A.C. contactor.
Controller described in the technical solution of the utility model is that switch knob and the opening button of controller on the car back of connecting with the coil of safety interlock switch, A.C. contactor connects automobile-used 110V direct supply through rising the bow switch.
Safety interlock switch described in the technical solution of the utility model is to be connected on the automobile-used pantograph lift valve airduct by three-way pipe, and the setting pressure relay constitutes on the three-way pipe, and the pressure switch interlocking contact is connected onboard in the controller.
The test ultimate principle of the utility model does; No net height compression testing device is that electric locomotive provides high-power single-phase 380V specified experiment work power supply; Through the power output lead, be connected to the auxiliary winding of locomotive main transformer, produce single-phase 25KV high pressure; And the required nominal operation power supply of each bogie, add the basic high-voltage performance tests of electric locomotive such as stream to accomplish each frame backup system, test no-load voltage, low level.Before this test unit has solved the positive thread test of electric locomotive; The basic high-potting project testing of each item that does not have electric locomotive under the single-phase 25KV high pressure Railway Special electrical network; And three phase electric machine test phase sequence problem, it is consistent with the main track test findings to have guaranteed that test hauling ability index and three phase electric machine turn to.Factories and miness, the enterprise that can be widely used in not having the special-purpose electrical network of railway carry out various model railways and test with the electric power locomotive inspection and repair.
The no net height compression testing device of the utility model need not introduced the Railway Special electrical network or make big merit convertor transformer, has saved a large amount of expenses, and the construction period is short; Conveniently moving; Improved labour productivity, used one year over, function is feasible, safe and reliable, economical savings.
