Abstract
The name of the invention is a meshless high-voltage test device of an electric locomotive, and relates to a device for generating single-phase 25KV of high voltage by an auxiliary winding of a main transformer of the electric locomotive and testing the high voltage performance of the electric locomotive. The meshless high-voltage test device mainly solves the problem that a dedicated railway network needs to lead in when the electric locomotive is overhauled, or the problems of high construction cycle, high cost and sundry power supply operating procedures when a 25KV of high-voltage transformer is manufactured to carry out a high-voltage test project. In the meshless high-voltage test device of the electric locomotive, 380V of alternating current is connected to a low-voltage winding of the main transformer of the locomotive through an alternating current contactor; a high-voltage winding of the main transformer of the locomotive outputs 25KV of high voltage, and a controller is connected with a coil on the alternating current contactor in series. A 380V of rated test work power supply is connected to an auxiliary winding of the main transformer of the locomotive, and generates 25KV of single-phase high voltage for a high-voltage test of the locomotive. The meshless high-voltage test device disclosed by the invention is adopted; and the dedicated railway network does not need to lead in or a high-power transformer does not need to manufacture. Therefore, a lot of costs are saved, and the meshless high-voltage test device is short in construction cycle, convenient to move, safe and reliable.
Description
Technical field
The invention belongs to electric locomotive and make the repair test technical field, relate to specifically a kind of auxiliary winding of electric locomotive main transformer that utilizes and produce single-phase 25KV high pressure, the device that the basic high-voltage performance of electric locomotive is tested.
Background technology
At present, because the high-voltage power supply rated voltage of electric locomotive is 25KV, allowed band is 19-29KV, immediate general industry electricity consumption grade is 30KV, so electric locomotive maintenance unit must introduce the special-purpose electrical network of railway, or the manufacturing high-tension transformer, the high-potting project testing after overhauling.In frequency of utilization under the not high and maintenance place relatively unfixed condition, more than two kinds of means long, the 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 objective of the invention is for above-mentioned deficiency, and a kind of the savings construction period that proposes, reduce cost, the saving labour increases work efficiency, for the mobile overhaul electric locomotive provide high-potting without the net height compression testing device.
Technical solution of the present invention is: high-voltage testing device without electric network for electric locomotives is: the 380V alternating current connects the low pressure winding of automobile-used main-transformer by A.C. contactor, the high pressure winding of main-transformer output 25KV high pressure is in series with controller at the coil of A.C. contactor.
Controller described in the technical solution of the present invention is to connect automobile-used 110V direct supply by the rising bow switch after the switch knob of controller on the car and opening button are connected with the coil of safety interlock switch, A.C. contactor.
Safety interlock switch described in the technical solution of the present invention is to be connected on the automobile-used pantograph lift valve airduct by three-way pipe, and the setting pressure relay consists of on the three-way pipe, and the pressure switch interlocking contact is connected onboard in the controller.
Test ultimate principle of the present invention is, provide the specified experiment work power supply of high-power single-phase 380V without the net height compression testing device for electric locomotive, 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 finish each frame backup system, test no-load voltage, low level.Before this test unit has solved the positive thread test of electric locomotive, every basic high-potting project testing without the electric locomotive off the net of single-phase 25KV high pressure railway Special electric, and three phase electric machine test Problem of phase sequence, 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 without railway Special electric net carry out various model railways power locomotive inspection and repair tests.
Of the present inventionly need not introduce the special-purpose electrical network of railway or make large merit convertor transformer without the net height compression testing device, save a large amount of expenses, the construction period is short, conveniently moving, improved labour productivity, used one year over, function is feasible, safe and reliable, economical saves.
