Background technology

For newly-built and operating high voltage substation, need carry out engineering commissioning test or operating preventive trial to high voltage electric equipment.When high voltage electric equipment is carried out various tests and test, existing method is that many high-precision instruments are transported to respectively near the transformer station by vehicle etc., then these instruments being transported to suitable place measures, and the data that will at every turn measure note respectively, import computing machine afterwards again and integrate; Yet, because high voltage electric equipment is of a great variety, test wiring complexity, the personnel that test needs strong working experience operate, and when using instrument separately, instrument only shows current test result, can't carry out effective discriminatory analysis, the time that delays to pinpoint the problems immediately to the result; The processing of test figure lacks special conversion, analysis, statistical software, also fails to include in the department information automated system, and the degree of integration of system is very low.

In addition, because the volume and the quality of various testing tools all differ greatly, if spuious arrangement in the transportation is easy to because extruding or jolting of haulage vehicle are caused damage; Measuring and test site, get off if each testing tool all carried, move back on the transport vehicle again after test finishes, because equipment is numerous and jumbled, handling process will be very loaded down with trivial details, use very inconveniently, especially under comparatively abominable natural conditions (for example period in severe winter of China the Northeast), carrying work is easy to cause the damage of instrument; On the other hand, all tests are all carried out outdoor, consider that high voltage substation generally all is in the remote point, and when weather was comparatively abominable, the working environment of tester and instrument necessity can not be protected, and the precision of test data is difficult to guarantee.

In sum, the present invention aims to provide a kind of system combination degree height, easy to use and can guarantee transformer station's electric testing car of tester's working environment.

Summary of the invention

The purpose of this utility model is that design provides a kind of system combination degree height, easy to use and can guarantee transformer station's electric testing car of tester's working environment.

For achieving the above object, transformer station's electric testing car that the utility model provides comprises driving and occupant area, partition wall and testing equipment and master control district, partition wall separates driving and occupant area with testing equipment and master control differentiation, the independent rack that several settle test apparatus and annex is set in testing equipment and the master control district, each test apparatus and computing machine link, and form complete test and test macro.

The utility model provide electric testing car with orderly being installed in the car body of various instrument and equipments, each test cell links by communication interface and computing machine, constitutes multi-functional automatization test system.In the process of test and test, can pilot system and tested equipment be linked by outside lead, finish experiment work automatically by computer control; Also test cell can be separated (especially under the Hi-pot test environment) with system, as independently instrument use, finish experiment work by panel operation, test result can be input in the computing machine and handle, store, system combination degree height, purpose easy to use have been reached, and,, also can guarantee tester's working environment even under the atrocious weather condition owing to be provided with air-conditioning system in the car.
