Description
Technical field
The utility model relates to a kind of system test equipment, relates in particular to the system test equipment of frequency converter.
Background technology
The system test of frequency converter generally needs through several test links such as vdct, alternating voltage test and functional tests.Vdct need connect DC voltage to frequency converter, and the alternating voltage test need connect alternating voltage to frequency converter, and functional test need connect motor to frequency converter.Because can not carry out above-mentioned several kinds of tests simultaneously, therefore, whenever once to test, frequency converter all need carry out different connections to realize test.The connection of change frequency converter that so just must be frequent has caused the low of work efficiency.
The utility model content
The technical matters that the utility model will solve is that the system test link that overcomes owing to frequency converter needs the frequent connected mode that changes to cause the low problem of work efficiency, and proposes a kind of system test equipment of frequency converter.
For solving the problems of the technologies described above, the utility model proposes a kind of system test equipment of frequency converter, comprises a test fixture, a test cabinet, a controlling computer, a display screen, a load motor and a load motor proving installation; Test fixture be provided with one be used to place frequency converter the test fixture main body, test fixture main body one end is provided with a plug, plug is connected with the terminal row of frequency converter through multiple conducting wires, also is provided with many contact pins on the plug; The test cabinet is the box like structure of a side opening; Its open side is provided with the cabinet door of closed test cabinet internal cavities; The inwall of test cabinet relative cabinet door is provided with a socket, and socket links to each other with load motor with external power source respectively, also be provided with on the socket with plug on contact pin mate the slot of grafting; Load motor connects the load motor proving installation, and the load motor proving installation all links to each other with controlling computer with display screen.
Preferably; Controlling computer comprise a primary controller, in order to the data acquisition unit, of the test data of gathering frequency converter in order to the storer of store test data and the dispensing device that test data is outwards sent; Data acquisition unit, storer and dispensing device all link to each other with primary controller, and test socket cashier's office in a shop links to each other with data acquisition unit.
Preferably, the bottom surface of test fixture main body is provided with guided way, and the diapire inside surface of test cabinet is provided with the guide chute that cooperates guided way.
Compared with prior art; The beneficial effect of the utility model comprises: the setting of the utility model test clamp and test cabinet; Only need to change being connected of test cabinet and outside input and output; And the connection that does not need the frequent change frequency converter just can realize the test of different links, has improved work efficiency.
Description of drawings
Fig. 1 is the system test equipment principle block diagram of the utility model frequency converter.
Embodiment
For principle and the structure that further specifies the utility model, combine accompanying drawing that the preferred embodiment of the utility model is elaborated at present.
Consult Fig. 1, the system test equipment of the utility model frequency converter comprises a test fixture 2, a test cabinet 3, a controlling computer 4, a display screen 5, a load motor 6, a load motor proving installation 7 and external power source 8.
Controlling computer 4 comprise a primary controller, in order to the data acquisition unit, of the test data of gathering frequency converter 1 in order to the storer of store test data and the dispensing device that test data is outwards sent.Data acquisition unit, storer and dispensing device all link to each other with primary controller, and data acquisition unit also links to each other with the socket of test on the cabinet 3.
When test cabinet 3 is used as the vdct cabinet; The external power source 8 that links to each other with socket is DC voltage; Whether the set-point that changes DC voltage can be used for test frequency converter 1 and under the DC voltage of certain limit, works normally, and the operational data under the given voltage of difference is stored in the storer of controlling computer through data acquisition unit.
When test cabinet 3 is tested cabinet as alternating voltage; The external power source 8 that links to each other with socket is alternating voltage; Whether the set-point that changes alternating voltage can be used for test frequency converter 1 and under the alternating voltage of certain limit, works normally, and the operational data under the given voltage of difference is stored in the storer of controlling computer through data acquisition unit.
When test cabinet 3 is used as the functional test cabinet; Push the test button on the test cabinet 3 cabinet doors; May command frequency converter 1 drive load motor 6 is realized just changeing, reversing or is stopped and function such as stop; Whether load motor proving installation 7 is realized just changeing, reverses, is stopped and stop etc. according to the instruction of test button in order to detect load motor, and testing result is transferred to controlling computer 4.
After the test of above-mentioned each test cabinet was accomplished, the data acquisition unit of controlling computer 4 was gathered the test data of frequency converter 1, and is stored in the storer, and then, in the time of setting, controlling computer 4 control dispensing devices send to test data on the server.
Compared with prior art; Adopt a kind of system test equipment of frequency converter, the setting of test clamp and test cabinet only needs to change being connected of test cabinet and outside input and output; And do not need just can realize the test of different links to the connection of frequent change frequency converter, improved work efficiency.
The above is merely the preferable possible embodiments of the utility model, and the protection domain of unrestricted the utility model.The equivalent structure that all utilization the utility model instructionss and accompanying drawing content have been done changes, and all is included in the protection domain of the utility model.
