3, workshop can not easily be installed to, the inverter that batch testing is produced.
Chinese Patent Application No. 201110043797.X relates to one for testing the test platform of photovoltaic combining inverter property indices.This test platform uses photovoltaic battery array analog power as the input source of inverter, instead of original real photovoltaic battery array; Electrical network simulated behavior power supply is used to replace high-power resistance load.Photovoltaic battery array analog power can arrange the weather conditions such as required illumination, environment temperature, wind speed easily, exports satisfactory V-I curve, overcomes true photovoltaic battery array uncontrollable factor many, the shortcoming of installation and maintenance inconvenience.Electrical network simulated behavior power supply can the feature such as simulating grid voltage, frequency, background harmonics, the serviceability of inverter under different electric network states can be detected, the output back electrical energy of inverter can also be returned public electric wire net by electrical network simulated behavior power supply in addition, reduces electric energy loss.
China Patent No. ZL201220139826.2 provides a kind of grid-connected micro-inverter automatic test platform, comprising: photovoltaic array analog power; Power analyzer, the output terminal of photovoltaic array analog power is connected by the input end of micrometer inverter by power analyzer; Programmable AC Power Source, its output terminal is connected by the output terminal of micrometer inverter by power analyzer; Control system, is connected with photovoltaic array analog power, power analyzer and Programmable AC Power Source respectively.This utility model can implement comprehensive selectable automatic test to the properties of grid-connected micro-inverter.
Summary of the invention
The purpose of this utility model is to provide a kind of middle low power inverter performance automatic test platform.
The purpose of this utility model is achieved in that a kind of middle low power inverter performance automatic test platform, there are testing power supply, power analyzer, controlled by PC, inverter and associated test devices are contained on a testing jig, described associated test devices comprises testing power supply, power analyzer, load resistance box, be placed in different sashes respectively, this testing jig assembles a PC, control testing power supply and power analyzer respectively, instruction is sent to the test event of inverter, wherein, described testing power supply is AC source and DC source.
On such scheme basis, described PC uses 485 or other order wire connection AC source, DC source, power analyzer and inverter.
Described AC source is connected with electrical network.
Superiority of the present utility model is:
1, by inverter and associated test devices device on a testing jig, as a whole test platform, take up an area little, save space.
2, this platform is furnished with PC, can automatically control all peripheral test apparatus.
3, this platform is according to the technical indicator of inverter, is completed the test of every technology by operating personnel on PC, as comprised: efficiency, harmonic wave, power factor, mistake/under-frequency point etc.
4, this platform can directly be assembled to inverter workshop, can save the performance test time of product (inverter).
5, this platform operations is simple, and measuring accuracy is high, can improve work task efficiency greatly.
6, in addition, the AC source of this platform (can to electrical network feed) be connected with electrical network, and the function of inverter own is by converting direct-current power into alternating-current power.So the test electric energy that testing power supply provides by inverter, be transmitted back to electrical network again.Therefore, the electric energy loss of this platform is only cable consume.
