Description
Technical field
The utility model relates to a kind of vehicle-used inverter off-line test device, belongs to production off-line test and experimental technique field, is applied to especially production off-line test and the experimental technique field of automobile and industrial circle inverter product.
Background technology
At present, the loading form of inverter product when production off-line test realized mainly with ohmic load or inductive load both at home and abroad, and consumed power is large.For example: for a fan-out capability, can reach the inverter product of 100kVA, roll off the production line while carrying out load testing, as used resistive load to load, energy consumption will reach 100kW, as used resistive load to load, also can only limited reduction energy consumption by setting power factor.
Summary of the invention
The utility model is realized and being loaded mainly with ohmic load or inductive load when solving existing inverter off-line test, and the problem that consumed power is large provides a kind of inverter product off-line test device of novel high-efficiency and energy-saving.
The technical solution of the utility model is achieved in that
A kind of vehicle-used inverter product off-line test device is provided, comprise industrial electrical network wave filter 1, direct supply 2, industrial electrical network wave filter 1 is connected by cable with direct supply 2, it is characterized in that, also comprise accompanying and survey inverter 4, bi-motor load 5, direct supply 2 by cable respectively with tested inverter 3 and accompany and survey inverter 4 and is connected, tested inverter 3 and accompany survey inverter 4 to be connected with bi-motor load 5 by cable; Described bi-motor load 5 comprises load motor 6 and energy recovery generator 7, load motor 6 is connected with energy recovery generator 7 rotor coaxials, described tested inverter 3 connects load motor 6 by cable, described in accompany and survey inverter 4 and connect energy recovery generator 7 by cable.
Compare traditional scheme, the loading section of the technical program is used permagnetic synchronous motor to replace resistance, has increased to accompany simultaneously and has surveyed inverter and energy recovery generator, has produced energy-efficient effect.
This novel vehicle-used inverter product off-line test device providing, can be applied to vehicle-used inverter product high-power inverter product in addition simultaneously.

Specific embodiments
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
Consult Fig. 1, the vehicle-used inverter product off-line test device providing for the utility model, it comprises industrial electrical network wave filter 1, direct supply 2, accompany and survey inverter 4, bi-motor load 5, industrial electrical network wave filter 1 is connected by cable with direct supply 2, direct supply 2 by cable respectively with tested inverter 3 and accompany and survey inverter 4 and be connected, tested inverter 3 and accompany and survey inverter 4 and be connected with bi-motor load 5 by cable, wherein, bi-motor load 5 comprises load motor 6 and energy recovery generator 7, load motor 6 and energy recovery generator 7 rotors are coaxial by mechanical connection, tested inverter 3 connects load motor 6 by cable, accompany survey inverter 4 to connect energy recovery generator 7 by cable.
The tested inverter of 300V@300A of take is example, and as adopted the traditional scheme as shown in Fig. 2, the peak power loss in test will reach 300V * 300A=90kW.
And the vehicle-used inverter product off-line test device that adopts the utility model to provide, by by power factor controlling 0.1 (power attenuation of load motor 6 and tested inverter 3 be to the maximum active power 50%), and the energy efficient recovery effect of energy recovery generator 7 (organic efficiency approximately 90%), adjust according to this, the peak power loss in test only has (300V * 300A) * 0.1 * 50%+ (300V * 300A) * 0.1 * 50% * 10%=4.95kW.
This shows, vehicle-used inverter product off-line test device energy-saving effect of the present utility model is remarkable.
