It sets outside screened room, rotary load is connect by the first connecting shaft with compressor, and compressor passes through fluid circuit and fluid motor
Connection, fluid motor are connect by the second connecting shaft with motor load, and fluid circuit passes through screened room.
By above scheme as it can be seen that the rotary load being placed in the darkroom EMC i.e. screened room is connected by connecting shaft and compressor
It connects, and drives compressor that can be connected to outdoor by shielding tunnel by fluid circuit, and driven in outdoor connecting fluid motor
Drive motor load rotation, it is seen that mechanical energy is transferred to outdoor by compressor and fluid circuit, dexterously using compressor
Energy is transmitted to outdoor by fluid application, is reconverted into electric energy, electromagnetic load has both been avoided and has led to the problem of EMC interference,
The expensive problem of the nonmetallic connecting shaft of mechanical transmission process is avoided again, so that the test macro of this case not only measuring accuracy
It is high and cost is relatively low.
Further scheme is that fluid circuit is made using non-magnet material.
Further scheme is that plastic conduit, rubber tubing or nylon pipeline can be used in fluid circuit.
Further scheme is that fluid circuit arranges that fluid circuit includes output pipe and input pipe in circulation line
Road, output pipe and intake line are each passed through screened room, and output pipe and intake line are connected to compressor and fluid
Between motor.
Therefore fluid circuit is made by non-magnet material can be improved measuring accuracy.
Further scheme is that EMC test macro is additionally provided with depletion load, depletion load and motor outside screened room
Load connection.
Therefore the consumption that depletion load improves energy can be in addition added, more kinds of test applications are provided for this programme.
Further scheme is that for fluid circuit for conveying gas, fluid motor is air motor.
Further scheme is that for fluid circuit for conveying liquid, fluid motor is hydraulic motor.
Therefore fluid is that the purpose of this utility model can be achieved in gas or liquid, gas or liquid are non-lead
Magnetic medium guarantees to meet requirement of the EMC test to ambient noise.
Detailed description of the invention
Fig. 1 is the system schematic of the utility model EMC test macro.
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.
Specific embodiment
Referring to Fig.1, the EMC test macro of the utility model is suitable for rotary load 11, rotary load 11 can for motor or
Generator, as long as the applicable and the utility model of revolving load.EMC test macro includes screened room 10, rotates and bear
Carry the 11, first connecting shaft 12, compressor 13, fluid circuit, fluid motor 15, the second connecting shaft 16, motor load 17 and consumption
Load 18, screened room 10 also can be the darkroom EMC, and rotary load 11, the first connecting shaft 12 and compressor 13 are arranged in screened room 10
Interior, rotary load 11 is connect by the first connecting shaft 12 with compressor 13, and the first connecting shaft 12 is using conventional transmission mechanism
Can, the transmission of special material is not needed, the transmission of the rotation and connecting shaft that are occurred by rotary load 11, then band dynamic pressure
The work of contracting machine 13.
Fluid motor 15, the second connecting shaft 16 and motor load 17 are arranged outside screened room 10, and compressor 13 passes through fluid
Pipeline is connect with fluid motor 15, and fluid circuit is made using non-magnet material, and plastic conduit, rubber can be used in fluid circuit
Plastic pipe or nylon pipeline, fluid circuit arrange that fluid circuit includes output pipe 141 and intake line 142 in circulation line,
