The method is mainly characterized in that a junction filter is mounted on a shielding cavity of the power generating set; a shielding housing of the junction filter and the shielding cavity of the power generating set achieve effective shielded mounting; the junction filter is internally provided with a plurality of filtering channels according to electromagnetic spectrum characteristics of the interference sources; electromagnetic field and conduction spectrum characteristics generated by the interference sources of the power generating set can be acquired by tests in an electromagnetic compatibility laboratory; and acquired electromagnetic interference spectrum characteristic data can serve as a basis for designing the junction filter. The method has the technical effects that field radiation interference of the set to external power utilization sensitive equipment is inhibited, and conducted interference of the set to the external power utilization sensitive equipment is prevented by a junction filtering scheme of the silent power generating set.
Description
Technical field
The present invention relates to a kind of method that suppresses interference source, be specifically related to a kind of method that suppresses the inner multiple interference sources of mute generator group.
Background technology
Mute generator group screen covers inside cavity and has multiple interference sources (as generator, charging module etc.).The wire of these interference sources by power line, transmission of signal etc. by electromagnetic interference Energy Transfer to unit shielding cavity outside, thereby make unit produce electromagnetism Interference and electromagnetic field radiation interference (wire to outfield radiation) to the sensitive equipment of electricity consumption.Therefore, must carry out the method effectively suppressing by a kind of interference electromagnetic energy that can produce multiple interference sources of research.
Summary of the invention
The object of the present invention is to provide a kind of method that suppresses mute generator group internal interference source, by installing filter in generating set, the interference electromagnetic energy of interference source output obtains larger decay in filter, can effectively suppress electromagnetism Interference and electromagnetic field radiation interference that generating set produces electricity consumption sensitive equipment.
The present invention is achieved like this, a kind of method that suppresses mute generator group internal interference source, it is characterized in that: the method is mainly that a junction filter is installed on the shielding cavity of mute generator group, the shield shell of junction filter self and the shielding cavity of generating set are realized effectively shielding and are installed; Electromagnetic spectrum characteristic for each interference source in described junction filter is provided with multiple filtering channels, the electromagnetic field that each interference source of described generating set produces and conduction spectral characteristic can be obtained by the test in electromagnetic compatibility laboratory, and the various electromagnetic interference spectral characteristic data of obtaining can be used as the foundation of composite design filter.
The shield shell of junction filter of the present invention self is connected and is realized closed shield installation by flange, conducting resinl and securing member with the shielding cavity of unit.
The present invention adopts the scheme of installation junction filter can simplify the shielding construction of multi-channel filter, and the shielding cavity of being convenient to junction filter self shield shell and unit is realized closed shield installation.
The present invention due to install after junction filter and the shielding cavity of unit formed effective electromagnetic-field-shielded, because having obtained effective conduction by multi-channel filter, the conducted interference that interference source produces suppresses again, the interference electromagnetic energy that therefore both can stop the multiple interference sources in shielding cavity to practice midwifery raw by field radiation straight is leaked to outside, can stop again the conducted interference electromagnetic energy that interference source sends by cable to leak.
Technique effect of the present invention is: the combined filter scheme of the present invention by mute generator group not only suppressed field radiated interference that unit produces outside electricity consumption sensitive equipment but also stoped the conducted interference of unit to outside electricity consumption sensitive equipment generation.
Brief description of the drawings

Embodiment
Below in conjunction with brief description of the drawings, embodiments of the invention are described in further detail, but the present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof, all should list protection scope of the present invention in.
As shown in Figure 1, the present invention comes work and enforcement like this, a kind of method that suppresses mute generator group internal interference source, the method is mainly that a junction filter 1 is installed on the shielding cavity of mute generator group, junction filter 1 passes through flange with unit shielding cavity 2, conducting resinl and securing member can be realized closed shield and install, the electromagnetic energy spectral characteristic that each interference source 3 in unit shielding cavity 2 produces can be obtained by the test in electromagnetic compatibility laboratory, the various electromagnetic interference spectral characteristic data of obtaining can be used as the foundation of composite design filter 1.Junction filter 1 after installation has formed effective electromagnetic-field-shielded with the shielding cavity 2 of unit, the conducted interference that interference source 3 produces has obtained effective conduction by multichannel junction filter 1 and has suppressed, the interference electromagnetic energy that therefore both can stop interference source 3 to produce by field radiation is leaked to outside, can stop again the conducted interference electromagnetic energy that interference source 3 sends by cable to leak.
Operation principle of the present invention: the junction filter 1 after installation has formed effective electromagnetic-field-shielded body with the shielding cavity 2 of unit, the conducted interference that interference source 3 produces has obtained effective conduction by multichannel junction filter 1 and has suppressed, therefore the shielding cavity 2 of unit can stop the interference electromagnetic energy that interference source 3 produces by field radiation to be leaked to outside, and junction filter 1 can stop the conducted interference electromagnetic energy that interference source 3 sends by cable to leak.
