Description
Technical field
The present invention relates to active power filtering(APF)Building block technique field, more particularly to it is a kind of with natural heat dissipation ability
APF modules.
Background technology
In recent decades, developing rapidly with Power Electronic Technique, high-power switch device is in modern industry and daily
It is widely used in life, such as:Electronic power conversion device, electric arc furnaces etc..So that line voltage and current waveform production
Serious distortion has been given birth to, to substantial amounts of higher hamonic wave is filled with utility network, has caused the quality of power supply constantly to decline, has a strong impact on
The normal operation of electrical equipment, as caused by harmonic pollution various failures and accident also constantly occur.Therefore, power system is humorous
The seriousness of ripple harm causes the great attention of people.Either from the point of view of ensureing that power system is normally run, still
In terms of the normal work angle of user power utilization equipment, harmonic wave is effectively administered, harmonic content is limited within allowed band, is given
Power network builds a good electric circumstance, i.e. " green network ", improves the quality of power supply and has become present electric power and grinds
Studying carefully field must solve and the problem of primary study.Therefore, it is necessary to take effective measures to suppress their influence.
Traditional active power filtering(APF)Module generally uses the radiating mode of forced air cooling, such as Chinese patent
It is exactly to be dried and radiated by air flow using cooling blower mode in ZL201520536488.X.But, dissipated using this
Hot mode, during fan high-speed rotation, can produce larger noise, and the work and life on people around bring certain influence;Separately
Outside, in fan rotation process is total, due to needing ventilation, outside dust can enter fan and module cabinet inside therewith, and
It is attached on the Air Filter of air outlet, after long-play, because fan and Air Filter are covered with dust all over, can gradually influences fan
Radiating efficiency;Dust or foreign matter enter after module cabinet inside simultaneously, also can be to sensitive components, and such as IGBT pin can
Impacted by property, reduce the service life of whole module.
The content of the invention

The upper interior surface for being close to the cabinet is installed.
Further, the APF modules with natural cooling ability, can also include pre-charge resistance, the precharge
Install on the lower interior surface top that resistance is close to the cabinet.
Compared with prior art, the beneficial effects of the invention are as follows:
1st, natural heat dissipation mode is employed, in the premise for ensureing effectively to radiate to the switch electric components of big caloric value
Under, it is to avoid APF modules are radiated using fan or cooling blower etc., heat dissipating mass and space is not only reduced, also subtracts
The volume and weight of light APF modules, makes that the structure of device is compacter, and outward appearance is more compact and flexible.In addition, cabinet can be taken
Seal Design, makes APF inside modules components be in sealing state, it is to avoid the entrance of dust and other impurities, it is adaptable to field ring
Border.
2nd, using the radiating mode of natural cooling, fan air blast cooling is eliminated, when APF modules are run, noise is small, improved
The service life of equipment, the workload of manual maintenance greatly reduces.
