Description
Technical field
The utility model is related to power system, and in particular to a kind of outdoor Active Power Filter-APF.
Background technology
Active Power Filter-APF (APF) be it is a kind of be used for dynamic harmonic wave, the novel electric power electric device of compensating reactive power,
It can carry out quick tracing compensation to the harmonic wave of different size and frequency, why referred to as active, be relative to Passive LC filter
Ripple device, can only for the harmonic wave of Passive intake fixed frequency and size, APF can by sample load current and carry out each time it is humorous
Ripple and idle separation, control size, frequency and the phase of simultaneously active output current, and quick response, phase in payment load
Induced current, realizes dynamic tracing compensation, and can not only mend harmonic wave but also mend idle and imbalance.Outdoor active power filtering
Device is the Active Power Filter-APF used for outdoor network system, and it is widely used in cities and towns, in the power system of rural, by
Frequency converter and wave filter inside outdoor Active Power Filter-APF easily generate heat in itself, it is therefore desirable to good radiating.It is existing
Active Power Filter-APF itself be furnished with fin, the position of fin is the chamber where frequency converter and wave filter
Bottom,
Its radiating effect is still more considerable when fin is just started working for frequency converter and wave filter, but during work
Between slightly long, heat release quantitative change it is big, the radiating effect of fin there is no that what is acted on.And existing active power filtering
The both sides configuration radiating blinds of chamber where being located at frequency converter and wave filter on the full aluminum that the casing of device is generally used, casing
Window, this structure is also possible that but this for similar summer high temperature for the low function of environment heat emission performance of winter in spring outside air temperature
Its heat dispersion of hot environment is just allowed of no optimist, and particularly Active Power Filter-APF is placed under open-air atmosphere, metallic
Shell heat absorption is strong, it is weak to radiate at high temperature, and causing whole Active Power Filter-APF temperature, hurricane is high always and dissipates and does not go, so active
The frequency converter and the heat of wave filter set inside electric-power filter is even more to be difficult to disperse, it is also possible to cause Active Power Filter-APF
The damage of interior miscellaneous part.
The content of the invention
The utility model purpose is to provide a kind of outdoor Active Power Filter-APF, improves the radiating of frequency converter and wave filter
Efficiency, improves the life-span of complete machine.
In order to realize the above object the technical solution adopted in the utility model is：A kind of outdoor Active Power Filter-APF,
Including protection shell, be provided with described protection shell in upper cavity part and lower cavity part, described lower cavity part set frequency converter and
Wave filter, the both sides positioned at lower cavity part are symmetrically arranged with shutter, and passage, the bottom of passage are opened up positioned at the bottom of lower cavity part
Portion, which sets to set up to have above Air Filter, passage, sets radiator fan in supporting plate, supporting plate, set on described radiator fan
PWM control units, PWM control units are connected with the temperature sensor set in lower cavity part, rotating speed speed and the temperature of radiator fan
The height of degree sensor senses temperature is directly proportional.
It is of the present utility model to have technical effect that：The passage of setting is symmetrically set with Active Power Filter-APF lower cavity part both sides
The shutter shape put is into airflow path, specifically, radiator fan is by the cold air inspiration lower cavity part outside passage, it is cold
Hot-fluid in air driven lower cavity part is discharged by the shutter of both sides, forms bottom air draught, the cooling system of both sides air draft.This
Cooling system goes here and there wind system naturally compared to the existing shutter symmetrically opened up, and radiating efficiency is greatly improved.And the temperature set
Temperature in sensor sensing lower cavity part, by the High-low Match of sensing temperature, its rotating speed is more effectively completed lower cavity part to radiator fan
Interior radiating.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to the drawings, set in a kind of outdoor Active Power Filter-APF, including protection shell 1, described protection shell 1
Have in upper cavity part and lower cavity part, described lower cavity part and frequency converter and wave filter are set, the both sides positioned at lower cavity part are symmetrically arranged with
Shutter 2, passage 3 is opened up positioned at the bottom of lower cavity part, and the bottom of passage 3 sets Air Filter, and the top of passage 3, which is set up, to be had
Radiator fan 5 is set in supporting plate 4, supporting plate 4, PWM control units are set on described radiator fan 5, PWM control units with
The temperature sensor 6 set in lower cavity part is connected, the rotating speed speed of radiator fan 5 and the height of the sensing temperature of temperature sensor 6
It is directly proportional.
The passage 3 of setting and Active Power Filter-APF lower cavity part both sides symmetrically arranged shutter 2 formation airflow
Path, specifically, radiator fan 5 is by the cold air inspiration lower cavity part outside passage 3, cold air drives the heat in lower cavity part
Stream is discharged by the shutter 2 of both sides, forms bottom air draught, the cooling system of both sides air draft.This cooling system is compared to existing
The shutter 2 symmetrically opened up goes here and there wind system naturally, and radiating efficiency is greatly improved.And the sensing lower cavity part of temperature sensor 6 set
Interior temperature, radiator fan 5 is more effectively completed the radiating in lower cavity part by the High-low Match of sensing temperature its rotating speed.
It is preferred that, described passage 3 is located at the underface of lower cavity part upconverter and wave filter region.
Because frequency converter and wave filter are the main sources of heat in lower cavity part or even protection shell 1, passage 3 is just under
Frequency converter and wave filter region are more conducive to improve the radiating efficiency of frequency converter and wave filter in chamber portion.
Further, described temperature sensor 6 includes the first temperature sensor 6a being arranged on lower cavity part inwall, if
The second temperature sensor 6b being placed in lower cavity part on wave filter and the 3rd TEMP being arranged in lower cavity part on frequency converter
Any one sensing temperature of temperature sensor 6 in device 6c, first, second, third described temperature sensor 6a, 6b, 6c reaches
To 40 degree, PWM control units control radiator fan 5 is operated.
First, second, third temperature sensor 6a, 6b, 6c temperature monitoring probe monitors sensing lower cavity part, filtering respectively
Device, closing on for frequency converter damage lower cavity part, wave filter, the minimum temperature of frequency converter, preferably 40 degree here, are because protection shell
Not higher than 40 DEG C inside 1 lower cavity part, the work of circuit and each part is not interfered with substantially.
Further, the top of the protection upper cavity part of shell 1 sets sun-proof panel 7.
Set sun-proof panel 7 directly to reduce the probability that is exposed to the sun of outdoor Active Power Filter-APF, directly play protection active
The effect of electric-power filter internal structure particularly wave filter and frequency converter, while reducing the working strength of radiator fan 5, is improved
The service life of Hot-air fan 5.
