Abstract
A kind of device type fan of frequency converter component, centrifugal blower exit successively installation outlet baffle, backing plate and overhead gage from the bottom to top, the width of backing plate is less than the width of outlet damper and overhead gage, and outlet damper and overhead gage form the notch to match with frequency converter fracture type air duct lower baffle plate；Connecting terminal is installed on backing plate front end；Overhead gage is fixedly installed on the front apron of frequency converter air duct.Double more common centrifugal blowers of air intake centrifugal blower of the device type fan of frequency converter component of the utility model, use have airflow pressure bigger a little；Outlet damper and overhead gage form notch, facilitate plug；It connects the power control line of blower nearby backing plate front end placement connecting terminal, shortens the length of blower inlet-outlet line, reasonable utilization space.
Description
Technical field
The utility model relates to power electronics field more particularly to converter technology fields.
Background technique
Ac motor opens braking and a wide range of speed adjusting performance with good, in rolling mill, mine hoist, excavation
The Electric Tractions such as machine, oil-well rig, paper machine are widely used in field, and corresponding device type frequency converter also develops fast
Speed.Important component of the fan component as device type frequency converter cooling power element, it is insufficient, cooling that there is such as airflow pressures
The problems such as effect is bad, volume is excessive, difficult in maintenance.
Utility model content
For the problem that the generally existing mechanism of solving device type frequency converter fan assembly is not compact, cooling effect is bad,
The utility model provides a kind of device type fan of frequency converter component.
The utility model technical solution used for the above purpose is: a kind of device type fan of frequency converter component,
Centrifugal blower exit successively installation outlet baffle, backing plate and overhead gage from the bottom to top, the width of backing plate be less than outlet damper and
The width of overhead gage, outlet damper and overhead gage form the notch to match with frequency converter fracture type air duct lower baffle plate；Terminals
Son is installed on backing plate front end；Overhead gage is fixedly installed on the front apron of frequency converter air duct.
The outlet damper, backing plate, overhead gage, which utilize, is fixed by screws in centrifugal blower exit, on the front apron of air duct
Equipped with the semicircle gap for matching screw.
The centrifugal blower is double air intake centrifugal blowers.
Double more common centrifugal blowers of air intake centrifugal blower of the device type fan of frequency converter component of the utility model, use have
Airflow pressure it is bigger a little；Outlet damper and overhead gage form notch, facilitate plug；Connecting terminal is placed into backing plate front end
It connects the power control line of blower nearby, shortens the length of blower inlet-outlet line, reasonable utilization space.
Detailed description of the invention
Fig. 1 is utility model device type fan of frequency converter component main structure figure.
Fig. 2 is utility model device type fan of frequency converter component three-dimensional structure diagram.
Fig. 3 is utility model device type fan of frequency converter component assembling assumption diagram.
In figure: 1, centrifugal blower, 2, outlet damper, 3, overhead gage, 4, backing plate, 5, screw, 6, connecting terminal, 7, before air duct
Baffle, 8, air duct lower baffle plate.
Specific embodiment
The device type fan of frequency converter modular construction of the utility model is as depicted in figs. 1 and 2, by double air intake centrifugal blowers 1,
The composition such as fan outlet baffle 2, fan assembly overhead gage 3, fan assembly backing plate 4, connecting screw 5, connecting terminal 6, centrifugation
Successively installation outlet baffle 2, backing plate 4 and overhead gage 3, outlet damper 2, backing plate 4, overhead gage 3 are sharp from the bottom to top in blower 1 exit
It is fixed on 1 exit of centrifugal blower with by screw 5, air duct front apron 7 is equipped with the semicircle gap for matching screw 5,
The width of backing plate 2 is less than the width of outlet damper 2 and overhead gage 3, and outlet damper 2 and overhead gage 3 are formed and frequency converter fracture type
The notch that air duct lower baffle plate 8 matches；Connecting terminal 6 is installed on 4 front end of backing plate；Overhead gage 3 is fixedly installed in frequency converter air duct
On front apron 7.
Use double more common centrifugal blowers of air intake centrifugal blower have the advantages that airflow pressure is bigger, by outlet damper 2,
Backing plate 4, overhead gage 3 are fixed at fan outlet together using connecting screw 5, by the width design of backing plate 4 at being slightly less than baffle
Width, so that outlet damper 2 and overhead gage 3 is formed notch, facilitate plug.Connecting terminal 6 is placed into backing plate front end simultaneously, makes wind
The power control line of machine connects nearby, shorten the length of blower inlet-outlet line, reasonable utilization space.
As shown in figure 3, by fan assembly, oblique 45 ° of insertions are formed by air duct front apron 7 and air duct lower baffle plate 8 in the direction of the arrow
Slideway, wherein air duct lower baffle plate 8 is designed to fracture type, mutually agrees with the notch of fan assembly；It is opened on air duct front apron 7 simultaneously
There is semicircular gap, the position of fixed screw 5 is got out of the way, makes entire fan assembly plug freely.Using two screws by wind
Machine overhead gage 3 and air duct front apron 7 are fixed, so that it may fix entire fan assembly with frequency converter, Operation and Maintenance is simple, convenient for more
Ventilating fan component.
