Abstract
The utility model discloses a frequency converter chamber ventilation structure, and belongs to the technical field of the electric power industry. An air collecting housing is installed above a frequency converter fan. A lower portion of a wall at one side of a frequency converter chamber is provided with an air inlet. An upper portion of a wall at the opposite side of the frequency converter chamber is provided with an air outlet. The air outlet is provided with an axial-flow blower fan and is connected with the air collecting housing through an air channel. Through additionally arranging the axial-flow blower fan, the air collecting housing, the air channel, the air inlet and the air outlet in the frequency converter chamber, the heat generated during the operation of a frequency converter is directly pumped outdoor, the work environment of the frequency converter is improved, and the reliability of the operation of the frequency converter is improved; and the operation time of an air conditioner is reduced, and the cost is reduced.
Description
Technical field
The utility model relates to power industry, relates in particular to a kind of Transducer Room aeration structure.
Background technology
Frequency converter is one of common electric equipment of power industry; to be the on-off action that utilizes power semiconductor device be transformed to the electric energy control device of another frequency with power frequency supply for it, it can realize to AC induction motor soft start, frequency control, raising running accuracy, change power factor, the overcurrent/overvoltage/functions such as overload protection.
Can distribute a large amount of heat energy during frequency converter work, therefore need to carry out room temperature lowering to Transducer Room, at present the main mode that adopts the air conditioner refrigerating cooling.Usually, the air-conditioning that the frequency converter indoor location 2-4 platform of primary air fan is 10, the frequency converter indoor temperature remains on about 28 degree, guarantees the frequency converter normal operation.Yet there is more defective in the mode of this air conditioner refrigerating cooling: (1) Transducer Room air-conditioning needs are operation throughout the year, and power consumption is very large; (2) operation of air conditioner 2 years is by job failure often occurring, and maintenance capacity, maintenance cost are higher; (3) in case air-conditioning breaks down, the normal operation of frequency converter will be had a strong impact on.
The utility model content
The purpose of this utility model provides the Transducer Room aeration structure that a kind of cost is low, can guarantee the frequency converter normal operation.
For achieving the above object, the utility model adopts following technical scheme:
A kind of Transducer Room aeration structure, wind gathering cover is installed above fan of frequency converter, be provided with air inlet in Transducer Room one side walls bottom, at Transducer Room side walls top be provided with air outlet, this air outlet is provided with axial flow blower and links to each other with described wind gathering cover by the air channel.
Further, described air inlet is provided with filter screen.
Further, described air inlet is provided with outer cover plate.
Further, described air inlet is apart from ground 20-30cm.
Further, described air outlet is provided with outer closure plate.
Further, described air outlet is apart from Transducer Room top 25-35cm.
Further, the diameter of described axial flow blower is 660mm.
Further, described wind gathering cover is apart from frequency converter 30-40cm.
The Transducer Room aeration structure that the utility model provides is by setting up axial flow blower, wind gathering cover, air channel, air inlet and air outlet at Transducer Room, the heat that produces when frequency converter is moved directly is extracted into outdoor, improve the frequency converter operational environment, improved the frequency converter reliability of operation; Reduce air-conditioner operation time, reduced cost.
Description of drawings
Fig. 1 is the schematic diagram of Transducer Room aeration structure of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model provides a kind of Transducer Room aeration structure, wherein: wind gathering cover 2 is installed above fan of frequency converter 1; Be provided with air inlet 4 in Transducer Room 3 one side walls bottoms, increase wind flow; Be provided with air outlet 5 on 3 pairs of side walls tops of Transducer Room, this air outlet 5 is provided with axial flow blower 6 and links to each other with wind gathering cover 2 by air channel 7, and the heat that frequency converter 8 is produced is as far as possible directly discharged outside the Transducer Room 3.
The utility model is by setting up axial flow blower 6, wind gathering cover 2, air channel 7, air inlet 4 and air outlet 5 at Transducer Room 3, the heat that produces during with frequency converter 8 operation directly is extracted into outdoor, has improved the frequency converter operational environment, has improved the frequency converter reliability of operation; Reduce air-conditioner operation time, reduced cost, had energy-saving effect.
For the air of guaranteeing to enter Transducer Room 3 is clean, air inlet 4 can be provided with filter screen, and uses for convenient, can also set up outer cover plate.Air inlet 4 can be 20-30cm apart from the height on ground, is preferably 25cm.
Air outlet 5 can be equipped with outer closure plate, can prevent that outdoor dust from entering Transducer Room 3 like this when axial flow blower 6 is stopped transport.Air outlet 5 can be 25-35cm apart from the height at Transducer Room top, is preferably 30cm.
The diameter of axial flow blower 6 is preferably 660mm.Wind gathering cover 2 is 30-40cm apart from the height of frequency converter 8, is preferably 35cm, and frequency converter 8 still can work during with 6 maintenance of assurance axial flow blower.
To sum up, the utlity model has following advantage:
(1) the utility model is by setting up axial flow blower, wind gathering cover, air channel, air inlet and air outlet at Transducer Room, and the heat that produces when frequency converter is moved directly is extracted into outdoor, has improved the frequency converter operational environment, has improved the frequency converter reliability of operation.
(2) can greatly alleviate the dependence to air-conditioning summer; When winter, outdoor temperature was low, the air-conditioning of can stopping transport relied on Transducer Room aeration structure of the present utility model can guarantee the frequency converter normal operation, greatly reduces the power consumption of air-conditioning.
The above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model; If do not break away from spirit and scope of the present utility model, the utility model is made amendment or is equal to replacement, all should be encompassed in the middle of the protection range of the utility model claim.
