Description
Technical field
The utility model is related to a kind of high voltage converter air water cooling for controlling high voltage converter running temperature but device,
Belong to cooling technology field.
Background technology
Power electronic power device in frequency converter can be generated heat in normal course of operation, and these heats are dissipated in cabinet
Portion so that temperature is raised in frequency converter.And no more than 85 DEG C of case temperature during power electronic power device normal work, such as
Fruit temperature is too high, and frequency converter will automatic trip.Therefore certain cooling provision must be taken, by the cabinet of high voltage converter equipment
Body temperature is controlled below 65 DEG C, to ensure frequency conversion equipment stable operation.
At present, typically using air water cooling, but device is cooled down high voltage converter, and its operation principle is, the heat in frequency converter
Wind by cabinet top fan extract out after the air/water cooler and the cooling water that are entered by air channel outside Transducer Room exchange heat, the cold wind after cooling
Flow back in Transducer Room, by temperature control in Transducer Room below 40 DEG C.This cooling device only controls environment temperature, and does not have
There is the influence for considering humidity to frequency converter running environment, table 1 gives the air dew point temperature under different relative humidity：
Air dew point temperature under the different relative humidity of table 1（℃）
It can be seen from Table 1 that, the relative humidity of air is higher, and dew point is just closer to environment temperature, when room temperature is controlled not
When can meet dewpoint requirements, the cold wind exit in air channel is easily condensed, and condensed water is blown on transducer body, will give high pressure
Frequency converter brings great potential safety hazard.
In addition, being usually one or more cabinet top fan one sky of correspondence in the cooling system of conventional high-tension frequency converter
Water cooler, irredundant design, and when cabinet top fan breaks down, hot blast can not be discharged in time, frequency converter temperature will be anxious
Play rise, easily causes frequency converter overtemperature to trip.
Utility model content
There is provided a kind of improved high voltage converter air water cooling for the drawback that the purpose of this utility model is for prior art
But device, while frequency converter indoor temperature is reduced, it is to avoid influence of the condensation to high voltage converter.
Problem described in the utility model is realized with following technical proposals：
A kind of high voltage converter air water cooling but device, composition includes humiture instrument, air/water cooler and temperature adjustment
Valve, the humiture instrument is arranged on inside Transducer Room；The air/water cooler is arranged on outside Transducer Room, and air water cooling is but
The blast pipe of device is connected after passing through Transducer Room wall with the air outlet of the cabinet top fan of high voltage converter, and backwind tube stretches into frequency conversion
In device room；The temperature control valve (TCV) is connected on the cooling water pipe of air/water cooler, the control termination humiture instrument of temperature control valve (TCV)
The temperature signal output end of table.
Above-mentioned high voltage converter air water cooling but device, the end of the backwind tube of the air/water cooler is provided with mist eliminator, institute
The drainpipe for stating mist eliminator is provided with showering guilding valve.
Booster fan is provided with above-mentioned high voltage converter air water cooling but device, the backwind tube of the air/water cooler.
Above-mentioned high voltage converter air water cooling but device, the cooling water pipe of the air/water cooler is provided with hand stop valve.
Temperature control valve (TCV) of the present utility model can adjust empty water according to the frequency converter indoor temperature of humiture instrument measurement
The quantity of circulating water of cooler, and the control parameter of humiture instrument can be adjusted according to the change of season and humidity, thus
Avoid because Transducer Room temperature is low, high humidity and caused by condensation, it is ensured that the safe operation of high voltage converter.
The effect of mist eliminator is trapping because the response speed of temperature control valve (TCV) is slowly and in the cold of Transducer Room cold wind mouthful condensation
Solidifying water, prevents condensed water from being had undesirable effect to frequency conversion equipment；Booster fan not only can effectively solve air/water cooler backwind tube
The problem of blast and low wind speed, can also avoid because cabinet top fan failure and caused by trip accident, improve air water cooling but device
Operational reliability.
