Description
Technical field
The utility model is related to moisture absorber device, more particularly to a kind of intelligent dehydrating breather.
Background technology
Dehydrating breather, is to utilize automatic heating, drying principle, the air designed for oil-filled transformer also known as " respirator "
Automatic purification device.Dehydrating breather is arranged on oil storage tank of oil immersed transformer, when change of the transformer due to load or environment temperature
Change and the volume of transformer oil is occurred breathing, force metal filter screen and drier of the gas in oil conservater by dehydrating breather
When being breathed, the debris and moisture in the air of entrance are removed, so as to maintain the dielectric strength of transformer oil.When long
Between after use, drier makes moist when reaching default rh value, and intelligent dehydrating breather is automatically starting heat drying work(
Can, the moisture in drier is automatically removed, recovers drier wettability power, so moves in circles and use, so as to reach breathing
The non-maintaining purpose of device.
Existing intelligent dehydrating breather surveys gas rh value and temperature value using temperature and relative humidity, with change
Depressor is breathed for a long time, and the drier moisture absorption causes gas relative humidity constantly to rise, when actual measurement rh value exceedes setting threshold
After value, delay confirmation is carried out silica-gel desiccant drying restoring operation for a period of time.When equipment carries out baking and banking up with earth dry, temperature is big
When set protection value, MUC computer terminals send instruction cut-out hothouse power supply, after automatic recovery heating after temperature reduction.
Temperature protection monitoring function, which is realized, to be realized by the temperature measurement function of temperature and relative humidity, is indirect measurement gas temperature
Spend to protect itself temperature and relative humidity and prevent the too high function of causing silica gel to fail of silica gel heating reduction temperature；But deposit
In two shortcomings：If first temperature and relative humidity failure, can not just realize the function, but device can still be run；Second
Measurement gas temperature, easily influenced by ambient temperature indirectly, it is difficult to true reflection silica gel heating reduction temperature, can so cause silica gel
Heating-up temperature difficulty or ease are controlled, so as to cause heating reduction temperature to exceed the silica gel reduction temperature value limit.
The content of the invention
The purpose of this utility model is in order to which solve the above problems being capable of direct measurement drier heating-up temperature there is provided one kind
Value, improves the intelligent dehydrating breather of drier service life.
Therefore, the technical solution of the utility model is：Above a kind of intelligent dehydrating breather, including cylindrical shell, housing
Provided with upper end cover, upper end cover, which is fixed with below adpting flange, housing, is provided with bottom end cover, provided with ventilative grid at bottom end cover, grid of breathing freely
On temperature control heating filter is installed；The housing side is provided with control cabinet, and housing is provided with Temperature Humidity Sensor, and humiture is passed
Sensor is connected with the temperature control heating filter of housing lower end with control cabinet；It is characterized in that：Drying is provided with the housing
Heat and some desiccant heaters are installed on plate rack provided with heating plate rack in agent, drier side；The heating plate rack
On be further fixed on the first temperature sensor, the first temperature sensor is in contact with desiccant heater；First TEMP
Device is connected with control cabinet.
Further, the heating plate rack is up to provided with 12 desiccant heaters less.
Existing dehydrating breather operation principle：After the self-inspection that switches on power terminates, equipment enters use pattern, Temperature Humidity Sensor
Gas rh value and temperature value are surveyed, as transformer is breathed for a long time, bucket internal desiccant（Silica gel）The moisture absorption causes gas
Relative humidity constantly rises, after rh value is surveyed more than given threshold, and delay confirmation is carried out silica gel and done for a period of time
Drying prescription dries restoring operation.
It is normal that Temperature Humidity Sensor damages protection equipment function：After equipment heating, drying terminates, if Oil Tank chamber air
Breathe no more flowing, if rh value is not below default humidity value, MUC recognizes that prevention sends heating, drying and referred to by comparing
Order, with reference to timing controller, decontrols detection, delay is determined, just starts heating, drying during control time half.If rh value
Less than predetermined threshold value, then drying heating is not started.Gas relative humidity measured value is caused always to be less than if Temperature Humidity Sensor is damaged
Lower limit judgment value, then control time one arrive, delayed startup heating, drying.
When equipment carries out baking and banking up with earth dry, when temperature is more than set protection value, MUC sends instruction cut-out hothouse electricity
Source, after automatic recovery heating after temperature reduction.The realization of temperature protection monitoring function is the temperature survey by Temperature Humidity Sensor
What function was realized, it is indirect measurement gas temperature to protect itself temperature and relative humidity and prevent silica gel heating reduction temperature mistake
Height causes the function that silica gel fails.
And the utility model adds the first independent all the way temperature sensor on the basis of existing technology, than original dress
One-level overheat protector function is put many；First temperature sensor is directly installed in housing, with silica gel（Drier）Heater is straight
Contact, its heating-up temperature value of direct measurement is not influenced by ambient temperature；The temperature survey of original Temperature Humidity Sensor is made simultaneously
Continue to retain for indirect protection function；On this basis, silica gel is increased（Drier）The quantity of heater, improves heating reduction effect
Rate, and have the first temperature sensor direct measurement silica gel（Drier）Reduction temperature, it is possible to realize and directly control silica gel（It is dry
Drying prescription）Heating-up temperature, so as to improve silica gel（Drier）Service life.
