Abstract
The invention relates to an electrical engineering appliance, in particular to a moisture absorber used for a transformer and a mutual inductor, wherein the moisture absorber comprises a shell; two completely same purification chambers which are connected in parallel are arranged in the shell; a humidity sensor is arranged in each purification chamber; the purification chamber is completely partitioned by adopting a partition plate directly; automatic valves are arranged on the top and the bottom of each purification chamber; and an exhaust hole is also formed on the top of each purification chamber. After the design is adopted, when one purification chamber is maintained, the purification chamber can be switched to the other purification chamber to keep normal operation, so that the normal operation of the moisture absorber cannot be influenced during dehumidification, and more installation space is saved compared with that of the design with two moisture absorbers.
Description
Technical field
The present invention relates to a kind of power engineering apparatus, be specifically related to the dehydrating breather that a kind of transformer and instrument transformer are used.
Background technology
Power transformer generally passes through capsule or wavy metal by transformer oil and air insulated, to avoid transformer to make moist.The impurity such as airborne moisture can have a negative impact to the life-span of capsule or wavy metal, once capsule or wavy metal are damaged, transformer oil will make moist, thereby affects transformer life.In order to improve the useful life of capsule or wavy metal, reduce the danger that transformer makes moist, the general pneumostome at capsule or wavy metal connects dehydrating breather and removes the impurity such as airborne moisture.
Along with the progress of transformer technology, the intelligent requirement of controlling is day by day strong.Some structures, the annex of tradition dehydrating breather is unfavorable for intelligent control, just progressively eliminates, and transformer technology, annex are to intellectuality non-maintaining aspect development.Tradition dehydrating breather needs manual maintenance to be unfavorable for realizing intelligent.The current domestic weight sensor of taking, also has and takes humidity sensor as recognition system; What the dehydrating breather of external some enterprise was taked is humidity sensor, utilizes water vapour chance wall cooling from bottom discharge; The dehydrating breather scheme also having has adopted two dehydrating breathers, during one of them dehumidifying, can be switched to another dehydrating breather work, but above-mentioned technology is all difficult to perfection, reaches reduction annex volume, improves the intelligent object of controlling.
Summary of the invention
The many weak points that exist for prior art, the invention provides the dehydrating breather that a kind of transformer and instrument transformer are used, this dehydrating breather comprises housing, in housing, be provided with two identical clean rooms in parallel, in each clean room, be provided with humidity sensor, and clean room directly adopts dividing plate to isolate completely, top, clean room and bottom are provided with automatic valve, top, clean room is also provided with steam vent, adopt after this design, when Dang Yige safeguards clean room, can be switched to another clean room and keep normal work, in the time of can either meeting dehumidifying, not affecting dehydrating breather normally works, again than using two dehydrating breathers to save installing space.
Concrete technical scheme of the present invention is: a kind of dehydrating breather, comprise housing, in housing, be provided with two identical clean rooms in parallel, in each clean room, be provided with humidity sensor, and clean room directly adopts dividing plate to isolate completely, top, clean room and bottom are provided with automatic valve, and top, clean room is also provided with steam vent, are provided with heater in clean room.
Adopt after this design, when Dang Yige safeguards clean room, can be switched to another clean room and keep normal work, in the time of can either meeting dehumidifying, do not affect dehydrating breather and normally work, again than using two dehydrating breathers to save installing space.Detailed process is: whether first utilize humidity sensor in clean room to identify needs dehumidifying in this clean room, if need dehumidifying in this clean room, the automatic valve arranging by top, clean room and bottom, Jiang Gai closes clean room the steam vent of simultaneously opening in this clean room, operating state can be switched to another clean room; Then start the heater heating and dehumidification in this clean room, and utilize the low rising principle of hot water and steam density to discharge water vapour from working chamber top steam vent; Finally by humidity sensor, judge whether to dehumidify complete, dehumidify and completely close steam vent and automatic valve Shi Gai clean room is standby.
On dehydrating breather housing, be provided with control cabinet, housing bottom is connected with filter chamber, and top is connected with ring flange, can facilitate being like this connected of dehydrating breather and other equipment.
In sum, adopt after the dehydrating breather of this structure, when Dang Yige safeguards clean room, can be switched to another clean room and keep normal work, in the time of can either meeting dehumidifying, not affecting dehydrating breather normally works, again than using two dehydrating breathers to save installing space, having realized Based Intelligent Control, is the full intellectualized advantage that provides of whole transformer or instrument transformer.
