Description
Technical field
The utility model belongs to transformer auxiliary equipment, is specifically related to a kind of transformer maintenance-free moisture absorber.
Background technology
Dehydrating breather is a kind of air dewetting of using for oil-filled transformer, instrument transformer, on load tap changer or other electric equipment being filled with dielectric and purifier.It is arranged on the air inlet of transformer or instrument transformer oil conservator, when transformer or instrument transformer make oil volume generation harmomegathus in running due to oil temperature change, force the gas in oil conservator to be produced by dehydrating breather to breathe, air enters transformer by the drier in dehydrating breather, can ensure that the gas sucked is dry, to keep the clean of transformer oil and dielectric strength.
Traditional dehydrating breather long-time time after drier can make moist, cause drying capacity to reduce, even if spare no effort to safeguard to ensure safety, therefore maintenance cost also can increase.Existing maintenance-free moisture absorber heats drier by being provided with heater in hothouse inside, due to heater many uses heating plate and heater strip, can not reach the effect of even dry all drier.
Utility model content
The purpose of this utility model is to provide a kind of dehydrating breather of homogeneous heating.
The utility model solves the technical scheme that its technical problem adopts: a kind of transformer maintenance-free moisture absorber, comprise by upper end cover, the housing that bottom end cover and guard shield are formed and the steel wire guard be placed in housing, temperature sensor and drier is provided with in steel wire guard, air-tight cabin is provided with above upper end cover, electromagnetically operated valve is provided with in air-tight cabin, air-tight cabin is provided with flange, one or more heating core is provided with in described guard shield, described heating core is by the heating rod being positioned at guard shield axle center, the multiple heating plate compositions being fixed on the heating core inner bag outside heating rod and extending along heating core inner bag radial direction.
Described a kind of transformer maintenance-free moisture absorber, its multiple heating core removably connects, and top side heating core is connected on upper end cover by heating core link plate.
Described a kind of transformer maintenance-free moisture absorber, is provided with fan in its bottom end cover.
Described a kind of transformer maintenance-free moisture absorber, is filled with heat conductive silica gel between its heating rod and heating core inner bag.
Described a kind of transformer maintenance-free moisture absorber, is characterized in that, described guard shield is translucent cover.
The beneficial effects of the utility model are: heating core by be positioned at guard shield axle center heating rod, be fixed on heating core inner bag outside heating rod and form along multiple heating plates that heating core inner bag radial direction extends, drier in such steel wire guard is between adjacent two heating plates, drier is evenly distributed in steel wire guard can thermally equivalent, in addition heating core can select as required fill one or more, thus meet the use needs of different size transformer, significantly reduce maintenance cost.
