Description

For the double-cylinder type dehydrating breather of oil-filled transformer

Technical field

The utility model relates to oil-filled transformer field, more precisely a kind of for oil-filled transformerDouble-cylinder type dehydrating breather.

Background technology

Dehydrating breather in oil-filled transformer is a kind ofly to prevent that airborne moisture, dust from entering transformer oilA kind of device. But the screen pack in dehydrating breather is often blocked by dust; And interior can the placement of dehydrating breather can conventionallyThe hygroscopic agent of recycling, in the time that the abundant moisture of hygroscopic agent absorption lost efficacy, can be by reheatingDrier makes it have the ability of reuptaking moisture; But in dehydrating breather of the prior art, can only take outAfter hygroscopic agent, heat again, then insert new hygroscopic agent, the efficiency that this method is changed hygroscopic agent is lower, inhalesHumectant waste in the process of turnover is comparatively serious.

Utility model content

The utility model is mainly to solve the existing technical problem of prior art, thereby provides a kind of air-flow certainlyLower and upper through circular filter net, dust is not easy to be attached on screen pack; The lower end of urceolus is provided with removableThe end socket unloading, is convenient to clear up dust; On end socket, be provided with plug screw, can be by spiro pluging hole by shaft-like heatingDevice extend in inner core, thus heat drying agent, avoid take out and put into drier for oil immersed type transformationThe double-cylinder type dehydrating breather of device.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:

For a double-cylinder type dehydrating breather for oil-filled transformer, comprise that a urceolus, an air inlet pipe and give vent to angerPipe, the described double-cylinder type dehydrating breather for oil-filled transformer also comprise an inner core, a circular filter net andOne end socket, described inner core and described urceolus are coaxially arranged; The upper end of described urceolus and described inner coreFor hermetically-sealed construction; Urceolus described in described air inlet pipe penetrates is connected with the inner side of described inner core; DescribedEscape pipe be connected with the inner side of described urceolus; The outer ledge of described circular filter net and describedThe inwall of urceolus is connected, and the inside edge of described circular filter net is connected with the edge of described inner core;The lower end of described end socket and described urceolus forms dismountable syndeton; Described urceolus and describedBetween inner core, be placed with hygroscopic agent.

As the utility model preferred embodiment, the center of described end socket is provided with a plug screw; DescribedHygroscopic agent is the silica gel that is soaked with cobalt chloride.

The advantage of the double-cylinder type dehydrating breather for oil-filled transformer of the present utility model is: air-flow from bottom to topThrough circular filter net, dust is not easy to be attached on screen pack; The lower end of urceolus is provided with dismountable envelopeHead, is convenient to clear up dust; On end socket, be provided with plug screw, can shaft-like heater be stretched into by spiro pluging holeIn inner core, thereby heat drying agent avoids taking out and putting into drier.

Brief description of the drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below by rightIn embodiment or description of the Prior Art, the accompanying drawing of required use is briefly described, apparently, belowAccompanying drawing in description is only embodiment more of the present utility model, for those of ordinary skill in the art,Do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that the utility modelThereby advantage and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility modelMake more explicit defining.

As shown in Figure 1 and Figure 2, a kind of double-cylinder type dehydrating breather for oil-filled transformer, comprise a urceolus 1,One air inlet pipe 2 and an escape pipe 3, this double-cylinder type dehydrating breather that is used for oil-filled transformer also comprises an inner core4, a circular filter net 5 and an end socket 6, this inner core 4 is coaxially arranged with this urceolus 1; This urceolus 1 and shouldThe upper end of inner core 4 is hermetically-sealed construction; This air inlet pipe 2 penetrates this urceolus 1 and is connected with the inner side of this inner core 4;This escape pipe 3 is connected with the inner side of this urceolus 1; The outer ledge of this circular filter net 5 and this urceolus 1Inwall be connected, the inside edge of this circular filter net 5 is connected with the edge of this inner core 4; This end socket 6Form dismountable syndeton with the lower end of this urceolus 1; Between this urceolus 1 and this inner core 4, be placed with suctionHumectant. Air-flow is entered after this inner core 4 by air inlet pipe 2, flows from top to bottom, and dust is easily deposited on this envelopeIn 6; Air stream direction in the time of this circular filter net 5 is from bottom to top, and dust is not easy to be attached to thisIn circular filter net 5; Dismountable end socket 6 is convenient to user and is opened the dust stratification of this end socket 6 cleaning the insides.

The center of this end socket 6 is provided with a plug screw 7; This hygroscopic agent is the silica gel that is soaked with cobalt chloride. Open this spiral shellPlug 7, thus user can insert shaft-like electric heater in this inner core 4 and can heat hygroscopic agent, avoids turnoverHygroscopic agent; The silica gel that is soaked with cobalt chloride is a kind of common hygroscopic agent that can be multiplexing, after heat drying, both canRecover wettability power.

Below be only the mentality of designing of part embodiment of the present utility model, in the situation that system allows,The utility model can expand to external more functional module simultaneously, thereby expands to greatest extent its function.

The above be only detailed description of the invention of the present utility model, but protection domain of the present utility model alsoBe not limited to this, any variation of expecting without creative work or replacement, all should be encompassed in this practicality newWithin the protection domain of type. Therefore, protection domain of the present utility model should be so that claims were limitedProtection domain is as the criterion.
