Abstract
The invention belongs to the structural design field of moisture absorbers for transformers, and particularly relates to a detachment-free moisture absorber for a power transformer, which does not need to be detached during replacement of both silica gel and insulating oil, so that the operation of on-site maintenance personnel is facilitated. The detachment-free moisture absorber adopts the structure that a connecting flange is connected with a tank body through an upper sealing head, and the bottom of the tank body is connected with an oil cup through a lower sealing head; a silica gel inlet is formed on the upper sealing head, and a silica gel outlet is formed on the lower sealing head; an inclined screen is arranged at the inner bottom of the tank body; an oil cup protecting screen is connected to the outer bottom of the tank body; the oil cup is arranged in the oil cup protecting screen; and an oil cup outlet is connected to the bottom of the oil cup protecting screen. The detachment-free moisture absorber facilitates replacing both the silica gel and the insulating oil, is not only safe but also labor-saving, greatly reduces the workload of operating personnel, remarkably improves the working efficiency, has the obvious characteristics of simple and reasonable structure and apparent effects, and is favorable for wide popularization and application.
Description
Technical field
The invention belongs to transformer with dehydrating breather structural design field, relate in particular to a kind of power transformer with exempting from dismounting type dehydrating breather.This dehydrating breather is when changing silica gel and insulating oil, and need not to dismantle dehydrating breather can accomplish, and makes things convenient for on-site maintenance personnel's operation.
Background technology
As shown in Figure 1, Fig. 1 is the dehydrating breather of conventional structure in the prior art.Adopt this structure dehydrating breather, the attendant needs two people can accomplish from the transformer dismounting when changing silica gel, and a human hand rest is lived dehydrating breather, and an other people turns on adpting flange 1, causes dehydrating breather to damage in the operating process easily, wastes time and energy simultaneously.When the attendant when changing insulating oil, need a people hold lubricating cup 6 earlier equally, prevent lubricating cup 6 damage that comes off; An other people turns on fixed screw 5, so very easily causes lubricating cup in unloading process, to cause damage, wastes time and energy simultaneously, brings very big inconvenience to work of maintenance personnel.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of power transformer with exempting from dismounting type dehydrating breather, its objective is the solution dehydrating breather replacing silica gel in the past and the problem of insulating oil difficulty.
The present invention realizes through following technical scheme:
Power transformer comprises that with exempting from dismounting type dehydrating breather adpting flange is connected with tank body through upper cover, and tank base is connected with lubricating cup through bottom head; Upper cover is provided with the silica gel inlet, and bottom head is provided with the silica gel outlet; The tank body inner bottom part is provided with oblique net, and the lubricating cup protecting wire net is connected on the outer bottom of tank body, and lubricating cup is located in the lubricating cup protecting wire net, and the lubricating cup outlet is connected the bottom of lubricating cup protecting wire net.
The top of said lubricating cup protecting wire net is provided with the top protection pad, and the bottom of lubricating cup protecting wire net is provided with the bottom protection pad.
Advantage and beneficial effect: the present invention needn't dismantle dehydrating breather when replacing silica gel, only need open the silica gel outlet and discharge silica gel, opens silica gel inlet interpolation silica gel and gets final product; When changing insulating oil, only need turn on the lubricating cup outlet and can take out lubricating cup.The present invention can change silica gel and insulating oil easily, and is not only safe but also laborsaving, reduced operating personnel's workload widely, makes operating efficiency obtain significant raising.It is simple for structure reasonable also to have, and the outstanding effect distinguishing feature is beneficial to extensive promotion and application.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed explanation.
Fig. 1 is the structural representation of the conventional dehydrating breather of prior art;
Fig. 2 is a structural representation of the present invention.
Among the figure: adpting flange 1, upper cover 2, tank body 3, bottom head 4, fixed screw 5, lubricating cup 6 tiltedly nets 7, top protection pad 8, lubricating cup protecting wire net 9, bottom protection pad 10, lubricating cup outlet 11, silica gel inlet 12, silica gel outlet 13.
Embodiment
The present invention be a kind of power transformer with exempting from dismounting type dehydrating breather, be that existing dehydrating breather is improved.As shown in Figure 2, Fig. 2 is a structural representation of the present invention.Comprise that adpting flange 1 is connected with tank body 3 through upper cover 2; Tank body 3 bottoms are connected with lubricating cup 6 through bottom head 4; On the basis of these existing dehydrating breathers, the present invention increases on upper cover 2 and is provided with silica gel inlet 12, on the bottom head 4 of tank body 3, has increased silica gel outlet 13.Tank body 3 inner bottom part increases are provided with oblique net 7, when replacing silica gel, only need open silica gel outlet 13 and discharge silica gel, open silica gel inlet 12 interpolation silica gel and get final product.
Lubricating cup 6 be not installed on the fixed screw 5 in the present invention; But lubricating cup 6 is located in the lubricating cup protecting wire net 9; The top of said lubricating cup protecting wire net 9 is provided with top protection pad 8, and the bottom of lubricating cup protecting wire net 9 is provided with bottom protection pad 10, and this top protection pad 8 is used for fixing lubricating cup 6 with bottom protection pad 10; Prevent lubricating cup 6 shakes, lubricating cup outlet 11 is connected the bottom of lubricating cup protecting wire net 9 through helicitic texture.Whole lubricating cup protecting wire net 9 is fixed on the tank body 3 through fixed screw 5.The present invention only need turn on lubricating cup outlet 11 when changing insulating oil, can take out lubricating cup 6 and carry out the replacing of insulating oil, and operation is very easy.
