In conjunction with shown in Fig. 1 to Fig. 3, a kind of 10kV distribution transformer provided by the utility model is ice-covering-proof, antifouling work device,
Including conducting rod 1, which can be made of the good copper material of electric conductivity, and the bottom of conducting rod 1 is equipped with and transformation
The screw hole 4 that first screw rod at 7 top of device casing matches, the top of conducting rod 1 are equipped with the second screw rod 5, and the second screw rod 5 is equipped with
Two nuts 6；The outer cover of conducting rod 1 is equipped with epoxy resin layer 2, and the outer cover of epoxy resin layer 2 is equipped with several silicon rubber umbrellas
Skirt 3.
When decreasing insulating occurs in bushing shell for transformer 7, there are when short-circuit risks, remove 7 top of bushing shell for transformer first
Two nuts 6 on first screw rod, while the lead-out wire of transformer being removed from bushing shell for transformer 7；It then will be originally practical new
The first screw rod of bottom alignment of the conducting rod 1 of type embodiment screws in the first screw rod in screw hole 4, is thus fixed on the present apparatus
On bushing shell for transformer 7, two nuts 6 can be finally mounted on the second screw rod 5, while the connector sleeve of lead-out wire being set in
On second screw rod 5 and it is folded between two nuts 6.
After installing the present apparatus additional, it is equivalent to the height for having increased insulating sleeve, creepage distance is increased, thus solves and cover
The problem that ice season casing ground connection, short circuit accident take place frequently.In addition, the conducting rod 1 of the present apparatus passes through the screw hole 4 and transformer of bottom
7 top the first screw flight cooperation of casing realizes the installation of the present apparatus, utilizes the intrinsic shape at 7 top of bushing shell for transformer
Shape is installed easy to operate；Also, since the diameter of the second screw rod 5 is identical as the first screw rod, using two disassembled
A nut 6 cooperates the second screw rod 5 to realize the installation of lead-out wire, and structure is simple, easy to operate；Also, the present apparatus passes through asphalt mixtures modified by epoxy resin
Rouge layer 2 and silicon rubber umbrella skirt 3 realize the insulation of conducting rod 1, greatly alleviate the weight of the present apparatus, save installation operation more
Power.Finally, existing transformer high-voltage bushing ground connection, short-circuit risks are solved the problems, such as by the present apparatus, compared to it is traditional more
The mode of the bushing of higher voltage grade is changed, operation is simpler, laborsaving, and distribution transformer high pressure can be effectively prevented
The generation of ground connection, short circuit accident at casing.
In some embodiments, gasket is equipped on the second screw rod 5 and between two nuts 6, gasket can increase
The stability that nut 6 connects, prevents nut 6 from loosening.
In some embodiments, conducting rod 1 is prismatic, preferably regular hexagonal prism shape, due to during the installation process, needing
Rotate conducting rod 1, therefore, if conducting rod 1 is cylinder, outside the epoxy resin layer 2 that is arranged be easy to occur it is circumferential sliding
Dynamic, there are big inconvenience benefits when rotational installation.After the present apparatus sets prismatic for conducting rod 1, this dress can be installed
During setting, it effectively prevent between epoxy resin layer 2 and conducting rod 1 that there is a phenomenon where skid.
Further, the top of partially electronically conductive bar 1 is in epoxy resin layer 2 by exposing, and thus one, it can use hexagonal and pull
The exposing conducting rod 1 of the tools such as hand and the part, which is formed, to be cooperated, and screws conducting rod 1 by tools such as spanners, make more convenient operation,
It is laborsaving.
Purpose due to installing the present apparatus additional is to increase creepage distance, and so as to improve dielectric level, and conducting rod 1 is outer due to set
Equipped with epoxy resin layer 2 and silicon rubber umbrella skirt 3, so the body part of the present apparatus can guarantee good insulating properties, therefore, In
The junction of the present apparatus and bushing shell for transformer 7 becomes as the key area of a sealed insulation, if where there is leakages, then
It installs the present apparatus additional and just loses the effect for improving creepage distance.
In some embodiments, the bottom of silicon rubber umbrella skirt 3 is equipped with is adapted with the insulator top shape of bushing shell for transformer 7
Recess, conducting rod 1 after the installation is completed, the recess of full skirt bottom can the more strict insulator main header casing by bushing shell for transformer 7
Firmly, it thus prevents conducting rod 1 exposed, effectively raises safety, prevent the generation of conducting rod 1 ground connection, short-circuit conditions.
In further embodiments, the bottom of silicon rubber umbrella skirt 3 is equipped with recess, and the bore of recess from the inside to the outside gradually increases
Greatly, the biggish opening of recess can easier set be set on the top of bushing shell for transformer 7；Wherein, it is also wrapped in the side wall of recess
Equipped with multiple muscle bars 8, multiple circumferentially-spaced distributions of muscle, each muscle bar 8 is along the axially extending of silicon rubber umbrella skirt 3.Becoming as a result,
When the top of depressor casing 7 is gradually inserted in recess, the top of bushing shell for transformer 7 can open outward the top of each muscle bar 8,
According to lever principle, the bottom end of each muscle bar 8 can inwardly be swung, and thus make the opening portion of recess to contract, thus closely
It is coated on the insulator top of bushing shell for transformer 7, forms more strict sealing.
Further, muscle bar 8 is the arc of outwardly convex, the muscle bar 8 of the arc not only top shape with bushing shell for transformer 7
It more adapts to, and after recess contraction, the oral area of recess can also be made to seal tighter.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
