The utility model discloses not only can improve antirust effect, guarantee long -term reliable use, the quality is light moreover, easily overhauls, can accelerate rain drops landing speed simultaneously, and the abominable corrosion environment of difficult formation improves the resistant to rust ability, still can make field distribution even, uses more reliably in the transformer substation.
Description
Technical field
The utility model relates to power industry power transformation technical field of auxiliary equipment, particularly a kind of instrument transformer rain cover.
Background technology
Instrument transformer is also called instrument transformer; it is the general designation of current transformer and voltage transformer; high voltage or big current scaling transformation are mainly become normal low voltage or standard low current by its function, to realize standardization, the miniaturization of measuring instrument, proterctive equipment and automatic control equipment.Because most instrument transformer is outdoor use, this just makes the rainproof measure of instrument transformer particularly important.
At present, normally install rain cover additional in instrument transformer outside rainproof to realize, in prior art, instrument transformer rain cover mainly contains following several:
The first is that rain cover adopts plastic production, and is cylindric, and have certain rainproof effect, but its shortcoming is, plastic products are easily aging under the Special use environment of transformer station, and useful life is low, poor reliability;
The second is rain cover is that one end is closed, the tubular structure of open at one end, and this rain cover adopts fiberglass to make, although its insulation property are better and cost of manufacture is lower, but the top due to this rain cover is plane, rainwater is easily made to accumulate at top, form severe operational environment, and the rainproof effect of this rain cover open end is poor, the rainproof effect that impact is overall;
The third is that rain cover adopts cast iron materials to make, and at its outer surface rust preventive coating, but its weak point is, in use procedure, under the alternating electric field of transformer station, rust preventive coating easily takes off, and this material as easy-to-rust of cast iron materials, make its rust resistance poorer, useful life is low, and the top of this rain cover structure is also adopt smooth design simultaneously, rainwater easily accumulates, worsen the operational environment of rain cover, and more easy-to-rust, further shorten useful life.
Therefore, need to improve existing instrument transformer rain cover, make it improve rust-proof effect, ensure to use reliably and with long-term, and quality is light, be easy to maintenance, raindrop slip velocity can be accelerated simultaneously, not easily form severe corrosion environment, improve resistant to rust ability, Electric Field Distribution also can be made even, use more reliable in transformer station.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of instrument transformer rain cover, can not only rust-proof effect be improved, ensure to use reliably and with long-term, and quality be light, be easy to maintenance, raindrop slip velocity can be accelerated simultaneously, not easily form severe corrosion environment, improve resistant to rust ability, Electric Field Distribution also can be made even, use more reliable in transformer station.
Instrument transformer rain cover of the present utility model, comprise rain cover body, described rain cover body is adopt aluminum to make the hemispherical dome structure that Open Side Down, the mouth end of this rain cover body has the annular extension vertically extended downwards, the wall of described annular extension is circumferentially interval with multiple installing hole for being connected and fixed with instrument transformer.
Further, buffer protection pad is provided with in described rain cover body.
Further, described buffer protection pad is hemispherical dome structure, and this buffer protection pad is fixedly connected on the inwall of rain cover body.
Further, the radius of described rain cover body is 20cm, and the development length of described annular extension is 2cm.
Further, described installing hole is four, and four installing holes are circumferentially distributed on the wall of annular extension.
The beneficial effects of the utility model: instrument transformer rain cover of the present utility model, rain cover body adopts aluminum integral production shaping, the advantage that the ductility of aluminum own is good can not only be utilized, be convenient to processing, and the oxide-film of one deck densification can be formed at the outer surface of rain cover body, protection internal structure is from corrosion, and corrosion-resistant property is good, and the quality of aluminium is light, conveniently rain cover body is overhauled; Rain cover body adopts hemispherical dome structure simultaneously, make rainwater slide fast, short in the time that rain cover body outer surface stops, avoid ponding, severe corrosion environment can not be formed, and due to hemispherical dome structure curvature little, Electric Field Distribution is even, also not easily point discharge is there is, not entail dangers to device security under the alternating electric field of transformer station; Also can utilize the electric conductivity of aluminum itself, enable rain cover body ground connection, use more safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Embodiment
Fig. 1 is structural representation of the present utility model, Fig. 2 is the cutaway view of Fig. 1, Fig. 3 is the vertical view of Fig. 1, as shown in the figure: the instrument transformer rain cover of the present embodiment, comprise rain cover body 1, described rain cover body 1 is adopt aluminum to make the hemispherical dome structure that Open Side Down, the mouth end of this rain cover body 1 has the annular extension 2 vertically extended downwards, the wall of described annular extension 2 is circumferentially interval with multiple installing hole 3 for being connected and fixed with instrument transformer, during use, only rain cover body 1 need be covered on instrument transformer top, and by bolt through installing hole 3, can rain cover body 1 be fixed on instrument transformer, play rainproof effect, because rain cover body 1 adopts aluminum integral production shaping, the advantage that the ductility of aluminum own is good can not only be utilized, be convenient to processing, and the oxide-film of one deck densification can be formed at the outer surface of rain cover body 1, protection internal structure is from corrosion, corrosion-resistant property is good, and the quality of aluminium is light, conveniently rain cover body 1 is overhauled, rain cover body 1 adopts hemispherical dome structure simultaneously, make rainwater slide fast, short in the time that rain cover body 1 outer surface stops, avoid ponding, severe corrosion environment can not be formed, and due to hemispherical dome structure curvature little, Electric Field Distribution is even, also not easily point discharge is there is, not entail dangers to device security under the alternating electric field of transformer station, also can utilize the electric conductivity of aluminum itself, make rain cover body 1 can ground connection, use more safe and reliable.
