Abstract
The utility model relates to an integrated silicone oil solidification full-dry type wall bushing with a current transformer, which comprises an insulated belt, a fixed flange, a uniform pressure cover and a positioning ring. A nameplate is arranged on the fixed flange; the uniform pressure cover is pressed on the positioning ring; the insulated belt consists of solidification silicone oil and an orientation film; and the solidification silicone oil is positioned between any two adjacent layers of the orientation film. In addition, the insulated belt comprises more than one silicon rubber umbrella skirt. In the utility model, as the solidification silicone oil technology is adopted, electrical accidents due to leakage of the silicone oil can be effectively prevented, thereby effectively ensuring the safe operation of an electric power system.
Description
Technical field
The utility model relates to a kind of wall bushing, is specially a kind of belt current instrument transformer integral type silicon oil solidifying full dry type wall bushing.
Background technology
The dry type mutual inductor of combined type insulation is a kind of new transformer of just putting on market over past ten years; It is compared with traditional oil immersed type instrument transformer; Because advantages such as having and do not have oil, no gas, no porcelain, volume is little, in light weight, the anti-explosion fire ability is strong, just put on market and developed rapidly.But because a kind of organic combined insulated band that the insulating tape of the outer wall bushing of instrument transformer is made up of liquid silicone oil and oriented film after operation in a few years, the phenomenon of liquid silicon oil seepage can occur.At present, the skin of insulating tape all is the method that adopts the heat-shrink tube sealing.Wall bushing some for a long time in outdoor operation; Because hot, electric, cold, ultraviolet, effect of factors such as be exposed to the sun, after the use certain hour, the outer field heat-shrink tube of insulating tape (particularly interface, sealing part) is understood aging phenomena such as appearance corrosion; Adding the liquid silicone oil that is sealed in the heat-shrink tube itself is exactly the goodish liquid of a kind of flowability; When product temperature raise, it can expand, and in heat-shrink tube, produced a kind of external pressure; In case when the outer field heat-shrink tube of insulating tape weak link occurred because of wearing out, liquid silicone oil just might break through outer heat-shrink tube and exosmose.In case liquid silicon oil seepage; Not only influence its surrounding enviroment, mainly reduce the dielectric strength of high-voltage electrical equipment, running time one is long; Leakage reaches some; Product is put increase because of office, may cause that product is breakdown, mis-behave even cause accidents such as other electric equipment products blast, has a strong impact on safe operation of power system.For a long time, the problem at interface, sealing part seepage silicone oil is never solved at all.
The utility model content
The technical problem that the utility model solved is to provide a kind of belt current instrument transformer integral type silicon oil solidifying full dry type wall bushing, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
Belt current instrument transformer integral type silicon oil solidifying full dry type wall bushing; Comprise insulating tape, mounting flange, grading shield and locating ring, on the said mounting flange nameplate be housed, said grading shield be pressed in said locating ring above; Said insulating tape is formed by solidifying silicone oil and oriented film; The solidification of silicon oil level is between every layer of oriented film, and said insulating tape comprises more than one silicon rubber full skirt.
The utility model is wooden packing, should prevent its damage during knocked-down packing and guarantee reliable ground before operation; During transportation, should prevent that it from receiving strenuous vibration and damaged surfaces; Should make the flange place stressed when lifting and carrying, can not make the High-Voltage Insulation part at the utility model two ends stressed, note protecting its surface and full skirt; After putting into operation, should carry out routine inspection to it according to the rules; Can use soft silk wiping during cleaning.
Beneficial effect
The utility model is used for rated frequency 50～60Hz, makes indoor, the outdoor connection usefulness of supports insulative and circuit in the alternating current circuit, is widely used in indoor substation, the lead wire insulation during power plant and large special transformer bus wall through walls.The utility model has adopted the silicon oil solidifying technology, and after silicon oil solidifying became the solidification of silicon oil film, dielectric constant was constant; No longer has flowability; Fundamentally solve the silicone oil leakage problems, become real dry type environment-friendly products, solve the pendent technical barrier of long-term puzzlement High-Voltage Electrical Appliances industry; Can prevent effectively that the electrical equipment accident that causes owing to the silicone oil seepage from taking place, thereby more effectively guarantee the safe operation of electric power system.
Description of drawings
Fig. 1 is the front view of belt current instrument transformer integral type silicon oil solidifying full dry type wall bushing band section.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1; The front view of belt current instrument transformer integral type silicon oil solidifying full dry type wall bushing band section, belt current instrument transformer integral type silicon oil solidifying full dry type wall bushing comprises insulating tape, mounting flange, outlet terminal, capacitor core, grading shield 3 and locating ring 2; On the said mounting flange nameplate is housed; Said grading shield 3 be pressed in said locating ring 2 above, said insulating tape is formed by solidifying silicone oil and oriented film, the solidification of silicon oil level is between every layer of oriented film; And said insulating tape comprises more than one silicon rubber full skirt 1.A winding in the utility model is a linear pattern, and external insulation adopts the silicon rubber full skirt to divide outdoor, indoor two ends, and its outdoor end creep distance ratio is 20,25,31mm/KV.
The utility model is wooden packing, should prevent its damage during knocked-down packing and guarantee reliable ground before operation; During transportation, should prevent that it from receiving strenuous vibration and damaged surfaces; Should make the flange place stressed when lifting and carrying, can not make the High-Voltage Insulation part at the utility model two ends stressed, note protecting its surface and full skirt; After putting into operation, should carry out routine inspection to it according to the rules; Can use soft silk wiping during cleaning.
All metal-wares that expose of the utility model should not have burr, wedge angle, cracking, and overcoat should be arranged.Earlier with sleeve surface and full skirt wiped clean and oven dry, sleeve pipe and full skirt are tight fit before sticking skirt, and the indoor is the equipotential end, and conducting rod is not play and rotation vertically under stressing conditions, when electric current is 1600 peace volts, without spacer ring 4, use the heat-shrink tube pyrocondensation.Mounting flange connects on the wall during installation, and end answers ground connection reliable, and famous brand is leaned on indoor end.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model; The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection range to be defined by appending claims and equivalent thereof.
