Abstract
The utility model relates to a high voltage dry type wall bushing, which consists of a main insulation core, an outdoor terminal block, an outdoor porcelain shell, an assembled flange, a splice sleeve and an indoor porcelain shell. The utility model is characterized in that the main insulation core arranged in the outdoor porcelain shell and the indoor porcelain shell is an oil free sealed space which is formed by coiling a copper tube and organic membrane material wound around the copper tube and an aluminum foil according to the theory of capacitance voltage sharing.
Description
The utility model relates to a kind of high pressure dry wall bushing, belongs to high voltage substation support fitting class.
Use at present that the direct high pressure lead passes wall board for building, floor and roofing in power plant transformer station, as conduction current-carrying and high pressure over the ground wallboard insulation and support that this kind equipment of usefulness is the oil-paper high-voltage wall bushing.The main insulation fuse of this oil immersion paper mold wall bushing must be immersed in the transformer oil, in case transformer oil meets accident the insulation property of this equipment and safe in utilizationly promptly can be affected.Maintenance and testing amount in the daily use of this device is bigger in addition, and the oil plant that leaks also can pollute environment.
The purpose of the present utility model: aim to provide a kind of safe and reliable new construction high pressure dry wall bushing, not only reduce maintenance workload, also can reduce pollution.
This high pressure dry wall bushing is made up of main insulation fuse (L), outdoor terminal block (1), outdoor bushing (2), mounting flange (3), coupling sleeve (4) and indoor bushing (5), it is characterized in that described Main Insulation Structure of Electric is by a copper pipe (8) and twines on it, and accompany the organic film (7) of aluminium platinum (6) and the no oil-insulation combination that insulator is formed.
According to this high pressure dry wall bushing of above conceptual design, compare with oil-paper high-voltage wall bushing commonly used at present, can satisfy the requirement on electric performance of high voltage substation to support fitting; Also bring convenience simultaneously, alleviate the operation maintenance workload to operation maintenance, and since the high-voltage device oil in the cancellation cavity, the operational reliability of also carrying both free from environmental pollution.
Among the figure: 1-terminal block, the outdoor insulator of 2-, 3-mounting flange, 4-coupling sleeve, the indoor insulator of 5-, 6-aluminium platinum, 7-organic film, 8-copper pipe.
Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.
This high pressure dry wall bushing as shown in the figure, it is to passing through the high voltage substation support fitting of usefulness at present---a kind of innovation of oil-paper high-voltage wall bushing improves.It is made up of terminal block (1), outdoor bushing (2), mounting flange (3), coupling sleeve (4), indoor bushing (5) and the main insulation fuse L of outside.Its improvement mainly shows two aspects, the one, and described outdoor bushing (2), indoor bushing (5) comes quite by the porcelain sleeve pipe; The 2nd, main insulation fuse L is by a copper pipe (8) and be wrapped on this copper pipe and a multilayer concentric column that therebetween has several layers aluminium platinum (6) is formed, and forms the hermetically sealed Main Insulation Structure of Electric of dry type of a not filling transformer oil thus with indoor bushing (5), outdoor bushing (2).
This Main Insulation Structure of Electric is according to the capacitor voltage equalizing principle, rolled by organic film and aluminium platinum to form, and under the seal protection of high voltage porcelain bushing, the inner space just has only normal air, so can effectively overcome the number of drawbacks of the low high-voltage wall bushing of oil immersion.
