Abstract

The utility model provides an isolated-phase bus insulator, which has good sealing structural performance and more reliable properties, is energy-saving and, can be used to greatly reduce leakage rate and decrease operating frequency of inflation equipment. The utility model adopts the following technical scheme: an isolated-phase bus insulator comprises an outer shell, a conductor arranged inside the outer shell, an outer shell flange positioned on the inner wall of the outer shell, a conductor flange disposed outside the conductor and an insulator mounted between the outer shell and the conductor. The isolated-phase bus insulator is characterized in that: the insulator is a wave-like disk type insulator; the outer ring of the insulator is detachably connected with the outer shell flange through a first connector; the inner ring of the insulator is detachably connected with the conductor flange through a second connector; a first sealing element is arranged between the outer ring of the insulator and the outer shell flange; and a second sealing element is arranged between the inner ring end portion of the insulator and the conductor flange.

Description

Separated phase enclosed bus insulator

Technical field

The utility model relates to a kind of separated phase enclosed bus insulator, belongs to the high-tension transmission equipment technical field.

Background technology

There is encapsulating method miscellaneous in present stage in bus bar products, but is all generally depositing this or that shortcoming, and main manifestations is: level and smooth sealing plate is adopted in general enclosed busbar sealing, and is poorly sealed, shines into the interior released gas rate of bus high; Product is immature, the frequent replacing; Due to general sealing plate material be rubber, have a service life short, the defective such as mechanical strength is low under the impact of weather and external force, has increased again uncertainty to the safe operation of bus.

The utility model content

The purpose of this utility model is to provide a kind of separated phase enclosed bus insulator, and hermetically-sealed construction is functional, greatly reduces leak rate, has reduced the frequency of utilization of charger, energy-conservation, more reliable performance.

To achieve these goals, the utility model is by the following technical solutions:

a kind of separated phase enclosed bus insulator, comprise shell, conductor in the enclosure is set, be positioned at the shell flange on outer casing inner wall, be arranged on conductor outer conductor flange and the insulator between shell and conductor, it is characterized in that: described insulator is the disk insulator that ripple glaze is arranged, removably connect by the first connector between insulator outer ring and shell flange, removably connect by the second connector between insulator inner ring and conductor flange, be provided with the first seal between insulator outer ring and shell flange, be provided with the second seal between insulator inner ring end and conductor flange.

Further, the shell flange has seal groove, and seal groove is arranged on the lower surface of shell flange, and inboard near the shell flange, and the first seal is arranged in seal groove.

Further, the shell flange outside has blind hole, and insulator has through hole on the outer ring, and the first connector comprises the first bolt bullet pad and plain cushion, and the first bolt is inverted, and passes successively bullet pad, plain cushion, through hole and is connected with blind hole.

Further, have inner via hole on the conductor flange, have interior blind hole on the insulator inner ring, the second connector comprises the second bolt, interior bullet pad and interior plain cushion, and the second bolt is inverted, and passes successively interior bullet pad, interior plain cushion, inner via hole and is connected with interior blind hole.

Further, the insulator material is resin.

Further, the first seal and the second seal are the double flute sealing ring.

The beneficial effects of the utility model:

The disk insulator of ripple glaze makes creepage ratio apart from having increased by 2 times, makes electric equipment operation safer; Be provided with the first seal between insulator outer ring and shell flange, be provided with the second seal between insulator inner ring end and conductor flange, hermetically-sealed construction is functional, greatly reduces leak rate, has reduced the frequency of utilization of charger, energy-conservation, more reliable performance.
