Abstract
The invention relates to the field of high-voltage electrical equipment, in particular to a hollow composite insulator capable of being used for high-voltage direct current transmission and a connecting flange of the hollow composite insulator. The hollow composite insulator comprises an insulation sleeve barrel and the connecting flange, the connecting flange comprises a flange shaft, an elastic tightening structure is arranged on the peripheral face of the flange shaft, and the elastic tightening structure is tightened between the flange shaft and the insulation sleeve barrel. Due to the fact that the elastic tightening structure is arranged on the peripheral face of the flange shaft of the hollow composite insulator, and the elastic tightening structure is tightened between the flange shaft and the insulation sleeve barrel, the elastic tightening structure can be compressed once the flange shaft is inserted into the insulation sleeve barrel, therefore, a connecting shaft and the insulation sleeve barrel are firmly combined, the connecting flange is prevented from being drawn out of the insulation sleeve barrel, and therefore the problem that the insulation sleeve barrel and the connecting flange of an existing hollow composite insulator are connected loosely is solved.
Description
Technical field
The present invention relates to high-voltage electrical apparatus field, particularly relate to a kind of hollow combined insulator and adpting flange thereof that can be used for high voltage direct current transmission.
Background technology
In high-voltage transmission equipment, hollow combined insulator is a kind of and general parts.Current hollow combined insulator is all by the insulating sleeve of tubular with form with the adpting flange that insulating sleeve is fixedly assembled together, adpting flange comprises ring flange and is positioned at the flange shaft of ring flange one side, wherein between adpting flange and insulating sleeve, by its flange shaft, is fixed together.Flange shaft stretches to one end of insulating sleeve, its with fixed form between insulating sleeve have bonding, be threaded, interlocking etc. is several.
In the situation that the length specification of insulator is less, connected mode between above-mentioned flange shaft and insulating sleeve all can meet the demands, but, if run into, length is grown or the insulator of preponderance, between insulating sleeve and adpting flange, just can make because of factors such as flexible deformations the loosening disengaging of insulating sleeve and adpting flange, and then cause the inefficacy of insulator self mechanical property or electric property.
Generally speaking, current hollow combined insulator exists insulating sleeve to be connected not firm problem with adpting flange.
Summary of the invention
The object of the present invention is to provide a kind of hollow combined insulator, to solve the insulating sleeve that current hollow combined insulator exists, be connected not firm problem with adpting flange.
In addition, the present invention also aims to provide the adpting flange of above-mentioned hollow combined insulator.
In order to address the above problem, hollow combined insulator is by the following technical solutions: hollow combined insulator, comprise insulating sleeve and adpting flange, and adpting flange comprises flange shaft, the outer peripheral face of flange shaft is provided with elastic expansion locking structure, and the swelling of elastic expansion locking structure is between flange shaft and insulating sleeve.
Described elastic expansion locking structure has formed the hangnail structure of flange shaft.
Described elastic expansion locking structure is ring fin.
Described ring fin has more than two, and each ring fin has formed glue groove along between the axial distribution of flange shaft and adjacent two ring fins, in glue groove, is filled with adhesive glue.
Described elastic expansion locking structure consists of the fin on flange shaft outer peripheral face spaced apart.
The adpting flange of hollow combined insulator is by the following technical solutions: the adpting flange of hollow combined insulator, comprise flange shaft, and the outer peripheral face of flange shaft is provided with elastic expansion locking structure.
Described elastic expansion locking structure has formed the hangnail structure of flange shaft.
Described elastic expansion locking structure is ring fin.
Described ring fin has more than two, and each ring fin has formed glue groove along between the axial distribution of flange shaft and adjacent two ring fins.
Described elastic expansion locking structure consists of the fin on flange shaft outer peripheral face spaced apart.
Because the outer peripheral face of the flange shaft of this hollow combined insulator is provided with elastic expansion locking structure, the swelling of elastic expansion locking structure is between flange shaft and insulating sleeve, once therefore flange shaft is inserted into insulating sleeve, elastic expansion locking structure just can be compressed, thereby connecting axle and insulating sleeve are combined firmly, prevent that adpting flange from being extracted out from insulating sleeve, and then solved the insulating sleeve that current hollow combined insulator exists and be connected not firm problem with adpting flange.
Further, hangnail structure can play the effect of blocking insulating sleeve, further increases the reliability of combination between adpting flange and insulating sleeve.

Embodiment
The embodiment 1 of hollow combined insulator, as Figure 1-3, this hollow combined insulator comprises insulating sleeve 101 and adpting flange 102.
The structure of insulating sleeve 101 is prior art, and it will not go into details herein.
Adpting flange 102 comprises ring flange 11 and flange shaft 12, the outer peripheral face of flange shaft 12 is provided with elastic expansion locking structure, the swelling of elastic expansion locking structure is between flange shaft 12 and insulating sleeve 101, in the present embodiment, what elastic expansion locking structure specifically adopted is ring fin 13, ring fin 13 has a plurality of and has formed the hangnail structure in flange shaft 12 simultaneously, in addition, between two adjacent ring fins, formed glue groove, in glue groove, be filled with adhesive glue 103, adhesive glue 103 has played the effect of bonding flange shaft 11 and insulating sleeve 101.
When assembly connection flange, can first in the flange shaft 12 of adpting flange 102, smear adhesive glue 103, then flange shaft is inserted in insulating sleeve, in the process of inserting, compressed and the swelling of elastic expansion locking structure is between flange shaft and insulating sleeve, in this simultaneously, the elastic expansion locking structure that has formed hangnail structure " is caught " inwall of insulating sleeve firmly, and it also can play the effect that stops adpting flange to be drawn out of.
The embodiment 1 of hollow combined insulator, as shown in Fig. 4-5, this embodiment and above-described embodiment 1 difference be only, described elastic expansion locking structure consists of the fin on flange shaft outer peripheral face spaced apart.
The embodiment 1 of the adpting flange of hollow combined insulator, the structure of the adpting flange of this hollow combined insulator is identical with the structure of adpting flange in the embodiment of above-mentioned hollow combined insulator 1, and it will not go into details herein.
The embodiment 2 of the adpting flange of hollow combined insulator, the structure of the adpting flange of this hollow combined insulator is identical with the structure of adpting flange in the embodiment of above-mentioned hollow combined insulator 2, and it will not go into details herein.
