Description

Height-adjustable insulating sleeve

Technical Field

The utility model belongs to the technical field of power equipment, especially, relate to an insulation support of adjustable height.

Background

Compared with the traditional air-insulated switch cabinet, the gas-insulated metal-enclosed switch cabinet (C-GIS for short) has more compact structure and safer and more reliable operation, and is widely applied to the field of power transmission and distribution. At present, a large number of insulating sleeves are used in a gas insulated metal enclosed switch cabinet (C-GIS for short), and the insulating sleeves mainly have the functions of sealing gas, passing large current and electrically isolating. The intermediate conductor and the outer insulation of a conventional bushing of this type are cast together, as shown in fig. 1: insulating pouring body and intermediate conductor pouring in an organic whole, unable relative movement, the conductive copper bar size requirement to the bending rather than being connected is very high during the overall assembly, causes the assembly degree of difficulty big and assembly quality can't guarantee.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an insulation support of adjustable height to the size of conductive copper bar and insulating pouring body and intermediate conductor is difficult to the accurate matching among the solution prior art, and the assembly degree of difficulty that causes is big and the problem that assembly quality can't be guaranteed.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides an insulating sleeve of adjustable height, includes insulating pouring body and intermediate conductor, the inside axial of insulating pouring body is equipped with the passageway that can pass through intermediate conductor, the inner wall of insulating pouring body is fixed with the inlay, the surface of intermediate conductor is equipped with axial spout, inlay sliding connection is in the spout.

Furthermore, the two sides of the sliding groove on the middle conductor are respectively provided with a boss and a check ring for limiting the moving range of the inlay.

Further, a sealing ring is arranged in the sliding groove.

Further, the distance between the boss and the retainer ring is 0-5mm longer than the axial length of the inlay.

Further, the inlay is tubular, and the periphery of the inlay is fixed on the inner wall of the insulating casting body; the spout distributes in the circumference of intermediate conductor outer wall.

The working principle of the technical scheme is as follows: and moving the two intermediate conductors to enable the intermediate conductors and the insulating pouring body to move relatively, so that the positions of the two intermediate conductors are adjusted, and the two ends of the lead copper bar can be accurately connected and assembled with the two intermediate conductors.

The beneficial effects of this technical scheme lie in: the position of this technical scheme through nimble regulation intermediate conductor to reach the good assembly of intermediate conductor and conductive copper bar, avoided among the prior art because conductive copper bar's the precision of bending is not high, its length size has great deviation usually, consequently can appear the conductive copper bar short in intermediate conductor and conductive copper bar assembling process and cause the condition that the contact is not arrived or the unable assembly of overlength. The sealing ring can enable the inlay to be tightly matched with the middle conductor, and the loosening condition is avoided. And the arrangement of the lug boss and the check ring can effectively limit the moving range of the middle conductor.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the insulation pouring body 1, the intermediate conductor 2, the inlay 3, the sealing ring 4, the retainer ring 5, the metal flange 6, the cabinet combining conductor 7, the air box 8 and the conductive copper bar 9.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment is basically as shown in the attached figures 2-3: the utility model provides an insulating sleeve of adjustable height, includes insulating pouring body 1 and intermediate conductor 2, and the inside axial of insulating pouring body 1 is equipped with the passageway that can pass through intermediate conductor 2, and insulating pouring body 1's inner wall is fixed with pipy inlay 3, and intermediate conductor 2's surface is equipped with axial spout, and the spout distributes in the circumference of intermediate conductor 2 outer wall, and inlay 3 sliding connection is equipped with sealing washer 4 in the spout. The both sides of spout are equipped with boss and retaining ring 5 that are used for restricting the inlay 3 moving range respectively on the intermediate conductor 2, and the distance between boss and the retaining ring 5 is longer 0-5mm than the axial length of inlay 3.

The assembly of the insulating sleeve inside the gas box 8 requires the following components: the combined cabinet comprises a conductive copper bar 9, two groups of metal flanges 6, a combined cabinet conductor 7 and an insulating sleeve. Two groups of metal flanges 6 respectively assemble two groups of insulation pouring bodies 1 on the opposite inner walls of the air boxes 8, the cabinet combining conductor 7 is connected with the intermediate conductor 2 through the contact finger to realize main loop communication, and the intermediate conductor 2 is connected with the conductive copper bars 9 through bolts to realize main loop communication. Because the precision of bending of copper busbar 9 is not high, its length dimension has great deviation usually, consequently can appear in intermediate conductor 2 and the 9 assembling process of copper busbar that the copper busbar 9 is short excessively and cause the condition that the contact can not be arrived or the unable assembly of overlength, move the position of adjusting intermediate conductor 2 through two directions this moment, easily realize the good assembly of intermediate conductor 2 and copper busbar 9, the assembling process need not to repair spare part, labour saving and time saving.
