Problems solved by technology

Therefore, in recent years, porcelain insulators have been gradually replaced, but for some specific towers, such as the porcelain suspension insulator strings passing through the tension rods of existing transmission lines, they cannot be directly replaced by existing composite insulators

Embodiment 1

[0037] A composite insulator installation assembly with adjustable tilt support as shown in FIGS. 1 to 8 , which includes a fixed base plate 1 and a fixed bracket 2 . The fixed frame includes a fixed frame 21 and a movable frame 22 . Bolts are used between the fixed bottom plate and the fixed bracket. The fixed bottom plate is composed of a flat plate, on which a fixing device 11 is arranged. The fixing device is two bolt holes that can be used in conjunction with the U-shaped bolt holes on the cross arm as shown in the figure. Multiple through-holes for use with fixed brackets. The fixed frame is composed of a main board, and the movable frame is composed of a movable plate. The main board is provided with a through hole movably connected with the fixed bottom plate, and a straight plate is erected on the main board. The movable plate is movably connected on the main board, and a connecting device 23 is arranged on the opposite side of the movable plate and the straight pla...

Embodiment 2

[0041] An installation assembly for supporting composite insulators with an adjustable inclination angle as shown in Figures 9 and 10, most of its structure is the same as that of Embodiment 1, except that the connecting device part is changed to a rotatable metal part 31 supporting the upper end of the composite insulator The movable frame 22 fixed on the fixed bracket is a straight plate, and a plurality of through holes for adjusting the inclination are arranged along the circular arc at a certain radius along the rotating shaft 4 between the straight plate and the composite insulator, and the corresponding positions on the supporting composite insulator A matching through hole is provided at the place, and the two are connected with a pin. At the same time, the metal lower end part of the composite insulator is set into a plate shape or a ball head shape.

[0042] Since all parts of the present invention are detachably connected, the parts of Embodiment 1 and Embodiment 2 ...

Embodiment 3

[0045] An installation method of the inclination-adjustable support and post composite insulator assembly as described in Embodiment 2. Firstly, install the fixed bottom plate of the assembly on the cross arm; The connecting device is connected, that is, the metal part of the upper end of the composite insulator is sandwiched between the fixed frame and the movable frame of the fixed bracket, and the appropriate angle is adjusted first, and then locked with bolts; the connection on the metal part of the upper end of the composite insulator in this embodiment The device is an adjustable inclination spline, and then the flat plate or ball head on the metal part of the lower end of the post composite insulator is connected with the suspension clamp on the jumper or the splint or bowl head of the support tube.

Abstract

The invention discloses a supporter with adjustable inclination, a mainstay composite insulator component and an installation method thereof. The invention comprises the supporter with adjustable inclination, a mainstay composite insulator fixed soleplate and a fixed bracket. The fixed soleplate and the fixed bracket are movably connected in a dismountable way; the fixed soleplate is provided with a fixed device which is matched with a cross arm; the fixed bracket is provided with a connecting device; a metal head at the upper end of the composite insulator is provided with a connecting device which is matched with the connecting device on the fixed bracket; the connecting device on the composite insulator is tightly locked with the connecting device at the upper end of the fixed bracket in a relatively rotatable way. The invention has the advantages that the fixed soleplate and the fixed bracket are provided with the fixed device and the connecting device correspondingly and the metal parts at the upper ends and the lower ends of the supporter and the mainstay composite insulator are simply reconstructed to be used as one component, thus being applicable to the replacement of line durable tension-rod jumping-wire ceramic insulator series. Therefore, the insulator of the invention has simple installation and simple application.

Description

technical field [0001] The invention relates to an insulator for a transmission line, in particular to an installation assembly and an installation method for a suspension type ceramic insulator string replacement support and a post composite insulator suitable for a tension rod passing through a line of a transmission line. Background technique [0002] Most of the existing tension rods of transmission lines are fixed with suspended porcelain insulator strings (hereinafter referred to as porcelain insulator strings). Due to the poor self-cleaning ability of porcelain insulators during use, discharges often occur, and they need to be repaired every year. It needs to be cleaned and zero-measured in case of power outage or electrification, so the labor intensity is high and the operation cost is high. In addition, the porcelain insulator string has multiple movable connection points, which are affected by the wind pressure and shifted, which is easy to discharge the tower body....
