Embodiment 1

[0028] see figure 1 , a detectable fiberglass insulating bushing for a transformer, comprising a pipe body 1, a sleeve joint 2 is fixedly installed on the left end of the pipe body 1, a fixed disk 3 is fixedly installed on the right end of the pipe body 1, and the inside of the sleeve joint 2 is fixedly installed There is a connection plate 4, the connection plate 4 is conductive design, and an insulating layer is fixedly installed between the connection plate 4 and the pipe body 1. When the insulation layer leaks, the current passes through the electromagnetic block 6, and the current on the electromagnetic block 6 increases, then the magnetic become stronger, and then approach to the right end, in the process of approaching, it will drive the connecting rod 8 and the arc-shaped plate 9 to move to the right together, so that the friction wheel 10 first detects the mechanism to approach, realizing the effect of automatic detection, the up and down of the connecting plate 4 Bot...

Embodiment 2

[0030] see figure 1 , 2 , a detectable fiberglass insulating bushing for transformers, including a pipe body 1, a sleeve joint 2 is fixedly installed on the left end of the pipe body 1, the upper and lower ends of the sleeve joint 2 are designed to be uneven, and the upper and lower ends of the sleeve joint 2 Both are fixedly installed with a limit mechanism 11, and the limit mechanism 11 includes: a fixed rod 1101, and the end surface of the fixed rod 1101 away from the connecting plate 4 is slidably connected with a sliding rod 1103 through a connecting spring 1102, and the opposite side of the sliding rod 1103 is articulated with an arc. There is a support rod 1105 slidingly connected between the arc-shaped backing plate 1104 and the sleeve joint 2. When it is inserted into the pipe body 1 through the sleeve, the inner wall of the sleeve will squeeze the arc-shaped backing plate 1104. After receiving the extrusion force, the arc backing plate 1104 drives the sliding rod 11...

Embodiment 3

[0032] see figure 1 , 3 , 4. A detectable fiberglass insulating bushing for transformers, including a pipe body 1, a sleeve joint 2 is fixedly installed on the left end of the pipe body 1, a fixed disk 3 is fixedly installed on the right end of the pipe body 1, and the inside of the fixed disk 3 The rotation is connected with evenly distributed rotating rods 301, and the rear end of the rotating rod 301 is rotatingly connected with a fastening bolt 302, and the inner rotation of the fixed disk 3 is connected with a rotating shaft 303, and the outer end of the rotating shaft 303 is fixedly equipped with a wedge-shaped plate 304, wedge-shaped The plate 304 is fixed with an arc-shaped tooth plate 305 on the end face far away from the rotating shaft 303. During the installation process, the fixed plate 3 is placed on the transformer, and then aligned with the bolt holes, and then the wedge-shaped plate 304 is rotated. Drive the arc-shaped tooth plate 305 to rotate together, and t...

Abstract

The invention relates to the technical field of insulating sleeves, and discloses a detectable glass fiber reinforced plastic insulating sleeve for a transformer, the detectable glass fiber reinforced plastic insulating sleeve comprises a pipe body, the left end of the pipe body is fixedly provided with a sleeve joint, the right end of the pipe body is fixedly provided with a fixed disc, and the sleeve joint is internally and fixedly provided with a connecting plate; guide rail rods are fixedly mounted at the upper end and the lower end of the connecting plate, electromagnetic blocks are slidably connected to the guide rail rods, and reset springs are fixedly mounted between the right ends of the electromagnetic blocks and the guide rail rods. According to the detectable glass fiber reinforced plastic insulating sleeve for the transformer, in the installation process, the fixing disc is placed on the transformer, then the fixing disc is aligned with a bolt hole, and then a wedge-shaped plate is rotated, so that an arc-shaped toothed plate can be driven to rotate together, then when the arc-shaped toothed plate passes through a rotating rod, the rotating rod can be driven to rotate, and then the rotating rod drives a fastening bolt to rotate; therefore, the effect of fixing the fixing disc is achieved.

Description

technical field [0001] The invention relates to the technical field of insulating bushings, in particular to a detectable fiberglass insulating bushing for transformers. Background technique [0002] Most of the insulation accidents in transformers are caused by bushings. For a long time, users have always hoped that the insulation state of transformer bushings can be detected online, so the detection of transformer insulation bushings is of great significance. [0003] At present, during the use of transformer bushings, the stability of the bushings is not high. After a long period of use, the bushings will fall off from the transformer, resulting in a short circuit in the transformer line, and most of the current bushing installations are escaped. The way of bolt connection is tightened by multiple bolt holes. This fixing method is prone to fall off, and each time it needs to be tightened separately during use, which brings great trouble to installation and maintenance. ...
