Embodiment 1

[0027] Such as Figure 1-3 Shown is a detachable bushing online monitoring connection clip of the present invention.

[0028] A detachable bushing on-line monitoring connection clip, comprising:

[0029] Including a pipe sleeve 1, on the pipe wall of the pipe sleeve 1, there are two axial holes 11 arranged radially and oppositely, and on the pipe sleeve 1, a slideway 3 is provided at the wall of the shaft hole 11 , the slideway 3 is provided with a fixing hole 31 .

[0030] Hollow buttons 2 that can be pressed multiple times with openings pointing to the axis of the sleeve 1 are respectively provided in the two shaft holes 11, and the hollow buttons 2 include an insertion part 21 for connecting with the fixing hole 31. The insertion parts 21 are symmetrically provided with resetting and fixing bars 22 relatively movable relative to the center of the hollow button 2 , and the resetting and fixing bars 22 are connected with the fixing holes 31 .

[0031] The hollow button 2 i...

Embodiment 2

[0035] Based on embodiment 1, the difference from embodiment 1 is:

[0036] The clamping piece 51 is an arc-shaped clamping piece, and the center of the outer arc surface of the clamping piece 51 is respectively provided with a shaft 52 perpendicular to the clamping piece 51, and the shaft 52 passes through the limiter. The bit ring 7 is inserted into the hollow button 2, and the clamping member 51 is pushed or pulled back by the shaft 52 to realize the relative movement between the clamping device 5 and the connecting column 0, so that the clamping device 5 can be replaced when necessary. Or the removal of the detachable sleeve on-line monitoring connection clip is not destroyed during maintenance. At the same time, the connecting column 0 is further protected, and the connecting column 0 may be damaged when the traditional connecting clip is removed.

[0037] Both the reset slider 61 and the second elastic member 62 are movable relative to the limit ring 7, ensuring that th...

Abstract

The invention relates to a power line clamp, in particular to a detachable bushing online monitoring connection clamp. The detachable bushing online monitoring connection clamp comprises an insertionportion, wherein reset fixing strips are symmetrically disposed on the insertion portion and are movable relative to the center of a hollow button; the reset fixing strips are connected with a fixinghole; the hollow button is connected to a clamping device for clamping a connecting post in a bushing through a first elastic member; the clamping device comprises a clamping member connected to the connecting post and is connected to the hollow button by a resetting device; the resetting device comprises a reset slide block connected to the first elastic member and a second elastic member connected to the clamping device; and the reset slide block and the second elastic member are disposed in a stopping ring. The detachable bushing online monitoring connection clamp has a reset function, canbe used repeatedly, and is convenient to replace and maintain.

Description

technical field [0001] The invention relates to a power line clamp, in particular to a detachable casing online monitoring connection clamp. Background technique [0002] The existing on-line monitoring technology mostly adopts hard connection to obtain the pulse signal through the end screen of the transformer bushing to realize the signal extraction and grounding at the same time. There is an unavoidable problem in this extraction method, that is, it requires the construction personnel to fasten the force and The specifications and dimensions of the grounding device must be consistent with the factory settings of the primary equipment to ensure reliable contact. [0003] The domestic invention patent with the application number CN106066409A discloses a current transformer end screen clamp, which provides a current transformer end screen clamp with a firm clamping structure, which can prevent falling off, save time and effort for installation, and improve work efficiency. ...
