The utility model is described in further detail combined with specific embodiments below:
Referring to shown in attached drawing 1 to attached drawing 4, the utility model is a kind of clamp insulation structure of for transformer, includes
Folder, wherein folder is divided into high-pressure side folder 1 and low-pressure side folder 2；High-pressure side folder 1 and low-pressure side folder 2 are respectively arranged at
The iron yoke two sides for the transformer core being preset with are to play fixation to transformer core；Specifically, 1 group of high-pressure side folder
It include high-pressure side upper clamping piece and high-pressure side lower clamping piece, 2 groups of the low-pressure side folder includes under low-pressure side upper clamping piece and low-pressure side
Folder, high-pressure side upper clamping piece and low-pressure side upper clamping piece grip the upper yoke of transformer core, and high-pressure side lower clamping piece and low
Pressure side lower clamping piece grips the lower yoke of transformer core.
In the present embodiment, multiple connectors 3 have been bolted between high-pressure side folder 1 and low-pressure side folder 2,
In, offer the installation through-hole passed through for bolt on high-pressure side folder 1 and low-pressure side folder 2, and any one connector 3
Both ends offer the threaded hole screwed in for bolt, and when installation, connector 3 is put into high-pressure side folder 1 and low-pressure side folder 2
Between, the threaded hole at the both ends of connector 3 respectively with the installation through-hole same axis pair on high-pressure side folder 1 and low-pressure side folder 2
Together, bolt is then passed through corresponding installation through-hole respectively to screw in into corresponding threaded hole, that is, completes a connector 3
Installation, in this way, multiple connectors 3 are parallel to be installed between high-pressure side folder 1 and low-pressure side folder 2, specifically, high pressure
Connector 3 between side upper clamping piece and low-pressure side upper clamping piece is supporting element, and between high-pressure side lower clamping piece and low-pressure side lower clamping piece
Connector 3 be feet, meanwhile, be fixed with pulling plate by welding between high-pressure side upper clamping piece and high-pressure side lower clamping piece,
Pulling plate is fixed with also by the mode of welding between low-pressure side upper clamping piece and low-pressure side lower clamping piece.
It in the present embodiment, include the bolt company for being set to connector 3 and high-pressure side folder 1 or low-pressure side folder 2
Connect the insulation assembly 4 at place；The insulation assembly 4 includes insulating sleeve 41, the insulating barrier that one end forms circular square ring 411
43 and insulating washer 42；Insulating sleeve 41 is set between bolt and installation through-hole and is come so that bolt to be isolated with folder,
Specifically, insulating sleeve 41 is cylindrical, and outer surface is in contact with installation through-hole inner wall, and the cylinder of its inner surface and bolt
It is in contact to realize being isolated between bolt and folder；Meanwhile 411 block of circular square ring of insulating sleeve 41 is logical in installation
At the port of hole, wherein the length of the insulating sleeve 41 and the equal length of installation through-hole；Insulating washer 42 be sheathed on bolt and
