Problems solved by technology
However, the existing upper insulating plate of the liner is provided with an installation groove on one side, and the insulating plate is snapped onto the insulating ceramic sleeve by using the installation slot. This type of snapping installation is not firm and has poor stability, requiring other auxiliary equipment Fixing the insulating ceramic bushing and the gram insulating plate makes it inconvenient to install and disassemble the gram insulating plate, and affects the use of the insulating ceramic bushing during disassembly, so the present invention provides a gram insulating plate to solve the above problems

The invention discloses a link insulating board. The board comprises a first link insulating board, a second link insulating board, locking mechanisms and pre-positioning mechanisms. The first and second link insulating boards are spliced and assembled to form a link insulating board whole body. The first and second link insulating boards are provided with the locking mechanisms. One end of the first link insulating board and one end of the second link insulating board are movably hinged through a stainless steel hinge. The other end of the first link insulating board and the other end of thesecond line link insulating board are provided with pre-positioning mechanisms. The number of the locking mechanisms is two. The board is simple and reasonable in structure and convenient to use, andis composed of the first link insulating board and the second link insulating board, so that the link insulating board fixedly clamps an insulating ceramic sleeve, thereby effectively improving the installation firmness of the line link insulating board, and enabling the installation and disassembly of the link insulating board to be convenient without the impact on the use of the insulating ceramic sleeve. Moreover, the practicability is higher.
Description
technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a ring insulation board. Background technique [0002] Linker is also called drop-out insurance and drop-out fuse. It is the most commonly used short-circuit protection switch for branch lines of 10kV distribution lines and distribution transformers. It is installed on branch lines of 10kV distribution lines because it has an obvious disconnection The opening point has the function of isolating switch, creating a safe working environment for maintenance lines and equipment, and increasing the installation of maintenance. Therefore, Lingke has been popularized in 10kV distribution lines and distribution transformers. However, the existing upper insulating plate of the liner is provided with an installation groove on one side, and the insulating plate is engaged with the insulating ceramic sleeve by using the installation groove. This type of engagement is no...
