Abstract

The invention provides a processing method for producing a fastening device. The device comprises: an open annular body; a first matching part located at one end of the body; a second matching part located at the other end of the body and adapted to the first matching part; The first matching part and the second matching part are connected, wherein the first matching part and the second matching part are butted together, and the thickness and width of the connecting part are the same as those of the body; the connecting part is sunk into the connecting part for connection. The methods include: shearing: cutting out the unfolding material according to the size of the fastening device; forming: mechanical rolling and bending, and processing into an open ring structure; welding: welding the butt joint into a whole ring; cutting: cutting the whole ring into tenon and mortise The butted second matching part and the first matching part; electrochemical treatment: an oxide film is formed on the surface of the ring body. The fastening device has simple and reasonable structure, convenient installation, no protrusions, small assembly space, simple production process, low production cost, electrochemical surface treatment, and uniform electric field intensity distribution.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a processing method for producing a fastening device. Background technique [0002] The high-voltage transformer core is a pulse power magnetic device that can be applied to transmit energy under an ultra-high voltage electric field of hundreds of kilovolts or megavolts with an equivalent operating frequency above megahertz (MHz). The fastening device used is a product that suppresses or prevents parasitic capacitive coupling of the magnetic core during transformer operation, isolates static electricity or electric field interference, and avoids adverse factors caused by breakdown between high-voltage electrical components. [0003] The existing high-voltage transformer magnetic core fastening device is mainly based on full circle or air gap auxiliary fixing. Among them, such as figure 1 As shown, the full circle is a closed structure, which has the advantages of sim...
