Problems solved by technology
[0005] In order to solve the problem that the static contacts and insulating strips of the existing transformer tap changer need to be manufactured separately, they need to be assembled when the tap changer is assembled, which increases the assembly process and reduces the work efficiency. The problem that the installation and connection of the tap head is not firm, the invention provides a manufacturing method for the static contact insulation strip of the off-excitation strip tap changer, which is specially used for manufacturing a new type of off-excitation strip tap changer static contact insulation strip Composite, the method includes the steps of:

The invention relates to a method for manufacturing a static contact and insulation strip composite piece of a non-excited magnetic strip-type tap switch, which belongs to the technical field of manufacturing of large transformer parts and aims to solve the problem that a static contact and an insulation strip of the conventional transformer tap switch need to be manufactured separately. The method for manufacturing the static contact and insulation strip composite piece of the non-excited magnetic strip-type tap switch comprises the following steps: (a) extruding an upper section; (b) assembling the insulation strip; and (c) extruding a lower section to obtain the static contact and insulation strip composite piece of the non-excited magnetic strip-type tap switch. In the method for manufacturing the static contact and insulation strip composite piece of the tap switch, a tubular static contact is adopted and the upper section and the lower section are extruded out by an extruding machine so that the static contact is fixedly connected with the insulation strip into a whole. The method has the advantages of simple structure, compact connection and great reduction of installation processes.
Description
technical field [0001] The utility model belongs to the technical field of manufacturing large-scale transformer accessories, in particular to a method for manufacturing a static contact with an insulating strip in a non-excitation strip tap changer. Background technique [0002] The existing transformer non-excitation strip tap changer is mainly composed of a handwheel control device and a tap device. The moving contact device is fixedly connected to the bar, the rack and the insulating bar are slidably connected through the connecting frame, and the handwheel operating device drives the rack to move relative to the insulating bar through the gear. [0003] The static contact of this tap changer adopts a screw rod, the screw rod passes through the socket on the insulating strip, and two nuts are installed on the threaded section, and the main coil or the tap of the voltage regulating coil wound on the threaded section is clamped by the nuts Or the tap lead wire on the outp...
