The invention discloses an off-host insulation material general assembly. The off-host insulation material general assembly comprises a paper cylinder, an internal encircling cylinder, an external encircling cylinder, internal support strips, main support strips, external support strips, internal angular rings, external angular rings, lower angular rings, iron yoke end rings, electrostatic rings and latch cushion blocks, wherein the iron yoke end rings sleeve outer sides of lower end parts of the paper cylinder, a plurality of internal support strips are vertically fixed at the middle part of an outer wall of the paper cylinder at a certain distance, the internal encircling cylinder is arranged outside the internal support strips, the main support strips are vertically arranged on an outer side wall of the internal encircling cylinder at a certain distance, the internal angular rings are arranged at a lower end of the internal encircling cylinder, a line cake is arranged outside the main support strips, the external encircling cylinder is arranged outside the line cake, the external support strips are arranged on an inner wall of the external encircling cylinder and are corresponding to the main support strips, the external annular rings are arranged at an inner side of the external encircling cylinder, and a lead angular ring and a lead pipe are arranged on the internal angular rings above and below the line cake. In the off-host insulation material general assembly, an insulation element of an extra / ultra high-voltage transformer is completely assembled, the package and transportation cost is greatly reduced, and the production efficiency of the transformer is improved.
Description
technical field [0001] The invention relates to a transformer insulating part, in particular to an insulating material assembly separated from a main machine. Background technique [0002] The rated voltage of ultra-high voltage transformers is 350KV-500KV, and the rated voltage of ultra-high voltage transformers is above 750KV. The insulating parts of EHV and UHV transformers include many insulating parts, and the assembly of insulating parts is very cumbersome. In the prior art, the insulating parts of EHV and UHV transformers are all produced by insulating part manufacturers, and then dispersedly packaged and transported to the transformer Manufacturers and transformer manufacturers need to assemble these insulating parts together before they can be wound on the winding machine. Because the shapes of insulating parts are different, the packaging takes up a lot of space, which greatly increases the cost of packaging and transportation. Moreover, for transformer manufactur...
