Abstract

The present invention provides a high-performance thimble seat housing. The housing comprises a flange I, a barrel, a ball head, a supporting column module and an inflation hole flange; the flange I and the ball head are respectively welded and fixedly connected with two ends of a main barrel; the supporting column module is formed by an integrated supporting column I and a supporting column flange; the supporting column is welded and fixedly connected with the end portion of the supporting column II at the side wall of the ball head; the inflation hole flange is welded and fixedly connected with the outer surface of the side wall of the barrel; the side wall of the inflation hole flange is opened, the opening is extended towards the outside to form the supporting column II, and the side wall of the ball head is connected with the supporting column II in arc smooth connection mode. The further improvement is that: the end face, towards the outside, of the flange I is recessed to form agroove, the inner end face of the groove forms an inner seal face; the inflation hole flange is provided with a seam allowance, the seam allowance is inserted into an inflation hole at the side all of the barrel, and the inflation hole flange is in internal and external welding and fixing with the barrel. The high-performance thimble seat housing can avoid generation of stress and electric discharge phenomena at the connection of the supporting column II and the side wall of the ball head so as to effectively protect the seal surface of the flange I, and the seal is reliable.

Description

Technical field

[0001] The invention relates to the field of high-voltage substations, and in particular to a casing socket housing. Background technique

[0002] The casing housing is a relatively important housing in the high-voltage substation housing, and has strict requirements on surface quality, internal quality and tightness. The existing casing seat housing includes flange I, a cylinder, a spherical head, a supporting cylinder assembly, and an inflation hole flange; the flange I and the spherical head are respectively welded and fixedly connected to both ends of the main cylinder; the supporting cylinder assembly is integrated The support tube I and the flange of the support tube are formed. The support tube I is welded and fixedly connected to the end of the support tube II of the side wall of the spherical head; the inflation hole flange is welded and fixedly connected to the outer surface of the side wall of the cylinder. The main defects of the seat shell are: the s...
