Embodiment 1
[0016] Such as figure 1 As shown, an amorphous transformer built-in high-voltage bushing of the present invention includes a high-voltage bushing, and the high-voltage bushing is fixed on the box cover 1. The middle part of the high-voltage bushing is provided with a high-voltage bushing collar 2, and the high-voltage bushing is clamped. The outer diameter of the ring 2 is smaller than the outer diameter of the high-voltage bushing. The high-voltage bushing is divided into the outer section 3 of the high-voltage bushing and the inner section 4 of the high-voltage bushing through the collar 2 of the high-voltage bushing. The outer section 3 of the high-voltage bushing is arranged outside the box cover 1. , the inner section 4 of the high-voltage bushing is set inside the box cover 1, and a card seat 5 is provided between the bottom periphery of the outer section 3 of the high-voltage bushing and the box cover 1, and a sealing ring 6 is provided between the card seat 5 and the bo...

The invention relates to a built-in type high-voltage sleeve of an amorphous transformer. The built-in type high-voltage sleeve comprises a high-voltage sleeve, wherein the high-voltage sleeve is fixed on a box cover, a high-voltage sleeve clamping ring is arranged at the middle position of the high-voltage sleeve, the external diameter of the high-voltage sleeve clamping ring is smaller than the external diameter of the high-voltage sleeve, the high-voltage sleeve is divided into a high-voltage sleeve external segment and a high-voltage sleeve internal segment by the high-voltage sleeve clamping ring, the high-voltage sleeve external segment is arranged outside the box cover, the high-voltage sleeve internal segment is arranged in the box cover, a clamping seat is arranged between the periphery of the bottom part of the high-voltage sleeve external segment and the box cover, a limitation element is arranged between the high-voltage sleeve internal segment and the box cover, and a stop spring is arranged between the limitation element and the high-voltage sleeve internal segment. Compared with the prior art, the built-in type high-voltage sleeve has the following advantages of good tightness, high fixity, more excellent electrical property and simple overall structure, external press feet and firm elements are eliminated, material investment is reduced, and meanwhile, an installation piece is also simplified.
Description
technical field [0001] The invention relates to a built-in high-voltage bushing of an amorphous transformer, which belongs to the technical field of amorphous transformers. Background technique [0002] The capacitive bushing is an outlet device that leads the high-voltage wire inside the transformer to the outside of the oil tank. It not only serves as the ground insulation of the lead wire, but also plays the role of fixing the lead wire. It is one of the important accessories of the transformer. In the prior art, the installation of high-voltage bushings mainly uses presser feet and solid parts to install and fix, and both the presser feet and the strong parts are located outside the box cover, which not only increases the installation workload, but also has a certain impact on the appearance. [0003] Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0004] The invention provides a built-in high-voltage bus...
