Embodiment Construction

[0029] Further illustrate the embodiment of the present invention below in conjunction with accompanying drawing: please see accompanying drawing,

[0030] Serial numbers 1 to 6 show the components of the composite insulating bushing of the embodiment, and serial numbers 7 to 12 show the components related to this example. The composite insulating bushing of this example is suitable for use in American box-type transformers with a voltage level of 35KV.

[0031] The components of the embodiment are as follows: 1 is the conductive rod, which is located at the central axis of the structure and is connected to the outer cable and the inner coil of the transformer; 2 is the insulating core, which is hooped on the 0.4L long section of the conductive rod, which is its internal pressure resistance The first line of defense for insulation; 3 is the insulating umbrella, which is laminated on the outer layer of the composite member of the conductive rod and the insulating core, which is ...

Abstract

The invention discloses a composite insulated sleeve, which comprises a conductive rod, an insulated core, an insulated umbrella, a sealing ring, an equalizing sleeve and a wiring nut, and is characterized in that: continuous annular grooves are formed on outside diameter surface of the conductive rod with in a length L covered by the insulated umbrella; and the insulated core is looped on at least a section with a length of more than or equal to 0.4 L and the insulated umbrella is compounded outside the insulated core. The method for manufacturing the composite insulated sleeve mainly comprises the following technical steps: 1, processing the conductive rod and performing the antioxidative processing of the conductive rod; 2, manufacturing a composite member in which the insulated core is looped on the conductive rod; 3, drying the composite member; 4, plasticizing the insulated umbrella; and 5, assembling the composite insulated sleeve. The composite insulated sleeve is applicable to American box transformers and is particularly applicable to external cables of wind power generation American box transformers.

Description

technical field [0001] The invention relates to a composite insulating bushing suitable for an American-style box-type transformer, which aims at the improvement of the prior art in terms of structure simplification and functional refinement. Background technique [0002] At present, the bushings used in American box-type transformers in the domestic transformer industry mostly follow the similar products in the "Transformer Components" drawing compilation (1) compiled by Shenyang Transformer Factory in October 1976. Of course, the design in the 1970s has already many deficiencies; [0003] 1. Existing technology with complex structure; compile P according to the drawing 11 There are as many as 29 types of components of the BJ35KV / 400A bushing, but there are only 6 types of main components in the present invention. In contrast, they are simple and clear, and the structure needs to be simplified. [0004] 2. The existing technology has insufficient functional reliability; t...
