An electrical bushing based on multiple protection

Abstract

The invention provides an electric sleeve based on multiple protection. The electric sleeve comprises a first assembly pipe sleeve, a silicone rubber umbrella sleeve, a threaded head, a first sealingring, a second assembly pipe sleeve, a connecting flange, a sealing cover, a second sealing ring, an inlet and outlet hole, an adjustable connection pipe head structure, a third assembly pipe sleeve,an external thread, a shock-resistant and pressure-reducing connection ring frame structure, a multiple protection socketed pipe structure and an adjustable assembly connecting frame structure, wherein the silicone rubber umbrella sleeve is integrally arranged on an outer wall of the first assembly pipe sleeve; the threaded head is threaded between the first assembly pipe sleeve and the second assembly pipe sleeve; and the connecting flange is integrally arranged on an outer wall of the second assembly pipe sleeve. The electric sleeve has the beneficial effects that staff can tilt the sleeve and an adjusting ball to different angles conveniently through the adjustable connection pipe head structure. At the same time, an internal copper wire can be used at different angles, thereby increasing the function of the adjustable connecting pipe head structure.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to an electrical bushing based on multiple protections. Background technique [0002] Bushings are hollow electrical insulators through which conductors can pass and are used where high voltage lines must pass through walls or other surfaces on switchgear, transformers, circuit breakers and other high voltage installations, such as by For passing high voltage lines from oil-filled transformers, whereby the bushing is an oil-to-air bushing, part of which is in the oil inside the transformer and part in the air outside the transformer, and the other bushing is an air-to-air bushing , such as through the wall to pass through the high-voltage line, the prior art is the technical solution adopted by an electrical bushing with Chinese Patent Publication No. a first longitudinal end at the top and a second longitudinal end configured at the bottom of a sleeve configured to receive an...
