Abstract
A composite insulating fully enclosed bus comprises a conductor which may be a copper pipe, an aluminum pipe, a copper rod or an aluminum rod, wherein a first flange is fixedly connected with the front end of the conductor; the first flange is fixedly connected with a first bus connection plate; a second flange is fixedly connected with the rear end of the conductor; the second flange is fixedly connected with a second bus connection plate; a first methyl vinyl silicone rubber insulating layer is encapsulated on the conductor; the outer wall of the first methyl vinyl silicone rubber insulating layer is sleeved with a grounding electric screen layer of a semiconductor material; and a second methyl vinyl silicone rubber insulating layer is encapsulated on the outer wall of the grounding electric screen layer. The all-insulation copper pipe bus adopts silicone rubber as the main insulation, failures of grounding and interphase short circuits caused by external moisture, dust and external objects are basically eliminated, and thus the bus has high reliability. The outer insulation of the insulating bus adopts silicone rubber as the insulation material. Since the silicone rubber has ultraviolet resistance and ageing resistance, the bus can be used both indoors and outdoors, and the service life of the product is over 50 years.
Description
Technical field
The utility model relates to a kind of electric equipment connection conductor, the specifically totally-enclosed bus of a kind of compound inslation.
Background technology
In power plant and transformer station voltage power distribution equipments at different levels, the large shape electric equipment such as generator, transformer is that insulated conductor is realized with being electrically connected of various electric devices, this wire adopts epoxy resin as the totally-enclosed bus of main insulation usually, when low temperature because the metal material in the bus is different with the shrinkage ratio of epoxy resin, cause bus and external insulation layer to produce the gap, thereby affect bus quality and operational reliability.
In addition, ground connection and short circuit accident easily occur without ground screen layer in this wire when animal and the contact of other factor, affect the safe operation of equipment.
The utility model content
The purpose of this utility model provides the totally-enclosed bus of a kind of compound inslation, and its same distance can be very little, thereby reduced floor space, and reliable.
The technical scheme that adopts is:
The totally-enclosed bus of a kind of compound inslation comprises conductor, and conductor is copper pipe, aluminum pipe, copper rod or aluminium bar, it is characterized in that:
Front end at conductor is fixedly connected with the first flange, is fixedly connected with the first bus connecting plate on the first flange; The rear end of conductor is fixedly connected with the second flange, is fixedly connected with the second bus connecting plate on the second flange; Be packaged with the first methyl vinyl silicone rubber insulating barrier on the conductor, bag is provided with the ground screen layer of semi-conducting material on the first methyl vinyl silicone rubber insulating barrier outer wall, is packaged with the second methyl vinyl silicone rubber insulating barrier on the outer wall of the ground screen layer of semi-conducting material.
The leading section of conductor, and between conductor and the first methyl vinyl silicone rubber insulating barrier, be folded with the first end screen of semi-conducting material; The rearward end of conductor, and between conductor and the first methyl vinyl silicone rubber insulating barrier, be folded with the second end screen of semi-conducting material.
Semi-conducting material is semi-conductive rubber or semiconductive silicone band etc.
First end screen and the second end screen are for to have the capacitance plate of all pressure effects so that this end of bus bars is axial and radial field is even.
Characteristics of the present utility model and advantage:
1, the isolated bus conductor is copper (aluminium) rod or copper (aluminium) pipe, end welded plate type terminal.
2, bus insulation is the solid insulation structure, solid insulating layer is the methyl vinyl silicone rubber insulation system, be respectively equipped with the capacitance plate of all pressing usefulness in the insulating barrier of the both ends of solid insulating layer, so that the isolated bus end axis is to even with radial field, insulating reliability is high.
3, be provided with the ground connection electric screen outside whole bus total length, ground connection electric screen outside is overcoat.
4, all insulation formula copper pipe bus adopts silicon rubber as main insulation, has basically eliminated extraneous moisture, dust and foreign object (such as mouse etc.) caused ground connection and phase fault, has the reliability of height.
5, the skin effect coefficient of copper pipe bus is low, and AC resistance is little, thereby the power loss of bus is little.Simultaneously, copper pipe bus is hollow conductor, and surface area is large, and conductive surface current density substep is even, and radiating condition is good.
6, owing to adopting silicon rubber as the structure of main insulation, the use of bus does not require circumstance of temperature difference, employing epoxy resin is arranged as the totally-enclosed bus of main insulation such as domestic, when low temperature because the metal material in the bus is different with the shrinkage ratio of epoxy resin, cause bus and external insulation layer to produce the gap, thereby affect bus quality and operational reliability.
7, bus shields with being provided with, and the people can contact, and has avoided the contact of animal and other factors and generation ground connection and short circuit phenomenon.
8, the isolated bus external insulation adopts silicon rubber as insulating material, and silicon rubber has UV resistant aging-resistant characteristic, can use indoor and outdoor, and product useful life is more than 50 years.
