Description
Technical field
The utility model relates to a kind of silicon rubber high voltage bus, and in particular a kind of silicon bi-layer rubber is to crowded head.
Background technology
In the connection of electric substation's high voltage distribution installation, and the connection of the electrical equipment such as transformer and corresponding power distribution equipment, mostly adopt bare conductor or the twisted wire of rectangle or circular cross-section, this is referred to as bus.The effect of bus collects, distributes and transmit electric energy.Because bus is in operation, there is huge electric energy to pass through, during short circuit, subject very large heating and dynamo-electric effect, therefore, must reasonably select bus material, cross sectional shape and sectional area to meet the requirement of safety and economic operation.Bus is divided into hard bus and soft bus by structure.Hard bus is divided into again rectangular bus bar and tubular bus.Rectangular bus bar is generally used in main transformer in switchgear house, and its advantage is construction install convenience, changes little in operation, and current-carrying capacity is large, but cost is higher.Soft bus is used for outdoor, and because space is large, wire swings to some extent to be also unlikely and causes wire spacing inadequate.Soft bus construction is easy, cheap.
Silicon rubber refers to that main chain is alternately made up of silicon and oxygen atom, silicon atom is connected with usually the rubber of two organic groups.Common silicon rubber is primarily of the silica chain link composition containing methyl and a small amount of vinyl.The introducing of phenyl can improve the high-and low-temperature resistance performance of silicon rubber, and the introducing of trifluoro propyl and cyano group then can improve heatproof and the oil resistance of silicon rubber.Silicon rubber resistance to low temperature is good, generally endure at-55 DEG C.After introducing phenyl, can-73 DEG C be reached.The heat resistance of silicon rubber is also very outstanding, can long-term work at 180 DEG C, a little higher than 200 DEG C also can bear several weeks or the longer time still flexible, instantaneous can the high temperature of resistance to more than 300 DEG C.The good permeability of silicon rubber, OTR oxygen transmission rate is the highest in synthetic polymer.
The excellent electric properties of silastic material, hydrophobicity is good, resistance to electricity.And can react from merging ground the insulating barrier forming silicon rubber integration, the resistance to ability punctured is given prominence to, and is the more new material of transformer station's insulating protection.
The coated of simple silastic material can use winding to realize, but for requiring thicker silastic-layer, simple coated very difficult realization.
