The direct current transportation of point has become the trend of electric power industry development.In high pressure, ultrahigh-voltage alternating-current transmission of electricity, the dish type of existing production is outstanding
Hanging tempered glass steel insulator has been widely used, but this dish type suspension type tempered glass steel insulator cannot be straight
It scoops out and is used in super high voltage direct current electricity transmission, this is because dish type suspension type tempered glass steel insulator is defeated applied to superhigh voltage DC
There is also have following point in electricity: first is that DC line electric current is different from AC line current, it is defeated in direct current under DC electric field
One Direction Transfer and the local ion aggregation that ion can occur during electricity operation inside toughened glass insulator, to cause tempering
The aging of glass insulator；Second is that being effectively improved under heavy pollution to reduce a possibility that toughened glass insulator is by air breakdown
The flashover voltage and breakdown voltage of toughened glass insulator, DC circuit move the volume resistance and ion of toughened glass insulator
Shifting rate requires high than volume resistance and ionic mobility of the alternating current circuit to toughened glass insulator；It is tempering in DC circuit again
The steel feet of glass insulator cement interface than steel feet in alternating current circuit cement interface be easier corrode, make steel feet and
The mechanical strength of toughened glass insulator reduces.And the insulator of on-line operation, in the natural environment by sulfur dioxide, nitrogen
The influence of the atmospheric environments such as oxide and graininess dust gradually deposited one layer of dunghill on its surface.In dry weather
In the case where, these surfaces can be worked normally with the insulator of dunghill, but when encountering the wet weathers such as mist, dew, rain,
Pollution severity of insulators object absorbs moisture, makes electrolyte dissolution in pollution layer, ionization, eventually leads to flashover.
Because the invention one kind can with direct current and seem with the laminated toughened glass insulator of fine antifouling work ability
It is particularly important.

Or low Pyrex layer；The chapeau de fer is set on the lug boss on vitreum top, and the steel feet is arranged in vitreum full skirt
In the inner hole of heart bottom；Between chapeau de fer and the lug boss of vitreum and between the inner hole at the full skirt center of steel feet and vitreum
It is bonded by one layer of cement glue, chapeau de fer and steel feet is firmly combined together with vitreum.
The middle layer DC toughened glass thickness 6-7mm.
The outer casing aluminosilicate glass or low Pyrex thickness degree 0.6-0.8mm.
Titanium dioxide coating layer on the glass external surface.
Zinc oxide coating is coated in the outer surface of chapeau de fer.
Zinc oxide coating is coated in the outer surface of steel feet.
Locking pin is equipped in the centre bore of chapeau de fer.
The utility model the utility model has the advantages that
(1) vitreum central core is different from surrounding layer material in the utility model insulator, and the coefficient of expansion is also different, cold
When but, surrounding layer is first shunk, and will form pressure to central core naturally, it is made to generate prestressing force, thus achieve the purpose that tempering,
Its effect is better than common air hardening steel effect, and the uniformity of tempering is fine, can avoid glass insulator and reveals phenomenon.General steel
Change glass insulator compression in 100~140MPa, the compression of the utility model glass insulator up to 250~350MPa,
More resistant to external force collision, phenomena such as not easily causing unfilled corner, rupture, cracking is not generated；The resistance to temperature difference is greater than 150 DEG C, permanent open air use
It still becomes clear as new, the hard careful no pore in surface is easily self-cleaning, and intensity is high, has to the normal operation for guaranteeing electric system
Significance.
(2) vitreum has included boron oxide and aluminium oxide, titanium dioxide coating on outer surface in the utility model insulator
Layer makes the utility model insulator with very high mechanical strength and there is good anti-pollution to dodge ability.
(3) in the utility model insulator in vitreum titanium dioxide layer sterilizing ability cooperation lithia inhibit sodium from
The One Direction Transfer and localized clusters that son, potassium oxide and sodium oxide molybdena occur under DC electric field long term improve volume resistivity,
Delay the aging of vitreum and fails and can be used in direct current.
(4) the utility model insulator cap and the coating of steel feet outer surface are coated with the Zinc oxide coating of high temperature process, mention
High chapeau de fer and steel feet anti-electrocorrosion, extend the service life of chapeau de fer and steel feet.
