Transformer core should be tested regularly dielectric strength (test method and requirements for the same coil), found that dielectric strength lower than the standard, to be replaced on the core bolt or bushing insulate.
A connection point between <br> <br> bad wire coil terminals inside the coil and lead to high, the low pressure of the porcelain bushing contacts and the contacts of the tap, such as poor contact will produce local overheating, coil insulation damage, A short circuit or open circuit occurred.
. Poor oily, too little oil <br> <br> transformer insulating oil after the water accidentally, oil and other impurities or other mixed with oil during storage, transport or operation and maintenance, will significantly reduce the dielectric strength . A short circuit occurs when the dielectric strength drops to a certain value. Thus a longer standing time put into operation before the insulating oil must be carried out tests, such as moisture, impurities, viscosity, breakdown strength, dielectric loss angle, permittivity other items. During operation, the oil quality should also be tested regularly. When problems are found, appropriate measures should be taken in time.
PRODUCT NAME:Aluminum Phosphate, Aluminum Metaphosphate ,Potassium Silicate Curing Agent,Aluminum Phosphate Crystal
PRODUCT TYPE:High Temperature Materials, Binder
PRODUCT APPEARANCE:White Powder
CHEMICAL CLASS:AlPO4
CAS No．:7784-30-7.
PRODUCT APPLICATION:It can solidify potassium silicate (other name: potassium water glass) at room temperature. It is mostly used as binder and curing agent in the production of Hi-Temp Refractory Materials for kiln. It also serves as fluxing agent in the production of special glass, as binder in fabrication of ceramics or tooth, and so on.
Aluminum phosphate adhesive has excellent heat-resistance and weather-resistance, not only a widely used adhesive in refractories, it`s also an importantingredient in inorganic coatings(such as powder coating). It also used in the production of siliceous,high-aluminum,magnesian,siliconcarbide and oxides of concrete.
