Vacuum units for transformers is special equipment used to remove air from transformer tank. It also absorbs surface moisture and gas of transformer active part, improving its insulation performance. All 150-750 kV voltage transformers \u00a0are subjected to vacuuming dehydration.<\/p>\n
Prior to vacuum process – a tank should go through a leakage test: a vacuum not lower than 1000 hPa is created and maintained in the tank for one hour. After that a residual pressure is measured.<\/p>\n
When the air has been evacuated and a transformer reached a perfect vacuum state acceptable for a particular transformer. \u00a0The oil with vacuum is fed into a vacuum unit.<\/p>\n
GlobeCore<\/i><\/b> developed BV vacuum unit for transformers<\/a> that creates negative pressure in transformer tanks and drying electrical equipment. \u00a0\u00a0They are also successfully used in conjunction with degassing equipment.<\/p>\n GlobeCore<\/i><\/b> vacuum units for transformers are two-stage vacuum systems consisting of vacuum and fore-vacuum pumps. \u00a0The fore-vacuum pump is necessary for obtaining initial vacuum. \u00a0The vacuum pump creates perfect vacuum. \u00a0This combination allows to achieve a high performance of up to 2100 m3\/h.<\/p>\n","protected":false},"excerpt":{"rendered":" Vacuum units for transformers is special equipment used to remove air from transformer tank.
