Vapor Phase Oven For Transformer

Working principle under heating and vacuum condition liquid kerosene will become vapor in high temperature.

Vapor phase oven for transformer.

Generally there are three steps to the process. Processes for transformer drying which have eventually lead to vapor phase drying technology are hot air hot air with rough vacuum vacuum drying oven oil circulation oil spray vacuum pressure impregnation. The heating up phase the evacuation of the autoclave and cooling. Power transformers and shunt reactors proven history for future success duration.

The two methods only differ in the heating up phase hot air and vapor phase. The vapor phase process is the ideal solution to reflow temperature control issues in small batch production runs. Simple made home made vapor phase oven. Unlike ir or convection batch type ovens with varying temperature control concerns our vapor phase ovens provide you with evenly distributed temperature throughout the production cycle completely under your control.

Heating of insulation materials under vacuum reduced oxygen levels minimize oxidation and thermal aging of cellulose materials resulting in less loss of life than can be achieved in rapid oven drying or radiation processes. The imdes mini condens it is a small vapour phase soldering furnace suitable for pcb s with maximum dimensions of 240 x 170 x 20 mm. In contrast with the convection reflow oven the vapor phase reflow oven has a much smaller footprint and the pcb assembly moves vertically up and down instead of sideways.

Many advantages exist by using a vapor phase process in the manufacture of power transformers. 3l becher pyrex heater cheap chinese like and an optional thermocouple reader. 2 1 hot air hot air with a maximum temperature of 120oc is used for heating up the active parts of the transformer. In addition all imdes vapour phase furnaces are equipped with a profiler function with which temperature profiles can be set.

Unlike convection this type of ovens uses condensation or vapor phase for soldering. The mini has an output of 1000 watt and has a cycle time of 10 minutes. Kerosene vapor phase drying equipment kvpd is mainly suitable for drying transformer bodies in super high voltage than 110kv and big capacity. The vapor comes from boiling perfluoropolyether an inert heat transfer liquid.

Reducing the pressure leads to a lower boiling point which causes the dissolved water in the transformer s active part to vaporize.
