Vacuum Type Transformer Coil Drying Oven
Description of vacuum type transformer coil drying oven:
This kind of variable-pressure vacuum drying furnace adopts variable-pressure drying principle suggested by Dr. Moll from Germany, specialized for drying transformer bodies. Comparing to conventional vacuum hot air cycling method, drying cycle of this variable-pressure type has been saved about 30-45%.

Main features of variable-pressure vacuum type transformer coil drying oven:
1) Compact structure, small occupation
2) Heating system is controlled by power control module, assuring even and stable temperature; Real power consumption during temperature-keeping is only about 35% of total power;There is no fluctuation of heating load and thus reduces actual heating power very much.
3) Extreme high vacuity, less than 30Pa under cold condition
4) PLC control, more stable and reliable
5) Special baffle valves for vacuum drying, better vacuuming performance

Main use of equipment
The equipment is used for the drying treatment of electrician products of oil-immersed power transformers with voltage levels below 110KV. We guarantee the process requirements and quality requirements of product processing, and provide process treatment schemes of 35KV and 10KV voltage levels and related control program.
Main technical features of the equipment
This equipment has the following technical features:
1 With reasonable vacuum system design, there is enough condensed water in the condenser to effectively avoid the pollution of the vacuum pump during the drying process, which greatly prolongs the service life of the vacuum pump.
2 The heating system control is equipped with a power control module to ensure smooth temperature control, reduce the actual heating power during heating, and prolong the service life of the heating tube.
3 In the heating process, according to the different temperature of the body, the pressure alternating mode is automatically repeated several times to periodically reduce the pressure in the vacuum tank to a certain value, so it can create the most suitable conditions for the evaporation of water in the insulation of the body, it make the water evaporation process of drying process in a reasonable state.
4 The processing time of the equipment for the 110KV grade 63000KVA product can be controlled within 70-80 hours, which can save more than 30% compared with the traditional hot air drying equipment.
5 The equipment is adjusted by variable pressure, which can effectively solve the the iron core rust problem during the drying process.
6 The equipment automation level and the products processing technology level both can reach the domestic advanced level, and the quality of the processed products can reach the level of superior products in the industry.
7 This equipment adopts manual control and automatic control. When it is automatically controlled, it can realize unattended automatic drying of the whole drying process.
