transformers pressure impregnation machine ,
vacuum varnish impregnation machine
1. Application
1.1 The impregnation equipment VPI is the key equipment for
insulation treatment of
high voltage motors, special anti-explosion motors, and
transformers. The vacuum
impregnating treatment enhances the mechanical strength,
insulation, anti-moisture
and anti-mold performance of the windings.
1.2 The installation type for the resin storage tank and the motor
vacuum impregnation
equipment is vertical type.

|
3.2 Resin Storage Tank
insulation resin/varnish storage tank:Φ1000×1000mm, 1 piece; installation type: vertical; material for head: Q235-B; material for tank body: Q235-B; flange: Q235-B forging parts; working vacuum: 5000-10000Pa; The resin storage tank is designed
with one peephole light and 1-2 observation windows. Mixing speed: 25-36r/min. Motor power: 1.1KW. 100mm jacket layer. |
3.3 Vacuum System
1 set of 2X-30 rotary vane pump max air suction speed: 30L/S; motor power: 3KW. |
3.4 Hydraulic system
3.5 Resin Supply and Returning System, 1 set
3.6 Pneumatic System, 1 set
Working pressure: 0.4-0.7Mpa.
3.7 Heating system
The motor winding impregnation plant is equipped with the heating
system. It is comprised of the electrical heater, the temperature
sensor, valves, and the pressure gauge. Heater power: 15kw. The heater heats the circulation water
circulating in the jacket layer. This system is used to keep the resin liquid within a certain
temperature range. The temperature is equipped with the automatic controller. There is
also one overtemperature alarm. When the actual temperature exceeds
the limit valve, the heater stops heating. |
3.8 Chilling System
chilling machine, 1 set; power: 10Hp, 400V; refrigerating capacity:
25000W/H; cold water flow rate: 3M3/h. This system is comprised of the cold water tank, the pipe pump, the
pressure gauge, the expansion tank, the valves, and the pipes. This system for the transformer pressure impregnation machine is
used to cool the varnish storage tank and the condenser. This system is used to cool the varnish. The heating system is in
parallel connection with the chilling system. The ON/OFF and fault of the chilling system is shown on the touch
screen. And there is an automatic alarm on the touch screen when
fault occurs. |
3.9 control system, 1 set
3.9.1 control cabinet, 1 piece ( plastic-spraying coating);
voltage: 400V, 3 phase, 50HZ;
220V, 1 phase;
3.9.2 PLC control and industrial computer control system ( both
auto and manual available);
PLC brand: Mitsubishi PLC;
3.9.3 industrial computer with 21 inch liquid
display (search and printing of vacuum degree, pressure, and resin
level);
3.9.4 mouse operation.
3.9.5 remote control level indicator.
3.9.6 Real-time recording and printing of product number and
technical parameters, parameter
curves, process physical parameters: vacuum degree - time, pressure
- time, and resin level - time.
3.9.7 It can automatically collect and record vacuum and pressure,
and has memory function.
3.9.8 The control system for the vacuum varnish impregnation
machine can display the vacuum
degree, pressure and other parameters measured, indicating the
whole processing process.
3.10 Installation material, 1 set
seamless steel pipe, 1 set; standard flanges, and elbows; various bolts; |
4.Installation and Commissioning Service
The vacuum impregnation of electrical windings is installed on the
base plate and installed as
a whole.
The machine is already tested before delivery. After the equipment
arrives at the customer's site,
it can work only by connecting to the power supply.
