Degassing block 1 – is hermetic cylindrical vessel, on the top of whicht here are neck for oil filling with hermetic cover, 2 ball valves, vacuum meter (-1…0 kgf/cm2).
Valve K2 via collet connection, flexibly pipe and valve K1 is connected with vacuum pump. There is a silenceron valve K3.
Block of topping-up – is pneumatic cylinder with piston D 160mm. The block is constructed for oil taking from degassing block and delivering of dosed oil in bushing of the transformers.
Piston rotation is made via screw pair by means of wheel by hand. In the bottom of cylinder there is an oil dispensing unit, which consists of piping, ball valve and manometer vacuum gauge (- 1…0…9 kgf/cm2).
Block of topping-up – its quick- release and is connected to base withs pecial screws.
The design prevents contact of degassed oil with atmosphere air.
The filling of topping-up block with degassed oil and creativon pressure for topping-up of bushes is made with wheel rotation by hand. Topping-up of bushes is made from earth, length of pipe is not less than 7 meters.
Vacuum pump 3 (sliding vane rotary pump 50810-235) is designed for evacuation in degassin gblock. A pump drive is from engine of single-phase power supply unit 220 V. Intake pipe of pumph as a 3 –way valve K1,handle o fwhich has 2 positions:
- Valve connects vacuum pump with degassing block.
- Valve connects vacuum pump with atmosphere (for letting-to-air in pump chamber under pumps witching off). Operation principles of vacuum pump 50810-235 is set forth in section II of appendix B.
Control is von vacuum pump, model 50810-235.
This plant comes complete with the set of spare parts sufficient for trouble free operation
During 1 years period.
