The corresponding position of blower is in Openworks shape；There are horizontally disposed fixed orifice plate, the cabinets cavity above fixed orifice plate above blower
For thermal insulation barn, there is open and close door in the corresponding cabinet side of thermal insulation barn, and the thermal insulation barn is for installing turbine generator stator bar.Right
During the stator bar of hydrogenerator carries out thermal cycling test, need to drop stator bar when completing heating step
Wen Shi, the outer chamber of the temperature (generally 150 DEG C) and cabinet inside holding storehouse of stator bar air themperature (it is close with room temperature,
Generally at 30 DEG C or so) it differs greatly, it only needs to open blower at this time, cold air is imported into thermal insulation barn through fixed orifice plate
Cooling down is carried out to stator bar.When cool down a period of time after, the temperature (such as 40 ~ 50 DEG C) and air themperature of stator bar
(30 DEG C or so) difference becomes smaller, and when cooling rate is slack-off, can open evaporator to the air cooling of process, then will be made by blower
Cold air imports thermal insulation barn through fixed orifice plate, and it is cooling to continue fast cooling to stator bar.Uniform cloth in fixed orifice plate
The through-hole set can equably cool down stator bar, guarantee the consistency of all stator bar cooling change conditions.Together
When, opening evaporator in due course may make stator bar to remain the state of fast cooling, it is ensured that stator before the deadline
Bar is cooled to specified temperature, the accurate and effective of guarantee test result.
Further, removable orifice plate is set in fixed orifice plate, and controls removable orifice plate with the stomata on vertical partition
It moves left and right, the size of adjustable strip venthole, adjusts ventilatory capacity, reach the mesh of control stator bar rate of temperature fall
's.
Further, the pressure sensor of wall box setting can detect the intracorporal air pressure change of case, be conducive to adjust
The revolving speed of blower keeps the intracorporal wind pressure of case more stable.
