Description
Technical field
The present invention relates to a kind of reactor with T-shaped core insulation against ground restorative procedure, further relate to use the dress of the method
Put.
Background technology
Reactor with T-shaped core have office put little, mechanical strength is high, volume is little, fire-retardant, safeguard less, leakage field little,
The advantage being suitable for indoor location, is widely used in the fields such as power transmission and transformation system, electric railway, metallurgy, particularly
Installing space finite sum has the net place such as transformer station and underground substation, city of special fire protection requirement, more can be abundant
Play the superiority that its volume is little, fire-retardant.Carry out pressure test examination at reactor with T-shaped core or put into operation
Before, owing to indoor environment or the underground space are moister, under the insulating resistance value meeting substantially of reactor with T-shaped core
Fall, sometimes every 1000V rated voltage, its insulating resistance value is less than 2M Ω, and the insulation of reactor with T-shaped core
It is that insulation against ground resistance value is not less than 2M Ω that resistance value runs minimum requirements.Even more serious situation is, reactor
When suffering abnormal moist generation dew condensation phenomenon, insulation resistance also can level off to zero.
In order to repair reactor with T-shaped core insulation against ground, the most generally employing following two method:
A kind of method is to transfer in special heating furnace by whole reactor, according to certain heating curve to electricity
Anti-device heat temperature raising, makes the moisture in insulant evaporated.The defect of the method is: (1) need lifting to turn
The special equipments such as fortune, heating furnace, and need to heat whole reactor, heating does not has selectivity, consumes more
Energy；(2) transfer reactance device process is longer, and heating curve includes that several constant temperature keeps period, accumulating time
12 hours or more than, cause repairing efficiency long.
Another kind of method is to check and accept at reactor or install scene in place, utilizes heat radiation principle of heating, will heating
Device or high-power heating lamp tube are arranged in around reactor, after energising, reactor are carried out Baking out, to drive away
Moisture in insulant.The method has the disadvantages that (1) every reactor need to use 6～10 power to be
The warmer of about 1000W or high-power heating lamp tube, total heating power is high；(2) the environment residing for reactor
Space is relatively big, and heat is low to the directional heat conversion efficiency of reactor from warmer or high-power heating lamp tube, reactance
Device heats up slow, and effect is poor；(3) heating process needs personnel's carefulness to follow the tracks of, and carries out safety measure, with fire-proof,
Cause the more manpower of consuming.
Summary of the invention
