Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.The explanation of following embodiment is only intended to help and understands this reality
With novel.It should be pointed out that, for those skilled in the art, in the premise without departing from this utility model principle
Under, it is also possible to this utility model is carried out some improvement and modification, and these improve and modification also falls into this utility model claim
Protection domain in.
As it is shown in figure 1, this system by upper support insulator 2, lower support insulator 1, electric heater unit, seal fan,
Seal fan pipeline 3, valve and control instrument composition.
As in figure 2 it is shown, insulator insulator 10 outer wall of upper support insulator 2 is close to be disposed with a circle electrical heating sleeve pipe 9,
Use unidirectional current mode of heating, in order to improve the temperature of insulator insulator 10, prevent the flue gas flowed outward due to malleation from insulating
Meeting cold junction dew on sub-insulator 10 and cause electric conduction phenomena, this electrical heating sleeve pipe 9 can heat the sealing outside insulator insulator 10 simultaneously
Wind, it is ensured that being dried within insulator insulator 10, prevents creepage.
Having 2-6 aperture in insulator insulator 10 top layout, sealing air is internal hence into insulator insulator 10.Sealing air
Pressurize through seal fan so that it is the big 1000-2000Pa of flue gas pressures in pressure wetter electricity cone section, it is possible to flue gas is suppressed
Do not enter in insulator insulator 10 in wet electricity cone section, play sealing effectiveness, but owing to sealing air enters insulation through aperture
After in sub-insulator 10, air-flow is disperseed, and sealing effectiveness is the best, then arranges near the local of top in insulator insulator 10
There is a piece of sealing air catch 7, sealing air is played guide functions so that it is flow to insulator insulator 10 inwall, insulate with tailing edge
Sub-insulator 10 inwall flows, and forms a gas hood sealing effectiveness, improves the sealing effectiveness of sealing air, can protect insulator simultaneously
Insulator 10 is not destroyed by condensation.Sealing air catch 7 is welded on wall bushing 8, rounded, and its edge is far from insulator
Distance d of insulator 10 internal face is 50-100mm, is that insulator insulator 10 is whole from insulator insulator 10 inside top surface distance l
The 1/4 to 1/3 of height.
As it is shown on figure 3, lower support insulator 1 is provided with two sealing air imports, one is inner joint 11, and one is external tapping
12.After seal fan pressurizes, the interior sealing air entered from inner joint 11, it is introduced into heating chamber；Heating chamber is configured with electricity
Heating ring 13, uses unidirectional current heating, different according to the power of electrical heating ring 13 and the initial temperature of sealing air, interior sealing air
70-120 DEG C can be heated to；4-8 aperture is had, interior close after heating on dividing plate between heating chamber and insulator insulator 10
It is internal that Feng Fengjing aperture enters lower support insulator 1；The pressure of interior sealing air is big compared with the flue gas in wet electricity snout
1000-2000Pa, can effectively prevent flue gas from outflowing, and plays sealing effectiveness, and the high temperature of interior sealing air can make insulator insulator
Keep in 10 being dried, stop the generation of creepage phenomenon.
Lower support insulator 1 has been separated out an annular region by dust cover 14, enters from external tapping 12 after the pressurization of sealed blower fan
The external seal wind entered can enter this annular region.Owing to this annular region volume is little, external seal wind can increase by flow velocity after entering, and adds
Speed pours in wet electricity snout, forms a gas curtain, kept apart by major part flue gas, subtract as far as possible outside dust cover 14
The probability that few flue gas flows in bottom support insulator 1, strengthens sealing effectiveness.
It is disposed with Pressure gauge and pressure transmitter on the spot on the sealing air pipeline of sealing system, sealing air pipe can be checked with far-end on the spot
The pressure in road, can check according to force value whether pipeline blocks or blower fan whether fault in real time.On pipeline, it is disposed with one simultaneously
Road backup line, accesses wet electricity body seal fan, when seal fan fault, can open the valve of this backup line, by wet
Electricity body seal fan carries out air feed to pre-arcing sealing system, it is ensured that run safety.
