Description
Technical field
The present invention relates to electrical equipment and electrical engineering field, in particular it relates to a kind of compressed air purifier and from
The ventilation protection device of cold type enclosed busbar.
Background technology
In order to carry out electric power transmission, the connection bus that large and medium generator group is exported between main transformer typically uses gold
Belong to enclosed busbar.It is known that enclosed busbar can be affected by the ambient, such as, change or special gas in service condition
Wait change in the case of, the air of external humidification can invade inside bus, cause bus-bars conductor, supports insulative son, shell interior
Condense on surface and disk insulator, thus reduce the insulating properties of bus.Additionally, enclosed busbar itself is due to poorly sealed,
The external world can invade bus containing dust, the air of impurity or thick fog and chemical gases, causes the insulation resistance of insulator to decline,
Easily cause enclosed busbar generation arcing fault.
In order to prevent humid air from entering enclosed busbar, up-to-date enclosed busbar typically uses pressure-fired to design so that envelope
Close the air pressure in bus and be more than external pressure, thus prevent external humidification air from entering inside bus.But, setting earlier
Meter and the self-cooled enclosed busbar produced, do not use pressure-fired design, therefore cause enclosed busbar to be exhaled in running
Suction phenomenon is serious, it may appear that enclosed busbar internal laying dust, condensation, thus causes flashover fault.
In order to solve the problem existing for the self-cooled enclosed busbar producing earlier and designing, currently mainly use with
Lower device:
Hot-air maintenance device: hot-air maintenance device may be used for removing the tide within enclosed busbar before generating set starts
Gas, improves the temperature within enclosed busbar and the saturated water capacity of air.Hot blast is protected care device and is used centrifugal high pressure fan to inhale
Enter air, after filtering, pressurizeing, use electric heater unit heating, improve the saturated water capacity of air and send into enclosed busbar
Inside, is then discharged by enclosed busbar air outlet.This hot-air maintenance device utilizes the physical property after air heating, prevents mother
Occur condensation and moisture to assemble in line, but it is only capable of improving the solid insulation within enclosed busbar, it is impossible to improve inside bus
The aridity of air.Therefore, in the case of using hot-air maintenance device, due to ambient temperature and the change of generating set load
Changing, enclosed busbar still may condensation.Water such as, when bus length is longer, in hot spot farther out bus inner air
Regelation is become aqueous water by steam, causes bus section insulation defective.
Electric heater: electric heater is arranged near the insulator within enclosed busbar, to maintain within enclosed busbar
Air themperature, it is to avoid during Unit Commitment, enclosed busbar inner air excessive temperature differentials causes condensation.In maintaining enclosed busbar
The temperature in portion, needs to install multiple heater, thus reduces the sealing property of enclosed busbar, and running wastage is big.Equally
Ground, electric heater only reduces relative humidity by the air themperature within raising enclosed busbar, can not improve inside bus
The aridity of air.It addition, electric heater may come off in running, can cause and put between enclosed busbar conductor and shell
Electricity.
Air blast cooling device: in the case of generating set capacity is relatively big, needs to use the type of cooling of air blast cooling, and
In the case of generating set capacity is less, typically take the type of cooling of natural cooling.Using air blast cooling, enclosed busbar is led
The current-carrying capacity of body can increase 0.5-1 times, and conductor and shell, the external diameter etc. of enclosed busbar greatly reduce, thus save and substantial amounts of have
Non-ferrous metal and convenient construction are installed.But owing to adding blower fan, cooler, filter ion unit, add running cost and safeguard work
Measure.For need not be significantly increased the self-cooled enclosed busbar of current-carrying capacity, if using the type of cooling of air blast cooling, change
Make work complexity, investment amount greatly, and the layout of equipment is also required to bigger area.It should be noted that self-cooled closes mother
Line refers to use the type of cooling of natural cooling to carry out the enclosed busbar cooled down.
For self-cooled enclosed busbar, no matter use which kind of mode above-mentioned the most not ideal enough, it is necessary to it is cold that exploitation makes new advances
But mode.
