Description
Technical field
The utility model is related to a kind of enclosed busbar, especially a kind of novel electricity generator enclosed busbar device.
Background technology
In power plant electrical system, generally use is closed between station service transformer and 6kV/10kV Medium Voltage Switchgears
Busbar connects, and enclosed busbar has the advantages that safety, easily arrangement, easy care relative to open type busbar, but when big light maintenance is met by power plant
Or failure cause generator to be shut down for a long time after when restarting, in terms of enclosed busbar sealing performance and weather due to, station-service
The enclosed busbar dielectric level that encounters relatively low problem when electric system is restored is each Coastal Thermal Power Plant of long-standing problem, especially
It is located in the common difficulty of moist rainy foggy southern Coastal Thermal Power Plant.
To find out its cause, generating the above problem mainly since bus temperature is 75-83 DEG C when unit operation, shell temperature
Degree is 56-65 DEG C, and when compressor emergency shutdown, busbar and skin temperature rapid decrease, the saturation of air is containing wet between busbar and shell
Maximum value when measuring by normal operation declines rapidly, leads to have liquid water precipitation between busbar and shell, and water is precipitated in these can be serious
The insulation destroyed between busbar and shell is easy to happen enclosed busbar conductor flashover over the ground when being switched on again, especially with high salt
It is easier to occur when the strand weather of mist high humility.
For solve the problems, such as busbar make moist insulation it is low, at present widespread practice be installation enclosed busbar inflation dehumidification device,
Its mode is to lead to hot wind in the female shell of envelope, and the hot wind being passed through can drive away a part of humid air, moreover it is possible to improve the saturation of air
Moisture content values reduce relative humidity, enclosed busbar dielectric level are made to improve quickly.But since busbar and shell are aluminum,
Heat-transfer effect is good, and heat dissipation is also fast, thus once stop heating or away from hot spot farther out when, it may appear that the case where very fast temperature drop, cause
It needs to input hot gas in shell for a long time in drying, energy consumption is larger.
