Description
Technical field
The utility model is related to dual-power transfer switch technical field, more specifically to a kind of plug-in insulating part
And utilize the dual power supply of the insulating part.
Background technology
In electric power system, some are important or have place compared with particular/special requirement, and such as hospital, bank, important office, fire-fighting are set
Apply, skyscraper etc., do not allow interruptedly supplying power.And in order to ensure uninterrupted, continuous power supply, above-mentioned place typically all can be using double
Power supply is powered, and when normal power source breaks down or during accident power-off, can be switched to stand-by power supply and be powered.Double power-supply automatic transferring
Switch for, when main electricity breaks down, being both avoided that trouble power powered to the load in electric power system, and can be reliable
The qualified normal operation of power supply input is selected, to ensure that power supply is uninterrupted.Extensively should thus it be obtained in places such as hospital, banks
With.
In the design process of dual-power transfer switch, manufacturer it is universal it may be noted that a problem be exactly：Must
Dual-power transfer switch is avoided to enter electrical connection row, go out the string arc phenomenon of appearance between phase and phase of electrical connection row, because dual power supply is cut
Change and there is high current in the phase of switch, electric arc is easily produced between phase, once going here and there arc between there is phase, easily cause electricity
Short out road, causes Circuit Interrupt road device, load etc. to damage.And the side for avoiding the occurrence of string arc phenomenon generally used in the prior art
Case is in the setting flash barrier between phase and phase for entering electrical connection row, going out electrical connection row, such as China Patent No.
ZL201020134467.2, authorized announcement date is on December 22nd, 2010, and invention and created name is：A kind of dual power supply switching is opened
Close；This application case is that the flash barrier that material is expoxy glass is set between tetra- phases of R, S, T and N, so as to eliminate phase and phase
Between arcing, climb electricity and phase fault phenomenon, prevent direct body contact from getting an electric shock, ensure safety.
It is strictly a kind of effective scheme for avoiding going here and there between phase arc to set flash barrier, but is changed for dual power supply
Switch, because it will typically at least set two-way inlet wire, all the way outlet, and general two-way enters electrical connection row and is arranged at dual power supply
Side, goes out electrical connection row and is arranged at dual power supply opposite side all the way, or enters electrical connection row all the way and go out electrical connection row's setting all the way
In dual power supply side, the string arch problem that electrical connection row is arranged between dual power supply opposite side, adjacent two-way line bank is entered on another road
Enough attention are not obtained.There is manufacturer by increasing the distance between adjacent two-way line bank, it is ensured that adjacent two-way
Have enough electric clearances between line bank, come solve to go here and there between line bank arc the problem of, but this will certainly increase dual power supply again
Volume, increase dual power supply manufacturing cost.
Through retrieval, Chinese Patent Application No. 201520728830.6, the applying date is September in 2015 18, innovation and creation name
Referred to as：Rotation high-voltage dual power disconnecting switch, this application in a kind of double isolated bits of the indoor Double Pole Double Throw with annular insulating boot
Case includes：It is fixed on the outside of A, B, C three phase isolated support, the insulating support in mounting bracket, inside insulating support
For cylindrical hollow configuration, insulating support inside is provided with upper acting arm, lower acting arm, and the upper acting arm, lower acting arm are installed
In swing arm fixed seat, the swing arm fixed seat is linked together by the full skirt that insulate, and constitutes operation axis, and operation axis is also pacified
In mounting bracket.This application case by setting insulation full skirt between A, B, C three-phase swing arm fixed seat and mounting bracket, plus
Insulation creep distance greatly between mounting bracket, between phase, makes each functional unit block, and compact conformation reduces equipment volume.
But above-mentioned application case complex structural designs, are not easy to popularization and application.
