Description
Technical field
The utility model relates to double-purpose electric installations for electrical domain.
Background technique
For dual power supply electric substations multiple for user, some electric substation easily occurs to cause to use since higher level substation has a power failure
The case where family electric substation power loss, such as: certain user has dual power supply electric substation A and B, and wherein two telegram in reply sources of A electric substation come from one
A higher level substation M, two telegram in reply sources of B electric substation are from higher level's power supply substation M, N.And two customer substations of A, B share
One telegram in reply source.
At power supply station when M whole station power loss, it will lead to customer substation A whole station power loss, influence to produce.
Summary of the invention
The technical problem to be solved by the utility model is to how to solve powerup issue present in background technique.
The technical scheme adopted by the utility model is a kind of power supply circuit, including the first power device 6, the second electricity consumption
Device 7, for the first power device 6 by the first electric substation as main power supply, the first power device 6 passes through one group of work of the second electric substation
For available electricity, the second power device 7 passes through one group of the second electric substation as main power supply, and the second power device 7 passes through the second power transformation
Two groups of institute is equipped with first switch 1 as available electricity on the route between the first power device 6 and the first electric substation, first uses
Second switch 5, the second power device 7 and the second electric substation are installed on the route between one group of electric installation 6 and the second electric substation
Third switch 4 is installed on the route between one group, is installed on the route between two groups of the second power device 7 and the second electric substation
There is the 4th switch 3, is installed on the first power device 6 and the public bus of one group of the second electric substation of the second power device 7 connection
5th switch 2 installs the contact branch of one article of the 6th switch 8 of point additional, gets in touch with one end connection second switch 5 and the 5th switch of branch
Route between 2 gets in touch with the route between the other end connection first switch 1 of branch and the first power device 6.
The beneficial effects of the utility model are: only needing a contact branch just in the case where supply network pattern is constant
The active and standby power supply that can be realized double-purpose electric installation will not influence double-purpose electric installation when any one power transformation problem occurring
Power supply.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein, 1, first switch, the 2, the 5th switch, the 3, the 4th switch, 4, third switch, 5, second switch, 6, first uses
Electric installation, the 7, second power device, the 8, the 6th switch.
Specific embodiment
As shown in Figure 1, (second uses four pumping plant of water supply of the 10kV of Shanxi Taigang Stainless Steel Co., Ltd's water process
Electric installation 7) and the water supply Switching Station (the first power device 6) of 10kV be dual power supply electric substation, wherein four pumping plant power transformations of supplying water
Two telegram in reply sources (main power source and stand-by power source) be all from the electricity generation system substation (the second electric substation) of a higher level 10kV,
The two telegram in reply sources (main power source and stand-by power source) of the water supply Switching Station electric substation of 10kV come from from first electric substation's another way all the way
Second electric substation.Supply water four pumping plants and water supply Switching Station shares the one group of power supply of the second electric substation.
In the April in 2017 of second electric substation's whole station power loss on the 11st, lead to the four pumping plant whole station power loss that supply water, entire company disappears
Waterproof interrupts supply, and many equipment face the danger of anhydrous fire fighting and rescue.
Water supply Switching Station to realize 10kV is needed to that can provide power supply to four pumping plants that supply water rapidly in two power devices
Between increase interconnection (contact branch).In view of two stop spacings are from remote, difficulty of construction is big for new route.After proving repeatedly,
It is as shown in Figure 1 following improvement has been gone out.
A kind of power supply circuit, including the first power device 6, the second power device 7, the first power device 6 become by first
Electricity be used as main power supply, and the first power device 6 is electric as available by one group of the second electric substation, and the second power device 7 passes through the
Two one group of electric substations are used as available electricity, the first power device for two groups by the second electric substation as main power supply, the second power device 7
6 and the first route between electric substation on first switch 1 is installed, between one group of the first power device 6 and the second electric substation
Second switch 5 is installed on route, third switch is installed on the route between one group of the second power device 7 and the second electric substation
4, the 4th switch 3 is installed on the route between two groups of the second power device 7 and the second electric substation, in 6 He of the first power device
Second power device 7, which connects, installs the 5th switch 2 on the public bus of one group of the second electric substation, install one article of the 6th switch 8 of point additional
Contact branch, get in touch with branch one end connection second switch 5 and the 5th switch 2 between route, get in touch with the other end of branch
Connect the route between first switch 1 and the first power device 6.
When whole power-off occurs for the second electric substation, the 5th switch 2, second switch 5, the 4th switch 3, closure the 6th are opened
Switch 8 realizes power supply of first electric substation to the second power device.
