Female voltage transformer.
It is provided with two data transmission between described low week protection voltage switching device P and low all protection devices W
Passage.
Compared with prior art, this intelligent substation protection of low week SV sampling link can ensure that at only one
In the case of the busbar voltage combining unit of normal work, low all protection devices still are able to run normally, simultaneously
The voltage sample data of a certain section of bus can also be moved back according to the individually throwing that needs of actual motion.
Accompanying drawing explanation
Fig. 1 is existing low week protection voltage data sampling chain graph.
Intelligent substation protection of the low week SV sampling link schematic diagram that Fig. 2 provides for this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described further by specific embodiment, but following embodiment is exhausted
Non-have any restriction to this utility model.
As in figure 2 it is shown, this intelligent substation low week protection SV sampling link include mother's n voltage transformer pt 1,
Mother's m voltage transformer pt 2, bus combining unit A, bus combining unit B, low all protection devices W, institute
It is additionally provided with low week protection between bus combining unit A, bus combining unit B and low all protection devices W stated
Voltage switching device P；Input termination mother's n voltage transformer pt 1 of bus combining unit A and mother's m voltage
Transformer PT2；The input of output termination protection of the low week voltage switching device P of bus combining unit A；Female
Input termination mother's n voltage transformer pt 1 of line combining unit B and mother's m voltage transformer pt 2；Bus closes
And the input of output termination protection of the low week voltage switching device P of unit B；Low week protection voltage switching device
Output termination low week protection device W of P.

Passage.
The implementation of intelligent substation protection of the low week SV sampling link that this utility model provides is as follows:
If when n=4, m=5, bus combining unit A, bus combining unit B all gather from 4 female voltages mutual
Sensor PT1, the data of 5 female voltage transformer pts 2, and transfer data to low week protection voltage switching device
P, the lowest week protection voltage switching device P have pressure and automatic two kinds of mode of operations；
Under compulsory mode, low week protection voltage switching device P can force to gather bus according to being manually specified
Combining unit A or the data of bus combining unit B；
In automatic mode, if bus combining unit A and the state consistency of bus combining unit B, inspection is all put
Repairing or do not put maintenance, low week protection voltage switching device P acquiescence takes the data of bus combining unit A, and by 4
Female voltage and 5 female voltages send low all protection devices W to by two transmission channels after splitting；If bus merges
The state of unit A and bus combining unit B is inconsistent, and such as bus combining unit A puts maintenance, and bus closes
And unit B do not puts maintenance, low week protection voltage switching device P takes the data of bus combining unit B, and by 4
Female voltage and 5 female voltages send low all protection devices W to by two transmission channels after splitting；If bus merges
The state of unit A and bus combining unit B is inconsistent, and such as bus combining unit A does not put maintenance, bus
Combining unit B puts maintenance, and low week protection voltage switching device P takes the data of bus combining unit A, and by 4
Female voltage and 5 female voltages send low all protection devices W to by two transmission channels after splitting.
