Beneficial effect is: can change by switching season according to power consumption and electricity consumption, greatly reduce single transformer overload, ensure the normal electricity consumption of user, improve power supply reliability.
Description
Technical field
The present invention relates to a kind of many transformer Tai district method of supplying power to of configuration that meet seasonal need for electricity.
Background technology
There is the excessive phenomenon of seaonal load in some districts of agriculture electric power system in recent years, particularly to the harvest season, with every agricultural machinery half rated power operation, Circuit Fault on Secondary Transformer load will increase greatly, much larger than secondary side rated current, can make transformer secondary fuse failure, transformer heating, even cause more serious power grid accident, often power failure also can make a big impact to the normal electricity consumption of resident simultaneously, and power supply reliability is produced and had a strong impact on.
Summary of the invention
The present invention will solve the problems referred to above that prior art exists, provide one can meet in time user power utilization demand, improve power supply reliability, the waste of capacity that simultaneously can not cause transformer to cause for low year again, can meet many transformer Tai district method of supplying power to of configuration of seasonal need for electricity.
Technical solution of the present invention is:
Many transformer Tai district method of supplying power to of a kind of configuration, step is as follows:
1, on the low pressure backbone in excessive district of load, two groups of isolation switch are set and are respectively isolation switch I, isolation switch II, be equally divided into three groups by isolation switch I, isolation switch ⅡJiang Tai district according to load, be respectively platform district I, ⅡHe Tai district of platform district III;
2, main transformer, auxiliary transformer I and auxiliary transformer II are set in Tai district, 30 meters-50 meters of distances between two adjacent transformers, main transformer and auxiliary transformer I, auxiliary transformer II primary side are connect to 10KV circuit by a falling type switch, a falling type switch I and a falling type switch II respectively, main transformer, auxiliary transformer I and auxiliary transformer II secondary side are passed through respectively to secondary knife switch, secondary knife switch I and secondary knife switch ⅡJie Tai district II, ⅠHe Tai district of platform district III;
3, while producing dull season, load is less, a falling type switch II of a falling type switch I, secondary knife switch I and the auxiliary transformer II of auxiliary transformer I, secondary knife switch II are disconnected, now auxiliary transformer I, auxiliary transformer II do not put into operation, make isolation switch I, isolation switch II closure, by whole all loads in district of main transformer band;
4, produce the busy season in the time that load is larger, first main transformer is stopped using, then close isolation switch I, disconnect isolation switch II and disconnect, falling type switch of main transformer, the auxiliary transformer II of closing again and secondary knife switch, main transformer, auxiliary transformer II are put into operation simultaneously, by main transformer power supply ⅠHe Tai district of Gei Tai district II, by auxiliary transformer II power supply Gei Tai district III;
5, produce the busy season in the time that two transformers still can not meet need for electricity, first main transformer, auxiliary transformer II are stopped using, then disconnect isolation switch I, isolation switch II, falling type switch of main transformer, auxiliary transformer I and the auxiliary transformer II of closing again and secondary knife switch, main transformer, auxiliary transformer I and auxiliary transformer II are put into operation simultaneously, by auxiliary transformer I, main transformer and auxiliary transformer II power respectively Gei Tai district I, ⅡHe Tai district of platform district III.
The invention has the beneficial effects as follows: easy to operate, reduce fault rate, can change by switching season according to power consumption and electricity consumption, due to two spare transformers being set, when slack season, load with whole district of a main transformer band, when busy farming season, according to electricity consumption situation, a spare transformer or two spare transformers are put into operation, so greatly reduce single transformer overload, ensure the normal electricity consumption of user, improve power supply reliability, reduce the workload of changing or setting up transformer, stop potential safety hazard, meet in time user power utilization demand, the waste of capacity that can not cause transformer to cause for low year again simultaneously.
Brief description of the drawings
Fig. 1 is circuit system figure of the present invention.
Detailed description of the invention
As shown in the figure, many transformer Tai district method of supplying power to of this configuration, step is as follows:
1, on the low pressure backbone in excessive district of load, two groups of isolation switch are set and are respectively isolation switch I, isolation switch II, be equally divided into three groups by isolation switch I, isolation switch ⅡJiang Tai district according to load, be respectively platform district I, ⅡHe Tai district of platform district III;
2, main transformer, auxiliary transformer I and auxiliary transformer II are set in Tai district, 30 meters-50 meters of distances between two adjacent transformers, main transformer and auxiliary transformer I, auxiliary transformer II primary side are connect to 10KV circuit by a falling type switch, a falling type switch I and a falling type switch II respectively, main transformer, auxiliary transformer I and auxiliary transformer II secondary side are passed through respectively to secondary knife switch, secondary knife switch I and secondary knife switch ⅡJie Tai district II, ⅠHe Tai district of platform district III;
3, while producing dull season, load is less, a falling type switch II of a falling type switch I, secondary knife switch I and the auxiliary transformer II of auxiliary transformer I, secondary knife switch II are disconnected, now auxiliary transformer I, auxiliary transformer II do not put into operation, make isolation switch I, isolation switch II closure, by whole all loads in district of main transformer band;
4, produce the busy season in the time that load is larger, first main transformer is stopped using, then close isolation switch I, disconnect isolation switch II and disconnect, falling type switch of main transformer, the auxiliary transformer II of closing again and secondary knife switch, main transformer, auxiliary transformer II are put into operation simultaneously, by main transformer power supply ⅠHe Tai district of Gei Tai district II, by auxiliary transformer II power supply Gei Tai district III;
