Abstract

A distribution room power supply method with multiple transformers comprises the following steps of arranging two groups of isolation disconnecting links on a low-voltage main line of a distribution room with overlarge loads and averagely dividing the distribution room into three groups according to the capacity of the loads; arranging a main transformer, an auxiliary transformer I and an auxiliary transformer II in the distribution room, respectively connecting the primary sides of the main transformer and the auxiliary transformers to a 10KV circuit, and respectively connecting the secondary sides of the main transformer and the auxiliary transformers to a distribution room II, a distribution room I and a distribution room III; in a production off season, using the main transformer to drive all the loads of the whole distribution room; in a production peak season, simultaneously putting the main transformer and the auxiliary transformer II into operation, using the main transformer to supply power to the distribution room I and the distribution room II, and using the auxiliary transformer II to supply power to the distribution room III; or simultaneously putting the three transformers into operation to respectively supply power to the three distribution rooms (I, II and III). The distribution room power supply method has the beneficial effects that the overload of one transformer can be greatly reduced by switching according to electricity consumption and electricity consumption seasons, the normal electricity utilization of users is ensured, and the power supply reliability is improved.

Description

Configure many transformer Tai district method of supplying power to

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 a kind of and can meet in time user power utilization demand, improve power supply reliability, the waste of capacity that 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 simultaneously.

Technical solution of the present invention is:

Configure many transformer Tai district method of supplying power to, step is as follows:

1, on the low pressure backbone in excessive district of load, two groups of isolation switchs are set and are respectively isolation switch I, isolation switch II, by isolation switch I, isolation switch ⅡJiang Tai district, according to load, be equally divided into three groups, be respectively Ⅰ,Tai district, platform district ⅡHe Tai district III;

Main transformer, auxiliary transformer I and auxiliary transformer II are set in 2 ,Tai districts, between two adjacent transformers, distance is 30 meters-50 meters, 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 ⅠHe Tai district, Ⅱ,Tai district, secondary knife switch ⅡJie Tai district III;

While 3, 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 when 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, Gei Tai district II, by auxiliary transformer II power supply Gei Tai district III;

5, produce the busy season when 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 Ⅰ,Tai district, the Gei Tai district ⅡHe Tai district III of powering respectively.

 

The invention has the beneficial effects as follows: easy to operate, reduced failure rate, can by switching, change season according to power consumption and electricity consumption, due to two spare transformers being set, during slack season, with whole district of a main transformer band, load, during the 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, guaranteed the normal electricity consumption of user, improved 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.
