Motility：Main electrical scheme system should be able to be flexibly adapted to various working conditions, particularly when a part of overhaul of the equipments or
When working condition changes, can accomplish that scheduling flexibly, is not interrupted to customer power supply by the method for operation of reversal switch.
Enlarging when should be able to very easily from primary construction to final wiring.
Economy：Main electrical scheme system also should ensure that the convenience running operation and the requirement meeting the specification in guarantee
Under, accomplish economical rationality, reduce floor space as far as possible, reduce investment outlay.
Utility model content
For solving the deficiencies in the prior art, the utility model discloses a kind of new Main Electrical Connection in Transformer Substation structure,
The system is particularly well-suited to 110kV transformer station, and is applied to power distribution automation degree height, the power supply reliability higher, power transformation of requirement
Site area is limited, have the urban core region that important power supply is worth.
For achieving the above object, concrete scheme of the present utility model is as follows：

During chopper, isolation is used, and arranges a loop, and concatenate a chopper on wherein one diagonal of described tetragon, breaks
What road device both sides were same is respectively equipped with disconnecting switch.
The main electrical scheme of a 110kV is drawn on the two neighboring summit of described tetragon respectively.
The beneficial effects of the utility model：
1. employ quadrangle and introduce the mode of a diagonal wiring and substantially increase power supply reliability；
2. chopper number and the ratio going out line number are 5：4, for 3/2 mode of connection, save the investment of chopper
Expense, has more preferable economy；
3. compared to 3/2, for 4/3 mode of connection, its structure due to not accounting for two buses, save electric substation
Occupation of land space, be particularly well-suited to that power distribution automation degree is high, power supply reliability requires that higher, substation location area is limited,
There is the urban core region that important power supply is worth.
Brief description
Fig. 1 is structure chart of the present utility model；
Wherein, 1- chopper, 2- disconnecting switch, 3- wire.
Specific embodiment：
Below in conjunction with the accompanying drawings this utility model is described in detail：
A kind of new Main Electrical Connection in Transformer Substation structure, including chopper 1, disconnecting switch 2 and wire 3, wherein, four
Described chopper 1 passes through wire 3 annular, one tetragon of connected composition, and described chopper 1 is respectively provided on two sides with disconnecting switch 2,
It is used for isolation during maintenance chopper 1, wherein one diagonal of described tetragon arranges a loop, and concatenate one and break
Road device 1, what chopper 1 both sides were same is respectively equipped with disconnecting switch 2.
Main electrical scheme A, B of a 110kV is drawn on the two neighboring summit of described tetragon respectively.
Although the above-mentioned accompanying drawing that combines is described to specific embodiment of the present utility model, not new to this practicality
The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel do not need to pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
