Description
Technical field
The present invention relates to substation line design fields, more particularly, to a kind of substation's connecting structure for electrical equipment.
Background technique
The connecting structure for electrical equipment of substation is the important content for being related to the safety in production operation of substation.One operation side
Formula is designed into quality and directly influences to whether scientific and reasonable, safe and reliable big problem of powering.The current typical method of operation
It is very more, but considering due to scale of investment and economic benefit, eventually lead to the consequence that need to sacrifice power supply reliability.As Fig. 1 is
Current each most common main wiring mode of application in substations, has the following problems:
1, when some feeder breaker failure, heavy current breaker need to be disconnected and overhauled, this results in whole mother
Line has a power failure, and also needs to have a power failure so as to cause other feeder lines to cooperate the significant deficiency of maintenance；
2, and then due to a upper problem cause, influence that face is big, and customer interrupted number is more, maintenance need to be completed as early as possible as early as possible to user
Telegram in reply is pressed for time, risk height；
3, it is also due to first problem, causes all users on this bus to have a power failure, and then lead to poor user experience,
Number is complained to increase sharply.
Summary of the invention
The present invention provides one kind and is not only able to satisfy economic needs, but also is able to satisfy reliability requirement substation connecting structure for electrical equipment.
In order to reach above-mentioned technical effect, technical scheme is as follows:
A kind of substation's connecting structure for electrical equipment, the substation are provided with main bus-bar and auxiliary bus-bar, including the first height presses off
Close unit, the second high voltage switch unit, several low tension switch units and switch unit；Transforming plant main transformer is through the first high-voltage switch gear list
Member connection main bus-bar, transforming plant main transformer are also connected to auxiliary bus-bar through the second high voltage switch unit；Several low tension switch units
One end is connect with main bus-bar, and the other end is connect with feeder line；One end that each low tension switch unit is connect with feeder line is also through switching
Unit is connected to auxiliary bus-bar.
Preferably, first high voltage switch unit and the second high voltage switch unit are tie breakers.
Preferably, the low tension switch unit is feeder breaker.
Preferably, the switch unit is disconnecting link.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
The present invention is gone wrong, at once can be shifted load, main bus-bar is full using two sections of buses point column arrangement, a feeder line
Load can shift a part of load to auxiliary bus-bar, and main bus-bar overhauls, and load can be transferred completely into auxiliary bus-bar, main mother
Line failure load is temporarily transferred to auxiliary bus-bar, it can be achieved that being not only able to satisfy economic needs, but also be able to satisfy reliability.
