The quantity of the operation pole of failure；Control device handles constraint information for config failure, and troubleshooting constraint information includes
Logic is restarted in operation pole, and operation pole restarts logic and runs whether pole can be restarted simultaneously in direct current system for constraining；Control
Device processed is also used to restart operation pole in direct current system according to troubleshooting constraint information, failure operation number of poles.This
The embodiment of utility model is used for direct current system.
Utility model content
The utility model provides a kind of direct current system, this mode of connection solves the change outlet of AC power source switching or supply station
When failure, battery group failure just at the right time at this time, the problem of will lead to direct current system power loss, to achieve the goals above, use with
Lower technical solution, present patent application include: control bus, bus, alternating current inlet wire switching device, charging module, battery, decompression
Silicon stack, control module, the change of No. 1 station, No. 2 stations are with becoming, and No. 1 station is connected to bus with change lead-in cables, and No. 2 stations are used flexible
It crosses cable and is connected to bus, and No. 2 stations with flexible cable of crossing are connected to control module simultaneously, control module lead-in cables are connected to control mother
Line；The bus draws both threads cable and is connected to alternating current inlet wire switching device, and the alternating current inlet wire switching device is drawn cable and is connected to
Charging module, the charging module is connected to decompression silicon stack by cable, and battery is connected to decompression silicon stack also by cable, decompression
Silicon stack is connected to control bus by cable.
Preferably, the bus is 400v bus.
Preferably, it is described No. 1 station with become be connected on the cable of bus there are two breaker.
Preferably, No. 2 stations are connected on the cable of bus there are two breaker with becoming, No. 2 stations change and control modules
Between cable connect between two breakers.
Preferably, on the both threads cable between the bus and alternating current inlet wire switching device, on every cable all there are two
Breaker.
Preferably, No. 2 stations are equipped with a breaker with the cable become between control module.
Preferably, the cable between the charging module and decompression silicon stack is closing bus bar.
The utility model has the beneficial effects that if direct current cabinet there are closing bus bar, charging module and control modules to take
From different AC power sources；If direct current cabinet does not have closing bus bar, then charging module is divided into two, in this way, working as battery damage
When, any power loss of AC power source all the way will not influence direct current output, when only two-way exchanges whole power loss and battery damage
Direct current disappearance can just occur, when solving AC power source switching or supply station with outlet failure is become, battery group failure just at the right time at this time,
The problem of will lead to direct current system power loss.
Detailed description of the invention
Fig. 1 is the existing wiring diagram of this transformer station direct current system；
Fig. 2 is the wiring diagram of the utility model.
Specific embodiment
As shown in Figure 2 it is found that the utility model includes: control bus, bus, alternating current inlet wire switching device, charging mould
Block, battery, decompression silicon stack, control module, the change of No. 1 station, the change of No. 2 stations, wherein bus is located in ac panel, and control is female
Line, alternating current inlet wire switching device, charging module, battery, decompression silicon stack and control module are all located in direct current cabinet；Described 1
Number station is connected to bus with change lead-in cables, and No. 2 stations are connected to bus with flexible cable of crossing, and No. 2 stations accommodation simultaneously cable
It is connected to control module, control module lead-in cables are connected to control bus；The bus draws both threads cable and is connected to alternating current inlet wire switching
Device, the alternating current inlet wire switching device draw cable and are connected to charging module, and the charging module is connected to voltage dropping silicon by cable
