Specific embodiment
A kind of high direct current cabinet of system reliability as described in Figure, using collecting and distributing control system, including AC distribution list
Unit, distribution monitor module, insulating monitoring module, monitoring module and charging module, the distribution monitor module monitors AC distribution
Unit inlet wire terminal voltage, the female controlling voltage of conjunction, cell voltage, load voltage and battery current, and the state of air switch；It is described exhausted
Edge monitoring modular is detected to the insulation situation of bus, separating brake branch and control branch, and is sent to monitoring using 485 buses
Module, monitoring module using order wire receive distribution monitor module, the data of insulating monitoring module and to charging module it is equal,
The conversion and control of floating charge.Make system that there is higher stability, reliability and extensibility.
While outstanding scheme is：The end of incoming cables of the Alternating Current Unit adopts two-way alternating current inlet wire pattern, the exchange of 1 tunnel
Inlet wire work is used, and 2 tunnel alternating current inlet wires are standby.When normal, the work of 1 tunnel, 2 tunnels are standby, when 1 tunnel alternating current power supply breaks down,
System is automatically switched in 2 tunnel alternating current power supplys, and when 1 tunnel alternating current power supply recovers normal, system is switched to 1 tunnel alternating current power supply again
On, improve the reliability of system.
The monitoring module receives distribution monitor module, the data of insulating monitoring module and to charging mould using order wire
The equal of block, the conversion and control of floating charge；Distribution monitor module is using order wire monitoring Alternating Current Unit, bus, battery, separating brake point
The voltage of road and control branch, electric current, and the state of the air switch of each branch；The existing communication function of order wire, has flow equalizing function again,
Make the convenient reliability of system.
