Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment；Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1-3, a kind of direct current cabinet, including voltmeter 1, ammeter 2, touch screen 3, power module 4, feed out switch
5, feed out indicator light 6, pressure regulator 7, alternating current inlet wire terminal 8, feed out terminal 9, communication terminal 10, insurance 11, automatic duplicate supply 12,
Composite measurement unit 13, power module service entrance switch 14, cell switch 15, transition terminal 16, Hall sensor 17, current divider
18；Voltmeter 1, touch screen 3, power module 4, feeds out switch 5, feeds out the setting of indicator light 6 in a kind of direct-current cabinet ammeter 2
Cabinet door on, pressure regulator 7, alternating current inlet wire terminal 8, feed out terminal 9, communication terminal 10 is arranged in a kind of inner wall of direct-current cabinet
On；Insurance 11, automatic duplicate supply 12, composite measurement unit 13, power module service entrance switch 14, cell switch 15, transition terminal
16, Hall sensor 17, current divider 18 are arranged in the inside of battery cupboard；Alternating current inlet wire is used and is supplied power with double circuit, and can be spare each other,
Equipment medium-high frequency switch power module constitutes commutation system, and redundant configuration is spare each other when normal work, when a wherein mould
When block failure, the output of other modules is not influenced；Main circuit uses the dc circuit breaker of different breaking capacity, control is exported,
Combined floodgate output and accumulator output carry out rational the superior and the subordinate to system using the dc circuit breaker of different capacitance grade electric current and match
Close protection；Monitoring unit is with touch screen center in order to control, to the charging floating charging of straight-flow system, fault alarm etc.
It carries out automatically controlling, there is very strong anti-interference function；When normal, the operation of rectification module is controlled by touch screen 3, directly to control
Bussed supply processed；And be responsible for accumulator fill and floating charging, float charge voltage be 2.25 (× n), even charging voltage 2.33
(× n), charging current value is less than or equal to 0.1CA；High frequency switching rectifier module can not only be used for the working power of each branch, and can give
Accumulator charges, and closes the impact load in female circuit then by direct battery power；When AC power dead electricity, accumulator group is
It carves incessantly to bus discharge；After AC power restores normal, charging module can automatically charge to accumulator, protect
It is enough to demonstrate,prove battery group capacity, can again to be powered to control bus at any time；When accumulator is online, close
On feed out switch, corresponding indicator light is bright, shows that accumulator can be to feeding out loop power supply.
