The direct current cabinet main feature:
1, high reliability:
Adopt the modularized design of Switching Power Supply, the N+1 Hot Spare.Charging module can charged hot plug, and the mean time between maintenance reduces significantly.
Power bus and control bus can pass through the dropping equipment Hot Spare by charging module directly power supply separately.
Charging module adopts the natural cooling mode, and the mean free error time significantly improves, and can be used for environment facies to abominable place;
The low difference of hardware autonomous equalizing current technology, the maximum degree of unbalance of intermodule output current is less than 5%.
Lightning protection reliably and electric insulation measure, the insulation monitoring and warning device of apolegamy can real-time monitoring system insulation situations, guarantee system and personal safety.
IEC (International Electrotechnical Commission) is adopted in system design, international standards such as UL, and reliability and security has abundant assurance.
2, high-intelligentization:
Monitoring module adopts LCD to show audible and visual alarm.
Can carry out the parameter setting of system's various piece by monitoring module.Module has the function of smooth adjustment output voltage and electric current, possesses the automatic management function of battery.
Possess interface, combine with computer networking technology, the support to " remote measurement, remote control, remote signalling, the remote regulating " of power-supply system is provided, realize unattended operation with modern power electronic.
Storage battery autonomous management and protection, the terminal voltage of real time automatic detection storage battery, charging and discharging electric current, and the equal floating charge of storage battery carried out Based Intelligent Control, be provided with battery overvoltage/undervoltage and charging overcurrent audible and visual alarm.
Adopt international up-to-date soft switch technique, main devices adopts high-quality best brand of product;
Monitoring program adopts design idea of oriented object, and modularization programming helps program maintenance and upgrading;
Can carry out the parameter setting of system's each several part by monitoring module, have detailed online help function;
Modern power electronics technology combines with computer technology, realizes " remote measurement, remote control, remote signalling, remote regulating " and realization unattended operation to power-supply system;
Storage battery is management and protection automatically, the terminal voltage of real-time automatic monitoring storage battery, and the charge and discharge electric current, and control all filling and floating charge of storage battery, be provided with battery overvoltage/undervoltage and charging overcurrent audible and visual alarm.
But because various interface all is arranged on the rear side of direct current cabinet, carry out in direct current cabinet the place ahead in the time of operation, and inspection and maintenance must carry out to the back of direct current cabinet, not too convenient.Conventional direct current cabinet overall dimension all is designed to: long 800 millimeters, wide 600 millimeters, high 2200 millimeters, occupation space is bigger, also is not easy to carrying and transportation.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of improved direct current cabinet is provided, and inspection and maintenance can carry out in direct current cabinet the place ahead, and the technical scheme of employing is as follows:
Improved direct current cabinet of the present utility model, comprise rectification module, monitoring module, battery pack, pressure unit, power supply unit and at least one interface, monitoring module, battery pack, rectification module, pressure unit, power supply unit are installed in the direct current cabinet, it is characterized in that: described interface is located at the direct current cabinet front end.
A kind of scheme, described interface are remote communication interface.
Another kind of scheme, described interface is standard RS232 or RS485 serial line interface.
The third scheme, described interface are Ethernet interface.
Can also adopt other interface.
A kind of preferable scheme, the number of described interface is at least two, and each interface is selected from least a in remote communication interface, standard RS232 or RS485 serial line interface, the Ethernet interface.
The application is purpose further, is the volume that reduces direct current cabinet for effective, and the length of described direct current cabinet is 600 millimeters, and width is 600 millimeters, highly is 1600 millimeters.Through test of many times, the applicant gets the greatest degree of optimization the size of direct current cabinet not reducing parts, guaranteeing under the prerequisite of original function the size of direct current cabinet to be revised, and volume significantly reduces.
