Along with the electric power profession
vigorously development, the small power plant domain carried on in the
infrastructure vigorously invested, day by day was also exuberant to
the center low-power power source demand, railroad and so on special
net domain also so. Can the industry limited company for satisfy
the market demand in present Shenzhen, strengthens the ZNBW series abc
power unit in the center, the low-power domain competitive ability,
composes the electrical power system development by the wall
suspension type rectifier to raise the program. Can the industry
take the ZN-GKM2.5/220 switch rectifier as the foundation, has
composed ZNBW wall hanging power source 7AH, 10AH, 17AH as well as the
24AH system, the wall hanging power source which Shenzhen can the
industry limited company produce (microcomputer high frequency switch
wall suspension type direct-current power supply system) in June, 2005
through the Chinese electric power academy of science electric power
industry power equipment and the measuring appliance performance test
test center pattern experiment.
First, application scope
The ZNBW series wall hanging (sets up) the formula power
source is one kind which Shenzhen can the industry limited company
promote uses in below the 30Ah intelligence electric power to use the
wall suspension type direct-current power supply system. Is
suitable to the small transformer substation, the belt switch 电览
divides meets the box, the intellectualized make and break,
intelligent box load switch and a direct current operating mechanism
and so on type transformer substation, ring net cabinet minute
floodgate, 合闸, the protection, the control with the direct-current
power supply, also may use in the small power plant and the switching
house emergency lighting. This system intellectualization
management, structure simple, the installment, the operation and the
maintenance extremely simple, are all convenient.
The wall hanging electrical power system function (detailed
material asks you to land http://www.zhengneng.com/ our
company website to examine) in the original foundation may increase
the battery to inspect unit, the generatrix insulation unit, the flash
installment and in domestic first development passable GPRS, Internet
Explorer has passed on system all numbers in, realizes the true
long-distance control.

14. insulations characteristics: The output to the
place, the input to the place, the input to outputs adds 2KVAC to leak
the electric current to be smaller than 30mA time 1min not to have
绝缘击穿.
15. working conditions temperature: -15 ~ +45 ?br> Third, system composition and structure
1. Exchange input unit:
A) The single-channel or a pair of road exchange the
220VAC input (to see plan one); B) 1 the road exchanges 220VAC
to input,1 group PT to supply power the 100VAC input (to see plan
two).
2. Intelligent monitoring unit:
Uses 4 lines ×8 to arrange in order the LCD Chinese character
demonstration;
Standard four lightly touch the button operation;
Intellectualized battery charge management function.
3. High frequency switch module:
2 ZN-GKM2.5/220 (ZN-GKM3.5/110V) the rectification module, the
single-phase three exchanges input, 220VDC/2.5A (110VDC/3.5A) outputs,
the module and the machine-hour can independent flow, can real-time
self-checking.
4. Direct current 馈线output:
2~4 road 合闸 output, 2 groups controls outputs;
5. Falls presses the installment:
1 2.5A/35V falls presses the module, monitors internal automatic
control, falls presses the precision for ±4V. Shenzhen can industry limited company Zhong Nengrong all
