○ National key product
in new plan Reported by CCTV repeatedly
○ ¥20 million
guarantee by Min an insurance
○ Integrate Save
electricity 30%
○ Used in the ministry
of science and technology, the general hospital of China PLA and other more than 1000 energy saving program in countrywide
If we can apply the
energy saving device to every elevator, we will save 11.4billion kWhs energy, just like saving 3,800,000 ton standard coal, reduce 9,950,000 ton carbon dioxide, 32000 ton sulfur dioxide
and 28,000 ton nitric oxide gas waste.
SYSTEM
FEATURES
1.We adopt PWM
technology to output correct phase, and restrain higher harmonic effectively.
2.We adopt DSP CPU,
which has high speed, precision, stability and anti-jamming
ability.
3.We adopt
self-diagnostic techniques to ensure the accurate of output voltage, and in case of current post back, to make the frequency convertor out of influence.
4.Voltage distortion:
<5%, fit the harmonic requirements of IEC61000-3-2 and GB/T14549.
5.It can be used in
network connection with AC150~460Vdirectly through a reactor or filter. Electricity saving will be obvious in frequent braking situation.
6.Energy conversion
rate can reach above 97%.
7.Empty load up can
save 35% and Full load down can save 45%.
8.Indicate the numbers
of pitch point according real time.
9.Twin channel protect
installed internally.
10.Building block
design, support power extending.
11.Support data
teletransmission.
ADVANTAGES
1. It realized the
four quadrant operation of frequency converter system.
2. Braking energy was
recycled, increase the efficiency of system greatly. The
facilities for reduce
temperatures in elevator machine room can be closed.
3. The heat
productivity of system is reduced , and improved the safety and comfortableness, also decrease the amount of work.
4. Improving brake
effect, adapt the requirements of prompt and frequent braking
action.
