> According to the report, starts from this June,
the nation will appear wide range to pull the floodgate to limit the
electricity, the peak time interval lacks the electricity province to
be able to achieve 24, most will be serious will be Zhejiang Province,
estimated the peak will lack 电达 95%. Creates sternly lacks
the electricity difficult position the reason to be very many, mainly
is the power plant construction insufficiency and the coal supply
tense two big factors.
The national electric power company receives "95" the period
electric power supply surplus influence, "95" the last stage newly
begins to the electric power the special case strict control, caused
the recent years power station to go into production the capacity
seriously to be insufficient, satisfied the economical fast growth
with difficulty to the electric power demand.
Next country the security accident question which repeatedly
performs for the thorough settlement small coal mine, carried on to
the national small coal mine has been comprehensive 清整, "closed
down" one batch of existences securities hidden danger small coal
mine, simultaneously many large-scale coal mines also because many
originally thus appeared the underproduction, let the
thermoelectricity generation bitter experience unprecedentedly
"煤荒".
Pulls the floodgate to limit the electricity to say to the
correspondence user that, can bring many inconveniently, for example
will not be able to be on-line wilfully "the surfing" in the wide
band, handset and fixed telephone because will be unable to put
through, but will become the ornaments Power cut initiation a
series of questions let the correspondence operation business be
anxious extremely, can not but carefully ponder: How can
safeguard the correspondence and the network does not sever manages?
What is the best solution also?
Operation business through the consultation, compared with the
existing many kinds of solution, they had not found the best means,
can not but use enlarges the battery capacity, the increase
rectification module quantity way, lengthens some on times;
Simultaneously enlarges the charging current, namely the
charging current from standard 0.1 ~ 0.15C, enlarges to 0.2 ~ 0.25 C,
hoped causes the battery rapid charge rate, achieves the occupied
state as soon as possible This plan merit is the technology
mature, 简易行, the shortcoming is invests the cost to be
higher, is unable the correspondence which safeguards continuously 3 ~
4 days power cuts to create not to sever the question, simultaneously
also causes the battery the service life greatly to reduce.
Moreover a plan is purchases the diesel oil power set the method
to solve the long-term power cut problem, but on the one hand because
the operation business load is the rectification load, to generator
power supply quality requirement higher, but the existing mature small
diesel oil power set uses the exciting winding, the structure complex,
the energy consumption is high, specially brings the rectification
load to be able to cause the wave mode distortion, affects the
rectification module the service life; On the other hand the
generator merchant is not extremely understood to the operation
business demand, therefore cannot completely satisfy the customer in
the function the need, operation business only can reluctantly use.
The our company displays own superiority in view of the above
question, and strong strongly collaborates domestically to have the
technical superiority the necessary merchant, success research and
development ?orange-red ?Xing Ran□he level intellectualized
kerosene engine emergency power supply system.
This system main application in the communication with 基站
the emergency power supply, is for alleviates the accumulator cell to
take the emergency power supply capacity is insufficient shortcoming.
Especially is suitable for frequently power cut, also off time
longer area nobody duty communication 基站.
The system takes the power with the diesel engine power set, has
the capacity to be big (6KW~11KW); City electricity \ kerosene
engine automatic cut over; The kerosene engine automatically
opens stops; Many kinds of alarm signal long-distance/wireless
communication; Independent radiation well ventilated
characteristic. Lengthened 基站 the original accumulator cell
life, enhanced 基站 throws transporting rate, reduced attendant's
work load.
The system major component diesel engine power set, we are
extremely careful in the necessary merchant choice We knew the
diesel oil power set is composed by the diesel engine and the
generator We have selected center the auspicious technology
cooperative production on the diesel engine "the two-cylinder V
forced-air cooling diesel engine", it has vibrates slightly, the noise
is low, automatic frequency adjustment (full load frequency shift
only<=±0.5%),工作柔和的特?且达到欧-II[排放标准。发电机采用获得国际新技术新产品奖的高能稀土永磁无刷发电机,其效率和功率因子?节能效果明显,电压波带整流负载无畸?完全满足客户对波性的要求. Electrical block diagram as follows:
