Application
ZMZ-C series intellect integration power capacitor is new reactive
compensation equipment which is 0.4kv low voltage distribution
electric net,high save power,reduce wire loss,improve power factor
and power quality. It make up by intellect testing unit over zero
input switch circuit and protect unit,two pcs(△)or one pc(Y)low
voltage capacitor. This capacitor replace for low voltage power
capacitor which is make up by intellect controller fuse and combine
switch or contactor,thermal relay. Low voltage power capacitor
indicate lighting and other component of bank which connect one
conductor make up to auto reactive compensate equipment. It change
tradition reactive compensate big volume and very strong
instruction mode. So new power capacitor has good compensate
function,low volume,low power loss,good price,save cost,and using
convenient,maintain is easy and long life,reliability is best,it
suitable modern intellect electric net reactive compensate
demanding.
Functional characteristics
- Intelligent measuring and control system
The sampling system of current and voltage adopts 32-bitbuilt-in
MCU made by Corex-M4,able to collect the signals quickly, it can
realize the high accuracy of measuring three-phase current,
voltages, active power, reactive power,transparent power and etc
system parameters,calculating and analysis of harmonic waves.
- Human and machine exchange system
Displaying monitor adopts LCD panel, Chinese m nu,display the inner
temperature,current,voltage and harmonic parameters at real
time,push keys to seek the parameters and running status, also able
to set over-voltage,under-voltage,
under-current,over-temperature,over/under compensation data,can be
saved in case of power failure.
- Intelligent connecting with system
Rs485 comm port, built-in MODBUS-RTU protocol,able to realize
remotely monitoring and controlling. When several products are
connected with system in parallel, they will automatically produce
one master machine,the others become the slave machines,forming a
reactive power compensation system; if one of machine is out of
service it does not influence on others operating, if the master
machine exit the working,the system will auto produce anew master
machine,highly intelligent operation.
- Intelligent switching system
Really switching through zero current, auxiliary transistor circuit
is not needed, this system adopts the independent CPU to control
the switching operation at passing zero.switching at zero,no
surging current, no arcing,fast response,improve the reliability
and service life of the equipment.
Cooperated with high performance power capacitors,good
radiation,small size,long service life,consequently it can ensure
the complete-set equipment with high safety and reliability.
