  The introduction of DC system
Electric power DC operation power are the equipments which supply the continous DC power for the powerplant,water and electricity station adn all kinds of transformer substation of 500kv,220kv,110kv,35kv adn so on.The equipments inclule the close-open switch for disconnetting the circuit and all kinds of low voltage equipments including the apparatus,meters,the continous power supply protection,lontrol,the emergency illumination and so on,This is the extremely important tache for the power plant and substation to runn normally and swlely.
The PED series DC screen Arks which kehai Electric Appliance company produce are series-complete,variety-entire,and new-style DC arks,The arks have already passed the professioners'comment and identification of Electricity programming General Department organization in1997,The roducts have applied in the large-scale power plant,neclear plwer plant and substation,For many years,the uniwersal reflection is all right,The products are arranged in the recormmendatory product catalogue of the whole country and city grid reconstruction after these products accthorized by the Trade comm
PED-MS Microcomputer Mutral-control Type DC power supply
The reliability of PED-MS DC power system combination mutual-control power supply and the speciality of the intelligence manayement raise important function for microcomputer,improve the outpt accuracy greathy attaig the same level with the high freguency switch,enhance the management of the charge speliality and the failure alarm,and have the funtion of remote testing,remote communication and remote ailuusting ,It is wilddy used in the continuous power supply sits,such as irrigation works,electric power supply sits,such as irrigation works,elecctril power,railway,commnication.

speciality:
High reliability: It aulopts the wildely and maturely used and reliable commutation moduce,the charged module can alarm and automatically enter the offline condition to guarantee power supply outwared and the natural work of the storage battery when the microcomputer control module appears malfunction.
Intelligence management:The microcomputer inspection module can automatically manage and protect for muti-group batteries and multi-circuit module,proceeds the intelligence emulation for the speciality curve of storage battery,And multi-circuit module,proceeds the intelligence emulation for the speciality curve of storage battery.And if can select the charge way automatically accorcding to the storage battery capability and function condition,and make the storage bottery work with 100% load,At the sane time,it can active the battery and extense the life-span of the battery.

　

The operation interface is friendly: The control unit adopts the large screen of liguild crystal.The display aulopts Chinese chiracters AC power distribution, index of the battery,the preferrences and states of the commutation module can be swrveyed. It has the funtion of remote testing,remote communication,remote control and mets the request of modern electril power technolgy development.
correspnilence method: The system offers the correspondence methads of RS-232,RS-485,standard connects and MODEM corresponclence method,The users can select to proceed the remote corccentratiwe inspection management according to the actual circumstance and realize the real anmanned guard.
Function:
Inspection Function:switch the major and minor from multi-space commutation modules and control the method of the charge.
Examination Funtion: the examination for battery voltage,generatrix voltage,charge current,system output,general current and so on.
Alarm Function: It can release alarm of woice and light to any failure,and deposit the alarm information.
Protection function: It has the function of over-voltage lack-voltage,inpt and over-voltage,over-current,and over-heat output.
The main system Technology Parameter:
