Product Description
1.GeneralGZDW-06 direct current panel with cadmium nickel storage battery is the updating products for the result of many years of manufacturing experience, of collecting hundreds of substation operation records, of widely adopting the opinions from units of design and use, and of solving the problems for old type products. It is applicable to small and medium-sized power plants in power system transformer substations, and the distribution of industrial and mining enterprises, as the switching power supply of high voltage DC circuit breaker operating mechanism loop control relay protection, signal circuit, and DC power supply of emergency lighting.2.Operating PrinciplesGZDW type direct current panel is equipped with 2 or 3 sets of high frequency switch rectifier device, One set of high frequency switch supplies the power to the control busbar directly in the way of voltage stabilization. Another set of high frequency switch charges the storage battery mainly and floatingly in the way of current stabilization. So the storage battery can supply the closing busbar directly or the storage battery can supply the control busbar by lowering voltage through hanging chains to ensure that the control busbar can keep continuous voltage under any circumstances.3.SpecificationsRated Input AC Voltage | 380V±15%V |

4.Structure FeaturesHigh frequency switch replaces ferromagnetic saturation type main charge machine and floating charge machine of the traditional products and overcomes low stabilization accuracy, low precision of steady, loud noise, and high temperature rise of the traditional products.The transferred part of the spare channel adopts non-contact switch to switch in.This direct current panel uses the best way to charge the storage battery: constant current for earlier period, constant voltage for later period and these two periods can exchange automatically.The direct current panel has such protection functions: stabilize current automatically, stabilize voltage dynamically, limit current, protect circuit, and protect over voltage.The whole cabinet can output signal contacts of busbar voltage, busbar grounding, and battery charger fault etc.
