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.Specifications1.General This product develops from adopting the latest foreign advanced technology, and combining domestic actual situation. The product has small size. convenient installation and maintenance, low noise, low loss, burglary prevention, strong overload ability and full protection etc. It is applicable in new-built communities, green belts, parks, station hotel, construction sites and airports etc. YBW-12 series American type preinstalled transformer substation is applicable to 10 kv ring network power supply, power supply system of dual power supply or terminal power supply system as power transforming measuring compensation controlling and protecting devices. This product meets the following standards: GB/T17467-2010 "High and Low Voltage Preinstalled Transformer Substation" and DL/T1537-93 "6 to 35 KV Box Type Transformer Substation Ordering Technology Specifications". 2.Structure Features Completed isolation, omnisealed, less maintenance, and reliable security; Compact structure, low height, small size (1/3-1/5 of the European type transformer substation with same capacity); Detached box type can be adopted to avoid the pollution from the oil in transformer. Double fuses protects the high voltage side to lower the cost of the whole set. Either ring network or terminal can be used Cable heads can be plug in and out urgently under the 200A load current. Cabinet uses cellular double composite panels for insulating and cooling. Electronic protector of lack phase at the ow voltage side can quickly break the main switch when there is any unnormal voltage happens. Oil type load switch or F6 load switch at the high voltage side can be electrically upgraded for the basic automation of distribution network. Oil type S9 or S11 (with better performance) is adopted as the transformer. 3.Working Conditions Altitude: ≤1000m Ambient temperature -35ºC~+40ºC Humidity: daily average ≤95%, monthly average ≤90% Installation Place: It is applicable in the place without fire, possible explosion corrosive and chemical corrosive gas and with good ventilation and the inclination to the floor can not be over 3°. 4.Specifications of Transformer SubstationItem | Unit | Data | Rated Voltage | kV | 10/0. 4 (high voltage/low voltage) | Maximum Working Voltage | kV | 12 (high voltage side | Rated Frequency | Hz | 50 | Rated Capacity | kVA | 50-1600 | 1min Power Frequency Withstand Voltage | kV | 35 | Lightning Impulse Voltage | kV | 75 | Cooling Type | | Oil type with self cooling | Breaking Current of High Voltage Backup Fuse | kA | 50 | Breaking Current of Plug-in Fuse | kA | 2.5 | Temperature | ºC | -35~+40 | Coil Allowable Temperature Rise | ºC | 65 | No-load Tap Changer | | ±5% or ±2×2.5% | Noise Degree | dβ | 50 | Protection Degree | | IP43 | Specifications of Transformer S9 series transformer has low loss, good overload ability, strong anti-circuit performance, tightened fastener, and no suspended core And also S10 series and 511 series with better performance can be chosen.capacity kVA | Voltage kv | Connecting Group Number | No-load Current % | No-load Loss kw | Impedence Voltage % | load Loss w | High Voltage | Low Voltage | S9 | S10 | S11 | S9 | S10 | S11 | S9 | S10 | S11 | 50 | 10±5% or ±2×2.5% | 0.4 | Dun11 or YynO | 2.0 | 1.9 | 0.75 | 0.17 | 0.15 | 0.12 | 4.0 | 0.87 | 0.83 | 0.87 | 63 | 1.9 | 1.8 | 0.7 | 0.2 | 0.18 | 0.14 | 1.04 | 0.99 | 1.04 | 80 | 1.9 | 1.7 | 0.7 | 0.25 | 0.22 | 0.175 | 1.25 | 1.2 | 1.25 | 100 | 1.8 | 1.55 | 0.65 | 0.29 | 0.26 | 0.2 | 1.5 | 1.42 | 1.5 | 125 | 1.7 | 1.45 | 0.65 | 0.34 | 0.3 | 0.235 | 1.8 | 1.72 | 1.8 | 160 | 1.6 | 1.3 | 0.6 | 0.4 | 0.36 | 0.27 | 2.2 | 2.12 | 2.2 | 200 | 1.5 | 1.2 | 0.5 | 0.56 | 0.43 | 0.33 | 2.6 | 2.5 | 2.6 | 250 | 1.4 | 1.1 | 0.5 | 0.56 | 0.5 | 0.39 | 3.05 | 2.9 | 3.05 | 315 | 1.4 | 1.0 | 0.45 | 0.67 | 0.29 | 0.465 | 3.65 | 3.45 | 3.65 | 400 | 1.3 | 1.0 | 0.4 | 0.8 | 0.71 | 0.56 | 4.3 | 4.15 | 4.3 | 500 | 1.2 | 1.0 | 0.4 | 0.96 | 0.85 | 0.67 | 5.15 | 4.82 | 5.15 | 630 | 1.1 | 0.8 | 0.4 | 1.2 | 1.6 | 0.81 | 6.2 | 5.86 | 6.2 | 800 | 1.0 | 0.7 | 0.35 | 1.4 | 1.23 | 0.98 | 4.5 | 7.5 | 7.2 | 7.5 | 1000 | 1.0 | 0.6 | 0.3 | 1.7 | 1.5 | 1.15 | 10.3 | 9.8 | 10.3 | 1250 | 0.9 | 0.6 | 0.27 | 1.95 | 1.72 | 1.36 | 12.0 | 12.2 | 12.0 | Specifications of Load Switch Load switch s oil type with three phase connecting and spring operating mechanism.
