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 YB:series box-type substation combines high voltage electrical equipment, transformer, low voltage electrical equipment into a compact switchgear for power distribution It is used for high-rise buildings in cities, urban and rural constructions, residential area, high and new technology development zone, small and medium-sized factories, mines, oil fields, and temporary constructions etc for receiving and distributing power in power distribution system. This product has strong complete sets, small size, compact structure, safe and reliable running, convenient maintenance, as well as the feature of mobile. The floor area is only 1/10 to 1/5 of the regular civil engineering type substation with same capacity greatly reducing the construction costs. It can be used in the ring network distnbution system and also can be used in dual power supply or radiation terminal power distribution system. It is the first selection of building and reforming the transformer substations in urban and rural areas. The design of the device meets the following standards: GB/T 17467 "High/ low voltage Preinstalled switchgear " and IEC 1330 standards. This product is composed of high voltage electrical equipment, transformer, low voltage electrical equpment t is divided into three unction compartments; high voltage compartment, transformer compartment and low voltage compartment. High voltage compartment has complete functions. The high voltage compartment uses HXGN- 12 ring network cabinet to compose the primary power supply system and can be arranged into various way to supply power; ring network power supply, terminal power supply and dual power supply etc, and can be equipped with high voltage measuring components to meet the need. Transformer can choose S9-M, SC(B) and other oil or dry types of transformers with low loss, Transformer compartment is equipped with automatic forced air cooling system and lighting system. Low voltage compartment adopts panel installation or cabinet installation according to the customer needed power supply scheme. Low voltage compartment is composed with power distribution. lighting distribution, reactive power compensation, power metering and other functions to meet different requirements of users and facilitate the management of power supply and improve the quality of power supply. 2.Working Conditions Altitude:≤1000m Ambient temperature: -25ºC~+40ºC and the average temperature in 24 h must below 35ºC The average temperature within 24 hours is not more than +35ºC Earthquake Acceleration: horizontally ≤0.4m/s²; vertically≤m/s² It is applicable in the place without violent vibration and the potential explosion. 3.SpecificationsNo | Item | Unit | High Voltage Electric Equipment | Transformers | Low Voltage Electric Equipment | 1 | Rated Voltage | kV | 7.2, 12 | 6/0.4; 12/0.4 | 0.4 | 2 | Rated Capacity | kVA | | (1):50-630,(2):80-1600 | | 3 | Rated Current | A | 630 | | 100-2000 | 4 | Rated Breaking Current | A | Load Switch 630A/SF6 Switch 630A | | 15-63 | 5 | Rated Breaking Current | kA | Composite apparatus depends on fuse | | 15-63 | 6 | Rated Short-time Withstand Current | kA | 20*2 | 200-400kVA | 15X1 | 7 | Rated Short-time Withstand Current | kA | 12.5*4 | >400kVA | 30X1 | 8 | Rated Peak Withstand Current | kA | 31.5; 50 | 200-400kVA | 30 | 9 | Rated Peak Withstand Current | kA | 31.5; 50 | >400kVA | 63 | 10 | Rated Closing Current | kA | 31.5; 50 | | | 11 | Power Frequency Withstand Voltage(1min) | kV | Phase to earth and phase to phase 42 | Oil type35 | <300V, 2 | 12 | Power Frequency Withstand Voltage(1min) | kV | Isolating fracture 48 | Dry type 28 | >300V, 2.5 | 13 | Lightning Impulse Withstand Voltage | kV | Phase to earth and phase to phase 75 | 75 | | 14 | Lightning Impulse Withstand Voltage | kV | Isolating fracture 85 | 75 | | 15 | Protection Degree of Cabinet | | IP3X | IP2X | IP30 | 16 | Noise Degree | dB | | Oil type<55 Dry type<65 | | Note | When the capacity of the transfer is lower 200KVA, the item 5 and 6 are not required. |
