Switchgear/GZDW DC power cabinet
First, switchgear scope of application
GZDW series switchgear/ DC power supply cabinet is suitable for operation power supply of 500kv and below substations, small and medium-sized power plants, electrified railway, industrial and mining enterprises change (with) electric room, as high-voltage switch, relay protection, automation equipment, accident lighting. Control source.
Second, switchgear standards
GB3859-83 "semiconductor power converter", DL / T459-92 "nickel-cadmium battery DC screen (cabinet) order the technical conditions"
DL / T637-97 "valve-regulated sealed lead-acid battery ordering technical conditions"
DL / T5044-95 "Thermal power plant, substation DC system design technical specifications," ZBK45017-90 "Electricity
Force system with DC screen general technical conditions "
Third, the use of environmental conditions
Altitude: less than 2000m;
Ambient temperature: -5 ℃ ~ 50 ℃
Relative humidity: ¡Ü 90% (20 ℃ ¡À 50 ℃)
No strong vibration and shock, no strong electromagnetic interference;
switchgear Should be used in non-corrosive metal box damaged insulation of the gas, no conductive, explosive media occasions.
Fourth, switchgearsystem features
Charge floating charging device using high-frequency switching power supply module, n +1 redundant hot backup,
Automatic current sharing, reliable performance, high power factor. System modular structure can be hot-plug, easy maintenance.
Battery intelligent management, according to the system set the charging curve to complete the battery charge, float the whole process,
Without human intervention, and can be charged on a regular basis to compensate for the battery charge caused by long-term floating charge shortage, the battery charge voltage with temperature compensation automatically.
Charging module using the dual mode, can be controlled to run but also work independently, the system is running more secure.
Perfect protection, the AC input, DC output over / undervoltage, the module output short |
