Indoor AC Medium-Voltage Vacuum Load Switch Model Fzn21-12d/T630-20
This type of HV vacuum switch-fuse combinations widely serve in the power system for three-phase AC 10kV and 50Hz or in the urban network reconstruction, mineral & industrial enterprise, tall buildings and public facilities by coordinating with power distribution assembly, ring-network switchgear and combination-type substation. It can also function as ring-network power supply unit or terminal unit to distribute, control and protect electricity. The combinations conform to the following standards: IEC60265-1/FDIS, IEC60420, GB16926 and GB3804.
The combinations feature high breaking capacity, security and reliability, long electric endurance, frequent operation, compact volume, light weight and non-maintenance. It also has the capacity to break rated current, overload current (FZRN21-12D/T125-31.5 can break short-circuit current) and to prevent the equipment from operating under phase open. It has a visual clear-ance between open contacts. Fitted with earthing switch
With making capacity and electric-driven spring-operating
Device. It can perform teleactuation and telecontrol.
Structure feature:
1. The combinations are composed of frame, discon-nector (the current limiting fuses are fitted in the disconnector), vacuum arc-extinguishing chamber, earthing switch and spring-operating device etc (See fig. 1).
2. The combinations feature compact structure, small volume, long endurance, high capacity to make and break and convenient operation and maintenance. Fitted with spring-operating device, the vacuum switch stores energy by motor (manual energy storage also available). There are two ways for closing: Solenoid closing and manual closing. The interlock among switch disconnector, vacuum switch and earthing switch (mechanical interlock) can prevent misoperation.
Wooden case.
Supplier: Japanese quality switchgear components, breakers, magnetic contactors, switches, pilot lights, pushbuttons, panel instrumentations, power management meter, protection relays, transformers, inverters, ups.
WSD-VZF(R) -27/630-25 removable vacuum load switch + fuse combination electrical appliances (hereinafter referred to as combination electrical appliances) is a new generation of three-phase AC 50Hz, rated voltage 27kV indoor switchgear developed according to unique design concept and market demand. It is widely used in indoor armoured air insulated switchgear. It meets the requirements of GB3804-2004, GB16926-1997 and other standards. Under normal operating conditions, as long as the technical parameters of the vacuum switch are within the range, it can ensure the safe and reliable operation of the corresponding voltage level of the power grid. Environmental Conditions for Use The ambient temperature should not be higher than + 40, not lower than 10Â (storage and transportation allowed at 30) Elevation does not exceed 1500m. Relative humidity: the daily average is not more than 95%, the monthly average is not more than 90%, the daily average of saturated vapor pressure is not more than 2.2 x 10-3 Mpa, and the monthly average is not more than 1.8 x 10-3 Mpa. Earthquake intensity does not exceed 8 degrees. No fire, explosion danger, serious pollution, chemical corrosion and violent vibration.
6-35kv medium vollage power cable selection with cross-linked polyethylene insulation and plastic Sheath material, insulation layer USES the three co-extrusion technology, full automatic Change control. Such products, aging resistance, corrosion resistance, environmental stress not only electricity Gas properties and good mechanical properties, and has a simple structure and outer diameter Small, light weight, easy to use and elaborate divide not restricted, Public places such as crowed, place closed space.
