FKN12-12 series load switch and its combination of electrical appliances, including air pressure type load switch and vacuum load switch two categories, is the digestion and absorption of foreign advanced technology, combined with our user requirements to improve, by our factory to design, develop and become. Is a new generation of high voltage electrical products applicable to the city power grid construction and transformation needs. Performance of the GB/T3804″3-63KV AC high voltage load switch” and GB/T16926 “AC high voltage load switch fuse combination” standard entrusted to the China National Quality Supervision and inspection center of high voltage apparatus according to the latest national standards to conduct a comprehensive test, the main product is the domestic leading level of similar products. Distribution system, the product is widely used in factories, schools, residential areas, high-rise buildings and other three-phase alternating current, voltage 10KV, rated frequency 50Hz, as the acceptance and distribution of electric energy use, and can be used for ring switchgear, box type substation, opening and closing of the power distribution equipment.
The Normal Use of The Environment:
The normal conditions of use load switch and switchgear is suitable for the following, if the actual use of the environment condition is different from the normal conditions of use, shall be borne by the user and manufacture of both parties through consultation.
The ambient temperature: 40 ℃, lower limit:: -25 ℃;
Altitude: not more than 1000M;
Relative humidity: daily average value is greater than 95%, on average less than 90%;
Saturated vapor pressure: daily average value not more than 2.2×10-3Mpa, monthly average value not more than 1.8×10-3Mpa;
Installation location: no fire, explosion, pollution, chemical corrosion and frequent violent vibration of the place;
Earthquake intensity: no more than 8;
Load switch for the frame structure, unique structure compact, integrated isolating switch, load switch, fuse, grounding switch is one of the high voltage electrical products .
Isolating switch for direct drive type, motion direction and motion parallel to the direction of the vacuum interrupter. Separate switch has obvious partition port security barrier, when the grounding switch on at the same time, and the safety barrier grounding switch static contact linkage automatically charged (closed busbar chamber), repair or replace the fuse is absolutely safe.
Isolating switch, load switch on-off sequence mechanical procedure guarantee. Closing operation, isolating switch, load switch it on first after closing. The opening operation, load switch off after the first isolating switch gate.
A mechanical interlock to prevent mis-operation between load switch and earthing switch.
The load switch with lock, can easily switch cabinet and the switch when the door open or the door interlock, door unlocked, load switch can not operate, when the grounding switch does not switch on, the door cannot be opened.
Load switch for electric manual can realize remote control.
