ndoor 12kv 210mm 630A Gas Insulated housing sf6 load break switch for RMU ring main unit

Summary
FLN36-12kV load break switch use SF6 gas as arc extinguishing and insulating.There are three work stations: opening,closing and grounding in the switch. It has small volume,installing easy-to use, strong environmental adaptability and other characteristics.

FLN36-12 load break switch and FLRN36 -12D load break switch plus fuse combination can be used to protect and control the electric equipments for power supply and transformer substations, which is especially suitable for RMU, cable branch cabinet and distribution switching substation.
Its performance indicators in full compliance IEC420,694,129 and national standards GB3804-2004“3.6kV-0.5kV high voltage AC load breaker switch”GB1985-2004“high-voltage AC isolation switch and earthing switch”, GB/ T11022-1999“common technical requirements for high-voltage switchgear and control equipment standards“, This is the main switching element RMU.
The load breaker switch is a collection multifunctional medium voltage switchgear of gates, sub-gate, earthing. In a fully sealed with strengthen the structure of the epoxy resin housing to filled with SF6 gas,0.05MPa , with the minimum parts to achieve the above three functions, to ensure product quality, improve reliability, maintenance-free. It can be safely run for more than 20 years in normal conditions.

Basic functions and features:
1.Load breaker switch adapts double fracture, rotary movable contact structure, with the following three kinds of operating
states: Closing,opening,earthing.
2.Using SF6 gas as an arc extinguishing and insulating medium, the main circuit seals by the upper and lower housing pouring epoxy resin, the conductive function is unaffected by external influences.
3.Good safety performance. If internal arcing occurs, the housing has an internal structure weak point, it will be rushed to open, followed by the cabinet above the shutter release arc red open air overpressure stream-oriented outside the cabinet, ensure that the switch cabinet security checks.
4.Load breaker switch sets gates, opening, earthing switch three at one, filled with SF6 gas encapsulated in epoxy resin housing, three-position interlock,compact structure,high security and reliability.
5.Small size, light weight, maintenance-free, easy and safe to operate.


Manual operating mechanism

K type spring dual-function operating mechanism: as a inlet control unit, the working principle of K type spring operating
mechanism is spring press and release.
Earthing operation: driven by the handle, upper crank arm rotates and presses spring 2 to store energy, when the max energy reaches continue rotate the rank arm, the energy storage spring starts to release energy and drive the upper trigger, enables the connecting bar to drive the crank arm, crank arm rotates and drives the moving contactor for earthing.
Switch on operation: driven by the handle, lower crank arm 1 rotates, presses spring 2 to store energy, when the energy released, it drives the trigger 8, enables connecting bar to drive the crank arm, crank arm rotates and drives the moving contactor and load break switch turns on.
Switch off operation: rotate the main shaft crank arm counterclockwise by the handle, release the energy storage spring and the load break switch turns off.
A type spring dual-function operating mechanism: as a outlet control unit. Working principle of A type mechanism is same as K type, in addition, it has fuse striker trip function.
For A type mechanism. Electromagnetic trip is also available for customers requirement.
Switch on operation: driven by the handle, lower crank arm 1 rotates to press switch on spring 12 and switch off spring 8 at the same time, to provide sufficient energy required by switching off.
When the lower crank arm 1 buckles the pin and drives trigger to move, it makes the lower roller wheel tripped, and release the switch on spring and load break switch turns on.
Switch off operation: press the switch off button or push the trip pin 2 by the fuse striker, release the spring and load switch turns off. Earth operation: earthing operation of A type mechanism is the same as that of K type.

Motorized operating mechanism

Motor operation can be added to both types of operating mechanisms, which means it can be operated manually or motorized.
Operating voltage: DC48V AC/DC 110V 220V
