Product Description

Description

BRFLN36-36an indoor high-voltage SF6 load switch, an switchgear with the rated voltage of 36kV/40.5kV, adopted with SF6 gas as an arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off and to-ground, and is characteristic in its small volume, its convenient installation and operation and its the great adaptability with surroundings.

 

BRFLN36-36 of an indoor high-voltage SF6 load switch and BRFLN36-36D of SF6 load switch plus fuse combination can function to protect and control the electric equipments for power supply and transformer substations especially being suitable for ring net cabinet, cable branch cabinet and distribution switching substation.

 

BRFLN36-36 of an indoor high-voltage SF6 load switch and BRFLN36-36D load switch plus fuse combination are complied with the standards of IEC60265-1-1998, IEC60420 etc.

Outline Dimension

Arc extinction

BRFLN36-36 load break switch adopts SF6 gas as the medium of arc extinction, when switch on and off, arc occurs and will spin under the magnetic field effect ion by the permanent magnet, cooled by the SF6 gas and extricated finally.This indoor SF6 load break switch and its fuse combination works with spring type operating mechanisms A and K, BRFLN36-36 load break switch equipped with the K spring operating mechanism is applied as the incoming control unit, while that equipped with A mechanism is applied as the outgoing protective unit and transformer unit.

1) "K" Type Spring Operating Mechanism

Working principle of K type spring operating mechanism is spring press and release( see fig 1. it's in off position)

A) Earthing operation

Driven by the handle, upper crank arm 4 rotates and presses spring 2 to store energy, when the max energy reached continue rotate the crank 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.

B) 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.

C) 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.

2) "A" Type Spring Mechanism

Working principle of A type mechanism is same as K type, in addition, it has fuse striker unbuckle function. For A type mechanism, electromagnetic unbuckle is also available on customers requirement.(see fig 2)

A) Switch on operation

 

Driven by the handle, lower crank arm 1 rotates to presse 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 unbuckled, and release the switch on spring and load break switch turns on.

 

B) Switch off operation

 

Press the switch off button or push the unbuckle pin 2 by the fuse striker, release the spring and load switch turns off.

 

C) Earthing operation

 

Earthing operation of A type mechanism is same as that of K type.
