4. Structure Introduction
JT8(JN)-40.5 Type indoor high voltage grounding switch from the
undercarriage, touch knife, insulator voltage display devices
(sensors), closing spring, and three-phase short-circuit connection
contact copper components.
Brace is bent plate welded into a rectangular frame. Supply at both
ends with the assembly of the spindle bearings and bearing; a
display device voltage insulator (sensor) installed in the bottom
frame and top with J-type contact and bearing; touch knife spindle
mounted welding Shui arm, by closing spring drive shaft and drive
the touch knife switch on, so as to achieve the purpose of closing
short-circuit current.
When open and close, as long as the operating handle is rotated
with the spindle drive shaft coupled to the spring over the dead
point, closing by spring force acceleration. After closing the main
shaft connecting the crank arm and the operating shaft into a dead
point, it is possible to closing short-circuit current, touch knife
does not open when the dynamic current test.
5. Ordering Information
The grounding switch for a wide range of products please specify
the user type, size, distance, or gear crank arm mounting position
(left or right), whether with live display device. User if there
are special requirements, when ordering.
