Load switch cabinet mechanism
First, the standard three-station design (optional two stations), in line with the requirements of "GB3804-2017 3 ~ 63kV AC high-voltage load switch"Details
Second, the mature arc-extinguishing grid design ensures that the closing and arc-extinguishing arc is stable and reliable.
Third, select the disc spring to ensure that the contact pressure is stable and reliable for a long time.
Fourth, the plastic arm is subjected to low temperature experiments to ensure that it does not rupture or crack under low temperature conditions.
5. Reserve the grounding circuit copper bus interface to strengthen the grounding circuit closing and current withstand capability as needed.
Sixth, the grounding switch form is optional

Load switch cabinet mechanism
First, the standard three-station design meets the requirements of "GB3804-2017 3~63kV AC high-voltage load switch"Details
Second, the natural "five-proof" design (the load switch can be connected to the grounding switch after opening; the grounding switch can be combined with the load switch), mechanical and electrical double interlock
Third, the design has interlocking with the lower door panel (close the upper and lower door panels to separate the grounding switch; the grounding switch is closed to open the lower door panel), mechanical and electrical double interlocking
Fourth, the design has interlocking with the operating handle (the electric control loop is automatically cut off after the operating handle is inserted)
5. Redesigned door panel hard interlock, cancel the original steel wire (or plastic wire) design, interlocking is more reliable and stable
