Load switch cabinet mechanism
- Product Description
-
First, the standard three-station design meets the requirements of "GB3804-2017 3~63kV AC high-voltage load switch"
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
