specific Embodiment 1
[0035] Such as figure 1 as shown,
[0036] The invention discloses an interlocking isolating switch for a 110kv power grid, comprising a switch frame 1, a moving knife mechanism 4, a static knife mechanism 3, a ground knife mechanism 2, a moving knife electromagnetic mechanism 44, a ground knife electromagnetic mechanism 23, a moving knife Lock linkage mechanism, ground knife lock linkage mechanism, and switch self-locking mechanism, moving knife mechanism 4, static knife mechanism 3, ground knife mechanism 2 are arranged on switch frame 1, and moving knife electromagnetic mechanism 44 is arranged on moving knife mechanism 4 and uses For locking the moving knife mechanism 4, the ground knife electromagnetic mechanism 23 is set on the static knife mechanism 3 for locking the ground knife mechanism 2, and the moving knife lock linkage mechanism is connected in series on the ground knife mechanism 2 of the three-phase isolating switch, and the ground knife lock linkage mechanism ...
specific Embodiment 2
[0043] Locking system based on implementing 1 disconnector, including:
[0044] The moving knife locking unit includes a 10kW-15kW moving knife motor 46, a 2m-2.2m long moving knife column 42, a 4m-4.5m long moving knife bar 41, a current sensor 43, an electromagnetic lock, and a moving knife lock mechanism; The column 42 is movably connected on the switch frame 1, and the movable knife rod 41 is horizontally arranged on the top of the movable knife column 42, and the movable knife motor 46 is connected to the bottom of the movable knife column 42, and the rotation of the movable knife motor 46 drives the movable knife column 42 to rotate. The ratio of the rotating speed of the moving knife motor 46 to the rotating speed of the moving knife column 42 is 300-350, and the rotation angle of the moving knife column 42 is 0-95 degrees; The induced current in the current sensor 43 is not less than 30A, and an insulating layer is arranged on the current sensor 43, and the insulating ...
Embodiment 2
[0048] Based on the locking system of the isolating switch in embodiment 2, the control method of the interlock unit:
[0049](1) When the moving knife column 42 of the moving knife mechanism 4 needs to rotate, the control will reduce the current on the isolating switch to zero, and the moving knife lock mechanism on the three-phase isolating switch will be unlocked. Under the action of the rod, it moves up or down at the same time, and the triangular structure composed of the moving knife connecting rod and the moving knife lock mechanism can strengthen the stability of the structure, so that the three-phase isolating switch can be unlocked or locked at the same time;
[0050] (2) When the movable knife column 42 of the isolating switch is rotated to the disconnected position, the movable knife column 42 pulls the self-locking buckle located at the lower end of the movable knife column 42, and the self-locking buckle acts on the self-locking rod with a pulling force of 50N-80N...
