The inner wall of the fixed shell 11 extends to the interior of the fixed shell 11. A connecting seat 7 is fixedly connected to the middle of the front side of the circuit breaker body 5. A winding roller 9 is rotatably connected to the interior of the connecting seat 7. A servo motor 10 is fixed to the right end of the connecting seat 7. The output end of the servo motor 10 passes through the right wall of the connecting seat 7 and is fixedly connected to the right side of the winding roller 9. An electric wire 8 is provided on the winding roller 9. The bottom of the electric wire 8 is fixedly connected to the isolating switch 12.

A protective cover 6 is fixedly connected to the front side of the circuit breaker body 5.

[0024] Working principle: When the isolating switch 12 needs to be used, the staff first controls the electric push rod 13 to retract and drive the clamping plate 14 to separate from the circuit breaker. At this time, the servo motor 10 is started. The servo motor 10 drives the winding roller 9 to unwind through the output end. The winding roller 9 then drives the wire 8 to move downward. The wire 8 then drives the isolating switch 12 to move downward and move to the bottom of the circuit breaker body 5. At this time, the staff can operate the isolating switch 12 to prevent the operator from causing the risk of electric shock during use, and it is also convenient to respond quickly in an emergency.

[0025] Compared with the related art, the outdoor high-voltage vacuum circuit breaker with an isolating switch provided by the utility model has the following beneficial effects: by setting a servo motor 10, a winding roller 9, an electric wire 8, etc. for use with the isolating switch 12, the servo motor 10 drives the winding roller 9 to rotate and unwind the electric wire 8, and the electric wire 8 then drives the isolating switch 12 to move downward and move to the bottom of the circuit breaker body 5, thereby preventing the operator from causing the risk of electric shock during use, and also facilitating a quick response in an emergency.

[0028] Working principle: When the isolating switch 12 is not needed, the servo motor 10 controls the winding roller 9 to reel in the wire 8, and the wire 8 will be recovered by the winding roller 9, thereby pulling the isolating switch 12 to move upward and be stored in the interior of the fixed shell 11. At this time, the electric push rods 13 on both sides of the fixed shell 11 push the clamping plates 14 to clamp and fix the two sides of the isolating switch 12, preventing the isolating switch 12 from being hung for a long time and causing the risk of falling, making it convenient for the staff to use.
