During maintenance, the 10kV isolating switch can separate the equipment or line that needs to be repaired from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment.

[0003] Existing 10kV isolating switches often generate heat during operation due to the reduction of contact pressure of the isolating switch blades. At present, when dealing with the heating defect, it is necessary to shut down the line or dispatch a large live working vehicle to operate, which not only increases the operation and maintenance workload of the operation and maintenance personnel, but also poses the risk of electric shock and falling from a height during operation. To this end, the present invention proposes a live adjustable isolating switch. Summary of the invention

[0004] The embodiment of the present application provides an electrically adjustable isolating switch, which enables the isolating switch blade to be directly adjusted remotely while powered, thereby solving the heating problem of the isolating switch. It can not only reduce the operation and maintenance workload of the operation and maintenance personnel, but also fully ensure the safety of the personnel.

[0005] In view of this, the present application provides a live adjustable isolating switch, comprising: a base, an insulator, a switch blade and a blade adjustment device;

[0006] The two insulators are arranged on the base, and the tops of the two insulators are respectively connected to the switch through wiring boards;

[0007] The blade adjustment device is arranged on the switch blade and is used to adjust the tightness of the disconnector blade;

[0008] The blade adjustment device comprises a first movable piece and a second movable piece with spring screws respectively inserted into the left and right sides of the gate knife, and a driving assembly for driving the first movable piece and the second movable piece to move in opposite directions;

[0009] The first movable piece and the second movable piece are installed on the outside of the switch blade and are slidably connected to the switch blade respectively;

[0010] The driving assembly comprises a rotatable pull ring for cooperating with the insulating operating rod, a driving rod fixed at the lower end of the rotatable pull ring, a first gear arranged on the driving rod, and a second gear meshingly connected with the first gear;

[0011] A first rack matching the first gear is correspondingly arranged on the first movable sheet, and the first gear is meshedly connected with the first rack;

[0012] A second rack matching the second gear is correspondingly arranged on the second movable sheet, and the second gear is meshingly connected with the second rack.

[0013] Optionally, the switch blade is also provided with a remote control driving device;

[0014] The remote control driving device comprises a remote control device for communicating with the terminal device and a motor for driving the driving rod to rotate;

[0015] The remote control device is electrically connected to the motor.

[0016] Optionally, a driving gear is provided on the output shaft of the motor;

[0017] The driving rod is correspondingly provided with a transmission gear meshingly connected with the driving gear.

[0018] Optionally, the terminal device is a computer or a mobile phone.

When it is found that the isolating switch blade is heated due to the reduction of contact pressure, the isolating switch blade can be adjusted directly on the ground through the insulating operating rod. Specifically, the rotatable pull ring is rotated by the insulating operating rod, and the rotatable pull ring drives the first gear and the second gear to move in opposite directions, thereby driving the first movable piece and the second movable piece to move outward in opposite directions at the same time until they contact the spring screws on the left and right sides of the switch. At this time, the first movable piece and the second movable piece will be stuck in the gasket with the spring screw, and the spring on the screw will be deformed due to the force, and the deformed spring will generate a reaction force to act back on the first movable piece and the second movable piece, so that the first movable piece and the second movable piece press the switch inward, so that the switch blade is closed more tightly, which can effectively deal with the heating defect of the isolating switch blade.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] This application provides an embodiment of an electrically adjustable isolating switch. Figure 1 and Figure 2 .

[0037] The live adjustable isolating switch in this embodiment comprises: a base 1, an insulator 2, a switch blade 4 and a blade adjustment device, two insulators 2 are arranged on the base 1, and the tops of the two insulators 2 are respectively connected to the switch blade 4 through the wiring board 3, and the blade adjustment device is arranged on the switch blade 4, which is used to adjust the tightness of the isolating switch blade; the blade adjustment device comprises a first movable piece 7 and a second movable piece 6 with spring screws 10 respectively inserted into the left and right sides of the switch blade 4, and a driving component for driving the first movable piece 7 and the second movable piece 6 to move in opposite directions, and the first movable piece 7 and the second movable piece 6 are installed On the outside of the knife 4, and respectively connected with the knife 4 in a sliding manner; the driving assembly includes a rotatable pull ring 8 for cooperating with the insulating operating rod, a driving rod 11 fixed at the lower end of the rotatable pull ring 8, a first gear 12 arranged on the driving rod 11, and a second gear 13 meshingly connected with the first gear 12, a first rack 15 matching the first gear 12 is correspondingly arranged on the first movable sheet 7, the first gear 12 is meshingly connected with the first rack 15, and a second rack 14 matching the second gear 13 is correspondingly arranged on the second movable sheet 6, and the second gear 13 is meshingly connected with the second rack 14. Specifically, the driving assembly also includes a shell 9 fixed on the front side of the knife 4, the first gear 12 is located in the shell 9, the driving rod 11 is rotatably connected with the shell 9, and one end of the driving rod 11 extends into the shell 9 and is fixedly connected with the first gear 12; the second gear 13 is rotatably arranged in the shell 9.

[0038] It should be noted that: the live adjustable isolating switch can remotely and directly adjust the isolating switch blade when live, thereby solving the heating phenomenon of the isolating switch, which can not only reduce the operation and maintenance workload of the operation and maintenance personnel, but also fully ensure the safety of the personnel. When it is found that the isolating switch blade is heated due to the reduction of contact pressure, the isolating switch blade can be adjusted directly on the ground through the insulating operating rod. Specifically, the rotatable pull ring 8 is rotated by the insulating operating rod, and the rotatable pull ring 8 drives the first gear 12 and the second gear 13 to move in opposite directions, thereby driving the first movable piece 7 and the second movable piece 6 to move outward in opposite directions at the same time until they contact the spring screws 10 on the left and right sides of the switch 4. At this time, the first movable piece 7 and the second movable piece 6 will be stuck in the gasket with the spring screw 10, and the spring on the screw will be deformed due to the force, and the deformed spring will generate a reaction force to act back on the first movable piece 7 and the second movable piece 6, so that the first movable piece 7 and the second movable piece 6 press the switch 4 inward, so that the switch 4 blade is closed more tightly, which can effectively deal with the heating defect of the isolating switch blade.

[0039] The above is an embodiment of a live adjustable isolating switch provided in the embodiment of the present application. The following is an embodiment of a live adjustable isolating switch provided in the embodiment of the present application. For details, please refer to Figures 1 to 5 .

[0040] The live adjustable isolating switch in this embodiment comprises: a base 1, an insulator 2, a switch blade 4 and a blade adjustment device, two insulators 2 are arranged on the base 1, and the tops of the two insulators 2 are respectively connected to the switch blade 4 through the wiring board 3, and the blade adjustment device is arranged on the switch blade 4, which is used to adjust the tightness of the isolating switch blade; the blade adjustment device comprises a first movable piece 7 and a second movable piece 6 with spring screws 10 respectively inserted into the left and right sides of the switch blade 4, and a driving component for driving the first movable piece 7 and the second movable piece 6 to move in opposite directions, and the first movable piece 7 and the second movable piece 6 are installed On the outside of the knife 4, and respectively connected with the knife 4 in a sliding manner; the driving assembly includes a rotatable pull ring 8 for cooperating with the insulating operating rod, a driving rod 11 fixed at the lower end of the rotatable pull ring 8, a first gear 12 arranged on the driving rod 11, and a second gear 13 meshingly connected with the first gear 12, a first rack 15 matching the first gear 12 is correspondingly arranged on the first movable sheet 7, the first gear 12 is meshingly connected with the first rack 15, and a second rack 14 matching the second gear 13 is correspondingly arranged on the second movable sheet 6, and the second gear 13 is meshingly connected with the second rack 14. Specifically, the rotatable pull ring 8, the first gear 12, the second gear 13, the first rack 15 and the second rack 14 can all be made of stainless steel, which can ensure safe operation in harsh environments, never rust, and no gear jamming caused by rust.

[0041] It is understandable that when the first movable piece 7 and the second movable piece 6 are inserted into the spring screws 10 on the left and right sides of the knife gate 4, the spring on the spring screw 10 will be further compressed, and then under the action of the spring, the movable piece and the knife gate 4 will be pressed inward.

[0042] like Figure 3 As shown, the switch blade 4 is also provided with a remote control driving device, which includes a remote control device 17 for communicating with the terminal device and a motor 18 for driving the driving rod 11 to rotate, and the remote control device 17 is electrically connected to the motor 18. Specifically, as Figure 5 As shown, the remote control device 17 includes a Bluetooth module, a processor, a power supply and a motor drive circuit, wherein the power supply is electrically connected to the Bluetooth module, the Bluetooth module is electrically connected to the processor, the processor is electrically connected to the motor drive circuit, and the motor drive circuit is electrically connected to the motor 18. When in use, instructions can be transmitted to the processor via the Bluetooth module, and the processor sends a drive signal to the motor drive circuit, thereby starting the motor 18.

[0043] It should be noted that: by setting up a remote control drive device, maintenance personnel can adjust the tightness of the isolation switch blade by remote control, which is more convenient to use and further reduces the operation and maintenance workload of operation and maintenance personnel.

[0044] like Figure 3As shown, a driving gear 19 is provided on the output shaft of the motor 18, and a transmission gear 20 meshingly connected with the driving gear 19 is correspondingly provided on the driving rod 11. When in use, the motor 18 drives the driving gear 19 to rotate, and the driving gear 19 drives the transmission gear 20 to rotate, thereby driving the driving rod 11 fixedly connected to the transmission gear 20 to rotate, thereby realizing the adjustment function.

[0045] The terminal device can be a computer or a mobile phone.

[0046] like Figure 4 As shown, a protective cover 5 is provided on the base 1. By providing the protective cover 5, it can play the function of preventing rain and small animals, thereby effectively avoiding the occurrence of screw corrosion and phase-to-phase short circuit, effectively reducing the operation and maintenance workload of the operation and maintenance personnel, and greatly improving the safety and reliability of the line.

[0047] The side panels of the protective cover 5 are tilted outwards, and the protective cover 5 adopts a trapezoidal design, which can accelerate the speed of rainwater sliding down to a greater extent and avoid water accumulation.

[0048] Preferably, the inclination angle of the side plate can be 110°, which ensures that there is more space for the insulating operating rod to move without causing water accumulation and preventing the insulating operating rod from being stuck in the protective cover 5.

[0049] The material of the protective cover 5 can be a transparent insulating material, which can achieve the effect of phase insulation while not obstructing the operator's sight, thus ensuring the safety of the operators.

[0050] It is understandable that in order to keep the outer surface of the protective cover 5 smooth for a long time and reduce the points of force, the outer surface of the protective cover 5 can be mechanically polished and sprayed with polyester lubricant to prevent small animals from climbing on the protective cover 5, thereby reducing phase-to-phase short circuit faults.

[0051] Specifically, the first movable piece 7 and the second movable piece 6 are both provided with a U-shaped notch 16 for inserting the spring screw 10 ; the first movable piece 7 and the second movable piece 6 can be made of iron.

[0052] The insulator 2 may be a silicone insulator 2 .

[0053] The live adjustable isolating switch can be remotely controlled and adjusted on the ground using an insulating operating rod or a mobile phone. The heating defect of the isolating switch blade can be handled without shutting down the line or dispatching a large live working vehicle, which can greatly reduce the number of high-altitude operations of operation and maintenance personnel and further ensure personnel safety. At the same time, by providing a protective cover 5, the rainproof and small animal-proof capabilities of the isolating switch can be effectively enhanced, thereby reducing the number of line discharges or phase-to-phase short circuits and improving power supply reliability.

[0054] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
