[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 8As shown, an embodiment of the present invention provides an insulating operating rod, which includes an operating head 10, a telescopic assembly 20, a current detecting member 30, a controller 40 and a handle 50, wherein the operating head 10 has a receiving cavity 11, and one end of the operating head 10 has an opening 12 connected to the receiving cavity 11, and the telescopic assembly 20 includes a driving mechanism 21 and a moving member 22, and the driving mechanism 21 and the moving member 22 are both arranged in the receiving cavity 11, and the moving member 22 has a storage state in which the moving member 22 is stored in the receiving cavity 11 and a protruding state in which the second end of the moving member 22 protrudes to the outside of the opening 12 The driving mechanism 21 is connected to the first end of the moving member 22 to switch the moving member 22 between the retracted state and the extended state. The current detecting member 30 is arranged on the moving member 22. The controller 40 is arranged on the operating head 10 and is connected to the current detecting member 30 and the driving mechanism 21 by signals. When the current detecting member 30 detects that the knife switch has current, the controller 40 controls the driving mechanism 21 according to the detection signal of the current detecting member 30, so that the driving mechanism 21 drives the moving member 22 to remain in the retracted state. One end of the handle 50 is detachably connected to the operating head 10.

[0035] The insulating operating rod provided in this embodiment is used, and the insulating operating rod includes an operating head 10, a telescopic component 20, a current detection component 30, a controller 40 and a handle 50. The operating head 10 has a accommodating cavity 11, and an opening 12 is provided at one end of the operating head 10, and the opening 12 is communicated with the accommodating cavity 11. The driving mechanism 21 and the moving part 22 of the telescopic component 20 are both arranged in the accommodating cavity 11. The moving part 22 has a storage state and an extended state. The driving mechanism 21 is drivingly connected to the first end of the moving part 22, so that the moving part 22 can be switched between the storage state and the extended state under the action of the driving mechanism 21. The current detection component 30 is arranged on the moving part 22, and a controller 40 is arranged in the accommodating cavity 11. The controller 40 can respectively connect signals with the current detection component 30 and the driving mechanism 21. Specifically, the staff operates the handle 50 to drive the operating head 10 to move into the pull ring of the knife switch, and the current detection member 30 can detect the current of the knife switch. When the current detection member 30 detects that there is current on the knife switch, the controller 40 controls the driving mechanism 21 to drive the moving member 22 to remain in the storage state according to the detection signal of the current detection member 30. If the current detection member 30 detects that there is no current on the knife switch, the driving mechanism 21 drives the moving member 22 to switch from the storage state to the extended state, so that the moving member 22 passes through the opening 12 on the operating head 10 and passes through the accommodating cavity 11. , and then use the moving part 22 to extend and drive the knife switch to perform the disconnect operation, so that the staff can avoid operating the knife switch when it is energized. When the knife switch is energized, the moving part 22 is always in the storage state, so that the moving part 22 is stored in the accommodating chamber 11. When the knife switch is not energized, the moving part 22 is switched from the storage state to the extended state under the action of the driving mechanism 21. This makes it easy to use the moving part 22 to drive the knife switch to operate, which can avoid the knife switch of the disconnector from generating an arc, avoid safety accidents, and improve the practicality and structural reliability of the insulating operating rod.

[0036] It should be noted that when the movable member 22 is in the retracted state, it will not extend, and will remain in the retracted state. When the movable member 22 is in the extended state, if the knife switch is powered, it will retract to the retracted state.

[0037] like Figures 1 to 4As shown, the driving mechanism 21 includes a pushing driving mechanism 211 and an elastic member 212. The pushing driving mechanism 211 drives the moving member 22 to switch from the storage state to the extended state. The elastic member 212 is sleeved on the moving member 22. The first end of the elastic member 212 abuts against the operating head 10, and the second end of the elastic member 212 abuts against the moving member 22. When the moving member 22 is in the extended state, the elastic member 212 is in a compressed state. The elastic member 212 can drive the moving member 22 to switch from the extended state to the storage state. By adopting the above structure, the push drive mechanism 211 can drive the movable member 22 to switch from the storage state to the extended state, and an elastic member 212 is sleeved on the movable member 22. Since the first end of the elastic member 212 abuts against the operating head 10, and the second end of the elastic member 212 abuts against the movable member 22, when the movable member 22 passes through the opening 12 and switches from the storage state to the extended state, the elastic member 212 is compressed and is in a compressed state, ensuring that when the knife switch is suddenly powered off, the push drive mechanism 211 does not drive the movable member 22 to extend, and relies on the compression elastic force of the elastic member 212 to ensure that the movable member 22 can be reset from the extended state to the storage state, so that it is convenient to use the current detection member 30 to detect whether there is current on the knife switch, and it is convenient for the operator to identify it.

[0038] like Figures 1 to 4 as well as Figure 7 As shown, the drive mechanism 21 also includes a position relay 213, which is arranged on the operating head 10. The position relay 213 has a driving part and a card block 2131. The driving part is arranged on the operating head 10, and the card block 2131 is movably penetrated on the operating head 10. The driving part is drivingly connected to the card block 2131. When the moving member 22 is in the extended state, the card block 2131 extends into the accommodating chamber 11 and locks with the moving member 22 to keep the moving member 22 in the extended state; when the moving member 22 is in the extended state and the current detection member 30 detects that the knife switch has current, the controller 40 controls the card block 2131 to unlock the moving member 22 according to the detection signal of the current detection member 30, so that the elastic member 212 drives the moving member 22 to switch from the extended state to the retracted state. With the above structure, a position relay 213 is provided on the operating head 10, and the driving part of the position relay 213 can drive the card block 2131 to be penetrated on the operating head 10, so that when the moving part 22 is in the extended state, the driving part drives the card block 2131 to extend into the accommodating cavity 11 and lock with the moving part 22, so that the card block 2131 can play a locking role to avoid being reset by the elastic part 212. If the moving part 22 is in the extended state and the current detection part 30 detects that there is current in the knife switch, the controller 40 controls the card block 2131 to unlock the moving part 22 according to the detection signal of the current detection part 30, so that the moving part 22 can be reset under the action of the elastic part 212, so that the moving part 22 is switched from the extended state to the retracted state.

[0039] In this embodiment, the current detection element 30 is a Hall element. With the above structure, the Hall element is used to detect the current on the knife switch.

[0040] In this embodiment, there are multiple current detection members 30, and the multiple current detection members 30 are arranged at intervals along the length direction of the moving member 22. With the above structure, by arranging multiple current detection members 30 at intervals along the length direction of the moving member 22, it is convenient for the operator to extend the moving member 22 into the pull ring on the knife switch when the moving member 22 is in the extended state, and the multiple current detection members 30 can be used for current detection, thereby improving the practicality and structural reliability of the insulating operating rod.

[0041] like Figures 1 to 4 As shown, the moving member 22 includes a moving rod 221, a first fixed block 222 is fixedly provided on the moving rod 221, a second fixed block 13 is fixedly provided at a position close to the opening 12 of the accommodating chamber 11, the second end of the moving rod 221 is passed through the second fixed block 13, the elastic member 212 is sleeved on the moving rod 221, the first end of the elastic member 212 is connected to the first fixed block 222, the second end of the elastic member 212 is abutted against the second fixed block 13, and when the moving member 22 is in an extended state, the blocking block 2131 is abutted against the first fixed block 222. With the above structure, a first fixed block 222 is fixedly provided on the moving rod 221, and a second fixed block 13 is fixedly provided at a position close to the opening 12 of the accommodating chamber 11. The first end of the elastic member 212 is connected to the first fixed block 222, and the second end of the elastic member 212 abuts against the second fixed block 13, so that it is convenient to use the elastic member 212 to reset the moving rod 221, and when the moving member 22 is in the extended state, the blocking block 2131 abuts against the first fixed block 222, so that it is convenient to ensure that the moving member 22 is in the extended state.

[0042] As shown in the present embodiment, the telescopic assembly 20 further includes a transmission member 23, which includes a rotating cam 231 and a connecting rod 232. The rotating cam 231 is rotatably disposed in the accommodating chamber 11, the first end of the connecting rod 232 is hinged to the rotating cam 231, and the second end of the connecting rod 232 is hinged to the first end of the moving member 22. With the transmission member 23 of the above structure, the rotating cam 231 can rotate in the accommodating chamber 11, the first end of the connecting rod 232 is hinged to the rotating cam 231, and the second end of the connecting rod 232 is hinged to the first end of the moving member 22, and then when the rotating cam 231 rotates, the moving member 22 can be controlled to switch between the extended state and the stored state under the action of the connecting rod 232.

[0043] like Figure 4 and Figure 5As shown, the driving mechanism 211 includes a driving motor 2111 and a driving gear 2112, the driving motor 2111 is drivingly connected to the driving gear 2112, a transmission gear 233 and a rotating column 234 are provided on the rotating cam 231, the rotating column 234 is sequentially arranged in the transmission gear 233 and the rotating cam 231, and the driving gear 2112 is meshed with the transmission gear 233 to drive the rotating cam 231 to rotate. The driving motor 2111 can control the driving gear 2112 to rotate, and the rotating column 234 is sequentially arranged in the transmission gear 233 and the rotating cam 231, so that when the driving gear 2112 drives the transmission gear 233 to mesh and transmit, the transmission gear 233 rotates to drive the rotating column 234 to rotate, and the rotating column 234 rotates to drive the rotating cam 231 to rotate, so as to facilitate driving the rotating cam 231 to rotate and thus switching the moving member 22 between the extended state and the retracted state.

[0044] like Figures 1 to 4 As shown, the insulating operating rod also includes a first limit switch 61 and a second limit switch 62, and the first limit switch 61 and the second limit switch 62 are both arranged in the accommodating cavity 11, and the first limit switch 61 and the second limit switch 62 are arranged at intervals, and the first limit switch 61 is located between the opening 12 and the second limit switch 62. When the movable member 22 is in an extended state, the rotating cam 231 abuts against the first limit switch 61, and the first limit switch 61 and the position relay 213 are both connected to the controller 40 signal so that the block 2131 extends into the accommodating cavity 11 and abuts against the movable member 22. When the movable member 22 is in a retracted state, the rotating cam 231 abuts against the second limit switch 62, and the second limit switch 62 is connected to the drive mechanism 21 signal to control the drive mechanism 21 to stop running. With the above structure, the first limit switch 61 and the second limit switch 62 are arranged at intervals, and the first limit switch 61 is located between the opening 12 and the second limit switch 62. When the moving member 22 is in the extended state, the rotating cam 231 abuts against the first limit switch 61, so that the first limit switch 61 transmits a signal to the controller 40, and the controller controls the driving motor 2111 to stop running. At this time, the block 2131 of the position relay 213 extends into the accommodating cavity 11 and abuts against the first fixed block 222, thereby preventing the moving member 22 from being in the extended state. 22 is reset under the action of the elastic member 212. When the current detection member 30 detects the current, the current detection member 30 transmits the signal to the controller 40. The controller 40 controls the driving part of the position relay 213 to drive the block 2131 to shrink and move out of the accommodating chamber 11. The movable member 22 is reset by the elastic member 212. At this time, the movable member 22 drives the rotating cam 231 to abut against the second limit switch 62 through the connecting rod 232. In this way, the driving mechanism 21 can be controlled to stop running, so that the movable member 22 can be kept in the storage state.

[0045] like Figure 8As shown, the handle 50 includes a connecting rod and a gripping portion 52, the connecting rod is connected to the gripping portion 52, an external thread is provided on the operating head 10, one end of the connecting rod is provided with an internal thread, and the external thread is connected to the internal thread. The handle 50 with the above structure is provided with an external thread on the operating head 10, one end of the connecting rod is provided with an internal thread, and the external thread is connected to the internal thread, so that the connecting rod is conveniently threadedly connected to the operating head 10, so as to realize a detachable connection between the operating head 10 and the handle 50, and the disassembly method is convenient.

[0046] It should be noted that a reset switch and a display screen are provided on the gripping portion 52. The display screen can display the current size in real time. When the movable member 22 needs to be operated, the reset switch can perform a reset operation so that the movable member 22 switches to the storage state.

[0047] Another embodiment of the present invention provides an operating method of an isolating switch. The operating method of the isolating switch is implemented by the insulating operating rod provided above. The operating method of the isolating switch includes:

[0048] Place the insulating operating rod close to the pull ring of the knife switch of the isolating switch, and obtain a first current value on the pull ring through the current detection member 30 of the insulating operating rod;

[0049] The first current value detected by the current detection member 30 is compared with the preset current value. If the first current value is greater than the preset current value, the moving member 22 is placed in the storage state. If the first current value is less than the preset current value, the moving member 22 of the insulating operating rod is extended to open the pull ring through the moving member 22.

[0050] In the step of extending the moving member 22 of the insulating operating rod, the second current value on the pull ring is detected by the current detecting member 30;

[0051] If the second current value is greater than the preset current value, the moving member 22 switches from the extended state to the retracted state. If the second current value is less than the preset current value, the moving member 22 remains in the extended state.

[0052] By adopting the above steps, the insulating operating rod approaches the pull ring of the knife switch of the isolating switch, obtains the first current value on the pull ring through the current detection member 30, compares the first current value with the preset current value, and if the first current value is greater than the preset current value, the moving member 22 is in the storage state, which is convenient for the operator to observe whether the pull ring is charged. If the first current value is less than the preset current value, the moving member 22 of the insulating operating rod is extended to open the pull ring through the moving member 22. When the moving member 22 is extended, if the pull ring is charged, and the current detection member 30 on the moving member 22 detects the second current value in real time, if the second current value is greater than the preset current value, the moving member 22 is switched from the extended state to the stored state, which can avoid the sudden power supply when the moving member 22 is gradually extended, causing the knife switch to be operated with load, and avoid dangerous accidents. If the second current value is less than the preset current value, the moving member 22 remains in the extended state, and then the insulating operating rod is used to realize the operation of pulling the knife switch.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0055] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0056] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
