Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0040] Figure 1 is a structural schematic diagram of an isolating switch provided by an embodiment of the present invention, Figure 2 is a partial structural schematic diagram of an anti-malfunction device of an isolating switch provided in an embodiment of the present invention, Figure 3 is a partial structural diagram of another anti-malfunction device of an isolating switch provided by an embodiment of the present invention, Figure 4 This is a schematic diagram of a structural block diagram of an isolating switch anti-malfunction device provided by an embodiment of the present invention, combined with Figure 1-Figure 4 As shown, this embodiment is suitable for preventing the disconnector from malfunctioning during the process of the construction personnel modifying the circuit of the busbar side disconnector.

[0041] like Figure 1 As shown, the isolating switch includes an isolating switch body 1 and a transmission shaft 2. Figure 2-Figure 4As shown, the anti-malfunction device of the isolating switch includes: a hydraulic column 8, a motor module 20, a sensor module 10, a processing module 19 and a short-circuit module 6, and the short-circuit module 6 includes an electric slide resistance (not shown in the figure); one end of the hydraulic column 8 is connected to the motor module 20, and the other end is connected to the sensor module 10, and is used to move toward the drive shaft 2 of the isolating switch under the drive of the motor module 20; the sensor module 10 is communicatively connected to the processing module 19, and is used to output a first sensing signal to the processing module 19 when it contacts the drive shaft 2 of the isolating switch, and output a second sensing signal to the processing module 19 when it senses the rotation of the drive shaft 2; the processing module 19 is also communicatively connected to the motor module 20 and the short-circuit module 6, and is used to output a stop motion signal to the motor module 20 according to the first sensing signal, so that the motor module 20 stops driving the hydraulic column 8, and is also used to output a resistance adjustment signal to the short-circuit module 6 according to the second sensing signal, so as to adjust the resistance of the electric slide resistance so that the short-circuit module 6 short-circuits the power supply of the drive shaft 2.

[0042] Exemplarily, when the isolating switch anti-maloperation device starts to work, the isolating switch anti-maloperation device starts to automatically locate the position of the transmission shaft 2. The hydraulic column 8 starts to extend under the drive of the motor module 20. The sensor module 10 connected to the hydraulic column 8 has a pressure sensing function. After the sensor module 10 contacts the transmission shaft 2, the sensor module 10 senses the pressure of the isolating switch transmission shaft 2, thereby locating the anti-maloperation device to the position of the transmission shaft 2. The sensor module 10 outputs the sensing signal to the processing module 19, and the processing module 19 sends an instruction to the motor module 20, and the motor module 20 stops driving the hydraulic column 8 to extend. At this time, the isolating switch anti-maloperation device completes the initial layout, and the sensor module 10 starts to detect the movement of the isolating switch transmission shaft 2. The construction personnel start working. If the construction personnel mistakenly connect the circuit, the isolating switch will malfunction. When the isolating switch transmission shaft 2 starts to rotate, the processing module 19 receives the sensing signal of the induction sheet module 10 and sends a command to the short-circuit module 6. The short-circuit module 6 is connected to the circuit of the motor power supply of the transmission shaft 2, which includes an electric slide and a quick connector. The electric slide can change the resistance value according to the input signal, and the quick connector can make the short-circuit module 6 quickly short-circuit after receiving the command. After the short-circuit module 6 receives the command, the resistance value of the electric slide is reset to zero, and the circuit is short-circuited, so that the motor power supply of the transmission shaft 2 is disconnected. The isolating switch transmission shaft 2 has no power supply and naturally cannot continue to rotate, thereby preventing the isolating switch from malfunctioning.

[0043] The embodiment of the present invention provides an anti-misoperation device for the isolating switch, which senses the movement of the transmission shaft of the isolating switch through the induction sheet module, and when the rotation of the transmission shaft is sensed, the motor power supply of the transmission shaft is disconnected through the short-circuit module, and the power supply of the transmission shaft is cut off to prevent the isolating switch from misoperating, thereby ensuring the safety of the construction personnel. In addition, since the short-circuit of the motor power supply of the isolating switch transmission shaft is performed by the short-circuit module, and the short-circuit module is directly connected in parallel to the circuit of the motor power supply of the isolating switch transmission shaft, the motor circuit of the isolating switch does not need to be rewired and the steps of secondary verification of the circuit are omitted after the construction is completed, thereby eliminating the need for additional operations.

[0044] Optionally, the anti-malfunction device may further include a DC power supply, and the processing module 19 may be a single-chip microcomputer. The DC power supply uses a DC 12V power supply to power the motor module 20, and the DC power supply uses a 3.3V power supply to power the single-chip microcomputer. The anti-malfunction device may further include a power switch, which is used to control the on and off of the power supply.

[0045] Optional, continue to refer to Figure 2-Figure 4 As shown, the processing module 19 can also be used to output a motion signal to the motor module 20 according to the second sensing signal, so that the motor module 20 continues to drive the hydraulic column 8 to move toward the isolating switch transmission shaft 2, so that the sensor plate module 10 applies rotational resistance to the transmission shaft 2.

[0046] Specifically, when the sensing sheet module 10 senses the rotation of the transmission shaft 2 , the processing module 19 receives the sensing signal of the sensing sheet module 10 , and the processing module 19 sends a command to the sensing sheet module 10 , and the sensing sheet module 10 applies pressure to the isolation switch transmission shaft 2 .

[0047] For example, after the induction sheet module 10 senses the rotation of the transmission shaft 2, the induction sheet module 10 will slowly apply pressure to the isolating switch transmission shaft 2 to increase the friction between the induction sheet module 10 and the transmission shaft 2, slowing down the rotation speed of the transmission shaft 2, and leaving enough time for the short-circuit module 6 to short-circuit the motor power supply of the isolating switch. This prevents the transmission shaft 2 from rotating quickly, causing the grounding knife switch to act quickly before the short-circuit module 6 short-circuits, threatening personnel safety.

[0048] Optional, continue to refer to Figure 4 As shown, the isolating switch anti-maloperation device can also include an alarm module 17; the sensor module 10 is also used to output the pressure information between the sensor module 10 and the transmission shaft 2 to the processing module 19 in real time; the processing module 19 is also communicated with the alarm module 17, and is used to control the alarm module 17 to alarm when the pressure information is greater than the preset pressure information.

[0049] The preset pressure information is a pre-set value used to determine whether the pressure between the sensor module 10 and the drive shaft 2 is within an abnormal range. When the isolating switch anti-malfunction device is in working condition, the pressure between the sensor module 10 and the drive shaft 2 may fluctuate within a small range due to various factors. After the sensor module 10 senses the rotation of the drive shaft 2, the sensor module 10 applies pressure to the isolating switch drive shaft 2. At this time, its pressure suddenly increases, which is much greater than the pressure when the sensor module 10 does not apply pressure. Therefore, the isolating switch anti-malfunction device requires a preset pressure information to determine whether the sensor module 10 applies pressure to the isolating switch drive shaft 2 to avoid misjudgment due to small range fluctuations in pressure.

[0050] For example, the isolating switch anti-malfunction device monitors the pressure information between the induction plate module 10 and the transmission shaft 2 in real time. When the pressure suddenly increases and exceeds the preset pressure information, the device determines that the induction plate module 10 has applied pressure to the isolating switch transmission shaft 2, that is, the transmission shaft 2 rotates. At this time, the processing module 19 controls the alarm module 17 to alarm to remind the construction personnel that the isolating switch has malfunctioned.

[0051] Optional, continue to refer to Figure 4 As shown, the anti-maloperation device can also include a sensing module 21 and an alarm module 17; the sensing module 21 is used to detect the distance information between the sensing module 21 and the human body; the processing module 19 is respectively communicated with the sensing module 21 and the alarm module 17, and is used to control the alarm module 17 to alarm when the distance information is less than the preset distance information.

[0052] The preset distance information is a pre-set value used to determine whether the distance between the human body and the sensing module is too close. Exemplarily, the sensing module 21 can emit and receive infrared lasers to detect the actual distance information between the sensing module 21 and the human body and send the actual distance information to the processing module 19. The processing module 19 makes a judgment based on the received actual distance information and the preset distance information preset in advance. When it is determined that the actual distance information is less than the preset distance information, it sends an alarm control information to the alarm module 17 to control the alarm module 17 to sound an alarm, reminding the approaching personnel that the grounding knife switch is energized and not to approach. Optionally, the processing module 19 can be a single-chip microcomputer, and the sensing module 21 sends the actual distance information of the human body to the single-chip microcomputer. When the single-chip microcomputer determines that the actual distance information is less than the preset distance information, it sends an alarm control information to the alarm module 17.

[0053] Optionally, the sensing module 21 may further include a sensitivity adjustment knob for adjusting the sensitivity of the sensing module 21 , so that the sensing module 21 can control the sensing accuracy of the sensing distance according to the actual application scenario, providing greater flexibility in actual operation.

[0054] Optional, continue to refer to Figure 4 As shown, the anti-malfunction device can also include a mechanical locking buckle 15; the processing module 19 is communicatively connected with the mechanical locking buckle 15, and is used to output a buckle pop-up signal to the mechanical locking buckle 15 when the anti-malfunction device is working, so as to control the mechanical locking buckle 15 to pop out and clamp the hand-cranked hole.

[0055] For example, when the isolating switch anti-maloperation device starts to work, the processing module 19 will automatically output a buckle pop-up signal to the mechanical locking buckle 15, and the mechanical locking buckle 15 will pop up and lock the hand-crank hole to prevent personnel from operating incorrectly and threatening personnel safety.

[0056] Optional, reference Figure 2 and Figure 3 As shown, the anti-malfunction device may further include a male module 3 and a female module 11, and the motor module 20 and the processing module 19 are both arranged in the male module 3. When the anti-malfunction device is working, the male module 3 and the female module 11 are arranged on two opposite sides of the transmission shaft 2. The female module 11 is provided with a hydraulic column positioning hole 12 for fixing the hydraulic column 8.

[0057] For example, reference Figure 1 The male module 3 and the female module 11 are placed opposite to each other, and the hydraulic columns 8 are located on both sides of the isolating switch transmission shaft 2. As the hydraulic column 8 extends, the hydraulic column 8 finally enters the hydraulic column positioning hole 12, making the overall structure more stable, the sensor module 10 is less susceptible to external influences, and the output sensing signal is more accurate.

[0058] Optionally, the hydraulic column 8 may include a primary hydraulic mechanism column and a secondary hydraulic mechanism column; one end of the primary hydraulic mechanism column is connected to the motor module 20, and the other end is connected to the induction plate module 10, and is used to move toward the isolating switch transmission shaft 2 under the drive of the motor module 20; the secondary hydraulic mechanism column is nested in the primary hydraulic mechanism column, and is used to move to the hydraulic column positioning hole 12 after the primary hydraulic mechanism column stops moving.

[0059] Continue to refer Figure 3 and Figure 4 As shown, after the anti-maloperation device of the outdoor disconnect switch starts working, the first-level hydraulic mechanism column extends to drive the sensor plate module 10 to move. When the sensor plate module 10 hits the transmission shaft 2, the processing module 19 receives the sensing signal of the sensor plate module 10 and sends a command to the motor module 20. The first-level hydraulic mechanism column stops extending, and the second-level hydraulic mechanism column extends to the hydraulic column positioning hole 12 on the mother module 11.

[0060] The structure of the primary hydraulic mechanism column and the secondary hydraulic mechanism column can make the installation position of the disconnector anti-malfunction device more flexible. The extension distance of the primary hydraulic mechanism column depends on the distance of the transmission shaft 2 relative to the primary hydraulic mechanism column. If the female module 11 cannot be installed at a position that allows the primary hydraulic mechanism column to be extended to the hydraulic column positioning hole 12, the secondary hydraulic mechanism column can be further extended, so that the hydraulic column 8 is extended to the hydraulic column positioning hole 12 on the female module 11. The structure of the primary hydraulic mechanism column and the secondary hydraulic mechanism column allows the disconnector anti-malfunction device to flexibly set the installation position of the male module 3 and the female module 11 according to the actual construction environment. In actual construction, the disconnector anti-malfunction device can adjust the extension distance of the hydraulic column 8 according to the relative positions of the transmission shaft 2, the male module 3 and the female module 11, so that the disconnector anti-malfunction device can be suitable for different construction environments.

[0061] Optional, continue to refer to Figure 2 , Figure 3 and Figure 4 As shown, the anti-malfunction device may also include a male module 3, in which the motor module 20 and the processing module 19 are both arranged. The anti-malfunction device also includes a power module 18 arranged in the male module 3, and the power module 18 is used to supply power to the processing module 19 and the motor module 20. The anti-malfunction device directly supplies power to the processing module 19 and the motor module 20 through the power module 18 arranged in the male module 3, and no external power supply is required during the working process, the working independence is high, and the power supply method is simple and stable. In addition, the power module 18, the motor module 20 and the processing module 19 are all arranged in the male module 3, so that the anti-malfunction device has stronger reliability and provides physical protection for each module.

[0062] Optional, continue to refer to Figure 2 , Figure 3 and Figure 4 As shown, the anti-malfunction device also includes a female module 11, and the female module 11 includes a charging module 14 and a power supply battery; when the anti-malfunction device stops working, the male module 3 and the female module 11 are configured to be connected; the charging module 14 is used to charge the power supply module 18, or the power supply battery is used to charge the power supply module 18.

[0063] Exemplarily, the female module 11 is equipped with a large-capacity power supply battery and a 220kV charging module for charging the power module 18. The male module 3 and the female module 11 are combined together when the anti-malfunction device of the outdoor disconnector is not working, and the charging module in the female module 11 charges the power module 18 in the male module 3. The male module 3 and the female module 11 of the anti-malfunction device can be combined together for easy storage and transportation. In addition, when the anti-malfunction device is not working, the power module 18 in the male module 3 can be charged through the female module 11, so that the power module 18 of the anti-malfunction device has sufficient power at any time to cope with emergencies.

[0064] Optional, continue to refer to Figure 2 and Figure 4 As shown, the anti-malfunction device also includes a button module 5 and a display module 4 arranged on the surface of the male module 3; the button module 5 is configured to turn on the anti-malfunction device; and the display module 4 is used to display the remaining power of the power module 18.

[0065] refer to Figure 2 The display module 4 displays the power level of the power module 18. The display module 18 facilitates the user to monitor the power level of the anti-malfunction device at any time to avoid power failure during use.

[0066] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
