Description

Technical Field

[0001] This invention relates to the field of power system technology, and in particular to a device for preventing accidental operation of a disconnecting switch. Background Technology

[0002] In recent years, substation expansion and renovation projects have been increasing. These projects often require modifications to operating equipment. Among the operating equipment, the modification of the bus-side disconnector circuit is the most dangerous. If, during the circuit modification process, construction workers accidentally connect the circuit, the disconnector will malfunction and close directly with the grounding switch on.

[0003] Currently, there are two main technical methods: 1. Have construction workers disconnect the motor circuit circuit breaker before starting work. However, this method cannot ensure safety during the acceptance of the disconnect switch after circuit modification, and it is impossible to control the entire work process; 2. Disconnect the motor circuit of the busbar side disconnect switch. Although this can effectively ensure that the disconnect switch is not easily operated accidentally during construction, it increases the steps of subsequent rewiring and acceptance of the secondary circuit.

[0008] The processing module is also communicatively connected to the motor module and the jumper module. It is used to output a stop motion signal to the motor module based on the first sensing signal so that the motor module stops driving the hydraulic cylinder. It is also used to output a resistance adjustment signal to the jumper module based on the second sensing signal so that the resistance of the electric sliding resistor is adjusted so that the jumper module short-circuits the power supply of the drive shaft.

[0009] Optionally, the processing module is also used to output a motion signal to the motor module based on the second sensing signal, so that the motor module continues to drive the isolation column toward the drive shaft, so that the sensing plate module applies rotational resistance to the drive shaft.

[0014] The sensing module is used to detect the distance between the sensing module and the human body;

[0015] The processing module is connected to both the sensing module and the alarm module, and is used to control the alarm module to sound an alarm when the distance information is less than the preset distance information.

[0016] Optionally, the anti-misoperation device may also include a mechanical locking latch;

[0017] The processing module is connected to the mechanical locking latch in communication. When the anti-misoperation device is working, it outputs a latch pop-out signal to the mechanical locking latch to control the mechanical locking latch to pop out and lock the hand crank hole.

[0018] Optionally, the anti-maloperation device also includes a male module and a female module, with the motor module and processing module both located in the male module;

[0019] When the anti-maloperation device is working, the male module and the female module are arranged on opposite sides of the drive shaft; the female module is provided with hydraulic column positioning holes for fixing the hydraulic column.

[0020] Optionally, the hydraulic column includes a primary hydraulic mechanism column and a secondary hydraulic mechanism column;

[0021] One end of the primary hydraulic mechanism column is connected to the motor module, and the other end is connected to the induction plate module, which is used to move towards the transmission shaft under the drive of the motor module;

[0022] The secondary hydraulic mechanism column is nested within the primary hydraulic mechanism column and is used to move into the positioning hole of the hydraulic column after the primary hydraulic mechanism column stops moving.

[0023] Optionally, the anti-maloperation device also includes a common module, in which both the motor module and the processing module are located;

[0031] The anti-misoperation device for disconnecting switches provided in this embodiment of the invention uses an induction module to sense the movement of the disconnecting switch's drive shaft, enabling real-time monitoring of whether the disconnecting switch will maloperate. If rotation of the disconnecting switch's drive shaft is sensed, the motor power supply of the disconnecting switch is directly short-circuited to prevent maloperation, ensuring that the grounding switch will not close and guaranteeing the safety of construction personnel. Furthermore, the anti-misoperation device for disconnecting switches provided in this embodiment of the invention controls the electric sliding resistor to short-circuit the motor power supply of the disconnecting switch. While ensuring that the disconnecting switch will not maloperate during construction, it does not alter the circuit structure of the motor power supply of the disconnecting switch, requiring no additional operations or acceptance procedures, and eliminating the need for subsequent rewiring and secondary acceptance circuit steps.

Figure 2 This is a partial structural schematic diagram of an anti-maloperation device for a disconnecting switch provided in an embodiment of the present invention. Figure 3 This is a partial structural schematic diagram of another anti-maloperation device for a disconnecting switch provided in an embodiment of the present invention. Figure 4 This is a schematic structural block diagram of a disconnector switch anti-maloperation device provided in an embodiment of the present invention, combined with... Figures 1-4 As shown, this embodiment is applicable to preventing accidental operation of the disconnecting switch during the process of circuit modification of the busbar-side disconnecting switch by construction personnel.

[0041] like Figure 1 As shown, the disconnecting switch includes a disconnecting switch body 1 and a drive shaft 2, as follows: Figures 2-4As shown, the anti-maloperation device of the disconnecting switch includes: a hydraulic column 8, a motor module 20, an induction plate module 10, a processing module 19, and a shorting wire module 6. The shorting wire module 6 includes an electric sliding resistor (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 induction plate module 10, for moving towards the drive shaft 2 of the disconnecting switch under the drive of the motor module 20. The induction plate module 10 is communicatively connected to the processing module 19, for outputting a first induction signal to the processing module 19 when in contact with the drive shaft 2 of the disconnecting switch, and outputting a second induction 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 shorting wire module 6, for outputting a stop movement signal to the motor module 20 according to the first induction signal, so that the motor module 20 stops driving the hydraulic column 8, and for outputting a resistance adjustment signal to the shorting wire module 6 according to the second induction signal, so as to adjust the resistance of the electric sliding resistor so that the shorting wire module 6 short-circuits the power supply of the drive shaft 2.

[0042] For example, when the anti-misoperation device for the disconnecting switch starts working, it automatically positions the drive shaft 2. The hydraulic column 8 extends under the drive of the motor module 20. The sensing plate module 10 connected to the hydraulic column 8 has a pressure sensing function. After the sensing plate module 10 contacts the drive shaft 2, it senses the pressure on the disconnecting switch drive shaft 2, thereby positioning the anti-misoperation device to the drive shaft 2. The sensing plate module 10 outputs a sensing signal to the processing module 19, which then sends a command to the motor module 20, causing the motor module 20 to stop extending the hydraulic column 8. At this point, the anti-misoperation device for the disconnecting switch completes its initial setup, and the sensing plate module 10 begins detecting the movement of the disconnecting switch drive shaft 2. Construction personnel begin work. If the construction personnel accidentally connect the circuit, the disconnecting switch will misoperate. When the disconnector switch drive shaft 2 starts to rotate, the processing module 19 receives the sensing signal from the sensing element module 10 and sends a command to the shorting wire module 6. The shorting wire module 6 is connected to the motor power supply circuit of the drive shaft 2 and includes an electric sliding resistor and a quick connector. The electric sliding resistor can change its resistance value according to the input signal, and the quick connector allows the shorting wire module 6 to quickly short-circuit after receiving the command. After receiving the command, the resistance value of the electric sliding resistor returns to zero, and the circuit is short-circuited, thus disconnecting the motor power supply of the drive shaft 2. Without power supply, the disconnector switch drive shaft 2 cannot continue to rotate, thereby preventing the disconnector switch from malfunctioning.

[0043] This invention provides an anti-misoperation device for a disconnecting switch. A sensing element module detects the movement of the disconnecting switch's drive shaft. Upon detecting rotation, a shorting wire module disconnects the motor power supply to the drive shaft, preventing accidental operation and ensuring the safety of construction personnel. Furthermore, since the shorting of the motor power supply to the disconnecting switch's drive shaft is performed by the shorting wire module, which is directly connected in parallel to the motor power supply circuit, the motor circuit of the disconnecting switch does not require rewiring or secondary circuit verification after construction, saving additional steps.

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

[0045] Optional, continue to refer to Figures 2-4 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 toward the disconnect switch drive shaft 2, so that the sensing plate module 10 applies rotational resistance to the drive shaft 2.

[0046] Specifically, when the sensing element module 10 senses the rotation of the drive shaft 2, the processing module 19 receives the sensing signal from the sensing element module 10 and sends a command to the sensing element module 10, which then applies pressure to the disconnect switch drive shaft 2.

[0047] For example, after the sensing element module 10 senses the rotation of the drive shaft 2, the sensing element module 10 slowly applies pressure to the disconnector switch drive shaft 2 to increase the friction between the sensing element module 10 and the drive shaft 2, thereby slowing down the rotation speed of the drive shaft 2 and allowing sufficient time for the short-circuit wire module 6 to short-circuit the motor power supply of the disconnector switch. This prevents the drive shaft 2 from rotating too quickly, which could cause the grounding switch to actuate rapidly before the short-circuit wire module 6 can short-circuit, thus threatening personnel safety.

[0048] Optional, continue to refer to Figure 4 As shown, the anti-maloperation device for the disconnect switch may also include an alarm module 17; the sensing plate module 10 is also used to output the pressure information between the sensing plate module 10 and the drive shaft 2 to the processing module 19 in real time; the processing module 19 is also connected to the alarm module 17 in communication and is used to control the alarm module 17 to sound an 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 sensing element module 10 and the drive shaft 2 is within an abnormal range. When the disconnector switch anti-maloperation device is in operation, the pressure between the sensing element module 10 and the drive shaft 2 may fluctuate within a small range due to various factors. After the sensing element module 10 senses the rotation of the drive shaft 2, it applies pressure to the disconnector switch drive shaft 2, at which point the pressure suddenly increases, far exceeding the pressure when the sensing element module 10 does not apply pressure. Therefore, the disconnector switch anti-maloperation device requires a preset pressure information to determine whether the sensing element module 10 has applied pressure to the disconnector switch drive shaft 2, avoiding misjudgments due to small pressure fluctuations.

[0050] For example, the anti-maloperation device for the disconnecting switch monitors the pressure information between the sensing element module 10 and the drive shaft 2 in real time. When the pressure suddenly increases beyond the preset pressure information, the device determines that the sensing element module 10 has applied pressure to the drive shaft 2 of the disconnecting switch, that is, the drive shaft 2 is rotating. At this time, the processing module 19 controls the alarm module 17 to sound an alarm to remind the construction personnel that the disconnecting switch has been maloperated.

[0051] Optional, continue to refer to Figure 4 As shown, the anti-malfunction device may 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 communicatively connected to the sensing module 21 and the alarm module 17 respectively, and is used to control the alarm module 17 to sound an 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. For example, the sensing module 21 can emit and receive infrared lasers to detect the actual distance between the sensing module 21 and the human body and send this actual distance information to the processing module 19. The processing module 19 judges based on the received actual distance information and the pre-set distance information. When it determines that the actual distance information is less than the preset distance information, it sends alarm control information to the alarm module 17 to control the alarm module 17 to issue an alarm, reminding the approaching personnel that the grounding switch is energized and not to approach. Optionally, the processing module 19 can be a microcontroller. The sensing module 21 sends the actual distance information of the human body to the microcontroller, and the microcontroller sends alarm control information to the alarm module 17 when it determines that the actual distance information is less than the preset distance information.

[0053] Optionally, the sensing module 21 may also 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-misoperation device may also include a mechanical locking buckle 15; the processing module 19 is communicatively connected to the mechanical locking buckle 15 and is used to output a buckle pop-out signal to the mechanical locking buckle 15 when the anti-misoperation device is working, so as to control the mechanical locking buckle 15 to pop out and lock the hand crank hole.

[0055] For example, when the anti-misoperation device of the disconnect switch starts to work, the processing module 19 will automatically output a latch pop-out signal to the mechanical locking latch 15. The mechanical locking latch 15 pops out and locks the hand crank hole to prevent personnel from misoperating and threatening personnel safety.

[0056] Optional, see reference Figure 2 and Figure 3 As shown, the anti-maloperation device may further include a male module 3 and a female module 11, with the motor module 20 and processing module 19 both housed in the male module 3. When the anti-maloperation device is in operation, the male module 3 and female module 11 are positioned on opposite sides of the drive shaft 2. The female module 11 is provided with hydraulic column positioning holes 12 for fixing the hydraulic column 8.

[0057] For example, refer to Figure 1 The male module 3 and the female module 11 are placed opposite each other, and the hydraulic columns 8 are located on both sides of the disconnector drive shaft 2, one above the other. As the hydraulic columns 8 extend, they eventually enter the hydraulic column positioning hole 12, making the overall structure more stable and the sensing plate module 10 less susceptible to external influences, and its output sensing signal 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 sensing plate module 10, and is used to move toward the disconnector drive 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 into the hydraulic column positioning hole 12 after the primary hydraulic mechanism column stops moving.

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

[0060] The structure of the primary and secondary hydraulic mechanism columns allows for greater flexibility in the installation position of the disconnector switch anti-maloperation device. The extension distance of the primary hydraulic mechanism column depends on the distance between the drive shaft 2 and the primary hydraulic mechanism column. If the female module 11 cannot be installed at the position where the primary hydraulic mechanism column extends to the hydraulic column positioning hole 12, the secondary hydraulic mechanism column can extend further, allowing the hydraulic column 8 to extend into the hydraulic column positioning hole 12 on the female module 11. This structure allows the disconnector switch anti-maloperation device to flexibly set the installation positions of the male module 3 and female module 11 according to the actual construction environment. In actual construction, the anti-maloperation device can adjust the extension distance of the hydraulic column 8 based on the relative positions of the drive shaft 2, male module 3, and female module 11, making it suitable for different construction environments.

[0061] Optional, continue to refer to Figure 2 , Figure 3 and Figure 4 As shown, the anti-maloperation device may further include a common module 3, in which the motor module 20 and processing module 19 are all housed. The anti-maloperation device also includes a power supply module 18 housed in the common module 3, which supplies power to the processing module 19 and motor module 20. The anti-maloperation device directly supplies power to the processing module 19 and motor module 20 via the power supply module 18 in the common module 3, eliminating the need for external power during operation, resulting in high operational independence and a simple and stable power supply method. Furthermore, the fact that the power supply module 18, motor module 20, and processing module 19 are all housed in the common module 3 enhances the reliability of the anti-maloperation device, providing physical protection for each module.

[0062] Optional, continue to refer to Figure 2 , Figure 3 and Figure 4 As shown, the anti-maloperation device also includes a mother module 11, which includes a charging module 14 and a power supply battery. When the anti-maloperation device stops working, the male module 3 and the mother 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] For example, the female module 11 is equipped with a high-capacity power supply battery and a 220kV charging module for charging the power module 18. The male module 3 and female module 11 are combined when the outdoor disconnect switch anti-maloperation device is not in operation, with the charging module in the female module 11 charging the power module 18 in the male module 3. The male module 3 and female module 11 of the anti-maloperation device can be combined for easy storage and transportation. Furthermore, when the anti-maloperation device is not in operation, the female module 11 can charge the power module 18 in the male module 3, ensuring that the power module 18 of the anti-maloperation device always has sufficient power to cope with emergencies.

[0064] Optional, continue to refer to Figure 2 and Figure 4 As shown, the anti-maloperation device also includes a button module 5 and a display module 4 disposed on the surface of the power module 3; the button module 5 is configured to turn on the anti-maloperation device; 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, allowing users to monitor the power level of the anti-malfunction device at any time and avoid power outages during use.

[0066] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
