Description

Technical Field

[0001] This invention relates to the field of substation disconnect switch technology, specifically to a substation disconnect switch operating mechanism with anti-accidental contact function. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power sources, switching operations, and connecting and disconnecting small-current circuits, without arc-extinguishing functionality. When in the open position, the disconnecting switch has a specified insulation distance between its contacts and a clear disconnection mark; when in the closed position, it can carry current under normal circuit conditions and current under abnormal conditions for a specified time. It is generally used as a high-voltage disconnecting switch, i.e., a disconnecting switch with a rated voltage of 1kV or higher. While its working principle and structure are relatively simple, its widespread use and high reliability requirements significantly impact the design, construction, and safe operation of substations and power plants.

[0003] Disconnecting switches are primarily used to reliably isolate the energized parts of a high-voltage power distribution system from the energized parts, ensuring safety during maintenance. All contacts of a disconnecting switch are exposed to the air, with a clearly visible breaking point. Disconnecting switches lack arc-extinguishing devices and therefore cannot be used to interrupt load current or short-circuit current. Closing and opening operations of a disconnecting switch require an electric actuator to ensure successful operation.

[0004] When using the existing disconnect switch operating mechanism, the closing button on the control panel inside the control box is only a single button. After the control box door is opened, the operator is prone to accidentally touching the closing button, which increases the operational risk. At the same time, the existing operating mechanism lacks a protective device to shield the hand crank socket inside the control box, making it easy for the hand crank to be accidentally inserted and started, affecting circuit safety. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a substation disconnect switch operating mechanism with anti-accidental touch function. By setting a transparent cover, rod hole, anti-disengagement rotating rod and magnetic piece, the transparent cover covers the outside of the closing button. After the anti-disengagement rotating rod passes through the rod hole and rotates downward, the magnetic piece at the end of the anti-disengagement rotating rod is attracted to the operating panel. The transparent cover covers and protects the closing button, preventing the operator from accidentally touching the closing button, reducing the operation risk, and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a substation disconnect switch operating mechanism with anti-accidental contact function, comprising an operating box, a door connected to one side of the operating box via a hinge, a mortise lock positioned vertically on the side of the door away from the hinge, a latch baffle installed on the operating box corresponding to the mortise lock position, an operating panel mounted on the inner side of the operating box via a support crossbar, a closing button on the operating panel, a transparent cover on the outer side of the closing button, a rod hole with a center opening on the lower side of the transparent cover, an anti-disengagement rotating rod passing through the rod hole, and a magnet fixedly connected to one end of the anti-disengagement rotating rod.

[0007] Furthermore, a drive motor is installed inside the control box on the upper side of the control panel, and a reducer is connected to the output end of the drive motor. A hand crank slot is provided on the side of the reducer away from the drive motor.

[0008] Furthermore, a protective baffle is slidably connected to the control box corresponding to the hand crank slot, and a stop button is provided on one side of the closing button.

[0009] Furthermore, an opening button is provided on the upper side of the closing button, and a grounding knob is provided on one side of the opening button.

[0010] Furthermore, a transmission disc is connected to the output end of the reducer, and a handle is installed on the door between the two mortise locks.

[0011] Furthermore, a support conduit is fixedly connected to the lower side of the control box, the drive motor is bolted to the control box, and the reducer is bolted to the drive motor housing.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the design of a transparent cover, a rod hole, an anti-detachment rotating rod, and a magnetic piece, allows the transparent cover to cover the outside of the closing button, and the anti-detachment rotating rod to rotate downward after passing through the rod hole, causing the magnetic piece at the end of the anti-detachment rotating rod to adhere to the operation panel, so that the transparent cover covers and protects the closing button, preventing the operator from accidentally touching the closing button and reducing the operational risk. 2. The invention uses a protective baffle to slide the baffle to the front of the hand crank slot when not in use, thus protecting the hand crank slot and preventing accidental insertion into the hand crank slot to start the transmission plate, thereby ensuring circuit safety.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-4 This embodiment provides a technical solution: a substation disconnect switch operating mechanism with anti-accidental contact function, including an operating box 2. One side of the operating box 2 is connected to a door 3 via a hinge. A mortise lock 4 is provided at the upper and lower positions on the side of the door 3 away from the hinge. A lock tongue baffle 19 is installed on the operating box 2 corresponding to the mortise lock 4. An operating panel 18 is installed on the inner side of the operating box 2 via a support crossbar. A closing button 13 is provided on the operating panel 18. A transparent cover 14 is provided on the outer side of the closing button 13. A rod hole 17 is opened at the center of the lower side of the transparent cover 14. An anti-detachment rotating rod 15 passes through the rod hole 17. A magnet 16 is fixedly connected to one end of the anti-detachment rotating rod 15.

[0017] like Figure 1-4As shown, when it is necessary to operate and adjust the disconnect switch, insert the key into the mortise lock 4 to open the mortise lock 4, thereby opening the box door 3. Then, operate and adjust using the buttons on the operation panel 18. After pressing the closing button 13 and the opening button 11, the drive motor 7 drives the transmission disc 5 to rotate after being reduced in speed by the reducer 8, thereby driving the linkage on the disconnect switch to move, performing the closing and opening operations on the disconnect switch. When the operation panel 18 is de-energized, slide the protective baffle 20 open and insert the hand crank into the hand crank socket. Inside slot 9, rotating clockwise allows for closing the circuit breaker, while rotating counterclockwise allows for opening the circuit breaker. The transparent cover 14 on the outside of the closing button 13 protects against accidental touches. When closing the circuit breaker is required, the magnet 16 is removed from the control panel 18, the anti-detachment rotating rod 15 is rotated to a horizontal position, and then the transparent cover 14 is removed from the anti-detachment rotating rod 15 through the rod hole 17. The transparent cover 14 can then be flipped up and opened, allowing the closing button 13 to be pressed to close the circuit breaker.

[0018] The control box 2 on the upper side of the control panel 18 is equipped with a drive motor 7. The output end of the drive motor 7 is connected to a reducer 8. The reducer 8 has a hand crank slot 9 on the side away from the drive motor 7. The drive motor 7 provides power for the movement of the linkage structure on the disconnect switch. The reducer 8 can reduce the speed of the drive motor 7 and increase the torque, making it easier to drive the linkage mechanism.

[0019] The control box 2 is slidably connected to the hand crank slot 9. A stop button 12 is provided on one side of the closing button 13. The protective baffle 20 can block and protect the hand crank slot 9.

[0020] A trip button 11 is provided on the upper side of the closing button 13, and a grounding knob 10 is provided on one side of the trip button 11.

[0021] The output end of the reducer 8 is connected to the transmission disc 5, and a handle 6 is installed on the door 3 between the two mortise locks 4. The handle 6 makes it easy to open or close the door 3.

[0022] The lower side of the control box 2 is fixedly connected to the support conduit 1. The drive motor 7 is connected to the control box 2 by bolts, and the reducer 8 is connected to the housing of the drive motor 7 by bolts.

[0023] The working principle of the substation disconnector operating mechanism with anti-accidental contact function provided by this invention is as follows: Figures 1-4As shown, when it is necessary to operate and adjust the disconnect switch, insert the key into the mortise lock 4 to open the mortise lock 4, thereby opening the box door 3. Then, operate and adjust using the buttons on the operation panel 18. After pressing the closing button 13 and the opening button 11, the drive motor 7 drives the transmission disc 5 to rotate after being reduced in speed by the reducer 8, thereby driving the linkage on the disconnect switch to move, performing the closing and opening operations on the disconnect switch. When the operation panel 18 is de-energized, slide the protective baffle 20 open and insert the hand crank into the hand crank socket. Inside slot 9, rotating clockwise allows for closing the circuit breaker, while rotating counterclockwise allows for opening the circuit breaker. The transparent cover 14 on the outside of the closing button 13 protects against accidental touches. When closing the circuit breaker is required, the magnet 16 is removed from the control panel 18, the anti-detachment rotating rod 15 is rotated to a horizontal position, and then the transparent cover 14 is removed from the anti-detachment rotating rod 15 through the rod hole 17. The transparent cover 14 can then be flipped up and opened, allowing the closing button 13 to be pressed to close the circuit breaker.
