Description

Technical Field

[0001] This invention relates to the field of substation pressure plates, and more specifically, to a spring-loaded double-linked remote-controlled pressure plate. Background Technology

[0002] With the continuous advancement of smart grid construction and the continuous improvement of substation automation, the power system is rapidly developing towards full digitalization, networking, and intelligence. In this process, the secondary equipment of substations, as a key link in protection, monitoring, and control, directly affects the safety, stability, and operation and maintenance efficiency of the power grid. However, under the current technological conditions, the traditional pressure plate devices used extensively in the secondary circuits, especially the single-panel pressure plate that only supports local manual operation, have become one of the main bottlenecks restricting the realization of comprehensive remote monitoring and automated operation of substations.

[0003] Traditional single-pole switchboards typically employ a simple mechanical structure containing only main circuit contacts. Their function is limited to manually switching on and off the physical circuit. These switches lack remote status monitoring and feedback capabilities, requiring on-site confirmation by maintenance personnel before and after operation. This not only results in slow response and low operational efficiency but also increases the risk of personal injury and potential for misoperation. Structurally, single-pole switchboards generally lack effective status sensing and signal output mechanisms, making it impossible to interact with substation automation systems and failing to meet the practical needs of modern relay protection and control systems for real-time status visibility, controllability, and traceability.

[0004] With the increasing prevalence of digital protection and control systems, double pressure plates with color markings (e.g., red for trip pressure plates and yellow for function pressure plates) are often used in the field to distinguish different uses such as trip output and function activation / deactivation. Although the double structure improves the standardization and recognizability of operation to some extent, it is still essentially a passive component that requires manual on-site operation and does not have remote communication and remote control functions. Currently, some systems are trying to use these hardware pressure plates in conjunction with "soft pressure plates" in software logic, but the lack of hardware pressure plate status still prevents the system from achieving true closed-loop control and status verification, resulting in safety hazards caused by inconsistencies between the hardware and software pressure plate status settings.

[0005] Therefore, existing pressure plate technology has the following main drawbacks: 1. Lack of remote monitoring capability: The status of the pressure plate cannot be uploaded to the monitoring system in real time, which is not conducive to centralized monitoring and fault diagnosis.

[0006] 2. Reliance on manual on-site operation: Maintenance personnel must go to the site to perform commissioning and decommissioning operations, resulting in delayed response and making it unsuitable for unattended and remote operation and maintenance modes.

[0007] 3. Lack of status feedback mechanism: Traditional pressure plates cannot provide electrical or digital status signals, making it difficult to achieve linkage verification and anti-misoperation interlocking with automation systems.

[0008] 4. Insufficient integration with digital systems: In scenarios where hard and soft pressure plates are used together, the actual status of the hardware pressure plate cannot be automatically fed back, which increases the complexity of the system and the risk of misoperation.

[0009] To address the aforementioned issues, there is an urgent need to design a dual-plate device that can support real-time remote status feedback and accept remote control commands for status switching. This device should integrate status detection sensors and communication interfaces while retaining the reliable physical connection characteristics of existing platens, enabling local perception, remote transmission, and remote control of platen status. This would truly open up the automation loop of the "last mile" of secondary equipment operation and promote the evolution of substation operation and maintenance mode towards comprehensive intelligent operation and maintenance.

[0010] Therefore, it is necessary to propose a spring-loaded double-linked remote control pressure plate to solve the above problems. Summary of the Invention

[0011] To overcome at least one of the defects (deficiencies) of the prior art described above, the present invention provides a spring-loaded double-linked remote control pressure plate.

[0012] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a wire spring type double remote control pressure plate, including a remote control actuator and a double pressure plate body; The remote control actuator is connected to the double pressure plate body, and the remote control actuator is provided with an ejection mechanism and a rotation mechanism respectively. The ejection mechanism is connected to the rotary blade switch that passes through the double pressure plate body via a pusher. The outside of the pusher is connected to the rotation mechanism, so that the rotary blade switch can extend, retract and rotate on the double pressure plate body. The double pressure plate body is provided with a double electrical connection circuit. The double electrical connection circuit is provided with at least two non-interfering first pair of wire spring plugs and second pair of wire spring plugs. The first pair of wire spring plugs is used to control the engagement and disengagement status of the double pressure plate body, and the second pair of wire spring plugs is used to provide real-time feedback on the engagement and disengagement status of the double pressure plate body to the background. The rotary blade switch is provided with at least two non-interfering first and second electrodes. When the rotary blade switch is in the compressed state, the first and second electrodes on the rotary blade switch are respectively connected to the first pair of spring plugs and the second pair of spring plugs on the double pressure plate body. When the rotary blade switch extends outward under the drive of the ejection mechanism, the first and second electrodes on the rotary blade switch separate from the first pair of spring plugs and the second pair of spring plugs on the double pressure plate body. Since the rotary blade switch is provided with at least two non-interfering first and second electrodes, and the double pressure plate body is provided with a double electrical connection circuit, and the double electrical connection circuit is provided with at least two non-interfering first and second pairs of spring plugs, the first pair of spring plugs is used to connect to the double pressure plate body. The first pair of spring-loaded plugs controls the activation and deactivation status of the double-panel body, while the second pair of spring-loaded plugs provides real-time feedback to the backend regarding the activation and deactivation status of the double-panel body. Therefore, this design enables remote monitoring and real-time status feedback. The spring-loaded double-panel remote-controlled pressure plate disclosed in this invention saves manpower and achieves rapid response. It retains the operational advantages of a single-panel remote-controlled pressure plate without requiring additional detection devices to meet the detection requirements, thus saving on installation costs and R&D costs. It also avoids power plant operation and maintenance risks arising from subsequent installation. Furthermore, the double-panel remote-controlled pressure plate allows for remote operation of the circuit breaker, enabling dispatchers to remotely view the pressure plate status on the terminal, reducing manual verification errors and improving power grid operation efficiency.

[0013] Furthermore, it also includes a first infrared beam beam panel, a second infrared beam beam panel, a first infrared beam beam tube, a second infrared beam beam tube, and at least two beam beam through holes; The first infrared beam lamp is mounted on the first infrared beam lamp plate, and the second infrared beam lamp is mounted on the second infrared beam lamp plate. The first infrared beam lamp plate and the second infrared beam lamp plate are respectively horizontally mounted on the remote control actuators on both sides of the pusher. The through-hole penetrates the actuator. When the actuator moves or rotates to its position, the light emitted by the first or second infrared through-hole passes through the actuator and is received by the second or first infrared through-hole. With the arrangement of the first infrared through-hole board, the second infrared through-hole board, the first infrared through-hole, the second infrared through-hole, and at least two through-holes, the position of the actuator can be determined by infrared through-hole, thereby determining the current state of the rotary switch.

[0014] Furthermore, it also includes a circuit board, which is connected to the first infrared beam beam board, the second infrared beam beam board, the first infrared beam beam tube, and the second infrared beam beam tube respectively. Since the circuit board is connected to the first infrared beam beam board, the second infrared beam beam board, the first infrared beam beam tube, and the second infrared beam beam tube respectively, the beam beam situation can be quickly transmitted to the circuit board for judgment of the status of the wire spring type double remote control pressure plate.

[0015] Furthermore, the ejection mechanism includes an ejection drive spring, a push rod, a limit block, and an ejection action reduction motor disposed within the remote control actuator; The pusher has a recessed through hole, and the push-out drive spring is disposed on the recessed through hole; One end of the push rod is connected to the push-out action reduction motor, and the other end is inserted into the push-out drive spring in the concave through hole; The limiting block is set on the push rod to limit the push-out drive spring. The rotary blade switch passes through the double pressure plate body and is connected to the pusher. The push rod is driven by the push-out action reduction motor to push out the pusher, thereby pushing out the rotary blade switch. When the push rod moves backward under the drive of the push-out action reduction motor, the pusher is reset under the action of the push-out drive spring, and the rotary blade switch returns to the initial position.

[0016] Furthermore, the rotating mechanism includes a rotary reduction motor and a rotary gear shaft, and the pusher is provided with a pusher gear section; The rotary motion reduction motor is installed inside the remote control actuator. The end of the rotary gear shaft is connected to the rotary motion reduction motor. The gear part of the rotary gear shaft meshes with the gear part of the propeller. The rotary motion reduction motor drives the rotary gear shaft to rotate, so that after the rotary gear shaft and the gear feature on the propeller mesh with each other, the propeller is driven to rotate.

[0017] Furthermore, the propeller gear portion is 1 / 4 of the circumference of the propeller. In practical applications, the propeller gear portion can be configured as needed, and these are all alternative solutions that are easily conceived by those skilled in the art.

[0018] Furthermore, the double pressure plate body includes a clutch, a pin, a double pressure plate body base, a pan head screw, a plastic nut, a return spring, and a limiting groove; The dual electrical connection circuit is set on the base of the dual pressure plate body, the plastic nuts are respectively set on the outside of the first pair of wire spring plugs and the second pair of wire spring plugs, and the pan head screws are respectively fixed on the first pair of wire spring plugs and the second pair of wire spring plugs. The rotary blade switch passes through the double pressure plate body base. The clutch is fixed to the rotary blade switch by a pin. The limiting groove is provided on the rotary blade switch. The return spring is sleeved on the rotary blade switch between the clutch and the limiting groove. Since the dual electrical connection circuit is provided on the double pressure plate body base, and the rotary blade switch passes through the double pressure plate body base and is connected to the pusher, the rotary blade switch can be lifted when the pusher is pushed out, so that the first electrode and the second electrode on the rotary blade switch are separated from the first pair of wire spring plugs and the second pair of wire spring plugs on the double pressure plate body, respectively, thereby realizing the control of opening and closing the switch. The return spring and the limiting groove can automatically reset the rotary blade switch when the pusher is retracted, which is simple and practical.

[0019] Furthermore, it also includes limit switches connected to the main circuit board; The clutch is provided with a pressing block, and the pusher is provided with a limiting groove for accommodating the pressing block. When the pusher is in the closed state, one end of the pressing block passes through the limiting groove of the pusher, and the other end is pressed against the limit switch. By setting the limit switch, the state of the pusher can be reported to the circuit board for the open and closed states, which is simple and convenient.

[0020] Furthermore, a label cover is provided on the top end face of the rotary disconnector, and there is a gap between the inside of the label cover and the top end face of the rotary disconnector. The gap is used to install a label, which is used to identify the line name of the substation control line.

[0021] Furthermore, the remote control actuator is provided with a through hole for the rotary knife switch to pass through, and the through hole is provided with a snap-fit ​​fixing position. The double pressure plate body is provided with a fastening fixing position. The double pressure plate body is fastened to the snap-fit ​​fixing position of the through hole through the fastening fixing position. With the setting of the snap-fit ​​fixing position and the fastening fixing position, the double pressure plate body can be quickly set on the remote control actuator, which is simple and convenient.

[0022] Compared with the prior art, the beneficial effects of the technical solution of the present invention are: The spring-loaded double-link remote control switch disclosed in this invention features at least two non-interfering first and second electrodes on the rotating shaft disconnector, and dual electrical connection circuits on the switch body. These circuits contain at least two non-interfering pairs of spring-loaded plugs. The first pair of spring-loaded plugs controls the switching on / off state of the switch body, while the second pair provides real-time feedback on this status to the backend. This design enables remote monitoring and real-time status feedback. The spring-loaded double-link remote control switch disclosed in this invention saves manpower and provides rapid response. It retains the operational advantages of a single-link remote control switch without requiring additional detection devices to meet remote control requirements. This saves on installation and R&D costs, avoids power plant maintenance risks associated with subsequent installation, and allows for remote operation and closing of the switch. Furthermore, the double-link remote control switch enables remote operation, allowing dispatchers to remotely view the switch status on a terminal, reducing manual verification errors and improving power grid efficiency.

Example

[0049] like Figure 12 As shown, at this time, the spring-loaded double remote control pressure plate is in the initial closed state, the limit switch reports the closed signal, the first infrared beam lamp and the second infrared beam lamp are in the initial beam position of the closed position, the rotary knife switch is in the normal compressed state, and the first electrode and the second electrode on the rotary knife switch are respectively connected to the first pair of spring plugs and the second pair of spring plugs in the base of the double pressure plate body.

[0050] like Figure 13 As shown, when the tripping operation command is issued, the push-out action reduction motor drives the thruster forward, pushing the rotary knife switch forward until it is fully pushed out, disconnecting the dual electrical connection circuit. At this time, the first and second infrared beam lamps are... Figure 4 They fired at each other from their positions and simultaneously triggered the next action.

[0051] like Figure 14 As shown, after the infrared trigger command for the next operation is issued, the rotary motion reduction motor drives the rotary gear shaft to rotate the pusher, which in turn drives the rotating shaft knife switch to rotate counterclockwise by 45 degrees. At this time, the first infrared beam lamp and the second infrared beam lamp are... Figure 5 They fired at each other from their positions and simultaneously triggered the next action.

[0052] like Figure 15As shown, when the infrared trigger sends the next operation command, the push-out action reduction motor drives the pusher to retract. The retraction of the pusher forces the rotary blade switch to retract. When the first infrared beam lamp and the second infrared beam lamp reach the next beam hole position, the push-out action reduction motor stops, and the rotary blade switch stops at a 45-degree angle on the double pressure plate body base. At this point, the opening action of the spring-loaded double remote control pressure plate ends, and it can wait for the closing operation command.

[0053] Before closing the circuit, the limit switch reports the open status. The first infrared beam lamp and the second infrared beam lamp are in the initial open position. The rotary knife switch is in the normal compressed state and the dual electrical connection circuit is in the disconnected state, waiting for the closing command.

[0054] like Figure 16 As shown, after the closing command is given, the push-out action reduction motor receives the command and drives the pusher forward, causing the rotary knife switch to push forward and reach a 45-degree open position. At this time, the first and second infrared beam lamps reach... Figure 7 At the indicated position, the next action is triggered simultaneously.

[0055] like Figure 17 As shown, when the infrared trigger command for the next operation is issued, the rotary motion reduction motor drives the rotary gear shaft to rotate the pusher. Simultaneously, the pusher drives the rotating shaft knife switch to rotate 45 degrees clockwise until it is parallel to the base of the double-plate body. At this time, the first and second infrared beam lamps are... Figure 8 They exchange fire at each other's positions and simultaneously begin triggering the next action.

[0056] like Figure 18 As shown, when the infrared trigger sends the next operation command, the push-out action reduction motor drives the pusher to retract. The retraction of the pusher forces the rotary blade switch to retract. When the first infrared beam lamp and the second infrared beam lamp reach the next beam hole position, the push-out action reduction motor stops. At this time, the first infrared beam lamp and the second infrared beam lamp are in the initial closed position hole position. The limit switch reports the closed signal, and the rotary blade switch closes parallel to the double pressure plate body base. The first electrode and the second electrode on the rotary blade switch are respectively connected to the first pair of wire spring plugs and the second pair of wire spring plugs in the double pressure plate body base, and the closed circuit is successful.
