Description

Technical Field

[0001] The present application relates to the technical field of power grid equipment, and in particular to an adaptive detection device for a controlled terminal. Background Art

[0002] In order to better understand this application, the terms that appear in this application will be explained. Controlled terminal: access terminal equipment in the power system.

[0003] Distribution automation: refers to the use of computers, information and communication technologies as the basis for the primary grid and equipment of the distribution network, and the integration of information with related application systems to achieve monitoring, control and rapid fault isolation of the distribution network, and provide real-time data support for the distribution management system. Through rapid fault handling, the reliability of power supply is improved, and by optimizing the operation mode, the power supply quality is improved, and the efficiency and benefits of power grid operation are enhanced.

Based on these implementation methods, those skilled in the art may replace, splice or combine certain features or examples, which should still be regarded as the disclosed contents of the present application.

[0048] The present application provides a controlled terminal adaptive detection device, a circuit module for adaptive detection, including: a device module connected to the circuit module; the device module is provided with an aviation plug socket and an aviation plug; the aviation plug is provided with a plug part, an elastic telescopic mechanism, a push button and an aviation plug shell; the plug part is sleeved and installed at the lower end of the elastic telescopic mechanism, and the push button controls the elastic telescopic mechanism to drive the plug part to telescope; the elastic telescopic mechanism includes a sleeved sliding claw sleeve, a push rod and a guide rail, the sliding claw sleeve and the push rod are slidably sleeved in the aviation plug shell where the guide rail is located, the sliding claw sleeve is rotatably installed at the lower end of the push rod, and the push rod drives the sliding claw sleeve to slide along the aviation plug shell where the guide rail is located; the guide rail is fixed in the aviation plug shell; the push button is fixed on the top of the push rod, and the bottom of the push rod abuts against the plug part; when the push button is in a pressed state, the aviation plug is inserted into the aviation plug socket, and the aviation plug shell is connected to the device panel to form a cavity for accommodating the elastic telescopic mechanism. The elastic expansion mechanism in the aviation plug drives the plug part to extend and be electrically connected to the aviation socket, thereby preventing dust, sand and the like from entering the aviation socket and further ensuring good contact between the aviation plug and the aviation socket.

[0049] The circuit module is electrically connected to the device module. Specifically, the circuit module is based on an electromagnetic relay contact automatic control circuit, which is commonly used in the prior art and can realize the control of electromagnetic relays. Electromagnetic relays are used to simulate the circuit breaker of the power grid to test whether the instructions of the distribution network measurement and control terminal FTU are executed accurately. During the test, the FTU can be disconnected from the grid to test the function of the FTU.

[0050] like Figure 1 The device module in the embodiment of the present application is shown, and the device module includes an aviation socket 10 , an aviation plug 20 , an indicator light, a voice prompter (not shown), a conversion switch 40 and a device panel 50 .

[0051] Specifically, the aviation socket 10, the aviation plug 20, the indicator light and the conversion switch 40 are all arranged on the device panel 50. The positions of the aviation socket 10, the aviation plug 20, the indicator light and the conversion switch 40 on the device panel 50 can be set according to specific working conditions.

[0052] Among them, the aviation plug 20 is provided with a plug part 201, an elastic telescopic mechanism 202, a push button 203 and an aviation plug shell; the plug part 201 is sleeved and installed on the lower end of the elastic telescopic mechanism 202, and the push button 203 controls the elastic telescopic mechanism 202 to drive the plug part 201 to telescope.

[0053] like Figure 3 As shown, the plug part 201, the elastic telescopic mechanism 202 and the push button 203 are arranged inside the aviation plug housing. Specifically, the plug part 201 is arranged at the lower end of the elastic telescopic mechanism 202, and the push button 203 is arranged at the upper end of the elastic telescopic mechanism 202. In other words, the push button 203 is connected to the plug part 201 through the elastic telescopic mechanism 202.

[0054] When a certain force is applied to the push button 203 so that the push button 203 is in different states, the push button 203 can control the elastic telescopic mechanism 202 to drive the plug part 201 to telescope.

[0055] Among them, the elastic telescopic mechanism 202 includes a set of sliding claw sleeve 2021, a push rod 2022 and a guide rail 2023. The sliding claw sleeve 2021 and the push rod 2022 are slidably mounted in the aviation plug shell where the guide rail 2023 is located. The sliding claw sleeve 2021 is rotatably installed at the lower end of the push rod 2022. The push rod 2022 drives the sliding claw sleeve 2021 to slide along the aviation plug shell where the guide rail 2023 is located; the guide rail 2023 is fixed in the aviation plug shell.

[0056] like Figure 4 The figure is a schematic diagram of the structure of the elastic telescopic mechanism 202, which includes the sliding claw sleeve 2021, the push rod 2022 and the guide rail 2023. The housing where the guide rail 2023 is located provides a storage space and a movement track for the sliding claw sleeve 2021 and the push rod 2022. It can be understood that the sliding claw sleeve 2021 and the push rod 2022 are slidably mounted in the aviation plug housing where the guide rail 2023 is located, and slide along the aviation plug housing where the guide rail 2023 is located. The push rod 2022 is moved by Figure 4 The slide groove on the right side of the stopper 2022-1 slides in the strip-shaped guide rail 2023. Figure 6 As shown in the dotted line position, the guide rails 2023 are an even number, which is the same as the number of the slide grooves of the push rod 2022, and are distributed in the cylinder of the aviation plug housing.

[0057] Specifically, the sliding claw sleeve 2021 is rotatably installed on the lower end of the push rod 2022 through a rotating column 2021-1. When the push rod 2022 slides in the guide rail 2023, the sliding claw sleeve 2021 will also be driven to rotate and slide. Among them, the guide rail 2023 is fixed in the aviation plug housing. The guide rail 2023 is fixed in the aviation plug housing as a strip-mounted protrusion. The guide rail 2023 can also be fixed to the inner wall of the cylindrical aviation plug housing by precision casting. Other fixing methods are not excluded to fix the guide rail 2023 in the aviation plug housing. The push rod 2022 has a slide groove that cooperates with the guide rail 2023. The stroke of the push rod 2022 exceeds the length of the guide rail 2023. Figure 5As shown, the sliding claw sleeve 2021 has two slots of different depths, namely the first slot 2021-A and the second slot 2021-B. Specifically, the first slot 2021-A and the second slot 2021-B cooperate with the guide rail 2023. In the embodiment of the present application, the first slot 2021-A is a slot with a shorter stroke, and the second slot 2021-B is a slot with a longer stroke. The stroke of the first slot 2021-A and the stroke of the second slot 2021-B can also be set according to specific actual conditions. The first slot 2021-A and the second slot 2021-B cooperate with the guide rail 2023 to enable the sliding claw sleeve 2021 to achieve different strokes. One of the shorter first slots 2021-A also cooperates with the stopper 2022-1.

[0058] The push button 203 is fixed on the top of the push rod 2022, the bottom of the push rod 2022 abuts against the sliding claw sleeve 2021, and the sliding claw sleeve 2021 is fixedly connected to the plug part 201; when the push button 203 is in a pressed state, the aviation plug 20 is inserted into the aviation plug socket 10, and the first card slot 2021-A in the sliding claw sleeve 2021 is clamped with the guide rail 2023, such as Figure 2 As shown, the elastic expansion mechanism 202 in the aviation plug 20 drives the plug portion 201 to extend and be electrically connected to the aviation plug socket 10 .

[0059] Specifically, Figure 2 As shown, the push button 203 is fixed on the top of the push rod 2022 of the elastic telescopic element 202, so that the staff can operate the push button 203 conveniently. By pressing the push button 203, the push rod 2022 can be controlled to slide. At the same time, the bottom of the push rod 2022 abuts against the sliding claw sleeve 2021, which drives the plug part 201 to extend and retract accordingly. When the push button 203 is pressed, the push button 203 pushes the push rod 2022 to slide downward, and further drives the plug part 201 to extend, so that the plug part 201 contacts the aviation plug socket 10, so that the aviation plug 20 is electrically connected to the aviation plug socket 10.

[0060] The plug portion 201 and the inner wall material of the aviation socket 10 may be the same or different, but both are conductive materials, and the specific material may be determined according to specific working conditions.

[0061] It can be understood that, especially in areas where sand is more serious, the plug part 201 of the aviation plug 20 is electrically connected to the aviation plug socket 10 through the push button 203, so that dust, sand and other fine particles can be prevented from entering the aviation plug socket 10, and the aviation plug 20 can be better in contact with the aviation plug socket 10 to ensure that the entire detection device can operate well.

[0062] The structures of the sliding claw sleeve 2021 and the push rod 2022 will be described in detail below.

[0063] The sliding claw sleeve 2021 is provided with a rotating column 2021-1 and a rotating bracket 2021-2. The rotating column 2021-1 is a cylindrical structure, and the rotating bracket 2021-2 having a slot for accommodating different strokes of the guide rail surrounds the rotating column 2021-1.

[0064] like Figure 5 As shown, the sliding claw sleeve 2021 is composed of the centrally arranged rotating column 2021-1 and the rotating bracket 2021-2 surrounding the rotating column 2021-1. Specifically, the rotating column 2021-1 is a cylindrical structure, and the rotating column 2021-1 is installed in the central hollow part of the push rod 2022, that is, the rotating column 2021-1 can drive the sliding claw sleeve 2021 to rotate. The rotating bracket 2021-2 having a slot for accommodating different strokes of the guide rail surrounds the rotating column 2021-1. The rotating bracket 2021-2 can match with the stopper 2022-1 set on the push rod 2022 during the rotation of the rotating column 2021-1, and can prevent the rotating column 2021-1 from rotating. The rotating column 2021-1 and the rotating bracket 2021-2 can be integrally formed.

[0065] Among them, a stopper 2022-1 matching the rotating bracket 2021-2 is provided at the lower end of the push rod 2022, and the stopper 2022-1 blocks the rotating bracket 2021-2 at different stroke positions from rotating and rising and falling.

[0066] like Figure 6 As shown, a round table is provided at the upper end of the push rod 2022, and the round table can be clamped with the first elastic element 2024 installed there. At the same time, the stopper 2022-1 is provided at the lower end of the push rod 2022, and the stopper 2022-1 is matched with the rotating bracket 2021-2, and can prevent the rotating bracket 2021-2 of different specific strokes from rotating and lifting.

[0067] Specifically, the center of the push rod 2022 is hollow, and the hollow portion at the lower end can accommodate the rotating column 2021 - 1 in the sliding claw sleeve 2021 .

[0068] The elastic telescopic mechanism 202 further includes a first elastic element 2024, which is sleeved between the top of the outer wall of the push rod 2022 and the aviation plug housing. A second elastic element 2011 is arranged outside the plug part 201, and the second elastic element 2011 is mounted on the bottom card platform 2012 of the plug part 201. The second elastic element 2011 provides elastic support for the components in the housing. Of course, the card platform 2012 can also be arranged flush with the device panel 50 and become one. The second elastic element 2011 is a spring, which is sleeved on the plug part 201, between the device panel 50 and the sliding claw sleeve 2021.

[0069] Specifically, the first elastic element 2024 is sleeved on the truncated cone position set at the upper end of the push rod 2022, and the second elastic element 2011 is sleeved on the card platform 2012 at the bottom end of the plug part 201, and the second elastic element 2011 is clamped between the card platform 2012 at the bottom end of the plug part 201 and the device panel 50. When the push button 203 is in a pressed state, the push button 203 is subjected to a certain force, so that the first elastic element 2024 at the top end of the outer wall of the push rod 2022 is in a compressed state, which will drive the push rod 2022 to slide toward the direction of the aviation plug socket 10, and the push rod 2022 drives the sliding claw sleeve 2021 to rotate and slide. At this time, the second elastic element 2011 located at the plug part 201 is also in a compressed state, and the push rod 2022 will push the plug part 201 at the lower end to extend toward the aviation plug socket 10, so that the plug part 201 is electrically connected to the aviation plug socket 10.

[0070] The push button 203 is in a reset state, and the elastic expansion mechanism 202 in the aviation plug 20 drives the plug part 201 to shrink and be disconnected from the aviation plug socket 10 .

[0071] In addition, it is necessary to disconnect the electrical connection between the aviation plug 20 and the aviation plug socket 10, and it is necessary to apply a certain force to the push button 203 so that the push button 203 is in a reset state. At this time, the first elastic element 2024 and the second elastic element 2011 restore the elastic force. Figure 4 shown.

[0072] Next, other components of the device module will be described in detail.

[0073] The device module surface is provided with a device panel 50, and the device panel 50 is a resin insulating board, which is used to accommodate the aviation plug socket 10, and the surface of the device panel 50 is used to fix the aviation plug 20. That is to say, the aviation plug socket 10 is arranged in the internal space of the device panel 50, and the aviation plug 20 is fixed on the surface of the device panel 50. The device panel 50 adopts the resin insulating board, which has the advantages of high impact strength, hard material, small thermal deformation, high temperature resistance, high impact resistance, etc. The device panel 50 can be customized according to the size of the detection device, so that the overall sealing performance of the entire detection device is better.

[0074] It can be understood that the electrical connection and disconnection between the aviation socket 10 and the aviation plug 20 is essentially the electrical connection and disconnection between the aviation socket 10 and the plug part 201 of the aviation plug 20. As can be seen from the above, the electrical connection and disconnection between the aviation plug 20 and the aviation socket 10 can be achieved by controlling the extension and retraction of the elastic retractable mechanism 202 by pressing the button 203.

[0075] The device module is further provided with indicator lights, which include a closed position indicator light 301 and an open position indicator light 302. The closed position indicator light 301 and the open position indicator light 302 are controlled to flash according to the signal of the feeder terminal.

[0076] Specifically, the indicator lights are arranged at the lower center of the device panel 50, and the indicator lights are a closed position indicator light 301 and an open position indicator light 302, and the closed position indicator light 301 and the open position indicator light 302 have different colors, and different colors can be set for the closed position indicator light 301 and the open position indicator light 302 according to actual work requirements. In the embodiment of the present application, the closed position indicator light 301 is a red indicator light, and the open position indicator light 302 is a green indicator light.

[0077] Wherein, the device module is also provided with a voice prompter, and when the feeder terminal detects a fault, the voice prompter issues a voice fault alarm.

[0078] Specifically, when the feeder terminal device fails, the voice prompter will issue a voice fault alarm to remind the emergency repair staff to perform emergency repairs.

[0079] The device module is further provided with the conversion switch 40, which is a rotary conversion switch with at least two gears. The rotary conversion switch selects a corresponding gear according to the output voltage of the feeder terminal aviation plug.

[0080] Specifically, the rotary conversion switch is arranged below the aviation plug socket, and the rotary conversion switch is provided with different gears, and different gears can be selected according to the output voltage of the feeder terminal aviation plug. In the embodiment of the present application, the rotary conversion switch is provided with three gears, namely, gear I, gear II, and gear III. In the specific working process, different gears can be selected according to the different voltages output by the feeder terminal aviation plug. At the same time, the rotary conversion switch has the advantages of smooth switching and high reliability.

[0081] The controlled terminal adaptive detection device is also provided with an independent power switch 60. The independent power switch 60 is arranged at a position slightly to the left below the indicator light. The type of the independent power switch 60 is connected to an external 220V power supply, the power supply size is 220V AC, and the required accessories are a 220V~24V AC / DC conversion module, which is maintenance-free. The output voltage fluctuation of the independent power switch 60 is ≦±10%, and the independent power switch 60 has the advantages of good continuous power supply and reliable use.

[0082] The device panel is also provided with instructions for use 70 , which are arranged at the upper left position of the device panel 50 . The instructions for use 70 describe in detail the process of using the detection device.

[0083] like Figure 7 As shown, the controlled terminal adaptive device of the present application also includes: an adaptive module in the prior art, which is a single-chip microcomputer system, used to realize adaptive detection, that is, to realize whether each navigation plug button can turn on the FTU and trigger each relay action, thereby simulating whether the FTU can control the circuit breaker on site. At present, the development technology of single-chip microcomputer system is relatively mature, and no more explanation is given here. Figure 7 As shown, the controlled terminal adaptive detection device is composed of the circuit module, the device module, the adaptive module, and the power switch. The circuit module is based on the electromagnetic relay automatic control circuit. The electromagnetic relay can be used to replace the circuit breaker and connect to the distribution network measurement and control terminal FTU through its electrical characteristics, so as to quickly detect faults without power outages.
