Description

Technical Field

[0001] This application relates to the field of power testing technology, and in particular to an integrated device for analog circuit breakers and interfaces for power distribution automation testing. Background Technology

[0002] In modern power systems, distribution automation technology is widely used at all levels of the power grid, especially in the distribution network sector.

[0003] Distribution automation enables the efficient and reliable operation of power distribution systems through remote control and monitoring. With the development of smart grid technology, the commissioning and maintenance of distribution terminal equipment have become more complex and important.

[0004] Traditional power distribution terminal testing equipment typically uses aviation plugs as interfaces, while most testing instruments are equipped with rubber terminals, which leads to interface mismatch issues, resulting in operational complexity and the possibility of misoperation.

[0005] In the daily operation of power distribution systems, commissioning personnel need to frequently conduct warehouse commissioning, on-site installation commissioning, and daily inspection commissioning. These tasks are usually carried out in narrow, poorly lit environments. Mismatched interfaces and incorrect connections may lead to serious electrical faults, such as short circuits or equipment damage.

[0006] Furthermore, the commissioning of distribution terminals also involves the application of analog circuit breakers. Existing analog circuit breakers on the market are mainly designed for relay protection devices and typically support 110V output voltage, while distribution terminals often require 24V or 48V output voltage during commissioning. Therefore, existing equipment has significant shortcomings in voltage matching and cannot meet the actual commissioning requirements.

[0007] Furthermore, the existing analog circuit breaker is designed independently of the aviation plug, and multiple devices need to be used together during testing. This not only increases the workload of debugging, but also makes it inconvenient to carry and operate on site.

[0008] Therefore, there is an urgent need to provide a new solution to address the shortcomings of existing power distribution automation testing equipment in terms of interface design, function implementation, and portability. Summary of the Invention

[0061] This application discloses an integrated device for simulating circuit breakers and interfaces for power distribution automation testing.

[0062] Please see Figures 1 to 5 One embodiment of the integrated analog circuit breaker and interface device for power distribution automation testing provided in this application includes:

[0063] The device body 100, the interface module, and the simulated circuit breaker module.

[0064] The interface module is installed on the device body 100 and includes a first aviation socket 1 with 26 pins and two second aviation sockets 2 with 10 pins each.

[0065] The terminal side of the first aviation socket 1 is connected via a wire harness to a first terminal plug 11 with 6 pins and a second terminal plug 12 with 14 pins; the terminal sides of both second aviation sockets 2 are connected to a third terminal plug 21 with 10 pins.

[0066] The 26-pin first aviation socket 1 and the 10-pin second aviation socket 2 in this application are existing aviation socket structures. They can be fixed on the device body 100 by aligning the mounting holes of the annular flange portion on its outer circumference with the mounting holes on the device body 100, and then fastening them with screws. The specific details are not elaborated here.

[0067] Similarly, the first terminal plug 11 and the second terminal plug 12 are existing terminal-side plugs used to connect power distribution terminals, and will not be described in detail.

[0068] The interface side of the first aviation socket 1 is connected to multiple first interface sockets fixed to the main body 100 of the device.

[0069] Each of the two second aviation sockets 2 has multiple second interface sockets fixed to the main body 100 of the device connected to its interface side. The number of second interface sockets can be up to 7, and some of them are banana sockets.

[0070] The main body 100 of the device is marked with corresponding labels for the first interface socket and the second interface socket.

[0071] The pin definitions of the first aviation socket 1 connected to the first interface socket and the corresponding identifiers of the first interface socket are shown in Table 1 below:

[0072]

[0073] From Table 1 above and Figure 1 , Figure 3 It can be seen that:

[0074] The pins numbered 7-12 can be connected to the first interface socket to form a socket group for current input.

[0075] The first interface sockets connected to pins 1-6 can form a socket group for control signals.

[0076] The first interface sockets connected to pins 19-22 can form a socket group for position signals.

[0077] It can be seen that the first aviation socket 1 is connected to at least 16 first interface sockets, namely, energy storage- / power- socket 41, energy storage+ / power+ socket 42, closing- socket 43, closing+ socket 44, opening- socket 45, opening+ socket 46, A-phase current socket 31, B-phase current socket 32, C-phase current socket 33, phase common terminal socket 34, zero-sequence current socket 35, zero-sequence common terminal socket 36, communication common terminal socket 51, closing socket 52, opening socket 53, and energy storage socket 54.

[0078] The pin definitions of the second aviation socket 2 connected to the second interface socket and the corresponding markings of the first interface socket are shown in Table 2 below:

[0079]

[0080] From Table 2 above and Figure 2 , Figure 3 It can be seen that:

[0081] The second sockets corresponding to pins 1-3 can form a power input socket group;

[0082] The second sockets corresponding to pins 5-8 can form a measurement socket group; one of the measurement socket groups corresponding to the second aviation socket 2 can be used for load-side PT measurement, while the other measurement socket group corresponding to the second aviation socket 2 can be used for power-side PT measurement.

[0083] The two second aviation sockets 2 are connected to at least four second interface sockets, which are banana sockets, specifically voltage acquisition 1 socket 61, voltage acquisition 2 socket 62, voltage acquisition 3 socket 63 and acquisition common terminal socket 64.

[0084] The RVVP in the table above refers to a cable with a soft conductor, PVC insulation, an outer shield, and a PVC sheath.

[0085] like Figure 4 as well as Figure 5 As shown, the simulated circuit breaker module of this application is installed in the main body 100 of the device and includes a control unit 72, an operation unit 73, a pulse power detection unit 71, a 48V voltage regulator unit 75 and a 24V voltage regulator unit 74.

[0086] The operation unit 73 is electrically connected to the control unit 72.

[0087] The control unit 72 includes a microprocessor (MCU) as its core, which receives external control signals, performs logical operations and processing, and issues control commands to simulate the opening and closing actions of the circuit breaker. It has a signal input port (receiving control signals from test equipment or control system, such as opening and closing commands, protection action signals, etc.) and a signal output port (feeding back the status signals of the simulated circuit breaker to the test equipment or control system, such as opening and closing position signals, fault signals, etc.).

[0088] The operating unit 73 is a circuit breaker simulation structure (e.g., including optocouplers and relays) and performs opening and closing operations according to the instructions of the control unit 72.

[0089] The main body 100 of the device is also provided with a connection operation unit 73, a manual closing operation component 731 (e.g., a button) for manual operation, and a manual opening operation component 732 (e.g., a button) for manual operation.

[0090] There are four pulse power detection units 71. The signal input terminals of the four pulse power detection units 71 are sequentially connected to 24V trip input signal socket 81, 24V closing input signal socket 83, 48V trip input signal socket 84, which are fixed to the main body 100 of the device. 24V trip input signal socket 81 and 48V trip input signal socket 82 share the negative terminal socket, and 24V closing input signal socket 83 and 48V closing input signal socket 84 also share the negative terminal socket, making the structure more compact.

[0091] The signal output terminals of the four pulse power detection units 71 are all connected to the control unit 72. The pulse power detection unit 71 designed in this application is composed of diodes, Hall sensors, and resistors and capacitors. The high-power resistor is responsible for detecting the voltage, and then the Hall sensor detects the current of the circuit. According to P=UI, when the external closing and opening pulse signal is input and meets the power requirements, the pulse power detection unit 71 acquires the signal through the ADC interface of the control unit 72 and then makes a judgment.

[0092] The control unit 72 is also connected to a trip output signal socket 85 and a closing output signal socket 86 fixed to the main body 100 of the device. The test equipment is connected to the trip output signal socket 85 and the closing output signal socket 86 to receive feedback analog circuit breaker status signals.

[0093] There are two 24V voltage regulator units 74. The signal output terminals of the two 24V voltage regulator units 74 are connected to the control unit 72, and the signal input terminals of the two 24V voltage regulator units 74 are connected to a 24V power input socket 741 fixed on the main body 100 of the device.

[0094] There are two 48V voltage regulator units 75. The signal output terminals of the two 48V voltage regulator units 75 are connected to the control unit 72, and the signal input terminals of the two 48V voltage regulator units 75 are connected to a 48V power input socket 751 fixed on the main body 100 of the device.

[0095] In this application, both the 24V voltage regulator unit 74 and the 48V voltage regulator unit 75 can be voltage regulator circuits composed of a DC-DC converter and a low dropout linear regulator to ensure the provision of stable 24V / 10A power or 48V / 5A power.

[0096] In this simulated circuit breaker design, when the pulse power detection unit 71 detects that the input signal is established and the control unit 72 has completed its internal processing, the control unit 72 controls the optocoupler to drive the relay to perform node control operations through the GPIO port.

[0097] The main body 100 of the device is equipped with markings that correspond one-to-one with the 24V trip input signal socket 81, the 24V closing input signal socket 83, the 48V trip input signal socket 82, the 24V power input socket 741, and the 48V power input socket 751.

[0098] like Figure 5 as well as Figure 6 As shown, the 24V trip input signal socket 81 and the 24V closing input signal socket 83 can be marked with +24V on the main body 100 of the device, while the 48V trip input signal socket 82 and the 48V closing input signal socket 84 can be marked with +48V. The 24V trip input signal socket 81 and the 48V trip input signal socket 82 can be marked with trip input together.

[0099] The 24V power input socket 741 can be set with a DC24V label, and the 48V power input socket 751 can be set with a DC48V label. Both the 24V power input socket 741 and the 48V power input socket 751 can be set with an auxiliary power label.

[0100] The integrated analog circuit breaker and interface device for power distribution automation testing designed in this application has the following advantages:

[0101] 1. A first aviation socket 1 with 26 pins and two second aviation sockets 2 with 10 pins are integrated together, with each socket's interface side connected to multiple first and second interface sockets, and each socket is individually labeled. This allows the power distribution terminal tester to easily connect to the power distribution terminal under test via the first and / or second interface sockets. The interface module of this application, acting as a connection relay module, achieves interface uniformity, enabling existing power distribution terminal testers to easily and securely connect to the power distribution terminal via this application's interface module.

[0102] 2. The simulated circuit breaker module is designed with a pulse power detection unit 71, a 48V voltage regulator unit 75, and a 24V voltage regulator unit 74 to support 24V / 10A or 48V / 5A power verification, meet the debugging requirements of different voltage levels, better adapt to the special testing requirements of power distribution terminals, and improve adaptability.

[0103] 3. Integrating the interface module with the simulated circuit breaker module reduces the types of debugging equipment and improves work efficiency.

[0104] The above is Embodiment 1 of an integrated device for simulated circuit breakers and interfaces for power distribution automation testing provided in this application. The following is Embodiment 2 of the same device. Please refer to the following for details. Figures 1 to 6 .

[0105] Based on the solution of Embodiment 1 above:

[0106] Furthermore, such as Figure 3 As shown, one of the two sets of second interface sockets connected to the two second aviation sockets 2 is a shared three-phase power socket 65 (connecting pins 1-3 of the second aviation socket 2); the neutral and live wires of the three-phase power socket 65 connected to the two second aviation sockets 2 are each equipped with a first control switch 66. A standard three-phase power socket 65 is used for the tester to supply power to the object under test through the second aviation socket 2. A standard power cord is used to connect the three-phase power socket 65, and a first control switch 66 is set on the neutral wire to prevent cross-connection with the signal wire of the banana plug. At the same time, the addition of a first control switch 66 on the live wire greatly improves safety.

[0107] Furthermore, it also includes a battery (not shown in the figure), which may be a lithium battery and is built into the main body 100 of the device.

[0108] The output of the power supply battery is electrically connected to the interface module and the analog circuit breaker module respectively via the second control switch; an inverter module is installed on the line connecting the power supply battery to the interface module to convert the DC power output from the power supply battery into AC power and then deliver it to the interface module.

[0109] The power supply battery provides at least 3 hours of continuous power (the exact time varies depending on the battery capacity), ensuring that the device can still operate normally in the absence of an external power source. When there is no external power, the power supply battery can provide the required AC power to the inverter module output interface module or the required DC power to the analog circuit breaker module.

[0110] Furthermore, the main body 100 of the device is provided with a first switch operation component (not shown in the figure) connected to the first control switch 66.

[0111] like Figure 5 As shown, the main body 100 of the device is provided with a second switch operation component 91 connected to the second control switch (the second switch operation component 91 can be a knob component, and the main body 100 of the device is provided with corresponding markings, such as battery and mains power. When the pointer of the second switch operation component 91 points to the corresponding marking, it is in the corresponding switch control state. When it points to the battery marking, it is in the battery use state; when it points to the mains power, it is in the external power use state, and the external power is used to charge the power supply battery at the same time).

[0112] Furthermore, such as Figure 5 As shown, the main body 100 of the device is also provided with a third switch operation component 92 for connecting the inverter module. The third switch operation component 92 is a button component. When the power supply battery is used, the inverter module is turned on by the third switch operation component 92, which is regarded as using the power supply battery to power the interface module.

[0113] Furthermore, such as Figure 4 As shown, to facilitate interactive operation, the simulated circuit breaker module also includes an interactive unit 76, which is electrically connected to the control unit 72.

[0114] Specifically, such as Figure 5 As shown, the interactive unit 76 includes a display 87 and an interactive operation component 88, which are fixed to the main body 100 of the device.

[0115] The display 87 is a 1.8-inch LCD display, while the interactive operation component 88 can be a digital encoder button EC11. The display 87 displays an interactive UI interface, which can be used to set the delay action time of the analog circuit breaker. EC11 serves as an interactive button; rotating EC11 scrolls through the menu and numbers, while pressing EC11 confirms and saves the operation.

[0116] Furthermore, infrared beam-beam modules (not shown in the figure) are installed on the first interface socket, the second interface socket, the 24V trip input signal socket 81, the 24V closing input signal socket 83, the 48V trip input signal socket 82, the 24V power input socket 741, and the 48V power input socket 751, respectively, to detect whether they are properly connected to their corresponding mating plugs.

[0117] Specifically, each interface socket can have a through-hole that runs through it along its radial direction. An infrared transmitter and an infrared receiver can be installed at both ends of the through-hole. When the plug is properly inserted, it will block the infrared receiver from receiving the infrared light emitted by the infrared transmitter, and the indicator light connected to it will light up, thereby indicating to the operator that the plug is not properly inserted and ensuring the reliability of the connection.

[0118] It can also add protection functions for the current and voltage terminals. Overcurrent protection is set on the current terminal of the first interface socket and the second interface socket, and overvoltage protection is set on the voltage terminal to prevent equipment damage caused by misoperation or electrical fluctuations during the commissioning process.

[0119] Furthermore, such as Figure 5 As shown, the main body 100 of the device includes a housing 101 and a cover 102; the housing 101 has an installation cavity for installing the interface module and the simulated circuit breaker module; a control panel 103 is installed on the top of the housing 101.

[0120] The first interface socket, the second interface socket, the 24V tripping input signal socket 81, the 24V closing input signal socket 83, the 48V tripping input signal socket 82, the 24V power input socket 741, and the 48V power input socket 751 are all fixed on the control panel 103; correspondingly, the second switch operating component 91, the third switch operating component 92, the display 87, the interactive operating component 88, the manual closing operating component 731, and the manual tripping operating component 732 are also fixed on the control panel 103.

[0121] The lid 102 is installed on the top of the box body 101. Specifically, one side of the lid 102 can be hinged to the box body 101 via a hinge, and the other side can be detachably connected to the box body 101 via a buckle.

[0122] Furthermore, such as Figure 6As shown, the first interface socket, the second interface socket, the 24V tripping input signal socket 81, the 24V closing input signal socket 83, the 48V tripping input signal socket 82, the 24V power input socket 741, and the 48V power input socket 751 are all prepared according to preset colors. Correspondingly, the second switch operation component 91, the third switch operation component 92, the display 87, the interactive operation component 88, the manual closing operation component 731, and the manual tripping operation component 732 are also prepared according to preset colors.

[0123] The above provides a detailed description of an integrated analog circuit breaker and interface device for power distribution automation testing. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
