Description

Technical Field

[0001] The present application relates to the technical field of power testing, and in particular to an integrated device of a simulated circuit breaker and an interface for power distribution automation testing. Background Art

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

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

[0004] Traditional power distribution terminal test equipment usually uses aviation plugs as interfaces, while most test instruments are equipped with rubber terminals, which have interface mismatch problems, resulting in operational complexity and the possibility of misoperation.

[0005] In the daily operation of the power distribution system, commissioning personnel need to frequently perform warehouse commissioning, on-site commissioning after installation, and daily patrol commissioning. These tasks are usually performed in a narrow, poorly lit environment. Interface mismatch and incorrect connection may cause serious electrical faults such as short circuits or equipment damage.

[0006] In addition, the debugging of the power distribution terminal also involves the application of simulated circuit breakers. The existing simulated circuit breakers on the market are mainly designed for relay protection devices and usually support an output voltage of 110V, while the power distribution terminal often requires an output voltage of 24V or 48V during debugging. Therefore, the existing equipment has obvious deficiencies in voltage matching and is difficult to meet the needs of actual debugging.

[0007] Furthermore, the existing simulated circuit breaker is designed to be independent of the aviation plug. When used for testing, multiple devices need to be used together, which not only increases the workload of debugging, but also is not convenient for carrying and on-site operation.

[0008] Therefore, it is urgent to provide a new solution to address the deficiencies of existing distribution automation test equipment in terms of interface design, function realization and portability. Summary of the invention

[0062] See also Figures 1 to 5 , an embodiment of a simulated circuit breaker and interface integrated device for distribution automation testing provided in an embodiment of the present application includes:

[0063] Device body 100, interface module and simulated circuit breaker module.

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

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

[0066] The first aviation socket 1 with 26 pins and the second aviation socket 2 with 10 pins in the present application are existing aviation plug structures, and the method of fixing them on the device body 100 can be to align the mounting holes of the annular flange part on the outer peripheral surface with the mounting holes on the device body 100, and then fasten them with tightening screws, which will not be described in detail.

[0067] Similarly, the first terminal plug 11 and the second terminal plug 12 are existing terminal-side plugs for connecting to a power distribution terminal, and their details are not described in detail.

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

[0069] The interface sides of the two second aviation sockets 2 are connected to a plurality of second interface sockets fixed to the device body 100 . The number of the second interface sockets may be 7, and some of them are banana sockets.

[0070] The device body 100 is provided with labels corresponding to the first interface socket and the second interface socket one by one.

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

[0072]

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

[0074] The first interface sockets corresponding to the pins with pin numbers 7-12 can form a socket group for current input.

[0075] The first interface sockets connected to the pins with pin numbers 1-6 can form a socket group for controlling the signal.

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

[0077] It can be known that the first aviation socket 1 is connected to at least 16 first interface sockets, namely energy storage- / power supply-socket 41, energy storage+ / power supply+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 end socket 34, zero sequence current socket 35, zero sequence common end socket 36, communication common end 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 identifications of the first interface socket are shown in Table 2 below:

[0079]

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

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

[0082] The second sockets corresponding to the pins with pin numbers 5-8 can form a measurement socket group; the measurement socket group corresponding to one second aviation socket 2 can be used for load-side PT measurement, and the measurement socket group corresponding to another 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, a voltage collection 1 socket 61 , a voltage collection 2 socket 62 , a voltage collection 3 socket 63 and a collection common end socket 64 .

[0084] The RVVP in the above table refers to a cable with a soft conductor PVC insulated wire plus a shielding layer and a PVC sheath.

[0085] like Figure 4 as well as Figure 5 As shown, the simulated circuit breaker module of the present application is installed in the device body 100, including a control unit 72, an operation unit 73, a pulse power detection unit 71, a 48V voltage stabilizing unit 75 and a 24V voltage stabilizing 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 the core, which receives external control signals for logic operations and processing, and issues control instructions to simulate the opening and closing actions of the circuit breaker. It has a signal input port (receives control signals from the test equipment or control system, such as opening and closing instructions, protection action signals, etc.), and a signal output port (feeds back the status signal 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 (for example, including an optocoupler device and a relay), and performs opening and closing actions according to the instructions of the control unit 72.

[0089] The device body 100 is also provided with a connection operation unit 73 for realizing a manual closing operation component 731 (such as a button) and a manual opening operation component 732 (such as a button) for manual operation.

[0090] There are four pulse power detection units 71, and the signal input ends of the four pulse power detection units 71 are connected in sequence to the 24V opening input signal socket 81, the 24V closing input signal socket 83, the 48V opening input signal socket 82 and the 48V opening input signal socket 82 fixed on the device body 100; the 24V opening input signal socket 81 and the 48V opening input signal socket 82 share the negative end socket, and the 24V closing input signal socket 83 and the 48V closing input signal socket 84 also share the negative end socket, making the structure more compact.

[0091] The signal output ends of the four pulse power detection units 71 are all connected to the control unit 72. The pulse power detection unit 71 designed in the present application is composed of a diode, a Hall sensor, and a resistor and capacitor, wherein the high-power resistor is responsible for detecting the voltage, and then the Hall sensor performs the current detection of the loop. According to P=UI, when the external closing and opening pulse signal is input and meets the power requirement, the pulse power detection unit 71 collects the signal through the ADC interface of the control unit 72 and makes a judgment.

[0092] The control unit 72 is also connected to an opening output signal socket 85 and a closing output signal socket 86 fixed to the device body 100, and the test equipment is connected to the opening output signal socket 85 and the closing output signal socket 86 for receiving the feedback simulated circuit breaker status signal.

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

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

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

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

[0097] The device body 100 is provided with labels corresponding to the 24V opening input signal socket 81, the 24V closing input signal socket 83, the 48V opening input signal socket 82, the 48V opening 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 opening input signal socket 81 / 24V closing input signal socket 83 can be set with a +24V mark on the device body 100, and the 48V opening input signal socket 82 / 48V closing input signal socket 84 can be set with a +48V mark. The 24V opening input signal socket 81 and the 48V opening input signal socket 82 can be set with an opening input mark together.

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

[0100] The simulated circuit breaker and interface integrated device designed in this application for distribution automation testing has the following beneficial effects:

[0101] 1. Integrate a first aviation socket 1 with 26 pins and two second aviation sockets 2 with 10 pins, and connect multiple first interface sockets and second interface sockets to their respective interface sides, and mark them one by one, so that the power distribution terminal tester can be conveniently connected to the tested power distribution terminal through the first interface socket and / or the second interface socket. The interface module of the present application serves as a connection transfer module, which realizes the interface uniformity, so that the existing power distribution terminal tester and the power distribution terminal can be conveniently and safely connected through the interface module of the present application.

[0102] 2. In the analog circuit breaker module, a pulse power detection unit 71, a 48V voltage regulator unit 75 and a 24V voltage regulator unit 74 are designed 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 the distribution terminal, and improve adaptability.

[0103] 3. Integrate the interface module with the analog circuit breaker module to reduce the types of debugging equipment and improve work efficiency.

[0104] The above is an embodiment of the present application of a simulated circuit breaker and an integrated interface device for power distribution automation testing. The following is an embodiment of the present application of a simulated circuit breaker and an integrated interface device for power distribution automation testing. For details, please refer to Figures 1 to 6 .

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

[0106] Furthermore, if Figure 3 As shown, there is a common three-phase power socket 65 (connected to pins 1-3 of the second aviation socket 2) in the two groups of second interface sockets connected by the two second aviation sockets 2; the first control switch 66 is provided on the neutral line and the live line connected by the three-phase power socket 65 and the two second aviation sockets 2. 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 the first control switch 66 is provided on the neutral line to prevent mixing with the signal line of the banana socket, and at the same time, the first control switch 66 is added on the live line, which greatly improves safety.

[0107] Furthermore, a power supply battery (not shown in the figure) is also included. The power supply battery can be a lithium battery and is built into the device body 100.

[0108] The output end of the power supply battery is electrically connected to the interface module and the analog circuit breaker module respectively through the second control switch; an inverter module is installed on the line connecting the power supply battery to the interface module, which is used to convert the DC power output by the power supply battery into AC power and then transmit it to the interface module.

[0109] The power supply battery provides at least 3 hours of continuous power supply (depending on the battery capacity), ensuring that the device can still operate normally without external power. When there is no external power supply, the power supply battery can output the AC power required by the interface module through the inverter module, or provide the required DC power to the analog circuit breaker module.

[0110] Furthermore, a first switch operating component (not shown) connected to the first control switch 66 is provided on the device body 100 .

[0111] like Figure 5 As shown, the device body 100 is provided with a second switch operating component 91 connected to a second control switch (the second switch operating component 91 may be a knob component, and corresponding labels, such as battery and AC power, are provided on the device body 100. When the pointer of the second switch operating component 91 points to a corresponding label, it is in the corresponding switch control state. When it points to the battery label, it is in the battery use state; when it points to the AC power, it is in the external power supply state, and the power supply battery is charged while the external power supply is used).

[0112] Furthermore, if Figure 5 As shown, the device body 100 is also provided with a third switch operating component 92 connected to the inverter module. The third switch operating component 92 is a button component. When the power supply battery is used, after the inverter module is turned on by the third switch operating component 92, it is regarded as using the power supply battery to power the interface module.

[0113] Furthermore, if Figure 4 As shown, in order to facilitate interactive operations, the simulated circuit breaker module also includes an interactive unit 76 , and the interactive unit 76 is electrically connected to the control unit 72 .

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

[0115] The display 87 is a 1.8-inch liquid crystal display 87, and the interactive operation component 88 can be a digital encoder button EC11. The display 87 displays an interactive UI interface, and the delayed action time of the simulated circuit breaker can be set. EC11 is used as an interactive button. Rotating EC11 scrolls menus and numbers, and pressing EC11 is used for confirmation and saving operations.

[0116] Furthermore, the first interface socket, the second interface socket, the 24V opening input signal socket 81, the 24V closing input signal socket 83, the 48V opening input signal socket 82, the 48V opening input signal socket 82, the 24V power input socket 741 and the 48V power input socket 751 are all installed with an infrared radiation module (not shown in the figure) for detecting whether the corresponding plug is properly plugged in between itself and the corresponding matching plug.

[0117] Specifically, each interface socket can be provided with a detection through hole running through it along its own radial direction, and an infrared transmitter and an infrared receiver can be arranged at both ends of the detection through hole. When the matching plug is plugged into place, the infrared receiver will be blocked from receiving the infrared rays generated by the infrared transmitter, and the indicator light connected to it will light up, thereby indicating to the operator that the plug is not plugged into place, thereby ensuring the reliability of the connection.

[0118] It is also possible to increase the protection functions of the current and voltage ends by setting overcurrent protection at the current ends of the first and second interface sockets and setting overvoltage protection at the voltage ends to prevent equipment damage caused by misoperation or electrical fluctuations during debugging.
