Description

Technical Field

[0001] This disclosure relates to the field of circuit breaker technology, specifically to a circuit breaker detection device, system, and method. Background Technology

[0002] High-voltage circuit breakers are an important component of distribution network systems, serving to interrupt or close the no-load current and load current in high-voltage circuits, and providing protection through relays in the event of system faults. When a high-voltage circuit breaker trips, the traditional method for locating its trip location is to first manually estimate the trip location based on the power outage area, then systematically check and verify each potentially tripped circuit breaker on-site, and finally manually determine the trip location.

[0003] With technological advancements, fault line addressers have emerged on the market. These are small devices, about the size of a light bulb. Before use, they need to be hung at intervals on the conductors, especially at line nodes and branches. When a circuit breaker trips and the line loses power, the inner core inside the transparent cover of the line addresser flips, changing from white to red. Fault inspectors can then locate the tripped circuit breaker by following the lines where the addressers are installed and the inner core has turned red. Although this method of locating the tripped circuit breaker by observing the status of the fault addresser is more accurate than the traditional manual method and reduces labor costs, it requires installing fault addressers on multiple important lines, resulting in a large number of fault addressers being needed. Lines without these addressers cannot be identified, significantly increasing the investment cost of the device. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Example 1

[0042] Please refer to Figure 1 The present application provides a circuit breaker testing device, wherein each circuit breaker is provided with a corresponding testing device, and the testing device includes:

[0043] The proximity switch sensor module is configured to acquire the circuit breaker's opening signal and convert it into an optocoupler signal.

[0044] Optocoupler isolation module, configured to convert optocoupler signals into level signals;

[0045] The main control module is configured to receive level signals and convert them into trip indication signals, and then send the trip indication signals to the server through the communication module; the trip indication signals include trip time information and circuit breaker identification code information.

[0046] In this embodiment, the proximity switch sensor module is configured to collect the circuit breaker's opening signal and convert it into an optocoupler signal;

[0047] Furthermore, the proximity switch sensor module includes an inductive proximity switch, the type of which is, for example, an NPN type inductive proximity switch; when metal approaches the detection surface of the inductive proximity switch, the inductive proximity switch transmits the optocoupler signal to the optocoupler isolation module through a wire.

[0048] Optocoupler isolation module, configured to convert optocoupler signals into level signals;

[0049] Furthermore, the level signal is a low-level signal;

[0050] The main control module is configured to receive level signals and convert them into trip indication signals, and then send the trip indication signals to the server through the communication module; the trip indication signals include trip time information and circuit breaker identification code information.

[0051] Furthermore, the main control module includes a main control chip, the type of which is, for example, an STM32F103ZET6 chip;

[0052] The communication module is configured to send tripping alert signals to the server.

[0053] Furthermore, the communication module is the SIM800C communication module;

[0054] Furthermore, it also includes: a power supply module configured to supply power to the proximity switch sensor module, temperature sensor module, optocoupler isolation module, main control module, communication module and circuit breaker;

[0055] Furthermore, the power supply module includes: a solar panel, a lithium battery, and a boost module;

[0056] Solar panels, which are used to power lithium batteries;

[0057] Lithium batteries, such as 18650 lithium batteries, have a voltage of 3.7V and are used to power the entire system.

[0058] Boost modules, such as DC-DC boost modules, are used to boost voltage to the operating voltage required by each module.

[0059] Furthermore, an inductive proximity switch is installed in front of the circuit breaker trip pointer. When the circuit breaker trip pointer moves, it will block the inductive proximity switch. After the inductive proximity switch detects an object in front, it will output a low-level signal to the main control module (STM32F103ZET6 chip). After the main control module detects the low level from the inductive proximity switch, it will send a pre-set code (which can be set arbitrarily, but to prevent duplication, it is usually set to the serial number of the STM32F103ZET6 chip) to the server via the GPRS of the SIM800C communication module. The server receives the signal sent by the main control module.

[0060] Furthermore, the main control module uses the STM32F103ZET6 series chip, and the hardware driver within the chip is written in C language. The power supply module uses a solar panel to charge a 3.7V 18650 lithium battery. The 18650 lithium battery is directly connected to the positive and negative terminals of the STM32F103ZET6 chip to power the chip. Two boost modules are used: one boost module raises the 3.7V voltage to 12V to power the optocoupler isolation module, and the other boost module raises the 3.7V voltage to 24V to power the inductive proximity switch. The PB5 pin of the STM32F103ZET6 chip is used as a low-level input terminal and connected to the OUT terminal of the optocoupler isolation module to receive the low-level signal transmitted from the optocoupler isolation module. After receiving the low-level input from the PB5 pin, the STM32F103ZET6 chip transmits the signal to the SIM800C communication module through serial port 3. The SIM800C communication module then uses its GPRS function to send the information to the server.

[0061] The circuit breaker tripping notification method is as follows:

[0062] S11. Collect the circuit breaker's opening signal through the proximity switch sensor module and convert it into an optocoupler signal;

[0063] S12. The optocoupler signal is converted by the optocoupler isolation module to obtain a level signal;

[0064] S13. The main control module receives the level signal and converts it into a trip indication signal, and the communication module sends the trip indication signal to the server. The trip indication signal includes trip time information and circuit breaker identification code information.

[0065] like Figure 1 As shown, it also includes: a temperature sensor module, which is connected to the main control module via a signal. The temperature sensor module is configured to collect the temperature information of the circuit breaker and convert it into a temperature signal.

[0066] The main control module is configured to receive temperature signals from the temperature sensor module at a set frequency and send the temperature signals to the server via the communication module.

[0067] Furthermore, the temperature sensor module includes a temperature sensor;

[0068] Furthermore, the temperature sensor probe is installed at the connection between the circuit breaker and the wire, or other locations where temperature measurement is required. The output of the temperature sensor module is connected to the PD12 pin of the STM32F103ZET6 chip, and the signal is transmitted to the SIM800C communication module through the serial port 3 of the STM32F103ZET6 chip. The GPRS function of the SIM800C communication module sends the information to the server, thus achieving the function of monitoring sensitive temperature points on the circuit breaker and providing a basis for equipment operation and maintenance.

[0069] The method for detecting circuit breaker temperature is as follows:

[0070] S21. Obtain the temperature signal of the circuit breaker through the temperature sensor module;

[0071] S22. The main control module acquires the temperature signal and sends it to the server through the communication module.

[0072] Furthermore, it also includes: relays, which are connected to the main control module, and the control terminal of the relays is connected to the low-voltage control circuit of the circuit breaker;

[0073] Furthermore, connect the control terminal of the relay to the power supply of the circuit breaker's manual control switch, and connect the signal input terminal of the relay to the PD0 pin of the STM32F103ZET6 chip.
