Technical Field
[0001] The present invention relates to the technical field of circuit monitoring, in particular to an online monitoring device for a circuit breaker used in a building. Background Art
[0002] A high-voltage circuit breaker is an electrical device that can open, close, and carry normal current in operation, and can carry, close, and open abnormal currents (such as short-circuit currents) within a specified time. Its working characteristic is that it can instantly change from a conducting state to an insulating state or from an insulating state to a conducting state. In the power system, it is of practical significance to effectively use the control and protection functions of high-voltage circuit breakers to ensure the safe and reliable operation of the power grid. In the power system, vacuum circuit breakers are important protection devices, and their stability and reliability are directly related to the safe operation of the entire power grid. In order to ensure the normal operation of vacuum circuit breakers, the existing technology has developed a variety of online monitoring devices, which usually have the function of monitoring parameters such as current, voltage, and temperature. However, the existing online monitoring devices still have the following significant defects: High Installation Complexity: Many existing online monitoring devices require specialized mounting structures or circuit breaker modifications, which not only increases installation difficulty but also may affect the original structure and performance of the circuit breaker. Some monitoring devices must be mounted on the circuit breaker surface through mechanical fastening or welding, which is very complex in practice and requires professional operation.
[0003] Limited Applicability: Due to limitations in their installation methods, many online monitoring devices cannot be widely used across a wide range of vacuum circuit breakers. These devices are often designed for specific circuit breaker models, lacking sufficient versatility to adapt to the diverse range of circuit breaker equipment in power systems. Due to the significant structural differences between circuit breakers, the application scenarios of existing monitoring devices are limited, making them difficult to meet practical needs.
[0004] Limited monitoring capabilities: Existing online monitoring devices are often limited to monitoring a single or limited set of parameters, failing to provide comprehensive information about the device's status. In particular, existing devices typically monitor only the external temperature of the circuit breaker and are unable to monitor changes in internal temperature or insulation status in real time, making it difficult to detect potential circuit breaker failures.
[0005] In summary, existing online monitoring devices for building circuit breakers still have numerous shortcomings in terms of installation complexity, applicability, comprehensive monitoring functionality, data transmission security, and intelligent management capabilities. These shortcomings prevent them from fully meeting the intelligence, reliability, and safety requirements of modern power systems. Therefore, a more advanced online monitoring device is urgently needed to address these issues and improve circuit breaker operation and management.

It should be noted that the embodiments of the application and the features in the embodiments can be combined with each other without conflict.
[0022] It is understood that the description is only exemplary and is not intended to limit the scope of the application.
[0023] The application will be described in detail below in combination with the drawings. Figures 1-6Some embodiments of the application provide an online monitoring device for an electrical circuit breaker.
[0024] In one possible implementation of the application, an online monitoring device for an electrical circuit breaker is provided, which includes a monitoring sticker box 200 with a plurality of permanent magnetic stickers 210 on its surface. Through the permanent magnetic stickers 210, the monitoring sticker box 200 can be firmly magnetically attached to the surface of the vacuum circuit breaker 100, achieving convenient installation and removal without any modification to the circuit breaker body.
[0025] The monitoring sticker box 200 is equipped with a monitoring controller 250 and an independent power supply, and the monitoring controller 250 is built-in with a remote control unit. The remote control unit contacts the control knob on the surface of the vacuum circuit breaker 100 through the control push rod 242, thereby achieving remote control of the vacuum circuit breaker 100. The monitoring sticker box 200 is also equipped with a monitoring slot 240, and the control knob on the surface of the vacuum circuit breaker 100 is sleeved on the inside of the monitoring slot 240. The monitoring slot 240 is equipped with a photoelectric detection switch 241 inside, which is used to sense the state of the control knob on the surface of the vacuum circuit breaker 100 and transmit the detected signal to the monitoring controller 250, thereby achieving real-time monitoring of the state of the circuit breaker.
[0026] In addition, the upper and lower ends of the monitoring sticker box 200 are respectively provided with a first electrode insert 220 and a second electrode insert 230, and the two electrodes are in contact with the surface electrodes of the incoming and outgoing lines of the vacuum circuit breaker 100 connected at the upper and lower ends, thereby achieving electrical connection. The monitoring controller 250 is integrated with multiple monitoring modules inside, including current and voltage monitoring modules, temperature monitoring modules, insulation monitoring modules, and communication modules.
[0027] In this implementation, the current and voltage monitoring modules include current sensors and voltage sensors, respectively, for monitoring the current and voltage parameters of the incoming and outgoing lines of the vacuum circuit breaker 100. The data of these sensors is used to determine the working state of the circuit breaker to ensure that the circuit breaker operates within a normal range.
[0028] The temperature monitoring module includes temperature sensors installed on the surface or inside of the vacuum circuit breaker 100, which are used to monitor the temperature changes of the circuit breaker in real time. When the temperature exceeds a set threshold, the temperature monitoring module will automatically trigger an over-temperature alarm signal to prevent the equipment from being damaged due to overheating.
[0029] The insulation monitoring module includes insulation resistance measuring devices and leakage current detectors, which are used to periodically detect the insulation state of the vacuum circuit breaker 100. Through this module, insulation faults can be discovered and prevented in a timely manner, thereby improving the safety and operational reliability of the equipment.
[0030] The communication module is used to exchange data with the remote control center via wireless communication to achieve real-time monitoring and remote control of the vacuum circuit breaker 100. During the communication process, the integrated data encryption unit can ensure the security of data transmission and prevent external attacks and data leakage.
[0031] To ensure the long-term stable operation of the monitoring cassette 200, the monitoring controller 250 also includes a battery management module. This module, consisting of a battery monitoring unit and a charging management module, monitors the power level and health status of the independent power supply in real time and issues a warning signal when the battery is low.

[0032] The monitoring box 200 has guide grooves on its upper and lower sides, respectively, for guiding the first and second electrode tabs 220 and 230. A slider 221 is fixedly attached to the surface of each electrode tab, allowing it to slide smoothly into position.

[0034] Through the above-mentioned embodiments, the present invention can realize comprehensive online monitoring of the vacuum circuit breaker 100 and maintain real-time data interaction with the remote control center through wireless communication, thereby improving the intelligent management level of the equipment and the safety of operation.
[0035] The working principle and use process of the present invention: The present invention relates to an online monitoring device for building circuit breakers. Its primary operating principle is to achieve real-time monitoring and remote control of the circuit breaker by attaching a monitoring sticker box 200 to the surface of a vacuum circuit breaker 100. Specifically, the monitoring sticker box 200 is provided with multiple permanent magnetic stickers 210, which securely attach the monitoring sticker box 200 to the surface of the vacuum circuit breaker 100 through magnetic attraction, eliminating the need to modify the circuit breaker itself. This design ensures convenient installation and device independence.
[0036] The monitoring box 200 houses a monitoring controller 250, which controls the circuit breaker's operating status via a built-in remote control unit. The monitoring controller 250 integrates multiple monitoring modules, including a current and voltage monitoring module, a temperature monitoring module, an insulation monitoring module, and a communication module. These modules monitor the circuit breaker's electrical parameters, temperature, insulation status, and other parameters, and transmit this data in real time to a remote control center via wireless communication.
[0037] During monitoring, the photoelectric detection switch 241 within the monitoring slot 240 senses the status of the control buttons on the surface of the vacuum circuit breaker 100 and transmits the signal to the monitoring controller 250, enabling real-time monitoring of the circuit breaker's status. The monitoring controller 250 uses current and voltage sensors, temperature sensors, and insulation detectors to monitor the circuit breaker's operating status in real time and issues an alarm signal if an anomaly occurs.
[0038] like Figure 6 As shown, the monitoring device of the present invention can fix several vacuum circuit breakers 100 through the fixing row 110. Each monitoring sticker box 200 can be arranged on the surface of the vacuum circuit breaker 100 to be monitored, thereby realizing centralized monitoring and management of multiple circuit breakers.
[0039] Usage Process Install monitoring device: according to Figure 6 As shown, the vacuum circuit breaker 100 is fixed at a designated position by a fixing row 110. Then, a monitoring sticker box 200 is firmly attached to the surface of each vacuum circuit breaker 100 by a permanent magnetic sticker 210. Each monitoring sticker box 200 is arranged in a one-to-one correspondence with the corresponding vacuum circuit breaker 100.
[0040] Equipment initialization: After installation is completed, start the monitoring controller 250 in the monitoring box 200. At this time, the monitoring controller 250 will initialize the current state of the vacuum circuit breaker 100 to ensure that all sensors are working properly and establish a communication connection with the remote control center.
[0041] Monitoring Process: During normal operation, the current and voltage monitoring modules, temperature monitoring modules, and insulation monitoring modules within the monitoring box 200 collect real-time information on the circuit breaker's electrical parameters, temperature changes, and insulation status. The photoelectric detection switch 241 continuously senses the status of the control buttons on the surface of the vacuum circuit breaker 100 and transmits this data to the monitoring controller 250.
[0042] Data transmission and remote monitoring: The communication module built into the monitoring controller 250 transmits collected data to the remote control center in real time via wireless communication. Operators at the remote control center can view the operating status of multiple vacuum circuit breakers 100 in real time through the monitoring platform and perform remote control as needed.
[0043] Abnormality handling and alarms: If any abnormality is detected during monitoring, such as current or voltage fluctuations, temperature exceeding limits, or insulation failure, the monitoring controller 250 immediately triggers an alarm signal and transmits the alarm information to the remote control center via the communication module. Operators can take timely measures based on the alarm information to prevent further escalation of the circuit breaker failure.
[0044] Maintenance and Record Analysis: This system also features fault recording and analysis capabilities, automatically recording fault information during circuit breaker operation and analyzing historical data. The analysis results generate operational reports for maintenance personnel to reference, helping them optimize equipment maintenance strategies and extend equipment life. Maintenance personnel can also access historical fault records and analysis reports in real time through a remote control center, ensuring efficient equipment management.
[0045] Through the above working principle and usage process, the present invention can effectively improve the monitoring efficiency and management level of the circuit breaker, and ensure the safe and reliable operation of the circuit breaker in a complex environment.
