[0003] There are many deficiencies in the existing related technologies in protecting energy storage motors. Traditional protection systems often require major changes to the original control circuit of the energy storage motor. Such changes not only increase the difficulty of installation, but may also introduce new unstable factors, affecting the normal operation of the motor.

There is often a problem of untimely detection, resulting in the protection measures not being able to play a role quickly and effectively. The protection modules in the existing technology usually lack an integrated design, resulting in poor system integrity, which is not conducive to the development trend of standardization and modularization. More importantly, the existing technology has failed to effectively solve how to achieve real-time monitoring and rapid alarm of faults without changing the original control circuit of the motor to ensure the safe operation of the motor and the continuous power supply of the system.

For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0024] Example 1, reference Figure 1, as an embodiment of the present invention, provides a general protection method for a circuit breaker energy storage motor, comprising:

[0025] S1: Design and install a set of integrated packaged protection modules, which are connected in series to the front-end circuit of the energy storage motor without changing the original control circuit of the energy storage motor.

[0026] Furthermore, the protection module includes a structure of a universal packaging design, which includes an input terminal and an output terminal, and is directly connected in series in the front-end circuit of the energy storage motor without changing the original control circuit of the energy storage motor.

[0027] The protection module is suitable for energy storage motor protection of circuit breakers of different models, and is connected to the control circuit in series, providing additional protection functions without affecting the original circuit configuration.

[0028] It should be noted that by designing and installing a set of integrated packaged protection modules and connecting them in series to the front-end circuit of the energy storage motor, the original control circuit of the energy storage motor is not changed, ensuring that the addition of the protection module will not interfere with the original control logic and circuit design of the energy storage motor, thereby maintaining the stability and reliability of the motor system. Through the integrated packaging design, the installation of the protection module is easier, the error rate during the installation process is reduced, and the overall installation efficiency of the system is improved. The series connection method of the protection module enables it to monitor the current state of the front-end circuit of the motor in real time, providing a basis for subsequent current collection and fault monitoring. Due to the versatility and packaging of the protection module, the protection system can be easily adapted to different models of circuit breaker energy storage motors, which improves the scope of application and flexibility of the system, provides users with a wider range of choices, improves user experience and reduces maintenance costs.

[0029] S2: Configure a current acquisition module and a fault monitoring module in the protection module to collect current data of the energy storage motor in real time and monitor whether overcurrent or timeout faults occur.

[0030] Furthermore, the current acquisition module includes a sensor device for real-time acquisition of the running current of the energy storage motor. The sensor device transmits the current signal to the fault monitoring module. The current acquisition module continuously acquires the running current of the motor and provides the collected current data to the fault monitoring module.

[0031] It should be noted that the fault monitoring module includes an overcurrent detection unit and a timeout detection unit. The overcurrent detection unit and the timeout detection unit analyze and judge the operating status of the motor according to preset threshold parameters. When the fault monitoring module detects that the current exceeds the set overcurrent threshold or the operating time exceeds the timeout setting value, the energy storage motor is stopped through contact control.

[0032] It should also be noted that the overcurrent detection unit is an important part of the motor protection system. The specific steps are as follows: In the current sensing stage, the overcurrent detection unit uses the built-in current transformer or Hall sensor to perform non-contact monitoring of the current in the motor power line. These sensors can convert the current intensity into a corresponding electrical signal to provide basic data for subsequent processing. Signal conditioning becomes a necessary step because the original sensing signal is often weak and may contain noise. The signal is amplified by an operational amplifier and high-frequency interference is removed by a low-pass filter to ensure the accuracy and stability of the signal and prepare for signal comparison. In the signal comparison stage, the conditioned current signal is compared with the preset overcurrent threshold. This step is completed by the comparison circuit, which monitors in real time whether the signal exceeds the established threshold. Once an exceeding situation occurs, a trigger signal is immediately output. The output trigger signal is a direct instruction for the protection action. When the comparison circuit detects an overcurrent condition, a trigger signal is immediately generated. The signal is transmitted to the protection action execution circuit and protective measures are taken. The execution of the protection action is the key link in the entire process. After receiving the trigger signal, the execution circuit acts quickly to cut off the power supply of the motor to prevent the current from continuing to rise, thereby effectively protecting the motor from damage. This step usually involves the disconnection operation of a mechanical or electronic switch. The alarm and feedback mechanism provides closed-loop control for the system. The overcurrent detection unit will activate the alarm system while triggering the protection action, and notify the operator through an audible and visual alarm or control system. The unit will also record fault information, including the time and current value of the overcurrent, to facilitate subsequent analysis and system optimization.

[0033] It should also be noted that the timeout detection unit ensures that the motor operates within a safe operating time to prevent damage caused by long-term operation. The specific steps are as follows: When the system is initialized, the timeout detection unit will set an accurate time base, which is achieved through a built-in high-precision clock or an external clock signal, to provide a reliable timing starting point for subsequent operating time monitoring. After the motor is started, the unit immediately starts timing and monitors the motor's operating time in real time. This process is completed by the timer or the built-in timing function of the microprocessor, ensuring the accurate accumulation of time data. As the motor continues to run, the timeout detection unit compares the real-time accumulated operating time with the preset timeout threshold, which is based on the motor's safe operating specifications. It is pre-set that once the accumulated time exceeds this threshold, the unit will make a timeout judgment, believing that the motor may be in an unsafe operating state. After the timeout judgment is established, the timeout detection unit quickly triggers the protection action, cuts off the motor power supply through the control circuit, prevents the motor from continuing to run, and thus avoids possible damage. The immediate execution of the protection action ensures that the motor can be protected in time in the event of a timeout. The timeout detection unit will also activate the alarm system, notify the operator of the motor overtime operation through the sound and light alarm or control system, and provide detailed fault records, including the time when the timeout occurred and the motor status, which not only facilitates the operator to respond in time, but also provides valuable data for subsequent fault analysis and system maintenance.

[0034] It should also be noted that a current acquisition module and a fault monitoring module are configured in the protection module to collect the current data of the energy storage motor in real time and monitor whether overcurrent or timeout faults occur. Through the real-time collection of current data, abnormal conditions in the operation of the motor can be discovered in time, so that preventive measures can be taken in advance. The setting of the fault monitoring module can analyze the collected current data in real time to determine whether there is an overcurrent or timeout fault. The real-time monitoring mechanism improves the fault response speed of the system, ensures that measures are taken as soon as a fault occurs, and effectively prevents the expansion of the fault. This step realizes comprehensive monitoring of the operating status of the energy storage motor through the combination of current acquisition and fault monitoring, which not only improves the safety performance of the motor system, but also reduces the downtime and maintenance costs caused by faults, making the protection system highly intelligent and automated, reducing manual intervention, and improving production efficiency and system management level.

[0035] S3: Set up an alarm mechanism to trigger an alarm signal based on overcurrent detection and timeout detection results.

[0036] Furthermore, the alarm mechanism includes an alarm signal trigger, which is connected to the fault monitoring module. When the fault monitoring module detects an overcurrent or timeout fault, an alarm signal is triggered, and the alarm signal is transmitted to the maintenance system or monitoring equipment through the circuit.

[0037] It should be noted that the overcurrent detection includes an overcurrent detection unit which is an adjustable action current threshold setting device. The action current threshold setting device adjusts the action current threshold of the energy storage motor through a knob to adapt to the protection requirements of energy storage motors of different models. When the current value detected by the current acquisition module exceeds the set overcurrent threshold, the overcurrent detection unit in the fault monitoring module will trigger a protection response and stop the operation of the energy storage motor.

[0038] It should also be noted that the timeout detection includes a timeout detection unit which is an adjustable timeout setting device. The adjustable timeout setting device adjusts the allowable time range of the energy storage process through a knob to meet the operating requirements of different energy storage motors. When the running time of the energy storage motor exceeds the set timeout threshold, the timeout detection unit triggers the emergency stop control to stop the motor immediately and lock the energy storage motor starting device at the same time.

[0039] It should also be noted that an alarm mechanism is set up to trigger an alarm signal based on the overcurrent detection and timeout detection results. The setting of the alarm mechanism enables the system to immediately send out an alarm signal when an overcurrent or timeout fault is detected, reminding the operator or maintenance personnel to take corresponding emergency measures, thereby shortening the fault handling time and reducing the impact of the fault on production. The alarm signal is transmitted to the maintenance system or monitoring equipment through the circuit, thereby realizing the rapid transmission of fault information, enabling maintenance personnel to quickly locate the source of the fault and improving the efficiency of fault handling. The introduction of the alarm mechanism enhances the safety monitoring capability of the energy storage motor system, and effectively prevents the occurrence of safety accidents through timely detection and alarm of potential dangers, thereby ensuring the safety of personnel and equipment. The scalability and compatibility of the system are fully considered, so that the alarm signal can be seamlessly connected with the existing monitoring system or maintenance system, thereby improving the integration and intelligence level of the entire motor protection system.

[0040] Embodiment 2 is an embodiment of the present invention, which provides a universal protection method for energy storage motors of circuit breakers. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0041] Firstly, three different types of energy storage motors were selected for the experiment, with three units of each type, to evaluate the applicability and performance of the protection module on different motor models. The protection module was installed with a universal packaging design, including input terminals and output terminals, which can be directly connected in series in the front-end circuit of the energy storage motor without changing the original control circuit of the motor, ensuring the easy installation of the module and minimal interference to the original circuit of the motor. A current acquisition module and a fault monitoring module were configured in the protection module. The current acquisition module is composed of a high-precision sensor device, which is responsible for real-time collection of motor operating current data. The fault monitoring module includes an overcurrent detection unit and a timeout detection unit, which analyzes and judges the motor operating status according to the preset threshold parameters. When the current exceeds the set overcurrent threshold or the operating time exceeds the timeout setting value, the fault monitoring module is automatically started. The fault monitoring module will stop the motor through contact control. The present invention also includes an alarm mechanism, which is connected to the fault monitoring module. Once an overcurrent or timeout fault is detected, the alarm signal trigger will immediately trigger an alarm signal and transmit it to the maintenance system or monitoring equipment through the circuit so that maintenance personnel can quickly take corresponding measures. During the experiment, each model of motor was tested multiple times, and the key parameters of overcurrent threshold, timeout threshold, actual operating current, operating time, overcurrent detection response time, timeout detection response time and alarm signal transmission time were recorded. In summary, the present invention shows innovation and practicality in the field of circuit breaker energy storage motor protection, improves the safety performance of the motor system, reduces maintenance costs, and enhances user experience, and has broad application prospects.
