Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment safety, and in particular to an electrical equipment operation safety verification system and method. Background Art

[0002] The safety check of electrical equipment operation is a key link to ensure the safe operation of the electrical system. It includes two aspects: safety during maintenance and safety during operation. Safety check during maintenance mainly refers to a series of preventive measures taken when the equipment is powered off for maintenance or repair to prevent accidental electric shock, fire or other electrical accidents. This usually involves safety measures such as power off, locking / tagging equipment, and using personal protective equipment. Safety check during operation refers to monitoring and evaluating the performance and status of the equipment under normal working conditions to ensure that it operates stably within the specified parameter range and avoid safety problems caused by overload, short circuit or other faults. The importance of safety testing is self-evident. It is not only related to the life safety and physical health of personnel, but also involves the protection of equipment assets, the guarantee of production efficiency, and the safe and stable operation of the power grid. Effective safety check can timely discover potential safety hazards, prevent accidents, reduce economic losses, and improve the overall safety management level of the enterprise.

[0003] Although existing electrical equipment safety detection methods, such as traditional current, voltage and temperature monitoring, can ensure the safe operation of equipment to a certain extent, they often have certain limitations. For example, a single monitoring parameter may not be able to fully reflect the operating status of the equipment, and for some complex failure modes, traditional detection methods may not be able to identify and warn in time. In addition, the existing detection system lacks intelligent and automated alarm mechanisms, and is not comprehensive. It does not comprehensively consider the equipment conditions during maintenance and operation and provide equipment safety warnings based on this.

[0004] In view of this, a system and method for verifying the safety of electrical equipment operation is needed. Summary of the invention

In addition, combined with intelligent alarm operations, an alarm can be automatically triggered when an abnormality is detected, and relevant personnel can be notified in time to take countermeasures, thereby greatly improving the efficiency and response speed of safety management.

[0058] In this step, the method for collecting insulation resistance and grounding resistance is as follows:

[0059] 1. Collection of insulation resistance:

[0060] - Use a megohmmeter (megger) to measure the insulation resistance of electrical equipment. This is an indicating instrument specially designed for testing large resistances, and the unit is usually megohm (MΩ).

[0061] - Before measuring, make sure the device is powered off and fully discharged to avoid electric shock hazards or measurement errors.

[0073] S4: Determine whether to output an alarm signal based on the verification results in the maintenance state and the comparison results when the equipment is in the operating state, as well as the comprehensive evaluation score.

[0074] In summary, the present invention integrates the safety during maintenance and the safety during operation to derive a comprehensive index, which can then more comprehensively evaluate the safety status of electrical equipment. This method can not only integrate multiple monitoring parameters to provide a more accurate equipment status assessment, but also predict potential failures and risks through advanced data analysis technology.
