Description

Technical Field

[0001] The utility model relates to the technical field of a test bench for electric power equipment, and more particularly to a multi-station intelligent electric energy meter data extraction workbench. Background Art

[0002] Fire accidents often result in severe damage to the scene and the loss of evidence, making investigations extremely difficult. However, electronic data from the fire scene and its surroundings can objectively and truthfully record and reflect the actual conditions before and during the fire. This digitally stored, processed, and transmitted data, capable of proving the facts of the case, has a strong probative value and is a key to uncovering the truth behind the fire.

[0003] Currently, the collection and analysis of this type of data in fire investigations is largely manual. In the past two years, however, attention has focused on devices like smart meters. Smart meters are key components of smart grid systems, objectively providing historical and real-time electricity usage data and capturing relevant anomaly data immediately. Fire investigators can analyze the current, voltage, and other data collected by meters to determine if there were overcurrent, overload, poor contact, or short circuits before and after a fire, providing a new approach for analyzing the time and cause of a fire. Therefore, extracting data from smart meters is crucial for fire investigations.

[0004] However, smart energy meters come in a variety of types, including single-phase, three-phase, three-phase, three-wire, three-phase, four-wire, three-phase, mutual inductive, and three-phase direct meters, and they also come in a variety of voltage levels. Currently, testing smart energy meters requires connecting a voltage conductor to the meter's wiring terminals. Due to the wide variety of meters, different types of smart energy meters have different wiring methods, requiring specialized knowledge to operate. Furthermore, wiring must be performed for each test, making the process cumbersome and inefficient.
