Description

Technical Field

[0001] The utility model belongs to the technical field of detection and measurement, and particularly relates to an opening and closing metering device integrated with wired communication. Background Art

[0002] A split-type current transformer is a device that converts voltage or current proportionally. Its function is to convert high voltage or high current proportionally into a standard low voltage (100V) or standard low current (5A or 10A, both rated values). This allows for the standardization and miniaturization of measuring instruments, protective devices, and automatic control equipment. Transformers can also be used to isolate high-voltage systems to ensure personal and equipment safety. The use of conventional transformers requires the use of electricity meters as components of CT-type electricity meters, that is, the open-close current transformer samples and then sends it to the electricity meter through the signal line. This use requires not only considering the installation position of the electricity meter transformer, but also increasing the space that needs to be reserved. In addition, a separate electricity meter is used in conjunction with an open current transformer to complete the corresponding use environment. In addition to its own power supply line and communication line, the electricity meter also needs to connect the transformer's sampling signal line to the electricity meter for sampling and analysis. Problems often encountered in this process are: 1. The current signal line between the transformer and the electricity meter may pass through many other devices when the customer actually uses it, and other devices may cause more interference to the signal line, resulting in some accuracy problems when the client actually uses it; 2. The transformer and the electricity meter are separated when the customer is in use. There is insufficient space in a smaller device, so a larger position needs to be reserved to place the electricity meter and the transformer.

[0003] Therefore, further improvements are made to the above problems. Utility Model Content
