Description

Technical Field

[0001] The utility model relates to the field related to transformer installation, in particular to a wiring tool for transformer installation. Background Art

[0002] Instrument transformers, also known as instrument transformers, are a general term for current transformers and voltage transformers. They can convert high voltage into low voltage and high current into low current, and are used in measurement or protection systems. Their main function is to proportionally convert high voltage or high current into standard low voltage or standard low current, so as to achieve standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. At the same time, instrument transformers can also be used to isolate high voltage systems.

[0003] The installation of the instrument transformer involves multiple steps. The wiring steps need to be based on the wiring requirements of the three-phase electricity meter. Connect the secondary sides of the voltage transformer (PT) and current transformer (CT). Note that the secondary side of the current transformer cannot be open circuited. The transformer and the power system must be effectively grounded. Use copper wire with sufficient cross-section for connection. Ensure that the grounding resistance meets the relevant standards.

[0004] However, in the existing technology, the wiring harness connection of the mutual inductor is usually manually operated. The worker holds the wire and connects the wire end to the corresponding point to fix it. However, holding the wire requires one hand free to operate, which easily affects the worker's holding tools or performing other operations. This is not only inefficient but also reduces the safety of operation. Therefore, we need to upgrade and transform the existing technology to overcome the existing problems and shortcomings.
