Description

Technical Field

[0001] The invention discloses an intelligent fuse with a combined coil type wireless current detection function, and relates to the field of intelligent fuses. Background Art

[0002] The fuse is an important electrical protection device. Its main function is to cut off the circuit by melting itself when an overload or short circuit occurs in the circuit, thereby preventing further damage to electrical equipment and lines. The fuse is mainly composed of three parts: the fuse element, the shell and the support. The fuse element is the core part of the fuse. It is a metal conductor made of fusible material. When the current in the circuit exceeds the specified value, the fuse element will melt due to heat, thereby cutting off the circuit. The shell is used to protect the fuse element from the influence of the external environment, and at the same time plays the role of supporting and fixing the fuse element. The support is used to fix the fuse element in the circuit to ensure that the fuse element can work stably. As a vital protection device in the power system, the fuse element's main function is to quickly cut off the current when an overload or short circuit occurs in the circuit to prevent equipment damage or fire and other safety accidents. However, if the fuse element cannot transmit its usage status to the intelligent terminal in the substation in real time, it will bring a series of serious problems.

[0003] This will result in the power operation and maintenance personnel being unable to obtain the real-time status information of the fuse in time, and thus unable to accurately monitor and evaluate the operating status of the power equipment. As an important part of the power line, the stability of the fuse is directly related to the safety and stability of the entire power system. If the fuse fails or is abnormal, and the operation and maintenance personnel fail to discover and deal with it in time, the risk of power accidents will increase, and may even cause large-scale power outages, causing great inconvenience to people's production and life. Therefore, our unit is in urgent need of an intelligent fuse with a combined coil wireless current detection function to solve the above problems. Summary of the invention
