Electromagnetic deicing system for high-voltage line insulator

The invention discloses an electromagnetic deicing system for a high-voltage line insulator, and relates to the field of power equipment operation and maintenance. The problem of how to provide a deicing device which does not affect the operation of a power grid is solved. The system comprises an electromagnetic induction power taking module, a rectification module, an inversion module, a radio frequency generation module, a detection module, a control module, a multi-band microwave emitter, M frequency selection wave-blocking rings and a relay protection module. The M frequency selection wave-blocking rings are divided into N groups; the N groups of frequency selection wave-blocking rings are respectively arranged on the N insulating layers of an insulator string; the frequency selectionwave-blocking rings on the same insulating layer are used for receiving electromagnetic waves of the same frequency band; the frequency bands of electromagnetic waves received by the frequency selection wave-blocking rings on
