Protection circuit used for remote sudden stop control

The utility model discloses a protection circuit used for remote sudden stop control, and is characterized in that the structure of the protection circuit is that a sudden stop control unit is connected with an optical fiber signal receiving unit through two optical fiber channels, and the optical fiber signal receiving unit controls a distribution control unit to cut off pre-stage power supply of high-voltage energy storage equipment. By adoption of the structure, the protection circuit has the advantages that the protection circuit is simple in whole circuit design and high in reliability, and compared with electric cables, transmission distance of optical cables is longer, transmission speed is faster, and the optical cables are not influenced by external electromagnetic field and electromagnetic radiation; and remote state confirmation can be carried out after a sudden stop control switch is pressed and the sudden stop control switch is recovered, a sudden stop control signal can be recovered only when a
