Multifunctional safety isolation device for transformer substation

The multifunctional safety isolation device comprises a protective cover, a fixing part is arranged on the side face of the protective cover, an opening is formed in the front face of the protective cover, a long-strip-shaped guide rail is arranged on the opening in the length direction of the protective cover, and limiting parts are arranged at the two ends of the guide rail respectively. At least one sliding plate with damping is movably arranged on the guide rail, and a warning board is detachably arranged on the sliding plate. According to the invention, the situation that operation equipment and maintenance equipment are on the same screen on the protection screen in the transformer substation is effectively avoided, accidents caused by mistakenly touching the operation equipment during working are prevented, the original isolation modes of cloth, paper isolation, adhesive tape winding and the like are replaced, the defects of current general safety isolation measures are overcome, the maintenance effici
