Over-temperature indicating device for electrical equipment

The utility model relates to the technical field of electrical equipment, in particular to an over-temperature indicating device for electrical equipment, which is simple to operate, economical, practical, wide in application range, high in reliability and capable of monitoring the temperature of external insulation of the electrical equipment according to the color change of thermochromic ink. The two ends of the ink panel are connected with the clamping plate assemblies in a rotating mode through the torsion springs. By changing the opening angle of the clamp plate assembly, the clamp plateassembly is suitable for wire clamps of different sizes. meanwhile, a groove is formed in the surface of the ink panel to form an area for smearing the thermochromic ink layer; the device is fixed ata key part of electrical equipment; a thermochromic ink layer does not need to be directly coated on the surface of the electrical equipment; the surface temperature of the electrical equipment is warned and indicated by utili
