description The invention provides a transformer substation hard pressing plate state self-diagnosis detection box which comprises two symmetrically-arranged metal screw rods, a pressing plate feeding and retreating mechanism is arranged between the upper portions of the two metal screw rods, and a self-diagnosis detection box is arranged between the lower portions of the metal screw rods, a detection circuit formed by connecting a diode, a button battery, an LED lamp and a voltage type relay in series is arranged in the self-diagnosis detection box, and the detection circuit, the two metal screw rods and the pressing plate throwing and withdrawing mechanism form a closed current path. The device is simple in structure, ingenious in design and convenient to use, the detection circuit is switched on and switched off by opening and closing the metal connecting piece of the hard pressing plate, the LED lamp is turned on or turned off, and the contact condition of the metal connecting piece of the hard pressing plate and the
