[0028] In the above structure, the drive gear 13, located within the inner cavity of the locking seat 9, is driven by the knob 14 when the knob 14 is rotated. This rotation causes the moving rack 11 to move, allowing the locking plate 15 to enter the inner cavity of the equipment housing 1, thereby fixing the locking seat 9. The locking seat 9 then secures the fault-causing module 4 and the control terminal 5. The outer wall of the knob 14 is provided with anti-slip textures, which are evenly distributed in a ring on the outer wall of the knob.

Furthermore, under the action of the control terminal 5, it collects voltage and current signals in real time when a fault occurs, records waveform, amplitude, phase, and other characteristics, and compares them with the judgment results of the line selection device, thereby simulating various fault conditions. When it is necessary to install or remove the fault occurrence module 4 and the control terminal 5, the contact plate 16 at one end of the fault occurrence module 4 is inserted... The locking plate 15 is inserted into the inner cavity of the locking slot 8, and then the locking seat 9 is fixed in the inner cavity of the equipment box 1. By rotating the drive gear 13, the moving rack 11 can move under the action of the drive gear 13, thereby allowing the locking plate 15 to enter the inner cavity of the equipment box 1, thus fixing the locking seat 9.
