Embodiment Construction
[0024] Such as figure 1 As shown, a kind of cable breakpoint fault fast finding instrument described in the embodiment of the present invention includes a clamp-type housing and a circuit board. The circuit board includes an integrated circuit, a resistor, a capacitor, a triode and a light-emitting diode. A pin, resistors R1, R2, capacitor C1 and an integrated circuit form an integrated amplifier circuit, resistor R3 is a sensitivity adjustment resistor, resistor R5 is a bias resistor for the base of the triode, and resistor R6 is a current-limiting resistor for a light-emitting diode. battery and sensors.
[0025] Such as figure 2 Shown, a kind of cable breakpoint fault fast finding method, it comprises the following steps:
[0026] 1) Disconnect the power supply: disconnect the circuit breaker 3 in the relay power supply box 6 for supplying power to the reel and trolley motor;
[0027] 2) Judgment: use a multimeter to measure the resistance of the motor at the connection...
