However, for the detection of the fault condition of the broken wire, when the test pencil is used for detecting the two ends of the broken wire, as the neon tube of the test pencil emits light when the voltage reaches more than 60V, the voltage at the two ends of the broken wire cannot be determined, and generally only the information about whether the two ends of the broken wire are electrified can be obtained, and the fault can not be repaired by judging whether the two ends of the broken wire are electrified or not easily by the influence of the resistance of a human body, the insulation strength of the human body and the intensity of ambient light; when the universal meter is used for detecting the two ends of the broken wire, no matter whether the broken wire is on the zero wire, on the fire wire or between the zero wire and the fire wire, no matter whether the broken wire is loaded on the line, the universal meter is switched to the voltmeter to be connected with the two ends of the broken wire, the detected voltage is 220V, and whether the two ends of the broken wire can be connected with each other to repair faults cannot be judged.

In this regard, the applicant thought a detection method for judging whether two ends of a broken wire can be connected based on a series voltage division principle, specifically: and (3) connecting the power consumption equipment which can judge the voltage through the working state into two ends of the broken line, if the line is loaded and not shorted, connecting the power consumption equipment with the load on the line in series to divide the voltage, wherein the working state of the power consumption equipment is weaker than the working state under 220V voltage, so that the broken line can be judged to be broken, and the two ends of the broken line can be directly connected to restore the line. Comparing the weight and the volume of the bulb, the loudspeaker and the motor with the fan blades with the difference degree of the working states under different voltages, and finally selecting the bulb which is light in weight, small in volume and large in difference degree of the working states under different voltages and is easy to distinguish by a detector as the power consumption equipment; at present, the applicant takes bulbs with positive and negative electrodes respectively connected with detection lines as detection tools, but in actual use, the bulbs are found to have inconvenient storage, and the bulbs are directly connected to two ends of a broken line through the detection lines, so that the safety is poor.
