Not only is the city's power supply system composed of a large number of wires, but the transmission of electricity to thousands of households also requires wires as the main construction material. It can be seen that wires have an indispensable position in modern cities.

[0003] The existing wire structure is usually composed of a wire core and a wire sheath. The wire core is usually made of copper, and the wire sheath is also called an insulating sheath.

[0005] At present, after the production of electric wires is completed, it is usually necessary to use manual methods to conduct quality inspection of the wire sheath. During the quality inspection, the workers mainly observe with their naked eyes to see if the wire sheath is damaged. It is often the case that the wire sheath is damaged but the workers fail to detect it, and the detection accuracy is low. Utility Model Content

The multiple partition plates 11 divide the cell body 1 into multiple long strip detection channels 12. Each detection channel 12 is injected with a detection liquid 121 containing metal ions. By immersing the wire connected to the power in the detection liquid 121, and connecting a detection device that uses power to emit light in the detection liquid 121, if the wire sheath is damaged, the current flowing in the detected wire will be guided to the electrical equipment by the detection liquid 121, and the electrical equipment will sound an alarm, so that the detection effect is more accurate, thereby achieving the effect of improving the accuracy of wire sheath detection.

[0029] A specific application of this embodiment is:

[0030] When in use, since the wiring switches 21 at the ends of multiple detection channels 12 are connected in parallel and equipped with switches 211, the number of detection channels 12 can be used according to the number of wires to be detected. When performing the test, the worker first connects the two ends of the detected wire with the adjacent wiring switches 21, and the wires are immersed in the detection liquid 121 except for the connected part. Then, the switch 211 of the detection switch connected to the detected wire is closed, so that the current to the power supply 22 can first pass through the resistor 221 and then flow to the wiring switch 21. The current flows through the wire in the detection liquid 121 and then returns to the power supply 22, forming a closed and flowing circuit. If the wire skin is damaged, the current flows into the detection liquid 121, and the detection liquid 121 immediately transfers the current to the nearest detection bulb 3. The bulb that flows through the current first lights up first, and then the detection bulbs 3 corresponding to the detection channel 12 are all lit, indicating that the wire skin is damaged. In summary, through the above steps, the effect of improving the accuracy of wire skin detection is achieved.
