Technical Field

[0001] The invention relates to the field of line leakage detection, in particular to a high-voltage transmission line leakage detection device. Background Art

[0002] The electricity generated by the power plant is not only for use by people nearby, but also needs to be transmitted to faraway places to meet more needs. This electricity cannot be transmitted directly through ordinary wires, but must be transmitted using high-voltage transmission lines. Generally, the transmission voltage below 220 kV is called high voltage transmission, the transmission voltage between 330 and 765 kV is called ultra-high voltage transmission, and the transmission voltage above 1000 kV is called extra-high voltage transmission.

[0003] After long-term use, high-voltage transmission lines will experience leakage. Maintenance personnel often need to perform leakage detection on high-voltage transmission lines. Most existing detection devices can only detect single transmission lines one by one. This detection method is inefficient, and during detection, the detection probe directly contacts the high-voltage wires, which often directly breaks down the detector due to excessive current, bringing certain dangers.

At this time, the detection probe touches the closed copper pipe, which can not only quickly detect whether leakage occurs, but also ensure the safety of the equipment and prevent the dangers caused by improper operation.
