Abstract

The invention discloses a connector. The connector comprises a semi-arc first connecting main body and a semi-arc second connecting main body, wherein the first connecting main body and the second connecting main body are connected through a buckle assembly; the first connecting main body and the second connecting main body are each provided with an outer shell, an inner shell and a semicircular inner hole. The semicircular inner hole is clamped with an insulation shielding layer of the cable, and the inner shell is sleeved on the outer surface of the cable; the first connection main body is also provided with a through pipe hole, and the pipe hole is arranged between the insulation shielding layer and the aluminum sheath layer of the cable. The invention further discloses a device for repairing poor electric contact in the high-voltage cable. The device comprises a pressurizing gas cylinder, a repairing liquid storage bottle, repairing liquid, a first liquid guide pipe, a residual liquid collector, a vacuum pump and the connector. According to the invention, the electric contact performance between the insulation shielding layer and the aluminum sheath of the cable can be effectively improved, and the cable failure rate caused by poor contact between the insulation shielding layer and the aluminum sheath of the cable is reduced, so the operation reliability of the defective cable is greatly improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable safety, in particular to a connector and a device for repairing poor electrical contact inside a high-voltage cable. Background technique [0002] With the acceleration of urbanization and the rapid increase of urban electricity consumption, the demand for high-voltage cables has grown rapidly. Compared with other cables, cross-linked polyethylene (XLPE) insulated cables have outstanding advantages such as excellent electrical and mechanical properties, good heat resistance, convenient installation and maintenance, and do not require oil and gas supply equipment, so they are more widely used . However, in recent years, in Beijing, Shanghai, Guangzhou, Nanjing, Macau and Australia, many high-voltage XLPE cable body faults caused by the ablation of the cable buffer layer have occurred, which has attracted great attention from cable industry experts and scholars. [0003] The buffer laye...
