Abstract

The invention discloses a connector, which comprises: a semicircular arc-shaped first connecting body and a second connecting body; the first connecting body and the second connecting body are connected by a buckle assembly; All are equipped with an outer shell, an inner shell and a semicircular inner hole; the semicircular inner hole is clamped to the insulation shielding layer of the cable, and the inner shell is set on the outer surface of the cable; the first connecting body is also provided with a through-tube hole, and the tube hole is set Between the insulation shielding layer of the cable and the aluminum sheath layer. The invention also discloses a device for repairing poor electrical contact inside a high-voltage cable, including: a pressurized gas cylinder, a repair liquid storage bottle, a repair liquid, a first catheter, a residual liquid collector, a vacuum pump and the above-mentioned connector. The invention can effectively improve the electrical contact performance between the insulating shielding layer of the cable and the aluminum sheath, reduce the cable failure rate caused by poor contact between the cable insulating shielding layer and the aluminum sheath, and thus greatly improve the operation of such defective cables reliability.

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...
