Abstract

The invention relates to a ring main unit and a replacement method of the ring main unit. The ring main unit comprises a cabinet body, an access cable, a shielding type front connector and a connectorassembly. One end of the access cable is connected with a power supply, the other end of the access cable is detachably connected with the joint assembly, one end of the joint assembly away from theaccess cable is detachably connected with the shielding type front joint, and one end of the shielding type front joint away from the joint assembly is connected with the butting sleeve on the cabinetbody. According to the scheme provided by the invention, the connecting wire is installed on the shielding type front joint on the new cabinet body in advance, so that when the ring main unit needs to be replaced, only the auxiliary cable needs to be dismounted from the quick plug-pull type terminal, and then the connecting wire on the new cabinet body is inserted into the quick plug-pull type terminal; the whole operation not only shortens the power failure time, but also reduces the operation intensity and obviously improves the working efficiency.
