Abstract

The invention provides a ring main unit which comprises an incoming cabinet. The incoming cabinet comprises a first incoming cabinet, a second incoming cabinet and a first locking device, wherein the input ends of the first incoming cabinet and the second incoming cabinet are respectively connected with a power supply; the output ends of the first incoming cabinet and the second incoming cabinet are respectively connected with the same load; the first incoming cabinet is provided with a first switch operating mechanism; the first switch operating mechanism enables the first incoming cabinet to have a first switch-on position and a first switch-off position; the first locking device comprises a first transmission mechanism and a first baffle connected with the first transmission mechanism; and when the first switch operating mechanism is rotated to enable the first incoming cabinet to be at the first switch-on position, the first transmission mechanism drives the first baffle to move, so that the first baffle is positioned a first shielding position for shielding an operating space of a second switch operating mechanism. The technical scheme adopted by the invention effectively solves the problem of breakdown of an integral power supply system, which is caused by the fault of the ring chain unit in the prior art, and avoids misoperation.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a ring network cabinet. Background technique [0002] With the development of the national economy and the advancement of science and technology, industrial and mining enterprises, residential quarters, ports and high-rise buildings have begun to use ring network cabinets on a large scale. The structure of the ring network cabinet is simple, the operation is safe and reliable, the maintenance frequency is low, and the operation cost is low. Compared with the traditional switch cabinet, the advantages are very prominent. [0003] However, in the prior art, when the power supply or the system of the ring network cabinet breaks down, the entire power supply system will be paralyzed. Contents of the invention [0004] The present invention aims to provide a ring network cabinet to solve the problem in the prior art that the entire power supply system will be paralyzed when...
