Abstract

The invention relates to a looped network switching device, which comprises a shell and a fuse. A load switch is arranged in the shell, the load switch and a tripping device are connected, the tripping device is arranged between the load switch and the fuse, the tripping device is provided with a tripping device main shaft connected with a press plate, the press plate is connected with the fuse, an opening is arranged on the surface of the shell and is provided with a contact, and a switch main shaft is arranged in the load switch and is provided with a reinforcing rib structure. The looped network switching device disclosed by the invention has the advantages of increasing electric clearance, effectively preventing a creepage situation and reinforcing the torsional strength of the switching main shaft.

Description

technical field [0001] The invention relates to a ring network power supply device, in particular to a ring network switch device. Background technique [0002] Sulfur hexafluoride ring network switchgear, as a new type of high-voltage electrical product, has the advantages of small size, light weight, beautiful appearance, and simple structure. Therefore, it has been recognized by more and more users and has been more and more widely used. . However, the 25kv sulfur hexafluoride products that appear in the market are produced by the direct transformation of 12kv sulfur hexafluoride, and there are some safety problems, such as insufficient electrical clearance, which can generate interphase arcs; the switch spindle breaks during use and so on. Contents of the invention [0003] In order to overcome the above defects, the technical problem to be solved by the present invention is to propose a ring network switchgear with high main shaft strength, accurate positioning and ...
