Abstract

The invention discloses an anti-locking mechanism of a switch apparatus. The anti-locking mechanism (11) is arranged at one end of a ground switch operation shaft (5) positioned on a panel (3); and a clutch structure is adopted, namely, the body (1) of the switch apparatus is provided with a trip pin (10), a clutch sleeve (9) is arranged on the end part of the ground switch operation shaft (5), atransverse groove is formed on the clutch sleeve (9), when the panel (3) is opened, the strip pin (10) is clamped into the transverse groove, and when the panel (3) is closed, the strip pin (10) is separated from the transverse groove. Compared with the prior art, the anti-locking mechanism has the remarkable characteristics of simple working principle and structure, simple technique for manufacturing parts of the mechanism, high anti-locking reliability, no maintenance and stable working performance.

Description

technical field [0001] The invention belongs to the technical field of electric power distribution equipment, and relates to a "five-proof" interlocking technology of a metal armored removable switchgear, more specifically, the invention relates to an anti-locking mechanism of a switchgear. Background technique [0002] At present, the 10kV armored metal removable switchgear (hereinafter referred to as: switchgear) produced by various domestic power supply equipment manufacturers, according to the requirements of the switchgear manufacturing standard, meets the "five-proof" interlocking functions of the switchgear and ensures When the switchgear and operators are safe, the "five-proof" interlocking of the switchgear is further improved. [0003] However, the effect of the prior art is unsatisfactory, and cannot meet the security requirements in specific situations. Below in conjunction with accompanying drawing of this specification, the problem that prior art exists is ana...
