The invention relates to a secondary air switch anti-misoperation locking device which comprises an air switch having a switch groove and a handle with one end extending out of the switch groove, a lock cylinder comprising a lock cylinder plug having a key hole and a lock cylinder shell arranged outside the lock cylinder plug, two clamping hole sets composed of two clamping holes symmetrically formed in the two side edges of the switch groove, an outer cylinder of which the inner diameter is matched with the outer diameter of the lock cylinder shell and the upper portion sleeves the lock cylinder shell, two elastic buckles provided with clamping feet corresponding to the two clamping holes of the clamping hole sets in a one-to-one mode and symmetrically installed on the lower portion of the outer cylinder, a locking device provided with a locking base of which the upper end is connected with the lower end of the lock cylinder shell, a connecting column of which the upper end is connected with the lower end of the locking base, a supporting block of which the upper end is connected with the lower end of the connecting column, and an anti-rotation assembly arranged between the lock cylinder shell and the outer cylinder. According to the secondary air switch anti-misoperation locking device , the air switch cannot be switched on or switched off by mistake, and the safety is relatively good.
Description
technical field [0001] The invention relates to the technical field of electric power safety, in particular to a secondary circuit breaker anti-misoperation locking device and an anti-misoperation locking method. Background technique [0002] In the daily work of power substation operation and maintenance, after operating the primary equipment of the substation, when the staff needs to cut off the power for maintenance, they often need to cut off the power supply through the existence of the secondary circuit breaker (air switch) to ensure the safety of the maintenance personnel. The structure of the air switch can be obtained from a new type of air switch disclosed in the utility model of the Chinese Patent Application No. 202021402136.2; relatively speaking, the safety measures of the primary equipment are very mature, but for the secondary control exposed on the protective screen The power switch and the secondary air switch of the device power switch do not have a lockin...
