Abstract

The invention provides an interlocking mechanism which is applied in the technical field of high-voltage switch equipment. A grounding switch (3) is arranged in a switch cabinet, the interlocking mechanism comprises a ground rod (4), one end of the ground rod (4) is connected with the grounding switch (3), the other end of the ground rod (4) is movably connected with a connecting rod (5), the other end of the connecting rod (5) is movably connected with a side plate (1) of the switch cabinet, an interlocking piece (6) is arranged on a rear sealing plate (2) of the switch cabinet, a groove (7) is formed in the interlocking piece (6), and one end, connected with the side plate (1) of the switch cabinet, of the connecting rod (5) is provided with a movable piece (8). According to the interlocking mechanism, the structure is simple, when the grounding switch is switched on, the interlocking for the rear sealing plate of the switch cabinet can be achieved, the rear sealing plate of the switch cabinet is prevented from being opened, and when the grounding switch is switched off, the interlocking for the rear sealing plate of the switch cabinet can be released, so that when operating personnel conduct detection operation to the switch cabinet, the operation can be conducted under a safe environment.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switchgear, and more specifically relates to an interlocking mechanism for interlocking a rear sealing plate of a switchgear of a high-voltage switchgear. Background technique [0002] At present, in the power system, when the high-voltage switchgear is relatively close to the rear wall, the rear door of the switchgear cannot use a hinged door, but only a detachable rear sealing plate structure. With such a structure, no interlocking relationship is established between the rear sealing plate and the grounding switch. Therefore, no matter when the grounding switch is turned on or off, the rear sealing plate of the switchgear can be opened, and the operator operates or repairs the switchgear without knowing it, which is very easy for the operator to enter the live switchgear compartment by mistake. , resulting in major safety accidents. Contents of the invention [0003] The technical probl...
