Description
Technical field
The utility model belongs to electric power system service technique field, is specifically related to the special locking fixture of a kind of central switch cabinet isolation baffle plate.
Background technology
In recent years, the application of central switch cabinet in system is more and more, has become the substitute products of middle-low voltage switch cabinet technological transformation, but due to this switch cubicle self design and reasons in structure, in the time of upkeep operation, has major safety risks.In the time of central switch cabinet repair and maintenance, after circuit breaker cart pulls out from middle-placed switch cabinet, still charged owing to being positioned at main bus bar after central switch cabinet, like this, in the time of the each parts Inspection and maintenance in cabinet, be easy to touch charged position, thereby jeopardize operating personnel's personal safety and device security.
Specifically, in the time of the sealing of upper and lower isolation baffle plate, shelter from respectively and be positioned at upper and lower two-layer 6 charged fixed contacts after baffle plate.This situation provides reliable safety measure for upkeep operation personnel, and operating personnel can not touch charged fixed contact.But in the time that the hoisting mechanism of upper and lower isolation baffle plate is carried out to repair and maintenance, due to upkeep operation personnel's inertial thinking, after Inspection and maintenance is complete, lifting for controlling upper and lower isolation baffle plate with hand of can can't help risen, the pole of decline.In the time depressing upper rack posts, lower isolation baffle plate can move down, and automatically opens 3 fixed contact boxes that are positioned at lower floor, and 3 charged fixed contacts are spilt cruelly; In the time lifting lower fulcrum bar, upper isolation baffle plate can move up, and automatically opens 3 fixed contact boxes that are positioned at upper strata, makes equally 3 charged fixed contacts cruelly spill.Therefore no matter press down pole or lift pole, both of these case all can cause repair and maintenance personnel to get an electric shock, thereby jeopardizes the person and device security.
Utility model content
The purpose of this utility model is to provide a kind of central switch cabinet simple in structure, easy to process, with low cost, easy to use isolation baffle plate special locking fixture.
The special locking fixture of a kind of central switch cabinet isolation baffle plate, comprise upper bracket and lower carriage, described upper bracket is made up of chuck and locating part, described chuck and locating part are welded to connect, described chuck is made up of screw rod and securing rod, described screw rod one side arranges groove, described securing rod is arranged in groove by spring, described locating part is welded to form by three block plates, described locating part entirety is " F " type, the structure of described lower carriage and upper bracket is identical, described upper bracket is relative with lower carriage puts upside down setting, the locating part of described upper bracket and lower carriage is cross-linked and is integrated by gag lever post.
Between described upper bracket and the locating part of lower carriage, hard spring is set.
Described chuck is bolt arrangement.
Described lower carriage comprises gag lever post and chuck, and described gag lever post one end and described chuck weld together.
The beneficial effects of the utility model are: between the control pole of the utility model by two the isolation baffle plates up and down at central switch cabinet, locking fixture is set, by the displacement restriction of upper and lower two control supports in a limited scope, realize by jig, between lower two poles, position is relatively fixing, upper rack posts presses not go down like this, lower fulcrum bar can not lifted, on, on lower isolation baffle plate also just can not carry out, lower movement, maintain the position that can shelter from fixed contact box, thereby realize the effective locking to central switch cabinet isolation baffle plate, personal safety and device security in repair and maintenance personnel operation process are guaranteed.For realizing this function, described locking fixture is connected as one by gag lever post is interlaced by upper and lower two supports, and wherein, the two ends up and down of locking fixture arrange respectively a chuck and are used for the utility model to be fixed on upper lower fulcrum bar.Described chuck is made up of screw rod and securing rod, described screw rod sidewall arranges groove, described securing rod is arranged in groove by spring, this structure in use, first securing rod is pulled out in the groove of screw rod sidewall, again by screw rod through pole, finally unclamp securing rod and it returned back in groove can realize quickly and easily both being fixedly connected with.The utility model is realized the restriction of displacement by locating part, described locating part is welded to form by three block plates, described locating part entirety is " F " type, the locating part of described upper bracket and lower carriage is cross-linked and is integrated by gag lever post, this structure can be by the offset qualification between upper lower carriage between two steel plates that parallel, and effectively prevent that lower carriage from because touch by mistake, larger movement occurring.Further, in order to make structure of the present utility model more simple and practical, cheap for manufacturing cost, described chuck can be bolt arrangement, is fixed by nut, and the locating part only arranging on gag lever post and upper bracket on described lower carriage links together.
