Description
Technical Field
The utility model relates to an keep apart rail technical field, especially relate to a special isolation rail of 110kV HGIS overhaul of the equipments.
Background
HGIS equipment is because structural design, its bus and the drainage wire of being connected with the switch all expose outside, so when carrying out the maintenance operation that has a power failure, its bus side switch sleeve pipe drainage wire is electrified position more than and, the power failure work such as routine maintenance, defect treatment, circuit transformation at this type of equipment interval every year accounts for more, and the personnel frequency of participating in the operation improves relatively, and when personnel carried out the maintenance operation to the isolation switch body in the interval, the safe distance that keeps with bus side switch sleeve pipe drainage wire need be paid attention to.
At present, two ways of warning belts and floor type fences are generally adopted aiming at a common security arrangement method in transformer maintenance operation. Wherein: the self bandwidth of the warning belt is 5-8cm, the installation mode is realized by binding on an equipment framework, and the limit that hard isolation cannot be realized, fixing is difficult, the warning belt is influenced by the position shape of the framework and the like exists; the floor type fence has the fixed height of 1.5m (unadjustable), is fixed on the ground in an installation mode, and has the limitations that the floor type fence is easy to blow down by strong wind, is influenced by topographic factors and the like.
Through the practice of an overhaul field, the traditional safety measure arrangement mode and way are inconsistent with the safety requirements of personnel equipment for field operation at present, the problem requirements of various overhaul operation field applications are not met, and the problem is found to be particularly prominent in the process that an operator carries out overhaul work aiming at facilities close to a charged part on a 110kV HGIS equipment interval framework through field investigation. Because of the structural self design restriction of traditional safety measure, can't satisfy 110kV HGIS equipment interval framework top maintenance operation personnel's safety demand.
Disclosure of Invention
To the problem that above-mentioned prior art exists, the utility model provides a special isolation rail of 110kV HGIS overhaul of the equipments, its characterized in that: one side of two upright posts (1) is oppositely provided with a groove (14), two end parts of an isolation net component (3) are fixed in the grooves (14) of the two upright posts (1) through fixing pins A (2), the lap joint part of the isolation net component (3) is connected with a fixing pin B (4), the lower end of the upright post (1) is connected with a connecting pipe (13) at the upper part of a fixed clamp body (5) through a butterfly bolt (6), the connecting pipe (13) is provided with a screw hole (12), the fixed clamp body (5) is L-shaped, the lower end is provided with a fixed duckbill (10), a bulge at one side is vertically provided with a long hole (15), the upper part of the long hole (15) is provided with two blocking pieces (7), a movable clamp body (9) is L-shaped, the upper part is provided with a thread, the lower part is provided with a movable duckbill (11), the movable clamp body (9) passes through the long hole, the movable clamp body (9) is in threaded connection with an adjusting bolt (8), the adjusting bolt (8) is in a ring shape, and the outer circle of the adjusting bolt is provided with a knurl. The isolation net parts (3) are made of hard glass fiber reinforced plastic materials, and the isolation net parts (3) are movably connected with each other and form a plurality of rhombuses. The fixing clamp body (5), the connecting pipe (13) and the fixing duckbill (10) are integrated. The movable clamp body (9) and the movable duckbill (11) are integrated.
The utility model discloses a use method: the adjustable combined plug-in special fence is developed by combining the structural characteristics of a 110kV HGIS equipment framework, when the adjustable combined plug-in special fence is used, the movable clamp body is adjusted by the adjusting bolt to move up and down to control the distance between the movable duckbill and the fixed duckbill to be clamped on the equipment framework, the separation net is pulled open through the stand columns, and then the two stand columns are respectively inserted into the connecting pipes and are respectively fixed by the butterfly bolts.
The beneficial effects of the utility model reside in that: adopt insulating hard material, when effective isolation, also can ensure personal, equipment safety, after the isolation net borrows for the reference rhombus four-bar linkage receives external force, realize that the design principle of deformation designs out telescopic rack main part, convenient storage and installation, the folder adopts the activity fixed knot to construct, can dismantle the installation in a flexible way. The isolation net components are connected into a plurality of rhombuses to form the isolation net, the color of the isolation net is red and white, the color is more striking, and therefore the protection effect of the fence is more obvious, and the visual warning effect is achieved.
