The utility model has the advantages of simple structure, perfect assembly, light and handy volume, reliable operation, etc.; the utility model is provided with the capability for opening and breaking a load current of 100 A and a load current below 100 A besides the protective capability of short circuit accidents.
Description
Technical field
The utility model relates to the isolating switch with deciliter 100A and following rated load electric current.
Background technology
Outdoor disconnector do not possess deciliter load current ability, can only be applicable to the waypoint in a certain section railroad section of the already present switchgear of only making buffer action on the circuit.At little load loop, have to depend on circuit breaker and on-load switch at present, so cost is higher, maintenance is bigger, and cost-benefit is low.For existing outdoor disconnector, generally be the single-phase outdoor disconnector of installing one by one, installation is cumbersome, adjusting is difficult, extremely inconvenience of operation, and cost performance is lower.
Summary of the invention
Technical problem to be solved in the utility model be to overcome the defective of prior art and provide a kind of simple in structure, complete, the volume of combination is light and handy, the reliable outdoor composite type load-break switch of operation; this switch is had cut-off the ability of 100A and following load current, possess the ability of short circuit accident protection again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: outdoor composite type load-break switch, comprise the load-break switch that has arc-control device, this load-break switch has a frame, the main shaft supporting of drive part is in the frame bearings at both ends, the insulation supporter is fixed on the frame, centering spring is installed between frame and the main shaft, the operator of current-carrying system links to each other with main shaft by connecting lever with auxilliary cutter, manually close, the operator handle of separating brake links to each other with main shaft, it is characterized in that being provided with the fuse switch that links to each other by connecting plate between described two groups of perpendicular insulation supporters, form knockdown load-break switch.
Described arc-control device adopts arc extinguishing board suit fire-retardant, that arc extinction performance is good to form.
Be connected with earth electrode between described frame and the ground wire.
Be connected with installing rack on the described frame, this installing rack is connected on the single shaft tower by auxiliary is installed.
Compared with prior art; the utility model is behind equipped fuse switch on the existing isolating switch; can realize cut-offfing short circuit current; when overload or short circuit; fuse can fall voluntarily to be protected; advantages such as that this product has is simple in structure, the combination is complete, volume is light and handy, operation is reliable had both had the ability of cut-offfing 100A and following load current, possessed the defencive function of short circuit accident again.
Description of drawings
Fig. 1 is the utility model master TV structure schematic diagram.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the vertical view of Fig. 2.
Embodiment
In conjunction with above-mentioned accompanying drawing embodiment the utility model is described in detail again.
Referring to Fig. 1-3, outdoor composite type load-break switch is the outdoor high voltage switchgear of three-phase alternating current 50HZ, and deciliter little load current in the outdoor aerial distrbution network of 10KV electric pressure is applicable to short circuit accident and not crucial place often not to occur.This product is a three-phase mechanical linkage formula, has the ability of cut-offfing 100A and following load current.Simultaneously behind the common 10KV high voltage fuse of device; also possesses defencive function to short circuit current; its mode of operation is pure manual operation; in normal operation promptly; after load-break switch is opened; available link rod (insulated hook rod) is operated the input of fuse switch and is withdrawed from, thereby has guaranteed that fuse switch is always the operation of nothing electricity.
This switch comprises frame 1, and it adopts steel plate to bend postwelding reconditioning moulding, and the surface sprays outdoor epoxy resin processing again after zinc-plated, guarantee outdoor not corrosion in 10 years.Be connected with installing rack 12 on the frame, installing rack is connected on the single shaft tower by auxiliary 9 is installed.Be connected with earth electrode 10 between frame and the ground wire, in case frame is just in case when charged, can guarantee the safety of the person, equipment.
The main shaft 2 of drive part is bearing in the needle bearing at frame 1 two ends, and is lightly flexible during rotation.Insulation supporter 4 is fixed on the frame, is the silicon rubber insulator of the full operating mode of large distance.Arc-control device 7 is installed on the insulation supporter, adopts the good arc extinguishing board suit of fire-retardant arc extinction performance to form, and arc extinguishing board is arranged on the quiet tool rest, and its strutting piece is stainless steel and makes, and the diffusion with restriction separating brake electric arc reaches the arc extinguishing purpose.
Centering spring 3 is installed between frame and the main shaft, can be branch, closing a floodgate gathers way.
The operator 5 of current-carrying system links to each other with main shaft 2 by connecting lever with auxilliary cutter 6, and operator is that fine copper fine finishining forms, and surperficial bright nickel plating electrification is handled.Auxilliary cutter is made by stainless steel substrates and is furnished with the spring accelerator, can improve auxilliary cutter separating rate when separating brake rapidly.
Between two groups of perpendicular insulation supporters 4, be provided with the fuse switch 8 that links to each other by connecting plate, its upper and lower two and middle fuse tube and RW7-10 fuse switch can be general, fuse switch is buied by commercially available, it reliably links together by insulation column, pole, frame, following stationary contact tool rest, when overload or short circuit, fuse falls voluntarily.
Manually close, the operator of separating brake links to each other 11 with main shaft 2, for operating personnel with insulating rod manually close, sub-switching operation.
Dynamic structure of the present utility model is:
" closing " of spurring downwards on the operating grip with the insulation hook stick during closing operation encircled, make the spindle axis counterclockwise rotation of drive system, when forwarding certain angle to, be fixed on the connecting lever compression centering spring on the main shaft, quicken driving main shaft, connecting lever, make operator finish feed motion rapidly.With " branchs " ring on the insulation hook stick pull operation handgrip, make main shaft clockwise during sub-switching operation, when forwarding certain angle to, spring excessively in, quicken driving main shaft, connecting lever, operator, auxilliary cutter motion, finish separating brake and move.During separating brake, when the moment that operator separates, auxilliary cutter does not break away from as yet fully, at this moment by the spring accelerator on the auxilliary cutter, accelerate the separating rate of auxilliary cutter suddenly, reduce the generation of separating brake electric arc, limit the diffusion of separating brake electric arc simultaneously by the auxilliary cutter of arc-control device, to reach the purpose of arc extinguishing.
Owing to installed supporting suitable 10KV transformation fuse in the fuse switch, when by short circuit current, the quick-break of pipe inner high voltage fuse, fuse tube fall automatically, reach the automatic protection purpose to short circuit current.
