Abstract
The utility model provides a prevent insulator arrangement of arc light short circuit, includes the cross arm and installs the fuse on the cross arm that the insulator arrangement still including being located the insulation board between the adjacent looks fuse, made by insulating material by the insulation board to fixed mounting is on the cross arm. The utility model has the advantages of this insulator arrangement through house ornamentation between adjacent looks fuse by the insulation board that insulating material made, reach the mesh that prevents arc light short circuit phenomenon and form to the reduction power supply line fault rate, improves line power supply's reliability, the insulation board passes through fixed connection part firmly to be fixed on the cross arm, has adapted to the needs that open -air environment used, this insulator arrangement has simple structure, convenient to use, low cost's advantage, is suitable for 6KV, 10KV power supply line.
Description
Technical field
The utility model is related to circuit isolation protection technique field, more particularly, to a kind of insulation for preventing arc short-circuit
Device.
Background technology
Arc short-circuit refers to the gas discharge phenomenon that arcuation white light is presented and high temperature is produced, either in low density gas, gold
In category steam or air, when power is larger, sufficiently large electric current can be provided so that gas breakdown, you can form arc light and put
Electrical phenomena, sends strong radiance and with high temperature in electric discharge.Fuse switch is that fuse protecting device is commonly used in supply line,
Fuse is in normal work, and fuse is in the close position, and when system jam, fault current makes fuse fuse rapidly,
And electric arc is formed with the fuse that fuses.But when arc-control device fail or production spark beyond arc-control device arc extinguishing energy
Power, the spark that adjacent two-phase fuse is produced will be touched together, now may result in different phases（Polarity）Circuit occur it is short
Road phenomenon, continues electric arc and then forms arc short-circuit phenomenon, and fire will be caused when serious.
The content of the invention
The purpose of this utility model is to provide a kind of seal for preventing arc short-circuit, and this kind of device is by adjacent
The mode of house ornamentation insulation board between phase fuse, be with the technical scheme for preventing the generation of arc short-circuit phenomenon, use：One kind is anti-
The only seal of arc short-circuit, including cross-arm and the fuse on the cross-arm, it is characterised in that：The insulation dress
The insulation board for also including being located between adjacent phase fuse is put, the insulation board is made up of insulating materials, and be fixedly mounted on described
On cross-arm.
Technical characteristic of the present utility model also has：The insulating materials is bakelite.
Technical characteristic of the present utility model also has：The bottom of the insulation board is described to be fixedly connected with portion is fixedly connected
Portion includes connecting plate, and bolt hole is provided with the connecting plate.
Technical characteristic of the present utility model also has：The connecting plate is two panels, and two panels connecting plate is mutually perpendicular to, two panels connection
Plate is bolted on two surfaces of cross-arm respectively.
Technical characteristic of the present utility model also has：The size of the insulation board is not less than 60 × 40cm, and the fuse is to fall
The formula that falls fuse.
The beneficial effects of the utility model are：This seal is by the house ornamentation between adjacent phase fuse by insulating materials
The insulation board being made, reaches the purpose for preventing arc short-circuit phenomenon from being formed, and to reduce supply line's fault rate, improves line powering
Reliability；Insulation board is fixedly secured on cross-arm by the portion of being fixedly connected, the need for having adapted to wild environment use；This insulation
Device has simple structure, advantage easy to use, with low cost, is suitable to 6KV, 10KV supply line.
Brief description of the drawings
Accompanying drawing 1 is the utility model front view, and accompanying drawing 2 is panel structure schematic diagram, and accompanying drawing 3 is the right view of accompanying drawing 2,
Wherein 1 is cross-arm, and 2 is fuse, and 3 is insulation board, and 31 is connecting plate, and 32 is bolt hole.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses one kind
The seal of arc short-circuit is prevented, the device is mainly reached by the insulation board 3 being arranged between adjacent phase fuse switch
Prevent the purpose of arc short-circuit.Specially：Fuse 2 including cross-arm 1 and on cross-arm 1, the seal also includes
Insulation board 3 between adjacent phase fuse, insulation board 3 is made up of insulating materials, and is fixedly mounted on cross-arm 1.
Preferably, the insulating materials that insulation board 3 is selected is bakelite.Bakelite light weight, and corrosion resistance and anti-ageing
Change new property good, it is ensured that the service life requirement of seal.
In order to realize the purpose being connected in the present embodiment, the bottom of this insulation board 3 has the portion that is fixedly connected, fixed to connect
Socket part includes connecting plate 31, is provided with bolt hole on connecting plate 31,32, insulation board is fixed on cross-arm 1 by bolt when fixed.
In view of the Common Shape of cross-arm 1, connecting plate 31 is set to two panels, two panels connecting plate is mutually perpendicular to, two panels connection
Plate is bolted on two surfaces of cross-arm 1 respectively, and this kind of connected mode ensure that what connecting plate was connected on cross-arm
Fastness.
In view of the size of fuse switch, by being designed and sized to not less than 60 × 40cm, so guarantee for insulation board 3
Insulation board is slightly larger than fuse switch, and the purpose of arc short-circuit is prevented more preferably to reach.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
Change, remodeling, addition or replacement that the those of ordinary skill in art field is made in essential scope of the present utility model, also belong to
In protection domain of the present utility model.
