Occupation space is little, and insulating reliability is good to addding one deck shield layer outside the insulating layer, further having improved insulating nature and fail safe nature, simple structure, with low costs and electric discharge phenomena has been eliminated to such structure, has improved reliability and life.
Description
Technical field
The utility model belongs to high-voltage switch gear electrical equipment, relates to a kind of solid insulation ring main unit shielding plug-in fuse.
Background technology
At present, what China's urban electricity supply network mainly adopted is ring network power supply pattern, and ring network power supply pattern can provide power supply reliability to power consumer, reduces electric power accident impact. Traditional ring main unit mainly adopts air insulation and SF6 gas-insulated, along with the development of national economy, power consumer is also more and more higher to the requirement of power supply quality and environmental issue, and a little less than the anti-pollution ability of air insulation ring main unit, large problem affected by environment highlights day by day; Although and SF6 gas has good arc extinguishing and insulating properties, can make ring main unit realize miniaturization, SF6 gas is one of internationally recognized six kinds of greenhouse gases, be that balance of plant requirement restriction is used or no gas. Therefore in the last few years, many research institutions and manufacturing firm, just at developmental research solid insulation ring main unit, adopted epoxy resin and silicon rubber as insulating materials, and element insulating layer outer surface applies ground shield, makes the volume miniaturization more of ring main unit.
The mounting means with fuse in the combined electrical apparatus cabinet of fuse of using as tranformer protection; some employing fuse unit mounting means; find according to practical operating experiences, this structure is particularly easy to Discharge Phenomena in fuse unit end, finally causes insulation breakdown. The combination of some employing gas-insulateds and insulating cylinder, this structural reliability is higher, but complex structure, cost is higher.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of solid insulation ring main unit shielding plug-in fuse simple in structure, that cost is low, reliability is high and security is good is provided.
Shielding plug-in fuse for solid insulation ring main unit of the present utility model, comprises fuse, and described fuse comprises main paragraph and is positioned at the plug at main paragraph two ends; On the main paragraph outer circumference surface of described fuse, be coated with a layer insulating, on the outer circumference surface of described insulating barrier, be coated with the ground shield that one deck is made by conductive material; It also comprises and is arranged on inserts on plug, conduction, and described inserts has for link that in solid insulation ring main unit, other electrical equipment is connected with plug with plug the slotting chamber coordinating towards inner side; The outer surface of described inserts is also coated with a layer insulating and is coated on the ground shield on insulating barrier; The action output mechanism of a thimble driving mechanism is installed on one of them inserts, and described action output mechanism can drive the on-load switch action of solid insulation ring main unit in the time that the electric current that flows through fuse is excessive.
The two ends of the insulating barrier on described main paragraph are the male cone (strobilus masculinus) that diameter diminishes gradually laterally from inner side; Insulating barrier outside described inserts extends to form docking container cavity to the interior side direction of inserts, and the side face of described docking container cavity is the inner conical surface matching with male cone (strobilus masculinus).
Insulating barrier outside described inserts forms connection chamber, and the outer end of described link extend in described connection chamber.
The utility model has the advantage of: first: by carrying out the insulation of equipment room at fuse outer cladding insulating barrier, take up room little, insulating reliability is good, and set up one deck ground shield outward at insulating barrier, insulating properties and security reliability are further improved, simple in structure, cost is low, and such structure eliminated electric discharge phenomena, improved reliability and service life. Second: the docking between inner conical surface and male cone (strobilus masculinus) coordinates closely, improve fuse and the inserts insulating properties between connecting portion and miscellaneous equipment. The the 3rd: the structure of connection chamber makes fuse and the insulating properties of miscellaneous equipment between connecting portion and miscellaneous equipment.

Detailed description of the invention
As shown in the figure: shielding plug-in fuse for a kind of solid insulation ring main unit, comprise fuse 01, described fuse 01 comprises main paragraph 011 and is positioned at the plug 012 at main paragraph 011 two ends; On main paragraph 011 outer circumference surface of described fuse 01, be coated with a layer insulating 02, on the outer circumference surface of described insulating barrier 02, be coated with the ground shield 03 that one deck is made by conductive material; Between described main paragraph 011 and insulating barrier 02, be also provided with the buffer transition layer 04 that one deck is made by elastomeric material. Described buffer transition layer can adopt silicon rubber, prevents that fuse from producing stroke layer or cracking because rising-heat contracting-cold coefficient is different from insulating barrier.
It also comprises and is arranged on inserts 05 on plug 012, conduction, and described inserts 05 has for link 052 that in solid insulation ring main unit, other electrical equipment is connected with plug with plug 012 the slotting chamber 051 coordinating towards inner side; The outer surface of described inserts 05 is also coated with a layer insulating 02 and is coated on the ground shield 03 on insulating barrier 02; The action output mechanism 06 of a thimble driving mechanism is installed on one of them inserts 05.
The two ends of the insulating barrier 02 on described main paragraph 011 are the male cone (strobilus masculinus) 021 that diameter diminishes gradually laterally from inner side; Insulating barrier 02 outside described inserts 05 extends to form docking container cavity 07 to the interior side direction of inserts 05, and the side face of described docking container cavity 07 is the inner conical surface 022 matching with male cone (strobilus masculinus) 021. Extend to form connection chamber 08 without the insulating barrier 02 outside the inserts 05 of driving mechanism 06 to the lateral direction of inserts 05, have the insulating barrier 02 outside the inserts 05 of driving mechanism to form a connection chamber 08 at circumferencial direction. The outer end of described link 052 extend in described connection chamber 08.
