Description
Technical field
The present invention relates to a kind of intensive insulation bus ducts.
Background technology
Multiple busbars are provided in bus duct, to transmit electric energy, have the function of to collect and distribute electric power.By it,
The electrical energy transportation that generator, transformer or rectifier are exported gives each user or other electric substations.
Bus duct is in power Transmission trunk project project more and more instead of electric wire.In external prosperity
The Hong Kong in country and China, Macao etc. have popularized.In the Guangzhou Guangdong in China, all 12 layers or more Building Power Distribution room outlets are drawn
To 90% bus duct used above of backbone of floor；630KVA transformers to power distribution cabinet will use bus duct.Large- and-medium size cities
Gongjian's project, hotel, using bus duct, also universalness, bus duct are the indoor following power Transmissions of rated voltage 1000V to office building
The optimal selection of main line.
Since bus duct is in electric energy transmission process, high current, high voltage are carry, therefore, bus duct product is to insulation
Performance, fire resistance have high requirement, but existing bus duct is still hard to meet fire resistance requirement.
Invention content
The purpose of the present invention is to provide a kind of insulation, the intensive insulation bus ducts of excellent fire retarding performance.
To achieve the above object, the present invention provides a kind of intensive insulation bus duct, including busbar protecting crust and is set to
Busbar unit in the busbar protecting crust.Busbar unit includes multiple busbars.Busbar includes busbar conductor leads with the busbar is coated
The insulating layer of body.Multiple busbar side by side parallel set to form an entirety.It is formed with and fills out between busbar protecting crust and busbar unit
Slot is filled, ceramic slurry is injected in filling slot, the ceramic slurry is at least mixed by hydrate calcium sulfate or calcium sulfate with water
It is formed, fire resisting fire division wall is formed by curing after ceramic slurry injection filling slot.
As described above, intensive insulation bus duct of the present invention is during fabrication, ceramic slurry is filled in filling using injection mode
It is simple for process in slot.In addition, during ceramic slurry and fire resisting fire division wall is formed, hydrate calcium sulfate or calcium sulfate with
Water, which combines to occur to chemically react, forms polyhydrate calcium sulfate so that water as much as possible, resistance to fire screen are loaded in fire resisting fire division wall
Wall with flues, which is met when fire is heated to a certain extent, can release water vapour as much as possible, and absorb heat during discharging water vapour,
This endothermic process can play cooling effect in itself, and water vapour volatilization can continuously take away heat, make busbar
The temperature of slot reduces, this can improve the fire resistance of bus duct, and fire resisting fire division wall can play fire resisting and isolation fire simultaneously
The effect in source.
Description of the drawings
Fig. 1 is the cross section structure schematic diagram of intensive insulation bus duct of the present invention.
In figure：Busbar protecting crust 10, metallic plate 11, bolt 12, busbar 20, busbar conductor 21, Ceramic silicon rubber layer 22,
Ceramic silicon rubber fire resisting composite band 23, filling slot 30.
Specific embodiment
For the technology contents that the present invention will be described in detail, modular construction, the objects and the effects, given in detail below in conjunction with attached drawing
Explanation.
Referring to Fig. 1, intensive insulation bus duct of the present invention is substantially in a rectangular parallelepiped shape, including busbar protecting crust 10 and setting
Busbar unit in the busbar protecting crust 10.
Busbar protecting crust 10 is the guard shield of intensive insulation bus duct, generally metal shell, such as steel or irony
Housing has the function of protection bus duct internal part, and in the present embodiment, busbar protecting crust 10 is enclosed by four pieces of metallic plates 11
Into two adjacent metal sheets are fixed together by bolt 12, naturally it is also possible to are screwed.
Busbar unit includes multiple busbars 20.Busbar 20 includes busbar conductor 21 and coats the insulation of the busbar conductor 21
Layer.Insulating layer mainly plays busbar conductor 21 insulated fireproof, and in the present embodiment, busbar conductor 21 is coated with ceramic SiClx
Rubber layer 22, Ceramic silicon rubber layer 22 are surrounded with Ceramic silicon rubber fire resisting composite band 23 outside.Ceramics outside busbar conductor 21
SiClx rubber layer 22 and wrapped Ceramic silicon rubber fire resisting composite band 23 form the insulating layer.Ceramic silicon rubber fire resisting is answered
Crossed belt 23 can play the role of flame-retardant, and flame-retardant is had excellent performance, and remaining to ablation even more than fire endurance burning forms
Hard protective shell, protective shell can prevent flame from further extending to busbar conductor 21, so as to protect positioned at ceramic silicon rubber
Busbar conductor 21 in glue fire resisting composite band is without damage, it is ensured that the normal usage function of busbar 20 improves the safety of product
Property.
Multiple 20 side by side parallel of busbar sets to form an entirety, as busbar unit.Busbar protecting crust 10 and the mother
Filling slot 30 is formed between row's unit, ceramic slurry is injected in filling slot 30, inlet can be opened up on busbar protecting crust 10
（Do not show in figure）To inject ceramic slurry.At least shape is mixed with water by hydrate calcium sulfate or calcium sulfate in the ceramic slurry
Into ceramic slurry is formed by curing fire resisting fire division wall after injecting filling slot.Hydrate calcium sulfate or calcium sulfate are mixed with water can be with
Other substances are added in as needed, but on condition that still slurry can be formed.
Preferably, the hydrate calcium sulfate is less than the weight of water by weight, this can make to be loaded in fire resisting fire division wall to the greatest extent
Water more than possible.
In order to further improve its fire resisting effect, the inner and/or outer fireproof coating that is equipped with of busbar protecting crust forms fireproof coating
Layer（Do not show in figure）.
In conclusion intensive insulation bus duct of the present invention is during fabrication, ceramic slurry is filled in filling using injection mode
It is simple for process in slot.In addition, during ceramic slurry and fire resisting fire division wall is formed, hydrate calcium sulfate or calcium sulfate with
Water, which combines to occur to chemically react, forms polyhydrate calcium sulfate, and water also occurs that physical reactions i.e. water is attached to during water abundance
Polyhydrate calcium sulfate surface so that water as much as possible is loaded in fire resisting fire division wall, fire resisting fire division wall is met fire and is heated to centainly
Water vapour as much as possible can be released during degree, and is absorbed heat during discharging water vapour, this endothermic process in itself can
Cooling effect is enough played, and water vapour volatilization can continuously take away heat, make the temperature of bus duct reduce, this can be carried
The fire resistance of high bus duct, and fire resisting fire division wall can play the role of fire resisting and isolation burning things which may cause a fire disaster simultaneously.
The invention is not limited in above-mentioned specific embodiment, those skilled in the art can also make a variety of accordingly
Variation, such as filling slot can be made improvements, housing will be added again between busbar protecting crust and the busbar unit, which makes to fill out
Slot is filled to be divided into two, ceramic glue can inject one of those or two, but it is any with it is of the invention be equal or similar variation all
It should cover within the scope of the claims.
