Abstract
The utility model discloses a kind of intensive insulation bus slot, comprises busbar protecting crust and is arranged at the busbar unit in this busbar protecting crust.Busbar unit comprises multiple busbar.Busbar comprises the insulating barrier of busbar conductor and this busbar conductor coated.Multiple busbar side by side parallel arranges formation entirety.Be formed with filling slot between busbar protecting crust and busbar unit, in filling slot, be injected with ceramic slurry.During fabrication, ceramic slurry adopts injection mode to be filled in filling slot to the intensive insulation bus slot of the utility model, and ceramic slurry is injected filling slot Post RDBMS and formed fire-resistant fire division wall, and technique is simple.In addition, fire-resistant fire division wall forms fire division wall between burning things which may cause a fire disaster and busbar unit, and this can improve the fire resistance of bus duct, improves intensive insulation bus slot continued power ability in a fire, extends the intensive insulation bus slot continued power time in a fire.
Description
Technical field
The utility model relates to a kind of intensive insulation bus slot.
Background technology
Be provided with multiple busbar in bus duct, in order to electric energy transmitting, there is the function of collecting and distributing electric power.By it, give each user or other electric substations the power delivery of generator, transformer or rectifier output.
Bus duct instead of electric wire more and more in electric power conveying route engineering project.Developed country abroad, and Hong Kong of China, Macao etc. are universal.In the Guangzhou Guangdong of China, all more than 12 layers Building Power Distribution room outlets, the backbone more than 90% namely causing floor uses bus duct; 630KVA transformer will use bus duct to power distribution cabinet.Gongjian's project of large-and-medium size cities, hotel, office building uses bus duct also universalness, and bus duct is the optimal selection of the following electric power conveying route of indoor rated voltage 1000V.
Because bus duct is in delivery of electrical energy process, carry big current, high voltage, therefore, bus duct product has high requirement to insulation property, fire resistance, but existing bus duct is still difficult to meet fire resistance requirement.
Utility model content
The purpose of this utility model is the intensive insulation bus slot providing a kind of insulation, excellent fire retarding performance.
For achieving the above object, the utility model provides a kind of intensive insulation bus slot, comprises busbar protecting crust and is arranged at the busbar unit in this busbar protecting crust.Busbar unit comprises multiple busbar.Busbar comprises the insulating barrier of busbar conductor and this busbar conductor coated.Multiple busbar side by side parallel arranges formation entirety.Be formed with filling slot between busbar protecting crust and busbar unit, be injected with ceramic slurry in filling slot, ceramic slurry is injected filling slot Post RDBMS and is formed fire-resistant fire division wall.
As mentioned above, during fabrication, ceramic slurry adopts injection mode to be filled in filling slot to the intensive insulation bus slot of the utility model, and ceramic slurry is injected filling slot Post RDBMS and formed fire-resistant fire division wall, and technique is simple.In addition, fire-resistant fire division wall forms fire division wall between burning things which may cause a fire disaster and busbar unit, and this can improve the fire resistance of bus duct, improves intensive insulation bus slot continued power ability in a fire, extends the intensive insulation bus slot continued power time in a fire.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the intensive insulation bus slot of the utility model.
In figure: busbar protecting crust 10, metallic plate 11, bolt 12, busbar 20, busbar conductor 21, Ceramic silicon rubber layer 22, the fire-resistant composite band 23 of Ceramic silicon rubber, filling slot 30.
Embodiment
By describing technology contents of the present utility model, modular construction in detail, being realized object and effect, be explained in detail below in conjunction with accompanying drawing.
Refer to Fig. 1, the intensive insulation bus slot of the utility model, roughly in rectangular-shaped, comprises busbar protecting crust 10 and the busbar unit be arranged in this busbar protecting crust 10.
Busbar protecting crust 10 is guard shields of intensive insulation bus slot; be generally metal shell; such as steel or ferrous casings; there is the effect of protection bus duct internal part; in the present embodiment; busbar protecting crust 10 is surrounded by four pieces of metallic plates 11, and two adjacent metal sheets are fixed together by bolt 12, can certainly be screwed.
Busbar unit comprises multiple busbar 20.Busbar 20 comprises the insulating barrier of busbar conductor 21 and this busbar conductor 21 coated.Insulating barrier mainly plays insulated fireproof effect to busbar conductor 21, and in the present embodiment, busbar conductor 21 is coated with Ceramic silicon rubber layer 22, is surrounded with the fire-resistant composite band 23 of Ceramic silicon rubber outside Ceramic silicon rubber layer 22.Ceramic silicon rubber layer 22 outside busbar conductor 21 and the fire-resistant composite band of wrapped Ceramic silicon rubber 23 form described insulating barrier.The fire-resistant composite band 23 of Ceramic silicon rubber; flame-retardant effect can be played; flame-retardant excellent performance; even if exceed fire endurance burning still ablation can form hard containment vessel; containment vessel can prevent flame from extending to busbar conductor 21 further; thus the busbar conductor 21 that protection is positioned at the fire-resistant composite band of Ceramic silicon rubber is not damaged, and guarantees the normal usage function of busbar 20, improves the fail safe of product.
The plurality of busbar 20 side by side parallel arranges formation entirety, as busbar unit.Be formed with filling slot 30 between busbar protecting crust 10 and this busbar unit, be injected with ceramic slurry in filling slot 30, ceramic slurry is injected filling slot Post RDBMS and is formed fire-resistant fire division wall.Inlet (not shown) can be offered in order to inject ceramic slurry on busbar protecting crust 10.
In order to improve its fire-resistant effect further, the inner and/or outer fireproof coating that is provided with of busbar protecting crust forms flame-retardant coating layer (not shown).
In sum, be injected with ceramic slurry in the filling slot 40 of the intensive insulation bus slot of the utility model, ceramic slurry is injected filling slot Post RDBMS and is formed fire-resistant fire division wall.When manufacturing bus duct, ceramic slurry adopts injection mode to be filled in filling slot 40, and technique is simple; In addition, fire-resistant fire division wall forms fire division wall between burning things which may cause a fire disaster and busbar unit, and this can improve the fire resistance of bus duct, improves intensive insulation bus slot continued power ability in a fire, extends the intensive insulation bus slot continued power time in a fire.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art also can make multiple change accordingly, but to be anyly equal to the utility model or similar change all should be encompassed in the scope of the utility model claim.
