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; Described busbar unit comprises multiple busbar, and described busbar comprises the insulating barrier of busbar conductor and this busbar conductor coated, and described multiple busbar side by side parallel arranges formation entirety; Be provided with circulating line in described intensive insulation bus slot, in circulating line, be connected with water or gas.
As mentioned above, circulating line is provided with in the intensive insulation bus slot of the utility model, water or gas is connected with in circulating line, heat in concentration bus duct is passed to circulating line and takes heat out of concentration bus duct by circulating line, thus can cooling effect be played, 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 lateral cross section structural representation of the intensive insulation bus slot embodiment 1 of the utility model.
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.
Embodiment 1
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 22 of busbar conductor 21 and this busbar conductor 21 coated.Insulating barrier 22 pairs of busbar conductor 21 mainly play insulating effect, can be heat-shrink tube, material that preferably can also be fire-resistant, such as Ceramic silicon rubber composite band, fire-resistant isinglass belt or both mixing.In the present embodiment; insulating barrier 22 adopts Ceramic silicon rubber composite band; 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 Ceramic silicon rubber composite band is not damaged; guarantee the normal usage function of busbar 20, improve the fail safe of product.
The plurality of busbar 20 side by side parallel arranges formation entirety, as busbar unit.Be provided with circulating line 30 between busbar protecting crust 10 and busbar unit, have water W or the gas of flowing in circulating line 30, in the present embodiment, circulating line 30 is arranged between busbar protecting crust 10 and busbar unit.Certainly, circulating line 30 can also be arranged between the adjacent busbar 20 of busbar unit.
In addition, circulating line 30 is not limited to said structure shape, can also be multiple little circulating line.
Preferably, described intensive insulation bus slot also comprises at least one air-supply heat abstractor, and this air-supply heat abstractor is arranged in described intensive insulation bus slot one end or described intensive insulation bus slot.Which further improves cooling-down effect.
Embodiment 2
The present embodiment is similar to Example 1, its difference is: intensive insulation bus slot also comprises a metal-back, it is inner that metal-back is arranged on busbar protecting crust, busbar unit is arranged in metal-back, be provided with circulating line between metal-back and busbar unit, between metal-back and busbar protecting crust, be also provided with circulating line.Water or the gas of flowing is had in circulating line.
What deserves to be explained is, the present embodiment can also have other to convert, such as, be coated with refractory matter or ceramic powder at metal-back, is provided with circulating line between metal-back and busbar unit; Or circulating line is set outside described metal-back, between metal-back and busbar unit, is provided with refractory matter or ceramic powder.
The main fixed support effect of metal-back, in the present embodiment, metal-back is surrounded by four pieces of metallic plates, and two free ends of each metallic plate are all inwardly vertically bent to form covering portion.
In sum, circulating line 30 is provided with in the intensive insulation bus slot of the utility model, water or gas is connected with in circulating line 30, heat heat conduction in concentration bus duct is passed to circulating line 30 and takes heat out of concentration bus duct by circulating line, thus can cooling effect be played, 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.
