Embodiment
By describing technology contents of the present invention, modular construction in detail, being realized purpose and effect, be explained in detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, the first embodiment that it has disclosed the intensive insulation bus slot of the present invention comprises busbar protecting crust 10 and is arranged at the interior some busbars 20 of this busbar protecting crust 10 that these busbars 20 are parallel to each other to be close to and arrange.Be provided with ceramic silicon rubber heat-insulation layer 30 between busbar protecting crust 10 and some busbars 20.
Ceramic silicon rubber heat-insulation layer 30 flame-retardant excellent performances; still can ablation form hard containment vessel even surpass the fire endurance burning; containment vessel can prevent that flame from further extending to the busbar conductor; thereby protection is positioned at the busbar 20 of ceramic silicon rubber heat-insulation layer 30 not to be damaged, and guarantees the normal usage function of busbar.
Ceramic silicon rubber heat-insulation layer 30 can also be further ceramic silicon rubber insulating foam layer, this be because ceramic silicon rubber insulating foam layer except the flame-retardant characteristic with ceramic silicon rubber, have also that density is little, quality is light, the characteristic such as heat insulation, insulation, this can stop external high temperature to conduct to busbar 20 inside, guarantees the normal usage function of busbar.When breaking out of fire; external high temperature is protected the unlikely temperature of busbar in ceramic silicon rubber foaming insulation layer and is raise due to the heat insulating function of ceramic silicon rubber foaming insulation layer; avoid the phenomenons such as short circuit that raise and to bring because of busbar temperature, guarantee the normal operation of busbar.
Ceramic silicon rubber insulating foam layer is preferably formed by the material mixture ratio of 60～100 parts, silicon rubber, 20～100 parts of silicon dioxide, 1～20 part of silicone oil, 0.1～10 part of coupling agent, 20～120 parts of Vitrified powders, 10～35 parts of blowing agents, 1～10 part of blowing promotor, 5～30 parts of components of fire retardant.
