Description

Intensive anti-harmonic wave fireproof bus duct

Technical field

This utility model relates to electrical equipment technical field, is specifically related to transmission facility bus duct.

Background technology

Bus groove transmission has the many advantages such as more safety, the bus of prior art compared to traditional multiway cable Groove typically use what square shape was closed bus duct in bus by going master slice to insulate, it uses A3 steel standby, such as patent name Fireproof bus duct transmission of electricity, application publication number for improving are CN103208765A, Shen Qing Publication day is 013.07.17, application number Being the fireproof bus duct that improves of disclosure of the invention of 2013100865577, including cell body, cell body is by upper cover plate, lower cover and two Individual side plate is constituted, and upper cover plate two ends are bent into lower hem the most inside, and lower cover two ends are bent into upper hem, both sides the most inside Plate bent outward is converted into transverse slat, is locked by securing member between the transverse slat of biside plate and upper cover plate, lower cover, is filled with absolutely in cell body Edge body, is provided with insulating base in cell body, insulating base include insulated leg, lower insulated leg and be fixed on upper and lower insulated leg it Between bus, biside plate has radiator structure, on lower cover, place has rhone inside the upper hem.Its both sides of this invention Having heat radiation inclined hole on plate, the bending of upper cover plate, lower cover has a certain degree, and prevents rainwater from entering heat radiation inclined hole, has certain Insulation effect and fire protecting performance.But, the same A3 steel bus duct using square shape carries cross section at square shape and easily produces back Road forms eddy current, thus produces heat, thus also affects radiating effect, and outside rainwater still there may be the peace within entering Full blast danger.

Utility model content

The purpose of this utility model is contemplated to solve the deficiency of prior art, and a kind of barrier propterty provided is good, no Produce eddy current, the intensity anti-harmonic wave fireproof bus duct of good heat dissipation effect safety.

This utility model is to use following technical solution to be attained in that

A kind of intensive anti-harmonic wave fireproof bus duct, it is to arrange busbar in the inner housing of inner port font, busbar it Between form insulating barrier between the gap that is filled in of master slice fusing by going, be additionally provided with shell body layer, inner and outer shell outside inner housing Between be provided with fire prevention silk floss, described inner and outer shell at least one side be corrosion resistant plate face, its lap is A3 steel plate.

The three-back-shaped inner and outer shell of described formation is all that a corrosion resistant plate is fixed together with flute profile A3 steel, two Person can be to be fastened and connected or be welded and fixed together.

Further, the corrosion resistant plate face in described inner and outer shell is that coplanar is arranged, it is also possible to for setting of staggering, this is stainless Steel plate is 304,316 shape steel plates.

This utility model uses above-mentioned technical solution can reach to provide the benefit that:

This utility model is owing to have employed three-back-shaped sealing structure, thus can be effectively prevented the infiltration of outside rainwater, Safer, simultaneously because have employed at least one side is corrosion resistant plate face, its lap is A3 steel face, and such housing will not produce whirlpool Stream, because without generation heat, thus being also better achieved heat radiation, efficiently solve a difficult problem for eddy current and heat radiation.

Accompanying drawing explanation

Fig. 1 is cross-sectional view of the present utility model.

Description of reference numerals: 1, shell body 2, fire prevention silk floss 3, inner housing 4, Muscovitum 5, busbar 1-1, A3 steel plate surface, 1- 2 corrosion resistant plate faces, 3-1, A3 steel plate surface, 3-2 corrosion resistant plate face.

Detailed description of the invention

Below in conjunction with specific embodiment, the technical program is explained in detail.

As it is shown in figure 1, intensity of the present utility model anti-harmonic wave fireproof bus duct is made up of three-back-shaped inner and outer shell, internal Busbar 5 is set in the inner housing 3 of hollow, between the gap being filled in by going master slice 4 to melt between busbar 5, forms insulation Layer, is additionally provided with shell body layer 1 outside inner housing 3, be provided with fire prevention continuous 2 between inner and outer shell 1,3, and described inner and outer shell is at least One side is corrosion resistant plate face (1-2,3-2), and its lap is A3 steel plate, and in the present embodiment, wherein one side is corrosion resistant plate face, remaining Three is A3 steel plate surface, and A3 steel plate surface and corrosion resistant plate face are for being fastened and connected, naturally it is also possible to use other connection sides such as welding Formula.

In embodiment, the corrosion resistant plate face in described inner and outer shell can be that coplanar is arranged, and as other enforcement can be Staggering setting, this corrosion resistant plate is 304 or 316 shape steel plates, and this sample loading mode radiating effect is more preferable.

Above-described is only preferred implementation of the present utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these all belong to In protection domain of the present utility model.
