Description

A kind of intensive fireproof bus duct

Technical field

The utility model relates to bus duct technical field, is specially a kind of intensive fireproof bus duct.

Background technology

Modern high-rise building and large-scale workshop need huge electric energy, and the powerful electric current of hundreds and thousands of amperes will select safe and reliable transmission equipment needed for this huge load.Bus duct is a power distribution equipment efficiently carrying electric current, and fireproof bus duct is essential in heavy construction, but conventional air type fireproof bus duct takes up room greatly, and structure is loaded down with trivial details.

Utility model content

The utility model, according to above-mentioned the deficiencies in the prior art, provides a kind of intensive fireproof bus duct.

In order to achieve the above object, the technical scheme that the utility model is taked is:

A kind of intensive fireproof bus duct, comprise busbar, outside H section bar, inner H section bar, inner U-shaped material and the U-shaped material in outside, described outside H section bar and the U-shaped material in outside are respectively arranged with two, total closed type overall structure is mutually pieced together by bolt, described busbar upper, below is fixed respectively by inner H section bar, a left side for busbar, right is fixed respectively by the U-shaped material in inside, the both ends of described outside H section bar are provided with the connecting lateral plate of protection busbar, described outside H section bar and inner H section bar, the space formed between inner U-shaped material and the U-shaped material in outside is equipped with fire prevention filler.

As preferably, described fire prevention filler is PLASTIC LAMINATED and anti-guncotton.

As preferably, described busbar is enclosed with polyester film and mica tape.

As preferably, described outside H section bar, inner H section bar, inner U-shaped material, outside U-shaped material are swage material surface spraying fireproof plastic.

As preferably, described busbar is intensive arrangement.

The beneficial effects of the utility model are:

Bus duct of the present utility model adopts two-layer housing, and surface of shell sprayed fire proofing is moulded, and between two-layer housing, filling has PLASTIC LAMINATED and anti-guncotton; double shielding is served to the fire-resistant of busbar, strengthens degree of protection, and busbar is enclosed with mica tape; further ensure the anti-flammability of busbar, safe and reliable.

Accompanying drawing explanation

The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:

Fig. 1 is the bus duct stereogram of a preferred embodiment of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is A-A structural representation of Fig. 2;

Mark in figure: 1-outside H section bar, 2-inner H section bar, 3-fire prevention filler, 4-busbar, 5-inner U-shaped material, 6-outside U-shaped material, 7-connecting lateral plate.

Embodiment

All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and (or) step, all can combine by any way.

Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.

As shown in Figure 1 to Figure 3, a kind of intensive fireproof bus duct, comprise busbar 4, outside H section bar 1, inner H section bar 2, inner U-shaped material 5 and the U-shaped material 6 in outside, the U-shaped material 6 of described outside H section bar 1 and outside is respectively arranged with two, total closed type overall structure is mutually pieced together by bolt, described busbar 4 upper, below is fixed respectively by inner H section bar 2, a left side for busbar 4, right is fixed respectively by the U-shaped material 5 in inside, the both ends of described outside H section bar 1 are provided with the connecting lateral plate 7 of protection busbar 4, described outside H section bar 1 and inner H section bar 2, the space formed between inner U-shaped material 5 and the U-shaped material 6 in outside is equipped with filler 3 of preventing fires, described fire prevention filler 3 is PLASTIC LAMINATED and anti-guncotton.

Described busbar 4 is enclosed with polyester film and mica tape, and busbar 4 is intensive arrangement, and described outside H section bar 1, inner H section bar 2, inner U-shaped material 5, outside U-shaped material 6 are swage material surface spraying fireproof plastic.
