Description
Technical field
The present invention relates to a kind of fire resistant busbars.
Background technique
With the rapid development in city, skyscraper is more and more, and building power load sharply increases therewith, original
Wire and cable because its capacity is small, branch is inconvenient, is not easy to the reasons such as boundling management, gradually by capacity big, branch and
The convenient bus duct of boundling management replaces.
Bus duct is widely used in the accented terms such as power Transmission main line and the fire-fighting emergent equipment main line of fire control equipment
Mesh, such as in the important engineerings such as commercial square, subway, airport, office building, entertainment place, communal facility.Therefore, bus
The safety and stability performance of slot product is most important, and requirement of the China to busway product security performance is also higher and higher, it is desirable that really
The power Transmission backbone of guarantor's building continued power in earthquake relief work.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, provide a kind of bus duct of fire safe type.
A kind of fire resistant busbar, including main body frame, the main body frame are spelled by upper and lower lids and left and right side plate
It connects, the left and right side plate includes upper plate and lower plate, passes through several bolt phases between the upper plate and lower plate
Even；The lower end of the upper plate is equipped with groove, and the upper end of lower plate is the protrusion to match with groove；The side of the groove is equipped with laterally
The first waist type groove, raised side is equipped with the second vertical waist type groove and lateral bar shaped deep gouge, in the bar shaped deep gouge
Filled with asbestos；One end of the bolt is rectangle, and is embedded on upper plate inner surface in corresponding rectangle deep gouge, bolt
The other end passes through the first waist type groove and the second waist type groove and is screwed on nut；Several L shapes are additionally provided in the main body frame
One end of elastic slice, the L shape elastic slice is connected with the inner surface of main body frame, and the other end is connected to electrical conductor inside main body frame
Outer surface on.
In order to promote the elastic deformability of L shape elastic slice, the material of the L shape elastic slice is magnetism-free stainless steel, L shape elastic slice
Silicone protective layer is also coated on outer surface.
In order to promote fire prevention temperature resistant capability, asbestos gauge is equipped on the inner surface of the upper and lower lids, the asbestos gauge
With a thickness of 4-8mm.
In order to obtain lighter fire resistant busbar, the material of the upper plate is magnesium alloy.
The utility model has the advantages that
1, side plate is split as to the structure of upper plate and lower plate, can be adjusted convex by adjusting the distance between upper and lower plate
The depth in groove is played, L shape elastic slice can be tightly pressed against the upper and lower surfaces of electrical conductor, to make in charge conductor
Gap between each flat conductor and insulation board minimizes, and external heat is prevented to be transferred in electrical conductor by air,
To make bus duct fail.
2, the setting of multiple L shape elastic slices can make internal electrical conductor " hanging " that the inside of main body frame be arranged in,
It prevents heat to be transferred in electrical conductor by main body frame, causes electrical conductor temperature to increase, to can not be in a fire
Fire-fighting equipment power supply.

Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, is not intended to limit the scope of the present invention..
As shown in Figure 1-3, a kind of fire resistant busbar, including main body frame, the main body frame is by upper and lower lids 1
It is spliced with left and right side plate 2, the left and right side plate 2 includes upper plate 21 and lower plate 22, and the material of the upper plate 21 is
Magnesium alloy.
It is connected between the upper plate 21 and lower plate 22 by several bolts；The lower end of the upper plate is equipped with groove, such as
Shown in Fig. 4, the upper end of lower plate is the protrusion to match with groove；The side of the groove is equipped with the first lateral waist type groove, protrusion
Side be equipped with the second vertical waist type groove and lateral bar shaped deep gouge, be filled with asbestos in the bar shaped deep gouge；The spiral shell
One end of bolt is rectangle, and is embedded on upper plate inner surface in corresponding rectangle deep gouge, and the other end of bolt passes through the first waist
Type groove and the second waist type groove are simultaneously screwed on nut；Several L shape elastic slices 4, the L shape elastic slice are additionally provided in the main body frame
4 one end is connected with the inner surface of main body frame, and the other end is connected to inside main body frame on the outer surface of electrical conductor 3.
The material of the L shape elastic slice 4 is magnetism-free stainless steel, is also coated with silicone protective layer on the outer surface of L shape elastic slice 4.
Be equipped with asbestos gauge on the inner surface of the upper and lower lids 1, the asbestos gauge with a thickness of 4-8mm.
In use, first adjusting the position of upper plate 21, until L shape elastic slice 4 is tightly pressed against electrical conductor 3, and occur small
Deformation, at this point, tightening nut, until upper plate 21 and lower plate 22 are tightly bitten in the combination of nut and bolt, and makes upper plate 21
Micro-strain occurs for groove, and the asbestos in bar shaped deep gouge are pressed on deep gouge, thus between obtaining zero between good airproof performance, electrical conductor
Gap and electrical conductor " hanging " is placed on the fire resistant busbar in main body frame.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
