Description
Technical field
The utility model relates to a kind of bus duct structure, in particular a kind of casting type fireproof bus duct.
Background technology
Modern high-rise building and large-scale workshop need huge electric energy, and carry these electric energy must select safe and reliable transmission equipment.Bus duct system is a power distribution equipment efficiently carrying electric current, is particularly useful for the power delivery of high-rise and large-scale plant.Traditional bus duct generally comprises shell and is arranged on the copper bar of enclosure for conducting electricity, copper, dielectric between row and shell, is utilized to fix, the bus duct of traditional this structure does not have fire-proof function, when the burst accident such as operational environment breaking out of fire of bus duct, bus duct is heated and can not works, the normal work of the whole electric power system of direct impact, may cause heavy losses time serious.In the event of a fire, can continue the integrality keeping circuit, fireproof bus duct is absolutely necessary, and ensures that power supply is uninterrupted, when can ensure that overload or short circuit occur bus duct, does not cause bus duct burn and cause electrical fire simultaneously.
Utility model content
The purpose of this utility model is: provide a kind of casting type fireproof bus duct, has waterproof, fire prevention, the function such as fire-resistant, anticorrosion, explosion-proof.For realizing this object, the utility model adopts following technical scheme:
A kind of casting type fireproof bus duct, comprise pouring bus groove, it is characterized in that: described pouring bus groove is coated with flame retardant coating, described flame retardant coating comprises PLASTIC LAMINATED and is coated on the outer field fire resistant coating of PLASTIC LAMINATED.Casting type bus duct adopts the reasonably tight laminated structure of " sandwich " phase line, compact appearance, and volume is little, and bus-bar system is moved hot good, and external sheath PLASTIC LAMINATED, PLASTIC LAMINATED applies fire resistant coating, double-deck fire prevention, composition flame retardant coating.
Further, described pouring bus groove comprises copper bar and insulating resin, and described insulating resin is epoxy resin composition, is cast between busbar and the surrounding of busbar.
Further, also comprise insulated support, described insulated support is arranged at the end at bus two ends, and described insulated support is BMC composite material.At bus straightway bus two ends, place arranges insulated support and fixes copper bar right overhead, and BMC BMC has excellent electric property, mechanical performance, thermal endurance, chemical resistance, adapts to again various moulding process, can meet the requirement of various product to performance.
Further, described PLASTIC LAMINATED thickness is 20mm, and described fire resistant coating thickness is 5mm.
Compare prior art, casting type fireproof bus duct fire prevention of the present utility model, waterproof, explosion-proof, anticorrosion and fire resistance are all greatly improved, and especially fire resistance period and refractory temperature are all higher.
Accompanying drawing explanation
Fig. 1 is the utility model casting type fireproof bus duct structural representation;
Fig. 2 is front view of the present utility model;
Fig. 3 is the cutaway view in A-A face in Fig. 2;
In figure, 1-insulated support, 2-epoxy resin composition, 3-copper bar, 4-PLASTIC LAMINATED, 5-fire resistant coating.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is further described.
As Figure 1-3, a kind of casting type fireproof bus duct, comprises pouring bus groove, and described pouring bus groove is coated with flame retardant coating, and described flame retardant coating comprises PLASTIC LAMINATED and is coated on the outer field fire resistant coating of PLASTIC LAMINATED.Epoxy resin composition is cast between busbar and the surrounding of busbar, and the insulated support of BMC composite material is fixed on the end at bus two ends.PLASTIC LAMINATED after the bus duct external sheath 20mm poured into a mould, PLASTIC LAMINATED applies the fire resistant coating after 5mm, forms fire resistant busbar.
When two cast fireproof bus ducts connect, first pour into a mould copper bar with epoxy resin composition, make pouring bus groove, two bus ducts poured into a mould connect, and then carry out coated with PLASTIC LAMINATED, PLASTIC LAMINATED skin coating fire resistant coating.
Casting type fireproof bus duct of the present utility model requires to test according to GA/T537-2005, and my company's refractory busbar fire resistance period is 45 minutes, flame temperature 750 DEG C-800 DEG C, and refractory busbar test method is as follows:
Test piece to be two pieces total length the be bus (joint must be contained in centre) of 6 meters, except connecting the top of outer lead, all the other positions are all in stove.In order to check the integrality of test specimen circuit, necessary electrical connection should be carried out, be connected with transformer, fuse, the wire being connected to L1, test specimen, bus, bulb.Regulate transformer after switching on power, progressively rise to rated voltage, and make electric current in circuit be 0.25A by the configuration of load.Then light a fire, when reaching 50 DEG C close to the electric thermo-couple temperature at test specimen center in fire test furnace, all measuring instrument timing are started working, on-test.Lower than 30min, should not stop for continuing energising 15min after fire for the fire time.Namely total testing time is the cooling time supplying the fire time to add 15min.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
