Description
Technical field
The present invention relates to electrical equipment technical fields, and in particular to a kind of fireproof bus duct.
Background technique
Bus duct is new circuit mode developed by the U.S., referred to as " Bus-Way-System ", it is with copper
Or aluminium as conductor, with non-alkene insulating supporting, be then attached in metallic channel and the novel conductor that is formed.Japanese really practical
Using being at Showa 29 years (i.e. 1954), bus duct is developed from then on.Nowadays it builds in high level, factory etc. electrically sets
At indispensable wiring mode in standby, electric system.Due to the needs of the various building electric power such as building, factory, and this
Kind increased trend year by year is needed, using original circuit wiring pattern, i.e. poling mode, when construction, brings many difficulties,
Moreover, when distribution system to be changed, to make its become simple it is some be nearly impossible, however, if using bus duct
Words are very easy to achieve the goal, in addition also building can be made to become more beautiful.For economic aspect, bus duct
Compared with cable, price is some for itself, but uses compared with the various attachmentes comprising wiring and entire electric system
Bus duct can make construction cost just it is cheap mostly, especially current capacity it is big in the case where, such case is with regard to more obvious.
Fire resistant busbar is by being coated with the shell of fireproof coating, the bus of looping fire-resistant isinglass belt and by refractory insulating material
Manufactured bracket composition.Multiple grooves are provided on bracket, groove is built into bus and is fixed.There is mother in one end of bus duct
Wire casing connects box, there is bus-tapping box in bus duct.Fire resistant busbar has excellent insulation performance, both can be in normal ring
It is used continuously, and can be used continuously one hour or more in the environment that catches fire in border, is applicable in skyscraper and critical facility,
Transmission & distribution electro ultrafiltration is played instead of fire-resisting cable.Fire resistant busbar in the prior art, in order to improve refractory ability, mostly filling is big
The fire retardant matter of amount, these substances also counteract the heat-sinking capability of bus duct while improving refractory ability.
Summary of the invention
It is an object of the invention to overcome deficiency in the prior art, providing one kind has good refractory ability bus duct,
While improving refractory ability, also there is good heat-sinking capability.
To solve prior art problem, the invention discloses a kind of fireproof bus duct, including bottom edge, side and top cover, institutes
It states bottom edge, side and top cover and surrounds a cavity；There are multiple cores, each in the cavity that the bottom edge, side and top cover surround
The external sheath of core has insulating layer, and core is intertwined by mica tape；There is the shield of " Ω " shape in the outside of core
Set has flame retardant coating between the sheath and bottom edge；Fire resisting is filled in cavity above sheath, on the inside of side, below top cover
Fire proofing；There are several grooves to lower recess on top cover.
Preferably, card slot is arranged in the inside of the side, and the top cover is inserted into card slot.
Preferably, the top cover and card slot joint are provided with refractory block.
Preferably, a heat sink is set in the cavity above sheath, on the inside of side, below top cover.
Preferably, the cross section of the heat sink is bending structure.
Preferably, fire resistant flame retardant material is filled in the groove of top cover.
Preferably, the top of cap recess two sides is provided with cover slot, the cover slot is recessed inwardly, is provided in cover slot
Cover board, the cover board are inserted in cover slot, and are connected cover board with cover slot by screw.
Preferably, fireproof coating layer is coated on top cover surface.
The invention has the benefit that the promotion of fire-protection rating is carried out to bus duct in several ways, on the cover board
Fireproof coating layer is set, for first of protection, flame is avoided to burn on the cover board；It is arranged on the cover board simultaneously several to lower recess
Groove, in groove fill fire resistant flame retardant material, for second protect, further avoid flame and continue to spread on the cover board；
Fire resistant flame retardant material is filled in the cavity formed on the downside of cover board, above sheath and on the inside of side, is protected for third road, is guaranteed female
The core of wire casing is not by influence of fire, even if can also continue to run a period of time when encountering fire；Simultaneously in sheath and bottom edge
Between be provided with flame retardant coating, be the 4th protection, the intensity of a fire can be protected to enter from bottom edge；In order to avoid flame is from cover board and side
The card slot junction on side enters, and is provided with refractory block at the position that cover board is connect with card slot；Also pass through cloud on the surface of core
Multiple cores are bundled together by female paper, play protective action to the end to core.In this way, the every aspect of bus duct carries out
Protection, when encountering fire can effective protection, resist the invasion of fire.In order to improve the heat dissipation effect of heat sink,
One heat sink is set in the cavity above sheath, on the inside of side, below top cover.Above sheath, on the inside of side, below top cover
Cavity in a heat sink is set, the cross section of heat sink is bending structure, and the top of heat sink connect with top cover, be convenient for by
Heat transmission in bus duct radiates to top cover surface, while improving fire resistance, does not influence the heat dissipation of bus duct.
In the invention, the flame retardant coating between sheath and bottom edge is using aluminium silicate wool felt at fire can be effectively prevented
Seedling burning；It is to hinder aluminium hydroxide micro powder that fire resistant flame retardant material is filled in cavity above sheath, on the inside of side, below top cover
Combustion agent is blended in epoxy resin embedding adhesive；The fire resistant flame retardant material filled in top cover upper groove is also that aluminium hydroxide micro powder is fire-retardant
Agent is blended in the mixture of epoxy resin embedding adhesive；The surface coated mica tape of core is a kind of refractory insulating material, is had excellent
Good high temperature resistance and flame resistance energy, core surface have insulating layer, can prevent core from leaking electricity, cause safety accident.
