Description
Technical field
The present invention relates to power Transmission main lines, more particularly, it relates to the minerals with good fire resistance
Enclosed busbar slot.
Background technique
With the rapid development in city, skyscraper is more and more, and building power load sharply increases therewith, original
Wire and cable is because its capacity is small, branch is inconvenient, is not easy to the reasons such as boundling management, gradually big, the branch side by capacity
Just, the convenient bus duct of boundling management replaces.Bus duct is widely used in the power Transmission main line of fire control equipment and fire-fighting is answered
The key projects such as anxious equipment main line, such as in the important engineering such as hotel, airport, subway, therefore the safety of busway product
Stability is most important.
But there is also some disadvantages for bus duct, for example, due between bus duct boundling arrangement would generally generate compared with
Big heat, the heat dissipation problem of bus duct is also a hang-up for perplexing bus duct research staff all the time, if bus
Slot does not have necessary heat dissipation performance, once high temperature caused by the connection busbar in bus duct is unable to disperse in time, just very
Fire safety hidden danger may be brought.And bus duct used at present works under long-term adverse circumstances and is not able to maintain good insulation
State, overload capacity is not strong, and breakdown often occurs, flashover, generates phenomena such as vortex.
Summary of the invention
The object of the present invention is to provide a kind of minerals enclosed busbar slot, thermal diffusivity is strong, have good fire resistance and
Securely and reliably.
The technical solution adopted by the present invention is that:
According to an aspect of the invention, there is provided minerals enclosed busbar slot, which is characterized in that including bus duct sheet

It is connected by connector, is equipped with outer panel, respectively the first outer panel and the second outer panel on the outside of the multiphase conductor, described the
One cover board is connect with the top of first outer panel, and the 4th cover board is connect with the top of second outer panel, described
Every phase conductor is externally provided with insulating layer, is filled with flake asbestos mineral filler in the cover board, the conductor is relative to the cover board
Side be equipped with bottom plate, the bottom plate be equipped with M shape reinforcing rib, the reinforcing rib with a thickness of 2.0-3cm.
In some embodiments, it is uniformly provided with arc cooling fin on first outer panel and second outer panel,
First outer panel and second outer panel are in " [" type structure, and both ends extend outward.
In some embodiments, the cover board is equipped with V-type reinforcing rib, is coated with fire resistant coating on the cover board.
In some embodiments, it is coated with fireproof coating outside every phase conductor, the fireproof coating is coated with cloud
Master tape.
In some embodiments, epoxy resin layer is filled between the multiphase conductor and the refractory slab.
Minerals enclosed busbar slot provided by the invention, thermal diffusivity is strong, has good fire resistance and safe and reliable.
