Description
Technical field
The utility model is related to fire-fighting distribution technique field, the attachment device of specifically a kind of intensity fireproof bus duct.
Background technology
With the fast development of China's economy, the construction of modernization is higher and higher to the safety requirements of power Transmission main line,
Currently, existing bus-bar slot connecting apparatus, mainly formed by being conductively connected block, collets and bolt, different bus ducts it is same
Phase conductor connector is mutually stacked together, and is separated by collets, then by being conductively connected block, collets and bolt cooperation conductor
Connector is fixed, and bolt is only cased with common insulating sleeve, and by the separation of common insulating sleeve, there are be easily damaged at insulation tube
Lead to short circuit problem, and common insulation tube meets high temperature and dissolves easily again, there are certain danger.
Utility model content
The purpose of this utility model is to provide a kind of attachment devices for fireproof bus duct, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions：
A kind of attachment device of intensity fireproof bus duct, including metal shell, flame resistant heat insulation material, for connecting busbar
Slot conductor is conductively connected block and hot-face insulation cushion block, and block is conductively connected and hot-face insulation cushion block is located at outer metal wherein described
Shell is conductively connected block and is bolted with hot-face insulation cushion block by running through to connect, and it is exhausted to be set with fire resisting on the connection bolt
Edge casing.
As further program of the utility model：It the hot-face insulation cushion block and is conductively connected on block and is provided with mounting hole,
The diameter of the mounting hole is matched with the diameter for being sleeved on the hot-face insulation casing connecting on bolt.
As further program of the utility model：The flame resistant heat insulation material is positioned over outer metal shell and interior metal
Between the gap of shell.
As further program of the utility model：In order to ensure that the reliability of connection structure, the metal shell are adopted
It is hindered with being filled between outer metal shell and interior metal shell double shielding and the gap between outer metal shell and interior metal shell
Fire heat-barrier material.
Compared with prior art, the utility model has the beneficial effects that：
A kind of attachment device of fireproof bus duct passes through rational structural improvement, especially hot-face insulation cushion block
Use two layers of protection with connected with outer casing, further ensure the reliability and fire resistance of connection structure, at the same also keep away into
Aqueous vapor and flame enter from connected with outer casing leads to short circuit, and can play the role of protecting hot-face insulation cushion block.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2, Fig. 3 are the actual use schematic diagrames of the utility model.
In figure：1- flame resistant heat insulation materials, 2- connections bolt, 3- be conductively connected block, 4- bus ducts conductor, in 5- outside metal
Shell, 6- outer metal shell, 7- insulated fireproofs casing, 8- hot-face insulations cushion block, 9- shell fastening bolts.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1~3, in the utility model embodiment, a kind of attachment device of intensity fireproof bus duct, including it is interior
It is equipped in metal shell 5 and outer metal shell 6, the interior metal shell 5 and outer metal shell 6 for connecting bus duct conductor 4
Be conductively connected block 3 and hot-face insulation cushion block 8；It is conductively connected block 3 described in wherein and hot-face insulation cushion block 8 is located at interior metal shell
In 5, the both ends for being conductively connected block 3 are contacted with the bus duct conductor 4 of both sides respectively, and hot-face insulation cushion block 8 is then used to separate mother
Wire casing conductor 4 is conductively connected block 3 and hot-face insulation cushion block 8 and is connected by perforative connection bolt 2.
Block 3 and hot-face insulation cushion block 8 will be conductively connected the compression of bus duct conductor 4 to connect by connecting bolt 2
Bus duct is set with insulated fireproof casing 7 on the connection bolt 2, avoids connection bolt 2 and bus duct conductor 4 and conduction
The electric block of connection, which is in direct contact, leads to short circuit, and can prevent flame combustion.
The flame resistant heat insulation material 1 is filled between outer metal shell 6 and interior metal shell 5, can be more effectively prevented
It prevents the intensity of a fire to burn and acted on every gesture when fire occurs, it is short to be avoided that aqueous vapor causes from connecting portion infiltration again by double shielding
Road, and the bolt installation of hot-face insulation cushion block 8 is protected to reduce abrasion
The flame resistant heat insulation material 1 is filled in connector, and insulated fireproof casing 7 is the insulated fireproof set for being set with bolt
Pipe.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed by the utility model, this
For the technical staff in field according to disclosed technology contents, not needing performing creative labour can be special to some of which technology
