Abstract
The utility model relates to an insulated conductor or a cable with a heat shielding device. The utility model takes moulding high-frequency porcelain blocks with high-temperature resistance and good insulating property as the insulative materials and adopts a shell of double layer composed of an inner layer and an outer layer. The surface of the casing of the outer layer is also coated with fireproof paint in order to increase a fireproof effect. Apart from good electric property and use property of a general bus slot, the utility model also has a fireproof performance of high temperature resistance. The utility model is suitable for being used in large buildings, such as new buildings, markets, public and recreation places, etc.
Description
The utility model relates to insulated electric conductor or the cable of being with thermal shield apparatus.
Bus duct also claims the bus mains system, it is the essential device of building input electric power, bus duct is by current (being generally 4 lines), between housing and conductor, insulating material between conductor and housing is formed, it has carries electric current big, overload capacity is strong, draw characteristics such as branch power supply convenience, and selected for use widely, but the plain edition bus duct does not give due consideration to fire resistance, cause and at high temperature to work, and the outfit of various fire protection equipments be unable to do without the supply of electric power mostly, in case breaking out of fire, supply line produces fault, and the various fire-fighting equipments of electricity consumption that need all can't play a role, and heat must cause bigger loss.Therefore, present most of architectural designs have all proposed the demand of fire resistant busbar, need to develop a kind of novel fire resistant busbar for this reason.
The purpose of this utility model provides the fire resistant busbar novel product that 30 minutes fire endurances in a kind of heating curve that can satisfy building element fire resistance test method rule regulation require.
The purpose of this utility model realizes with following technical proposals, the one, adopt high temperature resistantly, and the mold pressing high frequency porcelain piece of good insulation preformance is made insulating material; The 2nd, the double Shell of the inside and outside double-layer structure of employing, the surface of outer casing also can be coated with one deck fireproof paint again for increasing flameproof effect.
Accompanying drawing 1 is the cross section structural representation of the utility model fire resistant busbar, and Fig. 2 is the syndeton schematic diagram of current, and 1 is current among the figure; 2 is air layer; 3 are the protection conductor, and 4 is the bus groove case internal layer, and 5 is fireproof paint; 6 is the bus duct shell; 7 is collets, and 8 pay for the housing connecting bolt, and 9 for connecting copper bar; 10 is clamping plate and be connected side plate, and 11 is anchor bolt nut.
Provide the embodiment of the utility model fire resistant busbar in conjunction with the accompanying drawings.
Current 1 is positioned at bus duct middle part as shown in Figure 1, between each conductor with air layer 2 insulation, and with collets 7 supporting conductors 1 with make phase insulation, collets be high temperature resistant, do not burn, do not wear out, the mold pressing high frequency porcelain piece (AL of good insulation preformance
2O
3); clad bus groove case internal layer 4 around the collets 7; it is with the channel steel shape thin plate section bar overlap joint of flange and pays 8 with connecting bolt by four and is formed by connecting; side at internal layer is glued with protection conductor 3; bus duct shell 6 is made up of four blocks of channel steel shape thin plate section bars; about two with last; pay 8 connections with the spiral shell inspection respectively for following two; and also pay with the thin plate section bar of internal layer and to connect into an integral body with bolt; between internal layer and shell, form four air layers 2 up and down; as the air heat-insulation layer between housing; such double-layer shell structure has good dust-proof and water resistance, has also improved fire resistance simultaneously; shell structure makes bus duct have favorable rigidity and fastness; also alleviated simultaneously the weight of bus duct, case surface scribbles fireproof paint 5, has further improved the fire resistance of bus duct.The syndeton of bus duct as shown in Figure 2, the both sides of each current 1 overlap respectively and connect copper bar 9, each connects and all is lined with collets 7 between copper bar, the outside is equipped with clamping plate and is connected side plate 10, tightens wearing with anchor bolt nut at last, and connects in aggregates.
The utility model fire resistant busbar has outside the good electrical performance and serviceability of general bus duct, also has the fire resistant performance, try through side, the requirement of 30 minutes fire endurances of standard GB 9978 " building element fire resistance test method " regulation can be satisfied, the fire prevention power reguirements of various buildings can be applicable to.
Claims (3)
1. fire resistant busbar, it is made up of current, insulating material and shell, it is characterized in that insulating material is a mold pressing high frequency porcelain piece high temperature resistant, good insulation preformance; Shell is inside and outside two-layer double Shell.
2. according to the said fire resistant busbar of claim 1, it is characterized in that scribbling fireproof paint on the surface of outer casing.
