Abstract
The utility model relates to a refractory bus slot with a refractory connector and a plug. On the basis of the existing refractory bus slot, the utility model adopts refraroty 95 porcelain as the connectors of the bus slot and insulating material of the plug, and the structure is correspondingly improved. Owing to the high temperature resistance and the insulating performance of the 95 porcelain, the utility model can resist high temperature of 1700 DEG C, and the bus slot can be assured to continuously work for 1.5 hours in fire environment.
Description
The utility model relates to fire resistant busbar, relates in particular to the fireproof bus duct with fire safe type joint and connection-peg.
Fire resistant busbar generally is applied to skyscraper and some critical facilitys, and its electric property and fire resistance are had relatively high expectations.Because skyscraper and some critical facilitys, in case breaking out of fire, emergency power supply and fire-fighting power supply were required to continue power supply more than 0.5 hour in fire, make emergency lighting and fire pump starting operation, to guarantee withdrawing and fire demand water of personnel.Though existing fire resistant busbar can satisfy continued power more than 0.5 hour, but the joint and the connection-peg of one section bus duct and another section bus duct are weak links, because of its used insulating material is common insulating material, as bakelite, it is high temperature resistant can only to reach 200 ℃, in case run into the dangerous situation of fire etc., carbonization easily, cause insulation breakdown to cause short circuit, cause supply line's interruption when the disaster relief.
The purpose of this utility model is to provide a kind of fireproof bus duct with fire safe type joint and connection-peg.This bus duct has been done improvement on joint and connection-peg, can guarantee in the environment that catches fire continuous operation 1.5 hours.
The utility model is to realize like this, on existing fireproof bus duct basis, adopted resistant to elevated temperatures 95 porcelain as the joint of bus duct and the insulating material of connection-peg, structurally done corresponding improvement, it is characterized in that joint comprises the bus connector, metal platen, collets, cup packing, connecting bolt, nut and inner casing, every phase bus connector of a bus duct is pushed down by two metal platen with every connector of bus mutually of the corresponding bus duct of another root, by two collets side by side every phase bus is separated, have circular hole on the metal platen, one end face of inner casing withstands two collets side by side, the earth bus of bus duct is pushed down in the other end, connecting bolt passes the inner casing end face, the metal platen and the gap of two collets side by side are by nut and the every mutually bus connector of cup packing with two bus ducts, metal platen and collets compress the composition one and place in the inner casing.
Above-mentioned fireproof bus duct with fire safe type joint and connection-peg, connection-peg comprises copper bar pin, insulation board, connecting bolt and nut, copper bar pin one end is an arc, the other end is a busbar joint, every phase pin is separated by insulation board, insulation board has circular hole, and connecting bolt passes the insulation board circular hole and by nut insulation board and pin pushed down.
The utility model has adopted the insulating material of resistant to elevated temperatures 95 porcelain as bus duct joint and connection-peg, and the resistance to elevated temperatures of fire resistant busbar is greatly improved, in case bus duct can use 1.5 hours continuously when having guaranteed breaking out of fire.
Fig. 1 is the fire resistant busbar stereogram, and Fig. 2 is the structural representation of cover plate above joint of the present utility model is removed, and Fig. 3 is a connection-peg structural perspective of the present utility model.
Among the figure: 1. bus, 2. refractory insulating layer 3. scribbles the shell of fireproof paint, 4. collets, 5. metal platen, 6. cup packing, 7. connecting bolt, 8. nut, 9. connection-peg connecting bolt, 10. insulation board, 11. pins, 12. inner casings.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
A kind of fireproof bus duct with fire safe type joint and connection-peg comprises the shell 3 that scribbles the slim fireproof paint of steel construction, and the bus 1 of looping refractory insulating material 2 is referring to Fig. 1.Couple together because bus duct is the bus duct by a section standard, therefore the bus connecting box is arranged at bus duct one end.In addition the bus breakout box is arranged in bus duct, have a plurality of bus connection-pegs hole on the breakout box cover plate.The bus connecting box of bus duct one end is used for being connected with another segment standard bus duct, connecting box body is made up of shell and joint, joint comprises bus connector 1, metal platen 5, collets 4, cup packing 6, connecting bolt 7, nut 8 and inner casing 12, every phase bus connector 1 of a bus duct is pushed down by two metal platen 5 with every connector of bus mutually 1 of the corresponding bus duct of another root, be used to interconnect, by two collets 4 side by side every phase bus is separated, collets are made by 95 porcelain, this 95 porcelain has great high-temperature resistant and insulation property, high temperature resistantly reach 1700 ℃, be enough to guarantee bus duct continuous firing 1.5 hours under the environment that catches fire; Have circular hole on the metal platen 5, inner casing 12 1 end faces withstand two collets 4 side by side, bus duct earth bus 1 is pushed down in the other end, connecting bolt 7 passes inner casing 12 end faces, metal platen 5 and the gap of two collets 4 side by side, by nut 8 and cup packing 6 every connector of bus mutually 1, metal platen 5 and the collets 4 of two bus ducts are compressed and to form one and place in the inner casing 12, referring to Fig. 2.
With the corresponding connection-peg in bus duct bus connection-peg hole, be to be used to draw the bus duct circuit to bypass, also be the indispensable part of bus duct.Connection-peg comprises copper bar pin 11, insulation board 10, connecting bolt 9 and nut, copper bar pin 11 1 ends are arc, the bus connection-peg hole that is used to insert on the bus duct links to each other with bus in the bus duct, the other end is a busbar joint, as the bus lead-out wire, every phase pin 11 is separated by insulation board 10, has circular hole on the insulation board 10, connecting bolt 9 passes insulation board 10 circular holes and by nut insulation board 10 and pin 11 is pushed down, and insulation board 10 is made by 95 porcelain.
The utlity model has the fireproof bus duct of fire safe type joint and connection-peg, both can in home, use and have good thermal diffusivity, can guarantee again in the environment that catches fire, to use 1.5 hours continuously.
