Description
The utility model relates to the power transmission and distribution device, relates in particular to a kind of fire-resistant concentration bus duct.
Existing concentration bus duct adopts the structure shown in Fig. 5 A, 5B, and it comprises one group of flat conductor 1 that be arranged in parallel, insulating barrier 2, metal shell 3 and connects termination 4 and 5.Wherein, conductor 1 is fixed in the center of metal shell 3, and it twines wrapping by the insulating tape 2 of for example polyester film, polytetrafluoroethylene, varnished glass cloth or other material, realizes each conductor 1 electric insulation each other.Connect termination 4 and 5 comprise respectively again with conductor 1 equal number be connected dististyle 41 and 51.Fig. 6 represents the connection status between above-mentioned bus duct groove and the groove.With the connection termination 5 of the connection termination 4 insertion groove B of groove A, make the dististyle 41 that respectively connects of groove A be single face contact shape, thereby corresponding dististyle 41 be electrically connected with 51 one-tenths with the dististyle 51 that respectively is connected of groove B, between the corresponding dististyle then by cross-over block 6 separations.Dististyle 41 and 51 top have groove, have two through holes (not shown) on the cushion block 6.Double insulated bolt 7 is penetrated in the groove and through hole of dististyle 41,51 and cushion block 6, and be encased inside elastic washer 8, just finished being electrically connected between groove A and the groove B behind the fastening bolt 7.
Yet, above-mentioned concentration bus duct is owing to take the refractory heat-insulating measure not yet in effectly, so around the bus duct for example during breaking out of fire, the high heat that big fire produced will be by metal shell 3 heat conduction to conductor 1, especially insulating tape 2 does great damage, not only makes bus duct not keep power supply when fire takes place, and guarantees the timely evacuation with personnel of enabling of on-the-spot fire-fighting equipment, and bus duct itself also very easily produces short circuit because of destroying, thereby results in greater loss.Therefore, in case during breaking out of fire, not only people dare not continue to use bus duct, and after the fire, also these bus ducts thoroughly must be changed, so waste is greatly.
The purpose of this utility model is to overcome existing defective in the prior art, and a kind of safe and reliable fire-resistant concentration bus duct is provided.
To achieve these goals, fire-resistant concentration bus duct of the present utility model, comprise metal shell, with metal shell all-in-one-piece frame frid is set, be arranged on one group of parallel conductor in the metal shell by the insulating barrier cladding, be installed in conductor up and down both sides, along the length direction of described bus duct be provided with at interval, in order to conductor is clamped to a plurality of cross-over blocks on the metal shell, along a plurality of fire-resistant clamping plate of the fire-resistant clamping plate and/or the left and right sides up and down of bus duct length direction setting, and two connection terminations.Wherein, each is arranged on adjacent two cross-over blocks two ends of fire-resistant clamping plate up and down, and the side end of fire-resistant clamping plate in the left and right sides and metal shell is fixed together.
According to fire-resistant concentration bus duct of the present utility model, owing to taked safe and reliable refractory heat-insulating measure, so can prevent effectively such as the destruction of adverse circumstances such as fire to bus duct.When bus duct breaking out of fire on every side,, also can not cause the destruction of electric insulation even it is for example burnt about one hour by fire.Breaking out of fire during this period of time in, it has enough ability to continue power supply, for fire-fighting equipment in the building and emergency lighting etc. provide power supply, the personnel that stamp out a fire rapidly and keep the scene intact in time evacuate, and alleviate casualties and property loss greatly.Simultaneously, after fire suppression, former fire-resistant concentration bus duct can continue to use, and need not to do thorough replacing.
Below with reference to drawings and Examples fire-resistant concentration bus duct of the present utility model is described in further detail, identical label represents to adopt identical parts in the accompanying drawing.Further purpose of the present utility model and advantage will become clearer in the following description.
