Abstract
The utility model relates to an intensive bus duct which includes an aluminium alloy profile, a silica gel, and a duct body. The outside of the duct body is provided with a housing part which is composed of the aluminium alloy profile. An inner layer of the aluminium alloy profile is provided with an insulating film. The inside of the duct body is evenly provided with a plurality of copper bars, and the silica gel is filled between each two copper bars. The beneficial effects are that through arranging the aluminium alloy housing protection and an insulating layer, the intensive bus duct has excellent dust-proof performance and water-proof performance, thus satisfying the requirements of different service environments; an insulating part adopts a flame retardant and high temperature resistant insulating material, the withstand voltage is above 3.75KV, so the security of the bus duct is greatly improved; the intensive bus duct is beneficial to realize the intelligent temperature measurement control system monitoring, thus guaranteeing the safe running of the bus duct in a normal temperature rise.
Description
Technical field
The utility model relates to the electrical power trans mission/distribution system technology, relates in particular to a kind of concentration bus duct.
Background technology
Bus is meant the connection of voltage power distribution equipments at different levels in power transformation; And being connected of electric equipment such as transformer and corresponding power distribution equipment; In electric power system, bus links together each current-carrying duplexure in the power distribution equipment, plays a part to compile, distributes and transmit electric energy.Existing common concentration bus duct is generally by metal shell, insulating cell, heterogeneous bus-bars conductor and coated insulation layer; Its metal shell is generally steel or aluminum; Required precision height in process and assemble hole around this class formation, the technology of processing can not guarantee, causes production efficiency low; Secondly, bus duct is limited use system under the relative rugged environments of condition such as needs are dustproof, moistureproof, anticorrosion, and sealing reliability can not guarantee, has also reduced the thermal diffusivity and the current capacity of bus, makes bus duct reduction in useful life.In addition, existing similar bus duct can't be guaranteed safe operation under normal temperature rise.Therefore, need reasonably improve prior art.
The utility model content
To above defective, the utility model provides a kind of dustproof and waterproof excellent performance, can satisfy different environment for use requirements, can greatly improve the security performance of bus duct, stable concentration bus duct, to solve many deficiencies of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of concentration bus duct comprises aluminium alloy extrusions, silica gel, cell body, the housing parts that said cell body outer setting is made up of aluminium alloy extrusions, and the aluminium alloy extrusions internal layer is provided with dielectric film; The some copper bars of the inner evenly installation of said cell body are filled with silica gel between per two copper bars.
The beneficial effect of the described concentration bus duct of the utility model is: through aluminum alloy casing protection and insulating barrier are set, can make it possess excellent dustproof and waterproof performance, can satisfy different environment for use requirements; Insulated part wherein adopts flame retardant type, high-temperature insulation material, more than the withstand voltage 3.75KV, has greatly improved the security performance of bus duct; Help realizing the monitoring of intelligent temperature measurement control system, thereby guaranteed bus duct safe operation under normal temperature rise.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the said concentration bus duct of the utility model embodiment.
Among the figure:
1, aluminium alloy extrusions; 2, silica gel; 3, copper bar; 4, dielectric film; 5, cell body.
Embodiment
As shown in Figure 1; The described concentration bus duct of the utility model embodiment; Comprise aluminium alloy extrusions 1, silica gel 2, cell body 5, the housing parts that said cell body 5 outer setting are made up of aluminium alloy extrusions 1, the some copper bars 3 of said cell body 5 inner evenly installations; Between each copper bar 3, be filled with silica gel 2, said aluminium alloy extrusions 1 internal layer is provided with dielectric film 4; In addition, also can be provided with total line traffic control, adopt the monitoring of intelligent temperature measurement control system, when bus duct surpasses the permission temperature rise (generally getting 55K), the temperature detection monitoring system can point out and report to the police, and notifies the operator on duty to take measures areput; The timely and effective reduction and when overstepping the extreme limit temperature rise (generally getting 60K) if temperature rise is failed, supervisory control system is sent fault-signal, cuts off the master switch power supply automatically, thereby has guaranteed bus duct safe operation under normal temperature rise.Product adopts high-quality electric conducting material (aluminium alloy extrusions) to make the bus duct shell, and shell integral body is as earth bus, resistance＜0.00001 Ω, cross section >=50% phase conductor; Be good earthing conductor, because shell earth connection as a whole, earth connection is positioned as close to three-phase bus, has accomplished that reactance is minimum; The fault current of induction is just big more, when earth fault takes place, can in time feed back fault-signal; In prescribed limit internal cutting off fault loop, safeguards system, equipment and personal safety; Owing to adopted shell to make earth connection, protective circuit continuity resistance has been accomplished minimum simultaneously, even when earth fault takes place, human body touches shell, also can not produce contact danger, has therefore improved the safe running performance of bus duct widely.
Above embodiment is more preferably embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection range of the utility model.
