Description
Technical field
The utility model relates to the power transmission and distribution field, particularly disclosing a kind of power transmission and distribution concentration bus duct, is a kind of novel concentration bus duct that is applied to social public places such as chemical industry, metallurgy, industrial and mining enterprises and culture and sports venue, exhibition center, archives, museum, airport, station, commercial building and skyscraper.
Background technology
Defectives such as at present domestic bus duct mostly is the shell of steel greatly, has weak heat-dissipating, and volume, weight are big.The radiating effect difference directly causes the current capacity of busbar to reduce, the waste electric energy; And steel shell can't effectively be protected bus duct system and operating personnel's safety.Now existing part producer adopts aluminium shell, but does not reach ideal effect.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art, a kind of power transmission and distribution concentration bus duct is disclosed, be a kind of specious, can be high temperature resistant, have high-protection level, safe and reliable, have energy-conservation and save the novel almag shell concentration bus duct of functions such as material.
The utility model is achieved in that a kind of power transmission and distribution concentration bus duct, comprise bus-bars conductor and cell body, it is characterized in that: described cell body comprises left and right side plate and the upper and lower cover plate made from hydronalium, left and right side plate and lower cover link into an integrated entity, the upper cover plate two ends are provided with the shirt rim, and described shirt rim is provided with screw hole; Left and right side plate also is respectively equipped with screw hole, and screw hole set on the shirt rim of its position and upper cover plate is corresponding, and left and right side plate and upper and lower cover plate are formed the intensive vallecular cavity of depositing bus-bars conductor, and the upper and lower cover plate outside is provided with fin.Described bus-bars conductor is seated in the bus vallecular cavity, the polyester basement membrane of bus-bars conductor outside parcel high insulating property, and two ends are provided with the high temperature resistant silicon adhesive tape, closely arrange between bus-bars conductor, are intensive.
Concentration bus duct integral body is the cavity type structure, shell is selected the fine aluminum magnesium alloy materials for use, the almag casing frame of left and right side plate and lower cover fin once-forming, copper busbar places cavity with folded mutually layer by layer form, between every layer of copper busbar and and outer casing inner wall between by polyester basement membrane insulation and high temperature resistant silicon adhesive tape wrap insulate, closely link to each other layer by layer, with the almag upper cover plate that is provided with left and right shirt rim of last fin integral type and be connected fastening by securing member.
The beneficial effects of the utility model are: by the integral type almag shell of the utility model design, " sandwich form " press the formula structure layer by layer, the dielectric film of high insulating property has this concentration bus duct, heat dispersion is superior, and is specious; The almag skin has stronger corrosion resistance through being oxidized to silver gray; Can reach advantage that high temperature resistant, high pressure effect utilizes big several times of aluminium shell sectional area ratio phase cross-sectional area and go bail for and protect and lead body, can long-term work in the environment place below 130 ℃; Shell dual-purpose ground connection PE line, ground connection effect are desirable, more safe and reliable more; Bus duct shell almag belongs to magnetic conductive metal, so inductance value is few, and power consumption reduces with it, simultaneously, has overcome the big noise of iron shell; The aluminium shell evenly wrap in phase line around, with each mutually as far as possible near and distance equate, so reactance is identical and minimum, overcome three-phase imbalance and the bigger shortcoming of pressure drop that traditional earthing mode causes when circuit is longer; Each phase copper busbar in the bus duct, fit tightly after zinc-plated intensive among aluminum hull, have that spacing is little, reactance is little, good heat dissipation, temperature rise are low, Heat stability is good, ampacity is big, energy-saving effect is good, the material saving, the volume that takes up room is little, fully closed structural shielding grade more reaches the IP65 standard, adapts to most adverse circumstances place, can guarantee the operation that reaches safe and reliable.
