適用范圍

Applicable scope

母線槽可為交流三相線、三相四線、三相五線，頻率50Hz(或60Hz)額定工作電壓660V，額定工作電流為100-5000A，產品具有體積小，輸送電流大，安全可靠，安裝靈活配電施工互不干擾，設計合理，規格齊全等優點。是現代大、中型企業高層建筑引進工程實驗基地等場所最理想的供配設備。帶插口的母線槽，可通過插接開關箱能很方便地引出電源分路。母線槽的安裝可直接從變壓器接到配電柜，也可以從低壓柜直接接到配電系統作為配電干線路。CMC密集耐火母線槽、BMC空氣耐火母線槽產品主要適用于化工、冶金、文化、體育場館、展覽館、博物館、機場、車站等社會公共場所及高層建筑的輸配電及消防系統的共用。在正常情況下（非火災情況）可降容供電：火災情況下，切斷正常供電系統，按額定電流進行消防供電，從而達到正常、消防供電兩者兼用，降低成本。

Bus duct can be divided into AC three-phase line, three-phase four-wire, three-phase five-line, with 50Hz (or 6Hz) rated working voltage 660V, rated working current 100-5000A. The product has such advantages as small size, large transport current, safety and reliability, flexible installation, no interference with power distribution and construction, reasonable design and complete specifications, etc., which is the most desirable power supply and distribution equipment to introduce engineering experimental base and other sites for high-rise buildings of modern large and medium-sized enterprises. The installation of bus duct can be directly connected to power distribution cabinet from the transformer, and also can be connected to power distribution system from the low voltage cabinet to function as power distribution main line circuit. CMC intensive fireproof bus duct and BMC air fireproof bus duct products are mainly applicable to the power transmission and distribution and common use of fire-extinguishing system in chemical industry, metallurgy, culture, stadiums and gymnasiums, exhibition halls, museums, airports, stations and other social public places and high-rise buildings. Under normal circumstance (non-fire conditions), it can reduce capacity to supply power: in case of fire, cut off the normal power supply system, and fire protection and power supply should be conducted according to the rated current to achieve the combination of both normal and fire protection power supply, and reduce the cost.
