GM-2高压封闭共箱母线
 

高压大电流设备的理想选择
It is the ideal chose of HV large current

GM-2三相共箱封闭母线系统外壳采用铝合金或弱磁钢板(不锈钢)制造,内部导体为矩形、槽形母排(铜或铝),系统额定电流可达6300A,额定工作电压达35kV。该系统可广泛应用于发电机出线与变压器之间或变压器与高压配电柜之间的电流传输,也可应用于发电机交、直流励磁回路,变电所所用电引入或其它工业、民用设施的电源引线。
The frame of GM-2 three phase in common enclosure busbar is aluminum alloy or weak magnetic steel plate (stainless steel), inner shape conductor is rectangle、channel type (cooper or ally), system current can up to6300A, rated working current up to 35kV. It is widely used between outgoing of power and transformer or between transformer and HV switchgear to transmission current, it can also used in DC or AC field circuit of power, it can be used as power lead wire of electric substation or other industry, domestic facilities.

安全可靠
Safety and reliable

母线导体选用优质高强度大爬距绝缘子支撑,使系统具有较高的抗短路电动性能,合理的绝缘子支撑间距的设置,充分避免了系统共振的危险,全连续外壳并多点接地方式杜绝了人身触电危险。
Support bus bar conductor is high-grade high strength large span insulator porcelain, it can make the system has good ability of prevent short circuit, and the installation support distance of insulator porcelain avoid the danger of system resonance, all over continuative frame and multiple earthing point prevent people contact power.

温升低 Lower temperature rise

母线外壳采用铝合金或弱磁材料可避免感应涡流发热,降低其温升,同时提高了散热性能,导体接头表面采用镀锡或镀银处理,降低了接触电阻,使导体接头处拥有较小的温升,提高了导电性能。
The frame of bus bar is aluminum alloy or weak magnetic material can prevent induction eddy current heat, lowering temperature rises, and improves abstract heat ability, conductor connection face is covered with silver, it can lowering contact resistance, make the connection point has litter temperature rise, improve conducting power.

防护等级高,运行维护方便
High protection degrees, easy operation and maintain

母线外壳防护等级达IP54,可消除外界潮气、灰尘及外物引起的接地故障。在系统两端或重要部位可设置观察窗、温度警示标记或测温远程监控装置等,运行维护方便。
Protection degrees of the frame up to IP54, it cans elimination outside moisture, dust and earthing trouble because of outside objects. Watching window, temperature remind lap or long distance supervisory control device of temperature test and so on to the two point of system or important area.
