Abstract

大功率同步发电机铜排引出装置,属于发电机技术领域,具体技术是:定子端部加装6个导电圆环,用于将三相绕组首末端全部引出。汇流排分两列布置,导电圆环、导电圆环和导电圆环为一列,导电圆环、导电圆环和导电圆环为一列。各导电环外圆接触面与各汇流排连接片焊接,同时各汇流排与各连接片连接处做减薄处理。各导电圆环彼此间距相同。连接6个导电圆环的汇流排上打上下各若干孔,在汇流排接中性点电流互感器时,采用下方的孔进行连接,这样既不用加高中性点电流互感器,节约了空间,也节约了材料,提高了运行的可靠性。

Description

大功率同步发电机铜排引出装置
技术领域
本实用新型属于发电机技术领域,具体是指大功率同步发电机铜排引出装置的技术。
背景技术
根据相关规定,当电机额定电流大于3000A时,不能再采用电缆引出,当电机功率大于2500KW时,必须中性点引出加装中性点电流互感器,以便监测及保护发电机可靠运行。因此,原有的引出装置就不能满足现行要求。
发明内容
本实用新型的目的是解决由于电流大,空间紧张,引起的绕组端部连接、绝缘等问题的可靠引出装置。
技术方案是:定子端部加装6个导电圆环,用于将三相绕组首末端全部引出。汇流排分两列布置,三个分别隔开的导电圆环为一列,各导电环外圆接触面与各汇流排用连接片焊接,同时各汇流排与各连接片连接处做减薄处理,各导电圆环彼此间距相同。
附图说明
图1:发电机左视图汇流排
图2:发电机主视图汇流排
具体实施方式:
定子(10)端部加装6个导电圆环,用于将三相绕组首末端全部引出。汇流排(8)分两列布置,导电圆环(1)、导电圆环(3)和导电圆环(5)为一列,导电圆环(2)、导电圆环(4)和导电圆环(6)为一列。各导电环外圆接触面与各汇流排(8)连接片(7)焊接,同时各汇流排(8)与各连接片(7)连接处做减薄处理。各导电圆环彼此间距相同。连接6个导电圆环的汇流排上打上下各若干孔(9),在汇流排接中性点电流互感器时,采用下方的孔(9)进行连接,这样既不用加高中性点电流互感器,节约了空间,也节约了材料,提高了运行的可靠性。由于采用了上述技术方案电机绕组端部长度大为减少,使得电机总长也相应缩短,降低了成本。
