Abstract
一种高压(站级)电涌放电器包括多个串联级且每级包含多个电匹配的低压(分配级)聚合物封装的固态电涌放电器。每级独立的电涌放电器被连接在一起并通过具有电涌放电器连到的末端的多个等角间隔分支的铸造金属装配支架(三脚架)连接到该(或每一)相邻级的各自的电涌放电器。电晕抑制环被装配在放电器顶端并且分离的电晕抑制部件被装配在中间级的分支末端。
Description
发明所属领域：
本发明涉及有关电涌放电器的改进，也称为电涌分流器，如在电源产生和分配系统中安全处理，例如由电火花引起的大气压感应电涌以及由开关操作引起的过压。
背景技术：
我们倡导引用聚合物封装的固态分配级电涌放电器，例如在GB-A-2188199中和在GB-A-2230661中公开的，我们提出象站级电涌放电器一样的多个这种分配级电涌放电器串联排列的应用。分配级电涌放电器通常具有在24到36kv数量级的电压额定值并通过象耦合GB-A-2230661中描述的串联排列的多个电匹配的这种分配级电涌放电器在一起，比数量级为120到456kv高得多的电压额定值能够被适应。
我们的串并联站级电涌放电器被设计为替代传统的陶瓷封装的站级放电器并得到广泛承认。本发明涉及串并联放电器结构的改进。
发明概要：
尽管在GB-A-2230661描述的串并联电涌放电器中相邻串联级的各个分配级电涌放电器彼此偏置，本发明提出提供成一直线贯穿串并联排列的放电器单元。而且，而在GB-A-2230661的电涌放电器中，使用了在其外围由电晕抑制环整体形成的金属装配板以互连的串并联排列的邻近级，本发明提出一种更简单及有效的排列，使用多重分支支架(三脚架)代替装配板，分支的末梢端装备电晕放电抑制表面。
本发明的上述及进一步特征特别在所附的权利要求书中提出并且将通过以下参考附图的描述很好地理解。
图面说明：
单个的附图表示出按照本发明一个示例串并联电涌放电器上(顶)端的透视图。
实施例详述：
附图中所示的串并联电涌放电器包含多个串联级I、II等(只有顶部的两个被表示出来)，每个级都由四个电匹配的电涌放电器1组成，例如它可以是GB-A-2188199中描述的那种，但是能被另外形成只要它们显示出足够的结构完整性。每级I、II等中的各个电涌放电器1耦合在一起且通过以平均角度间隔90°从中心体部分4延伸的具有多个分支3的涂覆金属支架(三脚架)2连到下一相邻级的邻接的放电器。如同所能看到的，不同级的各个电涌放电器1彼此成一行。
独立的电涌放电器1具有外部螺纹末端固定钉5，能使电涌放电器固定到支架2的分支3末端，例如在每个分支3末端提供双重及相反螺纹的锁定螺母，其能够以扳手旋转以便将相应的两个电涌放电器的相反末端拉到一起并进入与各自分支的末端的装配啮合。
在电涌放电器1的连接之后，在分支3末端的装配被铸成金属电晕抑制体6，例如它能够形成以围绕的连接至各自分支的两个电涌放电器1的末端紧密适应的在分支3末端上的推进配合。抑制体6的表面是如图示的平滑弯曲以避免引起过大的场电压，象可能引起电晕放电效应。
在串并联排列的顶端，电晕抑制排列包括并行的空间分离的环7和8，通过装配支架9被耦合到最顶部装配支架2的分支3。
所示串并联电涌放电器相信可以满足电气需要以及装配支架和它们的零件，即电晕抑制体6和放电器固定螺母(未示出)能够以比GB-A-2230661中描述的串并联电涌放电器的静电装配板更低的成本制造。而且，由于相邻级电涌放电器成一线连接，串并联电涌放电器的整个强度与GB-A-2230661的相比提高了。另外所示电涌放电器得到了GB-A-2230661中所描述的所有优点。在不脱离所附的权利要求书中提出的发明的精神范围的情况下，各种修改和改变当然是可能的；例如，支架2能够具有比所示四个分支更多或更少的分支。
