Description

衬套单元管式电加热器
本发明涉及核电，特别涉及核电站核反应堆安全系统中的电加热器。
NPP反应堆设备的电加热器套管旨在确保从电源系统的电源板接收的电能转移到反应堆设备的电加热器。该母线包括电加热器、电耐热通信线、电流供给连接节点、接线盒。
已知使用在NPP OSHINOVKA，它使用的管状电加热器块(以下简称BTEN)"块管状电加热器"(RF专利号50639F24H，G21C，优先级25.02.2005)。该BTEN包括加热元件，带有螺纹孔的凸缘，保护壳，其通过紧固件固定到上述凸缘的螺纹孔中。
该设备的缺点是:
-在十的电流供应螺栓连接的存在；
-在电气安装时访问十个触点的复杂性。
最接近的技术本质是设备"套管单元管状电加热器"(RF专利的实用新型号61937，IPC H01F6/00(2006.01)，优先级22.06.2006)，其中电加热器组和密封端子盒之间的耐热,而且，差压补偿器被安装在密封端子盒的壳体中。该技术决定是为原型。
已知设备的缺点，作为一个原型，是:
-在十个电流供应的节点的螺栓连接的存在；
-安装(拆解)的复杂性，十电参数的控制性能；
-加热元件电流供应单元在运行期间的耐热性不足。
本发明的目的是提高BTEN在核电站运行中的可靠性。
本发明的技术结果是提供一种设备，该设备提供了便于组装和操作的BTAN，减少了安装时间和DOSSTART人员，增加了PETN的节点LIKOPODIJA的热稳定性。
技术结果是实现在汇流排单元是管状的，包含管状加热器的块，密封的终端盒，电源线到输出管状加热器的连接节点，它们被组合在一起，节点连接电线供,并且卡口连接的凹槽以倾斜型面的形式制成。可选地，卡口接头以不对称齿形缺口的形式制成。作为一种选择，不同长度的耐热密封插头连接器用于管式电加热器块。
本发明的本质是由附图解释。在图中。图1示出了管状电加热器的衬套单元的一般视图。在图中。图2示出了一个管状电加热器块。在图中。图3示出了现有的BTEN的电流供应单元(原型)。在图中。4图为十个插头连接器。在图中。图5表示卡口连接槽的形状。在图中。图6示出了卡口连接槽的非对称锯齿形缺口表面的形状。
汇流排块1包括管状的管状的管状的块体2、密封的端子盒3、连接节点4的电源线5到管状的端子6。管状电加热器5的端子6包括一个杆7和一个接触板8。用于连接
电源导线4为端子5的管状耐热气密卡口6连接插头9，该插头是管状电加热器8的接触板6。所述插脚10的卡口连接分别制成在所述管状电加热器6的主体上，所述卡口连接的凹槽11的制成在所述主体的卡口连接件9中。可选地，凹槽被制成具有非对称齿形凹口12的倾斜轮廓表面的形式。作为一种选择，耐热密封的插头连接器9分别由不同长度(不同长度的管状电加热器6组)制成。插座13由具有弹簧组件的卡口连接器9施力的触头14构成。该插座13的卡口式连接器9由耐热陶瓷插入件16绝缘于该卡口式连接器9的内部壳体15。为了确保将电源线4连接到管状电加热器6的端子5的节点的密封，施加耐热垫片17，以及帽螺母18用于密封电源线4。为了确保将插头连接器9固定在管状电加热器6上，施加弹簧19。插头连接器9的卡口部分的长度应该足以将插头连接器9的重量大体传送到管状电加热器6的主体上并且去除插头8上的不需要的机械负载-插座
为了制造这种器件，可以使用以下耐热材料：用于插头连接器9的外壳，15-钢08X18N10T，用于绝缘体16-由氧化铝制成的陶瓷，用于电流供给元件13-镍，用于电
该产品的使用情况如下。当在管状电加热器6上安装插头连接器9时，插头与插座8、13之间做出电连接。插塞9的轴向运动，通过在倾斜的异型槽面11上设置的销钉10的运动，通过卡扣作用电接触并同时与管状加热器6的密封结合，由于弹性垫片17和弹簧当使用带齿的切口12时，插头连接器9固定在管状电加热器6的任何中间位置。齿形槽口12的值被选择成这样，即一方面确保凸轮10的固定在中间位置，而另一方面在凸轮10上相当容易地沿着槽11的移动并且其与齿形槽口12的脱插头连接器7的拆解如下进行。插头连接器7向前移动，由于弹簧19的弹性，其轴向移动发生并且凸轮10从齿轮槽口12上脱开。当插头连接器9接通时，它断开。
为了便于将插头连接器7安装在管状电加热器2的块体上，采用不同长度的插头连接器。可选地，插头连接器7的长度被分成管状电加热器组。
因此，使用所提出的技术解决方案与已知设备相比，提高了可靠性和BTEN在核电站维护的过程：减少了时间，并简化了布线的加热器，增加了产品的耐温性，减少了设备运行中的人员。
