本实用新型涉及一种电路接线装置，特别是涉及一种多路电能计量接线盒。
背景技术
目前使用的电能计量装置，其接线方式是，电压互感器二次回路电压和电流互感器二次回路电流分别经过电能计量接线盒的电压接线端子和电流接线端子接入电能表和负荷管理终端，使接线盒、电能表以及负荷管理终端的电压回路并联，电流回路串联；带负荷更换电能表或负荷管理终端时，必须首先通过电能计量接线盒的电压联板把二次电压回路开路，通过电能计量接线盒的电流联板把二次电流回路短路，造成更换电能表时负荷管理终端不能正常计量电能，更换负荷管理终端时电能表也不能正常计量电能，也就是更换任一表计时需把电压二次回路断开、把电流二次回路短路才能进行，直到更换完成，正常通电后表计才能正常计量，导致电能计量不够准确，更换过程中损失的电量只能以估算的方式进行追补，而估算的结果往往与实际有一定的偏差，更有甚者，如果作业人员对损失电量不予追补，就会给供电企业利益造成损失。
实用新型内容
基于此，有必要针对电能计量不够准确的问题，提供一种多路电能计量接线盒。
一种多路电能计量接线盒，包括接线盒体，以及与所述接线盒体相对应的盒盖，接线盒体上设有电压接线板和电流接线板，所述电压接线板设有至少两个上接线端子，所述电流连接板设有第一常通连接端子、第二常通连接端子和第三常通连接端子，所述第一常通连接端子和所述第二常通连接端子之间通过 第一电流联板连接，其特征在于，所述电压接线板还设有至少互相连接的下接线端子，所述下接线端子与所述上接线端子之间分别通过电压联板连接，所述电流接线板还设有互相连接的第一上连接端子和第二上连接端子，所述第一上连接端子设有第二电流联板和第三电流联板。
本实用新型通过在电压接线板设置至少两个上接线端子，至少两个互相连接的下接线端子，所述下接线端子与所述上接线端子之间分别通过电压联板连接，构成至少两路的并联电压电路，从而达到把每相电压回路分为至少两路的多路独立输出的目的；通过在电流接线板设置第一常通连接端子、第二常通连接端子、第三常通连接端子、以及互相连接的第一上连接端子和第二上连接端子，所述第一常通连接端子和所述第二常通连接端子之间通过第一电流联板连接，所述第一上连接端子设有第二电流联板和第三电流联板，达到带负荷更换电能表期间，负控终端能正常计量，或者带负荷更换负控终端期间电能表能正常计量，使电能计量更加准确。

在其中一个实施例中，所述第一常通连接端子、第二常通连接端子、第一上连接端子、第二上连接端子以及第三常通连接端子依次排列设置在所述电流接线板上。
通过电流接线板上连接端子的不同排列位置，提供多种连接方式，便于根据接线盒体的空间位置安排接线端子。
在其中一个实施例中，所述接线盒体采用三相三线式或三相四线式。
三相制的主要优点是：在电力输送上节省导线；能产生旋转磁场，且为结构简单使用方便的异步电动机的发展和应用创造了条件；三相制不排除对单相负载的供电，因此三相交流电获得了最广泛的应用，而采用三相三线式或三相四线式的接线盒体也得到了广泛的应用。

电流互感器中产生的二次回路电流从所述第二常通连接端子12输入，通过电流联板16，形成短路，电流从第二常通连接端子12传输到第一常通连接端子11，再经电能表的接线端子1输入电能表，然后从接线端子3输出到两路三相三线式电能计量接线盒的第一上连接端子14，由于第一上连接端子14 与第二上连接端子15相互连接，电流从第二上连接端子15输出，经负控终端的接线端子1进入负控终端，然后从负控终端的接线端子3输出到两路三相三线式电能计量接线盒的第三常通连接端子13，最后回到电流互感器，形成电流从电流互感器经第二常通连接端子12、第一常通连接端子11、电能表、第一上连接端子14、第二上连接端子15、负控终端、第三常通连接端子13以及电流互感器的串联电流回路。

结合图1、图3所示，断开电压联板9，同时通过第一上连接端子14上的第二电流联板17连接第三常通连接端子12，从而电压互感器中产生的二次回路电压从下接线端子7与上接线端子4之间断开，电能表的接线端子2无电压输入；同时，由于第一上连接端子14上的第二电流联板17连接第三常通连接端子12，造成第一上连接端子14与第三常通连接端子12之间短路，电流互感器中产生的二次回路电流从所述第二常通连接端子12输入，通过电流联板17，传输到第一上连接端子14，由于第二上连接端子15与第一上连接端子14是互相连接的，所以电流从第二上连接端子15传出，经负控终端的接线端子1进入负控终端，然后从负控终端的接线端子3输出到多路电能计量接线盒的第三常通连接端子13，最后回到电流互感器，形成电流从电流互感器经第二常通连接端子12、第一上连接端子14、第二上连接端子15、负控终端、第三常通连接端子13以及电流互感器的串联电流回路。因此，当带负荷更换电能表期间，负控终端能正常计量。

结合图1、图4所示，断开电压联板10，同时通过第一上连接端子14上 的第三电流联板18连接第三常通连接端子13，从而电压互感器中产生的二次回路电压从下接线端子8与上接线端子5之间断开，负控终端的接线端子2无电压输入；同时，由于第一上连接端子14上的第三电流联板18连接第三常通连接端子13，造成第一上连接端子14与第三常通连接端子13之间短路，电流互感器中产生的二次回路电流从所述第二常通连接端子12输入，通过电流联板16，传输到第一常通连接端子11，再经电能表的接线端子1输入电能表，然后从接线端子3输出到两路三相三线式电能计量接线盒的第一上连接端子14，由于第一上连接端子14上的第二电流联板18连接第三常通连接端子13，形成回路短路，所以电流从第一上连接端子14，经第三电流联板18传输至第三常通连接端子13，最后回到电流互感器，形成电流从电流互感器经第二常通连接端子12、第一常通连接端子11、电能表、第一上连接端子14、第三常通连接端子13以及电流互感器的串联电流回路。因此，当带负荷更换负控终端期间，电能表能正常计量。
