多路电能计量接线盒Multi-channel electric energy metering junction box

技术领域 technical field

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。 The utility model relates to a circuit wiring device, in particular to a multi-channel electric energy metering junction box.

背景技术 Background technique

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。 The electrical energy metering device currently used is connected in such a way that the secondary circuit voltage of the voltage transformer and the secondary circuit current of the current transformer are respectively connected to the electric energy meter and the load management terminal through the voltage terminal and the current terminal of the electric energy metering junction box, Connect the voltage circuits of the junction box, electric energy meter and load management terminal in parallel, and connect the current circuit in series; when replacing the electric energy meter or load management terminal with load, the secondary voltage circuit must first be opened through the voltage connection board of the electric energy metering junction box, and the electric energy The current connection board of the metering junction box short-circuits the secondary current circuit, causing the load management terminal to not measure electric energy normally when the electric energy meter is replaced, and the electric energy meter cannot measure electric energy normally when the load management terminal is replaced. The secondary circuit is disconnected and the current secondary circuit is short-circuited. The meter can only measure normally after the replacement is completed. As a result, the measurement of electric energy is not accurate enough. The power lost during the replacement process can only be recovered by estimation. The estimated results often have certain deviations from the actual ones. What's more, if the operators do not make up for the lost electricity, it will cause losses to the interests of the power supply company.

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。 As shown in Fig. 1 and Fig. 3, the voltage connecting plate 9 is disconnected, and at the same time, the third normally connected connecting terminal 12 is connected through the second current connecting plate 17 on the first upper connecting terminal 14, so that the secondary current generated in the voltage transformer The loop voltage is disconnected from the lower connection terminal 7 and the upper connection terminal 4, and the connection terminal 2 of the electric energy meter has no voltage input; at the same time, because the second current connection plate 17 on the first upper connection terminal 14 is connected to the third normally-on connection terminal 12, resulting in a short circuit between the first upper connection terminal 14 and the third normally-connecting terminal 12, the secondary loop current generated in the current transformer is input from the second normally-connecting terminal 12, and transmitted through the current connecting plate 17 To the first upper connection terminal 14, because the second upper connection terminal 15 and the first upper connection terminal 14 are connected to each other, so the current is transmitted from the second upper connection terminal 15, and enters the negative control terminal through the connection terminal 1 of the negative control terminal. terminal, and then output from the terminal 3 of the negative control terminal to the third normally connected terminal 13 of the multi-channel electric energy metering junction box, and finally return to the current transformer to form a current from the current transformer through the second normally connected terminal 12, A series current loop of the first upper connection terminal 14 , the second upper connection terminal 15 , the negative control terminal, the third normally-on connection terminal 13 and the current transformer. Therefore, when the energy meter is replaced with load, the load control terminal can measure normally.

接入两路三相三线式电能计量接线盒的电能计量装置正常运行时,带负荷更换负控终端,请参阅图4。 When the electric energy metering device connected to the two-way three-phase three-wire electric energy metering junction box is in normal operation, replace the load control terminal with load, see Figure 4.

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。 As shown in Fig. 1 and Fig. 4, the voltage connecting plate 10 is disconnected, and at the same time, the third normally connected connecting terminal 13 is connected through the third current connecting plate 18 on the first upper connecting terminal 14, so that the secondary voltage generated in the voltage transformer The loop voltage is disconnected between the lower connection terminal 8 and the upper connection terminal 5, and the connection terminal 2 of the negative control terminal has no voltage input; at the same time, since the third current connection plate 18 on the first upper connection terminal 14 is connected to the third normally connected terminal 13, causing a short circuit between the first upper connection terminal 14 and the third normally-connecting terminal 13, the secondary loop current generated in the current transformer is input from the second normally-connecting terminal 12, and passes through the current connecting plate 16, It is transmitted to the first normally connected connection terminal 11, and then input to the electric energy meter through the connection terminal 1 of the electric energy meter, and then output from the connection terminal 3 to the first upper connection terminal 14 of the two-way three-phase three-wire type electric energy metering junction box, because the first The second current connection plate 18 on the upper connection terminal 14 is connected to the third normally-on connection terminal 13 to form a loop short circuit, so the current is transmitted from the first upper connection terminal 14 to the third normally-on connection terminal through the third current connection plate 18 13. Finally, return to the current transformer to form a current from the current transformer through the second normally connected terminal 12, the first normally connected terminal 11, the electric energy meter, the first upper connected terminal 14, and the third normally connected terminal 13. And the series current loop of the current transformer. Therefore, when the load control terminal is replaced with load, the electric energy meter can measure normally.
