带有接地刀闸的农网配变总表箱
摘要：
本实用新型涉及一种带有接地刀闸的农网配变总表箱。包括总表箱本体，其特点是：在所述总表箱本体内安装有刀闸（K），该刀闸（K）的进线端分别与零线端子和三相火线端子连接，而该刀闸（K）的出线端均接地。经过试用证明，采用本实用新型的总表箱后，彻底解决了传统的低压0.4KV短路作业时，从接地线领取、现场展放、挂接及拆除费时费力、效率低下的问题，解决了在挂设配变总表箱内接地线时，由于箱内刀闸、断路器相间间隙过小及空间受限，接地线往往不能够可靠与之连接，存在安全隐患的问题。采用本实用新型后，减少了低压接地线的使用，从而减少了领取、回收的工作量。
摘要（英）：

The utility model relates to a rural power grid distribution and transformation total meter box with a grounding disconnecting link. The total meter box comprises a total meter box body. The total meter box is characterized in that a disconnecting link (K) is installed in the total meter box body; an incoming line terminal of the disconnecting link (K) is connected with a zero terminal and a three-phase live wire terminal respectively; outgoing line terminals of the disconnecting link (K) are grounded. After the total meter box of the utility model is used, problems that time-consuming and labor consuming are achieved and efficiency is low during grounding wire receiving, on-site displaying, hitching and removing when a traditional lower voltage 0.4KV short circuit works are solved; a problem that the grounding wire can not be reliably connected and a potential safety hazard exists because a gap between the disconnecting link in the box and a circuit breaker is too small and a space is limited when the grounding wire in the distribution and transformation total meter box is hanged is solved too. After the total meter box of the utility model is used, usage of the low voltage grounding wire is reduced so that workload of receiving and recycling is decreased.
