An electric energy metering module is embedded in the G80F975 single-chip microcomputer of the unit framework.A 14-bit high-precision AD conversion module is further integrated in the G80F975 single-chip microcomputer of the framework. The G80F975 single-chip microcomputer of the framework is provided with atemperature sensor, a high-precision RTC and an IO pin. The IO pin is electrically connected with a fault indicating lamp, an operation lamp and a reset button, the G80F975 single-chip microcomputer of the framework is also internally provided with an RTC clock module, and the RTC clock module is electrically connected with an external backup battery. The intelligent low-voltage shunt monitoring unit can effectively monitor a low-voltage shunt.

Description

technical field [0001] The invention relates to the technical field of low-voltage shunt monitoring, in particular to an intelligent low-voltage shunt monitoring unit. Background technique [0002] The intelligent low-voltage shunt monitoring unit is used to monitor the reliability of low-voltage 400V user-side power consumption. With the promotion and construction of smart grids, the intelligent construction of power grids is gradually covered by high-voltage to medium- and low-voltage, especially in the past two years. The investment and construction of power grid automation and intelligence have made the intelligence of the entire power grid at voltage levels above 10kV more and more perfect. On the 400V side of the 10kV distribution transformer, effective monitoring has not yet been implemented. The intelligent low-voltage shunt monitoring unit is used for 400V low-voltage power reliability detection device, which is installed on the 400V branch lines of low-voltage dis...
