The invention belongs to the field of electric energy metering, and particularly relates to a disconnection monitoring method of a control tie line between an electric energy metering device and a breaker. The method involves the electric energy metering device, the breaker and the control tie line, the electric energy metering device is connected with the breaker through the control tie line, and a dry contact circuit, an optical coupling isolation circuit, an MCU system and a communication circuit are arranged in the electric energy measuring device. According to the disconnection monitoring method, the application situation of the control tie line of each system node of the electric energy metering device can be monitored in real time, the states of the control tie lines can be uploaded into an information monitoring center in real time, so that related personnel can respond in time, and therefore it can be guaranteed that clients can use electricity reliably in the condition of prepayment.
Description
technical field [0001] The invention belongs to the field of electric energy metering, and in particular relates to a system and method for monitoring a disconnection of an electric energy metering device. Background technique [0002] With the continuous deepening of the transformation of the national power grid, the electric energy metering device system has become more and more popular and widely used, and its ease of use has been recognized by the majority of users. For this reason, the relevant national regulations also put forward higher requirements for the use of electric energy metering devices. [0003] The existing electric energy metering device system consists of three parts: the electric energy metering device, the control tie line and the switch behind the meter. In order to prevent customers from over-consumption of electricity, when the user does not purchase electricity or the prepayment is exhausted, the electric energy metering device controls the connec...
