Description

TECHNICAL FIELD

[0002] Nowadays, high-voltage and low-voltage electric energy metering devices include electric energy meters, voltage transformers, current transformers, and secondary circuits connected among the three. In order to replace electric energy meters and facilitate on-site calibration, a joint terminal box must also be connected in the secondary circuit. In recent years, with the development of science and technology and changes in policy, many factors have led to the need for replacement of electric energy meters by State Grid Corporation in power supply and distribution businesses.

[0003] First, due to differences in suppliers, types, and batches of electric energy meters, their service life varies, and in order to ensure the accuracy, reliability, and uniformity of electric energy metering and protect the interests of both power supply and power consumption parties, regular replacement is required. Second, the demand for electricity from various industries is increasing, and the phenomenon of uneven power consumption is becoming increasingly serious. Third, electric energy meters that cannot operate normally or measure accurately due to malfunctions or other reasons also need to be replaced in a timely manner.

[0004] The usual replacement method includes power-off replacement and live replacement. Power-off replacement directly affects normal power consumption by customers, resulting in poor user experience and complaints. Live replacement is more commonly used in engineering practice, especially when replacing electric energy metering devices. By introducing a joint terminal box, live replacement is achieved.

[0005] Currently, when replacing an electric energy meter, the joint terminal box is used to disconnect the voltage connection piece and short-circuit the current connection piece, thereby isolating the electric energy meter from the metering secondary circuit to achieve the purpose of replacing the electric energy meter without interruption. However, this method cannot continuously measure electric energy during the replacement of the electric energy meter, resulting in a lack of measurement during the replacement period and a loss of electric energy. Therefore, the lost electric energy needs to be calculated based on the power values before and after replacement and the electric energy needs to be recovered. This process requires accurate measurement of the replacement time period and recording of the power values before and after replacement, which is not accurate in actual operation and can easily lead to measurement disputes. Even if the customer confirms, the process of recovering the lost electric energy is time-consuming, which reduces work efficiency and affects the user's perception of good power consumption. In addition, during the replacement of the electric energy meter, incorrect connections, loose voltage or current connection pieces, and other abnormal situations such as failure to open the current connection piece after replacement can occur, resulting in inaccurate measurement and safety accidents.
