Problems solved by technology
In the 50KVA-100KVA user or transformer station area, due to the imperfect power purchase function of the GPRS network meter, the arrears alarm information is not obvious when the electricity is purchased, and it is only displayed through the alarm light on the GPRS network meter, which is difficult for the user to detect Unable to know the power consumption and remaining power situation in time, and miss the power purchase time, resulting in unprepared trip
After the trip, the user does not know the cause of the trip, whether it is an arrears trip or a fault trip, and cannot resume power transmission in time, which affects the normal production of users and the electricity sales of the power system
In addition, when someone opens the meter box, there is no alarm function, which poses a safety hazard

The invention relates to an intelligent terminal box of a GPRS (General Packet Radio Service) network list, which is used for user side management, electricity purchase management, switch monitoring, incident report and inner manager checking, has a warning function, can ensure the safe and reliable operation of a metering device and prevent the occurrence of electricity stealing incidents. An isolating switch, a metering current transformer and the GPRS network list are installed in a metering unit, and a load switch is installed in a user switch unit. The intelligent terminal box is characterized in that an intelligent controlled warning device is installed in the metering unit, the intelligent controlled warning device is connected with the GPRS network list through a data line for bidirectional communication, an access control switch is arranged in the metering unit and is connected with the intelligent controlled warning device and the GPRS network list, an isolating baffle plate is installed in the user switch unit and locked through a sealed lock, and a tripping recognizing device which is connected with the intelligent controlled warning device is arranged on the load switch, is used for prompting a tripping type for a user and carrying out acousto-optical warning for various abnormal states, and can be applied to the users of 315KVA and below.
Description
technical field [0001] The invention relates to an electric energy metering device, in particular to a GPRS network meter intelligent terminal box. Background technique [0002] The traditional meter box is composed of a metering current transformer and an electric energy meter, which can only realize electric energy metering. The GPRS network meter is a network energy meter that has appeared in recent years, and has the functions of remote meter reading and pre-purchasing electricity. In the 50KVA-100KVA user or transformer station area, due to the imperfect power purchase function of the GPRS network meter, the arrears alarm information is not obvious when the electricity is purchased, and it is only displayed through the alarm light on the GPRS network meter, which is difficult for the user to detect Failure to keep abreast of power consumption and remaining power conditions, missing power purchase time, resulting in unprepared trips. After the trip, the user does not k...
