Meticulous line loss management equipment for 0.4 KV low-voltage transformer area

Abstract

The invention relates to the technical field of electric equipment management, in particular to meticulous line loss management equipment for a 0.4 KV low-voltage transformer area. The conventional equipment cannot calculate area line loss, has no effective means to monitor whether a meter works properly or not, and cannot effectively judge line aging, inaccuracy of measuring instruments, line overload and abnormal line loss caused by steal and leakage of electricity and the like. The equipment comprises a meter, wherein the meter is connected with a power supply bureau server through a GPRS network; an antenna is arranged above the meter, and a mutual inductor is connected with the lower part of the meter; the meter has a GPRS function. The improved meticulous line loss management equipment utilizes the mutual inductor to collect high-voltage voltage and current signals, and a multifunctional watt-hour meter metering device and a GPRS terminal are integrated, so that the meticulous line loss management equipment realizes real-time monitoring for the electricity consumption situation of public transformer users, is stable and reliable in working, and has great economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of electrical management equipment, in particular to a refined management equipment for line loss in a 0.4KV low-voltage station area. Background technique [0002] At present, there are low-voltage metering equipment in the power system. This equipment is mainly composed of multi-functional electric meters and metering boxes. It is mainly used to measure the power consumption, voltage and current of public transformer users, and at the same time as a source of data for line loss analysis in the public transformer station area. , but according to the actual usage on site, there are the following problems in the use of this device for online loss analysis: 1. At present, the multi-functional electric energy meter can only measure the user's electricity in the public transformer station area, and at the same time as the source of line loss analysis data, but it can only be calculated up to The comprehensive li...

[0002] At present, there are low-voltage metering equipment in the power system. This equipment is mainly composed of multi-functional electric meters and metering boxes. It is mainly used to measure the power consumption, voltage and current of public transformer users, and at the same time as a source of data for line loss analysis in the public transformer station area. , but according to the actual usage on site, there are the following problems in the use of this device for online loss analysis: 1. At present, the multi-functional electric energy meter can only measure the user's electricity in the public transformer station area, and at the same time as the source of line loss analysis data, but it can only be calculated up to The comprehensive line loss in the station area, but not the regional line loss; 2. Due to the multi-functional electric energy meter running for many years, there is a lack of effective maintenance, and many meters are inaccurate and abnormal, and there is no effective means to monitor whether the meters are running normally; 3 .The multi-function electric energy meter has no effective function to check whether the power consumption of the public transformer user is abnormal or whether there is electricity theft; 4. At present, it is impossible to effectively judge the abnormal line loss caused by line aging, inaccurate measuring instruments, line overload, and leakage of electricity.
