Problems solved by technology

However, due to the limited capacity of the battery carried by the meter itself, as time goes by, its battery power is in a state of loss, resulting in power loss of the meter, and the power consumption information collection system cannot collect user site data remotely, forming a blind spot in load side management

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0014] A system that solves the problem of high-voltage meters being powered off and unable to communicate remotely, such as figure 1 As shown, it includes a 230MHz collection terminal, a collection terminal power supply and an electric energy meter. The electric energy meter includes a terminal electric energy meter I and a power supply auxiliary terminal smart meter II. Both ends of the 230MHz collection terminal are connected to the collection terminal power supply. The terminal power supply is divided into three routes, one route is used for the terminal electric energy meter, and the other two routes are used for the auxiliary terminal smart meter of the power supply.

[0015] The smart meter of...

Abstract

The invention relates to a system overcoming incapability of remote collection of a high-voltage meter during power losing. The system is scientific and reasonable in design and simple in structure. Three paths are led out of a power supply of a collection terminal, one path is led to a terminal electric energy meter, the other two paths are led to a power supply auxiliary terminal intelligent meter, and thus the intelligent electric energy meter is parallel with the power supply auxiliary terminal intelligent meter, resources are saved effectively, and the construction safety is ensured. A fault of an onsite meter can be discovered timely in the using process, the full-life period management level of the metering equipment is improved, convenience is provided for recovering of electricitycharge, electric quantity is made up timely, solid basis is provided for line loss analysis of high voltage users, the power utilization information collection success rate of the high voltage usersis improved by 2 percentage, the load-side management level is improved, a remote collection blind area is made up timely, the onsite maintenance cost is reduced, and more than millions of electricitycharge loss can be taken back for the company.

Description

technical field [0001] The invention belongs to the technical field of marketing metering, relates to on-site metering technology for high-voltage users, in particular to a system that solves the problem of high-voltage meters failing to communicate remotely due to power failure. Background technique [0002] At present, users of high-voltage dual power supplies, due to the nature of their application load, are often operating with a single power supply and the other power supply is in a cold standby state. When the power supply of the user's I line is running and the II line is out of service for a long time, or when the user is performing equipment maintenance, a reverse circuit occurs, the I power is cut off, and the II line is running. As a result, one of the power meters is out of service. At the beginning of the design of the user's power consumption scheme, each of the two power sources has a set of meters to measure its power consumption. However, due to the limite...
