Electric power collector and energy consumption monitoring method thereof

Abstract

The invention provides an electric power collector. The collector comprises a piercing power taking module and M open mutual inductor modules, wherein M is a positive integer larger than or equal to 1. The piercing power taking module is used for extracting voltage signals of a cable and is installed on a main line of a wire. The piercing power taking module is provided with a voltage output wiring terminal. The open mutual inductor modules are installed on branch lines needing signal acquisition and are provided with ground wire wiring ports and voltage input wiring terminals, wherein the ground wire wiring ports are connected with a ground wire through wires, and the voltage input wiring terminals are connected with the voltage output wiring terminal of the piercing power taking module through wires. The open mutual inductor modules are used for acquiring current signals of the measured branch lines, processing the acquired current and voltage signals and then outputting the processed current and voltage signals to an electric quantity monitoring end through communication modules arranged on the open mutual inductor modules. Electric energy monitoring can be conducted on electric equipment without power outage; besides, the electric power collector is simple in structure and can adapt to complex spot transformation environments.

Description

technical field [0001] The invention relates to the field of energy consumption monitoring, in particular to a power collector capable of completing energy consumption monitoring of end user power lines without power failure and an energy consumption monitoring method thereof. Background technique [0002] With the country's emphasis on energy conservation and emission reduction, all end users urgently need to monitor energy consumption to provide data support for emission reduction. However, in some special occasions, it is very difficult to carry out power outage reconstruction, and it is necessary to coordinate the needs of all parties, which has a great impact on the construction schedule and cost control. Therefore, a kind of energy-saving transformation method without power failure is imminent. [0003] The current transformer in the traditional system consists of a primary transformer and a secondary transformer (generally called an instrument transformer, which is i...

Problems solved by technology

However, in actual project construction, it is difficult for the owner to cut power, especially in some special occasions, such as laboratories, hospitals, airports, etc., which require 24-hour uninterrupted power supply, which will seriously affect the construction progress. increase construction cost

In addition, the volume of traditional monitoring equipment is relatively large, and the space in the substation, box-type transformer, and user station meter box is relatively small, which will adversely affect the construction operation during the energy-saving transformation process

Most of the current energy consumption monitoring equipment is a wired network, and communication cables need to be laid during the construction process, which also slows down the construction progress and increases the cost
