Integrated small intelligent power acquisition module

Abstract

Provided is an integrated compact intelligent power information collection module. The power information collection module comprises: a module base (6), a power access and voltage sampling unit (1) disposed on the module base (6), and a circuit board (4) connected to the power access and voltage sampling unit (1), wherein a test power cable (L) is clamped by the module base (6) and the power access and voltage sampling unit (1) so that the power information collection module engages the test power cable (L), and the power access and voltage sampling unit (1) pushes a pointed mechanism thereof to pierce an insulation layer of the test power cable (L) so as to sample a voltage of a conductive core (M) of the test power cable (L). The power information collection module is characterized by a compact size, a light weight and a low cost, and can be installed easily. Moreover, the invention can effectively monitor power utilization information and power quality of a power utilization loop branch, thereby realizing precise power utilization management.

Description

technical field [0001] The invention relates to an integrated small-scale intelligent power collection module, which belongs to the field of energy efficiency monitoring. Background technique [0002] In order to achieve refined power consumption management and demand-side response, and to achieve the goals of orderly power consumption, energy saving and consumption reduction, in addition to the monitoring of the total power consumption circuit, the power consumption unit also needs to expand the monitoring of each branch power consumption circuit. In the prior art, current transformers, collectors, communication modules and other equipment are generally installed in each branch circuit to realize the monitoring of power consumption information and power quality of each power consumption circuit. [0003] The current transformer in the traditional system consists of a primary transformer and a secondary transformer (generally called an instrument transformer, which is instal...

AI Technical Summary

Problems solved by technology

[0003] The current transformer in the traditional system consists of a primary transformer and a secondary transformer (generally called an instrument transformer, which is installed in the collector), which is large in size and high in cost. It is difficult to install due to the limitation of on-site installation space, and even some branch circuits Retrofitting is required for installation; there are many branch circuits in the power consumption unit, and each circuit needs to be connected to current transformers, collectors, communication modules and other equipment, and the cost of equipment is high; in addition, the collector needs to be connected to voltage signals from each branch circuit on site. Power outage operation is required during installation, which affects the production and operation activities of power consumers; there are many cables connected to the site, and even professional wiring is required, which makes installation difficult and heavy workload, high construction cost, and long construction period
