Micro-meter for electrical energy consumption

摘要

This invention is an encapsulated Micro-Meter-Manager for Electrical Energy Consumption (1), including: A current ring transformer +Voltage pickup on each wire by spikes which traverse the insulation of the wire as far as its metallic core or by screwed terminals +Miniaturized power supply source +Microprocessor/s +Button cell +Digital memory +Clock +Power Line Communication PLC Modem, which injects the data into the actual wire via the same spikes for the pickup of voltage or terminals +Solid state relay (SSR) for individually managing the actual load: From a ceiling light to a water heater or any industrial machine. Its aim is to provide own intelligence on the loads and to avoid undesired consumptions: controlling the stand-by, carrying out predictive maintenance according to its rated consumptions and managing any possible overloads, under a certain pre-established and reprogrammable logic. With this, an increase in the comfort and the safety of the entire installation is also achieved.

主权项

1. A micro-meter for electrical energy consumption, encapsulated and miniaturized for its easy fitting on actual supply wires, both in the head of electrical installations and in the interior of domestic appliances, lamps or any kind of machine; wherein the main components of each unipolar unit (one to three for the phases and one for neutral) of the version for single/three phase installation comprise:
a hinged casing (1.1); a split core current transformer for measuring current circulating through a conductor; a voltage transformer; a plurality of spikes protruding from an inner surface of the hinged casing, able to pierce into a metallic core of the conductor, via an insulation of the wire, for pickup of voltage and injection and reception of coded signals by means of PLC (Power Line Communication) technology (1.2); a Power Line Communication PLC Modem (11) which injects and receives data from the actual wire of the electrical network; a miniaturized power supply source; a microprocessor, a button cell, a digital memory and a clock; a solid state relay (SSR) or other technologies for connection/disconnection of a load in a manager model of the micro-meter; and an earth connection.
