Household intelligent distribution box

Abstract

The invention provides a household intelligent distribution box which comprises a comprehensive load management module, a main controllable switch, detection control modules, a lightning protection module, branch controllable switches and a communication module. The lightning protection module is high in throughput and low in residual voltage, differential-mode and common-mode all-directional protection is implemented, two-level overcurrent and overheat protection is integrated in the household intelligent distribution box, the response speed of the household intelligent distribution box is in a nanosecond grade, and the response time is far shorter than 2.6 microseconds required by national standards. The household intelligent distribution box has the advantages that the problem of frequent tripping is solved for current domestic consumers, the consumers can preset protection priority of each branch, tripping of the main controllable switch during normal running of the various branches is prevented assuredly by means of turning off the branches with low priorities, main branches are effectively protected, and overall power failure is prevented; branch time-phased metering statistic and notification functions can be additionally implemented by electricity metering portions, so that the consumers are reminded of reasonably utilizing power in real time; and various interfaces for external communication bring convenience for the consumers to check information in real time.

Description

technical field [0001] The invention relates to electric power distribution box technology, in particular to a household intelligent distribution box. Background technique [0002] With the continuous improvement of people's living standards and the rapid development of industry, more and more electricity is consumed, and the electricity load is increasing. The failure of the power system is mostly caused by the failure of the low-voltage distribution line. Undoubtedly, the household power distribution system occupies a considerable proportion in low-voltage power distribution, and a safe and efficient household power distribution system plays a vital role in the safe operation of the entire power system. [0003] At present, with the increasingly prominent environmental problems, the power system is constantly being tested. The so-called embankment of a thousand miles is destroyed by ant nests, and any failure of a household power distribution system is threatening the en...

AI Technical Summary

Problems solved by technology

The lightning voltage is as high as hundreds of thousands of volts or even hundreds of millions of volts, the discharge current is from tens of thousands of amperes to hundreds of thousands of amperes, and the longest discharge duration is no more than 20ms, generally 20μs to 100μs. There is lightning in the world almost every second , Lightning accidents are also one of the extremely serious natural disasters, so it is difficult to achieve a good preventive effect only by relying on the electrical lightning protection itself
