Technology for solving short-circuit hazard of residential electric wire and ensuring household power utilization safety

Abstract

The invention provides a technology for solving a short-circuit hazard of a residential electric wire and ensuring the household power utilization safety. The technology is characterized by actually comprising practical technologies in two aspects, one is a two-wire alternating current control switch technology which mainly plays a role in switching on and off, and the other is a switching circuittechnology which is used for continuously switching on and off in an alternating current circuit. The technology is formed by sequentially connecting an external power supply, a focus-free alternating current switch, a current transformer and a breakpoint switch in series. The alternating current switch controller is connected with the current transformer and the breakpoint switch in parallel ina two-wire mode. According to the technology, the output point of the current transformer is changed to be powered by a current source, so that the short circuit and overcurrent protection is ensuredto be timely and effectively controlled. When the residential electric wire is short-circuited, a breakpoint switch is immediately started to provide a power supply for the alternating current switchcontroller, the focus-free alternating current switch is directly controlled to control the alternating current, no electric spark is generated during switching, and no electric spark is generally generated at the short-circuited position when the short circuit occurs, so that the occurrence rate of electrical fire disasters is greatly reduced.

Description

[0001] 1. Technical field [0002] The invention relates to the design field of residential electric wires, and proposes a device and technology for solving the short-circuit hazard of residential electric wires and ensuring the safety of household electricity use. [0003] 2. Background technology [0004] The invention and use of electricity has brought great changes to people's production and life. The widespread use of electricity has driven lasting and profound structural changes in production. Electricity gradually replaced steam. In the 1870s, as new electricity entered the production field as a new energy source, it became the main power of factory machines, and human history entered the "Electrical Age". Due to the use of electricity, other industrial sectors have also developed rapidly, especially the development of the steel industry, which has made mankind bid farewell to the "cotton era" in the field of materials. Electrification and the advent of the "Steel Age...
