The invention provides a device and technology for solving a short-circuit hazard and ensuring the circuit safety of an electric hot pot. 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 circuit technology whichis used for continuously switching on and off in an alternating current circuit. Firstly, energy is taken from load current by a current transformer to establish a power supply of a control circuit,a breakpoint switch is immediately started to provide a power supply for an alternating current switch controller when the electric hot pot is short-circuited, a focus-free alternating current switchis 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 shortcircuit occurs, so that the occurrence rate of electrical fire disasters is greatly reduced. Alternating current interference caused by an alternating current power supply is avoided. The key change facilitates that the power supply of the control circuit is not influenced by short circuit or overcurrent of a load, so that the short circuit and overcurrent protection is ensured to be timely and effectively controlled when the electric hot pot is short-circuited.
Description
[0001] 1. Technical field [0002] The invention relates to the design field of an electric hot pot, and proposes a device and technology for solving the short-circuit hazard of the electric hot pot and ensuring the safety of its circuit. [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" marked the rise of modern...
