Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects of the above-mentioned existing refrigerator design, and provide a method to solve the safety problems such as electric shock casualties and fires caused by the surge current generated when the wires of the refrigerator are short-circuited, so as to solve the short-circuit hazard of the refrigerator and ensure its safety. The circuit is safe, and the refrigerator can continue to work normally through the two wires at the other end when a short circuit occurs

Abstract

The invention provides a device and technology for solving a short circuit of a refrigerator while maintaining the normal operation. By means of random access of a four-wire refrigerator alternating current control switch, a focus-free alternating current switch of a photoelectric coupling assembly comprising a light emitting device and a photoconductive device can be connected as long as a breakpoint is made at any position of alternating current, and the transmission of on-off control signals to each controlled power-off switch in an optical isolation mode needs to be completed through at least one photoelectric coupling assembly. Energy is taken from load current by a current transformer to establish a power supply of a control circuit. The refrigerator alternating current four-wire solid-state switch has a particularly excellent short-circuit protection function, namely, surge-free short-circuit protection, electric sparks are generally not generated at the short-circuited positionwhen loads are all short-circuited, and no damage is caused to the power supply, the wire, the switch and the like. The switch is externally provided with four leads, and when two of the leads are short-circuited, the other two leads are switched to enable the refrigerator to continue to operate normally.

Description

[0001] 1. Technical field [0002] The invention relates to the design field of refrigerators, and proposes a device and technology for solving the short circuit of the refrigerator and still working normally. [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 industry. The electric powe...
