The invention provides a device and technology for solving a short-circuit hazard and ensuring the circuit safety of a disinfection cabinet. According to the invention, firstly energy is taken from load current by a current transformer to establish a power supply of a control circuit, so that alternating current interference caused by establishing the control circuit by an alternating current power supply which supplies power to a load is avoided. Meanwhile, the output point of the current transformer is changed to be powered by a current source, the key change facilitates that the power supply of the control circuit is not influenced by short circuit or overcurrent of the load, and the power of the power supply is more sufficient when the load is subjected to short circuit or overcurrent,so that the short circuit and overcurrent protection is ensured to be timely and effectively controlled. When the disinfection cabinet is short-circuited, a breakpoint switch is immediately started to supply power to an alternating current switch controller, a focus-free alternating current switch is directly controlled to control the alternating current, and electric sparks are generally not generated during the switching or short circuit, so that the occurrence rate of electrical fire disasters is greatly reduced. In addition, the switch is not limited by the switching frequency and free ofmechanical wear, thereby being a super safety switch with long service life and high reliability.
Description
[0001] 1. Technical field [0002] The invention relates to the design field of disinfection cabinets, and proposes a device and technology for solving the short-circuit hazard of the disinfection cabinet 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 ...
