Abstract

The invention discloses an electrical system with a promoting protection function. The electrical system is composed of a front-end processing circuit, an amplifying circuit connected with the output end of the front-end processing circuit, a drive circuit connected with the output end of the amplifying circuit, and a fine adjustment circuit connected with the drive circuit; the electrical system is characterized in that an alarm circuit is further connected to the output end of the drive circuit, and composed of a sampling circuit and a detection circuit. The electrical system with the promoting protection function is provided with the alarm circuit, and then is capable of automatically detecting the system voltage and giving corresponding alarms by use of the alarm circuit; people can judge whether the system voltage is normal according to the alarms and perform corresponding processing to ensure that electric loads work within a normal voltage range.

Description

technical field [0001] The invention relates to an electrical system, in particular to a symmetrical voltage stabilizing and oscillating electrical system with a reminder and protection function. Background technique [0002] With the improvement of people's requirements for the quality of life, electricity is one of the core disciplines in the field of modern science and technology, and it is an indispensable key discipline in the field of high-tech today. It is the great progress of electronic technology that promotes the arrival of the information age based on computer networks and will change the way of human life and work. The current electrical system cannot detect whether the system voltage is normal. If the system voltage is too high or too low, it will affect the normal use of the terminal load. This not only affects the service life of the electric load, but also seriously affects people's production and life. Contents of the invention [0003] The purpose of t...
