Description

technical field [0001] The invention relates to the technical field of pressure regulation systems, in particular to a multifunctional three-phase pressure regulation device. Background technique [0002] Three-phase voltage regulators, also known as thyristor power regulators, thyristor power regulators, or power regulators for short, are mainly used in various electric heating devices (such as electric heating industrial furnaces, electric heating dryers, electric heating oil furnaces, various The heating power adjustment of the reaction tank and the electric heating device of the reaction kettle can be adjusted manually, and can also cooperate with the electric adjustment instrument, intelligent adjustment instrument, PLC and computer control system to realize the constant value or program control of the heating temperature. Existing three-phase voltage regulators can only perform independent voltage regulation during voltage regulation and cannot be adjusted synchronousl...

AI Technical Summary

Problems solved by technology

The existing three-phase voltage regulator can only perform independent voltage regulation during voltage regulation, and cannot be adjusted synchronously. The regulation method is relatively simple and cannot meet the needs of practical applications.

[0003] In addition, with the development of the economy, a large number of users have begun to use inductive equipment such as air conditioners and induction cookers, resulting in serious reactive power loss, increasing the instability of users' electricity consumption, and unable to meet the electricity consumption of normal residents.
