Abstract
|
According to the theory of electromagnetic motor, a brief analysis of the induction motor’s speed are several ways to introduce the working principle of Frequency Control, in conjunction with the pumps in different methods of regulation on the use of the Frequency Control of energy-saving principles. Condensate pump for the operation and regulation of the characteristics of the way the existing problems, analysis of the condensate Pump to carry out the feasibility of transforming Frequency Control.The frequency is also a variety of methods to achieve this article focused on the technical analysis of the frequency in the middle of the DC link voltage output and methods of high-voltage Frequency of different techniques for the evaluation of the Program, and high-voltage inverter ZINVERT, for example, analyzes the Power inverter The internal structure of the unit, control unit setup to Protest.Sha Jiao A introduced a condensate pump frequency conversion transformation Power Plant equipment to choose the specific programs and condensate pump frequency after the transformation of the debugging Process, Put forward in the practical application problems that may arise and deal with the Program. Application of high-voltage inverter, after the energy-saving analysis of the situation. Test results showed that frequency electric energy-saving effects of improved significantly and can greatly improve the motor running condition, frequeney of high-voltage electric transformation programs should be Promoted.
