Intelligent temperature control device of mold pressing platform variable-frequency power source

Abstract

An intelligent temperature control device of a mold pressing platform variable-frequency power source belongs to the technical field of manufacturing of motors. The temperature control device comprises a power supply device and a temperature measurement circuit. The power supply device comprises a three-phase five-line power source input end, a three-phase circuit breaker, a rectifying device, an inverting device, an isolated transformer, and a protection drive circuit, wherein the rectifying device is an AC / DC converter; the inverting device is a DC / AC converter; the isolated transformer has a voltage-reducing current-rising function; the output terminal of the isolated transformer is connected with a measurement display circuit; the protection drive circuit is connected with the control terminal of the rectifying device and the drive terminal of the inverting device; and the protection drive circuit, the measurement display circuit, and the temperature measurement circuit are connected with comprehensive display control equipment. The intelligent temperature control device of the mold pressing platform variable-frequency power source not only can solve the problem in the prior art that single-phase power sources are unbalanced, but also can increase the power source efficiency and the power factor while simultaneously realizing the automatic voltage regulation and solving the problem that the control precision is low under hand-operated voltage regulation conditions.

Description

technical field [0001] An intelligent temperature control device for a variable frequency power supply of a molding table belongs to the technical field of motor manufacturing, and in particular relates to a temperature control device for controlling heating and shaping of motor wire rods. Background technique [0002] According to the available information and purchased products, the power supply unit of the molding table adopts a saturated reactor for voltage regulation. This voltage regulation method has the disadvantages of low power supply efficiency and power factor. In addition, due to the use of single-phase AC power supply, the power grid of the factory is seriously unbalanced, and the power supply system often trips due to excessive current in one phase, which affects normal production. In addition, all pressure regulation controls are manually operated by operators based on experience, and due to differences in subjective judgments, the control accuracy is low. ...
