[CN 201720312055.5] Capacitor energy storage device for servo press
[CN 201720312055.5] Title of a Capacitive Energy Storage Device for Servo Presses: Application Number of a Capacitive Energy Storage Device for Servo Presses: CN 201720312055.5 Applicant: Industrial Technology Research Institute of Guangdong Huazhong University of Science and Technology; Dongguan Huake Jinglong Forming Equipment Technology Co., Ltd. Application Date: March 28, 2017 Patent Type: Utility Model A Capacitive Energy Storage Device for Servo Presses, Including Power Supply Cabinet, Control Cabinet and Capacitance Cabinet, the power cabinet includes a cabinet body and a main power switch, a charging current sensor and an anti-reverse diode sequentially connected through a line in the cabinet body. The main power switch is provided with a power input terminal connected to a current bus. The capacitor cabinet includes a cabinet body and several groups of capacitor banks installed in the cabinet body. Each group of capacitor banks is composed of two super capacitors connected in series. The capacitor banks are connected in parallel with the anti-reverse diode through the line; the control cabinet includes a cabinet body and a control power switch, a fan switch, a user communication module, a voltage regulator and an output terminal installed in the cabinet body. The output terminal is connected with the driver of the servo press, and the control power switch is connected with the capacitor bank output terminal in the capacitor cabinet through a line. The utility model solves the problem of the recovery of the speed regulation energy of the motor of the large-capacity servo press and the instantaneous energy release.
