Abstract

A non contact power supply unit of a self-propelled trolley belongs to a power supply unit of a self-propelled trolley. The unit comprises a power transformation cabinet (1), a primary side cable (2) and an electricity picking up part (3).The power transformation cabinet (1) comprises a rectifier module (5), a filtering module (6), a high frequency inversion module (7), a frequency selection module (8), a resonant transformation module (9), an isolating module (10) and a compensation module (11); the electricity picking up part (3) includes an induction power-receiving module (12), a resonance capacitor bank (13), a resonance compensation module (14), a rectifier module (15), a filtering module (16) and a current limiting protection module (17).The power supply unit has the advantages of safe and reliable running, high reliability, and low cost and is suitable for the power supply of the self-propelled trolley in the field of automation.

Description

technical field [0001] The invention is a contactless power supply device for a self-propelled trolley (EMS). The non-contact power supply technology is used to provide the power required for the operation of the self-propelled trolley, and there is no electrical connection between the self-propelled trolley and the input power frequency power. The invention relates to the technical field of automatic transportation. Background technique [0002] The self-propelled trolley (EMS) in the field of automatic conveying technology is used to realize the automatic conveying of materials. At present, there is an electrical connection between most of the EMS and the power frequency power, and the power frequency power is transmitted to the EMS through various wiring devices such as trolley wires and cable drag chains. For linear EMS systems, power frequency power is usually delivered to the EMS by means of crawlers. For short-distance linear EMS, this method is acceptable, but onc...
