Embodiment Construction

[0016] The price of the laser light source has no obvious relationship with the power emitted by the laser, that is to say, the price difference between a light source with double power and a light source with three times power is not much different, and each light source accounts for a high proportion of the cost of the whole set of equipment. Reducing the cost of the light source will directly and greatly reduce the cost of the complete set of equipment.

[0017] In the field of optical fiber communication, couplers are used to realize the multi-channel change of optical signals and establish optical fiber networks. Inspired by this, the present invention utilizes an optical splitter and an optical combiner to split and recombine high-power energy lasers to achieve the goals of saving and reducing costs, mutual protection, and improving reliability and stability.

[0018] The present invention is illustrated by the following examples, but it does not mean that the present in...

Abstract

The invention provides a laser energy-supplying device. The device comprises a laser module and a light splitting module; the laser module is connected with the input terminal of the light splitting module by optical fiber. After the laser module outputs laser to the light splitting module, the light splitting module divides the laser into three bunches and transfers the laser to A-phase equipment, B-phase equipment and C-phase equipment respectively. The device can satisfy the requirements of power supply of three-phase load, cost is low, reliability is good, and maintenance is easy.

Description

technical field [0001] The invention relates to the field of high-voltage power supplies, in particular to a laser power supply. Background technique [0002] In recent years, high-power laser technology has developed rapidly and has been widely used in printing, medical treatment, lighting, engraving and other fields. The application of laser as an energy source is also on the rise, and digital active electronic transformers are a direction for the development of high-voltage transformer equipment. High-power (1W ~ 3W) fiber laser provides energy for the sensing device of the electronic transformer, and is one of the commonly used energy supply methods for active electronic transformers. Laser energy supply is to transmit energy through optical fiber, because the main component of optical fiber material is insulating material silicon dioxide (SiO 2 ), has excellent insulation properties, so laser energy supply is widely used in high-voltage equipment with high withstand v...
