摘要: A high-power four-quadrant converter system includes a double-secondary-side oil-immersed rectifier transformer with an output connected to four three-phase bridge type thyristor rectifiers, wherein every two rectifier bridges share a group of rectifier transformer secondary sides; two rectifier bridges sharing a group of rectifier transformer secondary sides are inversely connected in parallel, one of the two rectifier bridges realizes a forward output, and the other one realizes a reverse output; two groups of rectifier bridges which output in the same direction can operate independently or in parallel; when the two groups of rectifier bridges operate in parallel, reactors are connected in parallel to realize current sharing; and the rectifier bridges for the forward output and the reverse output realize free smooth transition under control of a controller, so that a four-quadrant operation of an output current is realized. When the system operates, the electromagnetic compatibility of sensitive components is high.

摘要: Disclosed is a solid lithium-lead blanket for a fusion reactor, where a solid lithium-lead alloy is adopted as a neutron multiplier and a tritium breeder, and is placed in a form of a unitary or binary pebble bed inside a structural skeleton composed of structural materials; and nuclear thermal deposition in the solid lithium-lead alloy generated due to an interaction between the solid lithium-lead alloy and a fusion neutron is moved out by a coolant. A proportion of lead atoms in the solid lithium-lead alloy is low, so that, under normal operations and accident conditions of the blanket, the solid lithium-lead alloy always remains in a solid state without melting, and tritium can be brought out of the reactor by purge gas flowing through the pebble bed to allow tritium self-sufficiency. The blanket of the present disclosure does not require beryllium to meet the requirements of tritium breeding.

摘要: The invention relates to the technical field of radar detection, in particular to a method for radiation calibration of airborne hyperspectral imaging LiDAR system. The method comprises the following steps: S1. A monochromator in a spectrum calibration system emits optical signals of different spectrum values to scan the radar system, thus to obtain the bandwidth and central wavelength of each channel in the radar system; S2.
