High-voltage, high-frequency and high-power transformer having a core (1) on which a primary winding (2) is disposed on which a secondary winding (4) is disposed in an insulated manner, whereupon the entire assembly is housed and mounted in an insulator (3), wherein the insulator (3) is made up of two parts or halves (6) and (7) symmetrical with respect to a transverse vertical plane, each part having a hollow tubular element (3.1) housed inside an outer housing (3.2) of each half of the insulator, defining in each part an annular space (3.3) comprised between the outer wall of the tubular element (3.1) and the inner wall of the outer housing (3.2), where the secondary or high-voltage winding is disposed, the insulator (3) presenting in its outer housing (3.2) a slot (5), which is situated at zero volts level, and though which the oil penetrates towards the secondary winding.
摘要:
Discharge module which is formed by three circuits, a control and measurement circuit for X-rays, a voltage division circuit between serial switches, which is independent from the previous one, and a third circuit of the charge short circuit, which in turn is formed by a successive or slave trip circuit of the switches and another main discharge circuit through the switches; due to the established configuration, a much improved radiation control is achieved as it is not affected by unforeseen agents, the short circuit current is not restricted to the port current of the switches, and residual voltage of the switches is reduced.

摘要:
An x-ray imaging system is provided, the system comprising an x-ray source configured to emit an x-ray beam towards an x-ray imaging detector. The x-ray imaging detector is configured to obtain an x-ray image of an object placed adjacent to the x-ray imaging detector and at least partially within a path of the x-ray beam. The system further includes a pre-exposure device positioned between said object and the x-ray source. The pre-exposure device comprises a blocking component having an arrangement of openings across an extent of the component. The pre-exposure device has an active state wherein said blocking component is configured to reside within the path of the x-ray beam, and an inactive state wherein said blocking component is configured to not reside in the path of the x-ray beam.
