Abstract

The invention provides a high-voltage generator and X-ray equipment. The high-voltage generator comprises a diode array, a shielding device and a grid-control power supply. And the shielding devices and the diode array are arranged at intervals. The projection of the shielding device in the first direction at least partially covers the diode array. And the grid-control power supply and the shielding device are arranged at an interval. And the grid-control power supply is electrically connected with the diode array. And the shielding device is arranged between the diode array and the grid-control power supply. According to the application, the parasitic capacitance between the diode array and the grid-control power supply can be reduced through the shielding device, and the parasitic capacitance of the diode array to the shielding device is increased, so that the diode array can be effectively protected during ignition, and the diode array is prevented from being damaged due to sudden voltage change generated during ignition.

Description

technical field [0001] The application relates to the technical field of medical equipment, in particular to high-voltage generators and X-ray equipment. Background technique [0002] X-ray equipment, commonly known as "X-ray machine", is a device used to generate X-rays. The main purpose of X-ray equipment is to detect the internal structure without destroying the object, and X-ray equipment has been widely used in the medical field today. The high voltage generator is one of the main components in the X-ray equipment. The high-voltage generator provides high voltage for the X-ray tube, and at the same time provides the filament heating voltage for the X-ray tube. [0003] A high-voltage generator usually includes two boxes, an inverter box and a high-pressure fuel tank, where the high-pressure fuel tank mainly includes a rectifier unit, an ignition suppression unit and a gate control unit. Wherein, the gate control unit is provided with a metal casing, and the potential...
