Voltage-multiplying-type high-voltage rectifying oil tank

Abstract

The invention discloses a voltage-multiplying-type high-voltage rectifying oil tank, which comprises an oil tank body, a tank cover, a high-frequency and high-voltage transformer, a filament transformer, a voltage sampling circuit, a positive end voltage multiplying and rectifying circuit and a negative end voltage multiplying and rectifying circuit, wherein the tank cover is arranged above the oil tank body and seals the oil tank body; the high-frequency and high-voltage transformer is fixedly arranged on a support below the tank cover; the filament transformer is fixedly arranged on the support below the tank cover; the voltage sampling circuit is arranged on an epoxy board and the epoxy board is fixedly connected with the support; and the positive end voltage multiplying and rectifying circuit and the negative end voltage multiplying and rectifying circuit are fixedly installed at the bottom of the tank cover with the support, and high-voltage filter capacitors are arranged in the positive end voltage multiplying and rectifying circuit and the negative end voltage multiplying and rectifying circuit. A sealing ring is arranged at the connected position of the oil tank body and the tank body in a surrounding way, an insulating plate is installed on the inner walls of the oil tank body and the entire support is isolated from the oil tank body; and a positive high-voltage socket and a negative high-voltage socket which are respectively used for outputting voltage to two bulb tubes are arranged on the top panel of the tank cover. The oil tank is used as a part of a high-frequency and high-voltage generator and is a link for high-voltage generation, the output high-voltage ripples of the oil tank are low and the quality of X-rays emitted by the bulb tubes is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a high-voltage generator for providing stable double-voltage high-voltage DC power for medical devices such as X-rays. Background technique [0002] The current single-bed single-tube high-voltage generator is basically equipped with intelligent microcomputer console, high-voltage generator, rotating anode X-ray tube assembly and tomography bed and other main components, which can be used in hospitals at all levels to combine human head, chest, abdomen, Ordinary photography and high-kV photography of limbs and bones in upright, supine, and lateral positions. The high-voltage generator provides power for the whole device, so its stability is directly related to the photographic effect, and the high-voltage rectifier oil tank is particularly critical. The ordinary high-voltage oil tank is equipped with a high-voltage transformer and a rectifier circuit to provide medical eq...
