Abstract
An integrated minitype X-ray generator with long service life comprises an X-ray tube (1) and a high-voltage generator (2). In the integrated minitype X-ray generator with a long service life, the X-ray tube and the high-voltage generator are directly connected and then insulated and encapsulated as a whole. Since the X-ray tube and the high-voltage generator are encapsulated as a whole, high voltage cables of intermediate connection are saved so as to preclude the possibility of failure caused by the poor connection of the high voltage cables, thus improving the reliability of the whole X-ray generator. Meanwhile, due to the integrated encapsulation of the X-ray tube and the high-voltage generator, encapsulation material can be utilized for improving the insulation strength of the X-ray generator and reducing the encapsulation cost at the same time. The integrated minitype X-ray generator with long service life is internally provided with a feedback control circuit which is used for controlling the filament voltage of the X-ray tube by the working current feedback of the X-ray generator, thus causing the filaments of the X-ray tube to be in a warm-up state when not in operation.
Description
Technical field
The present invention relates to a kind of integrated x ray generator, especially a kind of x ray generator with specific package structure and special powering mode.
Background technology
Existing x ray generator generally is made up of X-ray pipe, high pressure generator and high-tension cable, and wherein X-ray pipe and high pressure generator are independent insulation-encapsulated separately.As shown in Figure 1, number of patent application is that 91110651.0 patent documentation discloses a kind of generation X-ray apparatus, it comprises is equipped with the high pressure generator (100) that is used to increase the supply voltage element, one under the high pressure effect of high pressure generator, produce the X-ray tube (1) of X ray; Connect high pressure generator and X-ray tube, high pressure is transferred to the high-tension cable (2) of X-ray tube from high pressure generator.
The major defect of this kind x ray generator is: owing to be to connect by high voltage cable between X-ray pipe and the high pressure generator, the dielectric strength that they can reach can be lower, connection formedness between them is very big to the reliability effect of x ray generator, has also increased the insulation-encapsulated cost.In addition, X-ray pipe high voltage source wherein claims high pressure generator again, it is the critical component of X-ray machine, it is a kind of relatively more accurate high voltage source, it can be divided into high voltage source and filament supply two parts, and wherein filament supply is used to the filament heating of X-ray pipe, so the filament of X-ray pipe is when each start, be subjected to rush of current owing to cold-state resistance is little, shortened the useful life of X-ray pipe greatly.
Summary of the invention
The object of the present invention is to provide the mode of operation of the filament of a kind of packing forms of brand-new x ray generator and X-ray pipe.This x ray generator can improve greatly that the dielectric strength that existing x ray generator exists is low, reliability is low and problem such as burn-out life is short.
The present invention is achieved through the following technical solutions: a kind of integrated miniature X ray generator with long life, comprise X-ray pipe (1) and high pressure generator (2), described integrated miniature X ray generator with long life the X-ray pipe with after high pressure generator directly is connected together insulation-encapsulated be one.Because X-ray pipe and high pressure generator are packaged together, and have omitted the high voltage cable of middle connection, have also just eliminated the possibility that produces fault because of the bad connection of high voltage cable, thereby improved the x ray generator whole reliability.Simultaneously,, can utilize encapsulating material to improve the dielectric strength of x ray generator, also reduce packaging cost simultaneously because X-ray pipe and high pressure generator are the one encapsulation.
Be provided with feedback control circuit in the described integrated miniature X ray generator with long life, the operating current by x ray generator feeds back the filament voltage of controlling the X-ray pipe, makes the filament of X-ray pipe be in preheat mode when not working.
The principle of described feedback control circuit is: after powering on, when not working, the operating current of x ray generator feedback is output as negative voltage, because the existence of D1, this moment, U1A can regard inoperative as; The operating voltage of x ray generator is output as positive voltage, because the existence of D3, D4, the output voltage of U1B is clamped at a fixing level, utilize this fixed level to go to control the adjusting of X-ray spot filament voltage, make it be in a kind of preheat mode of little electric current, when operate as normal, the operating voltage of x ray generator is output as negative voltage, because the existence of D2, this moment, U1B can regard inoperative as, this moment, the adjusting of X-ray spot filament voltage went to control by U1A, made the operating current of x ray generator reach predefined value.
Beneficial effect of the present invention is:
1, x ray generator of the present invention is compared with conventional x ray generator, removed the connection high voltage cable between X-ray pipe and the high pressure generator, be packaged as a whole simultaneously, improved the connection between X-ray pipe and the high pressure generator, improve reliability and dielectric strength, prolonged the useful life of X-ray pipe effectively.
2, improved the mode of operation of X-ray spot silk, the filament of X-ray pipe is in preheat mode always, has avoided the rush of current in each when start, has prolonged the life-span of filament.
3, among the present invention, X-ray pipe and the encapsulation of high pressure generator one have reduced packaging cost.And install and keep in repair all more convenient, easy and simple to handle reliable.
