Abstract

The invention comprises multi rectification boxes; each rectification box shapes cuboid, and has a shielding cover on its external surface; the rectification boxes are attached together through link connection, and on all identical end faces of them, the securing plates are respectively installed; on the both end of each securing plate a discharge ball is respectively mounted; a gap is kept between two discharge balls respectively located on the two neighboring plate; the end faces of the rectification boxes opposite to the discharge balls there are shielding plates installed; the shielding plates are secured on the corresponding rectification box, the other end of each rectification box extends out to same direction and is overlapped with other shielding plates on the rectification boxes.

Description

Section type rectifier for electronic accelerator

Technical field

The present invention relates to a kind of rectifying device.Be the section type rectifier on the high-frequency electronic accelerator specifically.

Background technology

Know all that in the electron accelerator manufacturing high frequency power of high frequency high voltage electron accelerator is transported to respectively on each rectifier by coupling capacitance, behind over commutation, just have direct current to flow through.Because each rectifier is chained together, and can produce bigger voltage drop, thereby make accelerator obtain high pressure.Therefore, rectifier is the core component that produces dc high-voltage.

Hf rectifier wherein all is traditional rectifier, and this conventional rectifier all is to adopt the integral cast structure.Owing to adopt the integral cast structure, in case break down, be difficult to find the fault point, repair very difficulty.In addition, two-layer housing is contained in the inside of this rectifier, and can the account for limited inner space of rectifier of two-layer housing makes that devices such as diode that this rectifier holds and electric capacity are less, and therefore, the rectification effect of this rectifier is bad.Again on the one hand, because rectifier is operated in the high electric field environment, if adopt the integral type cast structure, its surface has the convex-concave point unavoidably, and the convex-concave point is easy to cause point discharge.Therefore, casting process is had relatively high expectations.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of section type rectifier for electronic accelerator.This section type rectifier for electronic accelerator, maintenance easily, rectification effect is good, and is not high to manufacture process requirement.

For addressing the above problem, take following technical scheme:

Characteristics of the present invention are to contain several rectification boxes, and this rectification box is a cuboid, and there is housing its outside, and they link together by connecting rod each other, on their the same end face fixed head are arranged all.Said fixed head arranges that along the closure of rectification box their two ends all are upturned and ball discharge is installed.Leave the gap between the ball discharge on two adjacent fixed head neighboring terminals.On the rectification box end face relative with ball discharge is installed barricade is arranged all, an end of these barricades is fixed on the corresponding rectification box, their other end all to same direction stretch out and and adjacent rectification box on barricade between be the gap-like overlaid.

Take such scheme, have the following advantages:

Because the present invention contains several rectification boxes, adopts a plurality of rectifiers to link together, and carries out the segmentation rectification.One measures existing fault, finds the fault point easily, repairs than being easier to.Because barricade is installed on the end face of rectification box, can save the inner space of rectifier again, make rectifier mould institute and hold to such an extent that rectifying device is more that rectification effect is good.In addition,, not only overcome the point discharge problem of traditional integral formula cast structure owing to adopt the segmentation rectification, and not high to manufacture process requirement.

Description of drawings

Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.

Embodiment

As shown in Figure 1 and Figure 2, section type rectifier for electronic accelerator of the present invention contains seven rectification boxes 1, and these rectification boxes 1 are cuboid, and its outside is surrounded by housing, and they link together by four connecting rods 3 each other.Be provided with fixed head 5 on the same end face of rectification box 1, this fixed head is processed to the U font, thereby their two ends are upturned.The horizontal segment of U font fixed head 5 is fixed on the end face of rectification box 1, and they all are equipped with ball discharge 2 along the closure layout of rectification box 1 on their two perk ends.All be welded with screw mandrel on the said ball discharge 2, the two ends of fixed head 5 all are processed with through hole, the two ends that ball discharge 2 is fixed on fixed head 5 by nut 4, screw mandrel on it and this through hole.2 of ball discharges on two adjacent fixed head 5 neighboring terminals leave the gap.Be provided with barricade 6 on rectification box 1 end face relative with ball discharge 2 is installed, one end of these barricades 6 is fixed on the corresponding rectification box 1, their other end all to same direction stretch out and and adjacent rectification box 1 on 6 of barricades be the gap-like overlaid, thereby constitute spatial distribution electric capacity at lap.These electric capacity are chained together, load sharing voltage, played protective effect to shielding box 1.Especially when bigger vibration occurring, the surge voltage of 1 generation of rectification box can absorb by these distributed capacitance, thereby rectification box 1 is protected.
