Abstract
The utility model discloses a coil of an X wire tube filament transformer, comprising an inner support sleeve, an outer rigid support sleeve, an inner wire and an outer wire, wherein the inner wire is wound round the inner support sleeve, and the outer wire is wound round the outer support sleeve which is arranged outside the inner support sleeve. Because of the rigid support sleeve, all the winding support parts and the coil have good positions, and the position of the coil changes slightly relatively to surrounding parts, thereby effectively ensuring creepage distance of the coil, and ensuring consistency of coil quality during assembly.
Description
[technical field]
The utility model relates to a kind of filament transformer line bag of transformer line bag, especially medical X-ray high-frequency and high-voltage generator.
[background technology]
Have now in high-frequency and high-voltage generator, filament transformer is the critical component of medical X-ray camera chain medium-high frequency high pressure generator for the power supply of bulb filament.Filament transformer is made up of structures such as magnetic core, coil at different levels, support set and installed parts.Coils at different levels and support set are formed the line bag.The relative position of each coil can have appreciable impact to the performance of transformer in the line bag.Mostly prior art is to adopt several flexible insulating materials as support between the lead and insulation system, and the lead location all depends on this class formation with support.Online bag is the line of coiling successively bag from inside to outside when processing, and this just may influence the relative position of inner conductor in the layer line pack arrangement and change the creepage distance of design in advance outside coiling, thereby influences the performance of filament transformer.There is following shortcoming in existing in sum line bag processing mode: 1. the technique for coiling complexity of line bag; 2. the relative position of line bag interior loop is difficult for guaranteeing that line bag quality conformance is poor; 3. line bag creepage distance is not easy to meet design requirement.
[summary of the invention]
In order to solve above technical problem, herein disclosed is a kind of filament transformer line bag, the outer support set, inner conductor and at least one the outer layer conductor that comprise internal layer support set, at least one rigidity, wherein, described inner conductor is on the internal layer support set, described outer layer conductor is on outer support set, and described outer support set is enclosed within the internal layer support set outside.
Also comprise end cap in the preferred scheme, described end cap has endoporus and cannelure, and the endoporus of described end cap is connected with the internal layer support set, and the cannelure of described end cap is connected with outer support set.
Also comprise end cap, described end cap has endoporus and cannelure, and described internal layer support set inserts endoporus, described outer support set and cannelure clamping.
Described internal layer support set week upwards has groove, and described inner conductor is on groove.
Described outer support set week upwards has groove, and described outer layer conductor is on groove.
Comprise insulating coating, described insulating coating is enclosed within the outside of outer support set and outer layer conductor.
Described outer support set is connected with the internal layer thread of supporting sleeves.
The fairlead that has inner conductor on the described end cap.
The fairlead that has outer layer conductor on the described insulating coating circumference.
This paper also discloses a kind of medical X-ray camera chain, comprises high-frequency and high-voltage generator, and described high-frequency and high-voltage generator contains aforesaid filament transformer line bag.
The line pack arrangement that the utility model proposes is owing to adopted the support set of rigidity, make each coiling strutting piece and lead that good location all be arranged, so lead relatively can great changes have taken place with the position of on every side device, thereby effectively guaranteed the creepage distance of line bag, guaranteed the consistency of line bag quality when assembling.

[embodiment]
1 to 3 be described in further detail in conjunction with the accompanying drawings below by embodiment.
The disclosed structure of embodiment as shown in Figure 1, filament transformer line bag comprises: insulating coating 1, outer support set 2, end cap 3, internal layer support set 4, inner conductor 5 and outer layer conductor 6.Internal layer support set 4 is that the coiling of elementary winding is supported, and inner conductor 5 is wound on the internal layer support set 4.The coiling that outer support set 2 is secondary winding is supported, and outer support set 2 is made up of the insulating material of rigidity, and here " rigidity " refers to and be not easy to take place deformation, and outer layer conductor 6 is wound on the outer support set 2.Insulating coating 1 is the outer insulation external member of secondary winding, and it cooperates the realization axial location by nesting together the realization radial location with outer support set 2 in the mode of interference fit with the step on outer support set 2 surfaces, and insulating coating 1 mainly plays the effect of insulation.Outer support set 2 and internal layer support set 4 by with end cap 3 with the nested assembling of the mode of interference fit, locate internal layer support set 4 and outer support set 2 in the end of nested structure with the endoporus and the cannelure of end cap 3.As shown in Figures 2 and 3, the lead-out wire of inner conductor 5 is drawn by the internal layer wire hole 31 on the end cap 3, and the lead-out wire of outer layer conductor 6 is drawn by the outer wire hole 11 on insulating coating 1 circumference.
In the time of inner conductor 5 coilings, need inner conductor 5 is wound on the groove in the middle of the internal layer support set 4, the step at groove two ends just easily positioning lead in order to avoid on roll, slide at it.In the layer conductor 6, need be wound on outer layer conductor 6 on the groove of internal layer support set 2 centres outside coiling, and the groove on the outer support set 2 also plays a part same.In the time of the nested assembling of coil, the endoporus interference fit location on internal layer support set 4 and the end cap 3, the cannelure tight interference fit on outer support set 2 and the end cap 3.
Structure has guaranteed the consistency of line bag quality when assembling thus.When online job contract is done,,, thereby effectively guaranteed the creepage distance of line bag so coil position relative and device on every side does not have any variation because each support set and lead all have good location.
The utility model can also adopt other execution mode, and for example: the line pack arrangement not only comprises an outer layer conductor 6 and an outer support set 2, can also comprise a plurality of outer layer conductors 6 and outer support set 2, and insulating coating is enclosed within outermost layer; Internal layer support set 4 also can directly be connected by threaded engagement with outer support set 2, even can connect by glue, has not so just needed end cap 3.
A kind of medical X-ray camera chain comprises high-frequency and high-voltage generator, and described high-frequency and high-voltage generator contains the filament transformer line bag in the various as mentioned above embodiments.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
