Abstract

PURPOSE:To prevent the coil slip in each coil layer, by preparing insulator retainers common to multistage secondary coil layers with different winding widths. CONSTITUTION:1 represents a center core, the layer 2 of the primary coil is arranged thereon, the secondary coil II is wound up via a layer insulating paperIon the outside of this layer 2, and multistage secondary coil layers 3, 4, 5... with different winding widths are arranged. Then, the insulator retainer 10 common to said coil layers 3, 4, 5... is so arrangement-fixed as to pinch the secondary coil layers from the both sides thereof on the primary coil layer 1. In this manner, since the both sides of the secondary coil layer are fixed, coil slips are not generated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-pressure silance structure in an X-ray generator in which an X-ray tube and a high-voltage transformer are assembled in the same container.

X-ray tube and high-voltage transformer integrated into the same container
Line generators are used in places with relatively poor footing, such as construction sites, so they are often subject to shock and vibration. on the other hand,
The X** raw equipment in such applications is used because it is necessary to be small and lightweight. For example, the first
Figure 1 = As shown in Figure 1, a layer of primary coils is provided for the center core a I; on top of that, a secondary coil is wound through interlayer insulating paper to form multi-stage coils with different winding widths. layer c
, d, e... are arranged.

Ru. However, with such a high voltage transformer structure, coil misalignment is likely to occur between the coil layers C and 4. In particular, when subjected to shock or vibration, coil displacement occurs between the lower layer of the coil that supports the weight of the coil and the interlayer insulation paper, or between the coil and the interlayer insulating paper.

This is between several layers of insulating paper stacked on top of each other.

This invention was made based on the above circumstances, and a common insulating material holder is prepared for multiple stages of secondary coil layers each having a different winding width.

This aims to provide a high-voltage transformer structure for the X-ray generator I that prevents the occurrence of coil misalignment between the coil layers.

The present invention will be specifically explained below based on the embodiment shown in FIG. In the figure, reference numeral 1 is the center core, on which layer 2 of the primary coil is placed, and on the outer side of this layer 2, the secondary coil 2 is wound through interlayer insulating paper I. , multi-stage secondary coil layers 1, 4.1, with different winding widths...
・is placed. In this embodiment, the above 1.
Above the secondary coil layer 2 are each secondary coil layer 3.4゜1...
The above coil layer should be sandwiched from both sides against:
J, 4. S...1: A common insulating material holder 10 is arranged and fixed. In the figure, numeral 11 is a scale, and 12 is an equalizer.

In such a configuration, the insulating material holder 10 is commonly used to harden both sides of each secondary coil layer for the relatively lower coil layers 1, 4, 1, etc. that support a considerable coil weight. Therefore, coil misalignment does not occur.

In this embodiment, it is necessary to increase the creepage distance of each secondary coil layer in the first stage to improve the potential distribution and increase the withstand voltage of the holder 10.

Therefore, the exposed surface of the holder 10 is formed into a smooth slope.

As described in detail above, this invention provides two layers of primary coil C2 wound around the core through interlayer insulating paper.
In a structure in which a secondary coil is wound to form multi-stage coil layers with different winding widths, an insulating material holder common to the multi-stage coil layers is used so as to sandwich the coil layer of each secondary coil from both sides. Since the arrangement is fixed, it is possible to prevent the coil layers of each secondary coil, which support relatively large layers, from shifting. Therefore, although the overall structure is a gas-insulated high-voltage transformer, it is resistant to shocks and shocks. The effect is that the resistance to motion is significantly improved.
