電源装置の小型化が非常に困難であり、また作業性、信
頼性、コストの面で問題があった。Problems to be Solved by the Invention However, in such a conventional structure, since the discharge resistor 4 and the arcing protection resistor 6 are individually connected to the printed wiring board 6,
In addition to requiring space for two resistors, an insulation distance of 14 is required due to the high potential difference between points A and B, which makes it extremely difficult to miniaturize the high voltage power supply, and also reduces workability, reliability, and cost. There was a problem with this.

The purpose of the present invention is to provide a high-voltage power supply device that achieves improved performance and cost reduction.

作 用
この複合抵抗を使用することにより、放電抵抗と゛アー

The insulation distance required at the high potential difference portion of the protective resistor can be reduced because it is secured only by the pitch of the three terminals provided in the composite resistor.
実施例
以下、本発明Ω一実施例を添付図面に基づいて説明する
。Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings.
第１図において高圧トランス１と整流用ダイオード２．
平滑コンデンサ３及び上記コンデンサ３の放電抵抗と、
アーキング保護抵抗を第３図で示すように一枚の基板上
に設けた複合抵抗７を印刷配線板６に、絶縁距離を確保
したかたちで組込み、第２図で示す高圧整流回路を構成
した物である。In FIG. 1, a high voltage transformer 1 and a rectifying diode 2.
a smoothing capacitor 3 and a discharge resistance of the capacitor 3;
A composite resistor 7 with an arcing protection resistor provided on a single board as shown in Fig. 3 is incorporated into a printed wiring board 6 with an insulation distance secured, thereby configuring a high voltage rectifier circuit as shown in Fig. 2. It is.
まず放電抵抗４とアーキング保護抵抗５を個々の抵抗で
第２図に示す高圧整流゛回路を構成した場合について説
明する。First, a case will be described in which the discharge resistor 4 and the arcing protection resistor 5 are used as individual resistors to form a high-voltage rectifier circuit shown in FIG.
高圧電源の出力電圧をＤＣｓＫＶＭＡＸとすると、放電
抵抗４の両端には上記と同じ電位差が生じ、またアーキ
ング保護抵抗５の両端と放電抵抗４の低圧側間も上記と
同様の電位差が生じている。When the output voltage of the high voltage power supply is DCsKVMAX, the same potential difference as above occurs between both ends of the discharge resistor 4, and the same potential difference as above also occurs between both ends of the arcing protection resistor 5 and the low voltage side of the discharge resistor 4.
この時、放電抵抗４の高圧側とアーキング保護抵抗５の
片方は接続されているため電位差は放電抵抗４の両端の
み考えればよいが、アーキング保護抵抗５の他方は出力
リード線８に接続されており、この点と放電抵抗の低圧
側との電位差は考慮する必要がある。At this time, the high voltage side of the discharge resistor 4 and one side of the arcing protection resistor 5 are connected, so the potential difference only needs to be considered at both ends of the discharge resistor 4, but the other side of the arcing protection resistor 5 is connected to the output lead wire 8. Therefore, it is necessary to consider the potential difference between this point and the low voltage side of the discharge resistor.
電位差がＤ Ｃ９ＫＶとすると必要になる沿面絶縁距離
は、実績データにより約１ｏｎ程となり上記２個所につ
いては確保する必要がある。If the potential difference is DC9KV, the required creepage insulation distance is about 1 on according to actual data, and it is necessary to ensure it for the above two locations.
次に、放電抵抗４とアーキング保護抵抗６の代りに複合
抵抗アを使用した場合について説明する。Next, a case will be described in which a composite resistor A is used instead of the discharge resistor 4 and the arcing protection resistor 6.
複合抵抗子は第３図で示す構造とする。The composite resistor has the structure shown in FIG.
端子９〜１０はアーキング保護抵抗５ａ、端子１０〜１
１は放電抵抗４ａを構成し、抵抗体はセラミック基板１
２に載せ絶縁物１３でモールドされている。Terminals 9-10 are arcing protection resistors 5a, terminals 10-1
1 constitutes a discharge resistor 4a, and the resistor is a ceramic substrate 1
2 and molded with an insulator 13.
このため放電抵抗４とアーキング保護抵抗６は複合抵抗
７の内部で接続された形になっており部品点数の削減、
組立工数の低減によりコストダウンとなる。Therefore, the discharge resistor 4 and arcing protection resistor 6 are connected inside the composite resistor 7, reducing the number of parts.
Costs are reduced by reducing assembly man-hours.
また、低圧側１１ａと高圧側１０ａ、９ａ間は放電抵抗
４ａによって絶縁距離が確保されるため従来必要であっ
たアーキング保護抵抗５の両端と放電抵抗４の低圧側の
絶縁距離は、考慮しなくてもすむので小形化が図れる。In addition, since the insulation distance between the low voltage side 11a and the high voltage sides 10a and 9a is ensured by the discharge resistor 4a, the insulation distance between both ends of the arcing protection resistor 5 and the low voltage side of the discharge resistor 4, which was conventionally necessary, is not considered. Since it can be made smaller, it can be made smaller.
