Abstract

一个供气体放电幅射管工作用的可调直流电源，它包含一个或多个不可调的电压源，与此不可调电压源相串联的是一个可变的电压源。

Description

气体放电幅射管，例如水银蒸气幅射管，与一般的用电装置不同之处是，它有一条电流-电压特性曲线，该特性曲线之斜率，根据幅射管电流和幅射管种类之差异可以是正的或是负的。因而它需要特殊的电源供电，这种电源应能工作在负的电流-电压特性曲线上。众所周知，这种幅射管的电源，包含串联线圈、漏磁变压器、饱和电抗器、晶闸管调整装置以及接在其后的变压器。这种电源难以适应各种功率的幅射管，而且要求电网电源的特性不能有较大的变化。此外，这种电源的耗电量大、笨重、占地面积大。
本发明将可消除此等弊端。本发明的任务是为气体放电幅射管提供一个可调电源，该电源运行时损耗微小、能够适应电网波动、组合式结构、而且可以很方便地工作于不同型式的幅射管。
解决所述任务的办法是，用一个或多个不可调节的电压源和一个与该不可调电压源串联的可变电压源组成所需的电源。
在一个实施例中，所述的可变电压源的幅值或持续接入时间（脉冲式）是可以无级调节的。
利用附图可对本发明作较详细的说明。附图说明于下：
图1是由不可变的和可变的电压源共同组成的直流电源的原理图;
图2是电源的可变部分的详细的原理图，电源的可变部分用来对幅值进行无级调节;
图3是电源的可变部分，用来对持续接入时间（脉冲式）进行调节。
固定的（不可调的）直流电源U1是和可变的（可调的）直流电压源U2串联相接的。与U2并联了一个续流二极管D，当U2＝0时，幅射管电流可以流过该二极管。符号S表示幅射管，符号Z表示串联阻抗（电感）。由图2可见，电压源U2适用于无级调节，它譬如说可由交流电网三相L1、L2、L3供电，并由晶闸管T1、T2、T3和二极管D1、D2、D3组成桥式电路，由图3可见，电压源U2适用于进行脉冲式调节，该电源也由交流电网的三相L1、L2、L3供电，也有一个桥式电路，该桥由二极管D1到D6组成，这个电源还有一个电子开关T，该电子开关譬如可用一个晶体三极管，或是一个晶闸管，或是一个可关断晶闸管做成。U2只为幅射管S提供所需工作电压的一部分，因而也只为幅射管提供一部分与此相应的电功率。
