炉前使用直读光谱仪为什么需要稳压电源?
<p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">通常情况下,越是大型的分析仪器对电源的要求越是高,直读光谱仪也不例外。稳定的电源对于直读光谱仪测定数据的重现性和再现性是极为重要。</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%;

mso-ascii-font-family: Calibri; mso-hansi-font-family: Calibri;"><span style="color: rgb(0, 0, 0); font-family: 宋体;">由于炉前电压波动比较大,电源的电压难以稳定,无法为直读光谱仪提供稳定的电压;为了确保直读光谱仪正常工作和测定数据的准确,需要配备适宜的稳压电源来保证仪器有相对稳定的电压。仪器要求其电源电压的变化控制±</span><span style="color: rgb(0, 0, 0); font-family: Calibri;">5%</span><span style="color: rgb(0, 0, 0); font-family: 宋体;">以内是不会对数据测定和仪器寿命带来影响。</span></span></p><p style="margin: 0pt; text-align: center; line-height: 1.75em;"><span style="color: rgb(0, 0, 0);

mso-ascii-font-family: Calibri; mso-hansi-font-family: Calibri;">不合格的稳压电源给仪器带来的后果是非常严重的,为了保证仪器电压稳定,仪器的稳压电源必须单独配备,对于未经仪器厂家工程师验证的稳压电源禁止使用。</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0);

mso-ascii-font-family: Calibri; mso-hansi-font-family: Calibri;"><span style="color: rgb(0, 0, 0); font-family: 宋体;">直读光谱仪电源线连接禁止与打电动机、通风机、空调机、马弗炉等大的用电设备共用一条供电线路,更不能和中频炉等生产设备共用电源,因为这些大功率的设备启动时供电线路的电压大幅度的波动,同样会造成电源电压不稳定。一般情况下,配置的</span><span style="color: rgb(0, 0, 0); font-family: Calibri;">1KVA</span><span style="color: rgb(0, 0, 0); font-family: 宋体;">磁饱和稳压电源就可以满足</span><span style="color: rgb(0, 0, 0); font-family: Calibri;">Noble T7</span><span style="color: rgb(0, 0, 0); font-family: 宋体;">直读光谱仪的需求,为了稳压电源的安全,稳压电源前应该安装一个可以手动控制(启动、中止)的交流接触器(</span><span style="color: rgb(0, 0, 0); font-family: Calibri;">220V/45A</span><span style="color: rgb(0, 0, 0); font-family: 宋体;">),交流接触器安装在离地</span><span style="color: rgb(0, 0, 0);

mso-ascii-font-family: Calibri; mso-hansi-font-family: Calibri;"><span style="color: rgb(0, 0, 0); font-family: 宋体;">在直读光谱仪运转中,还应该观察稳压电源装置的变化,看指示灯显示是否为过压或欠压,如果出现这种情况,直读光谱仪不要激发工作,因为直读光谱仪运行中电压波动超过±</span><span style="color: rgb(0, 0, 0);
