南澳电气 NAZKD真空开关真空度测试仪 以单片计算机为主控单元，测试过程完全实现

产品简介

真空断路器是电力系统中普遍使用的高压电器，其核心部件是真空灭弧室，由于灭弧室是以真空条件作为工作基础的，所以它不象油开关，SF6开关那样容易检测其质量。传统上，真空断路器用户判断灭弧室真空度的方法是工频耐压法，这种方法只能粗略判断真空度严重化的灭弧室。

NAZKD真空开关真空度测试仪是真空灭弧室的真空度的鉴定设备，以单片计算机为主控单元，测试过程完全实现自动化。该仪器的采样设计一改以往采用电流峰值做标定的方法，而采用离子电荷来做标定。这样，有效地抑制了测试过程中瞬态电源的干扰，使测试稳定可靠。由于采用计算机为主控单元，该仪器能很方便地扣除由于环境因素产生的漏电电流。本仪器最突出的特点是：实现了真空灭弧室的免拆卸测量，直接显示真空度值，使真空断路器用户详细掌握灭弧室的真空状态，为有计划地更换灭弧室提供了可靠的依据，为电网的安全运行提供了有力保障，克服了工频耐压法仅能判断灭弧室是否报废的缺陷。

Product introduction

With the non-oil pressure switch rise of the tide, with its unique advantages vacuum switch has been widely promoted andapplied.Traditional detectionmethod is "pressure method", that is breaking the vacuum switch is in a state in which static and dynamic touch certain voltage is applied between the head, the size oftheleakage current detected,the quality of vacuum inferred. Advantages of this method are: simple operation; drawback: only qualitatively detect the quality of vacuum tube; and the degree ofvacuum10-4 ~ 10-1Pa can notaccurately distinguish between, it is impossible to determine the leakage trends.

NAZKD vacuum switch vacuum tester, the previous generation of products based on the upgrading of the product. The productiscompact, light andcompact models, shorter test time, measurement reliability, stability, higher accuracy, function more perfect.

Also called name

vacuum degree tester, HV switch vacuum switch tester
