安科瑞电气股份有限公司 1. 安装使用 1 Installation Guide 1.1 产品概述 1.1 Product Introduction 现阶段,电力系统对于电能的质量提出越来越高的要求,不仅要确保供电稳定可靠,而且供电 的安全性也是重要要求。电力系统中,金属封闭开关设备得到广泛应用,因此开关柜运行的是否稳 定可靠是重中之重,电气设备在运行的过程中由于受到高温、电压、振动以及其他化学作用,将会 使得其绝缘性能降低,会产生局部放电现象,同时又会加速绝缘的恶化情况,会给电力系统造成较 大的经济损失。但是,由于开关柜内部空间狭小、零件繁多、结构复杂,绝缘距离小,因此比其它 电力设备更容易出现绝缘缺陷,从而对设备安全运行带来巨大隐患。 At present, the power system has increasingly high requirements for the quality of electricity, not only to ensure stable and reliable power supply, but also to ensure the safety of power supply. In the power system, metal enclosed switchgear is widely used, so the stability and reliability of the switchgear operation is of utmost importance.
现场局部放电的实际检测频率,随后将检测的局部放电的放电次数和放电频次等数据上传至服务 器。 The APD series high-voltage switchgear partial discharge monitoring device detects the electromagnetic wave radiation generated along with partial discharge and automatically determines the actual detection frequency of on-site partial discharge. Then, data such as the number and frequency of partial discharge detected are uploaded to the server.
