GE DS200RTBAG3AHC继电器端子板
过滤器接地端子(5)与安全接地端子分开,以便在PQM接线的情况下对开关设备进行介电测试。介电测试期间,必须拆除过滤器接地端子连接。正确安装后,PQM符合IEC 801和ANSI C37.90.1的抗干扰要求。2.2.3 VT输入PQM接受电压输入(V1、V2、V3)和公共电压(Vn)之间0至600 V AC的输入电压。这些输入可以直接连接或通过外部VT提供。如果要测量大于600 V AC的电压,则需要外部VT。当使用输入V1、V2和V3测量线对线量时,确保电压公共输入Vn接地。该输入用作测量电压输入的参考。PQM电压输入的所有连接应使用额定为2安培的HRC保险丝连接,以确保足够的中断能力。
The Filter Ground Terminal (5) is separated from the Safety Ground Terminal (6) to allow dielectric testing of switchgear with the PQM wired up. Filter Ground Terminal connections must be removed during dielectric testing. When properly installed, the PQM meets the interference immunity requirements of IEC 801 and ANSI C37.90.1. 2.2.3 VT Inputs The PQM accepts input voltages from 0 to 600 V AC between the voltage inputs (V1, V2, V3) and voltage common (Vn). These inputs can be directly connected or supplied through external VTs. If voltages greater than 600 V AC are to be measured, external VTs are required. When measuring line-to-line quantities using inputs V1, V2, and V3, ensure that the voltage common input Vn is grounded. This input is used as a reference for measuring the voltage inputs. All connections to the PQM voltage inputs should be connected using HRC fuses rated at 2 Amps to ensure adequate interrupting capacity.
