1、 概述 该系列产品采用大规模专用集成电路及可靠的电子元件设计制造而成。无功电能计量采用正弦设计（即真无功），无论电网三相电压、电流是否平衡，均能准确计量有功（无功）电能，产品出厂前均经高温高压通电工作老化和严格测试，质量可靠，产品符合 GB/T172215-1998 标准和 IEC1036 国际标准，适用于广大城乡三相电用户及电力部门安装使用 2. 技术参数 电表常数：6400imp/kWh、3200imp/kWh、1600imp/kWh环境工作条件：-30℃～+55℃，相对湿度不超过85% （+25℃）。抗电磁干扰能力强，可在恶劣电力环境下运行。强化工艺控制，独特工艺保证，高可靠性设计。名称型号精度参比电压基本电流（A）功耗电子式三相有（无）功电度表DTS---0.5级1.0级（有）功3 X 57.7/1003 X 1003 X 220/380 2.5(10)5(20)10(40)20(80) 1.0W1. Product Introduction. The series of products are made of mported speciai use slai and high reliable electric energy measure ment (hat is real reactive) Whether the threephase voltageand current of the electric network is balance,Energy accuray. Before deliver, en ationand aging tests.so the quality are reliable. In addition, these products are conformed to GB/T17218-1998 Standard and village users and power departments with three-phase electricity .2. Function and Features. Measure three-phase active energy,do not need calibrate for long-term operation. Three-phase power supply,the energy meter can work normally once any one or two phases are broken. Wide service temperature range; Assuming function of defect phase indication or voltage indication. Way of display:Register、LCD、digital tube; Remote interruption of power supply function.3、Main Technical Data.
