7 安装与接线 7.1 NZQ2 双电源切换控制器以其完善的设计思路, 保证每个测 量量的准确性, 其接线方式如下, 适用于两路三相四线制 400V 供 电系统的测量与切换控制(见图 2)。 7.2 初次安装时应作好以下工作,以保证维护尽可能方便。 7.2.1 应提供一个 CT 盒, 这样使 NZQ2 双电源切换控制器的电流

输入不连接时, 不会使 C T 开路,短路盒接线应使保护继电 器的 功能不受影响。 7.2.2 NZQ2 必须牢固安装,以防止震动导致电气安全事故。 7.3 NZQ2 双电源切换装置外部接线图(见图 3)。 注意: 1、 接线时, 电压输入回路 (包括电源) 必须在每条线路上串联适 的保险。 2、电流输入回路的阻抗尽量小。在 CT 方式下,主回路处于工作 带电状态时,绝对禁止将 CT 二次侧 (即电流输入回路)开路。 3、必须严格按下面接线图示要求接线,否则将有可能导致装置 损坏,甚至造成人身安全,由此引发的质量问题,不在保修范围内。 4、在进行手动分合操作前,必须将控制器设定在手动状态下。

7.1 The perfect design of NZQ2 switching controller of double power source ensures the correctness to each measuring. The wiring way is as follow, which is suitable for the measuring and switching control of three-phase four-line system of 400V power supply system (referring Fig.).

注:开关量输入为接地有效 Note: Input of switch quantity is effective to earth 7.2 The following works shall be made to the first installation to ensure its convenience in maintaining. 7.2.1 A CT box is supplied, so that open circuit of CT will not occur when the current of NZQ2 switching controller of double power source is not connected, the wiring of short circuit box will not impact on the function of protective relay. 7.2.2 NZQ2 must be fixed closely to avoid shocking, leading

electrical accident. 7.3 External wiring diagram of NZQ2 switching device of double power source ( referring to Fig.3)。 NZQ2 双电源切换装置外部接线图 External wiring diagram of NZQ2 switching device of double power source 1 路输入 one route input Ⅱ路输入 two-route input 负荷 load 图3 Fig. 3

Note: 1. Proper fuse must be connected in series on each line to the input circuit of voltage when wiring is made. 2. The resistance of current input circuit is small as possible. Open circuit of secondary side (that is, current input circuit) is not allowed absolutely under the condition of CT and main circuit is in live and in working condition. 3. It must be done as the wiring diagram strictly, otherwise, the device may be damaged, or leading to an accident, which is not guaranteed. 4. The controller must be set under manual condition before manual opening and closing operation.
