的车站级联锁。
测试间的联锁条件可在订单文件中找到。可在此处找到用户指定的联锁条件。
必须检查所有可能的情况。电压互感器或传感器对于距离、比较和定向功能非常重要。
除了测试极性、变比和磁化特性外,还必须在测试期间检查变压器/传感器的接线
测验
5.5.1电流互感器
变压器必须具有正极绕组。
这可以用9 V电池和模拟直流电压表轻松检查。如果电流互感器的初级线圈连接到蓄电池,则模拟电压表
二次侧连接必须显示正极。当蓄电池断开时,电压表必须测量负脉冲。
蓄电池正子必须连接到初级线圈的P1和
正此极性检查也称为配线测试,必须对每个芯进行。到

变压器或带电流表的保护柜。This polarity check, also referred to as patch test, must be run for every core. To
guarantee correct operation even with a multi core current transformer with different
cores such as protection and measuring cores, it is recommended that the magnetizing characteristic (hysteresis) be recorded. A Variac with appropriately high voltage is
connected to the secondary terminals. The flowing current is measured while the output voltage is rising. The characteristic of the measured values, voltage over current,
yields the magnetizing characteristic of the core, which can then be compared with
the manufacturer's data.
The transformation ratio of the current transformer cores is checked with a special
primary current feed device. The feed device is primarily connected to the current
transformer and the secondary value is measured at the secondary terminals of the
transformer or at the protective cabinet with an ampere meter. inpvoltage transformers or sensors is very important for distance, comparison and directional functions.
In addition to testing the polarity, the transformation ratio and the magnetizing characteristic, the wiring of the transformers/sensors must also be checked during these
test.
5.5.1 Current transformer
The transformers must have a positive winding.
This can be easily checked with a 9 V battery and an analog DC voltmeter. If the primary coil of the current transformer is connected to the battery, th
