一种变压器现场监控装置
摘要：
本实用新型提供了一种变压器现场监控装置，包括电源、变压器结构变化记录仪及变压器磁场变化传感器,所述变压器结构变化记录仪及所述器磁场变化传感器均与数据处理器连接；所述变压器磁场变化传感器可感应到磁场强度的变化，铁芯横截面的变化或者线圈组直径的变化可导致磁场强度的变化，所述铁芯和线圈绕组设在变压器内部。数据处理器接收变压器磁场变化传感器的信息数据并转化为异常信息，所述异常信息存储于变压器结构变化记录仪。现场检查人员无需靠近变压器即可直观地得出用电客户违约用电的行为，提高检查安全性。
摘要（英）：

The utility model provides an on-site monitoring device for a transformer, and the device comprises a power supply, a transformer structure change recorder, and a transformer magnetic field change sensor. The transformer structure change recorder and the transformer magnetic field change sensor are respectively connected with a data processor. The transformer magnetic field change sensor can sense the change of magnetic field intensity. The change of the cross section of an iron core or the change of the diameter of a coil assembly can cause the change of the magnetic field intensity. The iron core and the coil assembly are disposed in the transformer. The data processor receives the information data of the transformer magnetic field change sensor, and converters the information data into abnormal information. The abnormal information is stored in the transformer structure change recorder. An on-site inspection worker can visually find out illegal activities of users with no need to get close to the transformer, thereby improving the inspection safety.
