Passive cable temperature monitoring device with waterproof function

带有防水功能的无源式电缆温度监测装置

Abstract

The present invention provides a passive cable temperature monitoring device with a waterproof function and belongs to the electric power equipment field. According to the passive cable temperature monitoring device, magnetic flux rings are wound on a cable along the axis direction of the cable; a temperature monitoring device is attached onto the surface of the cable; the magnetic flux rings are provided with wires; and the magnetic flux rings are connected with the temperature monitoring device through the wires. After the cable is electrified, magnetic flux in the magnetic flux rings is made to change based on the electromagnetic induction principle, so that current is generated in the magnetic flux rings; and the generated current can supply power for the temperature monitoring device, so that the temperature monitoring device can obtain the surface temperature of the cable. Compared with the prior art according to which a button battery is used and is needed to be replaced regularly, the passive cable temperature monitoring device of the invention can assist in saving a lot of manpower and material resources and reducing maintenance costs.
本发明提供了带有防水功能的无源式电缆温度监测装置,属于电力设备领域,包括在电缆上设有沿电缆轴线方向缠绕的磁通圆环,在电缆表面贴附有温度监测装置,磁通圆环上设有导线,磁通圆环通过导线与温度监测装置相连。通过电缆通电后,基于电磁感应原理使得磁通圆环内的磁通量发生变化,进而在磁通圆环内产生电流,产生的电流能够为温度监测装置供电,使得温度监测装置能够获取电缆表面温度,相对于现有技术中采用纽扣电池需要定时更换的方案,能够节省大量的人力物力,降低了维护成本。
