一种油浸式变压器有载分接开关油室的测温装置
摘要：
本发明一种油浸式变压器有载分接开关油室的测温装置，包括有测温探头，测温探头通过光缆与光纤光栅解调仪相连，光纤光栅解调仪连接预警模块。所述的测温探头包括光纤光栅温度传感器和绝缘外壳，测温探头接入变压器分接开关油箱。所述的光纤光栅温度传感器是GYT600陶瓷单端式光纤光栅温度传感器。本发明能够对变压器有载分接开关油室实施准确、快速的测温，可靠性好，并且可以直接测分接开关油室内部温度及时反映故障并发出预警。
摘要（英）：

The invention discloses a temperature measurement device of an oil-immersed transformer on-load tap-changer oil chamber. The temperature measurement device comprises a temperature measurement probe which is connected with a fiber bragg grating demodulation instrument through a cable, and the fiber bragg grating demodulation instrument is connected with an early-warning module. The temperature measurement probe comprises a fiber bragg grating temperature sensor and an insulating shell and is connected into a transformer tap-changer oil tank. The fiber bragg grating temperature sensor is a GYT600 ceramic single-end-type fiber bragg grating temperature sensor. The temperature of the transformer on-load tap-changer oil chamber can be accurately and fast measured, reliability is high, the internal temperature of the tap-changer oil chamber can be directly measured, faults can be reflected in time, and an early warning can be given.
