Transformer oil temperature detection device and system

Abstract

The invention discloses a transformer oil temperature detection device and system, and belongs to the technical field of transformer oil temperature detection. The transformer oil temperature detection device and system comprises an oil tank installed on a transformer and a monitoring terminal, the monitoring terminal comprises a main control system, the oil tank is filled with oil, a liquid separation plate is arranged in the oil tank, two ends of the liquid separation plate are fixedly connected with a pair of inner walls of the oil tank respectively, and the upper end of the oil tank is fixedly connected with a water tank. Grading detection of oil is realized, the predictive temperature of the oil is detected in a state that a temperature sensor is isolated from the oil, and the actualtemperature is detected when the temperature sensor is in contact with the oil, so direct and accurate detection of the oil temperature is achieved, isolation protection of the temperature sensor canbe achieved, the temperature sensor is not prone to being affected by long-time soaking of oil and the high temperature of the oil, the detection performance of the temperature sensor is guaranteed, and therefore the accuracy of an oil temperature detection result is further guaranteed.

Description

technical field [0001] The invention relates to the technical field of transformer oil temperature detection, and more specifically, to a transformer oil temperature detection device and a system thereof. Background technique [0002] The transformer is composed of iron core, winding, insulating bushing, tap changer, oil tank, and cooling part, etc. The parts of the transformer play a role of mutual insulation. The transformer is a static electrical device. According to the principle of electromagnetic induction, the transformer converts energy in the circuit between the windings. When the winding on one side of the transformer passes through the current, then a magnetic field will be generated, and a closed circuit will be generated. The changing magnetic flux causes a changing magnetic flux in the transformer, and through this changing magnetic flux, a changing electromotive force is generated in the secondary coil, so that the current in the circuit will drive the load to...

Problems solved by technology

However, the temperature sensor is generally installed inside the oil tank and immersed in the oil, so that the sensor is always affected by the immersion of oil and the high temperature of the oil, and the detection performance of the sensor will cause damage, thus affecting the detection result of oil temperature
