Description

Technical Field

[0001] The invention belongs to the technical field of transformer temperature measurement, and in particular relates to a transformer temperature measurement device. Background Art

[0002] Transformer is a kind of static electrical equipment used to transform AC voltage and current and transmit AC power. Transformer is divided into oil-immersed transformer, dry-type transformer and gas-insulated transformer according to the insulation medium. It is one of the important equipment in the power distribution system. Oil-immersed transformer has the characteristics of high insulation, low cost and high heat resistance and is widely used. With the development of the national economy and the continuous growth of residents' consumption capacity, the residents' electricity load is getting bigger and bigger. Especially in summer, the load of high-power electrical equipment such as residents' air conditioners is concentratedly released, which may cause the distribution transformer to overload. In the use of oil-immersed transformer, the body of the transformer is immersed in oil, so that the heat generated by the body when working will be transferred to the oil, causing the oil to heat up. Therefore, in the maintenance of oil-immersed transformer, maintenance personnel need to measure the temperature of the oil in the transformer.

[0003] The Chinese patent application number CN202211377121.9 discloses a transformer temperature measuring device for power maintenance, including a temperature measuring device, which is used to measure the temperature of the transformer body. The transformer body is equipped with a plurality of sleeves for inserting the temperature measuring device, the end of the sleeve is closed, and the head of the sleeve is open. The temperature measuring device includes a plug-in rod that can be inserted into the sleeve and a temperature measuring structure embedded on the outer surface of the plug-in rod head. The tail end of the plug-in rod is equipped with a display. The temperature measuring structure includes a socket fixed to the plug-in rod, a block arranged on the front side of the socket, and a temperature sensor embedded inside the block. When the temperature measuring device is inserted into the sleeve, the outer surface of the block always abuts against the inner wall of the sleeve. In the present invention, by installing the sleeve on the transformer body, when the maintenance personnel perform daily internal oil temperature detection on the transformer body, the temperature measuring device can be inserted into the sleeves at different positions to conveniently measure the temperature of the oil in the transformer body at different depths, so that the measured temperature value is closer to the actual temperature of the oil.

[0004] However, when the above device is actually used, when the plug-in rod and the thermometer are inserted into the bushing, the thermometer will always be in contact with the inner wall of the bushing. When the plug-in rod and the thermometer move, friction will occur between the thermometer and the inner wall of the bushing, which may easily cause damage to the thermometer. The friction will also affect the temperature measurement of the thermometer. In addition, since multiple bushings are set on the transformer body, when the staff wants to measure the temperature at different positions, they need to frequently pull out the plug-in rod and the thermometer and insert them into different bushings.

[0005] In view of this, the present invention is proposed. Summary of the invention
