Temperature measurement cable

Abstract

The invention discloses a temperature measurement cable which comprises a temperature measurement wire, an insulation protection sleeve and a shielding protection sleeve, the insulation protection sleeve sleeves the outer side of the temperature measurement wire, and the shielding protection sleeve sleeves the outer side of the temperature measurement wire. According to the temperature measurementcable provided by the invention, the outer side of the temperature measurement wire is sleeved with the insulating protection sleeve, so that the temperature measurement wire is protected. The shielding protection sleeve is arranged on the outer side of the temperature measurement wire, the measurement deviation generated by electromagnetic interference is reduced, the temperature measurement wire is more suitable for measurement in high-voltage, high-magnetic-field and greasy-dirt environments, measurement accuracy and the durability of the temperature measurement cable are improved, and therefore, the temperature measurement accuracy is improved while the service life of the temperature measurement wire is prolonged.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a temperature measuring cable. Background technique [0002] With the construction and development of ultra-high voltage and ultra-high voltage power grids, reactors and transformers as the main equipment will be more widely used. With the construction and development of ultra-high voltage and ultra-high voltage power grids, reactors and transformers as main equipment will be more widely used, and the temperature test of the factory test is particularly important for product testing. [0003] Reactors, transformers and other equipment need to be tested for temperature rise before leaving the factory. Specifically, after a large current is applied to the product to reach the rated loss, the temperature rise of the product's oil surface and oil pipeline is measured. Due to the large size of the product, each product has about 10-20 temperature measurement points. In order ...

AI Technical Summary

Problems solved by technology

Due to the large size of the product, each product has about 10-20 temperature measurement points. In order to ensure the safety of the test personnel, the temperature measurement end is drawn from the product with high voltage and high magnetic field, and the temperature measurement line is introduced into the temperature measuring instrument in the control room. The measurement line The cable is too long and the environment is oily, causing the cable to be easily damaged, and in a high magnetic field environment, the accuracy of temperature measurement is reduced
