Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.

[0024] The technical concept of the present invention: the current life prediction is simplified, and only the influence of temperature factors on the life of the dry-type transformer is considered. This method first calculates the service life of the current dry-type transformer at its own temperature, and then calculates the service life of the dry-type transformer under the influence of the current temperature. Life and the current sampling period, the remaining life in the current sampling period can be calculated and determined. The invention is applicable to the calculation of the remaining service life of dry-type transformers in which all coils are poured with epoxy resin.

Abstract

The invention proposes a method and device for detecting the remaining life of a dry-type transformer. The detection steps are (1) collecting the temperature of the dry-type transformer itself and the temperature of the environment where the dry-type transformer is located; The ambient temperature calculates the service life of the dry-type transformer at its own temperature; (3) Determine the remaining life of the dry-type transformer according to the current sampling period, the service life before the current sampling period, and the service life calculated in step 2). The invention only needs to collect the temperature of the dry-type transformer itself and the temperature of the environment where the dry-type transformer is located, and can calculate the remaining life of the dry-type transformer in the current sampling period in real time. The remaining life of the type transformer can provide accurate reference time for maintenance workers and other staff.

Description

technical field [0001] The invention specifically relates to a method and device for detecting the remaining life of a dry-type transformer. Background technique [0002] The stability and safe operation of the power system are the key to ensure the continuous and stable output of electric energy of the power system. With the rapid development of my country's power grid scale, users have higher requirements for the stability and reliability of the power system while pursuing basic electricity demand. Whether it is domestic electricity, industrial electricity, etc., once the power system fails, it will cause serious economic losses, so it is very important to improve the stability of the power system. Among them, the transformer is an important part of the power system, and the life of the dry-type transformer is a key factor for the continuous, safe and stable power supply of the system. [0003] Factors that affect the life of dry-type transformers include temperature, hum...
