Problems solved by technology

When the temperature drops rapidly, the dissolved water inside the transformer oil will precipitate and become suspended water; when a large amount of suspended water gathers, it will form large water droplets and separate from the transformer oil, depositing at the bottom of the oil tank, causing insulation failure and posing potential dangers

Embodiment

[0018] In this embodiment, the oil-water cooler 1 has a double-pipe structure.

[0019] In this embodiment, the steam inlet pipeline 202 is provided with a pressure relief valve 10 , and the pressure relief valve 10 is located between the steam inlet and the electric valve A 7 . The pressure relief valve 10 plays a role of releasing pressure on the pipeline and the steam heater 2 to avoid blockage, thereby improving the use safety of the steam heater 2 . The closing time of the pressure relief valve 10 can be designed as required, and can be controlled by a time relay.

[0020] In this embodiment, the oil-water cooler 1 is provided with a leakage alarm 11 . Once water leakage or oil leakage occurs, oil or water will flow into the leakage alarm 11 to trigger an alarm, so that technicians can find out and solve it in time, thereby preventing oil or water from leaking into the transformer. Further, the leakage alarm 11 is a liquid level alarm, that is, the leakage alarm 11 is a...

Abstract

An intelligent temperature regulation system for transformer oil provided by the invention can be used for carrying out intelligent temperature regulation control on the transformer oil, and comprises an oil-water cooler, a steam heater and a microcomputer controller; an oil inlet pipeline, an oil outlet pipeline, a water inlet pipeline A and a water outlet pipeline A are arranged on the oil-water cooler, and a bracket A is arranged at the bottom of the oil-water cooler; a steam inlet pipeline, a steam outlet pipeline, a water inlet pipeline B and a water outlet pipeline B are arranged on the steam heater, and a bracket B is arranged at the bottom of the steam heater; the water outlet pipeline B is communicated with the water inlet pipeline A through a connecting pipeline; a temperature sensor A is arranged on the oil inlet pipeline, and a temperature sensor B is arranged on the water outlet pipeline B; an electric valve A is arranged on each of the steam inlet pipeline and the steam outlet pipeline; a bypass pipe is communicated with the connecting pipeline, and an electric valve B is arranged on the bypass pipe; and the temperature sensor A, the temperature sensor B, the electric valve A and the electric valve B are electrically connected with the microcomputer controller. Correspondingly, the invention further provides an intelligent temperature adjusting method for the transformer oil.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer oil intelligent temperature regulation system and a transformer oil intelligent temperature regulation method. Background technique [0002] Transformer is one of the core electrical equipment in the power system, and its safe operation is directly related to the safety and stability of the power grid. Transformers can be divided into dry-type transformers and oil-immersed transformers according to the cooling method. The iron core and winding of the oil-immersed transformer are immersed in transformer oil; as one of the important components of the transformer, transformer oil plays the role of insulation and cooling. role. When the temperature of the transformer oil is too high, it will cause insulation damage, so it is necessary to use a cooler to dissipate heat from the transformer oil when the transformer is working. [0003] However, if the temperature o...
