Embodiment Construction

[0026] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0027] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention discloses a power transformer cooling performance evaluation system, which comprises a temperature acquisition unit, a humidity acquisition unit, a timing unit, a cooling unit, a working information acquisition unit, a rapid cooling unit, a frequency converter unit, a logic control unit, a power supply unit, a simulation test vehicle and a control terminal, wherein the logic control unit sets an oil temperature peak value and an oil temperature constant value, the timing unit calculates the actual cooling time from the oil temperature peak value to the oil temperature constant value, and the control terminal adjusts the environment parameters of the simulation test vehicle according to the collected environment temperature information, environment humidity information and the working information of the transformer. According to the invention, the temperature acquisition unit, the humidity acquisition unit, the timing unit and the simulation test vehicle are matched to simulate the actual environment of the to-be-tested transformer, so that a comparison basis is provided for the evaluation of the to-be-tested transformer, and the problem that the cooling performance evaluation is separated from the reality is solved.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a system and method for evaluating the cooling performance of a power transformer. Background technique [0002] At present, a transformer is a static electrical device used to transform AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers in terms of their uses: power transformers are necessary equipment for power transmission and distribution, and power user distribution; test transformers can withstand voltage (boost) for electrical equipment Test equipment; instrument transformers are used for electrical measurement and relay protection of power distribution systems (PT, CT); special-purpose transformers include electric furnace transformers for smelting, welding tr...
