Problems solved by technology

[0003] In order to ensure the good internal operation of the transformer, it is basically a closed environment. Generally, a pressure relief valve is installed on the top of the transformer. Explosion and discharge will cause bubbles in the heat transfer oil to form high pressure. The pressure relief valve gener

Abstract

The invention relates to the field of pressure release of transformers, and particularly relates to cooling equipment with an early warning function for a pressure release process of an oil-immersed transformer. The equipment comprises a main body, an expansion mechanism, a heat dissipation mechanism, a pressure release mechanism, a butt joint mechanism and an early warning mechanism. The expansion mechanism is arranged to adapt to oil expansion or contraction along with the use condition of a main body, the pressure release mechanism is arranged to release pressure when the interior of the main body is abnormal, the main body is prevented from being deformed or exploded, the heat dissipation mechanism is arranged to play a heat dissipation role on the pressure release mechanism, the pressure release mechanism is always kept in a proper working temperature range, the service life of electronic components in the pressure release mechanism is prolonged, parts of the heat dissipation mechanism are conveniently connected through the arrangement of the butt joint mechanism, a warning effect can be achieved when the temperature of a main body is detected to be abnormal through the effect of the early warning mechanism, and the structural design convenient to install improves a use effect.

Description

technical field [0001] The invention relates to the field of transformer pressure release, in particular to a cooling device with an early warning function used in the pressure release process of an oil-immersed transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, reactors, anti-interference transformers, lightning protection Transformers, box-type transformer test transformers, corner tran...
