Local high-temperature optical change self-reminding type transformer

Abstract

The invention discloses a local high-temperature optical change self-reminding type transformer, and belongs to the field of transformers. According to the local high-temperature optical change self-reminding type transformer, through the arrangement of a plurality of optical change mushroom balls, when local heat at cooling fins is high, the heat enters optical change hemispheres along magnetic attraction heat conduction rods, and a high heat conduction gas is heated to expand; and an air support spacer is pushed to expand towards one side of a ball containing groove, and the expanded air support spacer pulls the opening part of an elastic pipe so that fluorescent color balls fall into the optical change cavity and are longitudinally distributed, the surface of the optical change mushroom ball near the position where the heat is locally higher presents a colored optical spot phenomenon, and therefore the effect of reminding workers is achieved. Working personnel can maintain uneven local heat distribution in time, and potential safety hazards are reduced. And in addition, after being heated, an external pressure air core gradually expands to extrude a fluorescent liquid so that the liquid level rises, the light emitting range of the fluorescent color balls is effectively enlarged, and the reminding effect on the workers is remarkably improved.

Description

technical field [0001] The invention relates to the field of transformers, more specifically, to a local high-temperature light-changing self-reminder type 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). Transformer cooling refers to dissipating the heat generated by the running transformer through certain methods. When the transformer is running, the heat generated by the loss of the winding and core must be dissipated in time to avoid insulation damage caused by overheating. For small-capacity transformers, the ratio of the outer surface area to the volume of the transformer is relatively large, and a self-cooling method can be used to dissipate heat through radiation and natural convection. The self-cooling method is suitable for indoor small transformers. In order to prevent fires, dry type is ...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a local high-temperature light-changing self-reminder type transformer. Through the setting of multiple light-changing mushroom balls, when the local heat at the heat dissipation scales is high, the heat will flow along the The magnetic heat-conducting rod enters the light-changing hemisphere, causing the high thermal conductivity gas to expand when heated, pushing the air-supported spacer to expand toward the side of the ball-holding groove, and the expanded air-supported spacer pulls the mouth of the elastic tube to make multiple fluorescent color balls fall Into the light-variable cavity and presents a longitudinal distribution, so that the surface of the light-variable mushroom ball near the local high heat presents a color light spot phenomenon, so as to realize the reminder function to the staff, so that the staff can timely correct the local uneven heat distribution In addition, after being heated, the external pressure air core gradually expands and squeezes the fluorescent liquid, making the liquid level rise, effectively increasing the luminous range of the fluorescent color ball, and significantly improving the reminder effect for the staff
