Flexible full-protection-based explosion-proof transformer for graphite purification workshop

Abstract

The invention discloses a flexible full-protection-based explosion-proof transformer for a graphite purification workshop. The flexible full-protection-based explosion-proof transformer comprises a temperature control type inert gas pressure supplementing device, a piston type manual vacuumizing mechanism, a double-one-way valve type manual air inlet control mechanism and a closed vacuum transformer box body. The invention belongs to the technical field of transformer protection, and particularly relates to an explosion-proof transformer for a graphite purification workshop based on flexible full protection. The invention provides a technical means of dissipating heat through a metal shell and isolating combustion through a sealed vacuum chamber (a chamber with a certain vacuum degree instead of absolute vacuum), and creatively provides a closed vacuum transformer box body and a temperature control type inert gas pressure supplementing device, flame retardance is carried out through the vacuum chamber, and the temperature control type inert gas pressure supplementing device is arranged in the vacuum chamber. Physical impact is resisted through the strength of the shell, when combustion and explosion occur, by means of releasing inert gas, not only can the internal and external pressure difference be balanced and the box body be prevented from deforming, but also the flame-retardant and fire-extinguishing capacity can be further improved by means of filling the inert gas.

Description

technical field [0001] The invention belongs to the technical field of transformer protection, in particular to an explosion-proof transformer for a graphite purification workshop based on flexible full protection. Background technique [0002] When purifying graphite, kerosene or petroleum is often used as a collector, and kerosene and petroleum are both flammable and explosive substances. Therefore, graphite proposes that the transformer in the workshop needs to have an explosion-proof function, and can be used in the event of explosion, combustion and other dangers in the workshop. Flame retardant effect to prevent secondary damage. [0003] Under normal circumstances, the explosion-proof flame retardant of a transformer is to coat a layer of heat-insulating flame-retardant material on the outside of the transformer casing, but this method is not conducive to heat dissipation, and the flame-retardant effect is not ideal; therefore, the present invention takes the lead in ...

Problems solved by technology

[0003] In general, the explosion-proof and flame-retardant of transformers is to wrap a layer of heat-insulating and flame-retardant materials on the outside of the transformer shell, but this method is not conducive to heat dissipation, and the flame-retardant effect is not ideal; therefore, the present invention is the first to propose a An explosion-proof transformer for graphite purification workshop based on vacuum insulation and flexible full protection
