Abstract
This invention refers to an explosion-resisting frequency converter, which contains frequency conversion circuit assembly in explosion resisting casing composed of explosion cavity, cover, radiation fins and bottom cover, protective hood with ventilation holes and fan, water cooling radiator set below bottom cover of radiation fins and connected with water channel, cable leading out device set on lower part of explosion resisting cavity. Said invention has reliable explosion resisting cooling effect.
Description
Technical field
The present invention relates to a kind of hazardous areas such as inflammable, explosive that are used for, the explosion-proof frequency converter of control motor speed.
Background technology
At present, the available use of frequency conversion that does not have explosion prevention function in hazardous area such as inflammable, explosive, generally be the common frequency converter that makes no explosion prevention function away from hazardous area such as inflammable, explosive, be connected with motor in the hazardous area by long lead, with the control motor speed.Like this, the installation trouble is used inconvenience, needs two to run in case break down, and in addition, the explosion-proof place of former right and wrong becomes explosion-proof place, and then common frequency converter need be moved away from needs explosion-proof place, and effort, time-consuming is brought very big influence to work.
Summary of the invention
The objective of the invention is for frequency converter can be used in hazardous area such as inflammable, explosive, site examining and repairing, inquiry provide a kind of frequency converter with explosion prevention function.
Technical scheme of the present invention is: a kind of explosion-proof frequency converter; be characterized in; the frequency changer circuit assembly places by explosion-proof cavity; case lid; in the explosion-proof tank that the fin bottom is formed; fin is fixed on the fin bottom; heater element on the frequency changer circuit assembly is connected with the fin bottom; by the fin bottom to heat sink conducts heat; protection fin and place on the fin bottom as the protective cover of the usefulness of frequency converter installation; the protective cover top is equipped with explosion-proof radiator fan; Hot-air fan; the protective cover below is equipped with ventilation hole; fin bottom bottom is equipped with water-filled radiator; the water channel of itself and fin bottom links, and explosion-proof cavity bottom is equipped with explosion-proof cable and draws introducing device.The water channel of described fin bottom can with external water pipe UNICOM.
Effect of the present invention is: because the frequency changer circuit assembly places in the explosion-proof tank of being made up of explosion-proof cavity, case lid, fin bottom, explosion-proof cavity bottom is equipped with the cable that meets requirement of explosion proof and draws introducing device, therefore, explosion-proof effect with function admirable, the utility model adopts cooling system air-cooled and that water-cooled combines, makes this frequency converter reach extraordinary cooling effect.
Description of drawings
Fig. 1 is the structural representation of explosion-proof frequency converter;
Embodiment
The embodiment of the invention is described further in conjunction with the accompanying drawings.
According to shown in Figure 1; a kind of explosion-proof frequency converter; be characterized in; frequency changer circuit assembly 12 places by explosion-proof cavity 13; case lid 9; in the explosion-proof tank that fin bottom 1 is formed; fin 2 is fixed on the fin bottom 3; fin 2 also can be made one with fin bottom 1; heater element 4 on the frequency changer circuit assembly 12 is connected with fin bottom 1; by fin bottom 1 to fin 2 heat conduction; described heater element can be the high power contravariant module; rectifier cell; voltage stabilizing element etc.; protection fin and place on the fin bottom 1 as the protective cover 3 of the usefulness of frequency converter installation; protective cover 3 tops are equipped with explosion-proof radiator fan 14, and protective cover 3 belows are equipped with ventilation hole 5, and fin bottom 1 bottom is equipped with water-filled radiator 6; the water channel 7 of itself and fin bottom 1 links water channel 7 and external water pipe UNICOM.Be equipped with the observation window 11 that meets requirement of explosion proof on described case lid 9, observation window 11 belows are equipped with the adjusting button 10 that is used for parameter setting that meets requirement of explosion proof.Be equipped with the cable that meets requirement of explosion proof in described explosion-proof cavity 13 bottoms and draw introducing device 8, its seal approach is with the close solar or lunar halo sealing of rubber.Explosion-proof cavity 13 and case lid 9 and and fin bottom 1 between also can be equipped with sealing strip 15.Fan in the utility model adopts the intrinsic safe explosion-proof type.The utility model adopts cooling system air-cooled and that water-cooled combines, as with air-cooled, arrived a certain design temperature, but temperature continues rising, then connects water-cooling system automatically, and is for example air-cooled to 25 ℃ of startings, reaches good cooling effect to 45 ℃ of starting water-cooleds.
