invenzione avente per TITOLO: invention having as TITLE:
Generatore ad alta tensione per assistenza elettrostatica alla stampa e airaccopptamcnio di film, con eliminazione del fenomeno di scariche parassite pericolose In atmosfere esplosive e metodo di produzione del dispositivo di emissione High voltage generator for electrostatic assistance to printing and air coupling of film, with elimination of the phenomenon of dangerous parasitic discharges in explosive atmospheres and method of production of the emission device
Descrizione; Description;
La scarica elettrica in gas avviene per "scarica" rapida, dovuta alla fase di resistenza negativa, delle energie accumulate nei sistema ogni qual volta il campo elettrico supera la rigidità dielettrica del gas stesso. The electric discharge in gas occurs by rapid "discharge", due to the negative resistance phase, of the energies accumulated in the system whenever the electric field exceeds the dielectric strength of the gas itself.
La scarica diventa pericolosa in ambienti saturi di vapori infiammabili solo se: Discharge becomes dangerous in environments saturated with flammable vapors only if:
1) la propria energia supera un valore limite tipico delle miscele esplosive: 1) its energy exceeds a limit value typical of explosive mixtures:
2) le correnti sono tanto elevate e continue da produrre riscaldamento dei catodi tale da superare la temperatura di fiamma delle miscele esplosive. 2) the currents are so high and continuous as to produce heating of the cathodes such as to exceed the flame temperature of the explosive mixtures.
li nostro generatore opera su tre elementi; Our generator operates on three elements;
J )l -imita l'energia accumulata net sistema: limita la capacità elettriche del sistema stesso e pone per ogni elemento emettitore degli dementi passivi di protezione 2)1 imita la velocità di aumento della corrente: pone altri elementi passivi sul percorso delta corrente in modo da rallentare la velocità di aumento dì corrente, si da poter intervenire per tempo per disattivare Π sistema in caso di accenno di scarica. J) l - limits the energy accumulated in the system: it limits the electrical capacity of the system itself and places passive protection elements for each emitter element 2) 1 imitates the current increase speed: places other passive elements on the delta current path in in order to slow down the rate of increase of current, it is possible to intervene in time to deactivate the system in the event of a hint of discharge.
3)blocca l'alimentazione dell’apparecchiatura in tempi mollo brevi, sulla base dei valori di tensione e correnti istantanei, in modo da limitare gli effeti cumulativi. 3) blocks the power supply of the equipment in very short times, based on the instantaneous voltage and current values, in order to limit the cumulative effects.
Per raggiungere alte tensioni continue si fa normalmente uso dì trasformatori e filtri capacitivi o trasformatori e moltiplicatori di tensione; in entrambi i cast sono presemi capacità di sistema che rappresentano un accumulo di energia di sistema. To reach high continuous voltages, use is normally made of transformers and capacitive filters or voltage transformers and multipliers; in both casts system capacities are presemi that represent a system energy storage.
Esìstono inoltre capacità parassite intrinseche nei componenti (cavi.schede.ecc) che si sommano a quelle di sistema che contribuiscono ad aumentare Γ energia accumulata. There are also intrinsic parasitic capacities in the components (cables, boards, etc.) which are added to those of the system which contribute to increasing the stored energy.
Le normative sulla sicurezza intrinseca prima citate, forniscono valori massimi di energia della scarica al di soto dei quali l'accensione della miscela non può avvenire; sappiamo inoltre che una resistenza posta sul percorso della corrente limita notevolmente l'energia che il sistema può fornire alia scarica: Se normative stesse forniscono valori dì riferimento per varie tensioni, capacità, resistenze. The aforementioned intrinsic safety regulations provide maximum discharge energy values below which ignition of the mixture cannot take place; we also know that a resistance placed on the path of the current considerably limits the energy that the system can supply to the discharge: If standards themselves provide reference values for various voltages, capacities, resistances.
Pertanto la soluzione del problema è stata : Therefore the solution to the problem was:
I) limitare le capacità elettrica del sistema aumentando la frequenza di lavoro del trasformatore , utilizzando trasformatori in alta frequenza e filtri capacitivi di basso valore I) limit the electrical capacities of the system by increasing the working frequency of the transformer, using high frequency transformers and low value capacitive filters
