Abstract

SE REFIERE A UN DETONADOR QUE INCLUYE A UNA FUENTE DE ENERGIA, UN ELEMENTO INICIADOR, UN CIRCUITO DISPARADOR PARA CAUSAR UNA DESCARGA DE ENERGIA, DESDE LA FUENTE DE ENERGIA HASTA EL ELEMENTO INICIADOR Y UN ELEMENTO DE CIRCUITO CON UN VALOR DE RESISTENCIA, CONECTADO EN SERIE CON EL CIRCUITO DISPARADOR Y CON EL ELEMENTO INICIADOR. ASI TAMBIEN SE DESCRIBE UN METODO PARA AJUSTAR EL VOLTAJE DE NO DISPARO DE UN DETONADOR, MIENTRAS SE MANTIENE LA DIFERENCIA ENTRE EL VOLTAJE DE NO DISPARO Y UN VOLTAJE DE PRUEBA SEGURO DENTRO DE UN RANGO DE SEGURIDAD, EL METODO COMPRENDE EL PASO DE INCLUIR UN ELEMENTO DEL CIRCUITO CON UN VALOR DE RESISTENCIA , EN SERIE CON UN ELEMENTO INICIADOR EN EL DETONADOR Y CON UN CIRCUITO DISPARADOR QUE SE CONECTA CON UNA FUENTE DE ENERGIA, LA QUE SE USA PARA DISPARAR AL ELEMENTO INICIADORREFERS TO A DETONATOR INCLUDING AN ENERGY SOURCE, AN INITIATING ELEMENT, A TRIGGER CIRCUIT TO CAUSE AN ENERGY DISCHARGE, FROM THE ENERGY SOURCE TO THE INITIATING ELEMENT AND A CIRCUIT ELEMENT WITH A RESISTANCE VALUE, CONNECTED IN SERIES WITH THE TRIGGER CIRCUIT AND WITH THE INITIATING ELEMENT. IT ALSO DESCRIBES A METHOD TO ADJUST THE NON-FIRE VOLTAGE OF A DETONATOR, WHILE MAINTAINING THE DIFFERENCE BETWEEN NON-TRIP VOLTAGE AND A SAFE TEST VOLTAGE WITHIN A SAFETY RANGE, THE METHOD INCLUDES THE STEP OF OF THE CIRCUIT WITH A RESISTANCE VALUE, IN SERIES WITH AN INITIATING ELEMENT IN THE DETONATOR AND WITH A TRIPPING CIRCUIT THAT IS CONNECTED WITH AN ENERGY SOURCE, WHICH IS USED TO TRIP THE INITIATOR ELEMENT
