Abstract
Inventia se refera la un dispozitiv tranzistorizat de comanda, la distanta, cu siguranta intrinseca si pozitiva pentru contactoare si instalatii de automatizare, destinate exploatarilor ,de carbune, dispozitiv ce realizeaza protectia la scaderea rezistentei de izolatie si a rezistentei circuitului exterior, precum si comanda de anclansare si declansare, functiuni relaizate prin compararea parametrilor circuitului exterior cu circuitul interior, facînd ca numai la functionarea corecta a celor doua circuite de masura, simultaneitatea în furnizarea informatiei si aparitia comenzii de anclansare din circuitul exterior sa apara comanda de cuplare catre contactor sau instalatia de automatizare.The invention relates to a remote, intrinsically safe positive transistor device for contactors and automation installations designed for exploitation, coal, a device for protection against loss of insulation resistance and resistance of the external circuit, as well as a command for switching and triggering, functions correlated by comparing the parameters of the external circuit with the internal circuit, making only the correct operation of the two measuring circuits, the simultaneity in the supply of the information and the occurrence of the clutch control in the outer circuit, the coupling command to the contactor or the automation.
