Abstract

KONTROLNIK OTPORA IZOLOVANOSTI PREMA MASI, naznačen time, što su dva otporanika (R1, R2) redno vezana na krajeve izvora postrojenja (G) čiji se otpor izolovanosti prema masi kontroliše, a izmedju srednje tačke ovih otpornika i mase postavljen potenciometar R3 čija se srednja tačka vodi na ulaze operacionih pojačavača vezanih kao Šmitova okidna kola (A1,A2,R8-R13), kod kojih su konkurentni ulazi na odgovarajuće polarisanim otporničkim razdelnicama (r4, R5; R6, R7), a izlazi, preko logičkog ili kola (V1, V2, R14, R15) vezani na tranzistor (V6) u čijem je izlasnom kolu namotaj relea (K1). Prijava sadrži još 2 patentna zahteva.INSULATION RESISTANCE CONTROLLER TO GROUND, characterized in that two resistors (R1, R2) are connected in series to the ends of the source of the plant (G) whose insulation resistance to ground is controlled, and between the midpoint of these resistors and ground placed potentiometer R3 whose midpoint leads to the inputs of operational amplifiers connected as Schmidt trigger circuits (A1, A2, R8-R13), where the inputs are on the correspondingly polarized resistor junctions (r4, R5; R6, R7), and the outputs, via a logic or circuit (V1, V2, R14, R15) connected to the transistor (V6) in whose output circuit is the relay winding (K1). The application contains 2 more patent claims.
