Abstract

Przedmiotem wynalazku jest układ formowania/kształtowania sygnału prądowego nadajnika lokalizatora obiektów przewodzących prąd elektryczny, w szczególności instalacji elektrycznych, gazowych oraz wodociągowych i światłowodowych z oplotem przewodzącym w budynkach, pomieszczeniach mieszkalnych, obiektach przemysłowych oraz tych, które są umieszczone w ziemi. Układ ma wejście sterujące amplitudą sygnału prądowego (WESA) połączone z wejściem nieodwracającym różnicowego wzmacniacza operacyjnego (WO) połączonego z zaciskiem zasilacza, którego wyjście połączone jest poprzez piąty rezystor (R5) z bramką pierwszego tranzystora wysokonapięciowego (T1) wyposażonego w radiator (RA). Pomiędzy piąty rezystor (R5) i bramkę pierwszego tranzystora wysokonapięciowego (T1) włączony jest drugi kondensator (C2), którego drugi zacisk połączony jest z masą układu (M), zaś wejście odwiercające różnicowego wzmacniacza operacyjnego (WO) połączone jest z układem próbkującym (UP) połączonym z wejściem sterującym kształtem sygnału prądowego (WESK), z którym połączony jest konwerter napięcia (KU) połączony z zaciskiem zasilacza (ZA). Konwerter napięcia (KU) połączony jest z bramką drugiego tranzystora wysokoprądowego (T2), natomiast wyjście układu próbkującego (UP) włączone jest pomiędzy pierwszy rezystor wysokoprądowy (R1) połączony z masą układu (M) i drugi tranzystor wysokoprądowy (T2) połączony szeregowo przez pierwszy tranzystor wysokonapięciowy (T1) i piątą szybką diodę wysokonapięciową z zaciskiem zasilacza. Ponadto pomiędzy pierwszy rezystor wysokoprądowy (R1) i masę układu (M) a pierwszy tranzystor wysokonapięciowy (T1) i piątą diodę zabezpieczającą włączone jest wejście układu mostkowego czterech szybkich diod wysokonapięciowych (D1, D2, D3, D4), którego wyjście jest wyjściem prądowym układu.The subject of the invention is a system for forming / shaping the current signal of the transmitter of the locator of electrically conductive objects, in particular electrical, gas, water supply and fiber optic installations with conductive braid in buildings, living quarters, industrial facilities and those located in the ground. The system has an input controlling the current signal amplitude (WESA) connected to the non-inverting input of the differential operational amplifier (WO) connected to the power supply terminal, whose output is connected through a fifth resistor (R5) to the gate of the first high-voltage transistor (T1) equipped with a radiator (RA). Between the fifth resistor (R5) and the gate of the first high-voltage transistor (T1) a second capacitor (C2) is connected, whose second terminal is connected to the ground of the system (M), and the drilling hole of the differential operational amplifier (WO) is connected to the sampling system (UP) ) connected to the input controlling the current signal shape (WESK), to which the voltage converter (KU) connected to the power supply terminal (ZA) is connected. The voltage converter (KU) is connected to the gate of the second high-current transistor (T2), while the output of the sampling system (UP) is connected between the first high-current resistor (R1) connected to the ground of the system (M) and the second high-current transistor (T2) connected in series through the first high voltage transistor (T1) and fifth fast high voltage diode with power supply terminal. In addition, between the first high-current resistor (R1) and the ground of the circuit (M) and the first high-voltage transistor (T1) and the fifth protection diode, the bridge circuit input of four high-speed high-voltage diodes (D1, D2, D3, D4) is connected, whose output is the current output of the system .
