Abstract

Przedmiotem wynalazku jest układ do pomiaru rezystancji izolacji doziemnej na szynach rozdzielnicy niskiego napięcia prądu stałego mający zastosowanie w kontroli bezpieczeństwa elektroenergetycznego statku. Układ charakteryzuje się tym, że zawiera pomiarowy przełącznik sekcyjny (1), moduł pomiarowo-obliczeniowy (101), moduł alarmów i regulacji parametrów (102), początkowy rezystor RO, pierwszy rezystor R1, drugi rezystor R2, trzeci rezystor Ru, przy czym początkowy rezystor Ro i drugi rezystor R2 są połączone szeregowo z pomiarowym przełącznikiem sekcyjnym (1). Początkowy rezystor Ro i pierwszy rezystor R1, drugi rezystor R2 i trzeci rezystor Ru są połączone z modułem pomiarowo-obliczeniowym (101), który jest połączony z modułem alarmów i regulacji parametrów (102), pomiarowy przełącznik sekcyjny (1) jest połączony z jednym biegunem dodatnim szyny rozdzielnicy niskiego napięcia P+ prądu stałego oraz z jednym biegunem ujemnym szyny rozdzielnicy niskiego napięcia P- prądu stałego. Zastosowanie układu zapewnia bezpieczne działanie sieci niskiego napięcia prądu stałego statków o zasilaniu hybrydowym, zapobiega awariom zagrażającym bezpieczeństwu statków spowodowanym uszkodzeniami izolacji sieci niskiego napięcia prądu stałego. Układ może być realizowany zarówno przez obwody analogowe jak i poprzez zastosowanie inteligentnych obwodów cyfrowych współpracujących z CPU.The subject of the invention is a system for measuring ground insulation resistance on low-voltage direct current switchgear busbars used in the ship's power security control. The system is characterized by the fact that it includes a section measuring switch (1), a measurement and calculation module (101), an alarm and parameter control module (102), an initial RO resistor, a first resistor R1, a second resistor R2, a third resistor Ru, with the initial resistor Ro and the second resistor R2 are connected in series with the measuring section switch (1). The initial resistor Ro and the first resistor R1, the second resistor R2 and the third resistor Ru are connected to the measuring and calculation module (101), which is connected to the alarm and parameter control module (102), the measuring section switch (1) is connected to one pole positive low voltage switchgear busbar P + DC and with one negative pole low voltage switchgear busbar P- DC. The application of the system ensures safe operation of the low-voltage DC network of ships with hybrid power supply, prevents failures threatening the safety of ships caused by damage to the insulation of the low-voltage DC network. The system can be implemented both by analogue circuits and by using intelligent digital circuits cooperating with the CPU.
