Tillämpningen av APF i sjukhusets kraftdistributionssystem

Som ett sjukhus som tillhandahåller oavbruten strömförsörjning 24 timmar om dygnet har det en enorm efterfrågan på el . Säkerheten i sjukhusets kraftförsörjning är inte bara avgörande för säkerheten för medicinsk personal, utan också av stor betydelse för patienternas liv och hälsa .}

Medical equipment includes various devices with nonlinear impedance characteristics, such as precise computer components and highly sensitive microelectronic devices. These will cause severe harmonic pollution to the power grid. The data accuracy of electrocardiogram machines, defibrillators, electrosurgical devices, etc. is slightly affected, seriously endangering the life safety of Patienter .

Harmonics can also interfere with electromagnetic induction, electrostatic induction and conductive interference networks, affecting information systems. Due to the characteristics of medical services, the hospital information network system must operate stably and continuously without interruption for 7×24 hours. Harmonic pollution often causes errors in codes and programs of medical computers, leading to errors such as operation, data, time, kraschar och oväntade omstart, vilket i slutändan får hela systemet att misslyckas . nätverksförlamning påverkar den normala driften av sjukhuset . Därför är kontrollen av harmonik särskilt viktigt för det medicinska kraftsystemet .}

The harmonic pollution of the power distribution network was effectively controlled by using active filters. Harmonics were effectively filtered out, ensuring the safety of electricity supply for the hospital. The total installed capacity of the active filters was 680A. The collected data results show that after the active filters were put into operation, the power quality of the power distribution system of this hospital has significantly improved. The active filters operated normally and the effect was good, achieving the expected treatment effect. The harmonics on the power grid side were well purified. This not only enabled the hospital to further improve energy conservation and consumption reduction, but also ensured the normal and stable operation of medical equipment. It provided a powerful power distribution guarantee for the hospital to better behandla patienter och tjäna folket .
