Beschreibung
Zusammenfassung:	The objective of the utility model is to generate high alternating current test current by low power supply direct current. The utility model provides an energy-saving type electric leakage fire hazard detector detection device comprising a power supply (1), an oscillation circuit (2), a current amplification circuit (3) and a power amplifier output circuit (4). The detection device is characterized in that the power amplifier output circuit (4) is connected with a current-boosting circuit (5) which is connected with the power supply (1). Low direct current of a power supply battery can be transformed into test-used high alternating current by the detection device so that test effect can be effectively enhanced, and battery energy can be saved.
