Abstract
The detector set includes voltage comparator composed of voltage transformer, time-base circuit. Primary coil of voltage transformer is connected to load and relay in series. Through rectification circuit and divider circuit, secondary coil of voltage transformer is connected to the input end of the time-base circuit, which is wired in monostable circuit. Normally closed contact of relay is connected to primary coil of voltage transformer, and load in series. When electrical appliances are in stand by state, the disclosed detector set cuts off power source of appliances. The invention is applicable to air conditionner, computers and TV set to detect their stand by state.
Description
Technical field the invention belongs to electronic technology in the control Application for Field.
Before background technology the invention applying date, air-conditioning, computer, TV etc. exist the drawback of standby power consumption owing to do not have standby powered-down function.
Summary of the invention purpose of the present invention just is to provide a kind of standby no-power-comuption detecting device.
The invention solves the technical scheme that its technical matters adopts: comprise the voltage comparator pick-up unit; Voltage comparator is made up of voltage transformer (VT), time base circuit, voltage transformer (VT) primary coil and load and relay polyphone, the secondary coil of voltage transformer (VT) is connected with the time base circuit input end by rectification circuit, bleeder circuit, time base circuit is connected into monostable volt circuit, and the normally closed contact of relay and voltage transformer (VT) primary coil and load are in series.Described voltage comparator is made up of voltage transformer (VT), time base circuit, voltage transformer (VT) primary coil and load and relay polyphone, the secondary coil of voltage transformer (VT) is connected with the time base circuit input end by rectification circuit, bleeder circuit, time base circuit is connected into monostable volt circuit, and the normally closed contact of relay and voltage transformer (VT) primary coil and load are in series.
The beneficial effect of the invention is: the invention detects as readiness no power consumption for air-conditioning, computer, TV etc. and puts.When detecting the electric appliance standby state, cut off appliances power source, realize readiness no power consumption, save the purpose of electric resources.
