Abstract
The utility model discloses an electronic-type electrical energy measuring power plug. Besides connecting to a power supply, the plug can also display voltage, electric current, power consumption, and power consumption, and also has the function of memory. The utility model is arranged in an enclosure for the power plug; an inductor is arranged on one conductor incoming from a pin; an outgoing line of the inductor is connected to a rectifier; an outgoing line of the rectifier is connected to a power measuring chip; the chip is connected with a control knob. A chip circuit is electrically connected with a display through the control knob. An electric impulse indicator light is connected between the rectifier and the chip. The power plug can display and measure power consumption of an electric appliance conveniently.
Description
One, technical field: the utility model is established and a kind of electric elements, particularly a kind of attaching plug.
Two, background technology: existing attaching plug has various styles, but all is to have only pin and lead, is inserted into and plays energized on the socket, does not have other functions in addition.
Three, summary of the invention: the purpose of this utility model provides a kind of electronic metering attaching plug, and it can demonstrate the parameter such as voltage, electric current, electrical appliance power, power consumption of electricity consumption.Its technical scheme is: in the attaching plug shell, on a lead of being introduced by pin inductor is housed, is connected to bridge rectifier on the inductor lead-out wire, the outlet of rectifier connects electric computation chip, be connected with control knob on the chip, chip circuit is connected with display through control knob again.Be connected with at rectifier and chip chamber and use the electric pulse indicator light.
This electronic metering attaching plug can also demonstrate electricity consumption situations such as electric current, voltage, electric weight, electric power respectively in energized, understand and the electricity consumption of metering separate unit electrical appliance provides very big convenience to people.
Four, description of drawings: Fig. 1 is the electrical block diagram of electronic metering attaching plug.
Embodiment: as shown in Figure 1, in attaching plug shell 4, on a power line of being introduced by pin 9 inductor 2 is housed, is connected to bridge rectifier 3 on the inductor lead-out wire, the outlet that induced current is rectified into behind the direct current by rectifier connects electric computation chip 7.Also be connected with control knob A1, A2, A3 on the chip, A1 is an electric current electric weight change-over switch, and A2 is a nulling button, and A3 is the memory button.Chip circuit electrically connects with display through control knob again.
After the attaching plug energized, power supply indicator 1 is bright, and electric current leads to electrical appliance through pin 9 and lead 5.The induced current that inductor produces enters electric computation chip 7 after bridge rectifier 3 rectifications are direct current, by control knob different electric signals is delivered to LCD 6, demonstrates different parameter values.Electric current electric weight change-over switch A1 can show electric current, voltage, electric weight and power; Nulling button A2 can be with the video data zero clearing, so that from the beginning calculate; Memory button A3 can store video data.This attaching plug can measure the electricity consumption situation of electrical equipment separately, is convenient to enterprise's independent accounts.Simultaneously, it can show electricity consumption quantity intuitively, makes people establish saving consciousness.Not power consumption of attaching plug itself is connected with electric pulse indicator light 8 at rectifier and chip chamber, and it is luminous to glimmer when the plug circuit has load, and it is big more to load, and the frequency of flicker is high more.
This attaching plug can be used for common single-phase household electrical appliances, also can be used for using the equipment of three-phase electricity.Attaching plug has binding post as long as introduce a power lead at attaching plug housing upper conductor in-out end when using on three-phase electricity equipment.Attaching plug is connected on the phase line, can reacts the electricity consumption situation of a phase, connect an attaching plug respectively on each phase line, perhaps the numeral that will show multiply by three, just can obtain the electricity consumption situation of equipment.
