2, whether require safety utilization of electric power in the daily life, it is charged to measure circuit.And present insert row can't be prevented trouble before it happens according to just aspect voltage, having indication, power not to have suggestive display unit when soon reaching rated power.

The utility model content

The purpose of the utility model is exactly in order to address the above problem, and provides a kind of survey electric formula insert row, and it has rational in infrastructure, the advantage of safety.

To achieve these goals, the utility model adopts following technical scheme:

The electric formula insert row of a kind of survey, it comprises master switch, indicator light is characterized in that, on insert row, sets up controller, display unit, data acquisition unit, actuator, described display unit, control button, actuator is connected with controller respectively.

Said controller is the STC single-chip microcomputer.

Said data acquisition unit comprises current sensor and AD conversion chip, and said current sensor transforms chip through AD and is connected with controller.

Said display unit is a LCD display.

Said control button is four separate button, is respectively the rise button, down button, switching push button, confirming button.

The electric formula insert row of said survey also is provided with resetting means, and said resetting means comprises the reset key that is provided with.Said reset key is connected with controller.

Described actuator comprises electromagnetic relay, and the contact of said electromagnetic relay is connected on before each jack circuit on the circuit, and the coil of said electromagnetic relay is connected with controller.

Said display unit, control button are located on the insert row front panel.

When line attachment, measure the maximum power that current circuit can carry; Confirm four electrical power that button is regulated restriction through raising, reduce to switch; Show simultaneously and to realtime power, above-mentioned 3 electrical power are shown through the LCD display that is connected on the STC single-chip microcomputer.When the electrical appliance line attachment; Measure the gross power that current electrical appliance is pegged graft; Through comparing with the power-limiting set point, if less than then inserting automatically, when greater than the time then cut off the last electrical appliance that inserts through the electromagnetic relay before being connected on each jack circuit automatically.

People are when concrete the use, and the described insert row of the utility model provides hommization to design, and can in people's electricity consumption, excess load be taken measures automatically, ensures the safety of electricity consumption.

The beneficial effect of the utility model:

Output detects and avoids the excessive safety that causes tripping operation, short circuit, serious words may breaking out of fire to jeopardize the household easily to the power of insert row.

On the basis of daily civilian insert row, transform, make it have the function of mensuration, demonstration, qualification power.

So just when power soon reaches rated power, remind and to avoid danger.Electrical power is shown that with display screen hommization more is fit to all kinds of crowds and uses, conveniently reach reasonable safety utilization of electric power.Understanding according to investigations at present just has product aspect measuring voltage, so market prospects are very big.
