Is the 269 electric knots sold on Pinduoduo really as power efficient as they introduced?

All power savers are fake! First of all, power is proportional to energy consumption, that is, the greater the power, the greater the energy consumption; The second is the power factor.

Only industrial ultra-high-power capacitive loads (mainly referring to industrial motors) will reduce the power factor due to reactive power consumption, so high-power industrial electricity mostly uses capacitor cabinets for reactive power compensation.

The civilian 220-volt AC usually defaults to the power factor, so there is no need to compensate; Third, and most importantly, buying a power saver is to pay an IQ tax.

Inside the economizer is a capacitor, plus a housing with an indicator light. This thing is a time bomb, which not only consumes electricity, but also has the potential to break down and cause a fire; Fourth, from the perspective of electrical technology, the principle of power saving is to save electricity, reasonable equipment support, and off-peak electricity consumption! There is really a power-saving technology, the country has long invested, what else does the country build, what wind energy and nuclear power, and it is the turn to get these ** fools,

These are two things:

One is a fake "power saving", which may be a reduction in voltage, and you use a certain appliance (such as a rice cooker) to look like the meter is slowing down, but cooking a meal does not save the number of degrees of electricity.

Most of these so-called power savers are fake, don't pay the IQ tax. The real power saving is to pay attention to turning off the lights in daily life, turning off some infrequently used electrical appliances and unplugging them.

This situation must be deceiving, because it is difficult to save electricity and save electricity, although it may have a certain effect, but it is not as exaggerated as they advertise.

Hello! The so-called power saver is a lie, and it is generally a low-voltage way to achieve power saving, which may lead to the failure of the appliance to operate perfectly.

For families, because the main electrical appliances are air conditioners and refrigerators, the energy efficiency ratio stipulated by the state is an indicator of electricity saving. You can't achieve obvious results with a power saver, it's basically fooling you. What can save 50% of electricity is too deceiving.

And none of them dare to label the production plant, it is a three-no product, and the people are ignorant.

Dear, hello, the power-saving artifact sold on Pinduoduo cannot save electricity, because the so-called "power-saving artifact" only knows that the installed capacitors can only play a role in improving the power factor, and have a certain effect on protecting voltage and suppressing harmonics, but it has power itself, and Qi Shanchang will consume electricity when used, so it will increase power consumption. If the high-quality capacitor is used, long-term use may increase the line loss of the original line and bring fire hazards.

Hello dear dear, I'm happy to answer for you: can the power-saving artifact sold on Pinduoduo really save electricity, the answer is: don't save the power of the group, oh kiss Pinduoduo on the top of the energy-saving power-saving king is not very good, nor power-saving, sometimes buy back and carry it back for a few days will be broken, his quality is very bad, it seems to be fake and shoddy products, ** cheaper, but the quality is not good at all, the energy-saving power-saving king bought back is not power-saving at all, useless, are all deceitful, fake**cheap, No good goods economizer is essentially a capacitor, with a capacity of 1 10 microfarads.

It seems that saving electricity can indeed save electricity, but it is not. Because the Hongsheng meter of an ordinary family will not include the reactive power! The power supply bureau only assesses the active power of household electricity, and only installs active energy meters.

In other words, no matter how much reactive power you generate, the meter will not be billed, and the power supply bureau will not fine you. So, saving electricity is useless in the first place. Considering with scientific knowledge thinking, electrical equipment must have current and voltage to consume electrical energy in order to work.

The metering meter of electric energy consumption is calculated and measured by the magnitude, time and length of the current flowing through the circuit. The so-called power saving king cannot save electricity, and there is no scientific basis, on the contrary, it may increase power consumption when connected to the circuit.

It's useless. On the contrary, there are safety risks. The main devoid of the power saver is composed of capacitors, thyristors, coils and insurance.

Capacitors are mainly used for reactive power compensation for motor loads such as refrigerators and air conditioners. For the user, it is metered that there is a utility of electricity, so it will not save power. In circuits, loads can generally be divided into:

Purely resistive (e.g. light bulb), inductive (e.g. electric motor). The inductance and capacitor in parallel can cancel each other out. In general, power consumption due to increased inductance or capacitance is useless.

In the circuit design hole meter, the reactivity of the loop should be minimized, so that the load behaves as pure resistance, which is commonly known as impedance matching. This stabilizes the circuit and saves power.
