Now it is 380" means that the company is now using 380V three-phase low-voltage power supply.

There are many kinds of 380V meters: 10 (40) A, 15 (60) A, 30 (100) A, and the current that can be used is different.

Now your company uses a set and a set of air conditioners, then there is, even if you don't count your other equipment, here has exceeded 100kw, you can no longer use low-voltage power supply, must use 10kv high-voltage power supply.

For specific matters, it is best to consult the power department and apply.

380 is now commonly used low-voltage electric voltage! You all know that there is 630kw, why don't you know the meaning of 380! 630kw and its current is more than 1000 amperes!

Why did you come to a 380 amp! If you really want at least 10 thousand volts of high-voltage power supply at 630kw as you said, and you need to be equipped with a transformer above 630kva, maybe you are now in this configuration, and you may want to increase the capacity of the transformer! Or to increase the line, in fact, the specific need to ask professionals to measure on the spot to draw conclusions!

The way you calculate is not right, there is no 630kw you calculate the comprehensive to multiply the need coefficient and the simultaneous coefficient.

So the final power is not that big (the specific algorithm is combined with other data, for example, is your air conditioner three-in-one?) ）

As for whether to change the line or add a transformer to supply 10kV, as long as you coordinate with the power supply bureau.

If it is possible for your unit to continue to develop, then it is better to apply for 10kV power supply to add a transformer room.

If it doesn't develop too much, try to apply for a line change.

The cost of engaging in a 10kv power distribution room is also quite large, hehe, I am a power design unit).

Electricity consumption (kW) Power (kW) Usage time (hours).

The formula for calculating the electricity consumption is: w = uit (where w is the electricity consumption, u is the rated voltage, i is the rated current, t is the working time, suitable for any circuit); w = p*t (where w is the power consumption, p is the rated power, t is the working time, and the rated power is indicated on the nameplate of the equipment).

Electricity calculation formulaThe calculation formula for electricity consumption is: 1W=UIT (where W is the electricity consumption, U is the rated voltage, I is the rated current, T is the working time, suitable for any circuit) 2W=P*T (where W is the power consumption, P is the rated power, T is the working time, and the rated power is indicated on the nameplate of the equipment).

1 kWh 1 kWh, a power 1 kWh of electricity consumed by an appliance with a power of 1 kWh of continuous operation for 1 hour. Calculate the public and closed combustion type as: electricity consumption (kWh) Power (kW) Use time (hours) such as:

1 hour electricity consumption (kWh) Power (kW) 1 (hour) 1 kWh = 1000w * 1 hour = 1 kWh.

The amount of electricity indicates the amount of charge carried by an object, which is represented by the symbol Q in Coulombs.

The formula for calculating the amount of electricity is i=q t, q=i* is the current, the unit ampere (a), t is the time, and the unit second (s). <

Sail or tease electricity load power Electricity time, the unit of electricity consumption is kWh, kilowatt small group of mountains, that is, one kilowatt of electricity.

For example, if the load is 5kw and the electricity is used for one hour, it is used to sell 5kwh and 5 kWh of electricity in 1 (hour) state.

The load is 100W, and the electricity is used for 10 hours, which is 10 (hours) 1kWh, 1 kWh.

To calculate your electricity usage, you can follow these steps:

1.Get the power of an appliance: Check the label, instruction manual, or product specification sheet on the appliance to find the appliance's power rating. It is usually expressed in watts (w).

2.Calculate usage time: Determine the actual usage time of the appliance. You can record the time you spend using the appliance each day and convert it into hours as a cluster, or estimate the time spent on a weekly or monthly basis.

3.Calculate the energy consumption of an electrical appliance: Calculate the energy consumption of an appliance using the following formula:

Power consumption (kWh) = Power (watts) Use time (hours) 1000

Where power is measured in watts and usage time is measured in hours, divided by 1000 to convert the result to kilowatt-hours.

4.Repeat the above steps: Do the same for other appliances.

5.Cumulative Energy Consumption: The energy consumption values of all appliances are added up to get the total electricity consumption.

Note that this is a basic calculation for a rough estimate of electricity consumption. The actual situation may be affected by factors such as the efficiency of the appliance, changes in the time of use, and the waste of energy sources. If you want to get an accurate picture of your electricity usage, you can also consider using an energy meter or energy monitoring device.

Electricity usage is one of the most common things in our daily life, and how to calculate electricity usage can generally be calculated with tools and formulas. Specifically, when a home or business uses electricity, it is common to record the amount of electricity used through the electricity meter, and this process does not require much thought on our part.

Basically, we only need to see the change in the value on the meter number on the meter to know how much electricity is being consumed. The meter will show the current degree and the usage of electricity, and the number of degrees on the meter will change every second. The sum of these changes is the current electricity consumption.

It is important to note here that there may be differences in the digital readings of different types of meters, so we need to understand and compare the digital changes of different types of meters.

In addition, when calculating the amount of electricity, we also need to consider the magnitude of voltage and current, because the magnitude of electrical energy is determined by the magnitude of voltage and current. When calculating the amount of electricity, the formula of multiplying power by time is generally used, i.e., power = power time. This formula is very effective when calculating the use of electricity over a certain period of time, helping us to evaluate our energy usage in order to contribute more in terms of electricity savings.

Finally, there are some simple ways we can reduce our electricity consumption in our daily lives, such as turning off unnecessary appliances and equipment, using energy-efficient appliances, and making the most of natural lighting.

In summary, we can calculate the amount of electricity used by multiplying the meter readings and power by the time, which applies to both home and business premises. At the same time, we can take some simple measures to save electricity and reduce electricity consumption, so as to maximize the benefits of energy consumption. <>

The method of calculating electricity consumption depends mainly on the specific context you are referring to. In general, calculating electricity consumption involves the following aspects:

1.Power of appliances: First, you need to know the power of each appliance that uses electricity. Power is usually indicated in watts (W) on appliances or in product manuals. For example, the power of a light bulb is usually given in watts.

3.Calculation of electricity consumption: Electricity consumption can be calculated by the following formula: electricity consumption (kilowatt-hours) = power (kilowatts) and usage time (hours).

Let's take an example: Suppose you use a table lamp with a power of 100 watts for 5 hours a day, calculate the electricity consumption of the lamp. The power is first converted into kilowatts, i.e., kilowatts.

Then multiply the power by the time used, i.e. kW 5 hours = kWh. This means that the lamp consumes kilowatt-hours of electricity per day.

Note that this is just a simple calculation example, and the actual situation may be more complex. In actual use, you also need to take into account the power consumption of different electrical appliances, the late billing mode of electricity pricing, and seasonal factors.

If you want to get an accurate picture of your electricity usage, the best way to bridge the road is to check your meter or consult your local electricity provider, who can provide detailed electricity usage data and billing information. <>

Calculated according to the formula: time = 1000 power, electricity consumption = 1 time. Such as:

The power of an electrical appliance is 2000w, according to the formula: time = 1000 power, find the time 1000 2000 = hours, that is, one kilowatt-hour of electricity. Then, according to the formula, the hourly electricity consumption = 1 time is dismantled, and the hourly electricity consumption is 1 kWh.

The power consumption is related to the power of the electrical appliances purchased from the stove, and the electricity consumption of 1 kilowatt-hour is usually 1000 watts of electrical appliances, so it is easier to calculate the power consumption according to the formula. The electricity cost incurred is easy to calculate.

The rated power of the electrical appliance is the power of the electrical appliance when it is working normally, and the value is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the appliance is greater than the rated power, the appliance may be damaged; If the actual power is less than the rated power, the electrical appliance cannot operate normally.

Under normal operating conditions, the output power of the power equipment or the input power of the energy-consuming equipment is the power that the machine produced by the factory can achieve during normal operation, therefore, the rated power of the machine is certain.
