Energy-saving Solutions for Enterprise
1、Program Overview
◆Saving energy achieves 10% -70%
◆The enterprises do not need to pay for expense of equipment manufacture and installation.
◆Enterprises only need to pay the saving electricity expense to our company according to the actual quantity of energy saving after the equipments put into operation.
◆According thousands of the projects’ implementation experiences, such projects recover the investments in three or four years. (Equipment service life is 15 years)。
◆Our company will no longer charge the saving electricity expense after recovering the investment.
The significance of the program:
1）、Concentrate on solving problems of energy conservation, make enterprises’ energy-saving work reach new level and take their social responsibility。
2）、Avoid the enterprises reactive power fine of low power factor caused by electric energy using (according to Ministry of Electric Power and Water Resources, State Price Control Bureau establish the " measures of power factor adjustment expense ").
3）、Avoid the high-energy consumption enterprises are implemented differential prices because of the changes of national power regulation.
4）、For the standard-conforming large-scale (saved energy equal 10 thousand tons standard coal or more) energy-saving technological transformation projects, China will reward the enterprises for energy saving which based on the "Financial Incentives Interim Measure for Energy-saving Technological Transformations" established by Ministry of Finance, the National Development and Reform Commission.( Amount of 200 yuan / ton of standard coal).
5）、Equipments recovery period is generally 3-4 years, each period payment equal to the amount of current energy-saving benefits, and equipments service life are 15 years, so enterprises will gain huge energy-saving benefits.

- Q: The relationship between the power supply of the notebook and the battery
- 2, when the laptop turns on the power adapter, and the battery power is low, the charging circuit detects the battery power is lower than the set value, the power adapter will side of the host power supply, while the battery charge. After the charge is restored, it is restored to the power supply state directly from the adapter. Therefore, the relationship between the power supply of the notebook and the battery is that the battery is charged by the power adapter when the battery level is below the set value.
- Q: Can the inverter stop intermittently during operation? If so, how to connect and set up
- One of these terminals is a common terminal, which leads from the common terminal and is connected to the corresponding terminal via the relay contact
- Q: What is the motor series parameter setting of the inverter? If it is with the spindle,
- Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning
- Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- Soft starters and frequency converters are two completely different uses of the product. The frequency converter is used for the need for speed control where the output not only changes the voltage but also changes the frequency; the soft starter is actually a voltage regulator for the motor to start when the output only changes the voltage and does not change the frequency. The frequency converter has all the soft starter functions, but its price is much more expensive than the soft starter, the structure is much more complex. Soft starter (soft starter) is a set of motor soft start, soft stop, light load energy saving and a variety of protection functions in one of the new motor control device, known as the Soft Starter abroad. The softener uses a three-phase anti-parallel thyristor as a voltage regulator, which connects it between the power supply and the motor stator. This circuit, such as three-phase full-bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor gradually increases, the motor gradually accelerates until the thyristor is fully conductive, the motor works at the mechanical characteristics of the rated voltage, smooth start, reduce the starting current and avoid starting the overcurrent trip. When the motor reaches the rated speed, the start-up process ends, the soft starter automatically uses the bypass contactor to replace the completed thyristor, providing the rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor and prolong the service life of the soft starter , To improve its efficiency, but also to avoid the harmonic pollution to the grid. Soft starter also provides soft stop function, soft stop and soft start the process of reverse, the voltage gradually reduced, the number of revolutions gradually reduced to zero, to avoid free-wheeling caused by the impact of torque. How the frequency converter works
- Q: Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
- Change 6 will only be slower, the fan is no longer role. The frequency converter has a power parameter, as long as the motor is less than or equal to this power can be.
- Q: The laptop's power adapter is broken how much it costs
- Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,
- Q: Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?
- The current amperage of the power adapter is only experienced at its maximum output power, as long as the power adapter output voltage and your original no problem. For example, when the home circuit from the power supply into the terminal does not limit the size of the current, but to provide a fixed voltage. The more your household appliances, the greater the current through the power supply into your home. And the indoor air break switch is a current limit, this is based on the ability to accept the wire. From the point of view of the meter, you use the power equal to UIt = W, where UI is the voltage and current, two multiplication is equal to power, power multiplied by time equal to power consumption. Say back to your power adapter, the power adapter output voltage is rated, as long as this notebook with your original output voltage is the same as your notebook will not hurt. And the power adapter current is the maximum output, the consciousness is the power adapter output maximum power P will not exceed this value, usually 65W or 90W. Greater than the power of such a computer can not be stable operation. Or a physical point of view, the use of notebook power adapter, in fact, the internal is a number of parallel circuits, secondary knowledge tells us the voltage of the parallel circuit at any end are the same size, and parallel devices, the greater the total current in the circuit The
- Q: B2b frequency how to speed
- How does changing the power frequency to change the speed of the motor? When the motor is connected to the power supply to drive the normal operation of the load, at this time to change the power frequency, such as the current frequency down, the motor armature rotating magnetic field speed will decline, the rotor conductor cutting magnetic field speed decreases, turn from the induced potential , The rotor current decreases, the torque decreases, the load on the shaft does not change, the torque will be less than the load resistance torque, the motor rotor speed decreases, the rotor conductor cutting the magnetic field line speed increases, the rotor induced potential increases, the rotor current increases, The torque rises until it is equal to the load resistance torque, and the speed is smaller than the original. After stabilizing the work, the torque of the motor is the same as that of the original. (The motor torque is the same as the load torque, the load is constant and the motor torque is not changed)
- Q: The laptop's power adapter can be used on a desktop computer
- Desktop machine is called DIY it ~ is the assembly machine inside the motherboard graphics card hard drive memory What is the need for power supply every power to have a different interface
- Q: 90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
- Two motors can use the same frequency converter, but the motor nameplate data through the parameters to adjust the input when the inverter should pay attention to some
