I believe everyone does not know much about the stabilizer, but it plays a great role in our home.It can automatically adjust the power supply equipment of the output voltage, so that the fluctuating unstable unstable power supply voltage stabilizes within the corresponding range, so that various circuits electrical equipment, etc.So how to use the stabilizer?How can we buy it?
Stabilizer power
1. The power labeled by the regulator is the maximum power.The nominal power of household appliances refers to the power, while the emotional loads such as refrigerators, air conditioners, and pumps are very current at the moment of start. Therefore, the refrigerator, air conditioning, and water pump are based on power × (3 to 5 times).
For example: 3 Hemo air conditioners (220V power)
1 horsepower is equal to 0.75 kW × 3 pyramid = 2.25 kW × 3 times the emotional load start current = 6.75 kilowatt stabilizer.(Midea repair and installed technicians recommend using 8KVA regulator)
2. Power algorithm for professional electricity, engineers, and voltage regulators with professional hydropower installation technicians and factories: General industrial equipment uses the rated power at least 2 times to use power.When sexual load equipment, a voltage regulator with a capacity of more than 3 times should be selected to avoid the launch of the current and the pressure supply line to reduce the pressure and cannot work properly.
For example: a motor power of a steam pump (380V electric equipment) of a factory is 7.5 kilowatts. However, when it starts to run the impact, the wave current has more than 3 times the power of the motor.Stabilizer.
3. When the 0.5KVA -3KVA regulator selects the output voltage 110V, the input capacity cannot exceed 40%of the rated capacity. When the output is used at 110V and 220V, the output capacity shall be 50%of the rated capacity to avoid overload.
Stabilizer purchase
When buying a stabilizer, it is recommended that you buy at least three times the voltage regulator that is three times larger than the actual power, because the stabilizer must overcome the impact of the municipal electricity shock and the starting impact of the emotional load (such as the refrigerator, air conditioning, Motor and motor).
1、稳压器用在感性负载时，由于感性负载有较大的瞬间起动电流，一般约为额定电流的3—5倍往往超过运行电流的9倍(如电冰箱、空调器、洗衣机、电扇、Large air conditioners, printing machines, air compressors, elevators, pumps, etc. are all perceptual loads), so the voltage regulators that are equipped with emotional loads such as motor and compressed electrical appliances must consider their power reserves and leave a waste.It is necessary to reserve enough margin to avoid instant damage caused by the stabilizer when the stretch is turned on.If the entire plant uses a regulator, when starting the machine, it should be avoided at the same time at the same time, so when purchasing the regulator, there should be 1.5 times the reserved capacity of the capacity of the single machine.Essence
2. Pay attention to the voltage value of the electricity supply, whether it exceeds the input voltage range specified by the purchased voltage regulator, whether the three -phase electric voltage is more than 10V or more
3. Before the purchase machine, consider the future business expansion, whether the equipment needs to be increased, and whether the regulator needs to reserve the extension capacity
4. Whether it is a stand -alone matching or the entire factory support, the purchased voltage device must reserve a certain reserved capacity to avoid 100%load rate of the regulator. The load rate of the regulator is generally 90%.EssenceThe shape structure of the automatic pressure regulator includes several types of tablet, wall -hanging, dual -use and floor -to -ceiling type. You should choose different styles according to the location, main purpose, and installation capacity of the installation.
5. Industry insiders remind that when choosing a regulator, pay attention to choose products with high brand awareness, because these manufacturers have a reliable quality and thoughtful service; at the same time, whether the manufacturers have good after -sales service, such as three packages of product quality execution, etc.It is also an important factor that consumers should pay attention to.
How to use the stabilizer
1. Access to the municipal electricity (in accordance with the national regulations of the left and right fire wiring standards)
① The input wire diameter of the access device must ensure ≥25mm2 copper core wire
② Input of the access device, the output cable card is tightened
③ The input and output cable must not be connected
④ The front end of the device cannot replace the air switch with a leakage protector
2. The maximum power of the connection load load cannot exceed the voltage voltage power supply: Example: 50kva. The general load rate is 50kva × 0.8 = 40kW ① All line interfaces of the output line must be tightened, otherwise the line will be fever due to the large current,To affect effective power.
3. Turn on the voltage voltage power supply (strictly prohibited to turn on the load first, and then turn on the voltage voltage power supply)
① Please ensure that the computer display is turned on and the voltage supply is turned on.
② The measured voltage value should be between 304V-456V before turning on.
③ The output voltage table that comes with the machine should be 380V.
4. Do not use too high loads;
5. Please use enough wires;
6. Please be careful to connect the output of the input voltage and the instrument and equipment;
7. The output voltage of the instrument equipment and the regulator should be unified;
8. Please select the input voltage switch as the power supply voltage;
9. If the fuse is burned out, please check the load equipment;
10. Use a certain fuse with a certain amount of fuses. Non -rated fuses or wires cannot be used;
11. Installed in a dry and ventilated place.
