How to choose a 3 Phase Stabilizer?

P1:How to choose a 3 Phase Stabilizer?


First of all, it depends on the type of your electrical equipment. Generally, the load is not purely resistive. Therefore, in practice selection, the stabilized power supply should be selected reasonably according to the details of the additional power, power factor and load type of the electrical equipment, and its output power should be left with appropriate margin, especially the margin for impact load selection. To be bigger, how to choose the 3 phase stabilizer is as follows:

 

⒈For pure resistive loads such as incandescent lamps, resistance wires, electric furnaces and other equipment, the power of the three-phase regulator should be 1.5 to 2 times the power of the load equipment.


⒉Rational and capacitive loads such as fluorescent lamps, fans, motors, water pumps, air conditioners, computers, refrigerators, etc. The power of the three-phase regulator should be 3 times the power of the load equipment.


⒊Under the environment of large electrical rationality and capacitive load, the starting current of the load should be considered when selecting the model is particularly large (up to 5-8 times the extra current), so the power of the three-phase regulator should be more than 3 times the load power .


P2:3 Phase Stabilizer safety issues


⒈When the stabilized power supply is powered on, please do not disassemble the stabilized power supply or pull the input and output connection of the stabilized power supply at will to prevent electric shock or other electrical safety accidents.


⒉The input and output connections of the stabilized power supply must be arranged reasonably to avoid being trampled and worn out and causing leakage accidents.


⒊The stabilized power supply must be grounded reliably, and the user shall be responsible for the electric shock or human body damage caused by the operation without the grounding wire.


⒋The ground wire of the stabilized power supply cannot be connected to public welfare facilities such as heating pipelines, water supply pipelines, gas pipelines, etc., to avoid infringement of third-party power or causing harm.


⒌Check the input and output connections of the stabilized power supply regularly to avoid loosening or falling, which will affect the normal operation and safety of the three-phase stabilized power supply.


⒍The selection of the connecting wire of the three-phase voltage stabilizer must reach the connecting wire that can carry the current capacity specified.


⒎The three-phase voltage stabilizer should be handled with care to avoid violent oscillation during work;


⒏Ensure that the carbon brush spring of the three-phase voltage stabilizer has sufficient pressure to avoid flashover on the contact surface of the carbon brush and the coil;


9. Non-professionals, please do not disassemble or repair the stabilized power supply.


P3:3 Phase Stabilizer installation and application


⒈Connect the three-phase voltage stabilizer input to the power distribution board, and install a fuse that meets the power guarantee rate of this instrument on the user power distribution board to ensure the safety of electricity.


⒉Connect the power supply of the electrical equipment to the output terminal of the instrument, pay attention to the additional input voltage value of the electrical appliance should be the same as the output of the three-phase transformer and the three-phase voltage stabilizer.


⒊Open the power switch of the three-phase voltage stabilizer first, and the operation indicator light is on. Check whether the indicated value of the voltmeter is normal. When the output voltage is normal, turn on the power switch of the electrical equipment again, and the three-phase voltage stabilizer can automatically adjust the voltage and supply the three-phase voltage stabilizer manufacturer normally.


⒋When the electrical equipment is not used for a long time, please close the power switch of the electrical equipment to reduce power consumption and extend the service life of the three-phase voltage stabilizer.


⒌Three-phase voltage stabilizer shall not be used in overload. When the mains voltage is low, the output capacity is reduced, and the load of the three-phase regulator should be reduced accordingly.


⒍When selecting electrical appliances such as refrigerators, air conditioners, water pumps and other electrical equipment, 3 phase stabilizer with a capacity of more than 3 times should be selected to prevent the starting current of the equipment from exceeding the three-phase voltage stabilizer fuse current or the overcurrent protection circuit breaker current The fuse of the three-phase voltage stabilizer is blown or the circuit breaker is tripped or the voltage drop is too large to work.


⒎The wire connected to the 3 phase stabilizer should have a sufficient load surface to avoid heat generation and reduce voltage drop. For three-phase voltage stabilizers with a capacity of 2KVA or more, terminal connections should be used. A single copper wire should be used, and the terminal screws should be tightened as much as possible to avoid heat generation at the connection.


⒏Whether it is a single-phase or 3 phase stabilizer, after connecting all input and output lines, turn off the power switch of the load first, and then open the three-phase voltage stabilizer, and then open the load switch.
