\u2666How to choose a three-phase voltage stabilizer?<\/strong><\/h2>\n\n\n\n

Three-phase voltage stabilizers<\/strong><\/mark><\/a> are important instruments to ensure the normal work of industrial devices, commercial systems, and big household appliances. Especially in areas where there is a frequently fluctuated power grid, three-phase voltage regulators will regulate the input voltage effectively and then offer safe and stable power for equipment. How to select correctly, install correctly, safely use a three-phase voltage regulator? The following questions will be answered by ZHENGXI.<\/p>\n\n\n\n

1. Determine the power demand of the equipment<\/strong><\/strong><\/h3>\n\n\n\n

In selecting a three-phase voltage stabilizer, you have to understand the overall power requirement of all electrical equipment. It should be noted that the selection of the voltage stabilizer should be 20%-30% higher than the actual load to avoid the impact caused by the starting current.<\/p>\n\n\n\n

For purely resistive loads, such as incandescent lamps, resistance furnaces, the power of the voltage stabilizer must be 1.5 – 2 times that of the equipment.<\/p>\n\n\n\n

For inductive and capacitive loads like motors, water pumps, air conditioners, it is recommended that the power of voltage stabilizer is 3 times to cope with sudden increase in starting current.<\/p>\n\n\n\n

2. Input and output voltage range<\/strong><\/strong><\/h3>\n\n\n\n

When choosing a AVR voltage regulator<\/mark><\/a>, first of all, make sure the input voltage range is appropriate for local power grid fluctuations. For example, the voltage stabilizer that you can use in such areas where voltage fluctuations are huge is one whose input range can allow 304-456V so that it allows for stable power supply.<\/p>\n\n\n\n

3. Voltage stabilization accuracy and response speed<\/strong><\/strong><\/h3>\n\n\n\n

High-precision voltage regulators can be applied to equipment that requires high voltage stability, such as precision instruments and data centers. The voltage stabilization accuracy is \u00b12%-3%.<\/p>\n\n\n\n

If there is a requirement for response speed, you can choose servo motor-type voltage stabilizer, whose response speed is usually \u22641s.<\/p>\n\n\n\n

4. Choose the right type of voltage stabilizer<\/h3>\n\n\n\n

Servo control voltage stabilizer: apply to scenes that need quick adjustment of voltage.<\/p>\n\n\n\n

Static Voltage Stabilizer: The design is contact-free, maintenance-free, and suitable for applications that require long-time running continuously.<\/p>\n\n\n\n

\u2666 Safety issues of three-phase voltage stabilizer and how to connect them<\/strong><\/h2>\n\n\n\n

1. Grounding and protection<\/strong><\/strong><\/h3>\n\n\n\n

The voltage stabilizer should be reliably grounded in order to avoid leakage accidents. The grounding line should never be connected to the public facilities such as a water supply and gas pipelines.<\/p>\n\n\n\n

Lightning arrester: The voltage stabilizer should be installed in one surge protection device, avoiding bad damage by a stroke of lightning or instantaneous voltage fluctuation in the power network.<\/p>\n\n\n\n

2. Correct wiring<\/strong><\/strong><\/h3>\n\n\n\n

In this condition, the input and output wires should be in a state to carry sufficient current at the time of installation to avoid hazards of safety due to heating of the wires.<\/p>\n\n\n\n

Loose or not equipment terminals should be checked from time to time to avoid any sort of short circuit or fire.<\/p>\n\n\n\n

3. Precautions for equipment operation<\/strong><\/strong><\/h3>\n\n\n\n

Shall not dismantle the voltage stabilizer without permission or change at will. The maintenance should not be done by any non-professional to avoid accidents of electric shock.<\/p>\n\n\n\n

The voltage stabilizer should be installed in such a manner to avoid strong vibration during operation; otherwise, this may damage its internal parts.<\/p>\n\n\n\n
