Overview
This device can automatically adjust the bus voltage and reactive power compensation, improve the voltage qualification rate and power factor.It is safe, reliable, convenient and flexible, fully utilizing the capacitor capacity, and improving operational efficiency. According to the total amount of reactive power that needs to be compensated, the connected capacitors can be automatically switched as a whole according to requirements and needs, or can be designed into several groups with equal or unequal capacities. The automatic switching device detects the voltage and reactive power of the power grid, and achieves the goal of automatic switching of capacitors through reasonable control and protection.
Implementation of standards
Firstly, let's take a look at the design specifications in GB 50227-2008. This specification is mainly applicable to parallel capacitor equipment in high-voltage AC power systems, aiming to ensure the safe and reliable operation of these equipment. The specification provides a detailed description of the technical requirements, parameter settings, design and manufacturing processes, installation and commissioning of the equipment to ensure compliance with relevant national standards and safety regulations.
Secondly, let's take a look at the technical standards for high-voltage parallel capacitor equipment in JB/T7111-1993. This standard is a technical specification for manufacturing and inspecting high-voltage parallel capacitor equipment, which specifies the technical parameters, structural design, manufacturing requirements, inspection methods, and other contents of the equipment. This standard emphasizes the quality and reliability of equipment, requiring manufacturers to strictly inspect and test the produced equipment to ensure its quality and reliability.
Finally, let's take a look at the technical conditions for high-voltage parallel capacitor equipment in DL/T 604-1996. This standard mainly specifies the technical conditions that should be met when ordering high-voltage parallel capacitor equipment, including the technical parameters, structural design, manufacturing, and quality requirements of the capacitor equipment. This standard requires that the purchaser should select equipment that meets the standard based on their own electricity needs and specific environmental requirements, and clearly require the manufacturer to comply with relevant standards for production and inspection in the order.
Model number and its meaning
Use environmental conditions
To ensure the normal operation of cable joints, it is necessary to comply with some usage conditions. Firstly, cable joints should be designed in a cabinet style when used indoors, and in a frame style when used outdoors. Secondly, the altitude should not exceed 1000 meters, and the ambient temperature should be between -25 ℃ and 40 ℃, with good heat dissipation. At the same time, there should be no serious pollution such as corrosive gases and water vapor in the surrounding air, and there should be no danger of combustible gases, fires, explosions, etc. In addition, places with frequent and severe vibrations should be avoided, and the voltage waveform distortion rate and harmonic content of the power grid should not exceed the standard regulations. Let's work together to maintain the normal operation of cable joints and ensure the stable operation of the power supply system.
