Advantages of High Voltage Capacitor Compensation Cabinet in Power Supply and Distribution System in Xiangyang City, Hubei Province
Capacitor compensation cabinet occupies a very important position in the power supply system. Both high-voltage capacitor compensation cabinet and low-voltage capacitor compensation cabinet are widely used in people's lives. Especially in recent years, the sales market of capacitor compensation cabinet in Xiangyang City, Hubei Province ushered in spring and was closely concerned by customers. What are the advantages of high-voltage and low-voltage capacitor compensation cabinets in the power supply system? Wuhan Yuanchuang Electrical Equipment Li Gong takes high-voltage capacitor compensation cabinets as an example to show you the efficacy and performance advantages of high-voltage and low-voltage capacitor compensation cabinets.
the efficacy of high voltage capacitor compensation cabinet:
It is used in 6KV-10KV power supply system to improve power factor, adjust working voltage and reduce consumption. It is also widely used in high-voltage motor equipment with high power in metallurgical industry, mining, decorative building materials, petrochemical industry, water supply and drainage, etc. It runs in parallel with motors to improve power factor and save energy.
Performance characteristics of high voltage capacitor compensation cabinet:
The use of well-known components, the use of advanced design, long service life of equipment.
Reasonable configuration, humanized design, practical operation, application and maintenance are convenient.
Built-in charging and discharging equipment to ensure personal safety and equipment.
With triangle and over-current, over-voltage protection and other protection functions, so that reliable operation.
The use of electroplating spray coating film plating polypropylene film parallel capacitor, itself consumption is small, because the polypropylene film has a high magnetic field strength and low dielectric loss and small size, easy to carry, small consumption, light weight and other advantages.
Evaluation of capacitors The error of the capacitor and the rated current does not exceed the rated current.
The series reactor can be modified to limit the surge voltage of the capacitor composition gate process, limit the impact of operating overvoltage and suppression of high-order harmonics in the power grid on the capacitor.
The power saving effect is remarkable, the power factor of the power grid is raised above 0.95, the current flow is reduced by 10% ~ 20%, and the line loss rate is effectively reduced.
Its own consumption is low, the capacitor used in this equipment, its own energy loss is very small is the following of the general oil to low bladder capacitor.
Considering the specific situation of the customer, the capacitor bank of the nearest compensation cabinet and the relevant control system are placed in the same box, which is conducive to the installation and application of the stand-alone version of the high-voltage motor at the nearest compensation site.
The use scenario of the high-voltage capacitor compensation cabinet shall meet the following requirements:
Indoor application, good ventilation.
Indoor assembly, the average altitude is not more than 1000m, no strong vibration analysis, no harmful substances and dust, no conductivity and floating dust.
Long-term overvoltage (no more than 4 hours in 24h) shall not exceed 1.1Un, and long-term overvoltage (including harmonic current) shall not exceed 1.35Un.
Natural ambient temperature: ambient gas temperature does not exceed 40 ℃, and the lower limit of gas temperature when the capacitor is put into operation is -40 ℃.
Air standard: air humidity at +40 ℃ does not exceed 50%, at relatively low temperatures allow high air humidity, and should be noted because of temperature changes and may produce condensation phenomenon.
The assembly slope shall not exceed 5 °.
