      Outdoor Ring Net Box QHB

      Outdoor Ring Net Box QHB

      Product introduction With the continuous development and progress of the society, China's urban power grid has undergone tremendous changes, and most cities have formed or are forming numerous power-intensive areas. In the past, the power supply method from the substation 10kV line (or branch line) to the direct user has been difficult to meet the requirements of urban development. Therefore, a new power supply mode is generated, which supplies power to the user through opening and closing. However, as the degree of urban intensification has intensified, some of the original civil-type opening and closing houses have been restricted by land and urban planning. Therefore, a more advanced and practical power distribution equipment has emerged as an outdoor small intelligent opening and closing station. Outdoor ring network cabinet). This opening and closing station does not require civil works and has a small footprint and a very flexible configuration. The power supply method is more reliable. The construction, installation and commissioning time is greatly shortened, and the overall cost is reduced. With the development of modern industry, the automation and intelligence of electrical equipment control is getting higher and higher, using modern electronic technology, sensor technology, communication technology, computer and network technology to monitor and protect power equipment under normal and accident conditions. Integration, control, measurement, etc., to achieve good management, has become an inevitable trend and development direction. The intelligent small opening and closing station (outdoor ring network cabinet) adopts the European opening and closing scheme, 10kV switchgear, circuit breaker, load switch, current CT, voltage transformer PT, FTU, RTU, communication control terminal ) CCU, 10kV metering and automatic meter reading, UPS power supply and indicating instruments are installed and debugged into a removable, sealed and moisture-proof stainless steel box. Thereby, the integration of the primary and secondary systems in the urban distribution network and the modularization of the assembly are realized. Shortened the construction period. Greatly improve the reliability of urban power grid operation. Model and meaning Technical Parameters Conditions of Use a. Use place: outdoor b, adapt to the ambient temperature: -35 ° C - +55 ° C c, the highest daily average temperature +40 ° C, the highest annual average temperature +35 ° C d, wind speed: no more than 35 m / sec e, relative humidity of the air: "90% (+25 ° C) f, ground inclination "5 ° g. Earthquake tolerance: the seismic intensity does not exceed 8 degrees h, no fire, explosion hazard, chemical corrosion and severe vibration at the installation site ?
      Series (filter) reactor

      Series (filter) reactor

      Pure dry structure, resin casting, with secondary protection temperature control switch. It adopts high-quality silicon steel sheet, high insulation grade winding, low temperature rise, low loss, low noise and strong overload capability. The vacuum pressure impregnation technology is adopted to make the winding and the iron core firmly and perfectly combined, the corrosion resistance is strong, and the electrical performance is more stable. ? Application Capacitors in the reactive power compensation loop are often affected by harmonic currents, switching inrush currents and overvoltages, causing capacitors to be easily damaged. Therefore, a certain proportion of reactors are connected in series to suppress and absorb some harmonics, which can significantly improve the power supply system. Reliability and stability, in many cases, such as when the harmonic content of the power grid is large, the reactors matched with the capacitors must be connected in series. ? The role of two reactors 1. Suppress harmonic amplification and filter out a certain proportion of harmonics 2. After precise matching, a passive filter is formed in series with the capacitor to accurately filter out a certain harmonic. 3. Suppress the inrush current when the capacitor is put in, and protect the capacitor and other devices.

      original imported The filtering effect is good, the main components are imported, the design margin is sufficient, the overload capability is strong, stable and reliable, and the service life is long. ? Automatically suppress overload The device is independent of the grid impedance and system impedance, independent of grid impedance and system impedance changes, automatically suppresses overload and has no resonance risk. ? Soft start The soft start scheme is adopted to eliminate the disturbance to the power grid at the moment of the retreat, realize the impact-free start of the power grid, automatically detect and track the harmonic changes of the power grid, and do not need to be manually guarded. ? Fully modular design Fully modular design, self-diagnosis and self-recovery function, complete protection function and operation status record, installation, debugging, maintenance, retreat and other operations do not affect the user's normal power supply. ? No grid radiation The radiation to the grid complies with the requirements of the electromagnetic compatibility standard. ? Product description H-Bright-APF series low-voltage edge filter is the latest generation of all-digital harmonic elimination equipment independently developed by our company. It has special advantages compared with traditional technology, faster, smaller, more powerful, easy to install and easy to debug. Convenience, these advantages make it easy to solve power quality problems. In addition to dynamically compensating for harmonics, the product can also perform reactive power compensation and solve power quality problems such as voltage fluctuations and flicker. At the same time, this series of products adopts the most advanced control technology to achieve full automation control, which is the first choice for eliminating harmonics. ? Second working principle APF uses power electronics technology. The main components of the device include: controller, converter, DC support capacitor, and connected reactor. The APF control system includes DSP+FPGA, command current calculation circuit and current tracking control circuit to realize functions such as parameter setting and control command acquisition. ? The APF detects the load current through the current transformer and extracts the harmonic components in the load current through the internal DSP calculation, and then sends the PWM signal to the internal IGBT to control the inverter to generate a harmonious load. The harmonic currents are equal in magnitude and opposite in direction. The harmonic current is injected into the grid for filtering purposes.
