First,Outlined
Type Tbbz Automatic Switch Capacitor Compensive Installation is a new reactive power compensation equipment. Users can load voltage and reactive power and power factor changes and timely automatic vote or capacitors group, the grid voltage and power stability of a few requirements to the extent that realization of the best reactive load compensation, thereby improving the quality of grid voltage, and give full play to the provision of equipment efficiency and lower energy consumption. 1. Reactive power control systems, high-precision control group switching high voltage capacitors, voltage and reactive power compensation in the best condition. 2. Reactive Compensation high precision reactive power compensation controller provides an effective means of automatic control for reactive power compensation adjustments, switching control of a multi-level multi-cycle Fine compensation capacitor. Change the whole team in the past one-off series capacitors, and improve the accuracy of the compensation, premium and lump sum owed to completely resolve the issue of compensation could range : 0.92-0.98. 3. Reactive power control devices for industrial control computers at the core, integrated, real-time tracking and control of high voltage capacitors shipped from the switch-off. Devices with low power consumption, high reliability and long life characteristics. Flexible function expansion, product upgrades and maintenance easy. LCD interface using reality, while all of the information displayed on the screen, users can easily understand the device operation status. Also has a remote control device and communications adapter, it can conduct remote control monitoring. Device is simple, timely online revision features a variety of parameters. User parameters can be adjusted according to actual demand, the system will achieve the best operating results. 4. Switched capacitor circulation achieving control of high voltage capacitors multi-cycle switching positions, the capacitors "first vote cut" and "after vote after all" in a manner which avoids the capacitors themselves often running behind and the capacitors are often empty state. Switched capacitor cycle and the group voted to make the switch to use all probability equal, a balanced-off switching action, extending the life of the device. 5. Automatic and manual separation of layout of the control device used in the separation of control and manual control layout, since the need to overhaul some of the BO control switch for manual control can continue to work to achieve some of the control line maintenance equipment to ensure continuity of operation.
Second, performance
Device allows 1.1 times the rated voltage and frequency in long-term operation. Since the device allows voltage and high-order harmonic generation in the RMS current of 1.3 times the rated current stable than under continuous operation. Rated capacitor with capacitance devices practical difference does not exceed the rated 0~+10% installed between any two terminals to the maximum and minimum capacitance ratio is not more than 1.06. Capacitors installed and put into operation an instant can limit the inrush current capacitor 20 times the amount the group rated current.
Third, the implementation of standards JB7111-1993 high capacitance device GB50227-95 parallel shunt capacitor design standards GB/T11024.1-2001 nominal voltage power system using shunt capacitors MPC more exchanges and related standards Part.
Four, Structure Shunt capacitor device for the main, according to the user's needs, unmanned power compensation controller, discharge coils (voltage transformer), current transformer, vacuum contactors (VCB), Fuse, MOA, series reactor, isolation and protection switching and measurement, instructions, etc., enclosure using quality cold-rolled steel from the elbow. |
