Static VAR generator (SVG) is a representative of the latest technology in the field of VAR compensation. SVG in parallel in the power grid, equivalent to a variable reactive current source, the reactive current can be flexibly controlled, automatic compensation system required reactive power. Because of its extremely fast response speed, it is also called Static Synchronous Compensator (Static Synchronous Compensator).
An-ca series dry self-healing low voltage parallel capacitor is AN upgrade product of BCMJ/BSMJ capacitor. This product introduces advanced capacitor manufacturing technology from Europe and advanced capacitor manufacturing equipment. It adopts uniquely designed self-healing metallized film, which greatly enhances the end joint force of capacitor components. Thus, the inrush current resistance and reliability of the capacitor are enhanced.
AN-TSC/T series dynamic switching switches are designed for dynamic and fast compensation of 0.22~0.69KV power capacitors. It is mainly applicable to the electric load site that requires quick switching capacitors for impact loads, such as welding machines, steel rolling, port cranes, elevators, variable frequency furnaces and other rapidly changing loads.
The iron core is made of high-quality low-loss cold rolled oriented silicon steel sheet. The pillar of the core is split into small, even sections by numerous air vents. The gaps use an epoxy layer of glass cloth panels to form intervals, ensuring that the reactance of the gaps does not change during operation. The solenoids use a tightly packed and uniform Class H flat copper wiring system. It boasts an exceptional fine appearance and an excellent ability to dissipate heat. The solenoids and iron core are assembled into one and go through the process of pre-baking vacuum impregnation, heat curing, and solidification.
AN-RVT/K series reactive power compensation controller, is widely used in reactive power compensation control system Mainly by power module, data acquisition, man-machine interface, reactive power compensation control and GPRS data module five parts, GPRS network communication technology is mature, wide coverage, It is an important direction of power system modernization to realize data collection and monitoring of distribution network by using wireless network provided by mobile operators.
Flexible control mode, active and passive technology complementary advantages. Automatically track the load change, can be separated phase endless output capacitive or inductive reactive current, dynamic continuous adjustment, to achieve stepless compensation. TSC switching capacitor adopts zero crossing switching technology, no inrush current when put in
In addition to filtering, the APF branch can also enable the reactive power compensation function and output reactive power in both directions. The output reactive power can be continuously adjusted within the capacity range of the whole machine; Power factor can reach more than 0.99 (if the total compensation capacity is sufficient);
Vertical and horizontal busbars are connected in cross-over mode. Instead of the traditional wiring harness connection, completely solve the wiring harness winding problem, the cabinet is simple and clear. TSC series thyristor switching switch is selected. The thyristor switching switch has zero dynamic switching, fast response speed (1 ~ 20ms), no mechanical wear, no noise and long service life.
Modular design, any module failure will not affect the normal work of other modules, greatly improve the reliability of the whole equipment; It can realize smooth expansion of multiple units running directly in parallel. When multiple devices are added, the master/slave control mode is adopted. When multiple modules are connected in parallel, all modules can share a set of current transformer; It can filter the odd harmonic current below 2~50 times at the same time, and can set the harmonic subsegment that needs 13 kinds of filtering according to the need. When the load current distortion rate is greater than 20%, the filtration rate is not less than 85%; When the load current distortion rate is less than 20%, the filtration rate is not less than 75%
