An enterprise integrating intelligent manufacturing and technology research and development of high and low voltage transmission and distribution equipment, power quality, electrical automation, technical consulting, scientific research, production, sales and operation management
Impedance Characteristic Monitoring Device
The KSZKTXJK-6800 impedance‑characteristic protection device is suitable for the protection of shunt capacitor banks, online power‑quality monitoring, and early‑warning protection of capacitors, reactors, and discharge coils in non‑directly grounded or low‑resistance‑grounded systems at 110 kV and below. This online monitoring unit can effectively assess the operating condition of shunt capacitor banks; when capacitor or reactor parameters deviate or a fault occurs, it provides timely warnings and trip‑out protection, while also enabling fault analysis and location.
Microcomputer Protection Measurement And Control Device
The KSTC900W series protection and control devices comprise generator protection, main transformer protection, line protection, transformer protection, capacitor protection, motor protection, reactor protection, automatic transfer switch (ATS) protection, PT protection, and more. They are suitable for power grids at 110 kV and below, as well as for plant auxiliary power systems in power plants. By integrating protection, measurement, control, and communication functions into a single unit through the use of a high‑performance 32‑bit CPU, these devices are ideally suited for deployment with substation integrated automation systems or plant electrical automation systems. The units can be mounted on panel boards for centralized installation, or directly installed on switchgear for distributed control.
AC Dynamic Voltage Restorer (KS-DVR)
The KS-DVR employs power electronics technology; when the system voltage experiences a sudden dip, the device can rapidly regulate the voltage, while also mitigating three-phase voltage imbalance and correcting voltage deviations. This ensures seamless transition of the output voltage to its rated value, thereby guaranteeing normal and stable operation of the load.
The KS825 series of electrical measuring instruments encompasses: the 2000 series comprehensive power quality analyzers; the Y LCD series multifunctional power measurement and control meters and smart meters; the W LED‑display series multifunctional power meters and smart meters; and the N LED‑display series electrical measuring instruments, meeting a wide range of user requirements. Featuring a highly integrated product lineup, full functionality, advanced system‑level metering chip technology, superior anti‑interference performance, and enhanced real‑time true RMS measurement, these products deliver reliable quality—making them a trustworthy choice.
Complete Set Of Flexible Instantaneous Arc Suppression Coil
The operating principle of a bias‑magnetized arc‑suppression coil is to use an auxiliary DC excitation to magnetize the iron core, thereby varying the core’s permeability and achieving continuous adjustment of inductance. The DC‑biased arc‑suppression coil is an arc‑suppression device whose inductance can be continuously tuned; it features an all‑static internal structure with no moving parts, ensuring high operational reliability. It also boasts a rapid response time and can adjust its inductance even when subjected to high voltages.
The intelligent control device features a primary circuit simulation diagram and switch‑state indicators, high‑voltage live‑display functionality, automatic temperature and humidity control, human‑presence‑activated automatic lighting, voice prompts, electrical parameter measurement, and an RS‑485 communication interface, integrating operation and display in a single unit.
