Applications:

Introduction to Application Environment of KDSL-S500A Three-phase Large Current Generator (simplified version)

KDSL-S500A three-phase large current generator is applicable to the site and laboratory environment of power system, industrial and mining enterprises, electrical equipment manufacturing and testing units, and is mainly used for power-on verification and overload/short circuit characteristic test of thermal relay, motor protector, circuit breaker, contactor, switch cabinet, protection panel and other equipment.

The equipment conforms to GB6587.1-86 Group III instrument standard, can operate stably in indoor or outdoor conventional environment, and adapt to substation, distribution room, maintenance workshop, commissioning site and other working conditions. It is small in size, light in weight, strong in anti-jamming capability, supports AC 380V/220V three-phase four-wire power supply, outputs 0~500A continuously adjustable standard sine wave large current, meets the test requirements of high accuracy (0.5 level) and high stability (current stability of 0.5%), and is an ideal tool for verification and function verification of electrical protection devices.

Profile:

KDSL-S500A three-phase large current generator is a high-precision and portable test device specially designed for verification of electrical protection equipment. Numerical control technology and low-power large-capacity auto-coupled voltage regulator are adopted, with output current of 0-500A continuously adjustable, pure waveform (ripple coefficient<0.3%) and accuracy of 0.5 level, fully meeting strict requirements of power system for relay protection device test. The equipment is compact in structure and light in weight, only 30% - 70% of that of similar products. It is equipped with digital display ampere meter, which is intuitive and convenient to operate, and has double protection against overcurrent and overvoltage. It is applicable to substation, power supply station, switch plant, inspection center and other places, widely used for ex-factory test, handover acceptance and regular calibration of circuit breaker, thermal relay, motor protector, distribution cabinet and other equipment. It is an efficient and reliable tool for power operation, maintenance and quality inspection.
