It can be conveniently and accurately used to calibrate various models of single-phase or three-phase DC resistance testers currently produced in the market.
The various analog and digital grounding resistance meters and imported similar instruments of the KDJD-1D grounding resistance meter calibration device can also be used as DC resistance boxes.
The KDZR-20L DC motor inter chip resistance tester can effectively detect whether the welding between the commutator and the winding is good, and whether there are any adverse phenomena such as open circuits or short circuits in the winding.
The KDZR-40L DC motor inter chip resistance tester can effectively detect whether the welding between the commutator and the winding is good, and whether there are any adverse phenomena such as open circuits or short circuits in the winding.
The KDZD-630/1140 explosion-proof electrical protection performance test bench is suitable for QBZ, BKZ, BKD, BGP and other series switches
The KDZD-S18 pump comprehensive performance testing system has the advantages of fast testing speed, high accuracy, convenient use, and good reliability.
The KDXZ-970 generator power frequency withstand voltage test device adopts a working mode of parallel connection of multiple reactors, adjusts the inductance of adjustable reactors, and achieves resonance state by connecting fixed reactors of different numbers in parallel. Reasonably configure fixed and adjustable reactors of different capacities according to the size of the test capacity, in order to reduce the power supply capacity and the volume and weight of the test equipment.
