High-Voltage Motor No-Load Test System

I. System Composition

The system is applicable for1140V,3300V,6000V,10000VVoltage grade, motor capacity1000KWThe following comprehensive motor tests include parameters such as voltage, current, power, power factor, and frequency during the motor's no-load operation, as well as electrical strength, insulation resistance, direct resistance, and inter-turn impulse tests. These tests are conducted in real-time by industrial control computers, displaying the parameters of the tested products. The system primarily consists of a power cabinet, a three-phase oil-immersed electric voltage regulator, a high-voltage starting cabinet, a motor no-load test bench, and electrical wires and cables. The power cabinet, three-phase step-up transformer, and cables are to be provided by the buyer.

Two. System Workflow

The power cabinet is provided by the customer, with the output voltage of the power cabinet being low.380VThe content provided does not contain any Chinese text to translate.

The output signal of the high-voltage cabinet is connected to the motor test bench via voltage and current transformers inside the cabinet. Through the voltage, current, and power collection modules of the motor test bench, the collected data is communicated to the industrial control computer, achieving intelligent control, collection, statistics, and printing of the system.
