NR8300 series fully automatic motor comprehensive test system
The NR8300 series fully automatic motor comprehensive test system adopts advanced virtual instrument technology, which combines the powerful computing power of the computer with the hardware measurement and control capabilities of the instrument and equipment, and realizes the control of the test and the calculation, analysis and processing of the data through software. , Display, printing and storage, make the system function source more than the simple combination of ordinary instruments, especially in the results storage, waveform storage, synchronous measurement, test report generation, system expandability, multi-function and other aspects of the superiority of the traditional manual The test bench is incomparable.
The entire system is fully automated, fully microcomputerized, highly efficient, and designed with safety features to prevent misoperation. WINDODWS Chinese interface operation, automatic collection of measurement data, automatic calculation of results, automatic generation of factory test reports and print out, the measurement control system adopts PLC programming control, especially suitable for high product requirements and batch testing occasions.
Motor test is to use instruments, meters and related equipment, in accordance with relevant regulations, to conduct electrical performance, mechanical performance, safety performance and reliability of technical indicators such as semi-finished and finished products in the motor manufacturing process, or supporting products with motors as the main body. Inspection. Through these inspections, the relevant performance data of the tested motor can be reflected in whole or in part, and with these data, it can be judged whether the tested motor meets the design requirements, the quality of the quality, and the goal and direction of improvement. Motor test and inspection is an indispensable and important link in the process of motor research, production and maintenance. Therefore, for units engaged in motor research, production or maintenance, it is very necessary to have a set of motor testing and testing equipment that meets the requirements.
◆ The basic composition of the test system
The test system is composed of test power supply, power switch panel cabinet, signal sensing device and power measurement equipment, automatic test measurement unit and control console, AC motor test software system, database system and other parts. The load equipment in the type test can be selected according to user requirements to accompany test motors (including DC generators, AC generators, wound rotor motors), eddy current dynamometers, magnetic powder dynamometers, magnetic powder brakes and other equipment to meet Type testing of different motors is required.
◆ Measurement method: Microcomputer measurement
The measurement cabinet is equipped with current and voltage sensors, and the intermediate link adopts a signal conditioning interface module, and the computer completes the signal acquisition and measurement tasks;
◆ Control method: Directly controlled by automotive-grade MCU
Using Germany's Siemens automotive-grade micro-controller for interlocking control, the interlocking program can be customized and modified according to user requirements, the control system has stable performance and good system scalability;
◆ Operation mode: manual operation and automatic operation mode coexist
In order to avoid the influence of the test work when the computer fails, manual control (panel button operation) and automatic control (computer keyboard/mouse operation) coexist are adopted. It is inconvenient to use automatic control or the computer fails, and manual operation can be used for testing;
◆ Test data processing: test results are stored in the industrial computer or server
The microcomputer test bench is equipped with original industrial computers of well-known brands at home and abroad. The result data of automatic test is directly stored in the hard disk of the test industrial computer. The manually measured data can be manually input to the test software interface and then stored in the memory, providing the local database function. It can perform local query and access of test data, design with test report automatic generation function and provide output printing function (equipped with HP multifunction laser printer);
◆ High measurement accuracy and good repeatability;
◆ The control system has stable performance and good system scalability.
◆ Design principles: Reliability, safety, economy, practicability, operability, and maintainability are the design principles, while taking into account the advanced nature;
◆ Scope of application: meet the rated voltage of 380V, 660V, 1140V, 3300V, 6000V, 10000V; rated power of 1-15000kW, three-phase motor delivery and maintenance test (voltage level can be customized according to the actual requirements of customers);
◆ Test items: ambient temperature measurement, insulation resistance measurement, DC resistance measurement (calculation of three-phase resistance imbalance), power frequency withstand voltage test, turn-to-turn withstand voltage test, no-load test (calculation of three-phase current imbalance), Locked rotor test, loading test, efficiency test, temperature rise test (users can choose the above test items according to their own requirements);
◆ The system completes the measurement and calculation of voltage measurement, current measurement, power factor measurement, active power measurement, reactive power measurement, efficiency measurement, frequency measurement, output torque, output speed, output power, temperature rise, etc.
