From the design concept, mnsis is an overall solution for the intelligent motor control center, which not only considers the intelligent components of motor protection, but also comprehensively considers the needs of communication and network structure, and makes innovations in the cabinet structure and detection technology. Mnsis enables the motor control center to achieve unprecedented standardization and modularization. And the primary and secondary parts are completely separated in structure, making the product easier to use, maintain and even upgrade. It uses common third-party hardware and software to increase the openness and versatility of the product.

The primary part of mnsis is of drawer type design, called mstarter. Only primary components of motor circuit such as main switch and contactor are installed in the drawer. As we all know, the coordination of the primary components of the motor protection circuit does not change much, but the requirements of the control part are ever-changing. If the control part is separated from the main circuit, it is possible to standardize the main circuit.

In mnsis, the type selection and matching of primary components of various types of motor starter circuits are selected according to the requirements of iec60947-4-1 motor protection and matching type2, and are fixed. The drawer size required for this primary circuit can also be determined. All motor starter circuits with different rated power can be divided into standard 30 to 40 types of drawers. Considering different starting modes (such as dol, rev, SD), short-circuit capacity (50kA, 80kA, etc.) and the type of main switch (such as circuit breaker or fuse), a limited number of drawer types can be determined for standardized production. The designer no longer needs to select the main switch and contactor. After knowing the parameters of the motor circuit, the unique mstarter is determined. For example:

3KW motor starter, 400V, 50kA, main switch adopts MCCB, direct start

Based on this information, an mstarter can be uniquely determined with a size of 6e / 4. According to the order number, the customer can directly purchase the functional tested, complete primary drawer from the manufacturer. Its internal component coordination, structure and assembly have been fully considered and optimized.

1.2 intelligent sensor

Inside mstarter, mnsis adopts a new intelligent sensing technology for the low-voltage switchgear industry. It is an intelligent sensing technology based on shunt resistance, which is adopted from the automotive industry. It completes the detection function through a chip embedded in a conductor. The intelligent sensor is installed at the outlet end of mstarter, and can simultaneously measure the voltage, current and temperature on the conductor at the outlet end. The output of the sensor is a digital signal, which is connected to the terminal through the data line and led out to the slot of the mnsis control module through the control adapter. The intelligent sensor replaces the traditional current transformer and brings the advantages that the current transformer does not have. First, the volume is reduced and the installation space is saved. Secondly, the accuracy is improved. The traditional CT works according to the principle of electromagnetic induction. Because of the characteristic of magnetic saturation, its measurement value is nonlinear and can only guarantee the accuracy of an intermediate measurement range. The measured values of the intelligent sensor in its full measuring range are digitized, and the accuracy is well guaranteed. Thirdly, the power loss caused by the sensor coil is reduced, and the heating capacity of the cabinet is reduced.
