First, the CDP6 motor circuit breaker can give the motor full control and protection. By integrating the functions of short-circuit protection, phase-failure protection and thermal overload protection, the previous generation of molded case circuit breakers and miniature circuit-breakers have been successfully avoided.
Secondly, the CDP6 motor circuit breaker adopts a modular positive-fit auxiliary contact protection cover. The humanized buttons and the integrated logo design all make the overall shape and structure calm and atmospheric.
In addition, the installation of the circuit breaker is also different from the past. Unarmed hands can complete the loading and unloading without the aid of any tools. At the same time, the CDP6 has an extremely large torque of 1.7 Nm in the main loop, making the wiring more robust.
On-Grid Inverter converts DC power to AC power for feeding back to the grid. The frequency of the output voltage of the grid-connected inverter needs to be the same as the grid frequency (50 or 60Hz), which is generally achieved by the oscillator in the machine, and the output voltage will also be limited not to exceed the grid voltage. Modern high-quality grid-connected inverters can have an output power factor of 1, which means that the output voltage and current phases are the same, and the phase difference between them and the grid voltage is within 1 degree. There is a microprocessor in the inverter that can sense the AC waveform of the grid, and according to this waveform, generate voltage and send it back to the grid. However, the electricity sent back to the grid needs to have a certain proportion of reactive power, so that the power of the nearby grid is within the allowable limit. noon) its voltage may rise too high.
If the power of the grid is cut off, the grid-connected inverter needs to be disconnected from the grid quickly. This is a regulation of the National Electrical Code (NEC) in the United States to ensure that when the grid is out of power, the grid-connected inverter will not provide power to the grid, and at this time the workers who maintain the grid will not be electrocuted.
Properly configured, grid-tie inverters allow a home to use alternative energy sources that it generates itself (such as solar or wind power) without cumbersome wiring and without the need for batteries. If there is insufficient alternative energy, the insufficient part will still be provided by electricity from the grid.
Grid-connected inverters are widely used in household photovoltaic power generation systems, commercial and industrial photovoltaic power plants and other scenarios. By connecting to the grid, they help to achieve efficient use of renewable energy and reduce carbon emissions, promoting sustainable development and popularization of clean energy.
