Safeguarding the New Energy System | GRL DNH1 Series Switch Unlocking New Skills
What can we do for new energy?
According to industry data in 2021, the cumulative installed capacity of new energy has reached 30%, and the power generation has also reached 12% of the annual total power generation. Driven by the “dual carbon” strategy, the future new energy market will still achieve better development.
At the technical level, in order to improve energy efficiency, whether it is photovoltaic, wind power, or energy storage systems, the system voltage is constantly increasing. Conventional short circuit protection products such as 400V/690V fuses and fuse switches are no longer able to meet the needs of the new energy field.
At the same time, there are certain differences in the voltage of each link in the new energy system, which poses a challenge for electrical protection manufacturers.DNH1 Series Switch
The high efficiency brought by high voltage can greatly improve work efficiency, but it also brings high risks. Once the circuit malfunctions, the overloaded energy will bring tremendous destructive power.
At this point, fuses and circuit breakers play a crucial role. Common short-circuit protection devices include circuit breakers and fuses. Although they are all circuit protection devices, there are still some differences in their working principles and protection categories.
Among them, the fuse and its combination device, as a key protective device, quickly fuse under the action of short-circuit current, thereby playing an instant role in protecting the circuit and equipment. This protection method of fuses has the advantages of smaller size, high breaking capacity, high reliability, and low cost in short circuit protection.
The GRL DNH1 series fuse type isolation switch has been newly upgraded, providing reliable power protection for all aspects of the new energy system.
