The outdoor hydrophobic epoxy resin is used as an insulating material, with a life of more than 40 years, vacuum arc, solid insulation, oilless, no sf6No environmental pollution, no explosion and gas leaks, meet environmental requirements. |
Fully sealed waterproof design, high voltage conductor is not exposed, especially for humid and flooded regions, can be reliably powered in wet and water. |
The operating mechanism can select a permanent magnet operating mechanism or a spring operating mechanism according to user habits and actual needs. |
Isolation, ground switch and circuit breaker integrated design, compact structure and have a sound mechanical and electrical interlock design, which can effectively prevent errors. |
A rapid algorithm with national patent technology (patent number: ZL200720037710.7) can be used, so that the circuit breaker has a rapid breaking capability, and it can quickly isolate the fault line. Take 10kV permanent magnetite network cabinet as an example from detection failure to the circuit breaker. The fault line time is less than 25 ms, which can effectively avoid the problem of cross-level trip. |
A single-phase grounding protection system with national patent technology (patent number: ZL201020178325.6) can be used, and there is no need to increase the configuration of online judgment on single-phase ground failure of small current grounding systems, and give a alarm or trip operation according to the set value. . |
It is equipped with a complete charge display device and a reliable switch position indication. |
Modular design, can be extended as needed. |
Compact compact, small size, light weight, convenient installation. |
Isolation of the fracture visual, in line with safety standards. |
The temperature measurement and temperature correction technique is used, so that the switching equipment can be reliable and stable under different environmental conditions in the country. |
