Application Locations
First, urban power grid
It is usually necessary to use sulfur hexafluoride circuit breakers for the control and protection of power equipment in the distribution boxes, substations and other places in the urban power grid. Sulfur hexafluoride circuit breaker has characteristics of explosion protection and long service life, which can ensure normal operation of power system, reduce loss and impact of power outage, and ensure stable power supply in city. Second, the power system of industrial and mining enterprises
Industrial and mining applications typically require heavy-duty power devices that must be monitored, protected and managed using hexafluoride load switches. Hexafluoride circuit breakers have excellent protection and long service life under severe conditions of high heat, high humidity and corrosion, ensuring safe operation of equipment and improving production efficiency and economic benefits of industrial and mining equipment.
Third, the railway traffic network
A lot of power equipment, including traction transformers, traction frequency converters and so on, must be used in the railway transportation network. Sulfur hexafluoride circuit breakers are used in various applications, such as power outage protection, overload protection, etc., that ensure operation of power equipment and normal operation of railways. At the same time, the Sulfur Hexafluoride Circuit Breaker has the characteristics of compact and small size, which may adapt to the dense installation of electrical devices.
