ZW32-24FG Outdoor High-Voltage Vacuum Circuit Breaker Product Introduction

1. Product Brief Introduction

The ZW32-24FG series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor switchgear for three-phase AC 50Hz with a rated voltage of 24kV. It is suitable for switching various types of properties of load current and frequent operation occasions, and is applicable to power supply and distribution equipment and construction of urban network, rural network, mine, railway and other places.

This product is successfully developed based on absorbing foreign advanced technology, relying on domestic raw materials and craftsmanship, and adapting to China's national conditions. Compared with similar international products, it has the advantages of miniaturization, maintenance-free, intelligentization, etc. At the same time, the product is pollution-free to the surrounding environment and is a green and environmentally friendly product.

In recent years, with the continuous expansion of China's urban power grid and the rapid growth of power load, the original 10kV voltage level distribution network has exposed problems such as high power supply voltage, high line loss, and difficulty in meeting the voltage quality requirements due to the characteristics of long power supply lines and large line capacity in rural power grids. Therefore, it is imperative to adopt 24kV voltage level power supply to increase power supply capacity, ensure voltage quality, reduce power grid energy loss, and save power grid construction costs.

The circuit breaker complies with GB1984-2003 "High-Voltage AC Circuit Breakers", DL/T402-2007 "Technical Conditions for Ordering High-Voltage Circuit Breakers" and DL/T403-200012V ~ 40.5kV "Technical Standards for Ordering High-Voltage Vacuum Circuit Breakers".
