This is our three-station vacuum circuit breaker！

Daya DHZN-12GD indoor three-station vacuum circuit breaker is a comprehensive product integrating vacuum circuit breaker, isolation switch, grounding switch and sensor. This product is designed as a side-mounted product, in line with the trend of miniaturization, and the adaptable cabinet size is (500×1000×1800). Daya DHZN-12GD indoor three-station vacuum circuit breaker is a product suitable for use in 6-12kV medium voltage power grids. The side-mounted sealed indoor high-voltage three-station vacuum circuit breaker has excellent electrical and mechanical properties, a reliable and stable mechanism, and a long service life. The main circuit of this product uses solid-sealed poles, which not only improves the environmental adaptability and insulation reliability of the circuit breaker, but also makes the circuit breaker maintenance-free possible.

DHZN-12GD indoor three-station vacuum circuit breaker is a high-voltage switching device used to switch circuits to interrupt large currents. It consists of three vacuum chambers, each vacuum chamber contains a circuit breaker and a switch. Compared with other traditional circuit breakers, Daya DHZN-12GD indoor three-station vacuum circuit breaker has the following characteristics:

1. High reliability: The three-station vacuum circuit breaker adopts vacuum interruption technology, which does not require a medium to isolate arc and current, thus reducing maintenance and possible oil leakage or gas leakage problems. The vacuum interrupter makes the entire system more stable, and the arc is easily crushed and interrupted, ensuring the reliability and stability of the circuit and a longer service life.

2. High breaking capacity: The three-station vacuum circuit breaker can disconnect high current and high voltage level systems and handle higher breaking capacity.

High breaking speed: Vacuum circuit breakers have fast breaking speeds because they have no mechanical parts and can handle arcs quickly.

3. Multiple protection functions: The three-station vacuum circuit breaker has multiple protection functions, such as overload protection, short circuit protection, overvoltage protection, etc.

4. Multiple operating modes: The vacuum circuit breaker can be operated through various operating modes such as manual, electric, test and remote control.

5. Easy to install and maintain: The three-station vacuum circuit breaker is small in size, light in weight, easy to install, and easy to maintain and maintain.

Daya DHZN-12GD indoor three-station can be operated manually or electrically. When inspecting the high-voltage vacuum circuit breaker, please pay attention to the following points:

① When using a vacuum circuit breaker for electrical testing, the operation monitoring system must be carefully implemented first, with one person operating and one person monitoring.

② When using a vacuum circuit breaker, it must be noted that its constant voltage must be compatible with the voltage level of the electrical equipment under test, otherwise it may endanger the operator's personal safety or cause misjudgment.

③Do not expose it to the hot sun in the open air. It should be kept in a dry and ventilated place. Do not wipe or touch it with corrosive chemical solvents and detergents.

Generally, indoor three-station vacuum circuit breakers are usually installed with formal right-hand operation and reverse left-hand operation. If necessary, formal left-hand operation and reverse right-hand operation can also be customized. Daya DHZN-12GD three-station vacuum circuit breaker is an efficient and convenient product today. It is not only reliable in quality, but also affordable, and is deeply favored by consumers.
