Product Description

ZN23-40.5/2000-31.5 Indoor Handcart Type Vacuum Circuit Breaker
zN23-40.5 series handcart type indoor vacuum circuit breaker for the high voltage rated 40.5kv,three-phase AC 50Hz
indoor high-voltage electrical equipment.Apply to industrial and mining enterprises,substation and transmission and distribution
systems for control and protection switching; particularly sutable for metalurgy,electric arc steel-making industries,etc.
frequent operation required,as a control and protection equipment.
ZN23-40.5 Series meet GB1984-89<ACHIGH VOLTAGECTRCUTTBREAKER>Standards.

AMBIENT CONDITION
1.the ambient temperature:-40C-+40C;
2.the alttude:≤1000M;
3. Relatve humidity: daiy average value is not greater than
g5%,monthly average is not greater than 90%;
4.The surounding air is not corrosive and fammable gas,
steam and other significant polution;
5.Earthquake intensity:≤8 degree.

Product feature
1. The vacuum arcing chamber of this VCB is of middle sealed-in longitudinal magnetic field type. The main shaft, opening
spring and buffer are all installed on the framework. There are 6 pieces of insulator switch fixed with stable and moving
trestles , then the vacuum arcing chamber are installed between the stable and moving trestles. The main shaft connects
with moving conducting bar of vacuum arcing chamber through crutch arm of insulating bar. Two pieces of insulation bars
connect two ends of stable and moving trestles to form a whole so as to improve the rigidity.
2. When the stable and moving contact open by the performance of operation mechanism, the arc in vacuum occur between contact, then extinct when the current reach at zero. Due to the special contact structure, during the arcing period, there is longitudinal magnetic field between contact so that arc lies evenly on the surface of contact and maintain a low arc voltage; in Vacuum arc-extinction chamber, the medium intensity recover at high speed, as well as small arc power and electrocorrosion ratio after arc extinction, thus to improve the breaking capability on short-circuit current and electric life.
3. The VCB applies to rigorous occasions such as high altitude and frequent operation.
4. As long as the VCB accord to the mechanical characteristics, the client may select adaptable electromagnet or spring
operation mechanism according to special situation.
