Product Description

 

_02.jpg

      ZN63(VS1) indoor high-voltage alternatigcurrent vacuum circuit breaker has a frequency of 50Hz and a rated voltage of 12kV. It applies to the electrical equipment control and protection in industrial and mining enterprises, power plants and substations, particularty to the places needing frequent operation. It can be fixed in a switch cabinet or istalldl on a handcart.

     With stable performance and convenient istallation, it is the best choice for the control and protection of high-voltage power transmission and distribution systems.

Actuator of VS1-24

The actuator employs spring energy storage which can be done electrically or manually. When the circuit breaker is operating, the energy generated by the energy storage spring is transferred to the connecting rod mechanism through an output cam and then to the movable contact through the connecting rod mechanism. The advanced and appropriate buffer avoids bounces in breaking and reduces the impact and vibration in breaking. The actuator almost needs no maintenance or adjustment. It can operate for up to 10000 times.

Transformer capacity and fuse selection

1.The fuse can cut off a large short-circuit current in less than 10 ms and its breaking current can be up to 50KA. Thus, it can protect the transformer most efectively.

2.In terms of match between the transformer and the fuse (Table 1), the potential surge current of the fuse must be considered. Thus, fusing current of the fuse must be 1.6 times of the rated value; designer must consider possible fluctuations of other parameters of the grid and reserve margins for them. If a fuse is selected for high-voltage motor protection, designer must consider frequency of start of the high-voltage motor because frequent starts of the high-voltage motor will result in the fuse's failure when timely cooling is not available.
