Product Description

Product Description

 

VS1-12 / 1250 high-voltage indoor side mounted vacuum circuit breaker (VCB) can operate frequently or break short-circuit current multiple times within the working current range. Its mechanical life can reach 30000 times, and the breaking times of full capacity short-circuit current can reach 50 times. The VS1 series is suitable for reclosing operation with high reliability and service life. It adopts the integration of operating mechanism and VCB body. The operating mechanism adopts the spring energy storage type, which has two functions of electric and manual energy storage. When the circuit breaker works, the energy of the energy storage spring is transmitted to the linkage mechanism through the output cam, and then to the dynamic contact mechanism through the linkage mechanism.

The VS1 side mounted VCB can be designed as a fixed installation unit or a special propulsion mechanism to form a handcart unit. It can be equipped with KYN28A-12 (GZS) and other central handcart type switchgear, or XGN fixed type switchgear.

 

According to different insulation structure, The VS1 series can be divided into common insulating cylinder type and embedded pole type.

1. The common type VCB adopts vertical insulating cylinder made of insulating materials to prevent the influence of various climates, and in the aspect of maintenance, it usually only needs to clean or lubricate the operating mechanism occasionally. The conductive circuit of the main part of the common type circuit breaker is arranged in a cylindrical insulating cylinder.

2. The epoxy embedded pole type VCB adopts fixed seal pole insulation (that is, through APG process, epoxy resin is used to seal the arc chamber and upper and lower outlet ends, reducing the size of the arc chamber, and improving the weather resistance and mechanical support), high service life and maintenance free. It is suitable for frequent operation under rated current in power system or places with multiple short-circuit breaking current.
