High Voltage Switchgear Panel

Description

The high-voltage switchgear panel is a complete power distribution equipment for 3.6~24kV, three-phase AC50/60Hz, single bus and single bus section system. Mainly used for power transmission of small and medium generators in power plants; power reception and transmission of power distribution in factories, mines and enterprises and substations in power systems, as well as the start of large high-voltage motors, to control, protect and monitor systems. This switchgear complies with IEC298 and GB3906-91 standards. In addition, it can be used with VS1 vacuum circuit breakers, and can also be used with ABB's VD4, Siemens' ZN65A, Siemens 3AH5, and GE's VB2. Power distribution equipment with good performance.

In order to meet the requirements of wall-mounted installation and front-end maintenance, the switch cabinet is equipped with a special current transformer so that the operator can perform maintenance and inspection in front of the cabinet.

KYN61-40.5 removable AC metal-clad switchgear applies to 40.5kV, 3 phase, AC and 50/60Hz electrical power network for receiving and distributing power energy and also for control, monitor and protect ion. It is applicable in general power system and occasions with frequent operation. The product conforms to GB3906: 3~35kV AC Metal Enclosed Switchgear, IEC60694 & GB/T11022: The common technical clauses of HV Switchgear and controlgear Standard, DL/T404-1997: Order Technical term of Indoor AC HV Switchgear and IEC62271-200 1~52kV AC Metal Enclosed Switchgear and controlgear standard.

KYN61-40.5 switchgear is three phase AC 50 Hz,rated voltage of 40.5 KV indoor power distribution equipment.As power plants ,substations and industrial distruction of electric energy only ,and has a circuit implementation of control,protection and monitoring function .
