Hv Vacuum Load Switch

DAYA Hv Vacuum Load Switch Details

AC H.V Vacuum Load Switch Summary It is a three phase H.V switch equipment of 12kV.50Hz for breaking or closing load current.no-load transformer cablecharging current and closing shortcircuit current.The load switch with earth switch can bear short-circuit current.

HVL/cc Switch Interrupting Current Rating: The HVL/cc switch is designed and tested in accordance with ANSI standards as a “load interrupter ” switch, capable of interrupting load currents up to its continuous current rating. However, per ANSI, this switch is not intended to be the main switching device.

• HVL/cc Switch Interrupting Current Rating: The HVL/cc switch is designed and tested in accordance with ANSI standards as a “load interrupter ” switch, capable of interrupting load currents up to its continuous current rating. However, per ANSI, this switch is not intended to be the main switching device.
• It is the most capable interrupter available on the market with load breaking, line dropping, and loop splitting capabilities listed below. Single Bottle Vacuum attachments add the capability of loop splitting on systems up to 230kV where the voltage drop across the open gap of the switch does not exceed 30kV.

DAYA  Hv Vacuum Load Switch Advantages

• Quick and cost effective conversion of existing switches - installation on most group-operated isolating switches
• Wide operating range - May be used for full load interruption up to 34.5kV
• Optional voltage limiter - Expands capability for transmission line charging current and transformer-magnetizing current interruption at voltages up to 72.5kV, in addition to providing 2,000 amp of loop splitting or parallel switching capability
• Long, low maintenance service life - Virtually maintenance-free; requires only an inspection every 5 years or 5,000 operations
