load break switch

Overview

FLN type indoor high voltage AC load breaker switch refer to international new technology and develop the switching equipment in according to the relevant standards in China’s electric power system. Its performance indicators in full compliance IEC420,694,129 and national standards GB3804-2004“3.6kV-0.5kV high voltage AC load breaker switch”GB1985-2004“high-voltage AC isolation switch and earthing switch”,GB/ T11022-1999“common technical requirements for high-voltage switchgear and control equipment standards“, This is the main switching element RMU. The load breaker switch is a collection multifunctional medium voltage switchgear of gates,sub-gate, earthing. In a fully sealed with strengthen the structure of the epoxy resin housing to filled with SF6 gas,0.05MPa , with the minimum parts to achieve the above three functions,to ensure product quality, improve reliability, maintenance-free. It can be safely run for more than 20 years in normal conditions.

Basic Functions And Features

1.Load breaker switch adapts double fracture, rotary movable contact structure, with the following three kinds of operating states: Closing,opening,earthing.
2.Using SF6 gas as an arc extinguishing and insulating medium, the main circuit seals by the upper and lower housing pouring epoxy resin, the conductive function is unaffected by external influences.
3.Good safety performance. If internal arcing occurs, the housing has an internal structure weak point, it will be rushed to open, followed by the cabinet above the shutter release arc red open air overpressure stream-oriented outside the cabinet, ensure that the switch
cabinet security checks.
4.Load breaker switch sets gates, opening, earthing switch three at one, filled with SF6 gas encapsulated in epoxy resin housing, three-position interlock,compact structure,high security and reliability.
5.Small size, light weight, maintenance-free, easy and safe to operate.
