The Type Of Vacuum Interrupter
Vacuum Interrupter
Vacuum interrupter also known as vacuum switch tube, is the core component ofhigh voltage power switch. Its main function is to cut arc off through excellent insulation of vacuum in high voltage circuit and restrain current quickly to avoid accidents and danger. It is mainly used in electric power transmission and distribution control system, also used in metallurgy, mining, petroleum, chemical industry, railways, broadcasting, communications, industrial high frequency heating power distribution system. It is characterized by energy saving, material saving, fire prevention, explosion proof, small volume, long life, low maintenance cost, reliable operation and non-pollution. Vacuum interrupter can be divided into several kinds, one for circuit-breakers and the other for load switch,for contactor,for recloser.
The vacuum interrupter for circuit breaker mainly used for substation and power grid facilities in the power sector.This series of vacuum interruper adopt ceramic insulating envelope,Cu-Cr contact materials.It has the features of large switching capacity ,high insulating levels,strong arc-quenching capability and long life,etc.Vacuum circuit breaker matched with it has the advantages of simple maintenance,no risk of explosion,no pollution and low noise,etc.,and it can be widely used in the electric power,mechanical,metallurgical,chemical and mine department,etc.,to control and protect the transmission and distribution system.
The vacuum interrupter for load switch is mainly used for end users of the power grid.This series of vacuum interruper adopt ceramic insulating envelope,and W-Cu contact materials.This kind of product has the features of small size,long life ,high insulating levels and reliable performance,etc.Load switch matched with it has the advantages of simple maintenance,no risk of explosion,no pollution and low noise,etc.,it can be widely used in the electric power,mechanical,metallurgical,chemical and mine department,etc.,to control the transmission and distribution system.
The vacuum interrupter for contactor is mainly used to frequently connect and cut off the normal working current.This series of vacuum interruper adopt ceramic insulating envelope and Cu(W+WC) contact materials with low chopping value.This kind of product has the features of reliable performance,long life ,and small size,etc.Contactor matched with it has the advantages of simple maintenance,no risk of explosion,no pollution and low noise,etc.,and it can be widely used in the electric power,mechanical,metallurgical,chemical and mine department,etc.,to control the transmission and distribution system.It is especially suitable for frequent operation of cutting off inductive load and used in the places where it is operated frequently.
The vacuum interrupter for recloser mainly used for substation and power grid facilities in the power sector.This series of vacuum interruper adopt ceramic insulating envelope,cup shaped axial magnetic field,intermediate sealing shield structure,Cu-Cr contact materials.It has the features of large switching capacity ,high insulating levels,strong arc-quenching capability and long life,etc.Vacuum recloser matched with it has the advantages of simple maintenance,no risk of explosion,no pollution and low noise,etc.,and it can be widely used in the electric power,mechanical,metallurgical,chemical and mine department,etc.,to control and protect the transmission and distribution system.
Solid Sealed Pole For Vacuum Interrupter is molded by embedding simultaneously one-time-conductive circuit parts of vacuum interrupter and switch to into the epoxy resin material insulation.The outside surface of vacuum interrupter is not influenced by external environment.External insulation capability can not be affected by the dust,moisture,small animal,condensation and contamination.The product has many advantages,such as high dielectric strength,strong weather resistance performance,one-time-ciecuit miniaturization,solid structure,high reliability and maintenance free.
