ZF12 -72.5/126/145 (L) GIS    Gas Insulated Switchgear

 

 

 

Brief Description

 

1.Gas Insulated Switchgear (GIS) is 3-phase AC high voltage switchgear which is used for the control, measurement, protection and switching of transmission lines. Since 1984, more than 5000 bays have been in service, some exported to Thailand, Equatorial Guinea and other countries.

 

2.ZF12 -72.5/126/145 (L) GIS contains major substation equipments, such as circuit breaker, disconnector, earthing switch, voltage transformer, current transformer and surge arrester. All components are three-phase in one closure. The GIS can be connected with incoming and outgoing line of bushing or cable, or directly with the transformer under the different connection requirements.

 

ZF12 -72.5/126/145 (L) GIS    Gas Insulated Switchgear

Main Features

 

1. The mechanism is oil/gas free, simple construction, easy maintenance and reliable operation.

 

2. The enclosure is made of aluminum alloy to ensure light weight, low temperature-rise and strong anti-corrosion..

 

3. Double sealing systems are adopted to guarantee high reliability in gas tightness and the annual gas leakage rate is leaa than 0.5%.

 

4. Excellent insulating, conducting and current carrying performances.

Structure of Main Components

 

1. Circuit Breaker

The circuit breaker uses a compact three-phase box an dthree-phase conductor coplanar arrangement. Th ecircuit breaker with self-arc extinction principle, greatly reduce th eoperating power, with CT30 spring operating mechanism. Three-phase mechanical linkage breaking ability can braker 20 times in full capacity.

 

2. DS-ES three-position switch (DS-ES)

The DS-ES three position switch is box of tri-pole structure. The three position mechanism lead the middle contact to move, achieving DS combining, ES combining an dDS-ES combining three electrical conditions. The ES of three-position for preparing, is the security protective ES.

 

3. Intelligentize HGIS

Use "high voltage equipment plus optics current transformer plus intelligent terminals plus online monitoring sensors" achieving intelligent high voltage equipment.
