Ürün Bilgisi

Metal clad switchgears are designed for applications where challenging environmental conditions and high electrical and mechanical durability are required. Metal clad switchgears are manufactured up to 40.5 kV. Cutting procedure is done with SF6 gas or vacuum cutters. Separation is achieved by removing the trolley cutter. Operator safety is maximized with electrical and mechanical interlocks. Metal Clad cell consists of 4 sections;

A) Low Voltage Compartment

It is the section located at the top of the cell where all kinds of protection relays, control elements and measuring instruments can be produced. Control and monitoring materials are designed at an easy-to-control height. All protection and control operations related to switching can be performed from this panel. Connections of transition cables between panels are easily made.

B) Busbar Section

It is the section where the conductors that provide energy transmission between the cells and can withstand high current and short circuit powers and the epoxy resin support insulators and sleeve insulators that fix these conductors to the body are located. Access to the busbar section can be made from the top or, if desired, by removing the front sheet metal without removing the sleeve and metal curtains from the breaker section. In the busbar transition between the cells, the expansion of the cell in both directions is easily done on site by using busbar joining apparatus.

C) Cutter Section

Medium voltage switching elements (SF6 gas or vacuum breakers) and their carrier, the drawer type trolley, is the section with metal curtains separating the busbar and breaker sections. Breakers used in switchgears with the same technical values can be interchanged quickly and simply for energy continuity. A curtain system has been designed that opens the front of the sleeves so as not to force the movement of the breaker trolley in the service position and closes safely when it is taken to the test position. The breaker trolley is always in contact with the main earth of the cell with the spring-loaded earth busbar. The status information of the breaker is carried to the low voltage panel with the socket plug system.

D) Cable Compartment

It is the section where switchgear materials such as different types of current, voltage transformers, epoxy sleeve insulators, earth knife, surge arrester, capacitive insulator that provide passage with the breaker section. The change of measurement transformers is done quickly and easily. Cables are fixed on the base of the cell with recorders. The cable compartment is designed to be accessible from the front and back, taking into account the dimensions of the building and user convenience, if the necessary mechanical and electrical interlocks are made.
