Metal Clad Cell

Metal clad Cells consisting of 3 main parts separated by a grounded metal plate and 1 auxiliary, which is switching element of withdrawable type medium-voltage switchgear system.

Fields of Application

Energy production and distribution facilities

  • Transformer stations
  • Mines
  • Cement and Petrochemical Factories
  • Iron and Steel Enterprises
  • Pump Stations
  • Airports, Ports, Railways
  • Shopping
  • Hospitals

ADVANTAGES

  • High ability to withstand current and short circuit (31,5 Ka /3 seconds)
  • Compact design with less space requirement (width 1200mm 36kv cell)
  • Fully isolated system and all grounded metal compartments are separated from each or.
  • Protection and breaker control board with various types and specifications to be able to use the property.
  • Easy withdrawable type switching devices between panels re is the possibility of change.

MECHANICAL INTERLOCKS

  • The breaker door can only be opened in a breaker test position.
  • Circuit breaker to service position cannot be taken from fixed to panels
  • Low voltage control cable cutter thing gate can be closed.
  • The door has been closed breaker to service position unless the breaker can not be taken.
  • Circuit breaker without opening the earth blade cannot be imported.
  • If the breaker is in service, soil, the blade can be closed.

ELECTRICAL INTERLOCKS

  • Cutter test and just in service position can be controlled.
  • The rear door of input cell, energy from previous Station can not be opened without cutting.
  • Rear gate of cell output, circuit breaker position can not be opened without taking tests.
  • If the breaker is in service, soil, the blade can be closed.
  • Knife can be closed without cutting energy from the previous Station soil input cell.

Security

  • Pressure relief caps in the back of A-FL, a top-FLR and IAC class.
  • All maneuvers can be done while the enclosure door is closed.
  • Has been removed the possibility of maneuvering wrong with mechanical and electrical interlocks.
  • Fully isolated system partitioning, PM, dir, and class.
  • Equipped with short-circuit earthing switch, which can close 5 E2 class.

Bar Section

Between panels enables transmission of energy, high-current and short-circuit conductors which can withstand, and Board insulator epoxy insulators and conductors bearing that secures metal part of the hive. Access to bar SECTION, when necessary, by removal of metal from cutting section casing and front plate can be done without removing curtains. In the transition between panels to the bar, the bar can easily merge to the clipboard by using apparatus in both directions of expansion are held in place

Department of Cutter

It is the section where the medium voltage switching elements (SF 6 or Vacuum Circuit Breakers, Vacuum Contactors) and the metal curtains LSC2B / PM (Partical Metal) separating the withdrawable type trolley, busbar and breaker sections that are their carriers. In accordance with requests, voltage transformers and mV fuses can be placed by car. Breakers with the same current value used in cubicles can be changed in a simple manner in terms of sustainability and energy fast. Do not force cutter so that movement of the car in service position and test position of hive secure closing curtain system is designed as a motion paving the way. Circuit breaker, spring soil with the bus, always main earthing contact. knife lock movement of soil thanks to the soil in a service position, the blade can be closed. Socket and low voltage plug system information on the status of breakers are carried to the panel. Within panel breakers, IEC62271-100 and IEC62271-200 have been tested in accordance with the standard.

Department of Control and Low Voltage Control

According to request all kinds of protection relays, control devices and measuring instruments, which are equipped with Section. An internal malfunction within the dashboard will occur in a grounded metal box to prevent damage to personnel and materials. Control and monitoring materials designed at a height that can be easily controlled. cables between panels (auxiliary contacts and interlocks) connections are easily made. Low voltage circuit breaker door or cover, and are located in dashboard mimics flow is easy to understand.

Cable Length

Different types of current, voltage transformers, epoxy case isolators with the department that provides transition breaker, soil knife, surge arrester, the capacitive isolator is a section that contains materials like salt. In case of change of instrument transformers, the assembly can be driven with a sliding structure that is fast and easy. Cables are fixed to floor panels. Necessary mechanical and electrical interlocks made/resolved if you have cable access section of the building considering size and ease of use is designed so that it can be accessed from front and rear. This security is IEC62271-200 standard specified in IAC: IAC an FLR and a type of FL is approved.
