HT SWITCHGEAR:
High Tension Switchgear
Basic Function:
- High Voltage (11KV) Controlling or Switching
- Protection (Over Load , Short Circuit, Earth Fault or any Electrical Fault
- Status reading (current ,voltage ,frequency)
Type of HT Switchgear
- VCB, LBS circuit breaker and switchboards are of optimized design considering Bangladeshi supply condition and ambient.
- The Breaker and switchboard is of compact design , sturdy construction and simple in operation with a proven motorized spring operated mechanism.
- Design ensures ease of operation, low cost maintenance and higher longevity.
- Very high quality ring main unit (RMU) suitable for highly populated city like Dhaka for multiple feeders in incoming and outgoing are used.
- Equipped with built-in mechanical interlocks for safety and the breaker compartment is so designed, that it ensures the inter chargeability with the identical circuit breakers .
- The panels are fully compartmentalized and extensible on both sides
Components
A switchgear assembly has two types of components:
- Power conducting components, such as switches, circuit breakers, fuses, and lightning arrestors, that conduct or interrupt the flow of electrical power.
- Control systems such as control panels, current transformers, potential transformers, protective relays, and associated circuitry, that monitor, control, and protect the power conducting components.
