MEDIUM VOLTAGE DISCONNECTOR SWITCHES

Medium Voltage Disconnector Switches are 3-phase devices that control the medium voltage of the electric grid through connecting and disconnecting the medium voltage of the electric circuit when the circuit is unloaded. In addition, these disconnectors are three-pole type and all poles are controlled by a mutual control mechanism and they can be mounted on a wall or a vertical plane. Furthermore, these disconnector switches are made of chassis, supporting insulators, blade-shaped movable contacts, fixed contacts, mechanical devices for connecting and disconnecting the moving contacts, lock assembly, and blade disconnectors. These disconnectors are divided into two main types according to their used environment which are indoor or outdoor. The indoor and outdoor disconnectors are also divided into subcategory according to there protection type which is fused and non-fused disconnectors. The main use of these disconnectors is meant for maintenance purposes.

Outdoor Type Disconnector Switch; Outdoor Disconnector Switches are used to disconnect the unloaded electric overhead lines in Energy Transmission Lines. Fused outdoor disconnectors are used to protect the transformers of 400kVA and above mounted on poles and de-energize them when necessary. Note: The transformer must be discharged by switching off the LV Panel before the de-energization operation.

Indoor Type Disconnector Switch; Indoor Disconnector Switches are installed between the circuit breaker and the main busbar in the open distribution system. They are used to disconnect the electric circuit after the disconnection of the circuit breaker leaving it without energy. Fused indoor disconnectors are used to protect the distribution transformer and leave it de-energized when necessary. Note: The transformer must be discharged by switching off the LV Panel before the de-energization operation.
