FAQs

What is a disconnector switch? A disconnector switch, also known as an isolator switch, is a mechanical switching device used in electrical systems to provide a visible break in the circuit, ensuring safe isolation for maintenance or emergency purposes. It is designed to interrupt power flow only when the circuit is de-energized, distinguishing it from circuit breakers that can interrupt load current.

How does a disconnector switch differ from a circuit breaker? While both are used for circuit interruption, a disconnector switch is primarily intended for isolation and does not have the capability to interrupt fault currents or load currents. In contrast, a circuit breaker can interrupt both normal load currents and fault currents automatically, providing protection against overloads and short circuits.

What are the main types of disconnector switches? The main types include air-insulated disconnector switches, which use air as the insulating medium; gas-insulated disconnector switches, which utilize gases like SF6 for compact and reliable operation; and vacuum disconnector switches, which employ vacuum interruption technology for high performance and minimal maintenance.

Where are disconnector switches commonly used? Disconnector switches are commonly used in power transmission and distribution substations, renewable energy plants (solar and wind farms), industrial facilities, railway electrification systems, and commercial buildings to ensure safe isolation of electrical equipment during maintenance or faults.

What are the key safety features of disconnector switches? Key safety features include visible contact separation to confirm isolation, mechanical interlocks to prevent accidental operation, earthing switches for discharging residual energy, and compliance with international standards such as IEC and IEEE to ensure reliability and personnel safety.

How are disconnector switches operated? Disconnector switches can be operated manually via handles or levers, or automatically using motorized or pneumatic actuators. Modern switches often include remote operation capabilities through SCADA systems, enhancing operational efficiency and safety by reducing the need for manual intervention.
