Advantage of Load Break Switch

Improved arc control:

The oil suppresses arc formation during switching.

Better insulation:

Reduces the risk of current leakage or short circuits.

Reliable in tough environments:

Suitable for outdoor or remote areas.

Compact and durable design:

Fewer moving parts mean fewer breakdowns.

Types of Load Break Switch

Vacuum load switch: A vacuum load break switch is a device that interrupts electrical current when activated. A load break switch can be closed manually with a switch handle or automatically with an electrical signal.

Sf6 load switch: Sf6 gas is used as an arc extinguishing and insulating medium in this medium voltage switchgear. In a switch, there are three functional positions: Open, closed, and ground.

Air load switch: Air is used as the dielectric and arc extinguishing medium in this load switch. It can also be defined as a switchgear that uses air as the interrupting medium. In the air break switch, the contacts open in the air, and compressed air is used to prevent arcing.

Medium voltage load switch: This is a load break switch that can handle voltages from 3 kv to 36 kv. There are various styles such as metal-enclosed outdoor type, metal-enclosed indoor type, and outdoor metal-free enclosed type.

High voltage load switch: High voltage load break switches are divided into more types. Solid-state gas-producing high-voltage load switch: Use the energy generated by arc breaking.

Low voltage load switch: This is a load break switch rated at 1 kv. There are hrc fuses, low voltage circuit breakers, switches, unloading electrical isolators, miniature circuit breakers (mcb), earth leakage circuit breakers, and molded case circuit breakers (mccb).

FAQ

Q: What is the main function of a load break switch?

A: High-voltage load switches are used to interrupt rated current and overload current. They have a clearly visible isolating break and are equipped with an electric spring mechanism for earthing switches with closing capabilities, enabling remote control.

Q: What is the difference between a breaker and a load break switch?

A: Circuit breakers are designed to interrupt the flow of electrical current in a circuit when an overcurrent or short circuit occurs ,but LBS cannot cut short circuit breakers without strong arc extinguishing device. Therefore, it is generally used in series with a high-voltage fuse to provide short-circuit protection.

Q: What is the construction of a load break switch?

A: Load break switches primarily consist of sheet steel enclosures, offering straightforward and robust construction. They incorporate epoxy insulators, lagging pins, double switch blades, forged contacts with seamless current paths, and arc quenching chambers.

Q: What is a difference between load break and non-load break elbows?

A: The construction of the load break elbow does not allow it to be connected to other elbows, but the dead break does. A dead break or “hammerhead” elbow can only be disconnected when not under load, this is because you need to actually unscrew a pin to detach it.

Q: Where does load break switch used for?

A: It is suitable for three-phase AC 10KV, 50HZ power systems, or used in conjunction with complete sets of distribution equipment, ring network switchgear, modular substations, etc. It is mostly used in area network construction and reconstruction projects, industrial and mining enterprises, high-rise buildings and public facilities, etc. It can be used as a ring network power supply or terminal, playing a role in the distribution, control and protection of electric energy.
