The primary functions of the HS13B isolator switch
The HS13B isolator switch is a manually switch used in power distribution equipment. Its main functions include manually connecting and disconnecting AC and DC circuits, as well as serving as an isolator switch. Below the specific functions and features of the HS13B isolator switch:
Manual connection and disconnection of circuits
The HS13B isolator switch is for power distribution equipment with AC 50Hz, rated voltage up to 380V, DC up to 440V, and rated up to 1500A (non-standard products can reach 4000A). It is used to infrequently connect and disconnect AC and circuits. This function plays a crucial role in the control and protection of power systems.
Isolation function
In addition to connecting and disconnecting circuits, the HS3B isolator switch is often used as an isolator switch. For example, the HD(S)11 series central handle isolator switch is mainly used in stations, where it does not break circuits with current, but serves as an electrical isolation. This isolation function is critical for ensuring the safety of equipment and personnel especially during maintenance and repair.
Arc extinguishing capability
Some models of the HS13B isolator switch are equipped with an arc extinguishing chamber, which safe and reliable performance when disconnecting load circuits. The arc extinguishing chamber is typically made by riveting phenolic laminated paperboard and metal arc extinguishing, significantly enhancing the arc extinguishing capability of the isolator switch. This design is particularly suitable for applications that require frequent operation or handling of high current loads.
ural features
The design of the HS13B isolator switch takes into account the convenience and safety of operation. For example, the central front lever operation isolator switch is mainly used in switch cabinets with front operation and rear maintenance. The operation mechanism is located at the front, making it easy to operate and maintain Additionally, the installation base plate of the isolator switch is made of glass fiber molding plate and bakelite plate, providing good mechanical strength and electrical insulation.
Application
The HS13B isolator switch is widely used in power distribution equipment in various industrial and commercial environments, such as power stations, switch cabinets, and boxes. Its multifunctionality and reliability make it an indispensable part of power systems.
