What is a load break switch on a transformer?

The load break switch of Eaton Power Cooper system is an important component in the power system, used to achieve circuit separation, switching, and protection. They have two position and four position types, as well as variations of ring and bolt types, which correspond to different application requirements. The purpose of the load break switch of Eaton Power Cooper system: 

Transformer position: Load switches are typically used to connect and disconnect circuits between transformers and power distribution systems. They can safely cut off the power supply during maintenance, testing, or transformer replacement, ensuring the safety of personnel and equipment.

Type of load break switch:

Two position switch: This switch has two states, usually "on" and "off".

Four position switch: The four position switch includes additional intermediate positions and can provide more operating options, such as "testing" or "grounding".

Differences and advantages between ring type and bolt type:

Ring type load break switch:

Difference: The operating handle of the ring type load switch is wrapped around the switch for easy rotation for operation.

Advantages: Circular load switches are usually easy to use in structural spaces, and the design of the operating handle is easy to identify the current state. They usually have a high level of protection and can be used under the environmental conditions of the queue, such as outdoor or high humidity environments.

Bolt type load break switch:

Difference: The operating handle of bolt type load switches is usually linear and requires push pull operation.

Advantages: Bolted load switches are suitable for applications that require higher current capacity, are usually more durable, and are suitable for high current loads. They are also easy to lock and prevent misoperation.

Configuration products for load switches:

Load switches typically need to be used in conjunction with the following product configurations to build a complete power distribution system:

Transformer: used for voltage conversion and power distribution.

Bracket: used for overload and short circuit protection.

Isolation switch: used to isolate circuits and equipment for maintenance.

Cable connector: used to connect cables.

Auxiliary panel: used for power distribution and control.

Application suggestions: 

Based on the specific needs and application environment of the customer, the suggestions can be:

For applications with medium voltage or durability, the Eaton Cooper power system's circular position switch may be a good choice.

If the application requires high current capacity, the bolt type position switch of Eaton Cooper power system is a better choice.

For situations that require more operational options, consider using four position switching.

Choose together with other supporting equipment to ensure compatibility and safety of the entire power system.
