Abstract

Claims (27)

1. A hydraulic fracturing system for fracturing a subterranean formation, comprising:

a primary switchgear, arranged on a support structure, the primary switchgear electrically coupled to a power source to receive electrical power from the power source;

a secondary switchgear, arranged on the support structure, the secondary switchgear positioned separately from the primary switchgear and within an enclosure, the secondary switchgear receiving an electrical input from the primary switchgear and including a plurality of feed connections for supplying the electrical power to a plurality of fracturing equipment; and

support equipment, arranged on the support structure, the support equipment providing one or more services to at least the secondary switchgear,

wherein at least one of the primary switchgear or the secondary switchgear is a single-bus power distribution system, the single-bus power distribution system comprising:

a single common high amperage bus receiving energy from one or more generators of the power source at one or more main breakers, the single common high amperage bus distributing the electrical power to a feeder circuit, the single common high amperage bus is rated for at least 2000A.

2. The hydraulic fracturing system of claim 1 , further comprising:

a walkway arranged proximate the primary switchgear, the walkway extending along at least a portion of the support structure and providing access to a door of the enclosure housing the secondary switchgear.

3. The hydraulic fracturing system of claim 1 , wherein the support equipment includes at least one of HVAC equipment, a control power transformer, a battery, or external controls.

4. The hydraulic fracturing system of claim 1 , further comprising:

a cable routing area positioned to extend from the primary switchgear to the secondary switchgear, the cable routing area being predetermined and consolidating one or more cables utilized to transmit the electrical power from the primary switchgear to the secondary switchgear.

5. The hydraulic fracturing system of claim 1 , wherein the support structure includes at least one of a trailer, a skid, or a truck.

6. The hydraulic fracturing system of claim 1 , wherein the enclosure is climate controlled.

7. The hydraulic fracturing system of claim 1 , wherein a length of the support structure is less than or equal to a length of an associated support structure of one or more components of the hydraulic fracturing system.

8. The hydraulic fracturing system of claim 1 , wherein the single common high amperage bus is rated for 3000A.

9. The hydraulic fracturing system of claim 1 , wherein the support structure includes a feed connection bulkhead to receive the electrical power from the power source.

10. An electrical distribution system for providing electrical to hydraulic fracturing equipment, comprising:

a primary bus, arranged on a support structure, electrically coupled to at least one generator, the at least one generator providing electrical power to a breaker coupled to the primary bus, the breaker also arranged on the support structure; and

a secondary bus, arranged on the support structure, electrically coupled to the primary bus via at least one cable,

the secondary bus being positioned within an enclosure and including a plurality of feed connections for supplying the electrical power to at least one piece of the hydraulic fracturing equipment,

wherein the secondary bus comprises a single-bus power distribution system having a single common high amperage bus receiving the electrical power from the at least one generator at one or more main breakers and distributing the electrical power to a feeder circuit, the single common high amperage bus is rated for at least 2000A.

11. The electrical distribution system of claim 10 , wherein the support structure includes at least one of a trailer, a skid, or a truck.

12. The electrical distribution system of claim 10 , wherein the enclosure is climate controlled and positioned separately from the primary bus.

13. The electrical distribution system of claim 10 , wherein a length of the support structure is less than or equal to a length of an associated support structure of one or more components of the hydraulic fracturing system.

14. The electrical distribution system of claim 10 , wherein the single common high amperage bus is rated for 3000A.

15. The electrical distribution system of claim 10 , wherein the support structure includes a feed connection bulkhead to receive the electrical power from the at least one generator.

16. The electrical distribution system of claim 10 , wherein the at least one piece of the hydraulic fracturing equipment includes at least one of HVAC equipment, a control power transformer, a battery, or external controls.
