Cooling system for electrical equipment

A method of servicing electrical equipment in a cooled electrical conduction network comprising:

• an electrical network divided into at least a first conductive section and a second conductive section, each of the first and second conductive section being connected to a respective electrical equipment having superconductive material that performs a respective operation during use and a coolant network for maintaining the temperature of a coolant in each of the first and second conductive section;
• wherein the electrical equipment and at least one of sections of the coolant network corresponding to one of the first and second conductive sections are housed in one of section enclosures;
• the coolant network comprising a coolant interface located between each of the first and second conductive section;
• wherein the electrical equipment is superconducting electrical equipment and the coolant interface is housed in an intermediate enclosure that is isolated from the section enclosures in the electrical conduction network;
• the method comprising the step of thermally isolating the first conductive sections from the second conductive section at the coolant interface.

A cooled electrical conduction network comprising:

• an electrical network divided into two or more conductive sections, each of the two or more conductive sections being connected to a respective electrical equipment having superconductor material that performs a respective operation during use;
• and
• a coolant network for maintaining the temperature of a coolant in each of the two or more conductive sections,
• wherein the electrical equipment and each of sections of the coolant network corresponding to each of the two or more conductive sections are housed in each of section enclosures of the cooled electrical conduction network, the coolant network comprising a coolant interface located between each of the two or more conductive sections,
• wherein the coolant interface is housed in each of intermediate enclosures that is isolated from the section enclosures in the cooled electrical conduction network, and
• wherein the coolant interface comprises a coolant valve for isolating one section of the coolant network from other sections of the coolant network.
