This section GB/T Part 1,110,066, and used in conjunction with Part 1.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section instead of GB/T 10066.11-2005 "electric heat apparatus test methods Part 11. Buried arc furnace", and GB/T 10066.11-2005 compared to the main technical changes are as follows.

a) "3 Terms and definitions", according to IEC 60683:2011, adds the following terms.

--- Apparent power (see 3.2);

--- Bottom electrode (see 3.3);

--- Cold test (see 3.5);

--- Dead (see 3.6);

--- Furnace power consumption (see 3.9);

--- Heat test (see 3.12);

--- Reactive power (see 3.16);

--- Reactive power compensation (see 3.17);

--- Rectifier (see 3.18);

--- Semiconductor inverter (see 3.19);

--- Smoothing reactors (see 3.20).

Delete the following terms.

--- Furnace (see GB/T 10066.11-2005 in 3.3);

--- Primary asymmetry coefficient (see GB/T 10066.11-2005 in 3.11);

--- Cooling water flow (see GB/T 10066.11-2005 in 3.15).

b) increase the Chapter 4. Characteristics of submerged arc furnace system.

This section identical with IEC 60683:2011 "Industrial electric equipment submerged arc furnace test methods" (in English).

Consistency correspondence between this part of international documents and normative references of our files are as follows.

--- GB/T 10066.1 Test Method for electric devices - Part 1. General section (GB/T 10066.1-2004, IEC 60398:1999, MOD)

--- GB 5959.2-2008 Safety of electric devices - Part 2. Particular requirements for arc furnace apparatus (GB 5959.2-2008, IEC 60519-4:2006, IDT) for ease of use, the IEC 60683:2011, this section also made the following editorial changes.

--- Modify the standard name, "Industrial electric equipment submerged arc furnace test methods" to "Test methods for electroheat installations - Part 11. submerged arc furnace", the English name of the corresponding changes.

1 Scope

GB/T 10066 in this section according to the rated power level of the main parameters of submerged arc furnace and the main operational characteristics 500kVA or more, and provides test procedures, test conditions and test methods for submerged arc furnaces.

This section applies to a single electrode or multiple electrode submerged arc furnace.

To further determine the technical and economic assessment of submerged arc furnace, additional testing may be necessary.

Some semiconductor inverter control by a special furnace equipment, such as a controlled rectifier or controlled AC converter test by GB/T 3859.1 regulations.
