Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 26217-2010 "DC voltage measurement device for high-voltage DC transmission systems", and is in line with GB/T 26217-2010
The main technical changes are as follows.
--- Change "800kV" to "1100kV", and modify the second paragraph to "This standard applies to DC installed at ± 1100kV and below
Voltage measuring device, typical arrangement is DC pole bus, double twelve pulsating converter valve group midpoint (if applicable) bus, neutral
Busbar, ground electrode lead and bridge arm circuit of flexible DC transmission system. "(See Chapter 1, Chapter 1 of the.2010 edition);
--- Deleted the terms "step response", "amplitude", "phase", "cutoff frequency", "IP code", "protection level" (see section
Chapter 3);
--- Change the "rated DC voltage" to "rated primary voltage" and modify the corresponding definition (see 3.8, 2.12 in.2010);
--- Added the term "maximum continuous operating voltage" (see 3.9);
--- Modify the chapter title "Ratings and performance requirements" to "Rated values" (see Chapter 5, Chapter 5 of the.2010 edition);
--- Modify the "rated DC voltage" to "rated primary voltage" and increase the voltage value "1100" (see 5.1, 5.1 of the.2010 version);
--- Revised "Nominal DC voltage value" to "Maximum continuous operating voltage" and modified the voltage value (see 5.2,.2010 version
5.2);
--- Change the secondary output corresponding to the rated primary DC voltage to "2D41H" to "3A98H" (see 5.4,.2010 version 5.4);
--- In Table 1, the "rated DC voltage" was changed to "the highest continuous operating voltage", and the corresponding voltage value was modified, adding "1100" and
The corresponding withstand voltage value (see 5.5.1, 5.5.1 of the.2010 version);
--- take the content of the standard accuracy level as "5.6 accuracy level of the entire voltage measurement device" (see 5.6, 5.6 of the.2010 version);
--- Part of the "performance requirements" as the content of Chapter 5 (see 5.7 and 5.8, 5.6 of the.2010 version);
--- "150 × 10-6" was modified to "250", and "(including gas density relay, pressure indicator and temperature indicator)" was deleted (see
6.1.1, 6.1.1 of the.2010 version);
--- In Table 3, the value of "static load resistance of primary circuit terminals" is re-specified (see 6.1.1, 6.1.1 of.2010 version);
--- Adjust the "6.8 nameplate" to "8 nameplate";
--- Removed "installation requirements" (see Chapter 7 of the.2010 edition);
--- Re-specify the type test items (see 7.3,.2010 version 8.3);
--- Change "-25 ℃ ~ 75 ℃" to "-40 ℃ ~ 85 ℃" (see 7.3.8, 8.3.7 of the.2010 version);
--- "The measured DC voltage voltage division ratio should meet the requirements of accuracy level" is modified to "Measured DC voltage voltage division ratio and rated voltage division ratio
The error should meet the requirements of 5.6. "(See 7.3.8, 8.3.7 of the.2010 edition);
--- Use the response time content of "performance requirements" as the criterion for transient response tests (see 7.3.9,.2010 version 5.6);
--- Use the frequency requirements of "performance requirements" as the criteria for frequency response tests (see 7.3.10, 5.6 of the.2010 version);
--- Re-specify routine test items (see 7.4, 8.4 of the.2010 edition).
