Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 11805-2008 "Hydraulic generating units automation components (devices) and their systems basic technical conditions", and
Compared with GB/T 11805-2008, the main technical changes are as follows.
--- Added "terms and definitions" (see 3.2, 3.3, 3.11);
--- Increased the principle of speed setting for pumped storage reversible units or special cases, and modified the electrical of "secondary overspeed contacts"
Fixed value (see 3.6, 3.4 of the.2008 edition);
---Modified the electrical output requirements of components (see 5.1.1.12, 5.1.1.12 of the.2008 edition);
--- Increased the frequency measurement resolution requirements of the residual voltage measurement method of the electrical speed signal device (see 5.1.2.7,.2008 edition)
5.1.2.7);
--- Increased the level requirements for different measurement positions of temperature measuring resistors (RTD) (see 5.1.2.14, 5.1.2.14 of.2008 edition);
--- Revised the relevant requirements for electric valves (see 5.1.2.23, 5.1.2.23 of the.2008 version);
--- Revised the relevant requirements of the vibration (swing) monitoring device (see 5.1.2.25, 5.1.2.25 of the.2008 edition);
--- Revised the relevant requirements of the generator air gap monitoring device (see 5.1.2.26, 5.1.2.26 of the.2008 edition);
--- Revised the relevant requirements of the generator partial discharge monitoring device (see 5.1.2.27, 5.1.2.27 of the.2008 edition);
--- Revised the relevant requirements for the large axis axial displacement monitoring device (see 5.1.2.28, 5.1.2.28 of the.2008 edition);
--- Increased requirements for early smoke detection systems for air sampling (see 5.1.2.37, 5.1.2.37 of the.2008 edition);
---Modified the output accuracy level of the transmitter (see 5.1.2.41, 5.1.2.41 of the.2008 version);
--- Increased the relevant requirements for the unit's bearing external circulation cooling device (see 5.2.2,.2008 version 5.2.2);
--- Removed the relevant requirements for phase-modulation operation in the accident shutdown condition (see 5.2.7, 5.2.7 of the.2008 edition);
--- Increased the accident shutdown signal and alarm signal of low oil pressure and low pressure position of hydraulic tank accident (see 5.2.7,.2008)
Version 5.2.7);
---Modified emergency shutdown signal and alarm signal (see 5.2.8, 5.2.8 of.2008 edition);
---Modified the description of the gas fire extinguishing system in the field test of the fire alarm system and automatic fire extinguishing system (see 7.8.6,.2008 edition)
7.8.6);
--- Added description of the field test of the shaft insulation monitoring device (see 7.8.13).
