Introduction
In order to standardize the application of 10kV~35kV voltage level standardized relay protection devices in the power system, unify the technical requirements and test of the device
Requirements such as inspection methods and inspection rules to achieve the standardization of protection device installation dimensions, plug-in layout, terminal definitions and connectors of different manufacturers,
This standard is specially formulated to improve the convenience of equipment production, commissioning, operation and maintenance.
This standard considers that although the automatic backup device of the backup power source is a safety automatic device, the backup power of the voltage level of 10kV~35kV
The application of the automatic source input device is the same as the relay protection device, so it is included in the scope of this standard.
The special connector recommended by this standard adopts a new type of structural design. At present, the field application time is relatively short, so it is used as a data
Appendix, no mandatory requirements.
This standard proposes a standardized relay protection device installation size, plug-in layout and terminal definition scheme. To meet differentiated needs, each
Based on the technical requirements of this standard, power grids, power plants and different power users formulate industry standards or enterprise standards that meet their own requirements.
35kV and below standardized relay protection device
General technical requirements
1 Scope
This standard specifies the technical requirements and test methods for 10kV~35kV standardized relay protection devices (hereinafter referred to as devices) in substations.
Laws, inspection rules, and completeness, quality assurance, and other requirements for marking, packaging, transportation, storage, and supply.
This standard applies to lines, sections (mother couplers), station transformers, ground transformers, capacitors and
Microcomputer-based relay protection devices and safety automatic devices such as reactors are used as the basis for the design, manufacture, test and operation of such devices.
Similar devices installed on other occasions can be implemented by reference.
