Introduction

GB/T 16895 proposes safety protection and electrical equipment for medium and low-voltage electrical devices in general devices or places and special devices or places.

selection, installation and inspection and functional requirements. It has positive guiding significance for the safe use of low-voltage electrical devices.

GB/T 16895 is planned to consist of six parts.

---Part 1: Basic principles, general characteristics assessment and definitions. Determining safety for the design, installation and inspection of low voltage electrical installations rules to avoid damage to people, livestock and property during the installation and use of low-voltage electrical installations, and to ensure the correct installation of electrical installations.

Install and run correctly.

---Part 4: Safety protection. Contains sub-sections 4-41, 4-42, 4-43, and 4-44, which respectively describe the installation and use of electrical devices.

Specific safety measures are proposed for four types of electrical hazards that may occur during the process. electric shock, thermal effects, overcurrent, voltage interference and electromagnetic interference.

Protection requirements.

---Part 5: Selection and installation of electrical equipment. Contains subparts 5-51, 5-52, 5-53, 5-54, 5-55, 5-56, which are intended to be based on the equipment usage function and installation environment have a significant impact on the wiring system, isolation, switching and control and monitoring electrical appliances, grounding configuration and protective conductors, Proposal for the selection and installation of low-voltage power generation equipment, auxiliary equipment, lamps and lighting fixtures, safety facility power supplies and other electrical equipment Require.

---Part 6: Inspection. Put forward specific requirements for the preliminary inspection and periodic inspection of electrical devices to provide long-term safe operation of the equipment.

Quality assurance.

---Part 7: Requirements for special devices or locations. Including 7-701, 7-702, 7-703, 7-704, 7-705, 7-706, 7-710, Subparts 7-711, 7-712, 7-713, 7-714, 7-715, 7-717, 7-722, 7-740, and 7-753 are for various special devices or locations.

Put forward safety protection, equipment selection and installation requirements accordingly. Each sub-part of Part 7 is relatively independent and there is no direct connect.

---Part 8: Functional aspects. Make functional requirements for electrical installations. Currently, only subpart 8-1 covers electrical installations.

requirements for energy efficiency.

Part 1, Part 4, Part 5, Part 6 and Part 8 mentioned above are general parts, and most of the requirements are applicable to Part 7: However, in special devices and places, Part 7 proposes some provisions and requirements that supplement, modify or replace the general parts.

This document optimizes the use of electrical energy by considering proper design and installation. Reach minimum while maintaining safe operation of electrical installations Energy consumption, and achieving optimal power utilization is a common requirement for the design process. In addition to the many parameters taken into account in the design of electrical installations, What is more important is to reduce the internal losses during the operation of the power distribution system. Electrical installations are designed taking into account the user, power supply and utility requirements.

In addition to new installations, this document also applies to the renovation of existing electrical installations to significantly improve their energy efficiency.

The optimized utilization of electric energy is energy efficiency management based on electricity price, electricity consumption and real-time adjustment. Full course in electrical installations During the life cycle, efficiency is tested through measurement. Improvements and improvements in energy efficiency can be achieved by redesigning or replacing equipment. the purpose is Design and install an efficient electrical installation based on acceptable investment, and perform power management processes to meet user needs. this document Various energy efficiency measures have been introduced to ensure that the energy consumption of the electrical device itself is reduced on the basis of improving energy efficiency. This document is a priority it provides guidance on measures to consider return on investment, namely saving electricity, reducing electricity costs and recovering investment on schedule.

This document introduces the requirements for the design and energy efficiency assessment of electrical installations within the framework of the ISO 50001 energy efficiency management approach.

Requirements, suggestions and methods to obtain the most durable equivalent functions and the most acceptable balance between power utilization and economy with the lowest power consumption.

Low voltage electrical installation Part 8-1.Functional aspects of energy efficiency

1 Scope

This document provides additional requirements, measures and recommendations for the design, installation, operation and inspection of various types of low-voltage electrical installations, including the use of locally developed electricity and energy storage to optimize the overall efficient use of electrical energy.

This document introduces the assessment of energy efficiency (EE) during the design, installation and operation of electrical installations within the framework of an energy efficiency management system.

Requirements, recommendations, and methods to obtain the most durable equivalent functionality and the most acceptable balance of power utilization and economy with the lowest power consumption.

Within the scope of GB/T 16895 (all parts) these requirements, recommendations and methods apply to new installations and modifications to existing installations.

This document applies to electrical installations or systems in buildings and not to products. Energy efficiency of products and their operating requirements stipulated by relevant product standards.

If other standards provide specific requirements for specific systems or device applications [such as manufacturing systems covered by ISO.20140 (all parts)] requirements, these requirements supersede the corresponding content of this document.

This document does not specifically address building automation systems.

This group of energy efficiency publications is mainly used for the energy efficiency standards for low voltage electrical installations mentioned in Chapter 1, but is also used by technical committees according to Standards are prepared based on the principles specified in IEC Guide 119 and IEC Guide 118.
