GB/T 2900.23-2008Electrotechnical terminology -- Industrial electro-heat (English PDF)

Foreword

This section GB/T 2900 Part 23.

This section identical with IEC 60050-841:2004 "International Electrotechnical Vocabulary - Part 841 electric industry." the term item number in this section and IEC 60050-841:2004 consistent.

This Part replaces GB/T 2900.23-1995 "Electrotechnical Terminology Industrial electric equipment." this section compared with the GB/T 2900.23-1995, standard large structural change, delete some terms, we added some new terminology.

This part of the National Electrotechnical Terminology Standardization Technical Committee (SAC/TC232) proposed.

This part of the National Electrotechnical Terminology Standardization Technical Committee and the National Electric Industry Standardization Technical Committee centralized common equipment.

This section is drafted. Xi'an Institute Furnace Co., Ltd. Mechanical Engineering Research Institute of Machine Productivity Promotion Center, University of Electronic Science and Technology College of Physical Electronics, Tianjin University, Chinese Academy of Sciences Institute of Plasma Physics.

1 Scope

3 Terms and Definitions

3.1 on heat and electrical energy is converted into heat in the general concept 841-21-01 each point temperature can be given space.

841-21-02

Given time its temperature is the same for each point on the surface.

841-21-03

In a direction perpendicular to the surface of the isothermal temperature difference quotient distance.

841-21-04

When matter and electromagnetic energy are not across the boundary of the physical system, increasing the total energy of the system and the work done on the system of difference.

[GB/T 2900.61-2002,111-13-35]

Note 1. How to change based on the arrival of heat from one state to another state, and when it is not caused by other changes can only be partially converted into work.

Note 2. Heat can cause an increase in energy and particle motion or other effects related to the phase transition and the like.
