1. DC motor nameplate
China-made motor models are generally represented by Arabic numerals in uppercase English Chinese pinyin letters, and the format is: the first part uses uppercase pinyin letters to indicate the product code, the second part uses Arabic numerals to indicate the design serial number, and the third part uses Arabic numerals to indicate Frame code, the fourth part uses Arabic numerals to indicate the code of armature core length. Equipment factory makes equipment and machine nameplates:
Take Z2---92 as an example: Z stands for general purpose DC motor; 2 stands for design serial number, the second modification design; 9 stands for frame serial number; 2 armature core length symbol.
The meaning of the first part of the characters is as follows:
Z series: general purpose DC motors (such as Z2, Z3, Z4, etc.)
ZJ series: DC machine for precision machine tools
ZT series: wide speed adjustable DC motor
ZQ series: DC traction motor
ZH series: Marine DC motor
ZA Series: Explosion-proof safety type DC motor
ZKJ series: DC motors for excavators
ZZJ series: DC motors for metallurgical cranes
2. Electric energy meter nameplate
On the nameplate of the electric energy meter, we can see the following terms: single-phase, three-phase, active power, reactive power, etc. The registered model number is also marked on the nameplate: such as DDS×××, the first D is the pinyin prefix of "energy meter", the second D is the pinyin prefix of "single-phase", and S is "stationary type (commonly known as electronic式)" The prefix of "static" in English. "×××" represents different types of electricity meters produced by different enterprises. Our country adopts 220V voltage system, and the frequency of alternating current is 50Hz. Pay special attention to the marked current value: For example, 5(20)A means that the basic current is 5A and the maximum current is 20A.
Overloading of electricity is unsafe, and it is a hidden danger of fire. The nameplate is also marked with signs ① or ②, ① represents the accuracy of the electric energy meter is 1%, or called a level 1 meter; ② represents the accuracy of the electric energy meter is 2%, or called the level 2 meter. It is marked with the standard code, manufacturer, and factory number used by the product.
