AL109Transformer parameter test
Implementation of standards.
JB／T501－91、GB1094－96
A, main function and characteristics:
Transformer empty the load exhaust a parameter test instrument and used for measuring transformer of empty carry and load to exhaust characteristic, the product adopts high curacy electric resistance a sample, the single slice machine carries on a data processing, 12 A/D conversion machine, have a data processing quickly, accurate degree Gao, measure function is strong, instrument adopts whole Chinese interface Chinese characters to show, operate simple and clear, passing a front-panel type a printer can print a diagraph data to carry on analysis, the instrument has RS232 communications to connect, can carry on an operation through a calculator, control measure, the input and output is various parameter, calculator software function overall, interface operation amity, can all diagraph datas carry on covariance, analysis and store and print into you need of various statement.
Two, technique index sign:
While don'ting circumscribe with each other a feeling machine:
1.Measure scope:
The electric voltage measures scope:0 V～500 Vs
The electric current measures scope:0 A～5 As
When COS φ =0.1~1, the power measures scope:0 W～2500 Ws
The frequency measures scope: The 45 Hz～65 Hz(circumscribe PT, CT can expand to measure scope)
2.Error margin scope
Electric voltage:050 Vses ofＶ～, ± 0.2% Fses; The 50 V～500 Vs, opposite error margin ≤ ± 0.2%
Electric current: The 0 A～1 A, ± 0.2% Fses; The 1 A～5 As, opposite error margin ≤ ± 0.2% powers: The 0 W～50 Ws, ± 0.3% Fses; The 50 W～2500 Ws, opposite error margin ≤ ± 0.3%
Frequency: The whole quantity distance absolute error margin ≤ inside the scope 0.05 Hz.
