Description
Technical field
The utility model is related to electrical equipment technical field, specially a kind of Combined type current transformer heat-dissipating casing.
Background technology
Current transformer principle is according to electromagnetic induction principle.Current transformer is the iron core and winding group by closing
Into.Its first winding number of turn seldom, is gone here and there in the circuit for the electric current for needing to measure, therefore it often has whole electric currents of circuit
Flow through, secondary winding turn ratio is more, is serially connected in measuring instrumentss and protective loop, current transformer operationally, its two
Minor loop is to close all the time, therefore measuring instrumentss and the impedance very little of protective loop series coil, the work of current transformer
The close short circuit of state.
Existing current transformer is during work, and caloric value greatly, can be damaged directly when using for a long time.
