Technical field
The utility model belongs to technical field of electric power, and in particular to a kind of open-close type mutual inductance for having both protection Yu measurement function
Device.
Background technique
Current transformer, English are called " current transformer ", are called and make current transformer, its principle is
According to made of electromagnetic induction principle.Current transformer is made of the iron core and winding being closed.Its first side winding the number of turns
Seldom, it is serially connected in the route for needing the electric current measured, therefore it often has whole electric currents of route to flow through, secondary side winding circle
Number is relatively more, is serially connected in measuring instrumentss and protective loop, at work, its secondary side circuit closes current transformer always
It closes, therefore the impedance very little of measuring instrumentss and protective loop series coil, the close short circuit of the working condition of current transformer.Electricity
Current transformer is that primary side high current is converted into secondary side low current to measure, and secondary side can not open a way.
Compared with traditional mutual inductor of ribbon core, Rogowski coil has measurement range wide, and precision is high, reliable and stable, response
Bandwidth, while having measurement and relay protection function, small in size, light-weight, safety and meets environmental requirement.Based on Roche line
Circle have the characteristics that electric current can real-time measurement, fast response time, will not be saturated, almost without phase error, therefore it can be applied
In relay protection, silicon controlled rectifier, frequency control, the occasion of the signals Severe distortion such as electric resistance welding.
Existing current transformer is all that measurement and protection separate, mutual to electric current with the implementation of national smart grid
The volume miniaturization of sensor, safety in utilization require higher and higher.
Utility model content
The purpose of the utility model is to overcome defects existing in the prior art, provide one kind and have both protection and measurement function
Two kinds of mutual inductors of current transformer and Rogowski coil are combined into one by the open-close type mutual inductor of energy, the device, Rogowski coil conduct
Circuit protecting element, current transformer realize two kinds of measurement, protection functions, miniaturized structure, operation as measuring cell
Convenient, safety is good.
To achieve the above object, the technical solution of the utility model has both opening for protection and measurement function there is provided a kind of
