Mixed current sensor and method for fitting said sensor

摘要

The invention relates to a mixed current sensor comprising in a case:
a current measurement device comprising a first coil;a magnetic current sensor having a second coil,electronic measurement means.;Said sensor comprises:
a first cassette comprising first linking means arranged to fix said cassette to the first coil by clip-fastening and second linking means arranged to secure the measurement device on the case;a second cassette comprising third linking means arranged to secure and fix both the magnetic sensor on the case and the first cassette and the measurement device by clip-fastening on said case.

主权项

1. A mixed current sensor in a case, the mixed current sensor comprising:
a current measurement device comprising a first coil of Rogowski type; a magnetic current sensor having a second coil wound around a magnetic circuit,
the current measurement device and the magnetic current sensor being arranged in such a way as to have a same primary circuit; electronic acquisition and measurement means of electric current; a first linking cassette comprising:
first linking means arranged to position and fix said first linking cassette to the first coil by clip-fastening; andsecond linking means arranged to position and secure said first linking cassette and the current measurement device on the case; and a second linking cassette comprising:
third linking means arranged to position, secure and fix by clip-fastening:
the magnetic current sensor on the case; andthe first linking cassette and the current measurement device on the case; the first and second cassettes comprising electric pins respectively connecting the first and second coils to the electronic acquisition and measurement means, wherein the first linking cassette and the second linking cassette are fixed to the case using a groove of a housing of the case such that the second linking means of the first linking cassette collaborates with the groove by sliding the second linking means in the groove, and the second linking cassette collaborates with the groove by sliding the second linking cassette in the groove, and thereby the first linking cassette and the second linking cassette are stacked.
