Mixed current sensor and method for fitting said sensor

摘要

The invention relates to a mixed current sensor comprising in a case:
a magnetic current sensor;a current measuring device comprising a Rogowski coil arranged in such a way that a primary circuit of the magnetic sensor corresponds to the primary circuit of said current measuring device,electronic means for performing acquisition and measurement of the electric current.;Said sensor comprises a linking cassette comprising
first fixing means arranged to position and secure said cassette by clip-fastening onto the measuring device;second fixing means arranged to position and secure said cassette and the measuring device by clip-fastening onto the case.

1. A mixed current sensor secured within a case, the case comprising a base including a first housing and a second housing, the mixed current sensor comprising:
a magnetic current sensor having a coil wound around a magnetic circuit; a current measuring device comprising a Rogowski coil arranged in such a way that a primary circuit of the magnetic sensor corresponds to the primary circuit of said current measuring device, the magnetic current sensor and the current measuring device being positioned inside walls of the second housing and being covered by a second cover on outer edges of the walls of the second housing; an electronic-printed circuit that acquires and measures electric current, said electronic printed circuit being supplied with the electric current from the coil of the magnetic current sensor, being positioned inside walls of the first housing and being covered by a first cover on outer edges of the walls of the first housing; and a linking cassette including
a first fixing arranged to position and secure said linking cassette by clip-fastening the linking cassette onto the current measuring device without soldering;a second fixing arranged to position and secure said linking cassette and the current measuring device by clip-fastening the linking cassette within the case without soldering; andelectric pins respectively connected to the Rogowski coil and to the electronic printed circuit to acquire and measure the electric current, whereinelectric tracks are securedly attached to the base and electrically soldered onto the coil of the magnetic current sensor, and the electric tracks connect the magnetic current sensor to the electronic printed circuit.
