Abstract[English]
The present disclosure is directed to systems and methods for direct electrical heating of a fluid conduit, also referred to in one form as a tube. A fluid heating system includes a tube defining a fluid passage. The tube includes a material having a conductivity greater than 1.0 Siemens per meter (S/m) at 20° Celsius. The material is distributed along the tube and the fluid passage defines an inlet configured to receive fluid and an outlet configured to release the fluid. The system includes a first power supply, which includes a first circuit. The first circuit is configured to conduct first electric current across a first portion of the tube and the first circuit includes a first galvanic isolator between a source of the first power supply and the first portion of the tube. The first power supply is configured to heat the tube based on the first electric current.[French]
La présente divulgation concerne des systèmes et des procédés de chauffage électrique direct d'un conduit de fluide, également appelé tube. Un système de chauffage de fluide comporte un tube définissant un passage de fluide. Le tube comporte un matériau présentant une conductivité supérieure à 1,0 Siemens par mètre (S/m) à 20 °C. Le matériau est distribué le long du tube et le passage de fluide définit une entrée configurée pour recevoir un fluide et une sortie configurée pour libérer le fluide. Le système comporte une première alimentation électrique, qui comporte un premier circuit. Le premier circuit est configuré pour conduire un premier courant électrique à travers une première partie du tube et le premier circuit comporte un premier isolateur galvanique entre une source de la première alimentation électrique et la première partie du tube. La première alimentation électrique est configurée pour chauffer le tube sur la base du premier courant électrique.
