Electrical equipment for electrical traction rail transit car, has measuring device with intensity measuring unit for measuring intensity of current transmitted from catenary system towards roofing line arranged on mechanical support

摘要

The equipment (EE) has a single-phase disjunction apparatus (3) for isolating electrical traction devices and arranged on a mechanical support (40). A measuring device (DM) comprises an intensity measuring unit for measuring intensity of current transmitted from a catenary system towards a roofing line that is arranged on the mechanical support. The measuring device has a current measuring unit and a voltage measuring unit (34) for measuring current and voltage on the mechanical support. The voltage and intensity measuring units are housed within a single insulator (25).
