Device for measuring electrical current, voltage and temperature on an electrical conductor made of rigid material

A device for measuring electrical current, voltage and temperature in a low voltage system, comprising:

• a contact piece for connecting to a distribution bar;
• and
• a conductor made of rigid material, wherein the conductor includes:
• two conductor sections, wherein each conductor section is formed on opposite ends of the conductor;
• an electrical resistor element disposed between the two conductor sections, wherein the electrical resistor is formed of a material having greater resistance than a material of which the two conductor sections are formed;
• an area in a region of the resistor element that is flatter than the two conductor sections and forms a depression between the two conductor sections;
• a measuring arrangement formed over the depression as a bridge between the two conductor sections, the measuring arrangement including at least one measuring device and a microprocessor, wherein the measuring arrangement has a printed circuit board and a measuring circuit and wherein the measuring circuit and a first microprocessor, which processes the signals coming from the measuring circuit are located on the printed circuit board, wherein the output signal of the at least one measuring device is fed to the microprocessor via a respective potential isolator,
• wherein the contact piece is connected to a first of the two conductor sections and includes two contact prongs that are connected to one another via a contact spring, the contact spring having first and second sections formed on opposite sides of the contact piece, and the first and second sections of the contact spring are connected via a connecting element,
• wherein the contact piece makes contact with a vertically running conductor in that the conductor with the contact piece is pushed over the vertically running conductor, so that the vertically running conductor is located in the intermediate space between the two contact prongs,
• wherein an arrangement of the conductor supplies current to switching, control, and regulating devices within a switchgear system,
• wherein the contact piece includes a first leg connected to the first of the two conductor sections and a second leg that supports the contact piece, and
• wherein the first leg and the second leg of the contact piece form a Z-shape.
