METHOD FOR SELECTING ELECTRICITY FROM LINEAR PART OF INDUCTIVE-RESISTIVE, INDUCTIVE AND RESISTIVE ELECTRIC HEATING SYSTEMS AND NODE FOR IMPLEMENTING METHOD (OPTIONS) Russian patent published in 2021 - IPC F16L53/35 F16K49/00 

FIELD: industrial heating.

SUBSTANCE: group of inventions relates to devices for heating sources of additional heat losses of industrial facilities. According to the first option, two connecting elements are installed on the heating conductor of the electric heating system at a certain distance from each other. In each of them, a heating conductor is spliced through a branching connector. An insulated electric wire is connected to the branched end of the connector, by means of which the electric potential is removed and brought into the power supply and control device of the heating element or the actuator drive. The heating element or the actuator drive is also connected to the power supply and control device. According to the second option, at the end of the heating line, a power supply and control device is installed for communication modules with monitoring and/or control devices, and/or control of a heated industrial object, at a certain distance from which a connecting element is installed on the heating conductor. The heating conductor is spliced through a branching connector. An insulated electrical wire is connected to the branched end of the connector, by means of which the electric potential is removed. The other potential is removed directly in the power supply and control device at the connection point of the phase conductor with a grounded heating tube having zero potential, or at the connection point of three-phase conductors at one point.

EFFECT: provision of power to the heating elements of sources of additional heat losses and other equipment without building an accompanying network.
