Fast-operating protection of busbars and outgoing connections with voltage of 6-10 kV
Relevance: protections usually used in networks with voltage range from 6 to 10 kV switch off arc circuits only if they occur in compartment of assembled busbars of switchgear assembly without time delay; short circuits occurred in compartment of current transformers and cabling place either with ti...

| description | Relevance: protections usually used in networks with voltage range from 6 to 10 kV switch off arc circuits only if they occur in compartment of assembled busbars of switchgear assembly without time delay; short circuits occurred in compartment of current transformers and cabling place either with time delay or they are not detected by operating principle. Aim: to build the protection able to detect arc circuits on busbars and in any compartments of switchgear assembly based on control of electric parameters. Results: the authors proposed the protection controlling adjunction currents from electric motors and able to selective switch-off without time delay of interphase short circuits on busbars, in cells of switchgear assemblies and on outgoing connections. The operation algorithm and sensitivity estimation are given. The field of use dependence on cable length and load power is shown. |
