Annotation

The control system of high-voltage switches at one of the substations of the branch of JSC “Grid Company” Buinskie Power Networks is presented in the work. The block control circuit of switching devices from the automated workplace is described. Its specific blocks with the help of which the whole process of switching of high-voltage switches in the switchgear – 10, 35 kV is performed are provided.

An explanation of the collection and transfer of information from intelligent electronic devices to the switchgear drive, transmission of control commands, protocol conversion and data exchange with higher levels of automated systems is given.

Advantages of the remote control system for 6-35 kV electrical apparatus are shown on the example of the 110/35/10 kV “Verkhny Uslon” substation of the Tatenergo system.

The system of remote control of switchgear during its repair and in case of other emergency situations is opened on the example of one of the substations 110/35/10 kV of the Republic of Tatarstan.

There are schemes KRUN-10, KRUN-35 kV with an illustration of the positions of electrical apparatus, combined with video surveillance of the state of the switch of a certain cell and the position of the earthing switch of a separate switching device.
