FIELD: electric engineering. ^ SUBSTANCE: invention relates to method for grounding high-voltage electrode of electrodynamic grinding plant, device for method realisation, installation with device, and also application of device or plant. May be used for selective grinding of concrete or slag. Method for grounding high-voltage electrode of electrodynamic grinding plant in position of decommissioning, besides grinding plant has a technological reservoir, which in mode of operation surrounds working end of electrode so that in mode of operation it is inaccessible. The method includes the following stages. provision of grounding device for grounding high-voltage electrode by means of contact with it in zone of working end of electrode, connection of grounding device with high-voltage electrode and technological reservoir so that for grounding of high-voltage electrode grounding device automatically contacts with working end of electrode with provision of access to it, and provision of access to working end of electrode with automatic grounding of high-voltage electrode by grounding device. Method is applied with the help of device comprising high-voltage electrode and technological reservoir, corresponding to high-voltage electrode. High-voltage electrode and technological reservoir may move relative to each other so that they may be positioned at least into operational position, in which high-voltage electrode with its working end of electrode is submerged into technological reservoir and in position of decommissioning, in which working end of electrode is installed outside technological reservoir, and with grounding device, which is arranged so that when positioned into position of decommissiong it is automatically put in contact with working end of electrode for grounding of high-voltage electrode. ^ EFFECT: increased efficiency of grinding process, improved protection of personnel. ^ 27 cl, 4 dwg |
