Method and device for cleaning high-voltage carrying installation component parts
First Claim
1. A method with which a user can clean a surface of high-voltage carrying installation components or of components used in high-voltage carrying installations, the method comprising the steps of:
- a) generating, in a jet generator, a two-phase jet consisting essentially of a pressure gas and carried dry-ice particles;
b) guiding said two-phase jet to a component having a jet emitting opening to release said two-phase jet into air;
c) directing, following step b), said two-phase jet towards the component to be cleaned; and
d) maintaining a minimum distance between the user and said jet emitting opening using an electrically insulating distancing means, said distancing means disposed between and communicating with said component having said jet emitting opening and a handhold or hand rest for the user, wherein said minimum distance corresponds to a minimum distance to the high-voltage carrying component as required for personal protection or installation safety.

Abstract
A cleaning method and a corresponding cleaning device offer adequate protection to individuals, devices and installations, for cleaning component parts of installations that carry an electrical high-voltage and which are not disconnected during cleaning. Towards this end, the component parts to be cleaned are subjected to the action of a two-phase particle stream (PS) consisting of a compressed gas (DGA) serving as a carrier medium and of carbon dioxide ice particles (TP) carried therein. Possible superficial accumulations of dirt are removed from the component parts by way of low-temperature embrittlement and by the kinetic energy of the impacting carbon dioxide particles. The carbon dioxide ice particles themselves sublimate without leaving residues. A sufficiently safe distance of cleaning personnel from the high-voltage carrying insulation component parts is ensured by the provision of an electrically insulating distance mechanism (L, SFR) that is provided approximately in the form of a lance (L) or of a stream guided tube (SFR). A further increase in protection is offered by monitoring the quantity of moisture of compressed gas and/or ambient air, whereby the cleaning device is immediately shut off when predetermined limiting values are exceeded.
