Control-measuring unit of electrochemical protection of underground facilities

摘要

The invention relates to a system for electrochemical protection of underground structures against corrosion caused by aggressive influence of ground or stray currents, and more particularly to the control and measuring points on underground communications, designed to measure the potential on the steel pipes. headgear design provides high protection against unauthorized access points due to the fact that the lock to allow access to the terminal block located in a remote place from the bottom to the point 2. A member of staff with a key lock on the lid 2, and turns around his headgear fastening axis, thereby opening up free access to the terminal board 5. The horizontal face 2 helmet has dimensions sufficient to accommodate at its free terminal 5 square meter for pro duction necessary measurements and journal entries. At the end of the headgear is reset and lockable. The area of ​​the side faces 3.4 are sufficient for placing them on the number of control points, the dimensions of which are sufficient for it to be seen from afar, including from a helicopter. The claimed apparatus is characterized manufacturability, reliability against unauthorized access and usability during operation.
