The invention consists of a bunker to visually hide and structurally protect a cathodic protection rectifier located in an open field or urban areas where there is high incidence of vandalism. The bunker consists of a mobile element which contains a rectifier and an underground cavity structure. Besides hiding and protecting the rectifier from vandalism, the only part of this apparatus that is normally visible is a circular plaque at ground level, with a waterproof seal. Occasionally the rectifier is removed for maintenance and diagnostic purposes. In order to extract the mobile element it is necessary, but not enough, to have a magnetic or electromagnetic anchor with a great load capacity. The mobile element may only be extracted when the bolt lock located at the base of the cylinder is wirelessly activated. The cavity structure has radial plates calculated to dissipate the heat produced through the operation of the rectifier. All electric connections are hidden and embedded in concrete. Apparatus are included for measuring the electric parameters relevant to the cathodic protection and a major vibration sensor for an alarm with the possibility of being connected to networks of control systems and data collecting or cellular or satellite networks.
