ELECTRIC SERVICE LINE FOR DETECTION OF NUCLEAR RADIATIONS OF CONTROL AND PROTECTION SYSTEM OF NUCLEAR REACTOR Russian patent published in 2004 - IPC

FIELD: electrical engineering, applicable for reliable supply of low-power electric signals to the detection equipment inside the hermetically sealed zone and through the envelopes (floors) of various zones of the nuclear reactor from the detectors and sensors in the conditions of high pressure, humidity and ambient temperature. SUBSTANCE: the device has several passages of the electric service lines through the envelopes of the nuclear reactor that are series-connected by cables in flexible metal hoses. The metal hoses are sealed, and the inner cavities of the of the electric service lines are filled with a mixture of inert gases at a positive pressure. EFFECT: enhanced electric insulation resistance and reliability of electric service lines, convenience of its installation, provided monitoring of the line condition. 1 dwg
