OVERVOLTAGE PROTECTION DEVICE

摘要

FIELD: electricity. ^ SUBSTANCE: overvoltage protection device includes cylindrical insulation housing in which there installed are in parallel located columns of voltage-controlled resistors, each of which is made in the form of several in-series installed sections of voltage-controlled resistors, and device for mechanical attachment of columns inside the housing. Sections of voltage-controlled resistors in columns are connected to each other electrically and in parallel, and each column of voltage-controlled resistors is arranged in insulation cover with horizontal slots for contact outputs of sections of voltage-controlled resistors. Mechanical attachment device of columns of voltage-controlled resistors inside the housing is equipped with the covers located on edges of the device, on which there fixed are columns of voltage-controlled resistors and current-conducting elements with which contact outputs of sections of voltage-controlled resistors are connected. Each current-conducting element is placed in insulation cover. ^ EFFECT: improving overall properties and improving electric strength of the design. ^ 4 cl, 3 dwg
