Abstract

The invention provides a cable tray structure for nuclear power plant reactor top cable arrangement. The cable tray structure comprises a support column (5), a flexible cable arrangement device (6), a cable connecting plate (8), a cable tray (9), a guide rail structure (10), a tray moving limit device (11), a gear rack pair (12), a cable tray mounting seat (17), a base plate (21), a spacer (22), a connecting pair (23), a connecting pin (26), a limit device (27) and a base plate rotating device (29). The weight of an integrated reactor top component is reduced, the risk of lifting the structure of the integrated reactor top component is relieved, the distance between the gravity center of the integrated reactor top component and a geometric center is shortened, and transformation of different positions of the cable tray is ensured in running of the cable tray and refueling peroration.

Description

technical field [0001] The invention belongs to the technical field of design of nuclear reactors in nuclear power plants, and in particular relates to a cable bridge structure for arranging cables on the reactor top of the nuclear power plant. Background technique [0002] The nuclear reactor is located in the containment of the nuclear power plant and is one of the key equipments of the nuclear steam supply system. Among them, the integrated reactor roof assembly is a major device on the reactor that integrates several equipment or components with different functional requirements on the reactor roof to simplify the refueling operation of the reactor. The main function of the integrated reactor roof assembly is to realize the overall lifting, transfer and storage of the reactor roof assembly through the integrated operation with the top cover of the reactor pressure vessel during the reactor shutdown and refueling period. The centralized arrangement of the cables greatly s...
