The invention discloses a composite conductive shielding device, comprising a housing and springs. Movable top covers are arranged on the top surface of the housing, fixing mounting plates are arranged at two ends of the inside of the housing, one lateral surface of each fixing mounting plate is provided with clamp holes, insulating fixing seats are arranged on the upper surfaces of the fixing mounting plates, and an insulating slider is arranged at the bottom of each insulating fixing seat; clamp posts are pressed in when the insulating fixing seats need to be raised up, the clamp posts are retracted into bottom post slide channels, the insulating fixing seats are moved, the positions of the insulating fixing seats are adjusted by sliding, to one side, the insulating sliders in the slidechannels until the insulating fixing seats are moved to the proper clamp holes, and the clamp posts on mounting seats are extended out under the action of the springs and are clamped to the corresponding clamp holes. Compared with the traditional immobilized insulating fixing seats, the insulating fixing seats in the shielding housing herein enable various copper bars of different sizes to be mounted and fixed, and using is more flexible.
Description
technical field [0001] The invention belongs to the technical field of shielding equipment, and in particular relates to a composite conductive shielding device. Background technique [0002] Enclosed busbar is a busbar system composed of metal plate (steel plate or aluminum plate) as protective shell, conductive bar, insulating material and related accessories. Including phase-separated closed busbars, common box (including common phase separated phase) closed busbars and cable busbars, which are widely used in power plants, substations, industrial and civil power supply leads. Common box closed busbars include non-phase-separated shared box closed busbars, phase-separated shared box closed busbars and AC / DC excitation shared box busbars, which are widely used between the lead-out lines of generators below 100MW and the low-voltage side of the main transformer or factory transformers for units of 75MW and above Current transfer between the low-voltage side and the high-vol...
