Abstract
The utility model relates to a novel switch cabinet which comprises a cabinet, a but connection system, a fuse-contactor functional unit and a shield cover of a feeder cable wiring terminal. The bus connection system comprises a main bus, a branch bus, an upper static contact and a lower static contact; epoxy resin APG is sealed in an insulator; the built-in conductors of upper and lower dynamic contacts are sealed in an insulator support by the epoxy resin APG; the fuse and the contactor are arranged in the insulator support. The feeder cable connection terminal is sealed in the insulating shield cover by the epoxy resin APG. Because the epoxy resin APG technology is adopted, three components (a static contact box, the insulator support and the insulating shield cover) effectively ensured electrical insulation, so that the whole switch cabinet structure is more compact. The dimension of the cabinet is less than 1300*350*2200 (L*W*H), the area occupied is small and the installation is convenient. The switch cabinet can meet the requirements for 40Ka/0.8s internal arcing faults.
Description
Technical field
The utility model relates to a kind of cabinet, the nuclear 1E level high-voltage electrical apparatus switch cubicle that particularly a kind of nuclear power station uses.
Background technology
The 1E level F+C switch cabinet body broad that existing nuclear power station uses is generally 650mm, and floor space is big.Adopt insulating barrier to guarantee dielectric strength in the cabinet between the three-phase, bus-bar room, functional unit chamber do not reach the inside arcing fault requirement of 40kA/0.8s.
The utility model content
The utility model aims to provide a kind of compact conformation, and the cabinet width is little, and floor space is little, and built-in electrical insulation intensity height can reach the nuclear 1E level high-tension switch cabinet that the inside arcing fault of 40kA/0.8s requires.
The utility model comprises the radome of cabinet, busbar connection system, fuse-contactor functional unit, feed-out cable terminals.Busbar connection system comprises main bus bar, branch bus and upper and lower fixed contact, is encapsulated in admittedly in the fixed contact box by epoxy resin APG.The first-class built-in conductor of upper and lower movable contact is encapsulated in the insulating support admittedly by epoxy resin APG, and fuse, contactor are installed on the insulating support.The branch bus that is connected with feed-out cable is encapsulated in the insulation shielding cover admittedly by epoxy resin APG.
The utility model comprises cabinet, main bus bar, upper static contact, last moving contact, fuse, contactor, lower moving contact, following fixed contact, feed-out cable, described main bus bar, upper static contact, following fixed contact are packaged in the fixed contact box, and described upward moving contact, lower moving contact are enclosed in the insulating support admittedly, described fuse, contactor are installed on the insulating support, and described feed-out cable is installed in the insulation shielding cover.
Have conductor to connect described moving contact, fuse, contactor, the lower moving contact gone up in the described insulating support, described conductor is enclosed in admittedly and forms module in the insulating support.
Described insulating support is installed on the car of chassis.
Described insulating support, fixed contact box, insulation shielding cover are the molding for epoxy resin body.
The loop current-carrying part that connects main bus bar and outlet cable is sealed admittedly by insulating material and forms module, fuse, contactor are installed in and form functional module on the insulating support, guaranteed electric insulation effectively, whole switch cubicle more compact structure, the cabinet overall dimensions are (L * W * H) less than 1300 * 350 * 2200, it is little to take up an area of the space, is convenient to install.Owing to adopted the solid envelope insulation mode of bus and feed-out cable link epoxy resin APG in the switch cubicle, almost there be not the exposed of electrified body in the cabinet, 3 tie points of bus-bar system, fixed contact box by poured with epoxy resin shields respectively, 6 of the functional unit that fuse, contactor are formed and bus-bar system and feed-out cable patch some conductively-closed respectively and are isolated in the fixed contact box and insulation shielding cover of insulating material cast, the probability that the arcing accident is brought out is minimum, just in case take place, therefore the condition of its expansion is also very little, the effective energy of restricted internal arcing.Can reach the inside arcing fault requirement of 40kA/0.8s.
