Structure.
Background technique
Power plant high pressure low pressure side is total to case enclosed busbar place through walls and epoxy resins insulation plate is generally used to be isolated, and makes
It is epoxy resins insulation plate surface due to place through walls in total case enclosed busbar at total case enclosed busbar the main reason for low of insulating
Filthy and adsorbing moisture or moisture condensation, it is solvable in the dust of epoxy resins insulation plate surface when along with special and mal-condition
Property salt dissolved by moisture, formed conductive film, decline the insulation resistance of epoxy resins insulation plate surface, leakage current increase,
Generate local electric discharge of creeping；When the resistance of epoxy resins insulation plate drops to the working voltage that cannot bear route, in epoxy
The surface of insulation resin sheet, which will occur to dodge, to be ironed, and is in turn resulted in phase fault, is caused the accident, as depicted in figs. 1 and 2.For biography
The defect of system common box bus wall-punching equipment, carries out research and development upgrading to total case enclosed busbar epoxy resins insulation plate in place's through walls, designs
Novel structure through walls.
Utility model content
The purpose of the utility model is to provide a kind of novel structures through walls of common box bus, and the mother at bus place through walls can be improved
Insulation between line conductor and insulator, improves the creep distance of insulator, improves insulator and gets dirty and make moist condition, change insulator
Discharge path, cut off dew bridge between short circuit, prevent insulation decline.To achieve the above object, the utility model provides
A kind of novel structure through walls of common box bus, wears including cabinet, the wall-penetrating partition board being arranged on the cabinet wall and across described
The common box bus of wall partition and cabinet, the common box bus are divided into three groups, and common box bus described in every group is by three single-phase bus structures
At the outside of the every unidirectional bus is arranged with insulating cylinder close to one end of the wall-penetrating partition board；
The outside of common box bus described in every group is arranged with wall bushing, the set through walls close to one end of the wall-penetrating partition board
The length of pipe is less than the length of the insulating cylinder, and the wall bushing is fixedly connected with the wall-penetrating partition board.
Preferably, the wall bushing is set as helicoidal structure, and the wall bushing be bolted on it is described
It is on wall-penetrating partition board and vertical with the wall-penetrating partition board.
Preferably, be provided with gap between the edge of the wall-penetrating partition board and the inner wall of the cabinet, and it is described it is through walls every
The inner wall junction of plate and the cabinet is provided with angle steel.
Preferably, the wall bushing is fastened in the perforating on the wall-penetrating partition board, and the material of the insulating cylinder is
DMC。
Therefore, bus place through walls can be improved in the novel structure through walls of the common box bus of the utility model using the above structure
Bus-bars conductor and insulator between insulation, improve the creep distance of insulator, improve insulator and get dirty and make moist condition, change absolutely
The discharge path of edge cuts off the short circuit between dew bridge, prevents insulation from declining.
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Detailed description of the invention
Fig. 1 is the schematic diagram of the common box bus structure through walls of the prior art；
Fig. 2 is the side view of the common box bus structure through walls of the prior art；
Fig. 3 is a kind of structural schematic diagram of the novel constructive embodiment through walls of common box bus of the utility model；
Fig. 4 is a kind of side view of the novel constructive embodiment through walls of common box bus of the utility model.
Specific embodiment
Embodiment
Fig. 3 is a kind of structural schematic diagram of the novel constructive embodiment through walls of common box bus of the utility model, and Fig. 4 is that this is practical
The side view of the novel novel constructive embodiment through walls of a kind of common box bus, as shown, the utility model provides a kind of case altogether
The novel structure through walls of bus including cabinet 1, the wall-penetrating partition board 2 being arranged on 1 inner wall of cabinet and passes through wall-penetrating partition board 2 and cabinet 1
Common box bus 3, it is three groups that common box bus 3, which divides, and every group of common box bus 3 is made of three single-phase buses 31, every unidirectional bus
31 outside is arranged with insulating cylinder 32 close to one end of wall-penetrating partition board 2；The outside of every group of common box bus 3 is close to wall-penetrating partition board 2
One end be arranged with wall bushing 4, the length of wall bushing 4 is less than the length of insulating cylinder 32, wall bushing 4 and wall-penetrating partition board 2
It is fixedly connected.Wall bushing 4 is set as helicoidal structure, and wall bushing 4 be bolted on wall-penetrating partition board 2 and with wear
Wall partition 2 is vertical, and gap 5, and wall-penetrating partition board 2 and cabinet 1 are provided between the edge of wall-penetrating partition board 2 and the inner wall of cabinet 1
Inner wall junction is provided with angle steel 6, ensure that the bonding strength of wall-penetrating partition board and cabinet.The utility model passes through in each list
Insulation tube is provided on the outside of phase bus, three single-phase buses form one group of common box bus, set on the outside of each group of common box bus
Wall bushing is set, this ensure that unidirectional bus will not be contacted directly with wall-penetrating partition board, the connection of wall-penetrating partition board and single-phase bus
Place will not expose in air, play the role of duplicate protection to unidirectional bus, and wall-penetrating partition board with common box bus
