Description
Technical field
The utility model relates to a kind of accessory of high-voltage ring main unit, specifically refers to a kind of side plate for high-voltage ring main unit.
Background technology
High-voltage ring main unit is for improving power supply reliability, make the user obtain power supply from both direction, usually power supply network being connected into annular.This supply power mode is referred to as ring network power supply.In industrial and mining enterprises, residential quarters, harbour and skyscraper etc. exchanged the 10KV distribution system, because load is held not quite, its high tension loop adopted on-load switch or vacuum contactor to control usually, and is furnished with the high-tension fuse protection.This system adopts ring network power supply usually, use on the high-tension switch cabinet general custom and be called ring main unit.Ring main unit is except to the power supply of this distribution substation, its high voltage bus also will be by the through current (namely through the electric current of this distribution substation bus to the power supply of adjacent distribution substation) of annular electric supply net, therefore the high voltage bus cross section of ring main unit will be according to the load current and the selection of looped network through current sum of this distribution substation, to guarantee not running overload of high voltage bus in service.Above-mentioned high-voltage ring main unit need to be bolted together to use by separate unit cabinet one by one under many circumstances side by side.And be that the side plate of the side plate of each separate unit cabinet and adjacent separate unit cabinet is installed one to one in the assembly unit process, require the projection that can not occur interfering with each other on the outer wall of adjacent side plates in assembly unit so that the outer wall energy of phase side plate fits tightly together.What be used in prior art that the side plate of high-voltage ring main unit adopts mostly is plate armature, and namely the outer wall of whole side plate is all straight, and the above does not arrange projection; Although this structure assembly unit is more convenient, but can have influence on the installation of the wire casing in the separate unit cabinet, because need cabling from primary equipment to the secondary meter chamber in the separate unit cabinet, need the wire casing of design specialized for the described cabling of safety, and wire casing can only be fixed on the inwall of side plate.Lateral plate structure of the prior art, generally can only wire casing be fixed on the side plate inwall by welding in the situation that do not increase side plate thickness, because if by the fixing wire casing of screw rod, screw head or the nut that is used for locking will protrude from the outer wall of side plate, when the separate unit cabinet carries out assembly unit, will interfere with each other between two adjacent outer walls and can not fit tightly together, obviously the workload of welding is larger, and the burr of weld easily causes point discharge, and potential safety hazard is arranged.In sum, the side plate that is used for high-voltage ring main unit in prior art when being used for the assembly unit of high-voltage ring main unit in the situation that guarantee that the outer wall of adjacent side plates fits tightly the workload that the wire casing that increased on the side plate inwall is installed, and returns simultaneously whole side plate and has caused certain potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of in the situation that guarantee that the outer wall of adjacent side plates fits tightly the workload of the wire casing installation that can not increase on the side plate inwall, does not have the side plate that is used for high-voltage ring main unit of potential safety hazard simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of side plate for high-voltage ring main unit, and it comprises the side plate main body; Described side plate main body is provided with a plurality of wire casing installing holes, described wire casing installing hole place is provided with from side plate main body outer wall caves in to inwall, described cup depth is not less than the height that wire casing is installed the spiral shell head of screw rod, and the bus of described wire casing installing hole in the high-voltage ring main unit extends to the secondary meter chamber.
After adopting above structure, the utlity model has following advantage: described side plate main body is provided with a plurality of wire casing installing holes, described wire casing installing hole place is provided with from side plate main body outer wall caves in to inwall, described cup depth is not less than the height that wire casing is installed the spiral shell head of screw rod, and the bus of described wire casing installing hole in the high-voltage ring main unit extends to the secondary meter chamber.Wire casing can not adopt welding when mounted, cooperation by wire casing installing hole and screw rod just can be completed the installation of wire casing, avoided the generation of burr phenomena, and due to cup depth be not less than wire casing and the height of the spiral shell head of screw rod be installed screw rod is passed installing hole from the outer wall of side plate after screw head can just be embedded in depressed part, the outer wall of whole like this side plate does not still have projection, can not have influence on the assembly unit between the separate unit cabinet, well solve the low problem that has potential safety hazard of installation effectiveness of wire casing simultaneously yet.
As preferably, described wire casing installing hole is six, is divided into two groups, three every group, and two groups of wire casing installing holes one horizontal one perpendicular L-shaped distributions.This structure can make wire casing extend along the edge of side plate, wire casing can be dropped to minimum to the interference of other installing component on side plate, has guaranteed that also the length of wire casing can be not oversize simultaneously.
As preferably, described side plate main body is made by aluminizing zine plate material.The aluminizing zine plate has good antiseptic and rustproof function, need not simultaneously plastic-blasting processing separately, has improved the production efficiency of side plate.
