Abstract
The utility model relates to a novel switch cabinet which is designed aiming at the problem that the installing mode of a current transformer in a conventional switch cabinet is not reasonable. The novel switch cabinet includes two L-shaped supports which are fixedly arranged on left and right side plates of a cabinet body below a bus-bar room and two preassembled installing beams which are arranged in parallel. The two ends of the preassembled beam are arranged on the L-shaped supports respectively. The current transformer is hung on the preassembled beams. The switch cabinet adopting the above technical scheme greatly facilitates the installation and maintenance of a cable on site, increases the cable installation space, guarantees the personal safety of the installation personnel, and reduces the amount of copper bars.
Description
Technical field
The utility model relates to a kind of equipment for power transmission and distribution, especially a kind of novel switched cabinet.
Background technology
At present, along with developing rapidly of network system, the quantity of various switchgears also sharply increases, and power supply-distribution system is to each switchgear fail safe, maintainable requirement also increasingly stringent.The switch cubicle current transformer does not have support on the existing market, and its mounting means adopts back loading type or lift-on/lift-off type mostly.Back loading type is that current transformer is installed on the switch cubicle rear column; Though this mounting means is convenient to the installation of current transformer; But because current transformer is loaded on the cabinet rear column, taken the first half space, place, Xiamen behind the cabinet, blocked cable bond row and made the cabinet rear space narrow and small; Be unfavorable for cable installation and maintenance of equipment, bring serious inconvenience to construction maintenance.And lift-on/lift-off type is that current transformer is fixed on the bus-bar room lower clapboard with nut, and this mounting means is difficult for carrying out current transformer by frock to be installed, and needs the artificial current transformer that holds up to install, and labour intensity is big and have personal safety hidden danger.And when the maintenance current transformer, must open bus-bar room and could change current transformer, this just needs the bus power failure just can operate, thereby has enlarged the power failure scope.
In sum, the current transformer mounting means of switchgear is unfavorable for the I&M of cable or current transformer at present, has certain hidden danger.
Summary of the invention
The utility model is unreasonable to the mounting means of current transformer in the present switch cubicle, causes the potential safety hazard that exists with maintenance inconvenience is installed, and a kind of novel switched cabinet of design makes current transformer install simple and convenient in constructing at the scene and is convenient to maintenance.
The technical scheme that the utility model adopts is: a kind of novel switched cabinet; Comprise cabinet and cabinet door; The cabinet inner region is divided into bus-bar room, handcart chamber, cable chamber by dividing plate, it is characterized in that: comprise that two L type supports are fixedly installed in respectively on the left and right side plate of bus-bar room below cabinet, also comprise two prepackage mounting rails that laterally arrange; Prepackage mounting rail two ends frame respectively are loaded on the L type support, and current transformer is lifted on the prepackage mounting rail.
Adopt the switch cubicle of above technical scheme,, reserved the space, greatly made things convenient for installation, the maintenance of on-site cable, strengthened the cable installing space for the switch cubicle bottom because current transformer is lifted on the prepackage mounting rail.L type support and prepackage mounting rail are simple in structure, and general ability is strong, are convenient to produce in batches and install, and have guaranteed the personal safety of installation personnel, reduce the copper bar consumption, effectively economize on resources.
Description of drawings
Fig. 1 is current transformer and prepackage mounting rail sketch map.
Fig. 2 is the utility model L type supporting structure sketch map.
Fig. 3 is a sketch map in the switch cabinet.
Fig. 4 is that the utility model current transformer is installed the partial structurtes sketch map, and wherein 1 is the prepackage mounting rail, and 2 is L type support, and 3 is current transformer, and 4 is left plate, and 5 is right plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The novel switched cabinet of this kind; Comprise cabinet and cabinet door; The cabinet inner region is divided into bus-bar room, handcart chamber, cable chamber by dividing plate, it is characterized in that: comprise that two L type supports are fixedly installed in respectively on the left and right side plate of bus-bar room below cabinet, also comprise two prepackage mounting rails that laterally arrange; Prepackage mounting rail two ends frame respectively are loaded on the L type support, and current transformer is lifted on the prepackage mounting rail; Be connected fixing L type support (as shown in Figure 2) with the AC metal closed switch cabinet housing
During practical implementation, carry out the current transformer prepackage earlier, current transformer is fixed on the prepackage mounting rail with screw; As shown in Figure 1; Adopt the method for riveted joint to be assemblied on the left and right side plate of switch cubicle on L type support shown in Figure 2 again, the current transformer and the prepackage mounting rail that utilize special tooling that current transformer is installed to have pre-installed then rise on the L type support, and transfer to the relevant position as required; With bolt locking, promptly accomplish whole current transformer installation process at last.The current transformer assembling of installation is as shown in Figure 4, can be found out by figure, and current transformer below cable bond row is in no occlusion state fully, and increases L type support, and current transformer is pre-installed, and current transformer is installed become convenient and swift.
It is limited that the utility model has solved the switch cubicle space, and the problem that cable is installed is blocked, is unfavorable for to the cable bond row that cabinet inner structure complicacy causes by current transformer; Simultaneously also solve the personal security hidden danger that exists in the current transformer installation process, improved operating efficiency; And having avoided current transformer when maintenance, the maintainer need open the power cut problem that bus-bar room brings.
