Background technology
Coal is the main body energy of China, and the speed of development of accelerating the reform of coal industry is at present set up a plurality of large-scale coal bases by the mode of merging and reorganization, and Coal Production scale, technical equipment modernization will become the development trend in colliery.This is once rare opportunities and challenges for middle miniaturization low voltage switchgear under most of enterprises research and development coal mine.
The space is limited under the coal mine, environment is abominable, and the various performances of down-hole low-voltage distribution apparatus are all had relatively high expectations.Domestic low voltage switchgear technology commonly used is quite ripe at present, but the ubiquity volume is bigger, and framework takes up room greatly, effectively utilize insufficient space, and the chamber space is limited, and it is little that turnover line cable is installed space, installs inconvenient especially; Because the down-hole is relatively moister, require the degree of protection height simultaneously, low voltage product does not reach requirement basically at present; Isolation method is simple, and security performance is low.Therefore, current a kind of miniaturization of research and development, high-protection level, the modularization low voltage switchgear that isolation method is good, safe and reliable of needing, to satisfy the demand of modernized large-scale mine, down-hole central authorities transformer room's improvement project especially.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of miniaturization mining low-voltage complete switch equipment, this device space is arranged compact, can effectively reduce switch cubicle and take empty usefulness, leave and take enough turnover space of lines, making things convenient for and realize the cabinet miniaturization on the basis of terminal block.
The utility model is by the following technical solutions:
The mining low-voltage complete switch equipment of a kind of miniaturization comprises that by cross section be the cabinet body frame that the section bar of L shaped semi-surrounding structure is formed by connecting, and described section bar modularization is provided with installing hole; Described cabinet body frame is by dismountable upper and lower bottom plate, side plate and the door-plate that is installed with as the cabinet wall of installing hole.
Further, described section bar is put together by upper hem, back flanging, lower hem, preceding flanging, side upper hem and side lower hem.
Further, described lower shoe modularization is provided with louvre.
Further, described modulus is 20mm.
Further, the corresponding sides of described continuous section bar connect by trip bolt.
Further, described framework is provided with one or more separate compartments.
Further, described compartment is detachably installed lower shoe, side plate and door-plate.
Further, described compartment comprises functional unit chamber, bus-bar room, cable vault.
Further, described bus-bar room is arranged on framework upper.
Further, the horizontal bus rated current of described bus-bar room is 630～6300A.
The utlity model has following advantage:
1) the utility model compact conformation, can utilize the space big: because the framework volume is little, it is little to take up room, save the space, can utilize the space significantly to improve, meet the development trend of energy-conserving and environment-protective, especially down-hole central authorities transformer room's improvement project, because the chamber of controller switching equipment is fixing under the mounting shaft, wish to use most the switchgear of miniaturization; In convenient the installation, various elements are installed compact simultaneously, make things convenient for cable turnover wiring, the conserve space of limit greatly.
2) the utility model is provided with the separate compartment of each functional compartments, and described compartment comprises functional unit chamber, bus-bar room, cable vault etc.The sidewall of each compartment and upper and lower bottom plate are detachable the installation, not only make product with compact structure, practical to have solved safe insulation problems such as the electric crack spacing that smaller volume causes, creepage distance simultaneously.Installation, operation and maintenance all can carry out before cabinet, can realize installing by wall, save erection space.
3) the utility model employing cross section is L shaped section bar, and two section bars that interconnect have interconnective fillet, and corresponding modularization is provided with installing hole on it, only need securing member to connect, easy to connect, without any connecting gusset, cost is low, and is simple and practical.So, amount of parts is controlled to a great extent, assemble simple and convenient, the intensity height, framework is empty little with taking, pass through standardized designs simultaneously, select the components and parts of high-quality for use, the spatial placement compactness can effectively reduce switch cubicle and take empty using, leaving and taking enough turnover space of lines, making things convenient for and realize the cabinet miniaturization on the basis of terminal block.In addition, because the semi-surrounding structure of L-shaped section, the space that self surrounds also can make full use of, and increases usage space.
4) adopted advanced theory of modular design on the utility model structural design, with 20mm is that base module designs, the space is conveniently cut apart and framework intensification design in the cabinet, can realize that cabinet expands arbitrarily, assemble flexible, support back outlet and side outlet method, can satisfy the different requirements of user the cabinet size.
5) horizontal bus rated current scope 630～6300A of the present utility model; To satisfy the requirement of user to different current systems.
6) the utility model is optional uses colory electrical accessory: complete, various connection annex, support the actual needs of circuit arrangement and engineering specifications flexibly interchangeably, and guarantee Electrical Safety.
