Abstract
The utility model provides a circuit breaker installing structure comprising a screen cabinet framework, and multiple U-shaped plates which are connected onto the screen cabinet framework. Multiple circuit breaker installing guide rails are fixedly connected onto the U-shaped plates respectively. Circuit breakers are fixedly connected with the circuit breaker installing guide rails, and operation surfaces of all the circuit breakers are arranged on the same plane. The screen cabinet framework, the U-shaped plates, the circuit breaker installing guide rails and the circuit breakers are connected with each other by using fasteners. The circuit breaker installing structure has characteristics of being convenient to detach and replace and suitable for installing requirements of the circuit breakers with different model numbers and outline dimensions.
Description
Technical field
The utility model relates to rail traffic vehicles manufacturing technology field, is specifically related to a kind of structure for mounting circuit breaker, is applicable to the installation of locomotive electric cad system screen cabinet breaker.
Background technology
In the alternating current electric locomotive that research and development are manufactured at present, as DJ type, DJJ1 type, DJJ2 type, and advanced HXD1 type, HXD1B type, HXD1D etc., the circuit breaker that locomotive uses (single-stage circuit breaker, double-pole cut-out, three grades of circuit breakers etc.) substantially Shi Youyijia supplier provides.Generally, the height of different manufacturers circuit breaker is different, and the circuit breaker height dimension of identical producer different series is also different.And in locomotive screen cabinet design and using, in order to prevent that crew from getting an electric shock and facilitating crew to operate, the operating surface of circuit breaker is in same plane, so circuit breaker is general, adopt following structure to install:
As shown in Figure 1, existing mounting structure be according to height by a Plate Welding that plays padded effect shielding on cabinet skeleton, then circuit breaker guide rails is arranged on steel plate, finally circuit breaker is fixed on circuit breaker mounting guide rail.Circuit breaker to different model size, selects the steel plate of different-thickness padded, to realize, rear all breaker operator faces is installed at grade.But adopt this mounting structure to have significant limitation, show:
(1) for the research and development of new product, generally need to select Liang Jia supplier, if adopt current mounting means, for the circuit breaker of different model, the screen cabinet skeleton structure that circuit breaker is installed that only changes just can meet the demands, and has increased design and labour cost.Meanwhile, adopt the padded mode of steel plate, waste of material is serious.
(2) circuit breaker in the existing screen cabinet using in section, if there is the circuit breaker stopping production of certain model, in the situation that other electric parameter can meet the demands, can whether the overall dimension of circuit breaker meets the demands be changed decision.If adopt the method for welding to install, greatly reduce the possibility of this general replacing.
For the flexibility that adapts to market demand and improve product application, consider on locomotive, conveniently to adjust and to install the circuit breaker of different model, overall dimension, design can be suitable for the mounting structure of different overall dimension circuit breakers.
Utility model content
For overcoming above-mentioned technical problem, the utility model provides the mounting structure of a kind of applicable different model, different overall dimension circuit breakers.
A kind of structure for mounting circuit breaker, comprise screen cabinet skeleton, and be connected to a plurality of U-shaped plate on screen cabinet skeleton, a plurality of circuit breaker mounting guide rails are fixedly connected on respectively on U-shaped plate, circuit breaker is fixedly connected with circuit breaker mounting guide rail, and each breaker operator face is in same plane.Between screen cabinet skeleton, U-shaped plate, circuit breaker mounting guide rail and circuit breaker, all with securing member, connect.
In technique scheme, be connected to U-shaped buttress on screen cabinet skeleton according to the size of circuit breaker size, adopt corresponding height, the opening direction that described U-shaped plate arranges with respect to the installed surface on screen cabinet skeleton toward indent or toward evagination, with the operating surface of all circuit breakers after guaranteeing to install at grade.
In order to simplify screen cabinet and difficulty of processing, a kind of preferred technical scheme is: all screen cabinet skeletons at grade, are installed on same plane the U-shaped plate of differing heights.
Remarkable result of the present utility model is:
1. when the circuit breaker of different model size is installed, can select easily the U-shaped plate of corresponding height and be assemblied on screen cabinet skeleton with circuit breaker is supporting, guaranteed the operating surface of the circuit breaker after installing at grade, the installation requirements that adapted to the circuit breaker of different model, overall dimension, have improved the flexibility of product application.
2. when needs are changed different model circuit breaker, only need loosening fasteners, change the U-shaped plate of corresponding height, be assembled to the installed surface on screen cabinet skeleton, dismounting and change is very convenient.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of prior art.
Fig. 2 is mounting structure schematic diagram of the present utility model.
Wherein, 1-steel plate, 2-screen cabinet skeleton, 3-circuit breaker, 4-circuit breaker mounting guide rail, 5-U template.
Embodiment
As shown in Figure 2, a kind of structure for mounting circuit breaker, comprises screen cabinet skeleton 2, and 5, three the circuit breaker mounting guide rails 4 of three U-shaped plates that are connected on screen cabinet skeleton are fixedly connected on U-shaped plate 5, and circuit breaker 3 is fixedly connected with circuit breaker mounting guide rail 4.Between screen cabinet skeleton 2, U-shaped plate 5, circuit breaker mounting guide rail 4 and circuit breaker 3, all with securing member, connect.After installing, all breaker operator faces are in same plane.
For simplifying screen cabinet and difficulty of processing, all screen cabinet skeletons 2 at grade, are installed on same plane the U-shaped plate 5 of differing heights.
According to the size of circuit breaker size, adopt the U-shaped plate 5 of corresponding height.For example, for the circuit breaker of the size maximum of the top, select highly maximum U-shaped plate, the opening direction that U-shaped plate 5 arranges with respect to the installed surface on screen cabinet skeleton 2 toward indent; For the circuit breaker of below size minimum, select highly minimum U-shaped plate, the opening direction that U-shaped plate 5 arranges is contrary with the opening direction of other U-shaped plate, with respect to shielding installed surface on cabinet skeleton 2 toward evagination; After installing with assurance, the operating surface of all circuit breakers at grade.
It is convenient that the structure for mounting circuit breaker that the utility model provides has dismounting and change, can adapt to the feature of the circuit breaker installation requirements of different model, overall dimension.
Claims (5)
1. a structure for mounting circuit breaker, it is characterized in that: comprise screen cabinet skeleton, and be connected to a plurality of U-shaped plate on screen cabinet skeleton, a plurality of circuit breaker mounting guide rails are fixedly connected on respectively on U-shaped plate, circuit breaker is fixedly connected with circuit breaker mounting guide rail, and each breaker operator face is in same plane.
