CN103442543A - Electromagnetic compatibility shield plate for city railway vehicle - Google Patents

Abstract

The invention discloses an electromagnetic compatibility shield plate for a city railway vehicle and belongs to the field of city railway vehicle electromagnetic shielding. The electromagnetic compatibility shield plate comprises a plurality of silicon steel plates with the thicknesses of 0.3mm. Every two silicon steel plates are fixed with glue through a hydraulic method. The electromagnetic compatibility shield plate is formed by a plurality of layers of thin silicon steel plates in a binding-pressing mode, the overall thickness and weight of the electromagnetic compatibility shield plate are only 1/4 those of an existing carbon steel electromagnetic compatibility shield plate for the city railway vehicle, the electromagnetic shielding effect equal to that of the existing carbon steel electromagnetic compatibility shield plate can be achieved, and design requirements of various high-end vehicle types can be completely met. In addition, the electromagnetic compatibility shield plate has the advantages of being simple in structure, light, practical, convenient to mount, suitable for being popularized and the like.

Description

Suburban railway vehicle compatible with the electromagnetic shield plate

FIELD

[0001] The present invention belongs to the field of electromagnetic shielding suburban railway vehicle, particularly, to a suburban railway vehicle compatible with electromagnetic shielding plate. Background technique

[0002] At present, a number of projects for metro vehicles in Japan have adopted the traction system, its magnetic flux leakage filter reactor is large, will not cause passengers with pacemakers and other medical devices in order to ensure that the more magnetic flux leakage great impact and safety hazards, generally increased EMC shielding plate to the filter reactor to electromagnetically shield the magnetic flux leakage thereof. However, conventional carbon steel requires EMC shielding plate made into a thickness of 8mm or more is preferable to achieve the shielding effect, the use of such heavy steel shield plate causes an increase in the suburban railway vehicle weight, it is difficult to satisfy high-end models Design requirements.

SUMMARY

[0003] In order to solve the conventional electromagnetic steel suburban railway vehicle employed Compatible shielding plate, which is reached over the shielding effect must be made into the form of heavy, leading to an increase of the suburban railway vehicle weight, it is difficult to meet the design requirements of high-end models technical problem, the present invention provides a vehicle suburban EMC shielding plate.

[0004] The present invention solves the technical problem adopted technical solution is as follows:

[0005] suburban railway vehicle EMC shielding plate by a plurality of silicon steel sheets of 0.3mm thickness, each of two adjacent silicon steel sheets are fixed with glue by the hydraulic method.

[0006] Advantageous effects of the present invention are: the EMC shielding plate using a multilayer thin silicon steel sheet adhesion repression, the total thickness and weight of the vehicle only suburban conventional electromagnetic steel employed Compatible shield a quarter of the thickness of the plate, was able to reach its electromagnetic shielding effect of the same level, fully meet the design requirements of various types of high-end models. In addition, the EMC shielding plate further has a simple structure, lightweight and practical, easy to install and is adapted to popularize the like.

BRIEF DESCRIPTION

[0007] FIG. 1 is a schematic structural diagram of the suburban railway vehicle according to the present invention with a perspective EMC shield plate;

[0008] FIG. 2 is a partially enlarged view of portion I 1.

Detailed ways

Drawings and embodiments of the present invention will be further described in detail [0009] below in conjunction.

[0010] FIGS. 1 and 2, the suburban railway vehicle according to the present invention by the EMC shielding plate 7 having a thickness of 0.3mm silicon steel sheet composition, the choice of materials for the silicon steel sheet: cold rolled grain oriented silicon steel (siliconsteel) , silicon steel grade: B30G140_S.

[0011] each adjacent two silicon steel plates are fixed by glue hydraulically, the total thickness of the shielding plate only EMC

2.5_. EMC test by known magnetic flux leakage, as compared with conventional steel EMC shielding plate suburban vehicles have the same electromagnetic shielding effect of the employed, the total thickness and weight of the EMC shielding plate of the present invention are merely conventional suburban Carbon electromagnetic shield vehicle employed compatible quarter of the plate thickness. Vehicle not only achieve the purpose of weight loss, but also for the next car equipment layout saves a lot of space, while saving energy for the vehicle operator. Therefore, the EMC shield plate fully meet the design requirements of various types of high-end models. [0012] Further, the present invention is compatible with the suburban railway vehicle electromagnetic shielding plate further has a simple structure, lightweight and practical, easy to install and is adapted to popularize the like.
