3、ahren Teil 501: Spannungsfestigkeit This “Aerospace Series“ Prestandard has been drawn up under the responsibility of ASD-STAN (The AeroSpace and Defence Industries Association of Europe - Standardization). It is published for the needs of the European Aerospace Industry. It has been technically app
4、roved by the experts of the concerned Domain following member comments. Subsequent to the publication of this Prestandard, the technical content shall not be changed to an extent that interchangeability is affected, physically or functionally, without re-identification of the standard. After examina
5、tion and review by users and formal agreement of ASD-STAN, it will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) for formal vote and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national le

10、059-100, Aerospace series Electrical cables, installation Protection sleeves Test methods Part 100: General. 3 Dielectric test 3.1 Equipment The dielectric equipment is composed of an electrical generator and a test fixture. The test fixture is composed of a structure containing several rows of meta
11、llic ball chains and a metallic mandrel. The negative pole of the electrical generator is connected to the metallic mandrel with a clip. The positive pole is connected to the metallic ball chains and the metallic frame. See a type of equipment in Annex A (informative). 3.2 Preparation of specimens T
12、he specimen and the metallic mandrel are 50 cm long. The external diameter of the metallic mandrel shall be as closed as possible to the internal diameter of the protection sleeve to test. The specimen is installed on the metallic mandrel which is connected to the negative pole of the generator. The
13、 assembly is installed into the chamber so that the ball chains are only in contact with the specimen and not with the mandrel. The not protected part of the metallic mandrel which allows the connection must be kept out of the chamber. 3.3 Test procedure The protection sleeve shall be subject to a v
14、oltage test at ambient temperature. The voltage specified by the technical specification with a frequency of 40 Hz to 60 Hz, shall be applied for at least 1 minute between the metallic ball chains and the mandrel. The voltage rise time shall be between 300 V per second and 500 V per second. After on
15、e minute at the value defined in the product standard, the test should be stopped. 3.4 Requirement There shall be no electrical perforation of the sleeve and no evidence of damage. prEN 6059-501:2009 4 Annex A (informative) Schematic drawing of the dielectric equipment Key 1 Specimen under test: 400 mm 2 Metallic mandrel 3 Metallic ball chains 4 Test fixture 5 Sleeve protection 6 Electrical Generator 7 Value kV 1 6 7 5 4 3 2
