Abstract

The invention discloses a connection method of high voltage cable on an electromotive, comprising the following steps: 1. providing a high voltage cable (A) which comprises a conductor (11), a conductor semi-conductive layer (12), an insulation layer (13), an insulation semi-conductive layer (14), a metal external shielding layer (15) and an external jacket (16) in sequence from interior to exterior, with one end being sleeve connection end (A1) and the other end being transformer connection end (A2); 2. sealing and connecting the sleeve connection end (A1) of the high voltage cable into a through-the-wall high voltage sleeve tube (2) in an inner connection mode; and 3. connecting the transformer connection end (A2) of the high voltage cable into a high voltage connector (3) in an inner connection mode. Therefore, the invention is high in safety, and avoids the risk of electric shock occurrence by adopting sealed inner connection mode.

Description

technical field [0001] The invention relates to a connection method, in particular to a connection method for high-voltage cables on electric locomotives. Background technique [0002] High-voltage cables A for electric locomotives, such as figure 1 As shown, it generally includes conductor 11, conductor semiconducting layer (also known as conductor shielding layer) 12, insulating layer 13, insulating semiconducting layer (also known as insulating shielding layer) 14, metal Outer shielding layer 15 and outer sheath 16 . The main function of the high-voltage cable is to penetrate the 25KV power supply of the grid into the electric locomotive. Therefore, the quality of the high-voltage cable connection is one of the important reasons that determine whether the electric locomotive can operate normally. [0003] At present, the 25kV voltage through the wall in the electric locomotive is connected to the locomotive by using a high-voltage current transformer M, such as figure...
