Abstract

The invention relates to a push-and-pull module guide rail and a module assembly. The module guide rail comprises a guide rail body and universal balls arranged at intervals along the length direction of the guider rail body, and a wiring passage is formed on the guide rail body and used for installing an equipotential line for electrical connection with adjacent universal balls. By the module guide rail, suspension potential caused by poor contact of individual universal ball and a module is avoided, and the reliability of a product during running is enhanced. Furthermore, the module is fixed by using a module fixing bolt at the front part of the module guide rail after the module is pushed into the module guide rail, the module is limited by using a module baffle plate at the rear part of the module guide rail, the module fixing bolt and the baffle plate are both in direct contact with a metal framework of the module, therefore, the problem of suspension potential brought by the module fixing bolt and the baffle plate is avoided. Furthermore, the guide rail is fixedly connected onto a base by using a nylon bolt in a groove on the module guide rail, so that the problem of suspension potential brought by the metal bolt is avoided.

Description

technical field

[0001] The invention relates to the field of module installation, in particular to a push-pull module guide rail and a module assembly. Background technique

[0002] High-power power electronic rectification and inverter devices such as flexible direct current transmission and STATCOM based on multi-modularity play an important role in more and more fields. Floating potential problems caused by using too much metal. Chinese patent document CN203105026U discloses a guide rail device for a DC module, which includes a base that is a base, a guide rail, a universal ball that is a universal ball and a limit block. The ball of the universal ball is in rolling contact, and the two sides of the bottom surface of the module extend downwards and are stuck on the guide rail, and the two ends of the guide rail are respectively provided with limit blocks. This guide rail device changes the sliding friction into rolling friction through the universal ball , so that the ...
