Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric control cabinets, for example to an internally adjustable low-voltage electric control cabinet. BACKGROUND

[0002] The description in this section is provided only for the purpose of background information related to the present disclosure and does not constitute prior art.

[0003] As a core component in the power system, the low-voltage electric control cabinet undertakes multiple functions such as power distribution, circuit control and protection. It is internally configured with a series of electrical elements such as air switches (air switches), contactors, relays, etc. The correct installation and fixation of these elements are crucial to the performance and safety of the electric control cabinet.

[0004] Traditionally, these electrical elements are usually fixed on the card rail, and the card rail is firmly installed in the electric control cabinet by permanent connecting elements such as rivets. Although this fixing method can ensure that the card rail and the electrical elements on it remain stable during long-term operation, it also brings significant problems: once the card rail and the electrical elements on it are installed, if the position of the card rail needs to be moved due to design adjustment, incorrect installation or maintenance requirements, the rivet-fixed method will make the disassembly work extremely difficult. During the installation and debugging stage of the electric control cabinet, the position of the electrical elements may need to be adjusted several times to optimize the layout or meet specific electrical requirements. The rivet-fixed card rail limits this flexibility, thereby affecting the efficiency of the entire installation process. SUMMARY

[0005] The present application provides an internally adjustable low-voltage electric control cabinet, which enables the card rail and the electrical elements (such as air switches, contactors, etc.) on it to be conveniently moved inside the electric control cabinet by adopting a sliding rail and a mounting frame sliding fit. It greatly improves the flexibility and adjustment efficiency of the electrical element layout during the installation and debugging stage, facilitates engineers to quickly optimize the layout according to actual needs, and reduces the workload of repeated installation and disassembly. During the long-term operation of the electric control cabinet, if the electrical elements need to be maintained or replaced, the card rail can be easily moved without the need to remove a large number of fixed parts, thereby quickly accessing the target elements. In addition, when a larger or different type of electrical element needs to be replaced, the card rail position can also be easily adjusted to adapt to the size and layout requirements of the new element.
