Embodiment Construction

[0017] like figure 1 A transformer mounting base for a low-voltage circuit breaker is shown, including a mounting base 1, which is different in that: the bottom of the mounting base 1 used in the present invention is connected with a copper bar 2, and the upper end of the mounting base 1 is two The side is provided with fastening components. At the same time, in order to facilitate the connection of the subsequent transformer device 10 and ensure that there will be no looseness after installation and will not affect the use effect, the upper end of the installation base 1 is provided with a transformer installation joint 3 . Moreover, in order to ensure the stability of the connection of the copper bar 2 and prevent it from sliding easily, a positioning component is provided at the bottom of the installation base 1 , where the positioning component connects with the copper bar 2 .

[0018] As far as a preferred embodiment of the present invention is concerned, in order to imp...

Abstract

The invention relates to an installation substrate of mutual inductors for low-voltage circuit breakers. The installation substrate comprises an installation substrate body, and is characterized in that a copper row is connected with the bottom of the installation substrate body, and fastening assemblies are arranged on the two sides of the upper end of the installation substrate body. Meanwhile, a mutual inductor installation connector is arranged at the upper end of the installation substrate body, and a locating assembly is arranged at the bottom of the installation substrate body and connected with the copper row. The installation substrate can be used for installation locating of the mutual inductors for the low-voltage circuit breakers of various types. Due to a knurling groove, effective sliding prevention can be achieved, and combination stability is ensured. In addition, due to mutual matching of the fastening assemblies and locating assemblies, the copper row is effectively prevented from loosening after being installed. The more important is that the installation substrate can adapt to installation locating of copper rows of different types and different thicknesses.

Description

technical field [0001] The invention relates to a mounting base, in particular to a transformer mounting base for a low-voltage circuit breaker. Background technique [0002] When installing low-voltage circuit breaker transformers, due to the difference in the rated operating current of the main circuit and the structure of the power distribution cabinet, the thickness and width of the copper bars used in the main circuit are also different. The transformer housing installed on the copper bar needs to be changed according to the size of the copper bar. In this way, the traditional installation base cannot meet the needs of fixing various types of copper bars, and each type of copper bar needs to be produced separately, which increases the manufacturing cost. Furthermore, there are defects in the existing base structure, the positioning of the copper bars is not very precise, and loosening is prone to occur. Contents of the invention [0003] The object of the present in...
