Embodiment 1

[0023] A low-voltage power distribution cabinet bus integrated assembly, including a plurality of integrated bus integrated unit components, such as figure 1 As shown, each busbar integrated unit assembly includes a substrate 1, and the left and right sides of the front of the substrate 1 have two left and right raised sides 9, and a plurality of interphase insulation parallel to the raised sides 9 are arranged between the two raised sides 9. Strip 2, raised edge and interphase insulating strip 2 can be a solid strip raised from the front of the substrate, or a frame-shaped structure raised from the front of the substrate 1. In this embodiment, the raised edge 9 and the interphase insulating The bar 2 is a raised frame structure, the inside of the frame structure is hollow, and a reinforcing rib 11 is arranged in the middle. An accommodating groove 3 is formed between the interphase insulating strip 2 and the raised edge 9 and between adjacent interphase insulating strips 2, a...

Abstract

The invention provides a bus integrated assembly for a low-voltage power distribution cabinet. The bus integrated assembly comprises multiple bus integrated unit assemblies which are integrated together, wherein each bus integrated unit assembly comprises a substrate; a left convex edge and a right convex edge are arranged on the left and right sides of the front surface of the substrate; multiple alternate insulating strips parallel to the convex edges are arranged between the two convex edges; accommodating grooves are formed between the alternate insulating strips and the convex edges, and between adjacent alternate insulating strips; branch bars are arranged in the accommodating grooves; the lower ends of the branch bars extend out of the substrate for a fixed distance to form wiring ends; for main busbars perpendicular to the branch bars are arranged on the back surface of the substrate; the four main busbars are mutually isolated through insulating lug bosses; the upper ends of the branch bars are connected with the corresponding main busbars through fixed bolts; and an expansion connecting mechanism is arranged on the two convex edges. According to the bus integrated assembly, a branch bus and a circuit breaker are connected by screws, and a connecting point is visible; and the bus has no any exposure point, so that the bus integrated assembly is extremely high in safety and can be optionally combined into a unit.

Description

technical field [0001] The invention relates to a low-voltage electrical component, in particular to a low-voltage power distribution cabinet assembly. Background technique [0002] In the prior art, the switches of busbars and circuit breakers in the medium and low voltage power distribution cabinets are installed in a superimposed manner, which makes it difficult to dissipate heat. The circuit breaker is easy to burn out if the temperature is too high, and the reliability is not high. After a period of use, it is easy to burn out and open the circuit The device, the mounting screws are not visible, and the product cannot be inspected. Contents of the invention [0003] In order to solve the problems existing in the background technology, the present invention provides a low-voltage power distribution cabinet bus integrated assembly, the branch bus of the bus integrated assembly and the circuit breaker are connected by screws, the connection points are visible, and the ti...
