Description

Copper bar installation structure of circuit breaker incoming cabinet

technical field

The utility model relates to the technical field of power distribution devices, in particular to a copper bar installation structure of a circuit breaker inlet cabinet.

Background technique

The lower bus bar of the existing incoming line circuit breaker copper bar structure is fixed to the bus bar clamps on both sides of the cabinet, the lower branch bar is lapped on the bus bar, and the bus bar clamps on both sides support the lower bus bar and bus bar, so as to meet the requirements of the primary system. However, the amount of copper bars and auxiliary materials used in this structure increases, which greatly increases the production cost.

Utility model content

The purpose of the utility model is to provide a copper bar installation structure of a circuit breaker incoming cabinet, so as to save materials and simplify installation.

In order to achieve the above purpose, the utility model discloses a copper bar installation structure of the circuit breaker incoming cabinet, including several main bus bars, side-entry main bars, upper branch bars, bus bars, and lower end branch bars fixed on the insulators in parallel. It includes two busbar support beams, the main busbar overlaps the lower branch bar through the bus bar, the side-entry main bar overlaps the upper branch bar, and the upper branch bar is located directly above the lower branch bar, The upper branch bar is fixed in the incoming cabinet body through the first busbar support beam, and the lower branch bar is fixed on both sides of the incoming cabinet body through the second busbar supporting beam.

Wherein, the installation surface of the lower branch row faces upward, and the bus bar overlaps the installation surface of the lower branch row.

Preferably, a number of "racetrack-shaped" mounting holes are evenly distributed on the first busbar support beam and the second busbar support beam.

After adopting the above technical scheme, the utility model has the following beneficial effects:

1. The upper branch bar is fixed in the cabinet through the first bus support beam, which increases the overall stability of the copper bar.

2. A second busbar support beam is added at the lower end of the circuit breaker, and the busbar clamp on the side incoming line side is canceled. The busbar is disconnected at the position where it overlaps with the lower busbar, and the installation position of the busbar is raised. Reduce the cost of copper and auxiliary materials. the

3. The installation surface of the lower branch bar is facing upwards, and at the same time, the bus bar clamp of the bus bar is raised to the overlapping surface of the lower end branch bar, which can save the copper consumption of the side bus bar;

4. A number of "racetrack-shaped" installation holes are evenly distributed on the first busbar support beam and the second busbar support beam, which facilitates the adjustment of the position during the installation process and makes the installation easier and more flexible.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, the utility model discloses a copper bar installation structure of the circuit breaker incoming cabinet, which is arranged in the incoming cabinet and includes several copper bars and two busbar support beams fixed on the insulator 8 in parallel, In this example, there are three main busbars 1, three side-entry main bars 2, three upper branch bars 3, three bus bars 4, and three lower branch bars 5.

The main busbar 1 is overlapped with the lower branch bar 5 through the bus bar 4 , the installation surface of the lower branch bar 5 faces upward, and the bus bar 4 is overlapped on the installation surface of the lower end branch bar 5 . The side entry main row 2 overlaps the upper branch row 3 , and the upper branch row 3 is located directly above the lower branch row 5 . The upper branch bar 3 is fixed in the cabinet through the first busbar support beam 6, and the lower branch bar 5 is fixed on both sides of the power distribution cabinet body through the second busbar support beam 7. This solution can simplify installation and greatly reduce the cost of copper bars and auxiliary materials.

A number of "racetrack-shaped" mounting holes 71 are evenly distributed on the first busbar support beam 6 and the second busbar support beam 7. The "racetrack shape" is a semicircle on both sides and a rectangle in the middle. It is convenient to adjust the position during the installation process, making the installation easier and more flexible.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model.
