Small bus bar installed in a high-voltage cabinet modular cabinet

Abstract

The invention discloses a modular internally-installed small bus for high-voltage cabinets, comprising a high-voltage cabinet. A small bus cabinet body is fixedly arranged inside the high-voltage cabinet. A small bus fixing device is movably arranged on a slide rail. The small bus fixing device includes an upper clamp block and a lower clamp block. An upper clamp slot and a lower clamp slot are combined to form a small bus fixing slot. Heat conducting plates are arranged on the inner sides of the upper clamp slot and the lower clamp slot respectively, and the heat conducting plates are arranged in arc heat dissipation slots. A raised basket is fixedly arranged on a small bus cabinet door. A ventilation filter net is arranged in an installation slot formed in one side of the raised basket away from the small bus cabinet door. Rotating blades are fixedly arranged at one end of a rotating rod away from a motor. The modular internally-installed small bus for high-voltage cabinets providedby the invention is internally equipped with natural ventilation and motor-assisted ventilation structures which can dissipate the heat generated by the small bus. The small bus fixing device can moveand fix small buses of different thicknesses. Thus, the modular internally-installed small bus has a wider application range.

Description

technical field [0001] The invention relates to the technical field of high-voltage cabinets, in particular to a small bus bar installed in a modular cabinet of a high-voltage cabinet. Background technique [0002] In the prior art, the application number is "201720195270.1", a small busbar room on the top of a central cabinet, including brows, brow cover plates and small busbar terminals, the brow cover plate is a split structure, and the split brow cover The board is composed of two parts, the brow cover and the back support plate. One side of the brow cover is connected with one side of the back support plate through a rotary hinge, the other side of the brow cover is fixed on the brow with hexagonal bolts, and the other side of the back support plate is It is fixed on the cabinet body by hexagonal bolts. The structure of the small busbar room on the top of the central cabinet is more convenient to open the brow cover without using other pointed tools for assistance; it i...

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above-mentioned small busbar cabinet is not equipped with a heat dissipation and ventilation structure, so that the heat generated on the small busbar cannot be ventilated in time, and long-term use will easily lead to overheating of the small busbar and internal Electrical components are damaged; 2. There is no device for stably clamping small busbars of different thicknesses in the above-mentioned small busbar cabinet, which makes the small busbar wiring not clear and stable enough, easy to be fixed unstable or entangled, affecting use and maintenance; 3 , The above-mentioned small busbar cabinet lacks a device for fixing the small busbars one by one, and the threading positions of the small busbars are fixed. During the threading, the small busbars may be bent at an acute angle, and the fixing positions of the small busbars cannot be adjusted according to the actual situation. , there are certain limitations
