Embodiment Construction

[0019] Below with the accompanying drawings ( Figure 1-Figure 2 ) The implementation of the present invention is described.

[0020] like figure 1 As shown, a switch branch box includes a box body 1, a cable inlet and a cable outlet at the bottom of the box body 1, a switch unit 2 fixed in the box body 1, and the switch unit 2 has an incoming line switch bushing 3 and an outgoing line switch The bushing 10, the axial direction of the incoming line switch bushing 3 intersects with the axial direction of the cable inlet in a T-shape, and the axial direction of the outgoing line switch bushing 10 intersects with the axial direction of the cable outlet in a T-shape. The T-shaped cross refers to the situation of perpendicular crossing, which can also be called T-shaped. A T-shaped intersection may also refer to a substantially perpendicular situation. The purpose of saying this is to conceptually distinguish it from the situation of parallel arrangement or parallel design in th...

Abstract

The invention provides a novel switch branch box with compact structure, less electrical connecting points, simple connecting mode and high reliability. The switch branch box comprises a box body, a cable inlet and a cable outlet which are both positioned at the bottom of the box body, and a switch unit fixed in the box body, wherein the switch unit is provided with an entrance switch bushing and an exit switch bushing. The switch branch box is characterized in that the axial direction of the entrance switch bushing and the axial direction of the cable inlet are in a T-shaped cross; and the axial direction of the exit switch bushing and the axial direction of the cable outlet are in a T-shaped cross.

Description

technical field [0001] The invention relates to the cable branch technology in the electrical field, in particular to a switch branch box used in the electric power industry. Background technique [0002] Due to the rapid development of the national economy, most regions are vigorously speeding up the transformation of the power grid. Correspondingly, there is a huge demand for ring network cabinets and branch boxes for the power grid, and the requirements for their reliability are getting higher and higher. Due to the relatively high cost of the ring main unit, the ordinary high-voltage cable branch box, especially the branch box with switches, is widely used in urban power grid reconstruction because of its low cost and can replace the ring main unit in some cases. The switch unit of the existing cable branch box with switch is generally installed vertically, so the switch inlet and outlet bushings are arranged up and down, and the switch busbar and the external inlet and ...
