Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rigid suspension power supply system for rail transit, and specifically relates to a busbar structure. Background Technology
[0002] In rigid suspension power supply systems for rail transit, busbars are used to hold the contact wire and carry current. They are connected and suspended by intermediate joints and support devices to form a rigid contact network power supply system. Due to the relatively harsh environment inside tunnels, especially in special sections such as coastal areas, rivers, and lakes, there may be water seepage or even leakage. The humidity is high, and condensation easily forms inside the busbars. Over time, the condensation accumulates and flows along the side walls to the gap between the busbar clamps and the contact wire, causing an electrochemical reaction. Long-term accumulation can cause corrosion at the contact points, and in severe cases, it can cause the contact wire to detach, affecting the quality of current collection by the pantograph and catenary. Utility Model Content
[0003] This invention provides a busbar structure to overcome the shortcomings of the prior art.
[0004] The technical solution adopted by this utility model is: a busbar structure, including a busbar body, wherein inverted V-shaped ribs are symmetrically arranged on both sides above the jaws in the cavity of the busbar body along the line direction, and the inverted V-shaped ribs are close to the jaws; a plurality of drainage holes are provided on both sides of the jaws in the line direction of the busbar body, and the drainage holes penetrate the inclined surface of the inverted V-shaped ribs away from the jaws.
[0005] Two inverted V-shaped ribs are provided, including a first rib and a second rib, and a first groove is formed between the first rib and the second rib. The drainage hole passes through the first groove and the second rib.
[0006] The inverted V-shaped ribs are provided in three forms, including a first rib, a second rib, and a third rib, and a first groove is formed between the first rib and the second rib, and a second groove is formed between the second rib and the third rib. The drainage hole passes through the first groove and the second rib.
[0007] Two convex ribs are symmetrically arranged on the inclined surfaces of the jaws outside the cavity of the busbar body, in the direction of the line. The convex ribs are located between the drain hole and the jaws and are close to the outer port of the drain hole.
[0008] Two positioning grooves are symmetrically arranged on the inclined surfaces on both sides of the jaw outside the cavity of the busbar body, in the direction of the line. The axis of the positioning grooves coincides with the center of the drain hole.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. This utility model provides inverted V-shaped ribs and drainage holes on both sides above the jaws inside the manifold drain cavity. The inverted V-shaped ribs act as a water-blocking mechanism, allowing condensate inside the manifold drain cavity to flow out through the drainage holes, thus preventing water accumulation inside the manifold drain cavity from flowing into the jaws and causing corrosion of the jaws.
[0011] 2. This utility model provides a groove at the outer port of the drain hole to prevent water from flowing along the outer slope of the manifold to the contact area between the jaws and the contact line, thus preventing jaw corrosion.
[0012] 3. This utility model improves the processing efficiency of drainage holes by setting a drainage hole positioning groove on the outside of the manifold and using this positioning groove to achieve precise processing of the drainage holes. Attached Figure Description
