Description

A cable fast connection row between high-voltage frequency converter cabinets

Technical Field

The utility model relates to the technical field of cable speed couplings, in particular to a cable speed coupling between high-voltage frequency converter cabinets.

Background technique

With the rapid development of modern power electronics technology and computer control technology, the technical revolution of electric transmission has been promoted. It has become an inevitable development trend for the future to replace DC speed regulation with AC speed regulation and analog control with computer digital control. Among them, AC motor variable frequency speed regulation is a major means of saving electric energy, improving production process, improving product quality and improving the operating environment. It is also the main research direction of technical personnel. Variable frequency speed regulation is recognized at home and abroad as the most promising speed regulation method due to its many advantages such as high efficiency, high power factor and excellent speed regulation and starting and braking performance.

At present, the wiring method for high-voltage inverters at home and abroad is basically to connect the transformer outlet with high-voltage cables, then enter the trench, and finally connect to each corresponding unit. However, since the cables are bundled together, the insulation and voltage resistance of the cables are very high, so the insulation shielding layer of the cable used in the high-voltage inverter is very thick, and the bending radius is large, which brings about the increase of production costs, and is not conducive to assembly by workers, and the installation cost is high and the appearance is not beautiful. Sometimes it is also restricted by the use environment. Each cabinet needs to be hoisted separately, so on-site wiring is required, which is not only labor-intensive but also prone to errors. Therefore, a kind of high-voltage inverter cabinet cable quick connection is used.

At the same time, the above invention is used to accurately connect one side of the cable to the cable connection plate before the product is shipped, and the other side of the cable is accurately positioned by the line card, so that it can be quickly installed after arriving at the site, etc., which effectively solves the problems of large workload and easy errors in on-site wiring of high-voltage cables; however, the following defects still exist in the implementation process:

During the implementation of the above patent document, although the structure is simple, the operation is convenient and the use cost is low, there is a problem that when two cable lugs are electrically connected by being fixed together during use, damage to one of the cable lugs will affect the other, thus reducing the practicality.
