Description

Adjustable cable support for transformer substation

Technical Field

The utility model relates to a cable support with adjustable transformer substation uses belongs to cable installation technical field.

Background

The traditional transformer substation cable support usually adopts a metal support, the energy consumption of the metal support in the production process is large, the working procedures are multiple, the period is long, and the product quality can not be ensured. In the aspect of rust prevention and corrosion prevention, although the cable is usually treated by adopting technologies such as external paint coating or hot galvanizing, the problem of corrosion cannot be fundamentally solved, the safety of electric facilities is seriously influenced, and the fault-free service life of the cable is greatly shortened. In addition, when current in the cable flows through the metal bracket, a magnetic field can be generated, a magnetic field closed loop is formed between the angle steels of the two brackets, the temperature of the cable is greatly increased, current loss is caused, and the circulating current temperature is further increased. Especially when the cable passes through a large current, the temperature rises suddenly, and strong arc light is formed to cause the damage of the metal bracket. In order to guarantee the safety of power transmission, measures such as thickening a cable and the like are mainly adopted so far, the manufacturing cost of power transmission equipment is greatly increased, and the problem is not solved fundamentally.

The cable support is generally made into a groove shape by welding, welding defects inevitably exist, the stress and stability of the stand column can be greatly influenced when the welding process is poor, if the cable support is made into a cylindrical shape, the integral stress performance of the cable support can be greatly improved, and the common cable support generally needs to be ordered according to the depth of a cable trench because the cable trench depths and the number of cables of transformer substations in different scales are different, and the cable support prefabricated by a factory can not be directly used generally. If a telescopic cable support can be manufactured and the cross braces with different numbers can be installed according to the number of cables, a manufacturer can be used for substations of various scales by only producing the same set of cable support components, so that the telescopic cable support has great universal applicability and can also play a great role in promoting the development of assembled substations.
