Description

A quick installation method for intelligent power distribution terminal cabinets on poles

technical field

The invention belongs to the field of electric power communication equipment, and in particular relates to an installation method of an intelligent power distribution terminal cabinet.

Background technique

Intelligent distribution terminal is an important part of distribution automation construction. It is mainly used in 10kV overhead lines to complete the operation detection and monitoring functions of distribution lines, and realize the control of 10kV/20kV distribution network. Real-time monitoring of primary equipment such as switches, distribution transformers, and capacitors. The installation of the traditional intelligent power distribution terminal is to weld several bolts or weld angle steel on the column installation side of the intelligent power distribution terminal cabinet and open bolt holes on the angle steel. The power distribution terminal cabinet is raised to the installation height, so that the welding bolts or bolt holes are aligned with the corresponding installation round holes of the cross arm, and then fixed by means of parallel nuts or threaded bolts. Since the intelligent power distribution terminal itself weighs more than 50kg, and it is installed on the column at a height of about 3 meters above the ground, or the construction personnel are lifted to the installation height of the intelligent power distribution terminal by a construction crane, it is necessary for the construction personnel to climb on the column and at the same time lift the intelligent distribution terminal. The power terminal cabinet is lifted to the installation height and the installation holes are aligned. At the same time, it is necessary to use nuts or bolts to mechanically connect and bolt the intelligent power distribution terminal cabinet and the cross arm. The installation process is labor-intensive, and the bolt holes are aligned with each other during the installation process. And positioning is very difficult. When the bolts are not fully tightened, the intelligent power distribution terminal cabinet is easy to tilt, resulting in excessive tightening torque of the bolts or failure to tighten them completely. Improper operation during the installation process may also easily cause the smart power distribution terminal cabinet to fall from the air and cause damage to the equipment. It is also prone to bolts falling from the air. The construction personnel must return to the ground or ask someone to pick up the bolts before installing. In addition, welding bolts on the column-mounted side of the smart power distribution terminal cabinet will easily reduce the protection level of the cabinet. For welding angle steel, you need to choose the same angle steel as the shell material of the smart power distribution terminal cabinet and increase the weight of the smart power distribution terminal cabinet itself, which increases costs.

Therefore, a new technical solution is needed to solve the above problems.

Contents of the invention

The technical problem to be solved by the disclosure of the present invention is to provide a quick-installation method for a pole-mounted intelligent power distribution terminal cabinet with a simple structure and easy installation.

In order to achieve the above object, the present invention can adopt following technical scheme:

Correspondingly, the quick installation method of the intelligent power distribution terminal cabinet above the pole is as follows:

Install the supporting bracket on the column through the hoop, and then lift the cabinet to the installation height, so that the bent part of the quick-installation hook is hung on the side wall of the upper supporting bracket. At this time, the cabinet will not fall. The upper mounting holes on the upper bearing bracket are respectively on the same vertical line as the upper embedded nuts on the quick-loading hook and the lower embedded nuts on the embedded nut parts, and the upper bearing bracket and the quick-installing hook are fixed with bolts. And fix the embedded nut part with the lower bearing bracket.

Compared with the prior art, the present invention can conveniently install the cabinet on the column, improve the installation efficiency and reduce the installation cost. The quick-installation hooks and embedded nuts are located outside the cabinet, which does not change the protection level of the cabinet, and at the same time reduces the processing time and cost of the cabinet.
