Abstract

The invention relates to a method for obliquely inserting and mounting a high-voltage bushing once through an intelligent protractor. The method comprises the following steps of installing an 'intelligent tool kit' software on an intelligent cellphone, clicking an 'angle' option, enabling the long edge of the intelligent cellphone to be parallelly leaned to and attached to an oblique flange face (2a) of an interface of high-voltage equipment (2), wherein the protractor is displayed in a cellphone window of the intelligent cellphone, and then recording the oblique angle of the flange face; then slinging the high-voltage bushing in the air, and regulating the oblique state of the high-voltage bushing, wherein an oil chamber end at the upper part of the high-voltage bushing is in a high position and the tail end (10) of the high-voltage bushing is in a low position; enabling the long edge of the intelligent cellphone to be parallelly leaned to and attached to a flange face (1b) of the interface of the dangling high-voltage bushing, continuing regulating the oblique degree of the high-voltage bushing until the oblique angle of the flange face of the interface of the high-voltage bushing showed by the protractor is consistent with the oblique angle of the flange face of the interface of the high-voltage equipment, and obliquely inserting the tail end of the high-voltage bushing into the interface of the high-voltage equipment so that the mounting is completed. The method disclosed by the invention is time-saving and labor-saving. According to the method disclosed by the invention, personal security risks and equipment security risks in obliquely inserting and mounting the high-voltage bushing can be reduced, and high-voltage bushing obliquely inserting and mounting the high-voltage bushing can be completed once.

Description

technical field

[0001] The invention relates to the technical field of installing high-voltage bushings on electric power construction sites. Background technique

[0002] For transformers, converters, GIS (HGIS) and other high-voltage equipment, in order to ensure sufficient electrical safety distance and reduce equipment manufacturing costs, the external high-voltage bushings are usually inserted obliquely into the flange surface of the high-voltage equipment interface and then fixed. . The high-voltage bushing varies according to the voltage level, the length can reach more than 5-10 meters, and the weight can reach 1.5-4 tons. The current construction process is as follows: 1. Lift the high-voltage bushing that has been roughly adjusted on the ground to the side of the flange of the high-voltage equipment interface for repeated visual comparisons, and then repeatedly adjust the manual hoist to make the flange surface at the lower end of the high-voltage bushing consiste...

Embodiment Construction

[0015] Such as figure 1 As shown, the method of the present invention to complete the oblique insertion and installation of high-voltage bushings at one time by means of an intelligent protractor is to adjust the angle of the suspended high-voltage bushing 1, and then obliquely insert the tail end into the inclined high-voltage equipment 2 interface. The specific operation method is as follows :

[0016] 1) Install the "Smart Toolbox" software on the smartphone;

[0017] 2) Open the "Smart Toolbox" software on the smartphone, and click the "Angle" option;

[0018] 3) Put the long side of the smart phone 7 with the protractor displayed on the mobile phone window parallel to the inclined flange surface 2a of the interface of the high-voltage equipment 2, and record the value of the inclination angle of the flange surface;

[0019] 4) The high-voltage bushing is hoisted in the air with a lifting device combined with the main sling 3, upper auxiliary sling 4a, lower auxiliary sl...
