Description

A portable high-altitude maintenance platform

technical field

The invention belongs to the technical field of substation maintenance and climbing equipment, and relates to a portable high-altitude maintenance platform.

Background technique

There are usually two ways to install current transformers, voltage transformers, line YDRs, disconnectors, and lightning arresters of 35kV and above in substations.

The first method is to use a large crane for installation. Due to the large size of the crane, the crane cannot enter and complete the installation due to space restrictions, traffic road restrictions and many other factors in some sites; the cost of using the crane is high; you need to rent the crane in advance before installation The party needs to make an appointment and wait, and professional crane personnel are required to operate. The work is limited by the crane rental party, so a lot of time and financial resources were wasted during the entire equipment installation process, and it has not been widely used (such as the county bureau is not equipped).

The second way is to use the manual method, which is mostly used when the space of the site is limited. However, the physical load of the manual method is too heavy, especially the site cannot provide the safety guarantee conditions under the strong physical labor of the personnel, and the personnel are very unsafe.

For example: when the isolating switch is maintained in substation, since the base of the switch knife is located directly under the porcelain vase; therefore, the porcelain vase must be hoisted before maintenance and other operations can be performed. It is almost impossible to manually dismantle the existing porcelain bottles at present, and it is extremely dangerous and labor-intensive to operators. Also there is very big deficiency in the crane hoisting method commonly used in addition. First of all, according to the safety distance requirements, the lines around the isolation switch must be powered off to ensure an effective safety distance, which not only increases operational risks, but also causes power outages on redundant lines. Secondly, the crane is affected by the field equipment and facilities, and it is difficult to target all the porcelain bottles on the same disconnector at the same position; moving back and forth and adjusting the position of the crane not only increases the maintenance time, but also increases the possibility of safety accidents.
