Description

Insulation platform for live work in distribution network in power system

technical field

The invention relates to a device for carrying out live work in a distribution network.

Background technique

Distribution network live work has become an important means of maintenance, transformation and emergency repair of distribution network line equipment, and has played a very important role in the safe and reliable operation of the power system, emergency power repairs, and improvement of economic benefits. The live work of the existing distribution network is mainly completed by the insulating bucket truck, but the insulating bucket truck cannot work under the following conditions: First, the vertical distance that the existing insulating bucket truck can extend is only 15.6 meters. When working, it needs to be separated from the pole by a certain distance. Therefore, the work on the pole with a ground height exceeding 15.6 meters will not be completed; secondly, the insulated arm truck is more affected by the terrain, such as in rural farmland and urban alley In places such as narrow lanes and uneven construction sites, vehicles are prone to inclination, limited width, and subsidence after entering the job site, which seriously affects the safety of on-site operations. Third, the insulated arm truck is affected by the distribution network line. When the distribution network line and equipment cannot meet the safety distance for non-stop operation due to design, construction and other reasons during the construction of the distribution network line, the insulated arm truck will not be able to Do your homework.

Once the above situation occurs, the vehicle cannot be in place, and the power outage operation will have to be adopted, which will reduce the efficiency of emergency repairs on the one hand, and reduce the reliability of power supply on the other hand.

Detailed ways

The specific implementation of the present invention is described below in conjunction with accompanying drawing:

The distribution network live working platform as shown in Figure 1 mainly includes three parts, which are the fixing component 1 for fixing on the pole 4, the bracket component 2 supported and connected with the fixing component 1, and the bracket component connected to the bracket component. 2 and the rotating mechanism 3 between the fixed component 1, wherein the bracket component 2 is mainly composed of a flat plate 21, a fence 22 arranged on the flat plate 21 and a support rod 23 connected between one end of the flat plate 21 and the fixed component 1, the flat plate 21 is used to provide standing support for the operator. On the one hand, the fence 22 plays a role of safety enclosure, and on the other hand, it limits the operator's activity position, that is, the space between the right side of the fence 22 and the pole 4 shown in the figure is Dangerous space, the operator cannot enter this area, in the present invention, the distance from the right side of the fence 22 to the pole 4 is greater than 0.4 meters. The support rod 23 acts as a force balance. When in use, the left side of the flat panel 21 tends to be pressed downwards, and the right side of the flat panel 21 tends to tilt upwards. A plurality of support rods 23 are connected among them to decompose the force on the left side, so that the force on the plate 21 is uniform, and the safe use of the working platform is ensured.

The fixing assembly 1 is composed of a hoop 11 that can be opened and closed, so that the installation of the fixing assembly 1 on the pole 4 can be realized.
