Telescopic insulating multifunctional power cut and transmission operating rod for power distribution network system

Abstract

The invention relates to a power distribution network system telescopic insulation multifunctional power outage and transmission operating rod which comprises a telescopic rod type insulation rod, an operation end is installed on the insulation rod and provided with a low-voltage knife switch closing operation opening, a low-voltage knife switch opening operation opening and a switch button operation portion, and the lower end of the insulation rod is provided with a storage cavity. A flashlight is installed in the storage cavity, and a low-voltage electroscope is further installed at the lower end of the insulating rod. The power cut and transmission operating rod meets the safety distance between an operator and a live part, ensures the personal safety of the operator, and effectively prevents electric shock and arc burn in the operation process.

Description

technical field [0001] The invention relates to a telescopic insulating multi-function power-stopping operation rod of a distribution network system. Background technique [0002] At present, 10kV on-pillar distribution transformers are mostly used together with distribution transformers and integrated distribution boxes. The integrated distribution boxes require switch knife switch equipment, data acquisition instruments and reactive power compensation equipment to be assembled in a closed or semi-enclosed metal cabinet. The low-voltage integrated distribution box can make or break the circuit with the help of manual manual or automatic switch during operation. [0003] The integrated distribution box has the advantages of small size, small footprint, fixed location, free from site environment restrictions, high space utilization, and easy installation. Because of its special technical performance, unique configuration functions, safe and stable operation, and It has the c...

Problems solved by technology

[0005] First, in residential areas, limited by terrain, in order to solve the load increase, it is difficult to choose a spacious geographical location to install power distribution equipment in the existing terrain

[0006] The second is to gradually carry out road and field environment reconstruction and new rural construction in rural areas. After the new equipment is put into operation, the land occupation is gradually reduced and compressed, and the geographical environment of power facilities changes. After the maintenance personnel arrive at the site, they will find that the ladders they carry are not necessarily suitable for the site. geographical environment

[0007] The third is that in the new round of rural power grid upgrading and transformation in recent years, the design drawings of the distribution network clearly stipulated the installation of the integrated distribution box in the form of hoisting, and the cross arm that originally fixed the integrated distribution box was removed. Instead, it is directly hoisted on the cross-arm of the distribution transformer. The maintenance personnel lack a safe and reliable fixed point of the ladder for on-site operations. It is inconvenient to build a ladder, and it is even more inconvenient for the power-off and power-off operation of the integrated distribution box.
