Description
Technical field
Present invention relates particularly to a kind of electric power O&M power tool more particularly to a kind of auxiliary dresses for ground wire assembly and disassembly
It sets.
Background technique
China's economic reality goes out swift and violent growth momentum in recent years, and social production has more need for power supply
It asks, therefore power grid construction just constantly puts to good use and comes, the design of earthed system can effectively ensure the normal operation of electric system,
It is more ensured for people's life safety belt, avoids the generation of electric power accident.Growth of the national economy to electricity needs,
In the higher and higher daily life for appearing in us of 220kv and the above substation, 220kv becomes primary power distribution voltage etc.
Grade, so that more and more people start to pay attention to quality of life, Electrical Safety has caused public caused greatly for social development
It is many note that power plant, System in Substation refer to the metallic ground body being embedded in soil and by these metallic ground body phases
The main purpose of the general name of network structure made of connecting, electric system ground connection is exactly to utilize grounding body short circuit current and thunder
Electric current introduces deep soil with most fast speed.
It is the basic measures for guaranteeing service personnel's personal safety, the dress of ground line that ground wire is installed on the transformation device of maintenance
If quality is directly related to the protection level to service personnel.However at station scene, it often can be appreciated that some installings
Nonstandard ground line, operations staff also often complain that the difficulty encountered when installing ground line, some equipment can not install ground connection
Line, some places are difficult to install ground line, or even the personal injury of electric shock also occurred during installing ground line.
The position of some installing ground lines is excessively high, and operations staff is difficult to install, sometimes it cannot be guaranteed that people and being grounded conductor
Between distance meet the requirement of safe distance, the place of some installing ground lines is too close at a distance from surrounding energized conductor, Bu Nengbao
The safe distance of witness and energized conductor, therefore the device of substation's installing ground line is transformed, is renovated, it is allowed to standardize
Change, meet safety requirements, be problem anxious to be resolved, especially after carrying out Unattended substation, Centralized Monitoring, runs people
The responsible substation equipment maintenance safety measure of member assign a task it is heavier, if the ground line installing device not standardized,
Just it is difficult to ensure safety when operations staff installs ground line, it is difficult to guarantee installed ground connection line mass, it is difficult to ensure maintenance
The safety of personnel.
All the time, 220kV and the ground line assembly and disassembly work of the above outside transformer substation are all that degree of risk is very high, time-consuming very long
One work.Such as 220kV switch maintenance needs to use 30 jin or so of ground wire during switching two sides installing ground wire
4.5 meters of long brake pull-rods are provoked, and are attached on nearly 6 meters of high frameworks, whole process firmly range according to operator not
It is also different with exerting oneself, probably between 67.5kg-210kg.The upper limb of one adult is averaged load-bearing range in 30kg-60kg,
By data comparison it can be found that assembly and disassembly ground line has quite high force requirements for operator.And in the mistake provoked
Cheng Zhonghui shakes, it is most likely that touches charging equipment.When operator expends a large amount of during assembling and disassembling ground line
Between, seriously affect the job schedule and working efficiency of operation maintenance personnel.As it can be seen that there is labour by force in the assembly and disassembly operations being grounded at present
Degree is big, has a certain security risk, low efficiency, the qualification of operation by staff's operating experience, physical condition, the age,
Subjective will is affected.
