Description
Technical Field
The invention relates to an operation method for electrically disconnecting a lead by an insulating short rod bridging method in the field of electric power engineering.
Background
At present, the uninterrupted operation project is mainly based on an insulating bucket arm vehicle and an insulating glove operation method. The operation safety is mainly based on the insulation shielding measures of the operators on the electrified bodies and the grounding bodies and the maintenance of the safety distance of the electrified bodies, and the reasonable selection of the working positions of the operators is depended. The personal experience and feeling becomes the subject of security at this time. With the improvement of reliability requirements of power enterprises, a method of load cutting is used in a large amount in engineering projects to reduce the power failure range and compress the power failure time. At present, the complex hot-line work project of changing a large number of straight rods into strain rods is carried out in the load cutting process, and the project has high work intensity and high risk and is not beneficial to large-scale development.
The existing load cutting method is characterized in that a proper linear rod is segmented by utilizing the characteristics of multiple power supplies of a line, equipment needing to be overhauled is cut out from a main line, and normal power supply of other equipment on the line is not influenced. Therefore, the operation of changing the linear rod into the tension rod is required. The operation project has complicated steps and strict shielding measures, and needs a plurality of overhead vehicles and a plurality of people to cooperate and finish. The time consumption is high, and the operation risk is extremely high.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides an operation method for electrically disconnecting a lead by an insulating short-rod bridging method, which can effectively reduce the risk of electric power construction operation and improve the efficiency.
One technical scheme for achieving the above purpose is as follows: an operation method for electrically disconnecting a lead by an insulated short-rod bridging method comprises the following steps:
step 1, two operators carry an insulating short rod to enter an insulating hopper;
step 2, lifting the insulating bucket to the side lower part of the position of the target live working line;
step 3, bypassing the live lines on two sides of the live line respectively by the first operator through the short insulating rods;
step 4, the second operator performs power failure operation on the operation line;
step 5, after the second operator finishes the operation, the first operator recovers the power supply of the target live working line;
and 6, descending the insulating bucket, and returning the operating personnel to the ground.
Compared with an insulating glove operation method, the operation method for electrically disconnecting the conducting wire by the insulating short rod bridging method has the advantages that an operator does not need to directly contact with an electrified device, and personal safety of the operator is guaranteed; compared with an insulating rod operation method, the insulating short rod operation method is matched with an insulating bucket arm vehicle, so that the operation flexibility is greatly improved; because extra shielding is not needed in the operation process, and a new tool is used, the operation time is greatly shortened, particularly, an insulating short rod bridging tool is used in a complex electrified project to replace a straight rod to change into a tension rod operation project, and the operation difficulty is greatly reduced.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific examples:
the invention relates to an operation method for electrically disconnecting a lead by an insulating short rod bridging method, which comprises the following steps of:
step 1, two operators carry an insulating short rod to enter an insulating hopper;
step 2, lifting the insulating bucket to the side lower part of the position of the target live working line;
step 3, bypassing the live lines on two sides of the live line respectively by the first operator through the short insulating rods;
step 4, the second operator performs power failure operation on the operation line;
step 5, after the second operator finishes the operation, the first operator recovers the power supply of the target live working line;
and 6, descending the insulating bucket, and returning the operating personnel to the ground.
The insulating short rod is made of FRP (fiber reinforced plastic), high-voltage-resistant insulating performance is good, the insulating short rod is made of solid materials, the length of the insulating short rod meets the requirement of the minimum insulating distance of electric power operation, operating personnel are far away from a high-voltage wire, operation is convenient, weight is light, and the requirement of safety of live working is met. The operation of the charged body through the insulating short rod belongs to an indirect operation method and an intermediate potential method.
When complex work items are encountered and the electrified implementation is very dangerous, the electrified disconnection and connection wire work method adopting the insulating short rod bridging method can be combined with a small bypass work method to isolate a power failure area, so that the complex electrified work items are changed into simple power failure work items.
The invention avoids the direct contact of operators with the charged body through the insulating gloves, and realizes the change from the direct contact of the charged equipment to the safer operation mode without direct contact of the charged equipment. In the past, due to low technological level, indirect operation can only complete simple projects, and direct contact live equipment operation is the only means of complex operation, but with the development of engineering technology, the existing insulated short-rod operation tool can completely replace hands to complete complex live operation projects.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
