Problems solved by technology

[0002] In the 10kV power supply line, the insulator will be defective due to lightning overvoltage, pollution flashover in heavy fog area, etc.
If the insulator is not repaired in time, it is likely to cause the failure of the 10kV power supply line in a harsh environment and cause a power outage
If the method of power outage maintenance is adopted, it will also affect the normal operation of enterprises and institutions within the power supply range of the line, and at the same time reduce the electricity sales of power supply enterprises, resulting in huge losses of social and economic benefits
[0003] However, the existing electric power maintenance method can only be repaired under the condition of power failure, and cannot perform live operation

Embodiment Construction

[0029] Such as figure 1 Shown, the method for the tension insulator of the live exchange 10kV power supply line of the present invention, exchange the tension insulator on the 10kV power supply line under electrified condition, comprises the following steps:

[0030] 1. Confirm the weather conditions;

[0031] Choose good weather to carry out live work, avoid thunder, rain, snow, and fog, the wind force is not greater than level 5, and the relative humidity of the air is not greater than 80%;

[0032] If there is a sudden change in the weather during the live working process, which may endanger the safety of the person or equipment, the work should be stopped immediately, and the normal condition of the equipment should be restored as soon as possible, or temporary safety measures should be added;

[0033] 2. Prepare;

[0034] Shake the work with insulating tools, the insulation resistance should not be lower than 700MΩ, and the electrode spacing should be 2cm;

[0035] 3. ...

Abstract

The invention discloses a method for changing tension simulators on live 10kV power supply line, which includes steps: firstly, confirming weather conditions; secondly, preparing; thirdly, changing the tension insulators on the live 10kV power supply line and includes step 1 insulation shielding, step 2 mounting insulating tightening racks and insulating tighteners, step 3 mounting backup insulating protective pull cords, and step 4 changing the tension insulators. The method can change defective tension insulators timely when the power supply line supplies power normally, guarantee safe and normal power supply of the power supply line, avoid adverse effects of power outage upon power supply enterprises and power consumers, improve power supply reliability, increase power sales, improve industrial service quality, and guarantee uninterrupted power supply for the consumers.

Description

technical field [0001] The invention relates to an electric power maintenance method, in particular to a method for replacing a tension insulator of a 10kV power supply line with electricity. Background technique [0002] In the 10kV power supply line, due to lightning overvoltage, pollution flashover in heavy fog and other reasons, insulator defects will occur. If the insulator is not repaired in time, it is very likely to cause a failure of the 10kV power supply line in a harsh environment and cause a power outage. If the method of power outage maintenance is adopted, it will also affect the normal operation of enterprises and institutions within the power supply range of the line, and at the same time reduce the electricity sales of power supply enterprises, resulting in huge social and economic losses. [0003] However, the existing electric power maintenance method can only be overhauled under the condition of power failure, and cannot carry out live operation. Conte...
