Problems solved by technology

However, a lot of power supply is often lost, which affects the electricity fee income of power supply companies.
At present, the society has higher and higher requirements on the reliability of power supply, and power companies are also striving to improve their service image. The current situation that there will be a power outage every time the switch blade on the closed pole is replaced is no longer suitable for the requirements of the situation.

Embodiment Construction

[0014] The load replacement method of the switch knife on the closed rod of the present invention comprises the following steps:

[0015] First measure the current of the three-phase conductor 1 phase by phase with a clamp-type ammeter, and the current of each phase does not exceed 200 amperes. There are three fixing devices for supporting and fixing the drain wires, and the drain wires are installed phase by phase on both sides of the knife on the closed rod of the same-phase wire, and the drain wires 2 are placed in the fixing devices on the insulating cross arm 3, forming a temporary passage ;

[0016] Add an insulating plate to the pile head of the switch knife on the closed pole and disassemble the lead wires on both sides of the knife knife on the closed pole, fix them on the same phase wire, add insulation and shielding measures, and then remove the fixed screw of the gate knife on the closed pole, and put the special Connect the sling to the switch knife on the pole a...

Abstract

The invention relates to an on-load change method of a knife switch on a 10kV closing rod. The method comprises the following steps of: mounting a current steering device and changing a knife switch on a closing rod. The method has clear steps, easy operation, appropriate insulation and isolation measures in the operation process and high safety factor, thereby solving the problem of changing theknife switch on the closing rod by powering down, better adapting to the line reconstructions of urban power grids and ring power grids, better meeting the running requirement on uninterrupted power supply of ring power supply networks and greatly improving the power supply reliability. The method has great practical values on enlarging the live working field and improving the power supply reliability at the present with the distribution line technology advanced and developed day by day.

Description

technical field [0001] The invention relates to a live working method of a power distribution line, in particular to a method for on-load replacement of a switch knife on a 10kV closed pole. Background technique [0002] In order to adapt to the flexibility of the dispatching method and reduce the scope of power outages, pole-mounted switches are widely used on 10kV distribution lines. Due to reasons such as long service time, faults of the switch blades on the pole, maintenance of the pole blades on the line, etc., it is necessary to replace many closed gate blades on the pole in operation. [0003] The replacement of the upper switch knife on the closed rod generally adopts a power outage operation, and the method is simple and easy. However, a lot of power supply is often lost, which affects the electricity fee income of power supply companies. At present, the society has higher and higher requirements on the reliability of power supply, and electric power companies are...
