Problems solved by technology

Since the porcelain post insulators supporting the tubular busbars cannot withstand excessive longitudinal loads, the original method of hanging insulating ladders for live work cannot be carried out on the tubular busbars, which brings new problems to live work in substations

Embodiment

[0024] A method for equipotential operation of a tubular busbar, comprising the following steps:

[0025] Step 1. The ground potential electrician 4 sets up the insulating ladder 5 and hangs the protective rope. The ground potential electrician 4 installs the arc suppression block 6 on the magnesium-aluminum alloy tubular busbar 1 by using the insulating rod;

[0026] Step 2. After the equipotential electrician 3 puts on the shielding suit and conductive shoes, put the arc suppression rope 7 into the tool bag and put it on his back, and enter the electric field along the insulation ladder 5;

[0027] Step 3. The equipotential electrician 3 puts the arc-suppression rope 7 into the arc-suppression tackle 6, and tie one end of the arc-suppression rope 7 under the drain plate of the drainage line 2 that needs to be disconnected; then the ground potential electrician 4 cooperates to control the arc-suppression Rope 7, so that the two ends of the arc suppression rope 7 have tension;...

Abstract

The invention relates to an equipotential operation method of a tubular bus. The method comprises the following steps that 1, a ground potential electrician installs an arc extinguishing tackle on the tubular bus; 2, an equipotential electrician enters an electric field along an electrically-insulated ladder; 3, the equipotential electrician ties one end of an arc extinguishing cable to the position below a drainage plate, and the ground potential electrician cooperates to control the arc distinguishing cable; 4, the potential electrician dismount bolts from the drainage plate; 5, the equipotential electrician controls a drainage wire to swing on the ground, and the ground potential electrician cuts off the drainage wire; 6, after fixing the drainage wire which is cut off, the ground potential electrician dismount the arc extinguishing tackle and the arc distinguishing cable which are installed on the tubular bus, and drainage-wire-cutting work for the phase is ended; 7, the operation items from step 1 to step 6 are repeated till drainage-wire-cutting work tasks of three phases are completed. According to the equipotential operation method of the tubular bus, the electrician enters the electric filed through the electrically-insulated ladder for developing equipotential hot line work, the method is simple, convenient and flexible, labor intensity of operating personnel can be greatly alleviated, and power transformation hot line work is promoted to be developed generally.

Description

technical field [0001] The invention relates to the field of substation maintenance operations, in particular to a method for equipotential operation of tubular busbars. technical background [0002] In the power system, the technology of live work in the field of line and distribution network has been very mature, and the safety and stability of live work in substations have also received more and more attention. With the continuous improvement of the system's requirements for power supply reliability, the tubular busbar gradually replaces the original wire busbar. Since the porcelain post insulators supporting the tubular busbar cannot withstand excessive longitudinal loads, the original method of hanging insulating ladders for live work cannot be carried out on the tubular busbar, which brings new problems to live work in substations. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention proposes a method for equipotentia...
