Description
Technical field
The present invention relates to power circuit erection technique field, install particularly to a kind of safe and reliable fall insurance switch
Method.
Background technology
In construction of line engineering, the installation site of fall insurance switch (drop out fuse) is in high-tension line and low pressure
The joint of circuit, widely as distribution power transformation device and the overload of circuit and short-circuit protection and control in 10kV high-pressure system
Circuit；And the obvious cut-off point that the electrical equipment overhauled and have a power failure or circuit arranged as playing buffer action.
Its installation method is extremely important, and it installs the safe operation being related to whole high-and low-voltage circuit and lifting in maintenance
Act on.
As it is shown in figure 1, in prior art, it is provided with the cross-arm 3 that rolls off the production line between electric pole 1 and electric pole 22, falls cross-arm 4, lightning-arrest
Device cross-arm 8, the fall insurance being connected on respectively in A phase, B phase, C phase switch A 6, fall insurance switch B 7 and fall insurance switch C
5 are installed in and fall on cross-arm 4, and horizontally arranged；And only zinc oxide surge arresters 9 on spark gap cross-arm 8；Before spark gap 9, circuit
It is connected to comprehensive distribution box 11 through transformator 10.
During the upgrading of rural power grids, three fall insurance switches are arranged on same cross-arm, and three fall insurance switch level
Arrangement, zinc oxide surge arresters on an other cross-arm below.This kind of mounting means, can not well ensure whole height line ball
The safe and reliable operation on road, especially under the severe weather conditions such as strong wind, deliver, pull open fall insurance switch time easily cause arc
Light short circuit phenomenon.
Summary of the invention
In order to make up the deficiencies in the prior art, the invention provides a kind of safe and reliable fall insurance switch installation side
Method.
The technical scheme is that
A kind of safe and reliable fall insurance switch installation method, is provided with spark gap cross-arm 8, falls between electric pole 1 and electric pole 22
Fall cross-arm 4, roll off the production line cross-arm 3, A phase, B phase, C phase line by comprehensive distribution box 11 after transformator 10 respectively through spark gap cross-arm
8, falling cross-arm 4 and the cross-arm 3 that rolls off the production line, A phase, B phase, C phase line are mounted on spark gap 9, and A phase, B phase, C phase line are also distinguished
Fall insurance switch A 6, fall insurance switch B 7 and fall insurance switch C 5 are installed；Described fall insurance switch A 6 with
Fall insurance switch C 5 is installed in and falls on cross-arm 4, and described fall insurance switch B 7 is arranged on spark gap cross-arm 8.
Preferably, the spacing between described fall insurance switch A 6 and fall insurance switch C 5 be 1.0 meters-
1.4 rice.This distance range is to take into account (the double rod type distribution that the safe distance saved between construction material and each discharge cock obtains
Criterion distance between transformer rack two electric pole is 2.5-2.8 rice).If this is apart from excessive, it is necessary for increasing the length of cross-arm
Degree, wastes material.If this is apart from too small, just do not reach the safe distance between each insurance, do not meet relevant design standard.
Preferably, falling the spacing between cross-arm 4 and spark gap cross-arm 8 described in is 1.0 meters-1.3 meters.This height
Scope is to take into account transformator height in vertical direction, fall cross-arm, spark gap cross-arm, lower cross-arm and each group of top circuit cross-arm
Distance between part obtains.Owing to this altitude range that limits of pole height can not be excessive；And scope is the least does not just reach two
Safe distance between person, does not meets relevant design standard.
Further, described fall insurance switch A 6, fall insurance switch B 7 and the company at fall insurance switch C 5 center
Line constitutes equilateral triangle.
Preferably, described spark gap 9 is installed on spark gap cross-arm 8.
The invention have the benefit that
Fall insurance is switched A 6 and fall insurance switch C 5 by the present invention be arranged on and fall on cross-arm 4, and by fall insurance
Switch B 7 is arranged on spark gap cross-arm 8, and fall insurance switch A 6 and fall insurance switch C 5 switchs B 7 with fall insurance
Not being arranged side by side, but be triangularly arranged, the spaced apart of fall insurance switch increases between phase and phase.The installation side of the present invention
Method, delivers, arc distance when pulling open fall insurance increases, and also makes fall insurance switch arc under the adverse weather conditions such as strong wind
The probability of light short circuit reduces several times, reduces accident rate, so that the security reliability that high-voltage line falls is greatly increased.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, also may be used
To obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of fall insurance switch installation method in prior art；
Fig. 2 is the structural representation of fall insurance of the present invention switch installation method.
Detailed description of the invention
Embodiment 1
As in figure 2 it is shown, a kind of safe and reliable fall insurance switch installation method, it is provided with lightning-arrest between electric pole 1 and electric pole 22
Device cross-arm 8, fall cross-arm 4, roll off the production line cross-arm 3, A phase, B phase, C phase line by comprehensive distribution box 11 after transformator 10 respectively through
Spark gap cross-arm 8, fall cross-arm 4 and the cross-arm 3 that rolls off the production line.
A phase, B phase, C phase line are mounted on spark gap 9, and spark gap 9 is installed on spark gap cross-arm 8.
Also it is separately installed with fall insurance switch A 6, fall insurance switch B 7 on A phase, B phase, C phase line and falls guarantor
Danger switch C 5；Fall insurance switch A 6 is installed in fall insurance switch C 5 and falls on cross-arm 4, fall insurance switch B 7
It is arranged on spark gap cross-arm 8.Spacing between fall insurance switch A 6 and fall insurance switch C 5 is 1.0 meters-1.4 meters.
