Description
Technical Field
The utility model relates to a branch line backup protection device belongs to power equipment technical field.
Background
When triangular arrangement branch detaching and bridging work is carried out in 10KV distribution network live-line work, some T-connection branches have structural defects, and the tail lines of the original detached branches are upwards stressed and lapped in the electrified main lines. Because of the broken T-junction branch, the sag of the branch is suddenly increased (which is more dangerous if the branch is a bare conductor) and the side of the electrified main line is seriously insufficient or directly close to each other. During live working, even if insulation protection measures are taken on the branch line to be disconnected, the branch line cannot directly lean on a main line with electricity, because the main insulation protection of the live working still depends on air. Other measures are only auxiliary insulation and are only suitable for wiping contact at different potentials in the live working process. Therefore, when the similar work is met, the insulating bucket can only be operated by the hot-line workers, the branch line is pulled away from the main line by the aid of the handheld insulating rope to keep an effective distance until the branch line is dismantled to overhaul, physical consumption of the hot-line workers is greatly increased by the aid of the operation, and the whole operation process is in a dangerous uncontrollable environment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a branch line backup protection device solves and is torn open the problem that the effective interval undersize of branch line and electrified mainline is not conform to safety standard to guarantee branch line maintainer's safe work also reduces the live working personnel high altitude cooperation degree of difficulty simultaneously, improves live working's work efficiency.
The purpose of the utility model is realized through the following technical scheme:
a branch backup protection device comprises a cross arm fixing piece, an insulating rod, a branch slot plate and a lead hole; the cross arm fixing piece comprises a seven-shaped clamping groove and a compression bolt, the insulating rod comprises an insulating rod lower section and an insulating rod upper section, threaded holes are respectively formed in two end faces of the insulating rod lower section, the compression bolt penetrates through a fixed hole of the seven-shaped clamping groove and then is screwed into a threaded hole in one end of the insulating rod lower section, the seven-shaped clamping groove and the insulating rod lower section are fixed, a screw rod is arranged at one end of the insulating rod upper section and matched with a threaded hole in the other end of the insulating rod lower section, the insulating rod upper section and the insulating rod lower section are screwed and connected, branch line groove plates are respectively arranged at the bottom of the insulating rod upper section in a bilateral symmetry mode, and lead holes are respectively arranged at the.
The purpose of the utility model can be further realized through the following technical measures:
in the branch backup protection device, the branch slot plate and the lead hole are made of epoxy resin plate.
The branch line backup protection device further comprises a limiting bolt, a threaded hole is formed in the side face of the lower section of the insulating rod, and the limiting bolt is screwed into the threaded hole and then compresses the screw rod to be positioned.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses to be torn open the branch line and put and make the branch line obtain fixed guarantee to the distance that has the electricity thread in the branch line frid that is fit for the operation direction. The possibility that the sag of the T-connection branch line is gradually increased to cause 'insufficient distance to different potentials at the same time' and potential safety hazards to human bodies and lines can be caused can be avoided. Then remove the electrification and demolish the middle phase branch line, the tail wire of the branch line penetrates the lead hole of the device to fix. The problem that the effective distance between the detached branch line and the electrified main line is too small to meet the safety standard is solved, and the safety work of branch line maintainers is guaranteed.
Drawings
Fig. 1 is a structural view of the present invention.
Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
As shown in fig. 1, the utility model discloses a branch line backup protection device, including cross arm mounting, insulator spindle, spacing bolt 3, branch line frid 4, pin hole 5 are made by the epoxy board, and epoxy has characteristics such as density height, water-resistant, anti seepage are good, and its dielectric strength can satisfy the 10KV and join in marriage net live working's operation requirement. The cross arm fixing piece 1 comprises a seven-shaped clamping groove 11 and a compression bolt 12, the insulating rod 2 comprises an insulating rod lower section 21 and an insulating rod upper section 22, threaded holes are respectively formed in two end faces of the insulating rod lower section 21, the compression bolt 12 penetrates through a fixed hole of the seven-shaped clamping groove 11 and then is screwed into a threaded hole in one end of the insulating rod lower section 21, the seven-shaped clamping groove 11 and the insulating rod lower section 21 are fixed, a screw rod 6 is arranged at one end of the insulating rod upper section 22 and is matched with a threaded hole in the other end of the insulating rod lower section 21, the insulating rod upper section 22 and the insulating rod lower section 21 are screwed and connected, a threaded hole is formed in the side face of the insulating rod lower section 21, and the compression bolt 6 is positioned after the limiting bolt. The bottom of the upper section 22 of the insulating rod is symmetrically provided with branch trough plates 4, and the top of the upper section 22 of the insulating rod is symmetrically provided with lead holes 5.
The device is used for electrically disconnecting the phase of the T-connection branch line, potential safety hazards exist in the safety distance between the branch line needing power failure and the electrified main line under the condition, even if insulation protection is carried out on a working site at the time, all safe operation requirements cannot be met, and workers who overhaul the branch line are seriously endangered.
When the branch backup protection device is used, an operator firstly holds the cross arm fixing piece and the lower section of the insulating rod, which can be fixed with the cross arm, of the device, keeps a proper safety distance, then firmly connects the seven-shaped clamping groove of the cross arm fixing piece with the cross arm through the compression bolt and vertically installs the cross arm, firmly connects the upper section of the insulating rod with the lower section of the insulating rod, and clamps the upper section of the insulating rod with the lower section of the insulating rod through the limiting bolt. And according to the fact that the direction of the T-connection branch line is deviated to the left or right, the detached branch line is placed in a branch line trough plate suitable for the operation direction. At this time, the distance between the branch line and the wired main line is fixedly guaranteed. The possibility that the sag of the T-connection branch line is gradually increased to cause 'insufficient distance to different potentials at the same time' and potential safety hazards to human bodies and lines can be caused can be avoided. Then remove the electrification and demolish the middle phase branch line, the tail wire of the branch line penetrates the lead hole of the device to fix. Thus, the removed branch line phase can keep an effective and safe distance with the electrified main line phase, the expected protection effect is achieved, and the safety of the type of work is greatly improved.
