Description
Technical field
The present invention relates to 10KV, to fall the electrical verification of fuse to cable earthy, is installed in to fall under the fuse device between terminals to the high-tension cable head.
Background technology
Electric power safety regulation must be in the working point of cable two end hanging earthing conductors; And electrified body must be left more than 0.7 meter in the working point; Prior art owing to do not have electrical verification and earth point, can't connect earth connection when work; There not being electrical verification to articulate dangerous operation under the situation on ground, relate to the problem of personal safety.Therefore the applicant had once designed " adjusting connection type electricity testing grounding ring ", and had applied for Chinese patent, and application number is 200910096716.5; Its structure comprises that processing ring by conductor material forms with straight-bar, encircle and straight-bar outside insulating sleeve is arranged, one of ring is that ground connection dew is managed; The straight-bar head is connected with the first terminal, and the first terminal flexibly connects angle adjustment plate, and hanging hole is arranged on the angle adjustment plate; Hanging hole with fall fuse device and be connected, in the ring bottom second terminal is arranged, the second terminal connects the 10KV threephase cable.The shortcoming that this structure exists is: straight-bar is a stiff rod, can't be crooked, and need to lean on angle adjustment plate and fall fuse device and be connected; Complex structure, connective stability is poor, connects dumb; And this electricity testing grounding ring is vertically to install, and need reduce lower floor's low-voltage line during installation, influences line-spacing.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming that prior art exists; Provide a kind of fuse device to cable end that falls that regular electrical verification earth point is set, filled up prior art and fallen the blank that does not have the electrical verification earth connection between fuse device to the high-tension cable, and connect flexible, good stability; Do not stop to disconnect cable under the situation of main line; Do not reduce lower floor's low-voltage line, do not excavate road, bury the underground high-voltage line; Can be directly road sit astride on a horse, the big 10KV of line-spacing falls fuse cable electrical verification earth connection simultaneously and between lower floor's low-voltage line.
The technical scheme that 10KV of the present invention falls fuse cable electrical verification earth connection is: be included in install on the cement pole with close load, and close load one side and be connected and fall fuse device, opposite side connects the support porcelain vase; Support the porcelain vase lower end to connect the electrical verification earth connection; The electrical verification earth connection connects the high-tension cable head, it is characterized in that said electrical verification earth connection comprises the square ring body of being processed by conductor material, and square ring body connects connecting line; Square ring body and connecting line have the silicon rubber insulation sheath outward; Wiring point under the fuse device is fallen in a connection of connecting line, is electrical verification earth point, electrical verification earth point hanging earthing conductor at one of square ring body; Be shaped on the high-voltage cable wiring point in the bottom of square ring body, the high-voltage cable wiring point is connected with the high-tension cable head.
The invention discloses a kind of 10KV and fall fuse cable electrical verification earth connection, falling the horizontal electrical verification earth connection of installing between fuse device and the high-voltgae pothead, high-low pressure is joint used circuit; Need not reduce lower floor's low-voltage line, line-spacing is big, and the square ring body of being processed by conductor material connects connecting line; Connecting line is soft lead, and connecting line is when falling fuse device and be connected, and connecting line can be arbitrarily crooked according to the position of falling fuse device; Simple in structure, connection is flexible, convenient, good stability; This programme 10KV falls fuse cable electrical verification earth connection, both has been used for electrical verification ground connection, is used for the whole piece circuit again and is connected to branch line or service cable; Solve and filled up and fallen the blank that does not have regular electrical verification grounding technology between fuse device to the high-tension cable head, can under the situation of not stopping main line, disconnect cable, guaranteed the reliability of power supply.After this electrical verification earth connection has been installed on the line; Can directly stride across road (highway); When having overcome existing high-tension cable and having gone across the road, change low-voltage circuit into or with high-tension line through the excavation road, could be with underground cable through shortcomings such as construction trouble that road was brought, expense height.
10KV of the present invention falls fuse cable electrical verification earth connection, and said high-voltage cable wiring point is equipped with rain cover outward.Rain cover has been arranged, prevented wiring place water inlet.Said square ring body links to each other with the connecting line crimping.Said connecting line other end fall the fuse device wiring point to square ring body maximum distance L be 1 meter.Distance is far away more, guarantees staff's safety.Described connecting line is copper conductor or aluminum conductor, and the silicon rubber insulation sheath is arranged outside copper conductor or aluminum conductor.
