Abstract
The utility model discloses an electroscope prolongation connecting device. The electroscope prolongation connecting device comprises a hollow sleeve, a bolt is weld at the upper end of the hollow sleeve, a nut matched with the bolt is arrange on the bolt, and a fastening device is arranged at the lower end of the hollow sleeve. The electroscope prolongation connecting device is simple in structure, is of low manufacturing cost, and is convenient to install and use. By employing the electroscope prolongation connecting device, an operator can check the electricity of equipment which is arranged at a high place, so that workloads and safety risks of the operator are reduced.
Description
Technical field
The utility model relates to electroscope and extends coupling arrangement, relates to electric construction tool technical field.
Background technology
Electroscope is the conventional a kind of managing security tools and instruments of transformer station.Whether this instrument is can checkout facility charged, guarantees equipment and personal safety.But in use find, the live part of some equipment is higher apart from ground, and traditional electroscope, because length is shorter, cannot touch charged position and carry out work.And insulating bar is the conventional another kind of instrument of transformer station, length is longer.If electroscope can be fixed on insulating bar and use, just can check the live part equipment higher apart from ground, solve the shorter inconvenience bringing of existing electroscope length, increase work efficiency.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of electroscope and extends coupling arrangement, and simple in structure, cost of manufacture is low, easy to install; Operating personnel just can carry out electrical verification to higher device on the ground, has reduced operating personnel's workload and the security risk facing.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of electroscope extends coupling arrangement, comprises that the upper end seal welding of cannulated sleeve, cannulated sleeve has bolt, bolt to be provided with the nut being mated; The lower end of cannulated sleeve is provided with fastener.
Fastener is 1/3rd of cannulated sleeve total length apart from the distance of cannulated sleeve lower port.
The lower end symmetry of cannulated sleeve be provided with two fasteners.
Described cannulated sleeve is made by steel pipe.
The beneficial effect that adopts technique scheme to produce is: the utility model is simple in structure, and cost of manufacture is low, easy to install; Operating personnel just can carry out electrical verification to higher device on the ground, has reduced operating personnel's workload and the security risk facing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
1 is cannulated sleeve, and 2 is bolt, and 3 is nut, and 4 is fastener.
Embodiment
Embodiment 1
Electroscope extends a coupling arrangement, comprises that the upper end seal welding of cannulated sleeve 1, cannulated sleeve 1 has bolt 2, bolt 2 to be provided with the nut 3 being mated; The lower end symmetry of cannulated sleeve 1 be provided with two fasteners 4;
Fastener 4 is 1/3rd of cannulated sleeve total length apart from the distance of cannulated sleeve lower port;
Cannulated sleeve 1 is made by steel pipe.
The steel pipe that uses the long 50mm of Ф 20mm, one end seal welding Ф 6mm bolt adds adjusting nut, at steel pipe opening 1/3rd place's punching mantle fibers, installs fastening bolt additional.
When the utility model is used, the montant of insulating bar upper end is inserted in cannulated sleeve, twisting fastener is fixed montant, by the bolt precession electroscope lower end of cannulated sleeve upper end, adjusting nut position.
Embodiment 2
Electroscope extends a coupling arrangement, comprises that the upper end seal welding of cannulated sleeve 1, cannulated sleeve 1 has bolt 2, bolt 2 to be provided with the nut 3 being mated; The lower end of cannulated sleeve 1 is provided with a fastener 4;
Fastener 4 is 1/3rd of cannulated sleeve total length apart from the distance of cannulated sleeve lower port;
Cannulated sleeve 1 is made by steel pipe.
The steel pipe that uses the long 50mm of Ф 20mm, one end seal welding Ф 6mm bolt adds adjusting nut, at steel pipe opening 1/3rd place's punching mantle fibers, installs fastening bolt additional.
Known, in electric system upkeep operation or in grid switching operation, must be in load side after open-circuit line block switch every cutter by phase electrical verification, after confirming without electricity, can pull open load side every cutter.Such sequence of operation, can avoid on-load broaching tool lock.But in actual mechanical process, due to on-pole switch, install not at same shaft tower every cutter, universal along with the special shaft tower of city rural power grids again, without the suitable bar instrument of stepping on, crossing many canopies cross-arm just can touch every cutter with traditional electroscope, though tradition electroscope insulation shrinkage arm meets minimum safe distance, stands in before use ground and be difficult to contact electrification equipment in check, must ascend a height.A lot of people dislike trouble, and think and make an unnecessary move, and after open-circuit line block switch, only with switch separating brake sound and sense organ, conclude that load side line is without electricity, thus omitted first in load side every this important step of cutter electrical verification.Doing is like this danger close, supposes that the objective factors such as the indication of on-pole switch mechanism is malfunctioning, the inner dynamic/static contact of switch gap is little exist, and consequence is by hardly imaginable.Strictly by working specification operation lower beam in electrical verification, the solution inconvenience of fastening the safety belt of just ascending a height, city net segmentation pole top switch lever is mostly high-low pressure and crosses lower canopy cross-arm with bar hypothesis, increases the possibility of getting an electric shock, and also increases operator's physical demands, extend the running time, the problems such as inefficiency.For solving conveniently electrical verification problem, electroscope and insulating bar can be linked together, just can on ground, carry out electrical verification, the utility model has well solved the problems referred to above.
