Description
Technical Field
The invention relates to the field of power line operation, in particular to a self-ignition type fault source peeping positioning device.
Background
Because the transmission lines are widely distributed and operate in the open air for a long time, the transmission lines are often influenced by the change of the surrounding environment and the nature, so that various faults can occur in the operation of the transmission lines. The line fault means that the line power supply is suddenly interrupted due to various reasons, the accident is only reflected quickly after the accident occurs, firstly, the accident point is found and the accident type is determined, the line fault inspection is not a tourist flower, is convenient and convenient, but can be followed by a certain rule, and a good fault inspection sequence is formed, so that unnecessary time waste can be reduced, and the fault point is not missed.
Classification of transmission line faults: 1. ice damage fault 2, wind damage fault 3, lightning fault 4, pollution flashover fault 5, external force fault 6, galloping fault 7, bird damage fault 8, and other faults.
The operation experience shows that in various short-circuit faults of a power system, a single-phase short circuit accounts for most of the short-circuit faults of the power system, namely 65% of the total short-circuit faults, the short-circuit faults have a common point, when the single-phase short circuit occurs in the wind damage faults, the lightning faults, the pollution flashover faults and the bird damage faults, no matter what reason the lead discharges electricity to the pole tower, the pole tower forms a current channel, and when leakage current flows through the foundation of the pole tower, the bolts of the grounding connecting plate slightly melt traces. The phenomenon is that when the leakage current of a lead passes through the ground through a tower (conductor), a connecting hole of a grounding wire of the tower and a connecting plate bolt of a grounding downlead form a resistor node on the way, the current impedance of the resistor node forms a potential difference to the ground current, when the current passes through the resistor node, the potential difference rises to form an impact current to generate an electric arc, the electric arc causes burn marks to be formed at the connecting hole of the grounding wire and the connecting plate of the grounding downlead, when the effect of the impact current discharge burn marks is obvious, the point can be judged to be a fault point through visual inspection, when the discharge amount of the impact current is small, the small discharge burn marks are usually hidden in the angle iron panel and the grounding connecting plate of the tower body, and the fault inspection personnel can hardly observe the electric burn marks visually, so that the condition of line fault inspection and omission of the fault.
The transmission line operation unit needs to arrange personnel to carry out fault inspection once for finding out a line fault point, a fault reason and a fault condition, and the fault inspection does not find the fault reason and needs to carry out whole-line tower inspection so as to supplement the defect of normal inspection on the ground. Modern electric power transmission system gradually rapidly develops to the direction of high voltage, big leap, large capacity, and transmission line strides greatly, and long distance's electric power transmission makes a transmission line shaft tower numerous, and climbing shaft tower patrols and looks like prior art, because the restriction of operation device condition, climbing error, the physical strength of climbing shaft tower operation personnel are not enough, directly endangers operation personnel's personal safety, is the great potential safety hazard of electric power system operation, maintenance operation.

As shown in the attached drawings 1-6, the invention comprises an iron tower angle iron 2, a medicine box and a connecting plate 6 which are sequentially and tightly connected through a bolt 1 and a nut 8, wherein an inflammable tablet 4 is placed in the medicine box, a gap is formed on the medicine box so that the inflammable tablet 4 can be directly observed from the outer side, through holes 9 for the bolt to pass through are formed in the iron tower angle iron 2, the medicine box and the connecting plate 6, the bolt 1 sequentially passes through the through holes in the iron tower angle iron 2, the medicine box and the connecting plate 6, and then the other end of the screw is fastened through the nut. The connecting plate 6 is connected with a grounding down lead 7.
The medicine box is including mutual lock and the same left buckle 3 of structure and right buckle 5, left side buckle 3 is including plate body 301 and set up the annular arch 302 on plate body 301 outer edge, the space of right side buckle 5 and the cooperation of annular arch 302 between the buckle about is cylindrical, forms the space that is used for placing inflammable tablet 4. Evenly be equipped with a plurality of arc breach 10 on controlling the outer edge of buckle, arc breach 10 has 6 in this embodiment, and the buckle is plum blossom form about the messenger, and two buckles are in mutual lock, and the relative installation of arc breach forms a great breach, can directly observe the state that is located its inside inflammable tablet 4 from breach department, and the personnel of being convenient for patrol observe.
The combustible tablet 4 may be made of a material which is mechanically mixed with potassium nitrate, charcoal and sulfur (e.g., black powder), a burning agent caused by arc ignition, or a composition comprising various kinds of minerals: potassium nitrate, sulfur powder, and the like: the alloy material comprises titanium oxide more than or equal to 35 percent, ferromanganese, ferrotitanium wood powder, starch titanium dioxide, water glass and the like, and is filled with an alloy agent, an adhesive, a plasticizer, an elasticizer and the like. In summary, it is sufficient that combustible tablets 4 of the invention can be burnt under the action of an electric arc, without being constrained to a specific percentage between the individual components. The inflammable tablet is pressed into a wafer shape, and after the tablet is formed, a transparent PVC protective film is coated on the surface layer of the tablet by adopting a cold mounting technology, so that the tablet is prevented from being damaged, polluted or wetted, and the purpose of protecting the tablet is achieved.
