Description
Technical field
The utility model belongs to electric power overhead transmission line deicer technical field of structures.
Background technology
The south of experience at the beginning of 2008 is the ice damage accident on a large scale, and especially extensive, deep research has been carried out in the anti-icing and the deicing of transmission line and overhead ground wire to work about electric power person for adopting variety of way to carry out power equipment.From present applicable cases, prevent that the measure of power equipment and powerline ice-covering all is in laboratory stage, can't be applied to engineering reality.The powerline ice-covering on-line monitoring system of installing can be monitored and reports to the police the circuit icing situation of partial points (counting according to monitoring location and cloth), but can't handle ice damage.Exchange de-icing technology and be subject to technical parameters such as line impedance, the power supply capacity that needs to cooperate has exceeded normal ranges, and applicable scope is little; DC ice melting more effectively is applied to engineering reality after the exploitation difficult point of solving device, and manifests its gratifying effect, but is subject to the economic benefit ratio, some is installed on a large scale is unable to stand, and this dual mode range of application only is confined to transmission pressure.
The ice-melt of heating power method makes its thawing owing to will release energy to ice cube, the DIRECT ENERGY supply of its requirement is maximum, adopting big electric current to carry out remote alternating current-direct current ice-melt can implement, if but at the circuit scene, the deicing means that employing is similar to the heating power method are not more excellent measure because need on-the-spot logistics support (energy supply) too greatly, too difficult.Particularly for overhead ground wire, owing to adopting tower grounding mode step by step now substantially, even the ice-melting mode of similar current method also is to be difficult to operation at the scene.
It is a kind of optional mode that Mechanical Method is applied to deicing, just melt 1/2000000～1/100000 of this ice cube institute energy requirement for the ice energy needed of sizing for its broken one, all in all, the Mechanical Method deicing only needs about 1/200 of thermal methods institute energy requirement, but such measures need be by means of artificial and apparatus under the normal condition.From pure technical standpoint, often mechanical system some do not become a mandarin, too the tradition.If but ensure that from accident when the low temperature hazard weather taking place have influence on the transmission line safe operation, power supply department must be made effective reflection, at this moment the staff to rush towards the disaster-affected line scene be possible, right or even necessary.
The staff who rushes to the disaster-affected line scene faces which kind of mode of employing is immediately removed icing on the circuit, and then the problem of assurance line security operation, circuit is stable sometimes greater than simple economic benefit ratio this moment, when these conditions possessed simultaneously, the mechanical type de-icing method that some technology content is not high can use.The experience and lessons of ice damage in 2008 are told us, and the ice damage field operation is stepped on something that tower is a crisis staff safety, and is promptly infeasible.At this moment the staff to adopt which kind of mode to carry out deicing under shaft tower next door or tower the most effective.
Actual conditions investigation based on above-mentioned proposes a kind of similar vibration method deicing mode.Its deicing object specially refers to overhead ground wire, by overhead line structures is transition conduction basic point, by transition conduction basic point and lead-in wire the lightning conducter rigidity is drawn and to be connected to ground location, when near the lead-in wire the ground, sealing in or incorporating vibration source (middle-size and small-size machine into, can be loaded on the car and carry, cost is limited, the energy supply is not high, operating time is not long) after, after can realizing the overhead ground wire icing, the field personnel uncarts vibration source on the rigidity lead wire of floor mounted at lightning conducter, but the people is the machinery " shake " that causes lightning conducter, reaches the effect of abolishing icing on the line.Need be installed on the overhead line structures only is some special gold utensils, rigidity buckle, steel strand wire etc., there is not electric, electronic equipment, promptly non-maintaining, before arriving early winter, articulated lead wire, personnel carried vibration source to field operation when icing was arranged, and took away vibration source after finishing, and removed (or packing up) lead wire after the beginning of spring, whole cost is low, and effect is good.
