Description

EQUIPO PARA LA LIMPIEZA DE CADENAS AISLANTES DE LÍNEAS DE TRANSMISIÓN DE ENERGÍA ELÉCTRICA  EQUIPMENT FOR THE CLEANING OF INSULATING CHAINS OF ELECTRIC POWER TRANSMISSION LINES
CAMPO TÉCNICO TECHNICAL FIELD
La presente invención se refiere a un equipo para facilitar la limpieza de cadenas aislantes de líneas de transmisión de energía eléctrica de alta tensión y súper alta tensión, las cadenas comprenden los aisladores de porcelana y de vidrio, en configuración de suspensión que están fabricados de materiales cerámicos, de vidrio o tecnología semejante. The present invention relates to a device for facilitating the cleaning of insulating chains of high voltage and super high voltage power transmission lines, the chains comprise the porcelain and glass insulators, in suspension configuration, which are made of materials ceramic, glass or similar technology.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
El mantenimiento del aislamiento eléctrico externo en ambientes con alta contaminación en lineas de transmisión tales como las líneas que están ubicadas en cercanía de la costa es imprescindible y debe realizarse constantemente; debido a que la costa es una zona desértica, ésta se caracteriza por la presencia de polvo, vientos fuertes y ausencia de lluvias, y todo esto sumado a la cercanía al mar, hace que las cadenas aislantes de líneas de transmisión de energía eléctrica requieran limpieza profunda y permanente para no afectar su funcionamiento y prevenir cualquier tipo de daño o riesgo a dicha infraestructura. Para ello, la limpieza del aislamiento se debe realizar con mucha frecuencia y por consecuencia los costos asociados a las líneas de transmisión se elevan, haciendo que el presupuesto de mantenimiento sea alto. También es aplicable en zonas donde la contaminación por polución sea elevada, no restringiéndose solo a líneas costeras. The maintenance of external electrical insulation in environments with high contamination in transmission lines such as lines that are located close to the coast is essential and must be done constantly; because the coast is a desert area, this is characterized by the presence of dust, strong winds and lack of rain, and all this added to the proximity to the sea, makes the insulating chains of electric power transmission lines require cleaning deep and permanent so as not to affect its operation and prevent any type of damage or risk to said infrastructure. For this, the cleaning of the insulation must be done very frequently and consequently the costs associated with the transmission lines are raised, making the maintenance budget high. It is also applicable in areas where pollution pollution is high, not restricted to coastal lines only.
Actualmente la operación de mantenimiento de las cadenas aislantes de líneas de transmisión de energía eléctrica se realiza manualmente y con gran desgaste y esfuerzo físico por parte de los operarios a cargo de esta función, siendo necesario que los operarios sean izados hasta el lugar donde se encuentran las cadenas aislantes y realicen el esfuerzo de limpieza manual de cada parte de dicho componente en una posición incómoda y de riesgo, lo cual, a largo plazo, trae como consecuencia el daño físico de los operarios. Currently the maintenance operation of the insulating chains of electric power transmission lines is carried out manually and with great wear and physical effort by the operators in charge of this function, being necessary for the operators to be hoisted to the place where they are located. insulating chains and carry out the effort of manual cleaning of each part of said component in an uncomfortable and risky position, which, in the long term, brings as a consequence the physical damage of the operators.
Para estas actividades de mantenimiento se requiere un gran número de trabajadores debido a las extensas áreas de mantenimiento en la zona costera y a lo tedioso y desgastante de esta actividad, siendo en consecuencia baja la productividad y eficiencia en el método tradicional de limpieza, ya que se requiere un elevado tiempo para la ejecución de estas tareas y existe un bajo rendimiento de los trabajadores siendo constantes las fatigas, el desgaste físico incremental y hasta lesiones. En la limpieza manual del aislamiento se usa gran cantidad de escaleras, hechas de fibra de vidrio o de aluminio, para el personal operario que se desplazará a lo largo de las cadenas de aislamiento. For these maintenance activities, a large number of workers are required due to the extensive maintenance areas in the coastal zone and the tedious and exhausting activity, with the consequent low productivity and efficiency in the traditional cleaning method, since It requires a high time for the execution of these tasks and there is a low performance of the workers being constant the fatigue, the incremental physical wear and tear and even injuries. In the manual cleaning of the insulation, a large number of ladders, made of fiberglass or aluminum, is used for the operating personnel who will move along the insulation chains.
De acuerdo a estudios realizados (por ejemplo, estudios de ergonomía para trabajos en líneas de transmisión presentados en el CITTES - Congreso Internacional de Trabajos con Tensión en Argentina organizado por el CACIER. http://sq.cier.orq.uv/Publicaciones/revista.nsf/0a293b20eacdf8a903257133003e a67d/65e4e6bca07fa5508325792d00466e66?OpenDocument), las lesiones ocasionadas se concentran en las manos, el cuello y la espalda de los operarios, esto debido al uso necesario del arnés anti caída para proteger y posicionar al personal de trabajo en los puntos donde efectuará la limpieza; en dicha operación, el peso del operario así como los ángulos en los cuales tienen que posicionarse para realizar la limpieza de todas las partes de los aislantes eléctricos, causan en los operarios un desbalance en la distribución de los esfuerzos propios de su peso, debido al trabajo realizado partes diferentes del cuerpo de los operarios se desgastan más en una postura que en otra, lo que a la larga demanda demasiado esfuerzo físico en los operarios, debido a esto se produce en los operarios un alto riesgo de sufrir daños, lesiones o dolores músculo-esqueléticos, obligando a los operarios a asistir permanentemente a centros médicos y de rehabilitación. According to studies carried out (for example, studies of ergonomics for work on transmission lines presented at the CITTES - International Congress of Works with Tension in Argentina organized by CACIER. Http: //sq.cier.orq.uv/Publicaciones/ revista.nsf / 0a293b20eacdf8a903257133003e a67d / 65e4e6bca07fa5508325792d00466e66? OpenDocument), the injuries caused are concentrated in the hands, neck and back of the operators, this due to the necessary use of the anti-fall harness to protect and position the work personnel in the points where he will carry out the cleaning; in this operation, the weight of the operator as well as the angles in which they have to position themselves to perform the cleaning of all the parts of the electrical insulators, cause in the operators an imbalance in the distribution of the own efforts of their weight, due to the Work done different parts of the body of the operators wear more in one position than in another, which in the long run demands too much physical effort in the operators, due to this there is a high risk of injury, injury or pain in the workers. musculoskeletal, forcing operators to permanently attend medical and rehabilitation centers.
La estadística muestra que en el sector donde mayor concentración de afectaciones y deterioros de este tipo se da, es en el personal destinado a la limpieza y mantenimiento de las líneas de transmisión de las empresas eléctricas. The statistics show that in the sector where the greatest concentration of damage and deterioration of this type occurs, it is in the personnel assigned to the cleaning and maintenance of transmission lines of electric companies.
En el estado de la técnica existen diversos dispositivos diseñados para intentar simplificar o automatizar la limpieza de los aislantes de líneas eléctricas y reducir el esfuerzo que deben realizar los operarios. En la mayoría de casos se trata de equipos complejos y de alto costo que utilizan, por un lado, el bombeo de agua para realizar esta función, en otros casos se utiliza la inyección de aire como medio de limpieza y existen también equipos que combinan la utilización de agua con medios de limpieza por fricción tales como cepillos. In the state of the art there are several devices designed to try to simplify or automate the cleaning of electrical line insulators and reduce the effort that operators must make. In most cases it is complex and high-cost equipment that uses, on the one hand, the pumping of water to perform this function, in other cases the injection of air is used as a means of cleaning and there are also equipment that combines the use of water with friction cleaning means such as brushes.
En ese orden de ideas, la patente CN205851456 divulga un dispositivo de limpieza de aisladores eléctricos de alto voltaje, consistente en un taladro de pistola con una barra reforzada en cuyo extremo tiene un cepillo limpiador conectado a una bomba de agua de alta presión a través de una manguera y boquilla de ducha.

A su vez, la Patente US2004168277 describe anillos de limpieza impulsados por el viento, dispuestos en cada disco de la cadena de aisladores, para eliminar la suciedad de un aislador utilizado en el sistema eléctrico. El anillo de limpieza consta de anillos aislantes impulsados por el viento, cepillos en los anillos dispuestos en las placas o discos. Los anillos de limpieza impulsados por el viento giran alrededor del aislador de esta manera el aislador permanece limpio. In turn, US2004168277 discloses cleaning rings driven by the wind, arranged in each disc of the chain of insulators, to remove dirt from an insulator used in the electrical system. The cleaning ring consists of insulating rings driven by the wind, brushes on the rings arranged on the plates or discs. The wind-driven cleaning rings rotate around the insulator in this way the insulator remains clean.
