Abstract
The utility model relates to a grounding electrode and belongs to the technical field of power equipment. In the grounding electrode, the lower end of a flat iron is provided with graphite electrodes; the upper end of the graphite electrodes is provided with a square slot for being in inserted connection with the flat iron; the positions of the underground part of the flat iron, which are close to the graphite electrodes, are provided with graphite electrode parallel connection points; a plurality of graphite electrodes can be connected in parallel as required; a resistor test point is arranged at the position at the height of the shoulder of an adult above the ground line at which the flat iron is embedded; an insulation protective sleeve is arranged on the periphery of the resistor test point; an insulating sleeve is arranged in the space between 200mm below the ground line at which the flat iron is embedded and 2,500mm above the ground line; the insulating sleeve is disconnected at the position of the resistor test point; and the insulation protective sleeve is arranged at the disconnected position. The grounding electrode adopts the graphite electrodes and the hot galvanizing flat iron, so that the rust resistance function and the electric conduction effect are improved and the function of protecting protecting facilities for people, electric appliances and buildings is improved. Due to the arrangement of the resistor test point, the shock damage to a worker in the process of testing a resistor is avoided. The product of the grounding electrode is simple, convenient and easy to manufacture and use, is safe and reliable to test and maintain and has a service life of over 30 years.
Description
Technical field
The utility model belongs to electrical equipment technical field.
Background technology
At present; the transformer of power industry; the earth electrode that the lightning arrester of building is used; the modes that adopt band iron welding angle steel more; band iron installs the plastic tube insulating protective layer outward additional, and the problem of existence is band iron or angle steel easy-to-rust, and the corrosion thing is peeled off the formation air insulation; reduce conductive effect, people, transformer and building protective facility are lost defencive function.In addition, because prior art products is not provided with the resistance test point, implements resistance test and easily the staff is caused electric shock.
Summary of the invention
The purpose of this utility model provides a kind of earth electrode that is applied to transformer and lightning arrester; to solve prior art products band iron angle steel easy-to-rust; the corrosion thing is peeled off the formation air insulation; reduce conductive effect; people, electrical equipment and building are lost defencive function; and the resistance test point is not set, implement resistance test and easily the staff is caused problems such as electric shock.
The utility model mainly is made up of band iron, insulating protective layer, and solving the technical scheme that its technical problem adopts is in the lower end of band iron graphite electrode to be set, and graphite electrode is the cylindricality pole, and its upper end is provided with the square groove of grafting band iron.The band iron under ground portion is provided with graphite electrode and contact near the graphite electrode place, and graphite electrode and contact can and connect many root graphite electrodes as required for the circle open-work.Adult's shoulder height place is provided with the resistance test point more than the embedding horizon of band iron, and resistance test point adopts band iron to disconnect the punching connecting bolt and fixes, and resistance test point periphery is provided with insulating sheath.Following 200mm is provided with insulating sleeve to the horizon between the above 2500mm in the embedding horizon of band iron, and insulating sleeve disconnects at resistance test point place, and insulating sheath is set therebetween.
Adopting good effect of the present utility model is by adopting graphite electrode and hot galvanizing band iron, improved resistant to rust function and conductive effect, having improved the defencive function to people, electrical equipment and building protective facility.By the resistance test point is set, when having avoided resistance test to staff's electric shock.Its product has to be made simple for usely, and test maintaining is safe and reliable, and can reach more than 30 years useful life, greatly reduces to produce and application cost.
