Abstract
The utility model relates to an earth electrode resistor device used for a power distribution network, and is characterized by comprising a carbon rod (2); wherein a fixture (1) is fixedly arranged at one end of the carbon rod (2), and the fixture (1) is provided with a wiring terminal or wiring hole. The earth electrode resistor device of the utility model has the beneficial effects that: the area of an earth electrode of the power distribution network is increased, and an earth resistance value is reduced; an earth resistance of the earth electrode of the power distribution network is reduced, thus the service life of the earth electrode of the power distribution network is prolonged, and personal safety of maintenance personnel and construction personnel is raised; by adopting the carbon rod earth electrode, the phenomenon that a large number of steel materials are corroded every year can be avoided; and conditions for realizing an intelligent power distribution network can be provided.
Description
Technical field
The utility model relates to a kind of power distribution network earth electrode resistance device.
Background technology
In electric power system, the quality of grounding system directly has influence on stability and the reliability of power distribution network operation.In construction and some problems that usually run in service of grounding system, existing earth electrode is zinc-plated on angle bar, easily forms primary cell at present, and corrosion phenomenon is more serious, uses at most 5 years, needs to change earth electrode, has a strong impact on efficiency of construction and safe operation.
Present power distribution network uses grounding galvanizing steel ground connection usually, form easily primary cell, accelerated corrosion, cause the against regulation requirement of earth resistance, the technical problem such as service life is short is found through in many ways detecting, use after 1,2 year, because corrosivity is more serious, angle steel earth electrode resistance generally at 25 to 50 ohm, obviously exceeds demand of technical standard.
The utility model content
The purpose of this utility model provides a kind of long service life, the good power distribution network of ground connection earth electrode resistance device.
A kind of power distribution network earth electrode resistance device, its special feature is: comprise a carbon-point, be installed with jig at this carbon-point one end, be provided with binding post or wiring hole at this jig.
Wherein jig adopts copper or aluminium material, and this jig directly contacts with carbon-point.
Wherein carbon-point be cylindric and this carbon-point on be provided with coniform tip away from the other end of jig.
The employing the beneficial effects of the utility model are: the one, increase power distribution network earth electrode area, and reduce grounding resistance; The 2nd, reduce power distribution network earth electrode earth resistance, prolong the power distribution network earth electrode life-span, improve maintainer, workmen's personal safety; The 3rd, use by adopting the carbon-point earth electrode, avoided annual great deal of steel by eroding in vain; The 4th, provide condition for realizing the intelligent power distribution net.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of power distribution network earth electrode resistance device, comprises a carbon-point 2, is installed with jig 1 at these carbon-point 2 one ends, is provided with binding post or wiring hole at this jig 1.
Wherein jig 1 employing copper or aluminium material, and this jig 1 directly contacts with carbon-point 2, and carbon-point 2 is provided with coniform tip for the other end away from jig 1 on cylindric and this carbon-point 2.
Process experiment showed, that earth electrode resistance device resistance value of the present utility model meets the requirements fully, and not perishable, surpasses existing galvanized angle iron earth electrode useful life.
Claims (3)
