Abstract
The invention discloses a kind of earth lead protection device; ground protection block is made up of sheath, conducting ring, sealing ring and moistureproof filler; sheath center sets unwrapping wire pipe; the uniform annular protrusion axially vertical with unwrapping wire pipe of its outer wall; and it is one-body molded with sheath; sealing ring at least two sets cable-through hole in the middle of it; and be distributed on from sheath top inside sheath; and two arrange moistureproof filler between sealing ring and between sealing ring and jacket inner wall; conducting ring at least 3; being distributed in inside unwrapping wire pipe, conducting ring separately sets wiring hole, separately sets conductive paste layer in wiring hole.The earth lead tool that the present invention is more traditional, improving and between the earth while electric conductivity, improve the corrosion resistance of earth lead, effectively extend earth lead Acceptable life, decrease detection number of times, and greatly facilitate earth lead detection and replacement operation, while promoting electrical equipment grounding reliability, the labor intensity reduce earth lead detection, safeguarding and changing, improves circuit and ensures working performance.
Description
Technical field
The present invention relates to a kind of earth lead protection device, belong to power protection technology field.
Background technology
nullEarth lead is to realize electrical system and the formation isoelectric level that is greatly connected，Thus reach electrical system、Operator and the purpose of combustible and explosive area electic protection，Its use is quite varied，And the numerous electrifications appeared in reality，Trace it to its cause，The imperfect earth that great majority are because being caused by reasons such as environmental corrosions after earth lead uses for a long time causes，The lighter causes because of electrical equipment tripping operation or damages the accident that causes power failure，Personnel even can be caused to get an electric shock time serious、The major accidents such as initiation fire，In order to overcome this problem，At present when connecting wires laying，Often use and strengthen what earth lead line diameter ratio was practised in the spraying of earth lead outer surface or electroplating anticorrosion erosion layer，But the progress that this kind of way has the most only delayed earth lead to corrode，It is thus desirable to periodically earth wire detects and changes，Detection time interval is generally about 1 year，But the most almost do not have within individual month, will detect in the area that corrosivity is serious，On the one hand labor intensity is added，On the other hand also great hidden danger is brought to safe operation of power system.
Summary of the invention
The object of the invention is that and overcomes above-mentioned deficiency, it is provided that a kind of earth lead protection device and laying method.
For achieving the above object, the present invention is to be achieved through the following technical solutions:
A kind of earth lead protection device, described earth lead protection device is by sheath, conducting ring, sealing ring and moistureproof filler are constituted, described sheath center sets unwrapping wire pipe, the uniform annular protrusion axially vertical with unwrapping wire pipe of its outer wall, described annular protrusion diameter is at least unwrapping wire pipe diameter 1 times, and it is one-body molded with sheath, described sealing ring at least two sets cable-through hole in the middle of it, and be distributed on from sheath top inside sheath, and two arrange moistureproof filler between sealing ring and between sealing ring and jacket inner wall, described conducting ring at least 2, it is distributed in inside unwrapping wire pipe, conducting ring separately sets wiring hole, conductive paste layer is separately set in wiring hole, conducting ring and unwrapping wire inside pipe wall gross contact area are not less than the 1/3 of the unwrapping wire inside pipe wall gross area.
Ground protection block is cylindrical.
Ground protection block is cone, and the vertex of a cone is downward.
Sheath material is conducting metal material.
The earth lead tool that the present invention is more traditional, improving and between the earth while electric conductivity, it is greatly improved the corrosion resistance of earth lead, effectively extend earth lead Acceptable life, decrease detection number of times, and greatly facilitate earth lead detection and replacement operation, while promoting electrical equipment grounding reliability, the labor intensity reduce earth lead detection, safeguarding and changing, improves circuit and ensures working performance.

Detailed description of the invention
nullAs illustrated in fig. 1 and 2，A kind of earth lead protection device，Described earth lead protection device is by sheath 1、Conducting ring 2、Sealing ring 3 and moistureproof filler 4 are constituted，Described sheath 1 center sets unwrapping wire pipe 5，The uniform annular protrusion 6 axially vertical with unwrapping wire pipe 5 of its outer wall，Described annular protrusion 6 diameter is at least unwrapping wire pipe 5 diameter 1 times，And it is one-body molded with sheath 1，Described sealing ring 3 at least two sets cable-through hole 7 in the middle of it，And it is internal to be distributed on sheath 1 from sheath 1 top，And two arrange moistureproof filler 4 between sealing ring 3 and between sealing ring 3 and sheath 1 inwall，Described conducting ring 2 at least 2，It is distributed in unwrapping wire pipe 5 internal，Conducting ring 2 separately sets wiring hole 8，Conductive paste layer 9 is separately set in wiring hole 8，Conducting ring 2 and the unwrapping wire pipe 5 contact internal walls gross area are not less than the 1/3 of the unwrapping wire pipe 5 inwall gross area.
During use, the most just earth lead installs location with sealing ring and conducting ring respectively by cable-through hole and wiring hole, then wire is progressively arranged in sheath together with sealing ring and conducting ring, installing simultaneously and filling moistureproof filler, finally device can carried out earth lead landfill by sheath spraying corrosion resistant coating and install.
