Description
Technical field
This utility model relates to a kind of squash type lightning-proof grounding body connector, refers more particularly to the connector of the conventional graphite bonded earth electrode in power system lightning protection field.
Background technology
For a long time, transmission line of electricity and power plants and station grounded screen generally use steel, copper or the metal material such as galvanized steel, copper covered steel.Metallic ground material corrosion problem is the bottleneck place of grounded screen life-time service, it is however generally that, steel grounding body 8～within 10 years, be accomplished by change.In recent years, graphite was combined earthing material as a kind of novel grounded material, efficiently solves the etching problem of metallic ground material, is widely used in transmission line of electricity and power plants and station grounded screen.
Electric welding cannot be carried out as tradition steel owing to graphite is combined earthing material, also heat release weldering cannot be used to be attached as copper product, therefore, when practice of construction uses, need to use the part that distinguishingly continues to be attached.And graphite bonded earth electrode junction point is often mechanical property weak spot, its switching performance is directly connected to grounding resistance and the Long Service Life of whole grounded screen.Therefore, design and Implement have be reliably connected performance, the corrosion-resistant aging graphite bonded earth electrode part that continues has engineering significance.
Summary of the invention
The feature that conventional welding manner cannot be used to be attached for the existing bonded earth electrode of graphite on the market, this utility model provides the connector in a kind of suitable power lightning protection field, effectively strengthens the bonding strength of graphite bonded earth electrode, substantially increases graphite and be combined the life cycle management of grounded screen.Additionally, squash type lightning-proof grounding body connector described in the utility model has the advantages such as simple structure, quick construction, low price.
For achieving the above object, technical solution adopted in the utility model is as follows:
A kind of squash type lightning-proof grounding body connector, it is characterized in that, described lightning-proof grounding body connector includes square shell, wedge shaped squeeze part and retaining bolt three part, described square shell is provided with oval connecting hole, article two, graphite bonded earth electrode is through described oval connecting hole, the reserved part that described graphite bonded earth electrode exposes after passing connecting hole is at more than 60mm, described wedge shaped squeeze part entirety is wedge shaped, bottom surface angle is consistent with the ramp angles of described oval connecting hole, described wedge shaped squeeze part top-most-surface plane arranges spill through slot, described retaining bolt is double threaded screw fitted bolt, single ended bolt, single head screw, single head stud or the cylinder pin of screw thread is opened in base wall.
Described square shell is the rectangular-shaped of hollow, more than 6 times of a length of described graphite bonded earth electrode diameter of described square shell.
The greatest diametrical dimension of described oval connecting hole is semicircle less than the summation of described graphite grounding body diameter, the upper end of described graphite grounding body, and the lower end of described graphite grounding body is square and in ramped shaped, and ramp angles is between 10～30 degree.
Described square shell wall thickness dimension is equal to 5mm.
Described square shell wall thickness dimension is more than 5mm.
Squash type lightning-proof grounding body connector described in the utility model provides the benefit that: simple structure, and material selection is easy to get, processing cost is low, additionally, employing continue part connect graphite cable grounding body there is easy construction, connect reliable, the advantages such as ageing resistace is good, recyclable.
