Abstract
The utility model relates to a kind of transformer substation grounding wire common ground end, comprises earth terminal main body, and described earth terminal main body comprises clamp and earth electrode; Described clamp comprises base plate and pressing plate, and base plate respectively establishes a groove fit to become clamp passage with pressing plate mesophase spherule correspondence position, is equipped with two bolts hole in the groove both sides of base plate and pressing plate along groove length direction; Described earth electrode is connected with base plate, comprises band iron formula earth electrode and bolt type earth electrode.The utility model solve earth connection specification and each Substation Station five-prevention locking system incompatible and cause the uncurrent difficult problem of earth connection, meet the requirement of safety in production, reduce the labour intensity of operating personnel, reduce O&M cost.By technological improvement, decrease the value volume and range of product that operating personnel carry earth connection, reduce business capital cost.
Description
Technical field
The utility model relates to a kind of substation grounding end, is specifically related to a kind of transformer substation grounding wire common ground end.
Background technology
Earth connection installed by the converting equipment of maintenance, and be the basic measures ensureing maintainer's personal safety, the installing quality of earth connection is directly connected to the protection level to maintainer.At present, transformer station is all furnished with the earth connection of some, because the five-prevention locking system of each transformer station is not identical, when the five-prevention locking system of earth connection specification and transformer station is incompatible, just cannot effectively use.Often operating personnel will carry with car and overlap earth connection more, sometimes due to carelessness cause carry earth connection and transformer station five-defence block device not to the time in of corresponding operating personnel's reciprocating operation team guard station is also needed to exchange, cause maintenance can not go into operation or cause the phenomenons such as maintenance scheduling time-out according to schedule, bring huge labour intensity and difficulty to operating personnel.
Summary of the invention
For the problems referred to above, the utility model, in conjunction with the earth terminal feature of multistation, provides a kind of transformer substation grounding wire common ground end.
For solving the problem, the technical scheme that the utility model is taked is: a kind of transformer substation grounding wire common ground end, comprise earth terminal main body, described earth terminal main body comprises clamp and earth electrode, described clamp comprises base plate and pressing plate, base plate respectively establishes a groove fit to become clamp passage with pressing plate mesophase spherule correspondence position, and described earth electrode comprises band iron formula earth electrode and bolt type earth electrode, is connected respectively with base plate.Described base plate and pressing plate measure-alike, be equipped with two bolts hole in the groove both sides of base plate and pressing plate along groove length direction, be used for construction bolt fixed base plate and pressing plate.Use procedure center platen covers clamp passage earth connection being put into base plate and pressing plate formation on base plate, and clamps by bolt being penetrated four bolts hole.
Described band iron formula earth electrode comprises the through hole coordinated with five-defence block device of ground plate and ground plate end.Band iron formula earth electrode is undertaken coordinating realizing effective grounding by through hole and five-defence block device.
Described bolt type earth electrode comprises screw rod, be through at the nut of screw rod and the screw end head hanging hole for padlock.Bolt type earth electrode passes the through hole of ground stud by screw rod and compresses with nut, finally at hanging hole place padlock.
Described clamp and band iron formula earth electrode, bolt type earth electrode are Y type, and the angle of clamp and band iron formula earth electrode, bolt type earth electrode is 120 degree.Clamp and band iron formula earth electrode, bolt type earth electrode are the five-defence block device that Y type is applicable to arbitrary model, the angle of clamp and band iron formula earth electrode, bolt type earth electrode be 120 degree be convenient to equipment ground end with the use of, may occur if be less than in 120 degree of use procedures earth connection with earth terminal in conjunction with unstable situation.
Because TC has good thermal conductivity and conductivity, described earth terminal main body adopts TC to make.
The utility model solve earth connection specification and each Substation Station five-prevention locking system incompatible and cause the uncurrent difficult problem of earth connection, meet the requirement of safety in production, reduce the labour intensity of operating personnel, reduce O&M cost.By technological improvement, decrease the value volume and range of product that operating personnel carry earth connection, reduce business capital cost.
