Abstract
The utility model relates to a special-purpose ground wire head for bus maintenance of a centrally installed cabinet. The ground wire head comprises a main body, a contact port for a static contact is opened at the top of the main body, the side wall of the main body is equipped with ground wire screws, the bottom of the main body is fixedly connected with a handle, a buckle is opened in the handle, and the handle is connected with an insulator spindle; and three spring pads are mounted in the contact port for the static contact. The special-purpose ground wire head for bus maintenance of the centrally installed cabinet has the advantages that an operation staff can independently complete grounding of a bus via the ground wire head, thereby reducing equipment maintenance time, and improving power supply reliability; and it is not required to open the back door of a bus PT cabinet during grounding of the bus, thereby standardizing safety arrangement on a maintenance site, and ensuring personal safety.
Description
Technical field
The utility model relates to a kind of earth connection point, relates in particular to a kind of middle-placed switch cabinet busbar overhaul Special grounding the end of a thread.
Background technology
At present, when 10kV middle-placed switch cabinet busbar overhaul, do not hang over 10kV bus PT cabinet bus static contact Special grounding the end of a thread, after just equipment has a power failure, after the Awaiting Overhaul personnel reach the spot, 10kV bus PT cabinet back door is opened directly attaching on bus.So on the one hand the meeting extension device repair time, reduce power supply reliability; Also can cause simultaneously the site safety measure lack of standardization.
Summary of the invention
The purpose of this utility model is to provide a kind of shortening overhaul of the equipments time, improves middle-placed switch cabinet busbar overhaul Special grounding the end of a thread of power supply reliability.
For achieving the above object, the technical scheme that adopts of the utility model is:
A kind of middle-placed switch cabinet busbar overhaul Special grounding the end of a thread, comprising: main body, its characteristics are: the top of described main body has the fixed contact contact opening, and the sidewall of main body is equipped with the earth connection screw, and the bottom of main body is fixedly connected with jug.
According to described middle-placed switch cabinet busbar overhaul Special grounding the end of a thread, its characteristics are: have buckle on described handle.
According to described middle-placed switch cabinet busbar overhaul Special grounding the end of a thread, its characteristics are: described handle is connected with insulating bar.
According to described middle-placed switch cabinet busbar overhaul Special grounding the end of a thread, its characteristics are: in described fixed contact contact opening, spring pad is installed, the quantity of spring pad is 3.
The utility model has the advantages that: use the utility model operations staff can complete alone busbar grounding work, reduce the overhaul of the equipments time, improve power supply reliability.Need not to open bus PT cabinet back door during busbar grounding, standard Overhaul site safety measure is arranged, guarantees personnel's personal safety.
