Description
Technical field
A kind of earthing or grounding means is the utility model is related to, especially a kind of transformer station's dead earth device.
Background technology
GIS combination electric appliance ground connection traditional method is to be connected to Equipment Foundations by underground grounded screen welding zinc-coated flat steel sheet ground wire
Channel-section steel, then be all connected without single earth point, the ground connection of GIS combination electric appliance package unit by basic channel-section steel with earth mat, by
Comprising combined electrical apparatuses such as disconnecting link, grounding switch, switch, current transformer, arresters in GIS combination electric appliance, different from general
Single electrical equipment can be connected to be grounded by basic channel-section steel with earth mat.The ground connection of grounding switch, arrester in GIS combination electric appliance
Dash current is very big, and ground connection is all connected by basic channel-section steel with earth mat, once breaking down directly makes whole GIS combinations electricity
Device all burns, tripped, having a power failure and cause immeasurable loss.
Utility model content
Technical assignment of the present utility model is to be directed to above the deficiencies in the prior art, and provides a kind of transformer station and connect with fixation
Ground device.
Technical scheme is used by the utility model solves its technical problem：A kind of transformer station dead earth device,
Including Electric Appliance Cabinet, wherein being provided with some ground terminals in the outside of the Electric Appliance Cabinet, set on the ground of the Electric Appliance Cabinet side
There is earthing block, the earthing block is connected by wire with the ground terminal.
Further improve：The earthing block includes support block and cover plate, and the cover plate is connected by bolt with support block,
Perforation is provided between the support block and cover plate, one end of the wire is located in the perforation.
Further improve：Extended interface is provided with the earthing block.
Further improve：Ground wire is provided with the bottom of the earthing block.
The advantages of the utility model：The ground terminal being arranged on outside Electric Appliance Cabinet, with the disconnecting link in Electric Appliance Cabinet, earthing
The electrical equipment such as lock, switch, current transformer, arrester connect one to one, and so when some electrical equipment leaks electricity, electric current is just
The earth can be directly induced current into by ground terminal, so as to avoid the excessive situation for burning other electrical equipment of electric current.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the structural representation of the utility model earthing block.
Embodiment
The utility model is described below with reference to Figure of description.
As illustrated, a kind of transformer station dead earth device, including Electric Appliance Cabinet 1, wherein in the outside of the Electric Appliance Cabinet 1
Provided with some ground terminals 2, be provided with earthing block 4 on the ground of the side of Electric Appliance Cabinet 1, the earthing block 4 by wire 3 with
The ground terminal 2 connects；Earthing block bag 4 includes support block 41 and cover plate 42, and the cover plate 42 passes through bolt 44 and support block 41
Connection, perforation 43 is provided between the support block 41 and cover plate 42, one end of the wire 3 is in the perforation 43；
The earthing block 4 is provided with extended interface 6；Ground wire 5 is provided with the bottom of the earthing block 4.
Its operation principle is：In use, when drain conditions occurs in some electrical equipment in Electric Appliance Cabinet 1, electric current leads to
Ground terminal 2, wire 3 and earthing block 4 are crossed, induces current into the earth, so as to avoid the situation that heavy current burns electrical equipment, when
It when there be other electrical equipment on the side of Electric Appliance Cabinet 1, can be connected with the extended interface 6 on earthing block 4, can meet to leak other electrical equipment
Electric protection.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
