Description
Technical Field
The utility model belongs to the technical field of arrester controlling means and specifically relates to a arrester earth connection controlling means that opens and shuts is related to.
Background
The lightning arrester is an electrical device which can release the energy of thunder and lightning or the overvoltage of the operation of electrical equipment, protect the electrical equipment from the damage of instantaneous overvoltage, and can cut off follow current without causing the short circuit of the system ground. When the protected equipment operates under normal working voltage, the lightning arrester can not act and is regarded as open circuit for the ground, once high voltage occurs and the insulation of the protected equipment is endangered, the lightning arrester acts immediately to guide high-voltage impact current to the ground, so that the voltage amplitude is limited, and the electrical equipment is protected; when the overvoltage disappears, the lightning arrester can restore to the original state rapidly, so that the system can supply power normally.
The ground wire at the tail end of the lightning arrester is generally grounded and fastened by a common bolt, the lightning arrester cannot realize online monitoring when an online monitor is not installed, and the lightning arrester cannot be installed again after being detached and detected after power failure. Because the arrester is located inside looped netowrk cabinet, the cubical switchboard, and the space is narrow and small, very inconvenient and consuming time when leading to the operation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned technical problem, provide a lightning arrester earth connection controlling means that opens and shuts. The method is mainly realized by the following technical scheme:
the utility model provides a lightning arrester earth connection controlling means that opens and shuts, its characterized in that includes an insulating frame and sets up the electrically conductive nut pole on the insulating frame, electrically conductive nut pole below is provided with electrically conductive switching subassembly, electrically conductive switching subassembly one end can contact or the disconnection with the one end of electrically conductive nut pole, and the other end passes through ground wire fixation nut to be fixed on the insulating frame.
In the above ground wire opening and closing control device for the lightning arrester, the conductive opening and closing assembly comprises a spring assembly, one end of the spring assembly is fixed with a copper sheet, the copper sheet can be in contact with or disconnected from one end of the conductive nut rod under the action of the spring assembly, and the other end of the spring assembly is fixed on the insulating frame through a fixing nut.
In the above ground wire opening and closing control device for the lightning arrester, the spring assembly comprises at least two torsion springs, one end of each torsion spring is fixed on the insulating frame, and the other end of each torsion spring is fixed on the copper sheet.
Therefore, the utility model has the advantages of as follows: 1. the opening and closing operation of the grounding wire of the lightning arrester is simple and convenient; 2. The operation is safe and reliable; 3. the maintenance is convenient.
