The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part and provides a kind of method of earth potential working that adopts that loosening device clamp is carried out charged fastening substation equipment bolt tightener.
The purpose of this utility model is achieved through the following technical solutions:
A kind of substation equipment bolt tightener, its structural feature is: comprise insulating bar, universal joint, the universal joint of described universal joint for being connected with the bolted sleeve, universal joint is arranged at an end of insulating bar, and described insulating bar is an insulating driving rod.
An end setting of common insulating bar can with the bolted sleeve universal joint of wildcard mutually, because the compatibility of universal joint, therefore can change the bolted sleeve according to the bolt model easily, and can wear when being out of line at insulating bar and bolt and adjust angle, guarantee that fastening operation is normal by universal joint.Therefore adopt bolt tightener of the present utility model, just need not to adopt the equipotential live line work method like that to prior art, must directly contact with electrical body, increased staff's workload, also brought security threat, such as might operating personnel's scald etc. seriously taking place because of the heating of bolt node to the staff.And can stand directly on ground or the framework, transport out of electrical body work.
The other end in insulating driving rod is provided with jockey, and described jockey can be connected with another insulating driving rod.
End in insulating driving rod is provided with this jockey, just can random as required flexibly lengthening insulating driving rod, thus make this bolt tightener be applicable to more conditions.
Described jockey or be the used general bayonet joint of common insulating bar.
Described jockey can also be the connector that is provided with nipple at two ends, and common insulating bar is provided with the screw connection that connector therewith matches.
Described insulating driving rod is that fiber glass epoxy draws tube pulling.
Described substation equipment bolt tightener also includes the thorn wheel spanner, adopts the general bayonet joint of insulating bar to be connected between thorn wheel spanner and the insulating bar.
At the other end of insulating bar the thorn wheel spanner is set, connects by bayonet joint between the two, like this, just can in good time as required assembling, to be suitable for the bolts assemblies of multiple different angles.
Be rotating flexible connection between described thorn wheel spanner and the bayonet joint.
To sting and adopt rotating flexible connection between wheel spanner and the bayonet joint, and so just can make the thorn wheel spanner realize relatively rotating, can carry out the front and back push-and-pull again, screw or unscrew nut thereby make this fastener can realize rotating with respect to bayonet joint.
Rotation between described thorn wheel spanner and the bayonet joint is that 360 degree rotate.
Flexible connection between thorn wheel spanner and the bayonet joint is for to be connected by connector, stings that wheel spanner is rotating to be connected on the connector, and bayonet joint is rotating to be connected on the connector.
Described connector is a panel with connecting elements.
Bolted sleeve at bolt tightener is embedded with alnico magnets.
Bolted sleeve at bolt tightener is embedded in alnico magnets, can utilize the suction realization bolt of magnet, the dismounting or the installation of nut.
Advantage of the present utility model is:
Converting equipment cable clip bolt fastener of the present utility model, to vertically wear on the electrical equipment to and level wear to bolt all can carry out fastening easily, both can fastening disconnecting link etc. the connecting bolt of ground installation, the bolt that also can fastening high-altitude median generatrix node and the bolt of power transmission sequence drainage thread node, it is comparatively convenient to operate, and can reach re-set target substantially.The utility model also has simultaneously:
1. charged in the past fastening apparatus heating bolt must be installed instruments such as insulated flexible ladder, hard ladder for adopting equipotential live line work during operation, need 1 of equipotential live line work electrician, cooperates 4 of electricians, and finishing a setting needs 40-50 minute.Use the charged fastener operation of converting equipment cable clip bolt, only need 2 of earth potential working personnel, finish a setting and need 10-20 minute.
2. safe: use the equipotential live line work method, must directly contact with electrical body, the converting equipment clearance is less, and safe distance be cannot say for sure card, when equipment bolt node generate heat when serious the operating personnel have scald dangerous.Use the charged fastener operation of converting equipment cable clip bolt, stand directly on ground or framework when the operating personnel operates,, be not subjected to the constraint of equipment clearance substantially away from electrical body, safer reliable.
