Description
Technical field
The utility model belongs to the special-purpose tool of a kind of cable branch box earth connection.
Background technology
The maintenance cable branch box is a very dangerous job, when breaking down, safety for the maintainer, usually the method that adopts is outage or has a power failure, make the cable branch box outage with convenient maintenance, but this method is very dangerous, non insurance, if send a telegram here suddenly when interruption maintenance, along separate routes incoming call or other people misoperation cause power connection, will inevitably cause staff's injures and deaths.When simultaneously, the electric weight that is stored in the remnants in the entire circuit overhauls the staff also is a kind of fatal harm.And the maintenance cable branch box extremely bothers, numerous rope, be generally assurance safety, earlier the European cable end in the cable branch box is used lead ground connection before the maintenance, operating procedure is the Jiao Gai on the joint sealing of opening earlier on the European cable end, the plug screw that again shutoff insulated is backed out, then will draw electric lead and be connected with European cable end inside groove, above-mentioned steps is the people and operates by hand, does not have the special isolation instrument.In the manual operating process of people, life security that can not the safeguard work personnel, electric shock injures and deaths incident happens occasionally.Serious threat operating personnel's life security.
Summary of the invention
The purpose of this utility model is the special-purpose tool of a kind of cable branch box earth connection of design, make to operate under the state of insulation and carry out, can safeguard work personnel's life security, the injures and deaths incident of stopping to shock by electricity, have safe and reliable, simple to operation, be convenient to the advantage that operating personnel carry.For this reason, the utility model mainly is made up of porcelain knob removal rod and cable end earth connection, the porcelain knob removal rod is made up of electro-insulating rubber handle, insulating bar and operating head, insulating bar one end is arranged with the electro-insulating rubber handle, the insulating bar other end is provided with operating head, and the operating head front end is provided with for the attachment plug inserting groove that insert or that supply the demolition nut to insert that draws on the electric lead; The cable end earth connection is formed by drawing electric lead, cable concentrator and ground connection copper sheet, the ground connection copper sheet connects and draws electric lead, draw being provided with of electric lead front end and draw electric sheet, drawing electric sheet upper end vertically is provided with and draws plug, the inserting groove that draws the first end correspondence of electric mortiser is provided with attachment plug, and the European cable end groove that draws plug other end correspondence is provided with and draws plug.The said structure design has reached the purpose of this utility model.
The utility model has the advantages that to make to operate under the state of insulation and carry out, can safeguard work personnel's life security, the injures and deaths incident of stopping to shock by electricity, have safe and reliable, simple to operation, be convenient to the advantage that operating personnel carry.

Embodiment
As shown in Figure 1, the special-purpose tool of a kind of cable branch box earth connection, main porcelain knob removal rod and cable end earth connection are formed.The porcelain knob removal rod is made up of electro-insulating rubber handle 8, insulating bar 9 and operating head 10.Insulating bar one end is arranged with the electro-insulating rubber handle, and the insulating bar other end is provided with operating head.The operating head front end is provided with for the inserting groove 11 attachment plug 12 insertions or that supply demolition nut 5 to insert that draws on the electric lead 2.
The cable end earth connection is formed by drawing electric lead, cable concentrator 3 and ground connection copper sheet 4, and the ground connection copper sheet connects and to draw electric lead, draws being provided with of electric lead front end and draws electric sheet 13, draws electric sheet upper end and vertically is provided with and draws plug.The inserting groove that draws the first end correspondence of electric mortiser is provided with attachment plug, and the European cable end groove that draws plug other end correspondence is provided with and draws plug 1.Be handled easily ground connection, can the European cable end of corresponding three-phase establish three and draw electric lead, and make three to draw the electric lead collection and be one and be connected with the ground connection copper sheet again after drawing electric lead with cable concentrator.
Laterally be provided with hand lever hole 7 on the insulating bar of described electro-insulating rubber handle one end, hand lever 6 penetrates in the hand lever hole.
During use, open the Jiao Gai that takes on the joint sealing on the European cable end earlier with the grappling fixture on the ground connection hook stick (for oneself has patent) of preparation earlier, in the inserting groove that the demolition nut is inserted, hand lever inserts in the hand lever hole again, with the demolition nut shutoff plug screw that insulate is backed out, then unloaded the demolition nut.The plug that draws that will draw on the electric lead after will respectively drawing in the attachment plug insertion inserting groove on the electric lead more one by one is connected with each European cable end inside groove one by one.Finish and draw the electricity operation.
As shown in Figure 2, the demolition nut that the plug screw that obviously shutoff insulated is backed out can be established one in addition and twist bar, establishes horizontal hand lever as twisting bar 14 1 ends in insulation, and the other end is established the operating head 16 that band connects slot 15.Result of use is identical, so be not repeated.
In a word, the utility model makes to operate under the state of insulation and carries out, can safeguard work personnel's life security, the injures and deaths incident of stopping to shock by electricity, have safe and reliable, simple to operation, be convenient to the advantage that operating personnel carry.Can promote the use of.
