Description
Technical field
The utility model relates to power system power supply instrument, the multilayer line earth connection particularly a kind ofly stopping that power transmission carries out overhauling, use in cleaning works.
Background technology
As everyone knows, 400V distribution line is because former wire diameter is comparatively thin and design concept, the part distribution line number of plies is more, great Tai district can reach 7-9 floor, this just hangs earth connection to line outage and causes very large difficulty, considerable muscle power suspension earth connection can be expended for the operating personnel on shaft tower, be unfavorable for follow-up service work, and every sandwich circuit all hangs one group of earth connection in the past, a few sandwich circuit just needs to hang which floor earth connection, do not utilize construction, earth connection is hung for 6 sandwich circuits, 6 layers of earth connection are hung, need the time of about 1 hours, and power transmission extracts earth connection, also the time of about 1 hour is needed, this just causes the time shorten of middle work, extend interruption duration, the operating efficiency of electrician is reduced, also reduce power supply reliability simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the time that a kind of operating efficiency is high, reduce suspension earth connection, the multilayer line earth connection of operating time in the middle of increasing.
A kind of multilayer line earth connection, comprise insulating bar, clamp for ground wire and earth connection, it is characterized in that insulating bar is made up of insulating sleeve and insulating telescopic bar, insulating telescopic bar cover has spring and is inserted by insulating sleeve front end, insulating telescopic rod rear end portion is connected with the rear end of spring, insulating sleeve front end is provided with the block of tape insulation expansion link perforation, block is connected with insulating sleeve through screw thread, block realizes the connection of insulating telescopic bar and insulating sleeve, the rear end of insulating sleeve is provided with operating handle, first clamp for ground wire is connected with insulating telescopic bar front end through anchor ear, second clamp for ground wire is connected with the front end of insulating sleeve through anchor ear, Open Side Down for first clamp for ground wire, the opening upwards of the second clamp for ground wire, earth connection is through connecting bolt, anchor ear is connected with the second clamp for ground wire with the first clamp for ground wire.
The utility model can be provided with the 3rd clamp for ground wire, and the 3rd clamp for ground wire is spaced apart and arranged on insulating telescopic bar through anchor ear and the first clamp for ground wire, and earth connection is connected with the 3rd clamp for ground wire through connecting bolt, anchor ear.
The utility model can be provided with the 4th clamp for ground wire, and the 4th clamp for ground wire is spaced apart and arranged on insulating sleeve through anchor ear and the second clamp for ground wire, and earth connection is connected with the 4th clamp for ground wire through connecting bolt, anchor ear.
When the utility model uses, insulating telescopic bar can stretch according to the spacing of two wires, first clamp for ground wire, the second clamp for ground wire are hung on different wires, to reduce the quantity of earth brace, there is simple to operate, easy to use, operating efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in the figure, a kind of multilayer line earth connection, comprise insulating bar, clamp for ground wire and earth connection, it is characterized in that insulating bar is made up of insulating sleeve 1 and insulating telescopic bar 2, insulating telescopic bar 2 cover has spring and is inserted by insulating sleeve 1 front end, insulating telescopic bar 2 rearward end is connected with the rear end of spring, insulating sleeve 2 front end is provided with the block 3 of tape insulation expansion link perforation, block 3 is connected with insulating sleeve 1 through screw thread, block 3 realizes the connection of insulating telescopic bar 2 and insulating sleeve 1, the rear end of insulating sleeve 1 is provided with operating handle, the structure of above-mentioned each part and the interconnected relationship between them same as the prior art, this does not repeat, first clamp for ground wire 4 is connected with insulating telescopic bar 2 front end through anchor ear 5, second clamp for ground wire 6 is connected through the front end of anchor ear 7 with insulating sleeve 1, Open Side Down for first clamp for ground wire 4, the opening upwards of the second clamp for ground wire 6, earth connection 8 is through connecting bolt, anchor ear is connected with the second clamp for ground wire 6 with the first clamp for ground wire 4, earth connection 8 can be a wire, also can arrange respectively, the utility model can be provided with the 3rd clamp for ground wire, 3rd clamp for ground wire is spaced apart and arranged on insulating telescopic bar through anchor ear and the first clamp for ground wire.Earth connection is connected with the second clamp for ground wire with the first clamp for ground wire through connecting bolt, anchor ear.Can also be provided with the 4th clamp for ground wire, the 4th clamp for ground wire is spaced apart and arranged on insulating sleeve through anchor ear and the second clamp for ground wire.Earth connection is connected with the second clamp for ground wire with the first clamp for ground wire through connecting bolt, anchor ear.When the utility model uses, insulating telescopic bar can stretch according to the spacing of two wires, first clamp for ground wire, the second clamp for ground wire are hung on different wires, to reduce the quantity of earth brace, there is simple to operate, easy to use, operating efficiency advantages of higher.
