Abstract

The utility model discloses an insulation rod test wire connector, comprising an insulation sleeve, a test wire inserting cylinder, a connection rod, a wire-guiding slot, a conductive sleeve, a lead and a lead slot. The test wire inserting cylinder is fixedly mounted on the upper part of the insulation sleeve in a radial manner; a conductive sleeve is positioned coaxially within the test wire inserting cylinder; a connection rod is fixedly installed under the test wire inserting cylinder; a lead is installed within the connection rod; an the semiarc-shaped wire-guiding slot connected to the lead wire of a lighting rod is fixedly installed under the connection rod; the semiarc-shaped lead slot is fixedly installed within at the inner side of the lead wire slot; the conductive sleeve communicates with the lead slot through the lead; and an axial straight slot is arranged under the lead wire slot and on the lower part of the insulation sleeve. The insulation rod test wire connector employs the reliably fixed sleeve to connect the test wire so as to enhance effective electric contact between the test wire and the lead wire on the upper end of the lighting rod. Besides, the insulation rod test wire connector can guarantee reliable connection and fixation between the insulation rod and the test wire. The insulation rod test wire connector is standard and simple in operation and guarantees safety of people and equipment.

Description

Insulating bar test electric wire connecting junction
Technical field
The utility model belongs to the substation equipment maintenance and repair field, relates to transformer station's repair based on condition of component routine testing equipment, especially a kind of insulating bar test electric wire connecting junction.
Background technology
In the charged detection of zinc oxide lightning arrester block property current, p-wire need be connected to obtain current signal with arrester discharge counter upper end lead-in wire.The method that extensively adopts is at present, and p-wire is fixed on the insulating bar with wire clamp, then insulating bar is hung on the lead-in wire of arrester discharge counter upper end, thereby tests.This method operation is comparatively simple, but because test clamp is firm inadequately with being connected of insulating bar, there is the hidden danger that comes off, after if p-wire comes off, mistake is bumped on the lead of receiving adjacent phase, may cause phase fault, causes the damage of grid equipment and testing tool, and then threaten the stable operation of system, even also can cause major accidents such as personal injury.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of simple in structure, reasonable in design, easy to use, solid and reliable insulating bar test electric wire connecting junction is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of insulating bar test electric wire connecting junction, it is characterized in that: comprise insulating sleeve, the slotting tube of p-wire, connecting rod, lead-in wire groove, conductive casings, lead and metallic channel, insulating sleeve top one side radially is fixed with a p-wire and inserts tube, and this p-wire is inserted the interior coaxial package of tube a conductive casings; This p-wire is inserted the tube lower end and is fixed with a connecting rod, and lead is installed in the connecting rod; Be fixed with the lead-in wire groove of half arc that is connected with the lightning rod lead-in wire in the connecting rod lower end, this lead-in wire groove inboard is fixed with the metallic channel of half arc, and above-mentioned conductive casings is communicated with by lead with metallic channel, and the insulating sleeve bottom of lead-in wire groove below is shaped on an axial groove.
And the insulating sleeve outer wall of described groove one side is hinged with a buckle that prevents wire dropping.
And described insulating sleeve, p-wire are inserted tube, lead connecting rod and lead-in wire groove and are all adopted the insulating material injection mo(u)lding.
Advantage of the present utility model and good effect are:
1, this electric wire connecting junction can strengthen p-wire and effective electric contact of lightning arrester upper end lead-in wire.
2, this electric wire connecting junction can guarantee that insulating bar is connected reliably with p-wire and fixes, and eliminates safe hidden trouble.
3, the utility model intends adopting the sleeve pipe of secure fixation that p-wire is connected, can strengthen p-wire and effective electric contact of lightning arrester upper end lead-in wire, and can guarantee that insulating bar and p-wire are cocksure is connected and fixes, make and operate that standard is easy more, key is the safety that can guarantee the person and equipment.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of insulating bar test electric wire connecting junction, comprise that insulating sleeve 4, p-wire are inserted tube 1, connecting rod 2, groove 3, conductive casings 6, lead 9 and metallic channel 7 go between, insulating sleeve top one side radially is fixed with a p-wire and inserts tube, and this p-wire is inserted the interior coaxial package of tube a conductive casings; This p-wire is inserted the tube lower end and is fixed with a connecting rod, and lead is installed in the connecting rod; Be fixed with the lead-in wire groove of half arc that is connected with the lightning rod lead-in wire in the connecting rod lower end, this lead-in wire groove inboard is fixed with the metallic channel of half arc, and above-mentioned conductive casings is communicated with by lead with metallic channel.
Insulating bar and lead are installed for convenience, and the insulating sleeve bottom of lead-in wire groove below is shaped on an axial groove 8, and the insulating sleeve outer wall of this groove one side is hinged with a buckle 5 that prevents wire dropping.
Above-mentioned insulating sleeve, p-wire are inserted tube, lead connecting rod and lead-in wire groove and are all adopted the insulating material injection mo(u)lding, prevent short circuit, effectively guarantee test safety.
When carrying out test experiments lead 10 is inlaid in the metallic channel, the described buckle of snapping prevents that lead from deviating from from the groove of insulating sleeve, p-wire is inserted in the conductive casings, and p-wire to be tested is communicated with by lead with lead.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
