Abstract
The utility model relates to a Plug-in type three-phase cable current-testing short-circuit grounding device which is a tool applicable to the routine overhaul and the maintenance of urban distribution 10kV cable branch box. The plug-in type three-phase cable current-testing short-circuit grounding device comprises cable elbow heads; a lead wire is provided with threes cable elbow heads which are connected in parallel; and the other end of the lead wire is connected with a grounding connector. The plug-in type three-phase cable current-testing short-circuit grounding device is applicable to the 10kV cable branch box; during use, cable accessories or box body baffles are unnecessarily detached; the cable branch box can be detached only by using the special elbow head operating tool and safety protective equipment in hand without any damage to the cable accessories and other equipment, and the device is sealed and damp-proof; reliable current testing can be carried out on the 10kV cable safety and conveniently, thereby solving the problem that no special tool can be used to test the current of the prior cable branch box, and improving the working efficiency.
Description
Technical field
The utility model relates to a kind of maintenance repair of urban distribution network 10kV cable branch box and instrument of maintenance work of being applied to.
Background technology
In the maintenance repair and maintenance work of urban distribution network 10KV cable branch box in the past,, there is potential safety hazard because cable line all insulation and being closed in the structures such as underground pipe trench normally often is difficult to find electrical verification point and hangs earth connection when power failure work.
Summary of the invention
The purpose of this utility model is that a kind of plug-in threephase cable electrical verification short circuit earthing device that can find electrical verification point or hanging wire ground wire when power failure work easily will be provided.
The purpose of this utility model is achieved in that a kind of plug-in threephase cable electrical verification short circuit earthing device, comprises cable elbow head, is parallel with three cable elbow heads on the lead, and the lead other end is connected with grounding connector.
The plug-in threephase cable electrical verification short circuit earthing device that the utility model provides, the scope of application is extensive, and nearly all 10kV cable branch box can both be suitable for; Safe and reliable, do not need cable branch box to be dismantled with the method for dismantling electric cable accessories or casing baffle plate like that in the past, as long as existing private cable elbow head operation tool and safety protective tools just can be dismantled in the utilization hand, can not injure electric cable accessories and other equipment yet, and sealed damp-proof; Economical and practical, it cheap uses common material just can make; Can safe ready the 10KV cable is carried out reliable electrical verification, the case that has solved the prior cable branch does not have the problem that professional tool carries out electrical verification; The raising of operating efficiency; owing to there was not the earth connection of cable branch box special use in the past; can only seek the earth point that is fit to by spended time when on feeder pillar, working; carry out ground connection as earth connection being hung on cable branch box distribution transformer far away; owing to lack the special messenger guard; usually can go out meaning and destroy feeder pillar or the stolen incident of earth connection; use this device after as long as installing finishes; can also pin cable branch box; thereby dwindled the power failure scope to a certain extent; shorten interruption duration, improved operating efficiency.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable elbow head 1, is parallel with three cable elbow heads 1 on the lead 2, and the lead other end is connected with grounding connector 3.
Three cable elbow heads 1 are used for stube cable feeder pillar elbow head in the utility model, play interconnect function; During use, extract feeder pillar elbow head, will connect the plug-in threephase cable electrical verification short circuit earthing device insertion feeder pillar T head of ground connection again with the cable special operating tool with the cable special operating tool.If the feeder pillar cable has electricity, will send sound and light signal with the high voltage electroscope detection and represent that electricity is arranged, so just can the safe reliable ground connection of electrical verification.
