Abstract
The utility model discloses a kind of battery group electric discharge attachment devices, including test lead and female mouth；The test lead is both-end rotary screw structure, and one end is for accessing direct-current discharge instrument, and the other end is for accessing female mouth；Described mother mouth one end is screw-rod structure, and the other end is Screw hole structure, and the screw hole of the screw-rod structure and battery group discharge connection plate matches, and is fixed by nut；The Screw hole structure is for accessing test lead；Mother's mouth further includes the insulating gum cover being sleeved on outside screw-rod structure and Screw hole structure, which is avoided that current direct current system discharge test line access battery group needs band to be electrically accessed, and there are security risks for operation maintenance personnel；And it is bad in the presence of fastening, cause contact resistance between conducting wire excessive, cause to generate heat, influences battery regular picture；With battery group wire connection interface may be damaged when screw to be dismantled, thus the problem of causing mechanical damage to the metal joint of battery and conducting wire.
Description
Technical field
The utility model relates to substation field, especially a kind of battery group electric discharge attachment device.
Background technique
Currently, it when direct current system maintenance personnel is to storage batteries of transformer substation group full capacity proof discharge, generally requires and first tears open
Lower battery group positive and negative end connecting line, then pass through discharge test line on battery group positive and negative electrode and connect DC load instrument.
This needs maintenance personnel's hot line job, has the risk of electric shock when disconnecting line, is easy to cause DC system grounding；Some batteries
It is spaced relatively closely between group positive and negative anodes, there is the risk for causing direct current system short circuit, seriously threaten the person and equipment safety.Meanwhile
It is longer due to tearing setting up time open, influence service work efficiency.Therefore need to design a set of new DC load instrument and battery group
Attachment device between positive and negative anodes accesses battery group discharge loop to achieve the effect that exempt to disconnect line for DC load instrument.
Utility model content
The utility model in view of the deficiencies of the prior art, proposes that one kind is avoided that the current most common direct current system electric discharge examination
Testing line access battery group needs band to be electrically accessed, and there are security risks for operation maintenance personnel；And it is bad in the presence of fastening, cause conducting wire indirect
Electric shock resistance is excessive, causes to generate heat, influences battery regular picture；Connect with battery group conducting wire may be damaged when screw to be dismantled
Connection interface, to cause the battery group electric discharge attachment device of mechanical damage to the metal joint of battery and conducting wire.
In order to realize above-mentioned purpose of utility model, the utility model the following technical schemes are provided:
A kind of battery group electric discharge attachment device, including test lead and female mouth；The test lead is that both-end is rotary
Screw-rod structure, intermediate to be connected by conducting wire, one end is for accessing direct-current discharge instrument, and the other end is for accessing female mouth；Mother's mouth
One end is screw-rod structure, and the other end is Screw hole structure, and the screw hole of the screw-rod structure and battery group discharge connection plate matches,
And it is fixed by nut；The Screw hole structure is for accessing test lead；Mother's mouth further includes being sleeved on screw-rod structure
With the insulation sleeve outside Screw hole structure.
Further, screw rod, the threaded bore portion of female mouth all use copper material, and the shell of the nut uses gum cover
It insulate.
Further, the test lead and female mouth shell, which can be, has preferably insulation energy by ceramics, north material, glass etc.
The material of power is made.
Further, the screw-rod structure of the test lead end includes rotary metal screw rod and edge gum cover.
Further, the screw-rod structure at the test lead both ends is identical.
Battery group electric discharge attachment device disclosed by the utility model has following technical effect that first, female mouth front end
Screw rod can be fixed on battery group electric discharge terminal plate by nut, until fixation, reduce contact resistance；
Second, the screw hole of female mouth rear end and the screw rod of electrical discharge wire match, and can be reduced contact resistance, solve heating problem；Third,
Wiring work before battery group is discharged is carried out, only electrical discharge wire need to be screwed in the mother having been attached on battery group discharge connection plate
Mouthful, without disconnecting battery group positive and negative electrode screw, wiring is simple, improves working efficiency；Four, this attachment device, test
Conducting wire (in addition to rotary screw part) and female mouth shell are insulation system, and without touching current-carrying part, raising connects wiring process
Line process safety.
Detailed description of the invention
