Description
Technical field
The utility model is related to a kind of electroscope.
Background technology
Electroscope is that whether a kind of detection object powered and instrument of rough estimate carried charge size.When examined object
During the conductor on contact electroscope top, on the paillon foil that the electric charge of itself institute's band can be passed in glass bell jar, due to like charges phase
Mutual to repel, paillon foil will be separated automatically, open angled, to be at an angle of according to two paillon foils big I estimation object carried charge
Size.
It is frequently necessary to use electroscope electrical verification in distribution ongoing operations, according to current electroscope, operating personnel are often
Run into following problem：
1st, existing electroscope is the straight contact of metal, and during electrical verification, the line facility to eminence carries out electrical verification, due to testing
Farther out, human eye is difficult to determine whether electrical verification probe contacts with line facility electrical distance human body, influences electrical verification accuracy；
2nd, it is necessary to metal probe is exerted oneself contact electrical verification position, once overexerting, will make electroscope during daily electrical verification
Expansion link is retracted, and is influenceed normal electrical verification, is caused electroscope to damage and electrical verification tip damage；
3rd, existing 10kV electroscopes generally have two kinds of length models of 1.2m, 4m, the minimum of overhead line conductor distance to the ground
Distance：The vertical range of dense population areas is 6.5m, and the vertical range of sparsely populated area is 5.5m, and existing electroscope length is very
Difficulty meet rise from overhead transmission line electrical verification.
Therefore, applicant feels the need to be improved existing electroscope.
Utility model content
The purpose of this utility model is for drawbacks described above of the prior art, there is provided one kind improves electrical verification effective percentage,
Expansion link retraction limited, and increasing length electroscope.
To realize above-mentioned utility model purpose, the utility model employs following technical scheme：A kind of electroscope, including gold
Category contact, plastic cap, some expansion links, and base；The metal contact is mutually threadedly coupled with the plastic cap, and
Metal contact includes metal half opening elbow and metal straight peen；The some expansion links are socketed successively, and every flexible
Bar is both provided with elastic card fastener；The base lower end inside is provided with internal thread.
Additionally, the utility model also provides following attached technical scheme：
The elastic card fastener includes flexure strip and ball button, and flexure strip is located in expansion link, in its one end and expansion link
Wall is fixedly connected, and the other end freely activity, ball button is fixedly connected with flexure strip, and is stretched out outside expansion link by an opening,
Abutted with adjacent expansion link.
Compared to prior art, advantage of the present utility model is：A kind of electroscope is disclosed, its simple structure is used
Convenient, metal contact includes metal half opening elbow and metal straight peen, elastic card fastener, and bottom is set up in expansion link
Seat lower end sets internal thread, it is achieved thereby that improving electrical verification efficiency and accuracy, expansion link retraction is limited, and increasing length is right
Strong facilitation is played in safe distribution of electric power production.

Specific embodiment
Technical solutions of the utility model are made with further nonrestrictive detailed below in conjunction with preferred embodiment and its accompanying drawing
Explanation.
See Fig. 1, electroscope of the present utility model includes metal contact 1, plastic cap 2, some expansion links 3, and base
4；Wherein, metal contact 1 is used to be electrically connected with overhead transmission line or other electrical equipments, and conduction is used；Plastic cap 2 is used for wrapping portion
Metal contact 1；Some expansion links 3 constitute the main part of electroscope, and its scalable connection each other, the used time stretches out, carries
Electroscope length is risen, not used time retraction, reduce space hold, the inside of some expansion links 3 can be additionally used in cabling；Base 4
For hand-held or external link rod.
See Fig. 2 and Fig. 3, metal contact 1 is mutually threadedly coupled with plastic cap 2, metal contact 1 includes metal half opening elbow
1a and metal straight peen 1b, therefore to high-tension overhead line electrical verification, can directly from the top down by metal half opening elbow 1a
Hang on overhead transmission line, it is ensured that effectively contact powered position；During to switch outlet and insulated circuit sensing electrical verification, metal is half-open
Mouth elbow 1a metal electrical verifications part can also directly wrap up circuit, increase induction area, it is ensured that effective electrical verification.
Some expansion links 3 are socketed successively, and every expansion link is both provided with elastic card fastener 5.See Fig. 4, elastic card
Fastener 5 includes flexure strip 5a and ball button 5b, flexure strip 5a in expansion link 3, and its one end is fixed with the inwall of expansion link 3 and connected
Connect, the other end freely activity, ball button 5b is fixedly connected with flexure strip 5a, and is stretched out outside expansion link 3 by an opening 7, with
Adjacent expansion link 3 abuts, the telescopic movable between limitation expansion link, but because flexure strip 5a has certain elastic force,
Therefore when ball button 5b is pressed with hand, ball button 5b and flexure strip 5a bounces back, and ball button 5b departs from against phase with expansion link 3
Expansion link even and retractable.The design of elastic card fastener 5 limits the telescopic movable between expansion link, it is to avoid exerted oneself
When violent, electroscope expansion link is retracted, and is influenceed normal electrical verification, is caused electroscope to damage and electrical verification tip damage.
The lower end inside of base 4 is provided with internal thread, therefore base 4 can be docked with external link rod screw thread, increases
Electrical verification length.
Comprehensive mentioned above, electroscope simple structure of the present utility model, expansion link retraction is limited, and length can
Increase, electrical verification efficiency and accuracy can be greatly improved, strong facilitation is played to safe distribution of electric power production.
It is pointed out that above-mentioned preferred embodiment is only explanation technology design of the present utility model and feature, its purpose
It is to allow person skilled in the art will appreciate that content of the present utility model and implement according to this, this reality can not be limited with this
With new protection domain.All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in this reality
Within new protection domain.
