Description
Technical field
The present invention relates to a kind of electroscope, more particularly, to a kind of contact AC high-voltage electroscope and its application.
Background technology
Contact high voltage electroscope is widely used in a variety of applications in transformer station, and it can judge to stand interior metallic conductor, aerial
Whether the equipment such as circuit, joint are powered, are the main tools that operations staff uses in work of transformer substation.Generally, transporting
Before administrative staff turns inspecting state to power failure equipments, equipment first is identified without electricity using electroscope, then hanging earthing conductor or closes ground connection lock
Knife, to ensure equipment and personal safety.During contact high voltage electroscope, if equipment is tested without electricity, without any signal, if having
Electricity, then send alarm.In order to exclude to cause because of electroscope failure itself to test the situation for having electric equipment still no alarm, using
Before such a electroscope, the testing button of itself can be used, ensures that electroscope circuit is working properly, then when to equipment electrical verification, abide by
The rule of " having-nothing-to have " is followed, all needs to test have electric equipment before and after electroless apparatus is tested, it is ensured that electroscope is working properly.But
It is that this electroscope has segmental defect, such as：During by testing button, not comprising metal probe, if metal probe and joint are deposited
It can not be checked in the problems such as fracture；Although according to the rule of " thering is-nothing-to have ", complex steps during electrical verification, and it can not exclude again
Dirt when testing no electricity, between metal probe and testee be present and the hidden danger of erroneous judgement be present.Have when being tested nothing around equipment with this
During the charging equipment of identical voltage class, the step of " having-nothing-to have " also is difficult to follow.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of exchange of contact is high
Electroscope and its application are pressed, the test department of original AC high-voltage electroscope has been allocated as related improvement, is reducing electrical verification step
Meanwhile it also add the accuracy of electrical verification.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of contact AC high-voltage electroscope, it is characterised in that including：
Insulating bar；
Telescoping mechanism, one end are connected with insulating bar；
Primary probe, it is connected with the telescoping mechanism other end；
Assist probes, it is connected with the telescoping mechanism other end；
Internal work loop, it is connected on insulating bar, and with primary probe and assist probes.
Described primary probe is the probe for possessing independent electrical verification.
After described telescoping mechanism action, turn on internal pull-up circuit, make assist probes, tested equipment metal part,
Primary probe, internal pull-up circuit form electrical circuit inspection.
Described telescoping mechanism is the telescoping mechanism with spring.
A kind of application of contact AC high-voltage electroscope, it is characterised in that including：
1) when needing electrical verification, primary probe and cooperating contact equipment under test, primary probe have possessed electroscope function, internal work
Circuit does not turn on simultaneously；
If 2) being tested equipment has electricity, electric alarm information has directly been sent, has otherwise performed step 3)；
3) top telescoping mechanism action, connects internal pull-up circuit, and electric current by assist probes, is tested from inside
Equipment metal part, primary probe, internal pull-up circuit form test loop, if test loop is working properly, probe not damaged, tests
Electrical equipment and tested between equipment without dirt, then send alarm signal, to show that the electroless state tested out before this is correctly effective.
Described electroscope can interpolate that electroscope and tested equipment room with the presence or absence of dirt, whether loose contact, metal
Situation of the probe with the presence or absence of fracture.
Compared with prior art, the present invention has advantages below：
1) it is simple to operate, original AC high-voltage electroscope is improved, is allowed to using simplification, safe.
2) accuracy is high, without individually being tested before electrical verification；Can ensure that tested equipment without electricity while, while also can
Judge whether electroscope is working properly；The electrical verification pattern of " having-nothing-to have " is without following it is ensured that the standard of electrical verification result
Really.
4) electrical verification efficiency is substantially increased, while improves the accuracy of electrical verification, safety guarantee is improved for electrical verification personnel.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in figure 1, a kind of contact AC high-voltage electroscope, including：Insulating bar 1；Telescoping mechanism 2, one end and insulation
Bar connects；Primary probe 3, it is connected with the telescoping mechanism other end；Assist probes 4, it is connected with the telescoping mechanism other end；Internal work returns
Road, it is connected on insulating bar, and with primary probe and assist probes.
Described primary probe 3 is the probe for possessing independent electrical verification.After described telescoping mechanism 2 acts, make internal work electric
Road turns on, and makes assist probes 4, is tested the metal part of equipment 5, primary probe 3, internal pull-up circuit formation electrical circuit inspection.Described
Telescoping mechanism is the telescoping mechanism with spring.
The application of contact AC high-voltage electroscope of the present invention, including：
1) when needing electrical verification, primary probe and cooperating contact equipment under test, primary probe have possessed electroscope function, internal work
Circuit does not turn on simultaneously；
If 2) being tested equipment has electricity, electric alarm information has directly been sent, has otherwise performed step 3)；If now electroscope without
Any signal is sent, then a kind of situation be tested equipment without electric, another situation be electroscope damage or equipment and electroscope
Dirt between probe be present causes loose contact.
3) top telescoping mechanism action, connects internal pull-up circuit, and electric current by assist probes, is tested from inside
Equipment metal part, primary probe, internal pull-up circuit form test loop, if test loop is working properly, probe not damaged, tests
Electrical equipment and tested between equipment without dirt, then send alarm signal, to show that the electroless state tested out before this is correctly effective.
