Description
Technical field
The present invention relates to a kind of detection type tester ground wires.
Background technology
The reliable ground of electrical equipment, is one of technical measures that production scene ensures safety, and main purpose is protection people
The safety of body and equipment.When the electrical equipment electric leakage of metal shell or during internal fault, ground wire can prevent its to it is artificial into
Injury.
In daily electrical test work, test apparatus is the essential work implement of work.Test apparatus is often all
Can be furnished with a ground wire, connect instrument and earthing or grounding means.The ground stud that the ground wire grounded end of test apparatus is clamped be often accompanied by lacquer painting or
The blocked up oxide layer of person, like this ground wire can not reliable ground, can not play the role of being effectively protected instrument.High pressure is tried
It tests and often generates high voltage, if the loose contact of instrument ground wire is good, be both possible to burn instrument during experiment, also having can
The danger that the person gets an electric shock can occur.For example, during circuit electromotive checking is carried out, if ground connection line loop is obstructed, can cause
Residual charge when electric discharge, electricity hinder operating personnel；For another example, carry out in leakage current of an arrester test process, if ground
Line loop is obstructed, and the metal shell of test apparatus has induced electricity, be easy to cause personnel's electric shock.
In State Grid Corporation of China's electric power safety working regulation power transformation part, 14.1.4 and 14.2.6 clear stipulaties：Metal
The instrument and transformer case of shell should be grounded；The metal shell of experimental rig answers reliable ground.However, it is given birth in actual production
During work, due to objective and subjective reason, often ignore the importance of ground wire.At present, scene is combined frequently with conducting wire with clip
Method, clip is clipped in reserved ground stud（Pole）On, have flexibility good, special equipment is not required, working site is easily real
The advantages that existing, but shortcoming does not possess self-checking function, exists to a certain degree it is also obvious that can not such as judge whether reliable ground
Security risk.
The content of the invention
The object of the present invention is to provide a kind of detection type tester ground wires with sound-light alarm prompt facility, pass through sound
Light alarm is good to represent ground wire contact.
To achieve these goals, the technical solution that the present invention takes is as follows：
A kind of detection type tester ground wire, including ground wire, detection line, wire connection terminal, detection module and earthing clamp；
The ground wire is connected between wire connection terminal and a clamping plate of earthing clamp, and the detection line is connected to wire connection terminal
Between another clamping plate of earthing clamp；
The detection module includes being sequentially connected in series DC power supply, detection switch and warning device in detection line；
The warning device includes the buzzer being connected in detection line and the LED light being connected in parallel on buzzer.
As a further improvement on the present invention, the resistance for being connected to LED light side is additionally provided in the detection line, it is described
LED light is in parallel with a resistor on buzzer.
Compared with prior art, having the beneficial effect that acquired by the present invention：
The present invention possesses ground wire self-checking function, more directly represents ground wire kilter.The present invention possesses detection and connects
Ground good function, avoid due to imperfect earth it is good caused by personnel electricity wound or instrument burn.The innovation principle is simply clear,
Clamped " the earth " using earthing clamp, so formed conducting circuit, press small switch can detect at any time ground wire it is whether good
Ground connection.Buzzer buzzing and shine during good earth, if imperfect earth or earth-free, will not buzzing shine, have stronger
Identification is applicable to different operating environment.

Specific embodiment
Further details of narration is carried out to the present invention below in conjunction with attached drawing.
As shown in attached drawing 1-5, a kind of detection type tester ground wire, including ground wire 1, detection line 2, wire connection terminal 3, inspection
Survey module and earthing clamp 8；The ground wire 1 is connected between wire connection terminal and a clamping plate of earthing clamp 8, the detection
Line 2 is connected between wire connection terminal 3 and another clamping plate of earthing clamp 8；The detection module includes being sequentially connected in series detecting
DC power supply 4, detection switch 5 and warning device on line 2；The warning device includes the buzzer 7 being connected in detection line 2
With the LED light 6 being connected in parallel on buzzer 7.The resistance for being connected to 6 side of LED light, the LED are additionally provided in the detection line 2
Lamp 6 is in parallel with a resistor on buzzer 7.
The present invention has the function of self-checking function, detection earth-return circuit.Test module and ground wire 1, detection line 2 and earthing bar
10 form series loop.Before ground wire is accessed, whether the present apparatus is intact runs for detection first, due to 8 normality of earthing clamp
In closure state, from circuit, Pen-down detection switch 5 is formed, alarm sound occurs for buzzer 7, and LED light 6 shines, illustrates to be grounded
Well, can be used normally.Then present apparatus wire connection terminal 3 is connected to 9 shell of tester, earthing clamp 8 is clamped into earthing bar
10, when detecting earth-return circuit, if earthing bar 10 there is a situation where to paint, is dirty or during compared with thick oxide layer, 8 both ends of earthing clamp without
Method is enough into access, and warning device does not start；It, can be by ground wire 1, inspection if the earthing bar 10 that earthing clamp 8 is contacted turns on well
Survey line 2 and test module form circuit, and buzzer 7 is alarmed, and LED light 6 shines, and represent that ground connection is good.
The principle of the invention is simply clear, is clamped " the earth " using earthing clamp, and then forms conducting circuit, presses small switch
Can detect at any time ground wire whether good earth.It buzzer buzzing and shines during good earth, if imperfect earth or earth-free,
Then will not buzzing shine, have stronger identification, be applicable to different operating environment.The technique effect that the present invention obtains：1、
Possess ground wire self-checking function, more directly represent ground wire kilter.2nd, possess detection ground connection good function, avoid
Personnel's electricity wound or instrument caused by since imperfect earth is good are burnt.The present invention has obtained well in checking experiment working site
Use, significant effect is capable of deciding whether good reliable ground.The achievement, which may extend to, all needs the electrical of the earthing of casing to set
It is standby, have a wide range of applications occasion.My team is mainly made using teams and groups' inventory, as can obtaining promoting on a large scale makes
With then cost can be reduced further, be can be controlled in 10 yuan, have apparent economic value.Though protective grounding line cost is low,
The safety of related personnel and electrical equipment can be protected, has met the epoch melody of " popular foundation millions of people innovation ".The present apparatus originates from
The electrical test specific works in substation equipment maintenance and repair are but not limited to power transformation specialty, it is existing to can be applied to other electric power, capital construction work
Field can also apply to the every aspect of production and living.
Embodiment described above is merely a preferred embodiment of the present invention, and the simultaneously exhaustion of the feasible implementation of non-invention.It is right
For persons skilled in the art, on the premise of without departing substantially from the principle of the invention and spirit to any aobvious made by it and
The change being clear to should be all contemplated as falling within the claims of the present invention.
