After confirming that all ground wires all take off, close disconnecting link, combination switch power transmission.If grid power blackout scope is big, institute's hanging ground-wire is more, just needs
Want dispatcher, operator constantly to verify, have omission unavoidably.Power grid enterprises' line with ground combined floodgate power transmission according to data
Accident case is of common occurrence, and the power equipment run is brought the biggest impact and destruction by this kind of accident, is electric power enterprise the most all the time
The problem that industry cannot be fully solved.If after end-of-job, can check on circuit with or without leaving over earth lead with a kind of instrument,
I.e. can reduce or avoid this type of contingency occurrence probability.
Insulating bar is defined as: the insulating tool operated charging equipment for the short time, as being switched on or switched off high pressure
Disconnecting switch, dropping fuse tool etc..
Electronics megger is defined as: for avoiding having an accident, for measuring the insulation resistance of various electric equipment.
Basic insulation Work tool: refer to directly operate charging equipment or contact and the Work tool of electrical body may be contacted.
The difference of this kind of Work tool and live working tools is in work process as short-time contact electrical body or noncontact charged
Body.Insulating bar and the distant table of electronics broadly fall into basic insulation Work tool category.
The insulating bar that tradition uses has machinery and a good feature of insulating properties, but function singleness, it is impossible to check circuit
On with or without leaving over ground wire.Invention one is needed now to ensure, outside its superperformance, circuit resistance to be checked, fundamentally stop
The maloperation phenomenons such as band ground wire power transmission.
Summary of the invention
In order to fundamentally stop the maloperation phenomenons such as band ground wire power transmission, the invention provides a kind of intelligence truly
Line with ground combined floodgate detection device can be prevented, except there is conventional insulator bar (or electroscope) insulating properties, mechanical performance and having by type
Outside the good basic functions such as effect length, it is also possible to detection circuit resistance, there is exhaustive earth lead function etc..
The present invention is achieved by the following technical solutions:
Intelligent anti-line with ground closes a floodgate and detects device, including detection part and insulating bar, it is characterised in that described inspection
Survey part is fixed on major insulation bar, is provided with high resistant in major insulation bar, and detection part is connected with the joint through high resistant, test section
Dividing and be arranged over earth terminal, major insulation bar lower end is provided with interface, and interface is used for connecting insulating bar.
Wherein, described test section divides and includes power supply, button, display unit, alarm unit, current amplification unit and Wei Chu
Reason device, described button and display unit be arranged on the shell of detection part, described microprocessor respectively with display unit,
Button, power supply, alarm unit, current amplification unit are connected.
Wherein, described current amplification unit includes non-contact current sensor, direct current amplifier, I/V transducer, non-
The minor leakage electric current detected is sent into microprocessor after direct current amplifier processes by contact current sensor, and I/V changes
Device is connected with microprocessor, for electric current, the conversion of voltage.
Wherein, described display unit is LED display.
Wherein, described power supply is the battery of detection partial interior.
Wherein, described alarm unit is buzzer.
Wherein, described joint is dismountable, according to electrical verification, operates and test is divided into various shape.
Wherein, described interface is hickey.
Compared with prior art, the invention have the benefit that
(1) fabricated structure, connected mode is simple and convenient, time saving and energy saving, can be greatly enhanced work efficiency, the most often
The contraction in length of individual unit, it is simple to use, carry, transport and keeping.
(2) line-to-ground situation can be detected, stop band ground wire and earthing power transmission, this type of pernicious operating accident.
(3) too much due to sky humidity or dust, effective length insulating bar surface leakage current crosses limit.There is this
Bright, operating personnel is when holding intelligent leakage current detection device insulating bar, so that it may be reached by LED display monitoring insulation
Whether support body of rod leakage current values transfinites, and prevents from getting an electric shock, protects user personal safety.
(4) operation joint is in addition to special selection epoxy material, and remaining all uses high-quality galvanized steel material；Test joint is then adopted
With galvanizing high-quality steel matter (or copper covered steel material).
(5) effective length insulating bar (1m/ joint) selects that intensity is big, the material of good insulation preformance, to ensure that insulating bar is original
Insulating properties and mechanical strength constant.
