The pipeline of grounding requirement, each intersegmental answers well conducting.When between each pair ring flange or nipple, resistance value is more than 0.03 Ω, should
Wire is had to bridge ".Can be seen that whether meet the requirement of antistatic between ring flange or nipple and be from above-mentioned regulation
No need to set up jumper to be size according to transition resistance to determine.If ring flange two ends transition resistance is more than 0.03 Ω
When, electrostatic is just assembled easily at ring flange, produces electric spark, easily causes security incident, so jumper pair should be used
Ring flange two ends are bridged so that the transition resistance at ring flange two ends is in the scope required by specification.In actual applications,
The pipeline that conveying has the material of fire, explosion danger is in outdoor state, exposes to the sun and rain all the year round and leads to connecting bolt or jumper
Corrosion condition occurs, and or when conveying material the vibrations that produce cause loosening or coming off of connecting bolt or jumper wire joint,
Both situations all can cause the loose contact of ring flange two ends or transition resistance to be more than 0.03 Ω.But according to relevant regulations pair
In combustible and explosive area lightning protection detection be every half a year once, and this detection can only be entered using special instrument by professional person
OK, thus can not find that ring flange two ends transition resistance exceedes regulation in time.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of pipeline transition resistance to survey connection device,
This device can solve the problems, such as cannot find that transition resistance exceedes regulation in time well.
For reaching above-mentioned requirements, this utility model adopts the technical scheme that：A kind of pipeline transition resistance is provided to survey tipping
Put, including the transition resistance tester for testing transition resistance resistance, transition resistance tester is provided with display screen, also includes
Test casing and the supplying cell being connected with transition resistance tester by electric power connection line, transition resistance tester and power supply electricity
Pond may be contained within testing in casing, test casing is provided with the switch for starting and cutting out transition resistance tester, and surveys
Examination casing is provided with the observation window for observing display screen；It is mounted on testing wire terminal on the relative side wall of test casing two
And jumper wire joint, one of them is tested wire terminal and is connected with the input of transition resistance tester, separately by the first p-wire
One test wire terminal is connected with the outfan of transition resistance tester by the second p-wire；Connect between two jumper wire joints
It is connected to jumper.
This pipeline transition resistance survey connection device has the advantage that as follows：
(1) this device is erected on ring flange, and test wire terminal is connected all the time with the connecting bolt at ring flange two ends, when
When needing detection, the switch pressed on test casing starts transition resistance tester, and the test result of transition resistance can show
On the display screen of transition resistance tester, simple to operate, visual result, even do not possess lightning protection to detect the general of professional technique
Logical patrol officer also can be detected, is easy to find in time and process potential danger source, improves the safety of combustible and explosive area；
(2) carry jumper in this device, when detection finds that ring flange two ends transition resistance is more than 0.03 Ω, directly will
Two jumper wire joints are wired to the connecting bolt i.e. achievable bridging at ring flange two ends, need not individually connect bridging
Line；The jumper that this carries can also be connected when transition resistance is less than 0.03 Ω, it is to avoid transition resistance increases suddenly formation peace
Full hidden danger；
(3) test casing is made using explosion-proof lamp, internal filling epoxy resin glue, has fire-retardant, shockproof, waterproof, anti-
The feature of dirt is it is adaptable to flammable and explosive substance such as produces, stores, conveying at the complicated place of environment；
(4) this device is used battery as power supply, has long service life, no territory of use's restriction, safe and reliable spy
Point.
Brief description
Accompanying drawing described herein is used for providing further understanding of the present application, constitutes the part of the application, at this
Represent same or analogous part, the schematic description and description of the application using identical reference number in a little accompanying drawings
For explaining the application, do not constitute the improper restriction to the application.In the accompanying drawings：
Fig. 1 is the structural representation of the application；
