Background technology
Present EIlog subsurface equipment structure is all be made up of upper 31 core sockets, electronics circuit, lower 31 core plugs, in instrument wiring, except the wiring that this quasi-instrument is used, all the other wiring are all and run through line.Run through line resistance between upper and lower 31 core joints and be about 0.2 Ω, core and tool housing insulate and are greater than 500M Ω.
When daily apparatus guarantee checks, the line that runs through of instrument is all the insulation break-make performance running through line with megohmmeter and multimeter measurement.But because subsurface equipment is of a great variety, each instrument run through that line is numbered at 31 core plug places, position is different, so its insulation break-make performance checking process is loaded down with trivial details, and if select mistake to run through line wiring when using megger to detect the insulativity of core and shell to number, easily burn instrument.
For insulating short section, common detection methods all will need to detect its break-make, insulativity to 31 each roots running through line in instrument.Though method is simple, process is comparatively loaded down with trivial details.
There is no the device of the insulation of special detection instrument, break-make performance at present.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of oil instrument and insulate open close Performance Detection box, and this detection box uses the break-make performance of all wiring of self-powered disposable inspection apparatus.Can also insulating property between all wiring of disposable detection and shell for instruments such as three PARAMETERSInstrument, flexible nipple, rotating short-knot, eccentric pipe nipple, insulating short sections.
The purpose of this utility model is realized by following concrete technical scheme:
A kind of oil instrument insulate open close Performance Detection box, and comprise 31 core terminal boxes and lower 31 core sockets, described time 31 core sockets are provided with 31 connector lugs be connected in parallel; Described upper 31 core terminal boxes are respectively equipped with testing circuit, upper 31 core plugs be connected on testing circuit, fluorescent tube indicator and megohmmeter jack; Described fluorescent tube indicator is provided with 31 pilot lamp and a shift switch.
Further, described testing circuit comprises be connected in parallel 31 connector lugs corresponding with 31 connector lugs of lower core socket, each connector lug is respectively equipped with light emitting diode, 31 connector lugs after being connected in parallel connect power supply and resistance respectively by shift switch, the negative pole end connecting power supply is connected to megohmmeter, and contact resistance end is connected to megger jack post.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of oil instrument insulate open close Performance Detection box, comprises 31 core terminal boxes and lower 31 core sockets 2.Wherein, lower 31 core sockets 2 are connected with handle 1, lower 31 core sockets 2 are provided with 31 connector lugs be connected in parallel.Upper 31 core terminal boxes are respectively equipped with testing circuit, upper 31 core plugs 3 be connected on testing circuit, fluorescent tube indicator 5 and multimeter jack 6; Fluorescent tube indicator 5 is provided with 31 pilot lamp and a shift switch 7.Upper 31 core terminal boxes are provided with lift hand 4.
As shown in Figure 2, testing circuit comprises be connected in parallel 31 connector lugs corresponding with 31 connector lugs of lower 31 core sockets, each connector lug is respectively equipped with light emitting diode D, 31 connector lugs after being connected in parallel connect power supply E and resistance R respectively by fork shift switch (K) 7, the negative pole end connecting power supply E is connected to megohmmeter, and contact resistance end is connected to megger jack post.
As shown in Figure 3, this detection box is made up of upper 31 core terminal boxes and lower 31 core socket two parts.When detecting instrument, the order of connection is detect the lower 31 core sockets of the upper 31 core terminal boxes of box, instrument to be detected, pick-up unit from top to bottom.Because downhole instruments for petroleum logging upper and lower joint specification is identical, the 31 core sockets identical with its specification and 31 core plugs are adopted to dock with instrument so this detection is closed.
Upper 31 core terminal boxes are made up of fork shift switch 7, power supply E, light emitting diode D, 31 core plugs etc.All wiring cores whole short circuit in inside on lower 31 core sockets.Power and energy is responsible for by fork shift switch is that Insulation monitoring or break-make detect.
During detecting instrument through track break-make, on instrument to be detected, 31 core sockets connect the upper 31 core terminal boxes of pick-up unit, and lower 31 core plugs of instrument to be detected connect the lower 31 core sockets of pick-up unit.The upper 31 core terminal box built-in 3V power supply detecting box is independently-powered to all cable cores, each wiring core is all connected a light emitting diode, and all wiring short circuits are connected together, if the wiring at upper 31 core plug places is through track by lower 31 core sockets, then circuit loop is formed, and light emitting diode is lighted.If the wiring at upper 31 core plug places is not run through line, then pick-up unit cannot forming circuit loop, and diode does not work.In like manner, if open circuit appears in instrument through track, run through with this root the light emitting diode that line connects and do not work.
When detecting box and being in Insulation monitoring function, when fork shift switch is in " Insulation monitoring " position, detect that box is self-powered disconnects with 31 core sockets on instrument, use megohmmeter is powered to all wiring, and megohmmeter negative pole connects tool housing.If instrument insulating property are good, then this line indication light diode does not work, otherwise diode is lighted.
The self-inspection of device: by the direct short circuit of two parts up and down of device, when on off test got to by switch, all diode lights light, namely illustrates that device is intact.
Line on-off function is run through to detect three PARAMETERSInstrument:
1) first device is connected with three PARAMETERSInstrument.
2) carry out on off test, shift switch gets on off test, built-in 3v power work, if the diode lights of corresponding core lights, then illustrates that this line leads directly to, otherwise has open circuit to exist.
3) Insulation test is carried out, shift switch gets to Insulation test, disconnects built-in 3v power supply, removes device lower sub, megohmmeter positive pole connects piecing devices jack, negative pole reception testing tool shell, proving installation working power is manually produced by megohmmeter, if the diode lights of corresponding core does not work, illustrate that the insulation of this line is good, otherwise illustrate this line insulation difference or and casing insulation value be 0, circuit turn-on, diode lights is lighted.
More than show and describe ultimate principle of the present utility model and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
