Test pencil and multimeter are two kinds of the most frequently used measurement instruments, and test pencil can only be used for surveying electricity, can not be used for the school line; And multimeter can be used for surveying electricity, also can be used for the school line, but must two people cooperation carry out when being used for the school line; And indicator signal is not directly perceived, needs between two people to link up through communication incessantly, uses very inconvenient; So various cable checking method is arisen at the historic moment, send reception method etc. like school line lamp method, measuring resistance method and signal.
School line lamp method adopts dry cell as the pilot lamp power supply; Its school line method is similar with employing multimeter school line method; Need two people to cooperate and carry out, need to link up, inquire through communication whether pilot lamp lights incessantly between two people in the line process of school, use very inconvenience.
And that measuring resistance method, signal are sent reception method method is simple, suitable cable checking, but suitable cable core troubleshooting, and the measuring resistance method also receives the restriction of cable core quantity.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of cable core and surveys electric calibration equipment, not only can survey electricity to cable core, but also can make things convenient for the school line.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
This cable core is surveyed the secondary machine that is used with it when electric calibration equipment comprises main frame and school line; Main frame comprises housing and test pencil, the main school line circuit be located in the housing; Secondary machine comprises housing and the secondary school line circuit of being located in the housing, main school line circuit comprise a pair of be used to connect concentric line and tested heart yearn terminals, power supply and be used for LED lamp, the hummer of sound and light alarm; Secondary school line circuit also comprise a pair of be used to connect concentric line and tested heart yearn terminals, be used for LED lamp, the hummer of sound and light alarm.
Described test pencil is the digitizing test pencil.
The LED lamp of described main school line circuit is two that are in series, and also is parallel with SS on one of them LED lamp.
Also be in series with potentiometer between one terminals of described main school line circuit and the LED lamp.
Also be parallel with charging socket on the power supply of described main school line circuit.
In technique scheme; The cable core of the utility model is surveyed electric calibration equipment and is comprised main frame and secondary machine; Main frame comprises housing and test pencil, the main school line circuit be located in the housing; Secondary machine comprises housing and the secondary school line circuit of being located in the housing, main school line circuit comprise a pair of be used to connect concentric line and tested heart yearn terminals, power supply and be used for LED lamp, the hummer of sound and light alarm; Secondary school line circuit also comprise a pair of be used to connect concentric line and tested heart yearn terminals, be used for LED lamp, the hummer of sound and light alarm.Not only can realize the survey of heart yearn electricity through this device, and need not communication, can make things convenient for heart yearn to carry out verification.
Description of drawings
Fig. 1 is the interior circuit theory diagrams of shell of the main frame of the utility model;
Fig. 2 is the interior circuit theory diagrams of shell of the secondary machine of the utility model.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also Fig. 1～shown in Figure 2; The cable core of the utility model is surveyed the secondary machine 20 that is used with it when electric calibration equipment comprises main frame 10 with the school line; Main frame 10 comprises housing and test pencil 11, the main school line circuit be located in the housing; Secondary machine 20 comprises housing and the secondary school line circuit of being located in the housing, main school line circuit comprise a pair of be used to connect concentric line and tested heart yearn terminals A1, A2, power supply U 1 and be used for LED lamp L1, L2, the hummer H 1 of sound and light alarm; Secondary school line circuit also comprise a pair of be used to connect concentric line and tested heart yearn terminals B1, B2, be used for LED lamp L3, the hummer H2 of sound and light alarm.Described test pencil 11 is digitizing test pencil 11, has functions such as telescopic metallic test probe, screen display.The LED lamp of described main school line circuit is two that are in series, and also is parallel with SS S1 on the LED lamp L2 among Fig. 1, is used for that major-minor machine 20 is used or the selection of main frame 10 when using separately.Also be in series with potentiometer R1 between one terminals of described main school line circuit and the LED lamp, be used for the adjusting of sound and light signal intensity.Also be parallel with charging socket F1 on the power supply of described main school line circuit, power supply adopts the DC6V ickel-cadmium cell, realizes charge function.
This principle of work of surveying electric calibration equipment is following:
Respectively join operation personnel at the two ends of tested umbilical cable; Hand main frame 10 and secondary machine 20 respectively, and two terminals B1, the B2 of secondary machine 20 linked to each other with a heart yearn of earth terminal and tested cable respectively with connecting line, and a terminals A1 of main frame 10 links to each other with earth terminal through connecting line equally; With as concentric line; Another terminals A2 then touches the heart yearn of cable one by one through connecting line, send the sound and light alarm signal simultaneously until main frame 10 and secondary machine 20, explains that concentric line and verification heart yearn are connected in series with battery to have constituted a closed-loop path; Promptly find the pairing two ends of this cable core, and put corresponding wire size.In this way, repeat said process, pursue line and search, finish up to whole detection of umbilical cable heart yearn, and put corresponding wire size.In the line process of school, the two ends operating personnel is as the criterion with acousto-optic, AIS, proves that the school line is correct, so need not carry out any communication.
When umbilical cable is short distance, can adopt operation personnel to carry out main frame 10 and use separately: only need open SS S1, when the umbilical cable troubleshooting; Whether have electricity (must under the state that do not have electricity, detect umbilical cable whether same heart yearn), a terminals A1 wherein is connected to cable one end through connecting line with test pencil 11 if earlier detecting the umbilical cable of being searched; Another terminals A2 touches any heart yearn of the cable other end one by one through connecting line; In case the verification heart yearn correctly is communicated with, be connected in series closed-loop path of formation with battery, send the sound and light alarm signal on the main frame 10; Promptly find the pairing two ends of this heart yearn, and put corresponding wire size.Repeat said process, pursue line and search, up to the umbilical cable heart yearn all detections finish, and put corresponding wire size and get final product.
Adopt the survey electricity calibration equipment of the utility model, simple in structure, carry with easy to use, help the site examining and repairing operation.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
