Edge protective layer is made, and electric power or information are transferred to the conducting wire at another place from one.The insulation performance of cable is to the electrical of cable
Performance influence is very big, and insulation performance is lower, and electric property is poorer, and insulation performance is higher, and electric property is better.The insulating properties of cable
Can be the important parameter of cable, because in newly-built, reconstruction, in the power engineering of enlarging, needing to carry out Insulation test to relevant cables,
To ensure the electric property of cable.
Currently, the insulation detection device of detection cable can only once carry out cable single shorted to earth detection or right
Two cores of unit cable carry out phase fault detection.In general power engineering, the quantity of cable has hundreds of, every cable
Cable core few then 6-7 cores, at most 16-18 cores.Insulation monitoring, inspection are carried out to every core of cable according to insulation detection device
It repaiies personnel to be grounded detection line one end, the single line core of another termination cable, or will be exhausted between two core of core of two cables
Edge is detected, in this way, in detection process, needs the number detected more, and extremely inefficient, time-consuming, and number of repetition is too
More, staff is also easy fatigue.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of cable insulation detection auxiliary device, to reach cable
Detection number is reduced when Insulation test detects, and improves the technique effect of working efficiency.
To achieve the above object, the technical solution of the utility model is：
A kind of cable insulation detection auxiliary device, which is characterized in that including panel, be provided on the panel positive and negative
Pole binding post, several change-over switches SA and several core hole XS to match with change-over switch, the anode and cathode connect
Terminal is connected with the positive and cathode main traverse line in panel respectively, and the cathode main traverse line is connected with ground wire, the conversion
The one end switch SA includes positive and negative and empty three terminals, and the other end is connected with core hole XS, and the change-over switch SA's just connects
Line end is connected with positive main traverse line, and the negative terminals of the change-over switch SA are connected with cathode main traverse line, and the conversion is opened
The empty terminals for closing SA are hanging.
Compared with prior art, advantage is the utility model：
1, the insulation situation of all cables core over the ground can disposably be detected using the utility model.
2, the state by adjusting conversion switch can detect the insulation situation of a cable core and other cables core successively.
3, connecting portion is connected using cellular type, to prevent wiring exposed, personnel is caused to get an electric shock.
4, detection number can be greatly reduced using the utility model, improve detection efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the operating diagram of the utility model；
The meaning of reference numeral in figure：1, insulation detection device, 2, cable.
Specific implementation mode
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment 1：
A kind of cable insulation detection auxiliary device, which is characterized in that including panel, be provided on the panel positive and negative
The core hole XS1-XS17 that pole binding post, 17 change-over switch SA1-SA17 and 17 match with change-over switch, the anode
It is connected respectively with the positive and cathode main traverse line in panel with negative terminal, the cathode main traverse line is connected with ground wire,
The one end the change-over switch SA includes positive and negative and empty three terminals, and the other end is connected with core hole XS, the change-over switch
The positive terminals of SA are connected with positive main traverse line, and the negative terminals of the change-over switch SA are connected with cathode main traverse line, institute
The empty terminals for stating change-over switch SA are hanging.
For detecting the cable of 17 cores, elementary diagram is as shown in Figure 2：
The anode and cathode of insulation detection device 1 are connected with the anode and negative terminal of the utility model respectively first
It connects, the core hole XS1-XS17 of the utility model is connected with the cable of 17 cores 2 respectively, and the other end of cable 2 is carried out accordingly
Measure keeps cable 2 hanging, earth-free.
Detecting step is as follows：
1, the change-over switch SA1-SA17 of the utility model is first switched to positive terminals by testing crew, electricity all at this time
Cable 2 is connected to the anode of insulation detection device 1；
2 then click insulation detection device 1 start button.Equal data to be tested are stablized, if Insulation monitoring is normal,
Illustrate that the insulation between all cores of the cable and ground is good；If insulation is problematic, keep insulation detection device 1 in detection shape
Then state passes sequentially through switching switch SA1-SA17 to empty terminals, if after switching, Insulation monitoring restores normally, then with this
The corresponding core insulation of a change-over switch is problematic, and is recorded to this, and it is " sky " to keep this problematic core that insulate
State, then other change-over switches switch to positive terminals, remaining core detects again, judges whether other cores exhausted
Edge is normal；
If 3, above-mentioned core insulation against ground no problem.Keep insulation detection device 1 in detecting state, change-over switch SA1-
SA17 switches to positive terminals, then successively will switching switching to negative terminals, the core that detects at this time and other cores it
Between insulation situation.If the data of the detection of insulation detection device 1 are normal, the core insulation of the cable 2 is normal.If having one
For root when switching to negative terminals, the data exception of the detection of insulation detection device 1 keeps the state of this core, then successively will
The switching switching of present positive terminals is to dummy status, in handoff procedure, cause data restore that normal root core just with
It insulate between this abnormal core problematic, is then recorded.
4, after being completed, insulation detection device 1 is closed, disconnects insulation detection device 1, and by change-over switch SA1-
SA17 switches to negative terminals, it is made to discharge all cables core.Finally its physics wiring is removed again.
Above-described embodiment simply to illustrate that the utility model technical concepts and features, the purpose is to be to allow this field
Interior those of ordinary skill can understand the content of the utility model and implement according to this, can not limit the utility model with this
Protection domain.The equivalent changes or modifications that every essence according to the utility model content is made, should all cover in this reality
With in novel protection domain.
