Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; The present invention includes cable termination 1 and cable checking end 2; It is characterized in that: each relay K 1～K8 of cable termination 1 for being connected in parallel; And at the normally opened contact that is in series with a relay on the next relay; The parallelly connected output port of first relay K 1 and above-mentioned parallel circuit is connected with low capacity one pole air switch QF in the cable checking end 2, and low capacity one pole air switch QF is connected with direct supply again, the LED 1～LED8 of cable checking end 2 for being connected in parallel; Direct supply is connected with the parallelly connected output port of this cable checking end 2 again, is parallelly connected input port separately between cable termination 1 and cable checking end 2.
Each relay K 1～K8 chooses the DC electronic relay of PV type, and the Control current scope is: 2～25mA, and voltage range is: 3～20V; Perhaps choose solid-state relay DC.
The selection voltage range of LED 1～LED8 is 2V, and Control current is 10mA.
Direct supply is chosen 6～9V.
This wire is made up of two parts: cable termination (being the indirectly measurement end), and utilize the apish school of relay line action wherein to connect cable core by root, control measurement indirectly to each bar heart yearn; Cable checking end (being direct measuring junction); When school informant person inserts cable core by root, connect relay corresponding in the cable termination through the electric wire heart yearn, make its normal opened contact adhesive; Connect next loop by root; Utilize on the cable checking end corresponding light emitting diode to prove, that of the heart yearn of access and the other end is corresponding, carries out comprehensive school line.
The practical application of cable checking instrument: if utilize cable checking instrument that one 8 core umbilical cable is carried out the school line, the lead wire size that need connect is: A411, B411, C411; A421, B421, C421, N421.Its operation steps is following:
1): for fear of producing school line mistake, we carry out corresponding layout and perform record institute's school wire size and drawing number earlier: 1#-A411; 2#-B411; 3#-C411; 4#-A421; 5#-B421; 6#-C421; 7#-N421.
2) cable termination is linked into the non-measuring junction of cable; During wiring, the 0# line both can have been received on the steel band of sheathed cable for measuring common line; Also can insert (because according to electrical installation project standard and construction procedure in the station through earth mat; The all completion before this wiring work of general earth mat), also can receive the concentric line (this line is the school line usefulness of constructing for ease, and most cables wherein always are provided with a painted different concentric line) of cable core; The gauger can specifically select according to actual conditions, but it is good and firm to guarantee that tie-in line will contact.In addition, if we select ground wire (net) as concentric line.Then 8 heart yearns are received arbitrarily on 1～8# removable wiring terminal in order, made its contact good and firm.Attention is when the order wiring, and the centre does not allow vacancy.
3) the cable checking end is linked into the measuring junction of cable, the 0# line is corresponding with the other end during wiring, receives on the ground wire (net); 8 heart yearns of cable by the 1# removable terminal block overlap joint of root with the cable checking end, if the light emitting diode (LFD1) of 1# is bright, are just proved that the line that is connect holds corresponding 1# line with other just; The 1# line is connected on securely on the 1# terminal of cable checking end, then other 7 is overlapped with 2#, if LED2 is bright; The just explanation heart yearn that connects is corresponding with other end 2# line, is fixed firmly.In like manner, but the school goes out other 6 leads.
4) according to 1) corresponding wire size, put corresponding terminal number for the cable two ends.
The configuration of element: QF can choose low capacity one pole air switch; The optional cut-off stream of relay K 1～K8 electronic relay (as: PV type), the Control current scope is: 2～25mA: voltage range is: 3～20V.Also can select the solid-state relay (DC) of present widespread use for use; (LED1～LED8) can control voltage according to relay to light emitting diode, electric current is selected to carry out to confirm that specifically be typically chosen in about 2V, Control current is generally selected about 10mA; Direct supply is selected its voltage height and amount of capacity according to the actual parameter of joining relay.Generally get 6～9V.
Except that function described in the literary composition, but this wire expanded application also both can be used as test lamp and used, also can expand to the above cable checking instrument of 24 cores according to the actual conditions in the construction.
