1.2.5 being conducted.In addition, the traversing through end of earth jack conductor 1.2.4 and the embedded spiral shell being embedded in bridge joint insulation shell 1.2.9
Female 1.2.10, which is matched, to be tightened, and is integrally formed with reaching push rod insulation shell 1.2.1 and bridge joint insulation shell 1.2.9, to seal
Fill the bridging component set in all.In conjunction with Figure 24 as it can be seen that when being crimped with conductive line jack conductor 1.2.13 and ground wire jack conductor
When being 1.2.14 inserted into corresponding transition jack conductor 1.2.3 and earth jack conductor 1.2.4, this three conductor wire institutes
The corresponding ends A, the ends B and the ends PE (ground terminal) will also be bridged, be connected, i.e., the side CT bis- times phase windings formed closed loops and
Converge ground connection.
In conjunction with Figure 23 with Figure 24 it is found that when bridge joint core component 1 be not connected with the bridge joint pairing grafting of matching component 2
When, the corresponding jack conductor 1.2.3 of transition two-by-two and earth jack conductor 1.2.4 is to be connected with each other conducting.Which ensures that
Bis- sides CT are not in open circuit phenomenon, avoid bis- sides CT because high pressure caused by open circuit jeopardizes personnel and equipment
Safety, and an only common point concentrates ground connection, meets the requirement of CT secondary side end loops ground connection.
As shown in figure 25, when needing to carry out current signal detection to bis- sides CT wherein certain corresponding two endpoint
When, first two measurement test pencils of current detecting instrument are inserted into respectively in corresponding two transition jack conductor 1.2.3, are then made
The correspondence being inserted on push rod insulation shell 1.2.1 according to Impact direction shown in Figure 25 dotted arrows with special isolation screwdriver is exhausted
Edge bar is stored in through-hole, is pushed insulation push rod 1.2.2, is then pushed bridge joint in corresponding three ends bridging piece 1.2.5 and free end bridge
Bridge joint block 1.2.7 between contact pin 1.2.6 a so that extension of three end bridging piece 1.2.5 and corresponding single-ended bridging piece
1.2.6 the bridge joint between disconnects, to allow current detecting instrument to detect two corresponding current signals between terminal A, B.It will be electric
Numerical signal in stream detection instrument is compared with the numerical signal in the detection instrument on detection device end, it can be ensured that inspection
The accuracy and formedness of detection instrument on measurement equipment end.
In addition, bridge joint block 1.2.7 is placed in the special rail slot space on bridge joint insulation shell 1.2.9, ensure in this way
Bridge joint block 1.2.7 can be vertically moved when being pushed or when bridge joint spring 1.2.8 restores, and it is existing to avoid the occurrence of offset, interim card
As so that it is guaranteed that bridging stability and the safety of anti-open circuit.
As shown in figure 26, it after current detecting instrument has detected current signal of corresponding two of this group between terminal A, B, first removes
Go out special isolation screwdriver, makes bridge joint of the corresponding bridge joint between three end bridging piece 1.2.5 extensions and single-ended bridging piece 1.2.6
Block 1.2.7 sets back under the elastic force effect of bridge joint spring 1.2.8, the bridge joint between correspondence two point A, B to restore tested,
Make 2 points of A, B be connected to be connected.Detection instrument is finally withdrawn from, detection is completed.
After having been detected to bis- sides CT, the detection device of recovery bis- sides CT and secondary singal collection terminal is being needed just
Often connection, makes the detection device of secondary singal collection terminal re-start acquisition, detection, record to the current signal of the sides CT.Prepare
The state of the bridge joint core component 2 of connection is as shown in Figure 27 and Figure 28.Sectional view such as Figure 27 shown in part (a) of Figure 27
(b) shown in part.Sectional view is as shown in part (b) of Figure 28 shown in part (a) of Figure 28.
Core component 2 is bridged with after the bridge joint pairing grafting of matching component 1, the connection between corresponding terminal A and A ', B and B ' is logical
Cross bridge joint matching component 2 on transition pin conductor 2.3.4 respectively with bridge joint core component 1 on transition jack conductor 1.2.3
It carries out mating so that corresponding terminal A and A ', B and B ' are formed and be connected.As shown in part (a) of Figure 29, mating group is being bridged
Part 2 and bridge joint core component 1 it is mating during, after pin conductor is in contact with jack conductor, with bridge it is mating
Component 2 deepens continuously with bridge joint the mating of core component 1, and the mating insulation push rod 2.3.2 bridged in matching component 2 will be pushed away
Insulation push rod 1.2.2 in dynamic bridge joint core component 1, then pushes bridge joint in the extension of corresponding three ends bridging piece 1.2.5
Bridge joint block 1.2.7 between single-ended bridging piece 1.2.6, compression bridge joint spring 1.2.8, makes the bridge joint between corresponding points between A and B connect
Connect disconnection.As shown in part (b) of Figure 29, after the completion of bridge joint matching component 2 and bridge joint core component 1 match, bridge joint is mating
Locking outer shroud 2.1 on component 2 is meshed with the bridge joint core shell 1.1 of bridge joint core component 1, locks at this time so that bridge joint
Matching component 2 forms an entirety with bridge joint core component 1.

Dynamic bridge joint block 1.2.7 makes A and Na bridge, and B and Nb is bridged, and C and Nc is bridged, and therefore, the sides CT socket connection component F1 has anti-
Function of open.Meanwhile neutral point Na, neutral point Nb, neutral point Nc are to connect conducting by three end bridging pieces with earth point N (PE)
, and by the earth jack conductor 1.2.4 ground connection N (PE) of the center of three end bridging piece 1.2.5, meet CT secondary side collection
The requirement of middle one point earth.
When bridging core component 1 and bridge joint matching component 2 connects, the insulation push rod in matching component 2 is bridged bridge joint
Bridge joint block 1.2.7 in core component 1 is pushed open, that is, is disconnected the bridge joint of A and Na, the bridge joint of B and Nb, the bridge of C and Nc
It connects so that corresponding line is mutually straight-through, i.e. the A2 of the side the A1 and CT tapped component of the sides CT jack assemblies is conducted, the sides CT socket
The Na of the side the Na and CT plug-assembly of component is conducted.Other straight-through situations are similar, repeat no more.
When the sides CT plug connection component is by plug disjunction, the sides CT socket connection component keeps the state of anti-open circuit, can
Prevent CT secondary sides open a way, avoid the problem that CT secondary sides open a way to be formed high pressure jeopardize the person and equipment safety.Similarly, when secondary
When equipment side socket connection component F2 is by plug disjunction, secondary device side plug connection component T2 is maintained to anti-open circuit
State.Since anti-open circuit is realized by single-phase bridge joint, since the equipment such as each independent protection or measurement can obtain respectively
It is formed into a loop to corresponding one group of phase line and zero curve, when needing on-line operation to safeguard, measure, each phase can be carried out independent
Measurement, observation.
