Description
Technical field
The utility model relates to 10kV cable detection technical fields, more particularly, to a kind of 10kV cable ac voltage withstanding
Dedicated anticorona connector.
Background technique
For the weak link of route on its attachment, these defects of cable bring the safe operation of cable when cable is run
Great hidden danger, since the running environment of cable is more severe, maintenance, failure are detected all relatively difficult.Therefore, 10kV cable
After road either newly puts into operation or replaces connector, it is necessary to carry out stringent commissioning test." GB 50150-2006 electric device peace
Dress engineering electrical equipment commissioning test standard " cable of the completion that look for novelty needs to carry out pressure test, although pressure test is to examine
The most straightforward approach of cable quality is tested, but the defect of some local non-through of cable is surely sent out by the way that pressure test is different
It is existing, and the local defect on cable can be promoted further to develop deterioration under the high voltage of pressure test, these latent defects exist
Gradually development causes failure generation very common in distribution network systems after cable operation a period of time.
Can the cable ac voltage withstanding test in traditional technology only focuses on cable integrally completely bear the test of test voltage,
Its judgment criteria is whether cable has passed through ac voltage withstanding test, lacks the local damage that cable is likely to occur during the test
With the monitoring means of destruction, if there are shelf depreciations inside cable, but cable is still possibly able to try by ac voltage withstanding
It tests, internal defective cable continues to run, and there are certain risks for cable running safety.
In recent years, more and more power supply departments and cable O&M unit all can while ac voltage withstanding is tested synchronize hold
Measurement of partial discharge is opened up, and alternating-current voltage resistance test device is connect with tag and is still connected using original crocodile clip
Mode, this mode, will be in wedge angle burr portions when voltage does not also rise to partial discharge detection required value since there are wedge angle burrs
Position generates corona, inherently a kind of shelf depreciation of corona, therefore can identify Partial discharge signal source to testing staff and bring greatly
Corona interference is eliminated in puzzlement by the way of using grading shield at present, and wiring is complex, and in place by cable termination institute
The space set and cable it is different it is separate between safe distance limitation.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, it is resistance to provide a kind of 10kV cable exchange

Part and the second connector are fastenedly connected, and guarantee the reliability of connection；Cable termination is connected with high-voltage conducting wires again by the first connector
It connects.First connector, the surface of the second connector are smooth, are wrapped up cable termination by the first connector and the second connector,
It effectively prevents cable termination and generates corona there are tip, burr etc..
Further, the end of the cable termination is equipped with flat auxiliary connection, and the through-hole is set on auxiliary connection.
Flat auxiliary connection is set in cable termination, the contact surface of cable termination and the first connector, the second connector can be increased
Product.
Further, the one side that first connector, the second connector are contacted with auxiliary connection is smooth planar junction
Structure.The one side that first connector, the second connector are contacted with auxiliary connection is smooth planar structure, in this way can be with auxiliary connection
Flat structure matches, in connection, the first connector and the second connector can by auxiliary connection tightly be folded in the two
Between, and there is no gap, increase contact area between the two.
Further, auxiliary connection is wrapped in first when first connector, the second connector are connect with auxiliary connection
Between connector and the second connector.The size of first connector and the second connector is greater than the auxiliary connection of 10kV cable termination
Size so that the tip of auxiliary connection part, burr under action of high voltage there is no corona generation, while the first connector and
Two connectors surface itself is extremely smooth, so itself there will not be corona generation, therefore can play anticorona effect.
Further, one end that first connector is connect with high-voltage conducting wires is equipped with the plug of protrusion, plug and high pressure
Jack on conducting wire matches.It is connected by the jack of plug and high-voltage conducting wires, structure is simple, easy to operate.
Compared with prior art, beneficial effect is: a kind of 10kV cable ac voltage withstanding provided by the utility model is dedicated anti-
Corona connector, the high-voltage connection for eliminating alternating-current voltage resistance test device and 10kV cable terminal connection part position are because of wedge angle, burr etc.
Caused by electric field concentrate and generate corona problem；Simultaneously eliminate it is existing it is uniform cover by cable termination position space and
Meet each other the restricted problem of safe distance.
