Embodiment
The embodiment of the present invention is further described below in conjunction with accompanying drawing.
A kind of hv cable termination can shunting anti-theft grounding and measurement apparatus, as shown in figure 1, including cable termination 1, eventually
Hold tail pipe 2, grounded metal support 4, spring anti-theft grounding to be measured in flakes with shunting and hang pole.The cable termination 1 is arranged on
The upper end of grounded metal support 4, the terminal tail pipe 2 is by spring anti-theft grounding in flakes installed in grounded metal support 4
Lower end, fastened in flakes with the junction of metallic support 4 by bolt 3 in spring anti-theft grounding.
By anti-theft grounding frame 6-1 and two ground connection, 6-2 is formed the spring anti-theft grounding in flakes in flakes, such as Fig. 2 and Fig. 3
Shown, two one end for being grounded 6-2 in flakes are connected by spring hinge 5 with anti-theft grounding frame 6-1, two ground connection two panels 6-
2 other end is superimposed together, two in flakes on be equipped with a metal hanger 6-3.Under normal operating conditions, two connect
Ground presses mutually in flakes, keeps earth-continuity state；When carrying out partial discharge test, measure extension pole with shunting and hang over two in flakes
Metal hanger 6-3 on, because two metallic grounds are respectively arranged with spring hinge 5 in flakes, when pull downward on shunting measurement hang pole
When, two ground connection in flakes open by 6-2 separation, is transformed into test mode.When unclamping measurement extension pole, in the presence of spring hinge 5
6-2 is pressed metallic ground again in flakes, recovers normal operating condition.
The shunting measurement hangs pole by insulated handle 7, telescopic insulating bar 8, drainage metal hook 9, sensor spacing ring
10th, electrical verification warning indicator 11, buzzer 12, alarm lamp 13, electrical verification contact 14 and extension pole support frame 15 are formed.It is described to stretch
Contracting insulating bar 8 is scalable to be arranged on the upper end of insulated handle 7, and the extension pole support frame 15 is arranged on the upper end of telescopic insulation rod 8,
The drainage metal hook 9 is two and is arranged on the upper end both sides for hanging pole support frame 15, and the sensor spacing ring 10 is two
Individual and installed in 15 central both sides of pole support frame are hung, the electrical verification warning indicator 11 is arranged on by electrical verification contact 14 and hangs pole branch
The bottom center of support 15, the electrical verification warning indicator 11, buzzer 12 are arranged on the surface of electrical verification warning indicator 11.
The present invention application method be：In normal operating condition, it is grounded in the presence of two spring hinges 5 and protects in flakes
Hold closure state；When being tested using shunting measurement extension pole, by high-frequency test sensor card mounted in drainage metal hook 9
On, sensor nonvoluntary slip on drainage metal hook 9 can be kept in the presence of sensor spacing ring 10.Subsequent basis
Terminal highly adjusts the length of telescopic insulating pole 8, and tester holds insulated handle 7 and drainage metal hook 9 is hung over into spring
On the metal hanger 6 of anti-theft grounding in flakes, and pull open downwards, now terminal tail pipe 2 will link up with 9 and ground connection gold by drainage metal
Belong to support 4 and form earth-return circuit, earth current is branched on drainage metal hook 9, utilizes the biography on drainage metal hook 9
Partial discharge signal in sensor measurement earth current, is converted to test mode.Simultaneously as drainage metal hook 9 is alarmed with electrical verification
The electrical verification contact 14 of indicator 11 is connected, and electrical verification operation has also been carried out during operation is mounted, if cable termination ground connection is different
Often result in ground connection position and higher induced electricity be present, the buzzer 12 of electrical verification warning indicator 11 can send buzzing, and flash alarm
Indicator lamp 13, operating personnel are reminded to terminate test job.When the test is finished, remove shunting measurement and hang pole, in spring hinge 5
In the presence of, spring anti-theft grounding re-closes in flakes, state of resuming operation.Said structure is not only that partial discharge test provides
Condition, while the normal operation of cable termination is also assures that, it also avoid using existing ground wire during ground connection to steal
Phenomenon.
It is emphasized that embodiment of the present invention is illustrative, rather than it is limited, therefore the present invention is simultaneously
The embodiment described in embodiment is not limited to, it is every to be drawn by those skilled in the art's technique according to the invention scheme
Other embodiment, also belong to the scope of protection of the invention.
