Specific embodiment
The embodiment of the present invention is further described below in conjunction with attached drawing.
A kind of hv cable termination can shunt anti-theft grounding and measuring device, as shown in Figure 1, including cable termination 1, eventually
It holds tail pipe 2, grounded metal bracket 4, spring anti-theft grounding to measure in flakes with shunt and hangs pole.The cable termination 1 is mounted on
The upper end of grounded metal bracket 4, the terminal tail pipe 2 are mounted on grounded metal bracket 4 by spring anti-theft grounding in flakes
Lower end is fastened with 4 junction of metallic support by bolt 3 in flakes in spring anti-theft grounding.
By anti-theft grounding frame 6-1 and two ground connection, 6-2 is constituted the spring anti-theft grounding in flakes in flakes, such as Fig. 2 and Fig. 3
Shown, two ground connection pass through spring hinge 5 and are connected with anti-theft grounding frame 6-1 in one end of 6-2 in flakes, and two are grounded in flakes
The other end of 6-2 is superimposed together, two in flakes on be equipped with a metal hanger 6-3.Under normal operating conditions, two
Ground connection pressing mutually in flakes, keeps earth-continuity state；When carrying out partial discharge test, extension pole is measured with shunt and hangs over two companies
On the metal hanger 6-3 of piece, since two metallic grounds are respectively arranged with spring hinge 5 in flakes, hung when pulling downward on shunt measurement
When pole, two ground connection in flakes open by 6-2 separation, is transformed into test mode.When unclamping measurement extension pole, in the effect of spring hinge 5
6-2 is pressed lower metallic ground again in flakes, restores normal operating condition.
The shunt measurement hangs pole and links up with 9, sensor stop collar by insulated handle 7, telescopic insulating bar 8, drainage metal
10, electrical verification warning indicator 11, buzzer 12, alarm lamp 13, electrical verification contact 14 and extension pole support frame 15 are constituted.It is described to stretch
Contracting insulating bar 8 is scalable to be mounted on 7 upper end of insulated handle, and the extension pole support frame 15 is mounted on the upper end of telescopic insulation rod 8,
The drainage metal hook 9 is two and is mounted on the upper end two sides for hanging pole support frame 15, and the sensor stop collar 10 is two
A and be mounted on and hang the central two sides of pole support frame 15, the electrical verification warning indicator 11 is mounted on by electrical verification contact 14 and hangs pole branch
15 bottom center of support, the alarm lamp 13, buzzer 12 are mounted on the surface of electrical verification warning indicator 11.
Application method of the invention are as follows: in normal operating condition, be grounded under the action of two spring hinge 5 and protect in flakes
Hold closed state；When being tested using shunt measurement extension pole, by high-frequency test sensor card mounted in drainage metal hook 9
On, sensor nonvoluntary sliding on drainage metal hook 9 is able to maintain under the action of sensor stop collar 10.Subsequent basis
Terminal height adjusts the length of telescopic insulating pole 8, and tester holds insulated handle 7 and drainage metal hook 9 is hung over spring
It on the metal hanger 6 of anti-theft grounding in flakes, and pulls open downwards, terminal tail pipe 2 will link up with 9 and ground connection by drainage metal at this time
Metallic support 4 constitutes earth-return circuit, and earth current branches on drainage metal hook 9, using on drainage metal hook 9
Partial discharge signal in sensor measurement earth current, is converted to test mode.Simultaneously as drainage metal hook 9 and electrical verification report
The electrical verification contact 14 of alert indicator 11 is connected, and has also carried out electrical verification operation during mounting operation, if cable termination is grounded
Exception leads to be grounded position in the presence of higher induced electricity, and the buzzer 12 of electrical verification warning indicator 11 can issue buzzing, and flash report
Alert indicator light 13, reminds operator to terminate test job.When the test is finished, it removes shunt measurement and hangs pole, closed in spring
Under the action of page 5, spring anti-theft grounding re-closes in flakes, state of resuming operation.Above structure is not only that partial discharge test mentions
Condition has been supplied, while having also assured the normal operation of cable termination, existing ground line when also avoiding using ground connection
Steal phenomenon.
It is emphasized that embodiment of the present invention be it is illustrative, without being restrictive, therefore the present invention is simultaneously
It is not limited to embodiment described in specific embodiment, it is all to be obtained according to the technique and scheme of the present invention by those skilled in the art
Other embodiments, also belong to the scope of protection of the invention.
