Abstract
The utility model relates to a rotation type ultrasonic sensor fixing device, it includes telescopic link, universal turning round and the sensor, universal turning round is connected to the upper end of telescopic link, and the sensor is fixed on universal turning round. During the test, through adjusting nut with universal ball head pole control in the adjustable range, regulations of roating sphere head rod needs the pivoted direction, test no longer receives the restriction in on -the -spot GIS equipment structure and space, does not have aerial work, guarantee tester safety can be select the test point simultaneously wantonly and guarantee the data accuracy. The device lead wire passes from the telescopic link is inside, guarantees that the lead wire does not receive the damage.
Description
Technical field
This utility model is related to a kind of rotary ultrasonic ware sensor fastening device, belongs to electric power application.
Background technology
GIS ultrasound wave Partial Discharge Detecting Technology is it can be found that the absence of discharge such as the internal spring washer of GIS device loosens, dust dances in the air
Property defect.Larger due to decaying when ultrasonic signal is propagated in SF6 gas, so in local discharge signal no significant change
When, need to measure every one test point of 0.5 meter of selection.
When carrying out ultrasonic partial discharge detection, two staff are needed to be tested.One people carries on the back device Host in body
On, the moment operates to main frame, observes waveform, wave recording；Another human hand held sensor（Probe）Choose test point, by coupling
Mixture is smeared on a sensor, and supports sensor on GIS device shell with handss, until this point is completed.
In test, following two situations often occur：
1st, the air chamber of tested point is high away from ground, and tester ascends a height when testing, and due to the structure of GIS device column type, does not have
There is the appropriate point hanging seat belt, in especially winter, device housings are more sliding, sometimes consider for security standpoint, just ignore these
Test point.
2nd, the GIS device compact conformation near tested point, narrow space, such as in measurement circuit B phase chopper air chamber,
Because adjacent GIS device is nearer, need two testers to pierce below air chamber simultaneously, the collide with person, equipment etc. easily occur
Phenomenon, makes troubles to test job.
Utility model content
This utility model is directed to above-mentioned problems of the prior art, there is provided a kind of rotary type ultraphonic wave sensor is solid
Determine device, when solving test in prior art, the problem being limited by field apparatus structure and space.
The technical solution of the utility model is as follows：
Rotary ultrasonic ware sensor fastening device, including expansion link, Universal rotary head and sensor；The upper end of expansion link is even
Connect Universal rotary head, sensor is fixed on Universal rotary head.
Described expansion link includes expansion link I, expansion link II and buckle, and expansion link I is sleeved in expansion link II, expansion link
It is flexibly connected by buckle between I and expansion link II.
Described expansion link I and expansion link II is hollow stem.
Described Universal rotary head includes fixed mount, rotates ball rod and adjusting nut, described fixed mount include base and
Support, described support is two right-angled U framves be arrangeding in parallel, and support is provided with screwed hole and arc groove, adjusting nut
Threaded with screwed hole, rotate ball rod and be arranged in arc groove.
Described sensor is arranged in housing, and the lower section of sensor is provided with compression spring, and the top of housing is provided with Magnet.
The utility model has the advantages of it is as follows：
When the 1st, testing, do not limited by live GIS device structure and space；
2nd, there is not high-rise working, ensure tester's safety；
3rd, can arbitrarily choose test point and ensure that data is accurate；
4th, lead passes through inside expansion link, not easily damaged.

Specific embodiment
Embodiment
As illustrated, rotary ultrasonic ware sensor fastening device, including expansion link 1, Universal rotary head 2 and sensor 3；Stretch
The upper end of contracting bar connects Universal rotary head, and sensor is fixed on Universal rotary head.
Described expansion link includes expansion link I, expansion link II and buckle 7, and expansion link I and expansion link II is hollow stem, stretches
Contracting bar I is sleeved in expansion link II, is flexibly connected by buckle between expansion link I and expansion link II；Expansion link can elongate or
Shrink, rotate clockwise in the process can by lever lock extremely in this fixed position, afterwards rotate counterclockwise can release locked.
Described Universal rotary head includes fixed mount 8, rotates ball rod 9 and adjusting nut 10, and described fixed mount includes bottom
Seat and support, described support is two right-angled U framves be arrangeding in parallel, and support is provided with screwed hole and arc groove, adjusts
Nut is threadeded with screwed hole, rotates ball rod and is arranged in arc groove；By adjusting nut, multi-directional ball head rod is controlled
In adjustable extent, rotate ball rod and adjust the direction needing to rotate.
Described sensor is arranged in housing 11, and the lower section of sensor is provided with compression spring 12, and the top of housing is provided with
Magnet.
P-wire one end is connected with main frame, and the other end is entered by expansion link bottom, inside the body of rod, by flexible club head
Stretch out, be connected with the sensor being fixed on club head.
This utility model in certain transformer station GIS ultrasound wave partial discharge test, certain transformer station's GIS device compact conformation,
Narrow space, needs personnel to pierce development test job, building ring below air chamber at ordinary times in measurement circuit B phase chopper air chamber
Border is poor, condition is arduous, and Yi Fashengyin personnel collide with equipment and the personal injury that causes and device damage accident.This test job
In, staff is directly tested using " rotatable ultrasonic sensor " fixing device, and staff need not pierce below air chamber,
Avoid the problems such as occur colliding with the person, equipment, quick and precisely, safely and reliably complete test job.
In addition, in 66kV transformer station GIS ultrasound wave partial discharge test, due to 9 circuits of transformer station air chamber away from
Ground is very high, needs personnel to ascend a height operation, do not hang seat belt appropriate point when testing at ordinary times, easily occur personnel to fall down, simultaneously
The personal injury accident such as slide into.In this task, staff is directly surveyed using " rotatable ultrasonic sensor " fixing device
Examination, it is to avoid high-rise working does not hang the appropriate point of seat belt and winter device housings are more sliding, the problems such as personnel easily slide into, protects
Card test job is accurately quick, safety and stability is carried out.
