Description
Technical field
The utility model relates to ceramic insulator detection fields, and in particular to a kind of portable megameter.
Background technique
Ceramic insulator detection is a conventional project of transmission line of electricity maintenance repair maintenance, and carries out in the conventional project
When detection, megameter is essential equipment.But used megameter needs one when ceramic insulator detects at present
The driving switch shift of hand operation instrument, a hand needs to hold probe in detecting insulator, while also needing the disk that watches the instruments
It reads data and records related data, the risk for thering is certain senior middle school to fall, and it was found that when underproof insulator, acquiring
In the work of photo, due to needing both hands to work to operate megameter, the working efficiency of the part is extremely influenced, is added
The clip of the ground terminal of upper megameter used at present is easy to fall off during measurement, is easy to cause measurement data invalid, is needed
From new measurement, waste of manpower keeps its operation especially inconvenient, causes operating efficiency low, there are corresponding falling from high altitude risks.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of facilitate and operates and facilitate and record its insulator state
Portable megameter.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of portable megameter, two probes including body and for detecting insulator, the probe are located at machine
Body the same side and distance are not less than the length of single insulator, and the probe includes rod set and the body of rod, the rod set and the body of rod
Socket forms retractable structure, and the spring being electrically connected for separating probe with body is equipped between the probe and body, described
Body is equipped with hand-held part, and the display screen for observed reading is additionally provided on the body.
Further, the rod set is equipped with the abutting bolt for limiting body of rod sliding.Bar is pushed against by pushing against bolt
Body enables rod set arbitrarily to elongate or shorten in adjustable extent with the body of rod.
Further, the alarm modules when the tested unqualified alarm of insulator are equipped in shown body.It in this way can be square
Just it detects, while being prompted by way of alarm, facilitate record.
The utility model compared with prior art, has the advantages that
By the way that the whole body to be transformed, keep its easy to operate, easy to carry, while the megameter is not necessarily to while using both hands
Probe is positioned, only need to be hold by one hand hand-held part, body probe alignment insulator firmly heads into probe in body,
Body inner looping is connected, detection work can be completed, have many advantages, such as small in size, light-weight.And at the same time when reducing work
Consumption improves whole work efficiency, reduces operating risk, it is ensured that personal safety reduces falling object from high altitude.

Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
Embodiment
As shown in Figure 1, a kind of portable megameter, two probes 2 including body 1 and for detecting insulator are visited
Needle 2 is located at 1 the same side of body and distance is not less than the length of single insulator, and probe 2 includes rod set 21 and the body of rod 22, rod set
21 form retractable structure with the socket of the body of rod 22, are equipped between probe 2 and body 1 and are electrically connected with body 1 for separating probe 2
Spring (does not illustrate) in figure, so that needing probe 2 to be firmly pressed into a bit to quasi-insulator, make it when measurement
Circuit communication, can just measure, and can effectively prevent to contact by mistake in this way causes the numerical value of measurement to change, and influence to record.Machine
Body 1 is equipped with hand-held part 12, so that staff can be hold by one hand, it is not necessary to which both hands operate, and are additionally provided on body 1 and read for observing
Several display screens 11.
Screw hole 23 is offered in the rod set 21 of probe 2 and is screwed with and pushes against bolt (not illustrating in figure), is pushed against bolt and is used
In after 2 adjustment length of probe, pushing against the internal body of rod 22, its length is fixed, so that when being detected, it will not be due to this
Stretching structure interferes probe 2 to head into 1 inside connected loop of body.End of the body of rod 22 far from body 1, is designed, favorably for bulb
In measurement when, for adapting to the abutting contact of different angle.Such as need dumper body 1 to insulator measure when
It waits, it can be by adjusting 2 length of probe, making it, one is long and the other is short, and cooperation holds angle, carries out touching to it using bulb and compresses inspection
It surveys.
Inside body 1, it is additionally provided with alarm modules (not illustrating in figure).Detection for insulator, in the prior art
In due to can just be learnt after can only being checked by reading data, staff its qualifying whether, and this meter by be added alarm
Module when that is, resistance value is lower than 500M Ω, issues buzzing alarm, when detecting that insulator is failed to remind work
Make personnel, enables record more convenient, reduce worker workload, improve working efficiency.
When in use, the length of probe 2 is adjusted according to the radius for being tested insulator first.Adjust spy
After 2 length of needle, probe 2 is directed to the bulb and bowl head of insulator to be detected, then slightly firmly pressing body 1, make probe 2 with
Body 1 is electrically connected, and enables circuit communication, and after one to two seconds, data can be shown on display screen 11, then need to only be read
Complete record.It if the insulator resistance value of meter detection is lower than 500M Ω, will start alarm modules, issue buzzing alarm,
Staff is reminded, record is facilitated.
For above-described embodiment simply to illustrate that the technical ideas and features of the present invention, its purpose is allows this field
Interior those of ordinary skill can understand the content of the utility model and implement accordingly, can not limit the utility model with this
Protection scope.The equivalent changes or modifications that all essence according to the content of the present invention is made, should all cover in this reality
With in novel protection scope.
