Description
Technical field
The utility model is related to the works that the technical field of power plant production O＆M more particularly to a kind of main transformer survey insulation
Tool.
Background technology
The mode that power plant main transformer surveys insulation now is that staff carries measuring appliance and reaches transformer through walking ladder
Top carries out insulation measurement, and there are many security risks for this method.There is more than 5m on main transformer distance from top ground, and space is narrow
It is small, it is unfavorable for using of seat belts and safety rope, survey crew will also face survey not only it is noted that Equilibrium prevents from falling
Amount Work tool is nowhere put, avoids the unrelated position of touching transformer, turns round the problems such as difficulty, difficulty in walking.And up to one minute
Time of measuring, limited by human body patience, it is difficult to ensure that the cmpletely contact of measuring point, if happening sleety weather,
Ponding on cat ladder falls snow or icing or even to climb up transformer top all highly difficult.
The content of the invention
The defects of to overcome the prior art, the technical problem to be solved by the present invention is to provide a kind of surveys of main transformer
The instrument of insulation, can make measurement end be connected to the survey insulating megger on ground through wire clamp, conducting wire, and survey crew can stand
Survey insulated working is carried out on the ground.
The technical solution of the utility model is：This main transformer surveys the instrument of insulation, including：Wire clamp (1), measurement are led
Line (2), insulating bar (3) survey insulating megger (4), and wire clamp (1) is mounted on one end of measure traverse line (2), survey insulating megger (4) even
The other end of measure traverse line (2) is connected on, measure traverse line (2) is placed on insulating bar (3), and wire clamp hangs over main transformer and goes out when surveying insulation
At mouthful.
In this way, measurement end is connected to the survey insulating megger on ground through wire clamp, conducting wire, survey crew can be at station on ground
On carry out survey insulated working.Because without climbing up transformer, the danger of falling from high altitude is prevented.Ground space is sufficient,
It nowhere put there is no previous measurement Work tool, touch the unrelated position of transformer, turn round the problems such as difficulty, difficulty in walking.Cause
It is that direct folder hangs over high (low) the pressure side outlet measured place of transformer for wire clamp, need not artificially for a long time withstands on measure traverse line
Transformer measured place, therefore limited from human body patience, it can be ensured that it is abundant, firm that measurement portion tap is touched.Along with this method
It is easy to operate, so as to overcome this technical barrier.This new survey insulating method, coordinates corresponding tool innovation, evades
The risk of working at height, simplifies work difficulty, eliminates and surveys the person, equipment safety hidden danger present in insulation process, it is ensured that
Personal safety and equipment safety have the value promoted the use of.
Description of the drawings
Fig. 1 is the structure diagram for the instrument that main transformer according to the present invention surveys insulation.
Specific embodiment
As shown in Figure 1, this main transformer surveys the instrument of insulation, including：Wire clamp 1, measure traverse line 2, insulating bar 3, survey
Insulating megger 4, wire clamp 1 are mounted on one end of measure traverse line 2, survey the other end that insulating megger 4 is connected to measure traverse line 2, measurement
Conducting wire 2 is placed on insulating bar 3, and wire clamp is hung at main transformer outlet when surveying insulation.
In this way, measurement end is connected to the survey insulating megger on ground through wire clamp, conducting wire, survey crew can be at station on ground
On carry out survey insulated working.Because without climbing up transformer, the danger of falling from high altitude is prevented.Ground space is sufficient,
It nowhere put there is no previous measurement Work tool, touch the unrelated position of transformer, turn round the problems such as difficulty, difficulty in walking.Cause
It is that direct folder hangs over high (low) the pressure side outlet measured place of transformer for wire clamp, need not artificially for a long time withstands on measure traverse line
Transformer measured place, therefore limited from human body patience, it can be ensured that it is abundant, firm that measurement portion tap is touched.Along with this method
It is easy to operate, so as to overcome this technical barrier.This new survey insulating method, coordinates corresponding tool innovation, evades
The risk of working at height, simplifies work difficulty, eliminates and surveys the person, equipment safety hidden danger present in insulation process, it is ensured that
Personal safety and equipment safety have the value promoted the use of.
Preferably, the first half of the wire clamp is inverted U, and wire clamp is more easily made to hang over the measured place of transformer.
Preferably, the lower half of the wire clamp 1 is cylindrical type handle, more easily can operate wire clamp with insulating bar.
Preferably, there is the sheet metal of two panels band elasticity inside the first half of the wire clamp 1, be more convenient wire clamp and transformer
Measured place is fixed.
Preferably, the two panels sheet metal is into splayed configuration, the two panels sheet metal it is close to each other in the bottom of the inverted U and
It is located remotely from each other on the top of the inverted U, when the inverted U is hung at main transformer outlet, which blocks master
Cable at transformer outlet.So ensure that measurement portion tap is touched fully, it is firm.
Preferably, the wire clamp is metal, and the insulating bar is plastics.
The utility model is for practice in factory, through repeatedly testing and summarizing relevant historical experience, proposes to survey exhausted
The place of edge is changed to this innovation idea of ground by transformer top.It is such to change the peace for fundamentally having evaded working at height
Full hidden danger, but new technical barrier is also brought simultaneously：Transformer is not climbed up, how to allow high (low) pressure of measure traverse line and transformer
Side outlet measured place keeps contactIn order to solve this problem, a large amount of field conditions are carried out and have reconnoitred, research is determined using as follows
Method:Wire clamp is installed in one end of measure traverse line, one end that measure traverse line has wire clamp on ground using insulating bar is pressed from both sides and hung by people station
In the measured place of transformer, the conducting wire other end is connected to survey insulating megger.In this way, measurement end is connected to ground through wire clamp, conducting wire
Survey insulating megger, survey crew can station carry out survey insulated working on the ground.Because without climbing up transformer,
The danger of falling from high altitude is prevented.Ground space is sufficient, will not have previous measurement Work tool and nowhere put, touches transformer
The problems such as difficulty, difficulty in walking, is turned round at unrelated position.High (low) the pressure side outlet measurement of transformer is hung over because wire clamp is direct folder
Place, need not measure traverse line artificially be withstood on into transformer measured place for a long time, therefore be limited from human body patience, it can be ensured that surveyed
It is abundant, firm that amount part contacts.Along with this method is easy to operate, so as to overcome this technical barrier.This new survey
Insulating method coordinates corresponding tool innovation, has evaded the risk of working at height, has simplified work difficulty, eliminates survey insulation
The existing person, equipment safety hidden danger in the process, it is ensured that personal safety and equipment safety have the value promoted the use of.
The above is only the preferred embodiment of the utility model, not makees limit in any form to the utility model
System, every any simple modification, equivalent change and modification made according to the technical essence of the utility model to above example,
Still belong to the protection domain of technical solutions of the utility model.
