Fig. 2 is the scheme of installation of power taking component, drum and conductor cable.
Embodiment
It is below in conjunction with the accompanying drawings and specific real in order to be more clearly understood that the above objects, features and advantages of the present invention
Apply mode and make further nonrestrictive detailed description to technical solution of the present invention.
See Fig. 1 and Fig. 2：
The 10kV aerial lift device with insulating arm for live working Leakage Currents monitoring device of the present embodiment mainly include power taking component 100,
Conductor cable 200 and Leakage Current detector (not shown), power taking component therein are used to obtain its leakage from insulation arm
Electric current, conductor cable are used to electric current being guided to Leakage Current detector, and Leakage Current detector is Data Collection and measurement member
Part.Its general principles is：Power taking component does mobile monitoring on insulation arm, is delivered current to by conductor cable under arm
End, Leakage Current detector is introduced, form all the period of time digital independent.
Power taking component includes base 1, rotary shaft electric conductor 2 and telescopic electric conductor 3.Base is by insulated nylon material system
Make, be screwed on the metal arm 300 of Live working Aerial Device.Rotary shaft electric conductor 2 is fixedly mounted on base, this implementation
Rotary shaft electric conductor is reequiped by travel switch, and the rotating shaft of travel switch is as input electrode, telescopic electric conductor and its electricity
Connection, one of contact of travel switch are electric with conductor cable as output electrode, the contact and the normally closed conjunction of rotating shaft, while again
Connection.Telescopic electric conductor 3 is a metalwork with Telescopic, and its Telescopic can use spring to realize that this is stretched
Contracting formula electric conductor be arranged on rotary shaft electric conductor on, can be rotated with its rotating shaft, the telescopic electric conductor also with Live working Aerial Device
Insulation arm 400 be in contact.
The major function of power taking component is is kept for all the period of time to insulation arm insulated part contact, i.e., no matter insulation arm does and stretched
Contracting motion or radial motion, power taking point close contact, while will not cause to damage to insulation arm body all the time.
Conductor cable is arranged in drum 4, is reclaimed inside drum using memory spring to releasing conductor cable, drum
It is placed on the panel of vehicle insulation arm rotary shaft base side.Conductor cable is used to be conducted electricity mainly to provide cable to power taking point
Transmit, while man-hour rotation and circuit radial direction folding and unfolding action are carried out with work jibs, avoid cable from touching other powered conductor wires

The Leakage Current monitor of the present embodiment is a kind of made in U.S.A exclusively with mutually exhausted to measure band in electrical wiring
Between the metal parts of edge, or between electrical accessory and grounding body, pass through the full man-hour of its surrounding medium or insulating surface electric current
Instrument, the instrument can be assemblied in exposure (nature) environment, be the Data Collection and measuring cell of apparatus of the present invention.
2017, collaboration Southern Power Grid Company DianKeYuan in livewire work center carried out tests below and has carried out data point
Analysis, to check the accuracy of the device, that is, is analyzed as follows：
Table 1：When insulation arm stretches out 1.2m, upper arm+oil pipe is over the ground (vehicle)
Table 2：Insulation arm stretches out to be grounded at 1.2m, and upper arm+oil pipe is over the ground
What it is because of standard amperemeters detection is to face earth-current, and what Leakage Current monitor detected is point to earth-current.According to
Test data, the first test method phase difference data are about 7 times, and second of test method phase difference data is about 6 times,
So initial analysis is drawn a conclusion：According to the rise of test voltage, Leakage Current synchronously rises and linearly changed, normalized current
Reading data between table and Leakage Current monitor are in fixed multiple proportion.
According to《Distribution line live working technology and management》Power distribution live-wire overhead insulation bucket arm vehicle electricity in guidance
