Member's injures and deaths.
According to the regulation of GB4706.1-2005 standard, the measurement of leakage current power supply any pole with connect metal foil
Easily touch between metal parts and carry out.In actual monitoring work, the connection between measuring instrumentss and electric appliance mostly uses clip
The mode being clipped on exposed component is realized, it is difficult to guarantee the reliable of connection, while there is also the risks of electric shock.
Summary of the invention
The utility model in order to make up for the deficiencies of the prior art, provides that a kind of structure is simple, household electric easy to use
Device working condition leakage current testing box.
The utility model is achieved by the following technical solution:
The household electric appliance operation state leakage current testing cassete of the utility model, it is characterised in that: including shell, Yi Jifen
Power input socket on the shell or plug, power output socket, ground line on-off switch and measurement terminal, shell are not installed
There is connecting line in inside；L, N line of power input socket or plug and power output socket are connected respectively, and power input
L, N line of socket or plug are connected in L, N line corresponding end of measurement terminal, and the ground wire G of power input socket or plug passes through
It is connected respectively on the ground terminal of power output socket and the ground terminal of measurement terminal after ground line on-off switch.
Shell, which is adopted, to be made from an insulative material, power input socket or plug, power output socket, ground line on-off switch and
Measurement terminal is separately mounted to left side, right side, front, the rear portion of shell.
Power input socket or plug: single-phase input socket with ground is used, for connecting to power supply；
Power output socket: it for being connect with tested equipment, powers to equipment under test, using 5 spring hole scokets, can connect
Single-phase grounded plug and single-phase not grounded plug；

Measurement terminal: using having insulation sheath formula banana connector, and the convenient test pencil with measuring instrumentss is attached, simultaneously
Preferable insulating protection is provided.
Measuring instrumentss use leakage current tester.
The utility model has the beneficial effects that
1. itself leakage current of the leakage current testing box is extremely low, connect using input socket, output socket, plug-in type measurement
Mouthful the connection of measuring circuit is completed, realization is reliably connected, and eliminates the Danger Electric shock risk of tester, substantially increase measurement essence
Degree.
2. being measured by measuring box connection, connection is simple, reduces the complexity of measurement process, reduces workload,
Improve working efficiency.
3. measuring instrument connection, convenient and fast connection, safe and reliable, test using insulating sheath formula banana connector
Circuit package improves the safety of detection work in cassette interior.
4. using 5 hole output sockets can be convenient connection it is with ground or not with ground by electricity measurer, it is not necessary in addition plus
Fill multi-tap.
5. reducing the elements such as selection switch, the measurement of not homopolarity is carried out by the way of jack combination, although not as good as using
Selection switch is convenient and efficient, but leakage current caused by measuring box being greatly reduced itself, improves measurement accuracy.
