As a result switch element main circuit being switched on or switched off.It is with fuse, thermorelay coordinates and may make up more perfect low of function
Compress switch element, and the earth leakage protective device of this form is most widely used at present.
In vehicular applications, this earth leakage protective device exists not enough as is evident below：
One when being that electrical network truly has ground connection, earth leakage protective device regular event.In this regular event, because electrical network is aging, gas
Environmental change is waited, the action that electrical network generation earth point causes accounts for the overwhelming majority, and because the action that person electric shock causes is then few
Number.It is envisioned that can normal electricity consumption be people the first demand, in order to prevent probability it is extremely low the person get an electric shock injury and
Cause and frequently having a power failure, affect normal production and life cause certainly the worry of people.
Two is that electrical network does not occur ground connection originally, but earth leakage protective device may produce malfunction in a case where：
1) as earth leakage protective device is signal trigger action, then can also produce signal triggering under other electromagnetic interference
Earth leakage protective device action, forms malfunction.
2) when on and off switch combined floodgate power transmission, impact signal can be produced and causes earth leakage protective device malfunction.
3) multiple-limb electric leakage sum can cause malfunction of bypassing the immediate leadership.
4) neutral conductor multiple grounding is likely to result in crossfire malfunction.
It can be seen that, as earth leakage protective device technically there is these probabilities for producing malfunction, earth leakage protective device can be made
The dynamic problem of frequency it is more serious, it is more complicated.
