User can be disconnected or be closed manually by way of pulling the second operation handle 241 and the first operation handle 141
The operation of second switch mechanism and first switch mechanism is closed, specifically, the second operation handle 241 and the first operation handle 141 pendulum
It is dynamic to make that the second swing arm 242 and the first swing arm 142 be driven to swing respectively by second connecting rod 246 and first connecting rod 146, subsequent the
Two swing arms 242 and the first swing arm 142 drive the second contact and the first moving contact 143 to swing to realize second switch mechanism respectively
With first switch mechanism break-make, and the second swing arm 242 and second lock 245 between and the first swing arm 142 and first lock 145
Between by be clamped lock, the state for making second switch mechanism and first switch mechanism remain open or be closed.
When second switch mechanism is closed, 23 electricity of the second main traverse line in second switch box 2 is powered and by the second induction
Coil 252 generates electromagnetic induction outside the second short-circuit magnetictrip 251, forms certain magnetic field, it is generated under normal circumstances
Magnetic field be not enough to the second short-circuit magnetictrip 251 of driving and carry out contraction dropout, when 2 short circuit of second switch box, its electric current increases
Adding, which makes the second induction coil 252 generate sufficiently large magnetic field, makes the second short-circuit magnetictrip 251 shrink dropout, i.e., the second short circuit
Magnetictrip 251, which is shunk, drives the second moving contact 243 to swing to disconnect.When first switch mechanism is closed, first
13 electricity of the first main traverse line in switch enclosure 1 is powered and is produced outside the first short-circuit magnetictrip 151 by the first induction coil 152
Raw electromagnetic induction, forms certain magnetic field, its magnetic field generated is not enough to the short-circuit magnetictrip of driving first under normal circumstances
151 carry out contraction dropout, when the short circuit of first switch box 1 its electric current increase so that the first induction coil 152 is generated sufficiently large magnetic
Field makes the first short-circuit magnetictrip 151 shrink dropout, i.e., the first short-circuit magnetictrip 151, which is shunk, drives the first moving contact
143 swing to disconnect.
After second switch box 2 and first switch box 1 are separately connected zero curve and firewire, the second main traverse line 23 and first master
The circulation of conducting wire 13 has reverse current, and the induced field generated in mutual inductor 261 is cancelled out each other, therefore mutual inductor 261 does not produce
Raw induced current, earth leakage protective magnetictrip 263, which does not work, keeps second switch mechanism and first switch mechanism to be closed.When going out
When the case where now leaking electricity, the one of which short circuit in the second main traverse line 23 or the first main traverse line 13 causes it not have electric current to pass through,
The electric current of another one normally circulates and mutual inductor 261 is made to generate induced current, and the induced current of production passes through power amplifier
Driving earth leakage protective magnetictrip 263, which is shunk, after 262 amplifications threads off, and disconnects second switch mechanism and first switch mechanism.
The embodiment of the above is only presently preferred embodiments of the present invention, not does limit in any form to the present invention
System.Any technical person familiar with the field, without departing from the scope of the technical proposal of the invention, all using the disclosure above
Technology contents more possible variations and retouching are made to technical solution of the present invention, or be revised as the equivalence enforcement of equivalent variations
