Description
Technical field
Electrical apparatus release auxiliary switch is the utility model is related to, more particularly to a kind of standby SPD disconnectors.
Background technology
At present, the tripping mechanism in disconnector is all made of metal material, during use around electricity to grow field too big, easily by mistake
It is dynamic, cause to switch early jump, and also service life is short, and arc quenching effect is poor, and original tripping coil is connected to the upper end of leading-out terminal, when big
Electric current by when easy sound give birth to malfunction, so needing a kind of standby SPD disconnectors to solve these problems.
Utility model content
For existing technical deficiency, the utility model provides a kind of standby SPD disconnectors.
To achieve these goals, technical solution adopted in the utility model is：A kind of standby SPD disconnectors, including
Shell, described shell is interior to be provided with tripping mechanism, electric coil, arc-extinguishing mechanism and terminals, and described terminals set outer respectively
Shell both sides, in addition to handle, described handle are linked with tripping mechanism by gangbar, and described tripping mechanism is provided with
Moving contact, described electric coil are provided with static contact, and the position that described moving contact contacts with static contact is provided with through-flow body, works as hand
During motion of handle, handle drives tripping mechanism motion, and the moving contact of tripping mechanism is contacted by through-flow body with the static contact of electric coil,
Described tripping mechanism is connected with a side terminal by wire, and the leading-out terminal lower end of another side terminal is with electric coil by leading
Line connects, and described arc-extinguishing mechanism is arranged on the static contact of electric coil and the moving contact junction lower end of tripping mechanism, in addition to
Discharge tube, described discharge tube connects static contact by wire and terminals, described tripping mechanism are made up of plastic material.
Described arc-extinguishing mechanism includes arc-extinguish chamber and arc striking piece, arc striking piece one end and the terminal contact for being connected tripping mechanism
It is powered.
The contact area of described static contact is consistent with through-flow bulk area.
The beneficial effects of the utility model：The utility model provides a kind of standby SPD disconnectors, the tripping mechanism of this product
Being reduced using current field after plastic material, do not allow easy malfunction, the coil of this product is connected to the leading-out terminal lower end of terminals, when
After high current is absorbed by discharge tube, this external disengaging is not in false tripping, makes lightningproof all the time in effective
State, and service life is grown, and arc quenching effect is good, practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, a kind of standby SPD disconnectors, including shell 1, described shell 1 is interior to be provided with tripping mechanism 2, electric wire
Circle 3, arc-extinguishing mechanism and terminals 4, described terminals 4 set the both sides of shell 1, in addition to handle 5, described handle 5 respectively
It is linked with tripping mechanism 2 by gangbar 6, described tripping mechanism 2 is provided with moving contact 21, on described electric coil 3
Provided with static contact 31, the position that described moving contact 21 contacts with static contact 31 is provided with through-flow body 7, when handle 5 moves, handle
5 drive tripping mechanisms 2 are moved, and the moving contact 21 of tripping mechanism 2 is contacted by through-flow body 7 with the static contact 31 of electric coil 3, described
Tripping mechanism 2 be connected with a side terminal 4 by wire, the lower end of leading-out terminal 41 and the electric coil 3 of another side terminal 4 pass through
Wire is connected, and described arc-extinguishing mechanism is arranged under the static contact 31 of electric coil 3 and the junction of moving contact 21 of tripping mechanism 2
End, in addition to discharge tube 8, described discharge tube 8 connects static contact 31 by wire and terminals 4, described tripping mechanism 2 are
Plastic material is made, and adds through-flow body, and originally operating will wear for five times or so, after improvement 20 times it is all out of question,
Described arc-extinguishing mechanism includes arc-extinguish chamber 9 and arc striking piece 10, the one end of arc striking piece 9 and the wiring for being connected tripping mechanism 2
The contact of end 4 is powered, and original arc extinguishing enclosure volume is excessive, small volume and arc quenching effect is more preferable after improvement.
The contact area of described static contact 31 is consistent with the through-flow area of body 7, and the surface of static contact 31 increases, and bears through-flow increasing
Greatly.
The beneficial effects of the utility model：The utility model provides a kind of standby SPD disconnectors, the tripping mechanism of this product
Being reduced using current field after plastic material, do not allow easy malfunction, the coil of this product is connected to the leading-out terminal lower end of terminals, when
After high current is absorbed by discharge tube, this external disengaging is not in false tripping, makes lightningproof all the time in effective
State, and service life is grown, and arc quenching effect is good, practical.
