Abstract
The utility model relates to a modular dipolar vertical combined air switch. In a casing 1, a live wire wiring port 10 is electrically connected with an arc extinguishing radiation device 8 and a live wire main contact 2. A switch handle 13 is connected with a crank arm 4. An overloading protection induction device 7 for over-current and over-voltage is electrically connected with a live wire conductive body 6. A pulse signal output interface 9 is electrically connected with the conductive body 6. A zero wire wiring port 11 is electrically connected with a magnetic keeping zero wire auxiliary contact 3. A deflector rod 5 is arranged between the crank arm 4 and the magnetic keeping zero wire auxiliary contact 3.
Description
Affiliated technical field
The utility model relates to a kind of overcurrent-overvoltage excess load Protector for using electricity, especially under the situation of overcurrent-overvoltage excess load electricity consumption, can disconnect modular two utmost point Vertical Combination air switches of live wire and zero line simultaneously.
Background technology
At present, known two utmost point air switches all are horizontal positioned, the closure of zero line is decision by the up and down of live wire switch knob, and this switch is that the shell by two single-pole switchs combines, and plants oneself excessive and can not satisfy the needs of different user fully.
Summary of the invention
In order to overcome the needs of excessive deficiency of existing two utmost point air switch volumes and adaptation different user, the utility model provides a kind of needs that can satisfy different user, again can be manually or disconnect two utmost point Vertical Combination air switches of live wire and zero line simultaneously under the overcurrent-overvoltage overload condition.
The technical scheme that its technical problem that solves the utility model adopts is: an end of the top hot terminal mouth 10 of housing 1 and arc extinguishing heat abstractor 8 are for being electrically connected; the other end of hot terminal mouth 10 and live wire main contact 2 are for being electrically connected; switch knob 13 is connected with connecting lever 4; overcurrent-overvoltage excess load protection induction installation 7 and live wire electric conductor 6 are for being electrically connected; pulse signal output interface 9 and live wire electric conductor 6 be for being electrically connected, and ramp 12 and hot terminal mouth 10 are for being electrically connected.Keep zero line secondary contact 3 for being electrically connected at the bottom of housing 1 zero line Wiring port 11 and magnetic, ramp 12 and zero line Wiring port 11 are provided with driving lever 5 for being electrically connected between connecting lever 4 and magnetic maintenance zero line secondary contact.Live wire electric conductor 6 is made up of splitter, and hot terminal mouth 10 and zero line Wiring port 11 are respectively upper and lower settings.
The beneficial effects of the utility model are: 1, hot terminal mouth and zero line Wiring port are upper and lower settings, have overcome the existing two utmost point combination air switch horizontal positioned big shortcoming that plants oneself.2, the live wire electric conductor in modular two utmost point Vertical Combination air switches is made up of splitter, has fully used the resource of electric conductor, has saved raw material, has the electric pulse signal output interface, has increased the function of use of air switch.
Description of drawings
Among the figure 1, housing 2, live wire main contact 3, magnetic keep zero line secondary contact 4, connecting lever 5, driving lever 6, live wire electric conductor 7, overcurrent-overvoltage excess load protection induction installation 8, arc extinguishing heat abstractor 9, pulse signal output interface 10, hot terminal mouth 11, zero line terminals 12, ramp 13, switch knob
Embodiment
The course of work of the present utility model and principle are: the outer switch knob 13 of housing is pushed the enable possition to, handle 13 spurs the interior connecting lever 4 of housings on the one hand, one end perk of connecting lever 4, the pull bar that drives overcurrent-overvoltage excess load protection induction installation 7 is in stretch position, it is in treats operating state, the live wire main contact 2 on the connecting lever 4 touches with electric conductor 6 and closes simultaneously; Connecting lever 4 is stirred the driving lever 5 that magnetic keeps zero line secondary contact 3 on the other hand, makes magnetic keep zero line secondary contact 3 and electric conductor 6 to be in attracting state.Otherwise, the outer switch knob 13 of housing is pushed off-position to, connecting lever 4 in the handle 13 pulling housings, one end of connecting lever 4 resets, live wire main contact 2 on the connecting lever 4 disconnects with electric conductor 6 on the one hand, connecting lever 4 drives magnetic maintenance zero line secondary contact driving lever 5 on the other hand, makes magnetic keep zero line secondary contact 3 to separate with electric conductor 6.When touching, closes live wire main contact 2; overcurrent-overvoltage excess load protection induction installation 7 is in treats operating state; during excess load; its pull bar bounces back automatically; on the one hand and drive connecting lever 4 and reset; live wire main contact 2 is separated with electric conductor 6, and connecting lever 4 drives switch knobs 13 driving lever 5 that resets simultaneously and drives magnetic and keep zero line secondary contacts 3 to separate with electric conductor 6 in the lump on the other hand.
