Description
Technical field
The present invention relates to field of circuit breakers, particularly relate to a kind of protection safety type chopper.
Background technology
The effect of chopper is turned off and connects load circuit, and disengagement failure circuit, and Accident prevention expands, it is ensured that peace
Row for the national games.Low-voltage circuit breaker is the one of chopper, and it has multi-protective function (overload, short circuit, low-voltage protection etc.), moves
The advantages such as work value is adjustable, breaking capacity is high, easy to operate, safe, so being widely used.Low-voltage circuit breaker by operating mechanism,
Contact, protection device (various electrical apparatus release), arc quenching system etc. form.
The main contacts of low-voltage circuit breaker is by manual operation or electric switch-on.After main contacts Guan Bi, free tripping mechanism
Main contacts is locked on closing position.The coil of overcurrent trip and the thermal element of thermal trip are connected with main circuit.Work as electricity
Road is short-circuited or during heavy overload, the armature adhesive of overcurrent trip, makes free tripping mechanism action, and main contacts disconnects main
Circuit.When circuit overloads, the thermal element heating of thermal trip makes to bend on bimetal leaf, promotes free tripping mechanism action.
The effect of chopper is that main contacts flicks, the device disconnected by circuit when circuit occurs overload or short circuit.Open circuit
Operationally, inside has electric arc and produces device, and inside has various gas and produces, and the most usually can be provided with on the top of shell
Passage so that gas is outwards discharged.But the direct result that this way causes is foreign to be easier to enter
The inside of relay so that be contaminated inside relay, serious also can corrode chopper, the use of serious threat chopper
Safety.
Summary of the invention
The present invention is directed to foreign and easily enter the technical problem of enclosure, it is provided that a kind of protection safety type open circuit
Device.
Protection safety type chopper in this programme, including breaker body and shell, breaker body is fixedly mounted on
In shell, shell is provided with top cover, and top cover is by shell clamping, and top cover is provided with bellmouth, and the thin lower end, upper end of bellmouth is big, top
Being provided with baffle plate below lid, be provided with and be connected post between baffle plate with top cover, the two ends of connection post are fixing with baffle plate and top cover respectively to be connected,
Baffle plate is provided with blind hole, is provided with powdered sodium carbonate in blind hole, and baffle surface is covered with non-woven fabrics, is provided with magnetic between non-woven fabrics and baffle plate
Ferrum, Magnet is embedded on baffle plate, and Magnet is positioned at baffle bottom.
Operation principle and the advantage of this programme are as follows: when normally using, the harmful gas meeting produced because of contact folding
Discharging from bellmouth, the foreign body of housing exterior is when contacting with bellmouth, owing to thin lower end, bellmouth upper end is big, and bigger foreign body
Can be blocked by the thinner end of bellmouth, harmful gas, when bellmouth is discharged, first with the bigger end in contact of bellmouth, easily facilitates
Harmful gas is discharged.On the one hand bellmouth stops foreign body, protective breaker body, prevents chopper to be contaminated, the most more
Add beneficially gas to discharge.
The foreign body being entered enclosure by bellmouth can be blocked, on baffle plate in blind hole by the baffle plate below bellmouth
Powdered sodium carbonate can absorb the moisture in air, keeps breaker body to be dried, and sodium carbonate becomes weak base after absorbing moisture
Property, the harmful gas that contact produces because of electric arc in moving process mainly includes nitric acid, metal dust and other gas, weak base
The powdered sodium carbonate of property can neutralize nitric acid.Metal dust can be played adsorption by the Magnet on baffle plate.Non-woven fabrics can
The effect of the dust play the powdered sodium carbonate fixing in blind hole, adsorbing in air.
This programme, by arranging bellmouth, baffle plate and arranging carbonic acid and Magnet on baffle plate, reaches to exhale pernicious gases,
Nitric acid in absorption harmful gas and metal dust, reach the purpose of protective breaker ontological security.
Further, Magnet is provided with screw thread, and Magnet is threadeded with baffle plate.Conveniently Magnet dismantled and install.
Further, a diameter of 0.5-3cm of blind hole.The too small meeting of diameter of blind hole causes the powder of sodium carbonate very few, it is impossible to
Reach to neutralize the effect of nitric acid；The diameter of blind hole is crossed conference and is caused the intensity of baffle plate to decline.
Further, a length of 0.5-3cm of post is connected.The too short meeting of length connecting post causes the harmful gas can not be effective
Discharge；The long meeting of length connecting post takies the space that enclosure is more, is unfavorable for the installation of breaker body.
Further, a diameter of 0.5cm of bellmouth thinner end.In actual applications, the diameter of bellmouth thinner end is too small
It is unfavorable for the discharge of harmful gas；The diameter of bellmouth thinner end is excessive can not play the effect stopping foreign body
Further, a diameter of 3cm of bigger end.The too small eliminating being unfavorable for harmful gas of diameter of the bigger end of bellmouth；Cone
The diameter of the bigger end in shape hole crosses conference affects the intensity of top cover.
Accompanying drawing explanation
Fig. 1 is the structural representation of top cover in the embodiment of the present invention 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference in Figure of description includes: top cover 1, bellmouth 2, baffle plate 3, Magnet 4.
Embodiment 1
The most as shown in Figure 1: protection safety type chopper, including breaker body and shell, breaker body fixedly mounts
In the enclosure, shell is provided with top cover 1, and top cover 1 is by shell clamping, and top cover 1 is provided with bellmouth 2, under the upper end of bellmouth 2 is thin
End is big, a diameter of 0.5cm of bellmouth 2 thinner end, a diameter of 3cm of bigger end, is provided with baffle plate 3 below top cover 1, baffle plate 3 with
Being provided with the connection post of a length of 1cm between top cover 1, the two ends of connection post are fixing with top cover 1 with baffle plate 3 respectively to be connected, on baffle plate 3
Being provided with a diameter of 1cm blind hole, be provided with powdered sodium carbonate in blind hole, baffle plate 3 surface is covered with non-woven fabrics, between non-woven fabrics and baffle plate 3
Being provided with Magnet 4, Magnet 4 is embedded on baffle plate 3, and Magnet 4 is positioned at bottom baffle plate 3.
Time specifically used: the foreign body outside shell is when contacting with bellmouth 2, owing to thin lower end, bellmouth 2 upper end is big, more greatly
Foreign body can be blocked by the thinner end of bellmouth 2, harmful gas is when bellmouth 2 is discharged, first with the bigger termination of bellmouth 2
Touch, easily facilitate harmful gas and discharge.
The foreign body being entered enclosure by bellmouth 2 can be blocked by the baffle plate 3 below bellmouth 2, blind hole on baffle plate 3
Interior powdered sodium carbonate can absorb the moisture in air, keeps breaker body to be dried, and sodium carbonate becomes after absorbing moisture
Alkalescence, the harmful gas that contact produces because of electric arc in moving process mainly includes nitric acid, metal dust and other gas,
Weakly alkaline powdered sodium carbonate can neutralize nitric acid.Metal dust can be played adsorption by the Magnet 4 on baffle plate 3.
