Abstract
The utility model relates to an arc barrier chamber of a circuit breaker. The arc barrier chamber comprises an arc barrier chamber body made from an insulating material, arc extinguishing meshes and detachable baffles. The arc barrier chamber is mounted outside the contacts of wiring terminals of the circuit breaker and fully covers the wiring terminals. The arc barrier chamber of the circuit breaker has enhanced insulativity and high security, prolongs the service life of the circuit breaker and protects the personnel safety of operators. For a front-board wiring circuit breaker, the grid baffles at the lower part of the arc barrier chamber can be directly detached to facilitate secondary wiring; and for a rear-board wiring circuit breaker, functions of attractiveness and safety can be served.
Description
Technical field
The utility model relates to the low-pressure electronic equipment product field, especially circuit breaker arc cover.
Background technology
The high heat that produces during the low-voltage circuit breaker disjunction makes in the contact cavities and forms very high draught head with the external world, and intracavity gas can outwards spray along the slit, contains electric arc in the gas of injection.On the body of general circuit breaker arc control device are installed, arc control device contain many slits, are the outwards main thoroughfares of discharging of contact intracavity gas, and the arc control device next door is provided with the injection end shield that is used for preventing arcing, and the end shield space is big.In general; The arc energy that rational project organization should reach the circuit breaker generation all is introduced in the arc extinguishing structure in the arc control device; It is eliminated fully, the safe gas of only remaining high temperature, high pressure, safe gas is discharged through end shield safety then; Each parts of realization isostasy and protective circuit breaker are avoided damaging, protection operator's personal safety.
Be directed to the best withdrawable circuit breaker of present antiarcing-over effect especially, its end shield is installed on the drawer, and arc control device are installed on the breaker body; Body and drawer can be realized split operation, but during the withdrawable circuit breaker operate as normal, body is inner at drawout chassis; Breaker body is movable between end shield and the arc control device, has certain interval between end shield and the arc control device, so that can not be touched when getting into drawout chassis; When the circuit breaker disjunction, electric arc that can produce and thermal current, thermal current have very strong impulsive force; Part thermal current still can be carried some metallics and the impurity gap ejection arc control device through depositing between end shield and the arc control device secretly; Might make the inner electric conductor connection of circuit breaker and charged, and because the big influence of air pressure, charged particle also can be discharged from above-mentioned gap; Be injected in around the breaker body, can cause serious phase fault and ground fault; In addition, also can cause the certain device loss, and operating personnel are caused certain personal injury circuit breaker itself.Certainly, also there is identical problem in the circuit breaker of other kinds.
Summary of the invention
The utility model technical problem to be solved is that the existing circuit breaker arc insulating apparatus is difficult to effective protective circuit breaker equipment, has potential safety hazard; And a kind of circuit breaker arc cover is provided, this arc cover effectively protective circuit breaker equipment, guarantee that device security normally uses, makes things convenient for wiring and reduces personal safety constituted a threat to.
The utility model is achieved in the following manner:
Circuit breaker arc cover; Said circuit breaker arc cover is installed on the outside of breaker connection terminal contact and covers said binding post contact, and said circuit breaker arc cover comprises: arc cover body, through the embedded a plurality of baffle plates that are buckled in a plurality of arc extinguishing net sheets on said arc cover body top and are removably disposed in said arc cover body bottom.
In the above-mentioned arc cover, the position that said arc cover body is installed said arc extinguishing net sheet is an engraved structure.
In the above-mentioned arc cover, have a plurality of reticulated cell on the said arc extinguishing net sheet.
In the above-mentioned arc cover, also be provided with Elastic buckle spare on the said arc cover body, said circuit breaker arc cover is through said Elastic buckle spare and breaker body clamping.
In the above-mentioned arc cover, said arc extinguishing net sheet and said baffle plate are three.
In the above-mentioned arc cover, said baffle plate is the grid baffle plate.
The utility model has been realized the isolation of internal environment of each element of inside and the circuit breaker of circuit breaker top arc control device and breaker body; When disjunction appears in circuit breaker; It is inner that this structure can effectively stop residue high temperature and high pressure gas or charged particle to get into breaker body; Can realize the secondary arc extinguishing, prevent that it from producing harmful effect and other damages or danger to the circuit breaker inner member, can improve the fail safe of operating personnel's operation simultaneously greatly; Simultaneously on the arc cover dismountable baffle plate is set, for preceding wiring, below the arc cover to delete the lattice baffle plate directly detachable; Wiring behind the plate, the grid baffle plate is just directly being put, and plays attractive in appearance, safe effect.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the circuit breaker arc cover front view of the utility model;
Fig. 2 be among Fig. 1 A-A ' to cutaway view.
Embodiment
Extremely shown in Figure 2 like Fig. 1; The utility model discloses: circuit breaker arc cover; Said circuit breaker arc cover is installed on the outside of breaker connection terminal contact and covers said binding post contact, and said circuit breaker arc cover comprises: arc cover body 1, through the embedded a plurality of baffle plates 3 that are buckled in a plurality of arc extinguishing net sheets 2 on said arc cover body 1 top and are removably disposed in said arc cover body 1 bottom.The position that said arc cover body 1 is installed said arc extinguishing net sheet 2 is an engraved structure.Have a plurality of reticulated cell on the said arc extinguishing net sheet 2.Also be provided with Elastic buckle spare on the said arc cover body 1, said circuit breaker arc cover is through said Elastic buckle spare and breaker body clamping.Said arc extinguishing net sheet 2 is three with said baffle plate 3.Said baffle plate 3 is the grid baffle plate.
Said circuit breaker arc covers on when installing and is buckled on the breaker body; Said arc extinguishing net sheet 2 is located at the position corresponding with the arc control device of breaker body; Carry out the secondary arc extinguishing through said arc extinguishing net sheet 2 time from the arcing of arc control device and other directions; Guarantee the operate as normal of circuit breaker and operating personnel's life safety, and this arc insulating apparatus carries out the buckle connection with breaker body, easier for installation, saving cost.
The preceding wiring of plate for ease simultaneously is provided with on this arc insulating apparatus with the corresponding dismountable said baffle plate 3 in binding post position, when carrying out breaker connection, installs after can directly said baffle plate 3 being removed again.
The foregoing description only is used to explain the usefulness of the utility model; It is not restriction to the utility model; Under the guidance of the utility model connotation, also can make corresponding distortion and modification, so all technical schemes that are equal to all belong to the protection category of the utility model.
