Description
Technical field
The utility model belongs to electric protective device field more particularly to a kind of breaker arc light isolation cover.
Background technology
In oil-field electric system, breaker is a kind of common circuit devcie, and breaker can generate arc light when disconnecting,
The size of arc light is related with power supply capacity and load running situation, when disconnecting big load, when arc light exceeds breaker arc extinguishing ability
It can overflow, the spilling of arc light easily causes power supply short circuit accident, so present breaker is substantially made using two partition plates
For arc light quarantine measures.But two pieces of partition plates are only installed, and busbar does not make insulation measures, when breaker is because instantaneously rapidly on breaker
When overload or load short circuits trip, powerful arc light is generated, isolated gate cannot play arc light buffer action completely, in reality
Often occur the major accidents such as power failure, halt production and burning apparatus caused by arc short-circuit during use, using isolated gate
Arc light quarantine measures have been unable to meet needs of production, and there are security risks.
The content of the invention
The utility model provides a kind of breaker arc light isolation cover, to solve the problems mentioned in the above background technology.
The technical issues of the utility model solves is realized using following technical scheme：The utility model provides one kind
Breaker arc light isolation cover is square structure including four pieces of risers, three pieces of arc panels and three lacing wires, riser, each riser etc.
Spacing is arranged in parallel, and is fixed between adjacent two pieces of risers by one piece of arc panel and a lacing wire connection, arc panel and lacing wire
Riser is each perpendicular to, arc panel is projected as zhou duicheng tuxing on riser, and symmetry axis is overlapped with a diagonal of riser,
The lacing wire is arranged on the inside of arc panel, the edge of the riser leave for by riser plugged and fixed on-board the circuit breaker
Plug division, the riser, arc panel and lacing wire are made of flame retardant rubber.
The outer edge of the lacing wire aligns respectively with two edges of arc panel.The flame retardant rubber gathers for chlorosulfonation
Ethylene.
The beneficial effects of the utility model are：
1st, the utility model designed and produced one with the size shape of breaker it is matched, can be with carrying on breaker
It is that bar-shaped trough grafting is connected, can by breaker three-phase arc light export isolate, can change arc light emission direction arc light isolation
Device, it is simple in structure, easy for installation, arc light isolation effect is good, and can effectively avoid arc light and injure busbar.
2nd, the utility model uses the rubber insulation material with fire retardation, avoids by the high temperature scaling loss of arc light.In addition,
Rubber insulation material is cheap, and difficulty of processing is small, and due to being made of insulating materials, not having a power failure can install, i.e., do not influence
Production, installation and particularly convenient safety.
3rd, coordinated closely by the utility model and breaker size, can realize the isolation of arc light completely, it can maximum journey
Arc light is reduced on degree to reveal in gap, ensures that the arc light that breaker sprays all is isolated.
4th, arc panel is projected as zhou duicheng tuxing on riser, and symmetry axis is overlapped with a diagonal of riser, draws
The outer edge of muscle aligns respectively with two edges of arc panel, and symmetrical structure allows the utility model there are two installation position
It puts, when installation need not be distinguished anyway, convenient for Fast Installation.
5th, using chlorosulfonated polyethylene as fire proofing, chlorosulfonated polyethylene not only has good flame retardant property, also
With good mechanical performance, good heat resistance, cold resistance and electrical insulating property, therefore it is applicable to high temperature or severe cold environment.

Fig. 2 is the sectional view at A in Fig. 1；
Fig. 3 is the stereogram of the utility model.
In figure：1- risers, 2- arc panels, 3- lacing wires, 4- plug divisions, 5- diagonal.
Specific embodiment
The utility model is described further below in conjunction with attached drawing：
The present embodiment include four pieces of risers, 1, three piece of arc panel 2 and three lacing wires 3, riser 1 be square structure, each riser
1 is equidistantly arranged in parallel, and is fixed between adjacent two pieces of risers 1 by one piece of arc panel 2 and a connection of lacing wire 3, arc panel 2
Riser 1 is each perpendicular to lacing wire 3.
Arc panel 2 is projected as zhou duicheng tuxing on riser 1, and symmetry axis is overlapped with a diagonal 5 of riser 1.
Arc panel 2 is projected as zhou duicheng tuxing on riser 1, and symmetry axis is overlapped with a diagonal of riser 1, outside lacing wire 3
Edge aligns respectively with two edges of arc panel 2, and symmetrical structure allows the utility model to pacify there are two installation site
It need not be distinguished anyway, convenient for Fast Installation during dress.
The lacing wire 3 is arranged on the inside of arc panel 2, and the edge of the riser 1 leaves to consolidate 1 grafting of riser
Fixed plug division 4 on-board the circuit breaker.It is close by the utility model and breaker size cooperation, can realize completely arc light every
From, arc light can be reduced to the full extent revealed in gap, the arc light that guarantee breaker sprays all isolation.
Riser 1, arc panel 2 and the lacing wire 3 is made of flame retardant rubber.The utility model, which uses, has fire retardation
Rubber insulation material, avoid by the high temperature scaling loss of arc light.In addition, rubber insulation material is cheap, difficulty of processing is small, due to
It is made of insulating materials, not having a power failure can install, i.e., do not influence to produce, installation and particularly convenient safety.
The outer edge of the lacing wire 3 aligns respectively with two edges of arc panel 2.
The flame retardant rubber is chlorosulfonated polyethylene.Using chlorosulfonated polyethylene as fire proofing, the poly- second of chlorosulfonation
Alkene not only has good flame retardant property, also with good mechanical performance, good heat resistance, cold resistance and electrical insulating property,
Therefore high temperature or severe cold environment are applicable to.
The utility model designed and produced one with the size shape of breaker it is matched, can be with the item that is carried on breaker
It is that shape slot grafting is connected, can by breaker three-phase arc light export isolate, can change arc light emission direction arc light isolation dress
It puts, it is simple in structure, easy for installation, arc light isolation effect is good, and can effectively avoid arc light and injure busbar.
