Abstract
The utility model discloses an inlet and outlet wire bus frame of a breaker frame. Two bus strut members are matched with each other; the bus strut members are respectively provided with through holes at the corresponding positions; a bolt fixes the inlet and outlet wire bus frame of the breaker frame by passing through the through holes; the bolt comprises a bolt head, a bolt bar, and a reinforcing part between the bolt head and the bolt bar, wherein the cross section area of the reinforcing part is polygonal and larger than that of the bolt bar. The inlet and outlet wire bus frame of the breaker frame adopts the bolt with certain intensity to fix the bus, thus tight and firm engagement is realized, and bus looseness is avoided even if large current flows through the bus.
Description
Technical field
The utility model relates to low-voltage distribution equipment, is specifically related to a kind of circuit breaker frame line bus-bar frame.
Background technology
Divide in the power distribution equipment at transformer, some electric substation does not use breaker apparatus, only uses isolating switch as bar coupler, owing to only isolating switch being arranged circuit breaker is not set, when these transformers are in gate-dividing state, can't electrically chargedly carry out sub-switching operation.And a minute power distribution equipment is kept away unavoidably meeting with positive and negative charge when carrying out breaking-closing operating in actual life.So most electric substation can adopt circuit breaker to cooperate the use of bus contact cabinet.When carrying out sub-switching operation, the electric current of not only will flowing through on the circuit breaker bus also will bear the huge electric impacting power that produces when breaker apparatus is in short circuit.Loosening for the bus of avoiding causing because electric current is excessive in the circuit breaker course of work, people have invented the circuit breaker bus-bar supporting piece and have been used for circuit breaker bus row is fixed and supports.
A kind of insulation component for bus is disclosed such as existing patent documentation CN101485058A, this insulation component comprises the main body of being made by insulating material along this axis transverse between two end faces of longitudinal axis, described main body comprises a plurality of sides, has at least two sides to be provided with groove and the groove longitudinal extension length of ipsilateral is different.These insulation component insulation property are good, can support the bus of different size, and versatility is good, can be as circuit breaker bus strutting piece.Need to adopt a plurality of bolt fixed insulation elements and location cross member etc. in the such scheme, the bolt head of existing plain bolt generally all is the shapes such as turret head, square spigot, countersunk head, these bolts are used very extensive, use also very convenient, but in use, have the excessive situation of electric current on the bus, for the loosening bolt that needs that prevents bus possesses certain strength, existing general bolt can't reach this effect.In addition, this insulation component in the technique scheme can't be realized separately the fixing of bus and support, need external auxiliary location cross member to realize, so so that the complex structure of insulating part, be not easy to production and processing, and the making of the additional processing of align member, also increased production cost, wasted resource.
The utility model content
The utility model is inadequate for the bolt strength that is used for fixing bus-bar frame in the circuit breaker bus-bar supporting piece in the prior art, long-term use easily causes the loosening technological deficiency of bus, and then proposes a kind of fixing circuit breaker frame line bus-bar frame of certain strength bolt that adopts.
A kind of circuit breaker frame line bus-bar frame is cooperatively interacted by two bus-bar supporting pieces, and position corresponding on each described bus-bar supporting piece is provided with through hole, and bolt passes the fixing described circuit breaker frame line bus-bar frame of described through hole.
Described bolt comprises bolt head and shank of bolt, and is arranged on the rib between described bolt head and the described shank of bolt, and the cross-sectional area of described rib is greater than the cross-sectional area of described shank of bolt; And the shape of cross section of described rib is polygon.
The height of described rib is greater than or equal to the radius of described shank of bolt, and less than the length of described shank of bolt.
The some slots that mate with bus are set on described bus-bar supporting piece the first side, are provided with the described through hole that is suitable for described bolt insertion between adjacent two described slots; Its second side and described the first side over against, on described the second side with described at least one louvre of each moulding of slot relative position.
The width of described slot is 82mm, and the degree of depth is 4.5mm.
The above slot number of described the first side is three, and the number of described through hole is four.
The cross section of described through hole is hexagon.
Be spaced apart 4mm between described slot and the described through hole.
On described the second side with two louvres of each moulding of described slot relative position.
The cross section of described louvre is rectangle.
The overall dimension of described bus-bar supporting piece is: long 420mm, wide 25mm, high 34.5mm.
Technique scheme of the present utility model has following advantage:
(1) a kind of circuit breaker frame line bus-bar frame of providing of the utility model, the bolt of employing certain strength is bus fixedly, between the nuts of bolt and the described shank of bolt rib is set, and the shape of cross section of rib is polygon, effectively raises the rigidity of bonding strength and bolt part.And,, conveniently tighting a bolt to needing the fixing of securing member by reinforcing section, the interlock consolidation is firm, even also can not cause the loosening of bus when having larger electric current to flow through bus.
(2) a kind of circuit breaker frame line bus-bar frame of providing of the utility model only relies on being used in conjunction with in twos of bus-bar supporting piece, even without the support of external location cross member, bus is linked in the power distribution equipment securely.
