Description
Technical field
The utility model relates to the switchgear spare and accessory parts in electric power system, especially a kind of for the heat radiation rack on pole.
Background technology
Vacuum interrupter is also vacuum switch tube or vacuum bubbles, is the core devices of vacuum circuit-breaker (switch), is loaded in pole.It is with a pair of sealing electrode (contact) and other part in a vacuum, by the good insulation of vacuum and blow-out performance, realizes closing or disjunction of circuit, rapidly blow-out restrain the vacuum device of electric current after cutting off the electricity supply.
Vacuum interrupter is in the process of drop-out current, and in vacuum switch, the melting welding of contact is distinct issues.Melting welding between vacuum contact is almost inevitably, thereby can only require the melting welding power between contact not too large, and after contact generation melting welding, melting welding point can be fallen by broken ring easily under the effect of separating brake power.In order to reach this object, usually utilize the segregation phenomena of alloy material, make the melting welding point between contact become very fragile.In order to meet the requirement of large rated current, contact material must have very high conductance, high conductive coefficient and little contact resistance, so that the power loss of contact portion is less and as soon as possible the dissipation of heat of generation is gone out, high mechanical strength is that the mechanical shock while guaranteeing that contact bears divide-shut brake is necessary.So the area in contact surface arc spot melting zone is little, depth as shallow, thermal inertia is little, its, constant only had several microseconds cooling time, in vacuum interrupter normal operating conditions, contact is closed, and electric current by contact and circuit breaker is often up to 2000A, the rising of passing through to cause each contact temperature in vacuum interrupter of large electric current, has had a strong impact on useful life of vacuum interrupter and circuit breaker.Therefore utilizing and have the heat abstractor of good heat conductivity cooling by cathode protection, make metallic vapour concentration low, is an essential condition that guarantees that vacuum interrupter normally cut-offs.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of for the heat radiation rack on pole.
The utility model solves the technical scheme that its technical problem adopts: a kind of for the heat radiation rack on pole, comprise heat radiation rack body, described heat radiation rack body comprises the base plate of portal structures and is positioned at the fin on base plate, described fin comprises the fin of strip structure and the fin of wavy shaped configuration, the back side of described base plate is provided with the Connection Block being connected with pole, on Connection Block, offer screwed hole, on four angles of described base plate, be also provided with seal.
Further, described fin has five, and wherein a slice is the fin of wavy shaped configuration.The fin of prior art is all the fin of strip structure, in design fin, having a slice is the fin of wavy shaped configuration, because there is metallic vapour on solid-state pole, in order to prevent that metallic vapour from directly entering air and just need to reduce metallic vapour concentration, the fin of design wave shape structure can increase the shock of metallic vapour, reaches the effect that reduces metallic vapour concentration.
Further, the height of described Connection Block and the height of base plate are consistent.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, have good heat conductivity, can allow cathode protection cooling, make metallic vapour concentration low, guarantee that vacuum interrupter normally cut-offs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
In figure: 1. base plate, 2. fin, 3. Connection Block, 4. screwed hole, 5. seal, the fin of 21. strip structures, the fin of 22. wavy shaped configuration.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figures 1 to 3, a kind of for the heat radiation rack on pole, comprise heat radiation rack body, heat radiation rack body comprises the base plate 1 of portal structures and is positioned at the fin 2 on base plate 1, fin 2 comprises the fin 21 of strip structure and the fin 22 of wavy shaped configuration, the back side of base plate 1 is provided with the Connection Block 3 being connected with pole, offers screwed hole 4 on Connection Block 3, on four angles of base plate 1, is also provided with seal 5.
Further, fin 2 has five, and wherein a slice is the fin 22 of wavy shaped configuration.The fin 2 of prior art is all the fin 21 of strip structure, in design fin 2, having a slice is the fin 22 of wavy shaped configuration, because there is metallic vapour on solid-state pole, in order to prevent that metallic vapour from directly entering air and just need to lower the temperature to metallic vapour, the fin 22 of design wave shape structure can increase the shock of metallic vapour, reaches the effect of cooling.
Further, the height of Connection Block 3 is consistent with the height of base plate 1.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
