Abstract
The utility model relates to switch equipment spare and accessory parts in an electric power system, particularly to a heat dissipation rack mounted on an embedded pole. The heat dissipation rack comprises an integrally-molded pedestal. An arched door is formed on one side surface of the pedestal. The other three side surfaces of the pedestal are all provided with inward vertical cooling fins. The middle place of the upper surface of the pedestal is provided with a groove. The back surface of the pedestal is provided with a connecting seat connected with the embedded pole. A bolt hole is formed in the connecting seat. The heat dissipation rack has good thermal conductivity and is capable of cooling cathode spots, enabling the metallic vapor concentration to be low, and ensuring the normal making and breaking of a vacuum arc-extinguishing chamber. The heat dissipation rack is simple in structure and reasonable in design, and is beautiful and firm.
Description
Technical field
The utility model relates to the switchgear spare and accessory parts in electric power system, especially a kind of heat radiation rack being arranged 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 ensureing 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 ensures that vacuum interrupter normally cut-offs.Existing heat abstractor is directly connected on pole by bolt, and bolt is connected to the outside of heat abstractor, neither attractive in appearance, also insecure.
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 heat radiation rack being arranged on pole.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat radiation rack being arranged on pole, comprise integrated base, on one side of described base, offer an arched door, on its excess-three side of base, be equipped with inside vertical radiating fin, the medium position of the upper surface of described base is provided with groove, the back side of described base is provided with the Connection Block being connected with pole, on described Connection Block, is opening bolt hole.
Further, on the upper surface of described base, be also provided with inside radiating fin.On solid-state pole, there is metallic vapour, in order to prevent that metallic vapour from directly entering air and just need to lower the temperature to metallic vapour, so be also provided with inside radiating fin on the upper surface of base.
Further, two base sides that are provided with inside vertical radiating fin are arcuate structure.The base side of design arcuate structure is the volume in order to increase base, is also for heat radiation better.
The beneficial effects of the utility model are: the utility model has good heat conductivity, can allow cathode protection cooling, make metallic vapour concentration low, ensure that vacuum interrupter normally cut-offs, and the utility model is simple in structure, reasonable in design, both attractive in appearance, also firmly.

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, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figures 1 to 3, a kind of heat radiation rack being arranged on pole, comprise integrated base 1, on one side of base 1, offer an arched door 2, on its excess-three side of base 1, be equipped with inside vertical radiating fin 3, the medium position of the upper surface of base 1 is provided with groove 4, and the back side of base 1 is provided with the Connection Block 5 being connected with pole, is opening bolt hole 6 on Connection Block 5.The connection of base 1 and pole can be conveniently observed in the design of arched door 2.
Further, on the upper surface of base 1, be also provided with inside radiating fin 3.On solid-state pole, there is metallic vapour, in order to prevent that metallic vapour from directly entering air and just need to lower the temperature to metallic vapour, so be also provided with inside radiating fin 3 on the upper surface of base 1.
Further, two base 1 sides that are provided with inside vertical radiating fin 3 are arcuate structure.Base 1 side of design arcuate structure is the volume in order to increase base 1, is also for heat radiation better.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment 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.
