Abstract
The invention relates to spare parts of switching equipment in a power system, and in particular relates to a radiating frame mounted on a solid-sealed polar pole. The radiating frame comprises an integrally formed base; an arch door is formed one side surface of the base; inwards vertical radiating fins are arranged on the rest three side surfaces of the base; a groove is formed in the middle part of the upper surface of the base; a connecting seat connected with the solid-sealed polar pole is arranged on the rear surface of the base; a bolt hole is formed in the connecting seat. The radiating frame is high in heat transfer performance; cathode spots can be cooled; metal steam concentration can be reduced; a vacuum arc-extinguishing chamber can be disconnected normally; the radiating frame is simple in structure, reasonable in design, nice, and firm.
Description
Technical field
The present invention relates to the switchgear spare and accessory parts in electric power system, especially a kind of heat radiation rack be 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 sealing electrode in a vacuum (contact) and other part, the insulation excellent by vacuum and blow-out performance, closing or disjunction of realizing circuit, can 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 inevitable, and thus can only require that the melting welding power between contact is not too large, 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 utilizing the segregation phenomena of alloy material, making the point of the melting welding 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, to make the power loss of contact portion less and distributed by the heat of generation as soon as possible, high mechanical strength is that mechanical shock when 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 microsecond cooling time, in vacuum interrupter normal operating conditions, contact is closed, and by the electric current of contact and circuit breaker often up to 2000A, the rising by causing each contact temperature in vacuum interrupter of big current, has had a strong impact on the useful life of vacuum interrupter and circuit breaker.Therefore utilizing has the heat abstractor of good heat conductivity to cool by cathode protection, makes metallic vapour concentration low, is the essential condition ensureing 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, both unsightly, also insecure.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of heat radiation rack be arranged on pole.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of heat radiation rack be arranged on pole, comprise integrated base, one side of described base offers an arched door, its excess-three side of base is 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 be connected with pole, and described Connection Block has open bolt hole.
Further, the upper surface of described base is also provided with inside radiating fin.Solid-state pole has metallic vapour, and directly entering air to prevent metallic vapour just needs metallic vapour cooling, so the upper surface of base is also provided with inside radiating fin.
Further, two base side being 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 to dispel the heat better.
The invention has the beneficial effects as follows: the present invention has good heat conductivity, cathode protection can be allowed to cool, make metallic vapour concentration low, ensure that vacuum interrupter normally cut-offs, structure of the present invention is simple, reasonable in design, both attractive in appearance, also firmly.

Embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
As shown in Figures 1 to 3, a kind of heat radiation rack be arranged on pole, comprise integrated base 1, one side of base 1 offers an arched door 2, its excess-three side of base 1 is 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 be connected with pole, Connection Block 5 has open bolt hole 6.The design of arched door 2 conveniently can observe the connection of base 1 and pole.
Further, the upper surface of base 1 is also provided with inside radiating fin 3.Solid-state pole has metallic vapour, and directly entering air to prevent metallic vapour just needs metallic vapour cooling, so the upper surface of base 1 is also provided with inside radiating fin 3.
Further, two base 1 sides being 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 to dispel the heat better.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
