Description

Intensive insulation bus duct

Technical field

Field of power transmission is the utility model is related to, particularly a kind of intensive insulation bus duct.

Background technology

Busbar is provided with bus duct, to transmit electric energy, has the function of to collect and distribute electric power.By it, hair The electrical energy transportation that motor, transformer or rectifier export gives each user or other electric substations.

Bus duct instead of electric wire more and more in power Transmission trunk project project.Prosperity abroad Country, and the Hong Kong in China, Macao etc. have popularized.In the Guangzhou Guangdong in China, all more than 12 layers Building Power Distribution room outlets, that is, draw To 90% bus duct used above of backbone of floor；630KVA transformers to power distribution cabinet will use bus duct.Large- and-medium size cities Gongjian's project, hotel, using bus duct, also universalness, bus duct are the indoor following power Transmissions of rated voltage 1000V to office building The optimal selection of main line.

Since bus duct is in electric energy transmitting procedure, high current, high voltage are carry, therefore, bus duct product is to insulation Performance and internal heat dissipating all have high requirement, but existing bus duct is still hard to meet this requirement.

Utility model content

The main purpose of the utility model is that overcoming the deficiencies of the prior art and provide a kind of insulating properties and thermal diffusivity is all excellent Different intensive fireproof bus duct, the utility model are exhausted in the intensity by setting the through hole of heat dissipation in busbar conductor During edge bus duct long-time high current continuous firing, through hole can accelerate the circulation with surrounding air inside bus duct, by busbar Heat inside groove is taken out of, so as to effectively reduce the temperature inside bus duct, reduces bus duct because of temperature is excessive and triggers peace Total failure.

To achieve the above object, the utility model uses following technical scheme：

A kind of intensive insulation bus duct, including busbar protecting crust be arranged on some parallel mothers in busbar protecting crust Row, the busbar include busbar conductor and the insulating layer being coated on along busbar length direction in busbar conductor, it is characterised in that institute State and through hole is provided with busbar conductor.

Preferably, there are multiple through holes, in the case where not influencing electric property, at each in the busbar conductor Multiple through holes are respectively provided with busbar, can effectively reduce the weight of bus duct, while make radiating efficiency higher.

Preferably, heat-absorbing material is provided between the adjacent busbar, sets heat-absorbing material to make mother between adjacent busbar Arrange internal temperature more to stablize, heat conductive is more preferable.

Preferably, the gap filling in the busbar protecting crust and busbar protecting crust between some busbars being arranged in parallel has Heat-absorbing material and/or refractory material.

Preferably, some busbars being arranged in parallel integrally are placed in a built-in metal shell, the built-in metal shell and institute State between some busbars being arranged in parallel formed with the first filling slot, formed between the built-in metal shell and the busbar protecting crust There is the second filling slot.

Preferably, heat-absorbing material and/refractory material are provided with the filling slot.

Preferably, the heat-absorbing material is inorganic endothermic material, is magnesium hydroxide, aluminium hydroxide, hydrazine aluminum sulfate potassium, water Close one or more formation in calcium sulfate.

Preferably, the refractory material is resistance to guncotton and/or Ceramic silicon rubber.

Preferably, the insulating layer is Ceramic silicon rubber composite band and/or fire-resistant isinglass belt is entwined or heat-shrink tube The insulating layer formed through thermal contraction.

As described above, the utility model by setting the through hole of heat dissipation in busbar conductor, insulate female in the intensity During wire casing long-time high current continuous firing, through hole can accelerate the circulation with surrounding air inside bus duct, by bus duct The heat in portion is taken out of, so as to effectively reduce the temperature inside bus duct, reduces because of the safety failure that temperature is excessive and triggers.

Brief description of the drawings

Fig. 1 is a kind of structure diagram of intensive insulation bus duct of the utility model.

Embodiment

Elaborate below to the embodiment of the utility model.It is emphasized that the description below is only example Property, rather than in order to limit the scope of the utility model and its application.

Referring to Fig. 1, a kind of intensive insulation bus duct of the utility model, including busbar protecting crust 10 and it is arranged on busbar Some parallel busbars 20 in protecting crust 10, the busbar 20 include busbar conductor 21 and are coated on busbar along busbar length direction Insulating layer 22 on conductor, heat dissipation through hole 23 is provided with busbar conductor 21.

Busbar protecting crust 10 is the guard shield of intensive insulation bus duct, generally metal shell, such as steel or irony Housing, has the function that to protect bus duct internal part, and in the present embodiment, busbar protecting crust 10 is surrounded by four pieces of metallic plates, Two adjacent metal sheets are fixed together by bolt 12, can also be screwed.

Busbar 20 includes busbar conductor 21 and coats the insulating layer 22 of the busbar conductor 21.Have in busbar conductor 21 multiple Radiate through hole 23, and through hole 23 can accelerate the circulation with surrounding air inside bus duct, and the heat inside bus duct is taken out of, The purpose of the temperature inside bus duct is reduced so as to fulfill effect.Insulating layer 22 mainly plays insulating effect to busbar conductor 21, best Also there is fire resisting, preferably ceramic SiClx rubber composite belt at the same time, naturally it is also possible to be fire-resistant isinglass belt.Insulating layer 22 uses Ceramic silicon rubber composite band, can play the role of flame-retardant, flame-retardant excellent performance, burns even more than fire endurance Remain to ablation and form hard protective shell, protective shell can prevent flame from further extending to busbar conductor 21, so that guard bit It is without damage in the busbar conductor 21 in Ceramic silicon rubber composite band, it is ensured that the normal usage function of busbar 20, improves production The security of product.

In the present embodiment, some entirety of busbar 20 being arranged in parallel are placed in a built-in metal shell 30, the built-in metal Formed with the first filling slot 31, the built-in metal shell 30 and the mother between shell 30 and the busbar protecting crust 10 being arranged in parallel Formed with the second filling slot 32 between row 20, according to different place application demands, in the first filling slot 31 and/or the second filling The different functional material of filling in groove 32, such as heat-absorbing material and/or refractory material, meet high dissipate in intensive insulation bus duct Also there is heat conduction and/or fire resisting under conditions of hot.

In conclusion the utility model by setting the through hole of heat dissipation in busbar conductor, insulate female in the intensity During wire casing long-time high current continuous firing, through hole can accelerate the circulation with surrounding air inside bus duct, by bus duct The heat in portion is taken out of, so as to effectively reduce the temperature inside bus duct, and can meet high heat dissipation according to different application places Under conditions of property, moreover it is possible to easily make it have the function of heat conduction and/or fire resisting.

Above content is to combine specific/preferred embodiment further detailed description of the utility model, no It can assert that the specific implementation of the utility model is confined to these explanations.For the common skill of the utility model technical field For art personnel, without departing from the concept of the premise utility, it can also make the embodiment that these have been described Some replacements or modification, and these are substituted or variant should all be considered as belonging to the scope of protection of the utility model.
