Description

A kind of Novel bus duct

Technical field

The utility model belongs to transmission & distribution electro-technical field, and in particular to a kind of Novel bus duct.

Background technology

Bus duct is a kind of transmission and distribution line circuit component of relatively high power in distribution system.Compared with traditional electric wire, Have many advantages, such as that small, capacity is big, the design and construction period is short, be convenient to mount and dismount, securely and reliably, service life it is long.Bus duct skill Art has tended to be perfect substantially, and not only insulating radiation performance, flame retardant property are good, and overload capacity is strong；And assembly and disassembly, tap are conveniently.

When the conducting copper of bus duct system circuit occurs abnormal, amount of heat is generated inside bus duct, leads to busbar Tank systems line temperature constantly increases, or even causes spark or fire, to damage bus duct system.In the prior art, one As using fire prevention liner or extinguishing device come the spark or fire condition of control bus slot built-in system.Fire prevention liner is generally whole The structure of chip, when localized hyperthermia causes spark or fire in bus duct system, though fire-retardant effect can be timely played, Maintenance needs full wafer to scrap later, is unfavorable for the saving of resource.And extinguishing device generally uses dry powder extinguisher or carbon dioxide to go out Firearm, fire extinguisher can not automatic sensing temperature variation, also need to add temperature sense control device, cause bus duct weight load After exacerbation, improves the cost of production, and dry powder extinguisher puts out fire behavior, dry powder powder or the surface for being sticked to busbar, no Recycling easy to clean, causes busbar to scrap.

Specific implementation mode

The utility model is described in detail with reference to the accompanying drawings and examples.

Novel bus duct in the embodiments of the present invention as shown in attached drawing 1,2, including shell and be located at shell intracavitary Busbar 1；

Shell is made of two cover boards and two side plates, and cover board 2 and side plate 3 are the flat U-type groove structure of opening outwardly； Two cover boards are symmetrical above and below, and two side plates are symmetrical；Two side plates are bolted between two cover boards, form shell Chamber；

It is equipped with the fire retardant package 4 piled up successively at the both ends gap of shell intracavitary, busbar periphery and shell chamber.Fire retardant package Thickness be 10-30mm；Fire retardant package is equipped with 3-5 layers in shell intracavitary, busbar periphery；1- is equipped at the both ends gap of shell chamber 2 layers.

Busbar is multiphase copper bar, and outer layer is enclosed with insulating layer, and insulating layer is the raw material band for being wound in busbar surface. The interface for protruding from busbar can be set on busbar, and be connected with jack box by interface.Interface and jack box phase Fire retardant package is even also equipped at gap, the number of plies is 1-2 layers.

The U-type groove bottom of side plate is equipped with the strip fin that section is tooth form.Envelope is provided at both ends in the U-type groove of two cover boards First 5, end socket is bolted on cover board.The L-type sealing plate 6, L inwardly there are two opening is all provided on the outside of shell both ends, busbar Type sealing plate is bolted on end socket.

In the embodiments of the present invention, shell intracavitary, busbar periphery in bus duct, at the both ends gap of shell chamber with And branching port is connected at gap with jack box and is equipped with fire retardant package, and busbar pot shell intracavitary portion is made to form a closed space, it can The harmful substances such as effective moisture, the dust avoided in external environment enter busbar pot shell intracavitary portion, to busbar pot shell intracavitary Busbar impacts, and causes bus duct job insecurity.Fire retardant package outer layer is used by weaving closely, specially treated durable Glass fabric is made bag-shaped, and inside filling special type fire, heat-barrier material and expanding material have noninflammability, fire endurance can Up to 4 hours or more, a kind of heat-insulated, every cigarette sealing structure, and the fire prevention good anti-moisture ability of fire retardant package are formed, it is toxic without asbestos etc. Object composition.When the busbar continue working in busbar pot shell intracavitary portion, temperature constantly increases, when causing spark or fire, fire retardant package Expansion and solidification rapidly at high temperature, forms fire-retardant protective layer, prevents spark from spreading, and causes fire disaster, effective to improve The security performance of bus duct entirety.Simultaneously when fire occurs for the external world, the safety of bus duct system is protected, keeps bus duct normal Operation.

Block pattern row pattern is at fire-retardant protective layer successively for the fire retardant package that multiple thickness are 10-30mm, outside shell intracavitary, busbar It encloses and is equipped with 3-5 layers；1-2 layers are equipped at the both ends gap of shell chamber；It is connected with jack box at gap in branching port and is equipped with 1-2 Layer.A kind of multi-tiling is formed on the bus duct that need to be blocked, the protection structure of layering causes spark when bus duct localized hyperthermia Or when fire, the position for contacting high temperature expands rapidly and solidification forms flame-retardant layer, prevents spark from spreading.And not in contact with high-temperature part Fire retardant package, bus duct maintenance after can also continue to recycle, effectively saved resource.

The utility model is can be seen that from the scheme of above-described embodiment and provides a kind of Novel bus duct, and the bus duct is not Only there is good moisture-proof, sealing performance, and with good fire resisting, flame retardant property.

Finally, it should be noted that above example is only to illustrate the technical solution of the utility model embodiment rather than right It is limited, although the utility model embodiment is described in detail with reference to preferred embodiment, this field it is common Technical staff should understand that still be modified or replaced equivalently the technical solution of the utility model embodiment, and this A little ranges changed or equivalent replacement cannot also make modified technical solution be detached from the utility model embodiment technical solution.
