Description
Technical field
The utility model relates to the online cable distribution device of using on a kind of city track traffic engineering contact system.
Background technology
The contact system type of existing city track traffic engineering is mainly divided into two kinds, rigid suspension catenary and flexible suspension contact system, rigid suspension catenary mainly adopts the array configuration of bus duct and contact wire, and flexible suspension contact system mainly adopts the array configuration of catenary and contact wire.The contact system of quovis modo, powers to contact system from traction substation at present, is substantially by online disconnector, adopts and is not more than 150mm
2direct current small bore cable form be directly connected with contact system, realize to the traction power supply of rolling stock.Because the type cross-section of cable is less, radical is many, for ease of with the bus duct of contact system or catenary is connected and operation safety is considered, does not all consider metal screen layer is set again, and one deck comparatively soft insulating barrier and oversheath etc. are only set.In actual engineering construction, because the traction current of locomotive is large, and the cross section of the type cable is less, causes its quantity more, and every loop generally need configure 8～12 150mm
2online cable, and due to field condition restriction, online disconnector with the online cable connection point of contact system apart from also relatively long.
Because city track traffic engineering underground space compactness is narrow and small, on-site cable laid condition is poor, in enforcement engineering, needs to be fixed on cable bearer, tunnel wall; Need be fixed at ground section on the facilities such as contact system column, such its oversheath of direct current small bore cable or insulating barrier are easily damaged; And because its surface is relatively soft, in long-term operation process, be easy to be damaged by rodents such as mouse, make to occur destruction of insulation between the facilities such as its energized conductor and cable bearer, tunnel wall or contact system column, cause current leakage; And in construction and operation process, be extremely difficult for finding, until develop into the situation of comparatively serious sparking, explosion or burning, the reliable operation of city track traffic engineering long-term safety that is positioned at Urban Underground to major part brings larger security against fire hidden danger, can not meet the requirement of the reliable operation of China's various places city track traffic engineering long-term safety.
For this contact system online cable connection mode,, constructability reliable from operation security installed and the angle of operation maintenance, proposes, in the online point of connection position of closing on contact system, cable distribution device is set, and realizes the optimization of contact system online cable connection scheme.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of contact system online cable distribution device, to realize the optimization of contact system online cable connection scheme, guarantee that operation security is reliable, and constructability is installed and operation maintenance.
It is as follows that the utility model solves the technical scheme that its technical matters adopts:
The utility model contact system online cable distribution device, it is characterized in that: this tapping device is made up of installation accessories, supporting insulator, cable connectors and cable tie bolt, installation accessories is detachably fixedly installed in the lower end of supporting insulator, cable connectors is detachably fixedly installed in the upper end of supporting insulator, on cable connectors along the spaced apart through hole being provided with for installing cables tie bolt of its length bearing of trend.
The beneficial effects of the utility model are as follows:
1, provide a kind of new cable distribution device to realize a kind of more convenient, safe and reliable contact system online cable or wire connection mode.Which can adapt to the convenient connection of the contact system online cable or wire of the various projects such as city track traffic engineering ground lower curtate, overhead and ground section.Can install fixing at tunnel top or sidewall, concrete pillar, steel column etc. in form.
2, adopt after this device, can by conventional scheme from online disconnector small bore online cable (the similar 150mm out
2or 120mm
2deng), be adjusted into the 400mm that protective is good, cross section is larger
2direct current cables, in the situation that online distance is constant, can reduce by the cable radical of a times; Simultaneously because charged and non-charging zone is crossed over more greatly and no longer in its cross section, can adopt the direct current cables with metal screen layer, can prevent in the cable installatition process under complex environment and the rodent such as mouse damages cable in long-term operation process insulating barrier; Even if damaging appears in its insulating barrier, also can in operation process, find early insulation fault and carry out in time fault handling, avoid the further expansion of accident.
3, this cable distribution device can be arranged on the place very approaching apart from contact system, is convenient to realize between contact system adopt 150mm in very short distance
2or 120mm
2direct current cables form, or directly adopt the uniform cross section naked copper flexible connecting line that current capacity is stronger directly to connect.
4, adopt after this device, can avoid similar 150mm
2or 120mm
2possibility that contact Deng small bore direct current online cable or naked copper flexible connecting line with the non-charging zone such as tunnel wall or pillar, after thoroughly solving such small bore online cable insulation and damaging appearance leak electricity, the phenomenon of detonation.
5, not adopting in the conventional scheme of this device, online cable is directly connected to contact system from online disconnector, this online cable jacket can be connected the charging zone of contact network cantilever insulator or suspension insulator both sides with non-live zone, under the external conditionss such as weather condition or tunnel leak such as certain ice, snow, rain, may there is occurring by cable jacket the hidden danger of electric leakage.Adopt after this device, can realize the isolation completely of Yu Fei live zone, contact net electrification region.
6, adopt after this device, the copper stranded conductor auxiliary feeder that elevated bridge section can be considered to cancel in contact system conventional scheme sets up, and connects as auxiliary feeder by the heavy in section direct current cables with screen layer, effectively improves the aesthetic property of net-contact engineering, improves on-the-spot view.
7, adopt after this device, that can actv. reduces small bore contact system online cable lays radical and length, improves the operation safety of engineering, and the aesthetic property of online cable installatition is improved in the space of simultaneously saving cable installatition.
8, adopt after this device, in operation process, if the online cable of drawing to the online disconnector of contact system power supply or from online disconnector breaks down, can easily at this cable distribution device place very near apart from contact system, this online disconnector or online cable thoroughly be separated with contact system efficiently, realize fast the charged normal operation of recovery of contact system.
In sum, for overcoming the deficiency of existing contact system online cable connection scheme, the utility model provides a kind of and has improved safe reliability, constructability is installed, is convenient to operation maintenance, saves the contact system online cable distribution device of tunnel installing space simultaneously.
