Abstract
The utility model provides a kind of photovoltaic plant DC electrical fireproof monitoring wire casing, and comprise wiring duct cover, wire casing body, thermometric line protect groove and thermometric line, thermometric line protects groove and is arranged on the inside cell wall of wire casing body, and thermometric line is arranged on thermometric line and protects in groove; The very first time just can find when direct current cables is overheated and navigate to one of them wire casing or terminal box, can improve and solve both at home and abroad for photovoltaic plant DC side early monitoring on fire, can not increase too much cost.
Description
Technical field
The utility model relates to photovoltaic DC generating electrical fire security field, particularly relates to a kind of photovoltaic plant DC electrical fireproof monitoring wire casing.
Background technology
Along with country is further to attention and the support of energy-conserving and environment-protective industry, domestic Ge Jia enterprise greatly develops wind-powered electricity generation, sun generating etc.; For solar energy, from 2008 so far, domestic with multi-form promotion green solar power engineering such as golden sun engineering, ARCHITECTURE OF DISTRIBUTED ENGINEERING DBMS, surface power station, power stations, roof, with regard to 2014, according to Chinese Credit actuarial, install about 44GW in the whole world, wherein China installs about 10.5GW, and estimate that global power plant construction gross investment is about 4,400 hundred million yuan, China is about 1,050 hundred million yuan, within 2015, estimate global 55GW, China guards as 15GW.
At present, be electrically connected with 1kv-1*4mm direct current cables because photovoltaic plant electric power collects with conveying 70%, each generator unit will be using electrical connector as cut-in point position; Because direct current cables distribution is comparatively expanded, electrical connector is too much, the reasons such as electric short circuit, construction reason and environmental aging, very easily cause electrical fire, and this direct current component transmission voltage grade is generally 600V to 1000V, unavailable general water carrys out calamity fire, such causing more large-arealy crosses electricity and jeopardizes fire extinguishing life safety, again because photovoltaic plant area is excessive, general conventional 3MW power station about takes up an area 100 mu, with other fire-fighting mode too less than efficiency, because electrification in high voltage can not adopt above-water method, sometimes can only soon power station burning and without countermeasure; Therefore the Timeliness coverage at the beginning of power station fire is shaping just seems and for important, and cable testing bridge wire casing and terminal box etc. do not possess this kind and monitor the function of fire point Timeliness coverage before high-temperature level in advance at present, solve in the urgent need to us.
Utility model content
The purpose of this utility model is to provide a kind of photovoltaic plant DC electrical fireproof monitoring wire casing, and the solution very first time just can find when direct current cables is overheated and navigate to wire casing or the terminal box of one of them position.
To achieve these goals, the technical solution of the utility model is to provide a kind of photovoltaic plant DC electrical fireproof monitoring wire casing, comprise wiring duct cover and wire casing body, also comprise thermometric line and protect groove and thermometric line, thermometric line protects groove and is arranged on the inside cell wall of wire casing body, and thermometric line is arranged on thermometric line and protects in groove.
Thermometric line protects protecting on cell wall of groove and is provided with through hole or aperture slots.
The cell wall that protects that aperture slots protects groove along thermometric line is longitudinally arranged.
Thermometric line protects groove and is provided with more than one or two.
The inside cell wall that thermometric line protects groove and wire casing body is wholely set.
The beneficial effects of the utility model just can find when direct current cables is overheated and navigate to one of them wire casing or terminal box in the very first time; Can improve and solve both at home and abroad for photovoltaic plant DC side early monitoring on fire; Too much cost can not be increased.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
Wherein: 1-wiring duct cover, 2-wire casing body, 3-cable, 4-thermometric line protects groove, 5-thermometric line.
Embodiment
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing, protection content is not limited to the content of embodiment.
Embodiment as depicted in figs. 1 and 2, the present embodiment provides a kind of photovoltaic plant DC electrical fireproof monitoring wire casing, or also can be terminal box, comprise the parallel thermometric line of wiring duct cover 1, wire casing body 2, two and protect the thermometric line 5 that groove 4 and every bar thermometric line protect groove inside, the longitudinal direction of protecting groove 4 along thermometric line is protected on cell wall and is provided with aperture slots, or also can be provided with through hole, thermometric line protects groove 4 and is arranged on the inside cell wall of wire casing body 2, and the inside cell wall making thermometric line protect groove 4 and wire casing body 2 is wholely set, thermometric line 5 is arranged on thermometric line and protects in groove 4.
The temperature of thermometric line to cable 3 that the present embodiment adds a kind of energy testing temperature in conventional aluminum alloys wire casing production technology is monitored, there is temperature reception device one end in addition, temperature reception device can identify temperature in thermometric region, the temperature variations of this generator unit can be reflected to upper level within the scope of design temperature, when the alarm that goes beyond the scope, by fire control below initiation temperature.
The beneficial effect of the present embodiment just can find when direct current cables 3 is overheated and navigate to one of them wire casing or terminal box in the very first time; Can improve and solve both at home and abroad for photovoltaic plant DC side early monitoring on fire; Too much cost can not be increased.
