Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, to help, those skilled in the art conceive utility model of the present utility model, technical scheme has more complete, accurate and deep understanding.
Specific embodiment 1: the construction of cable of the present utility model comprises the cable core of many tape insulation layers, twining package tape and external sheath layer, and every root cable core is all provided with insulating barrier, and the cable core of many tape insulation layers is placed in wrapped belt, and external sheath layer is outside wrapped belt.Cable structure also comprises a Hollowed ventilation layer, and the heat produced during for taking away cable work, avoid temperature too high, cable will puncture, burn.
Hollowed ventilation layer is the ventilation duct of band lattice point structure, is provided with supporting bracket, avoids cable core to extrude, cause ventilation duct to be out of shape in pipe.As Fig. 1, ventilation duct is divided into several cavity by stay pipe, and the cable core interval of tape insulation layer is placed in cavity, and increase vent surfaces and amass, wherein, supporting bracket is also lattice point structure, improves ventilation effect further.This example structure is simple, and ventilation effect is good.
Cable is interval with through hole, and through hole, from Hollowed ventilation layer, through twining package tape and external sheath layer, is made the air in ventilation duct be exchanged by through hole and outside air, takes away heat.Due to weather effect, on rainy day, rainwater can enter cable inside by through hole, reacts with the aluminum material of cable inside, damages the construction of cable.Therefore, have for along the slide block of slide, a power line can being provided with powering to slide block in Hollowed ventilation layer of keeping off the rain at through hole peripheral hardware, in addition, slide block is connected to remote PLC control device, and PLC is provided with touch-screen, and staff is by the position of touch-screen Non-follow control slide block.
Outside through hole, be provided with water sensor, water sensor and slide block are fixed together, slide block inside can be located at, water sensor is shielded.Be provided with temperature sensor in through hole inside, for measuring the temperature of cable inside, water sensor and temperature sensor are powered through power line, and are connected to PLC.
Also be provided with blower fan outward at the through hole arranging water sensor, blower fan is used for the hot-air of cable inside to release, and realizes better cooling-down effect, and blower fan, water sensor and temperature sensor adopt same power line cooling, and are connected to PLC controller.When detecting rainy, namely starting slide block, blocking through hole, avoid rainwater to enter.
Specific embodiment 2: as Fig. 2, the ventilation duct in Hollowed ventilation layer and supporting plate structure are with embodiment 1, but the cable of tape insulation layer is placed in ventilation duct periphery, and this kind of structural rate embodiment 1 is processed simply.
Specific embodiment 3: as Fig. 3, Hollowed ventilation layer comprises ventilation duct, ventilation duct cross section is circular ring structure, comprise inner and outer tubes, between inner and outer tubes, be provided with supporting bracket, in the cavity that supporting bracket separates, the cable core of tape insulation layer is laid at interval, ventilation duct and supporting bracket are mesh-structured, and program cable core draught area is large, and ventilation effect is good.
Opening and closing and the operating power of blower fan are controlled by PLC, set pid algorithm to control the unlatching of blower fan, closed and operating efficiency in PLC.
First set a target temperature difference, the air themperature being passed the cable inside of coming by temperature sensor judges whether to open blower fan, and setting e is target temperature, sets e simultaneously
1as comparison other, the actual temperature e detected
xrepresent, wherein e<e
1, when the actual temperature detected is less than e, illustrate that the temperature of cable inside is not very high, setting power of fan is 0; Be greater than e when actual temperature and be less than e
1time, illustrate that load becomes large, need blower fan to add high power work, the operating power of setting blower fan is 50%, when the temperature detected is greater than e
1time, illustrate that temperature is higher, the setting fanman rate of doing work is 100%.Concrete, e
1be set to 1.5 times of e.
According to the actual temperature detected, the operating power under the setting open temp of blower fan and different temperatures, open blower fan waste electric energy when avoiding cable internal temperature not high, when also avoiding cable internal temperature too high, the operating power of blower fan can not meet cooling requirements.
