Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
During conventional high-tension cable is produced, a lot of limitation is existed to the detection of decontamination chamber's environment key element.Therefore, first applicant has carried out detailed investigation and analysis to the impact that VCV production line manufactures various environmental element in high-tension cable process, then just have developed native system.Investigation and analysis is as follows:
(1) impact of temperature.For high-voltage cable insulating and shielding material, too high storage temperature may cause material breakdown to be lumpd.Decontamination chamber is the unfavorable heat radiation of enclosed construction, and the head of heating and extruding machine are huge thermals source, if do not have air-conditioning temperature-reducing, the temperature in operation room can soar to more than 40 DEG C.Too high temperature also can affect the heat radiation of Survey control module electronic components and parts, shortens its serviceable life, and because the overheated misoperation causing control device, brings huge potential risk to continuous seepage.From the angle that employee shows loving care for, high temperature can aggravate working strength, reduces enthusiasm and the efficiency of work.Therefore, the temperature of general provision feed compartment is not higher than 30 DEG C, and the temperature of operation room is not higher than 35 DEG C.
(2) impact of humidity.Pure tygon is hydrophobic material, and therefore insulating material generally can not make moist, but owing to adding a large amount of graphite to conduct electricity in inside and outside screen material, inside and outside screen material very easily makes moist.Damp and hot acting in conjunction can accelerate the corrosion of metal material, reduces the serviceable life of production equipment and control system.For being located in southern cables manufacturing enterprise, the impact of humidity is more obvious, the plum rains time in summer, and relative humidity even can more than 90% close to saturated.In order to eliminate the impact of humid air, needing air-conditioning to lower the temperature dehumidifying simultaneously, generally the relative humidity of decontamination chamber being controlled be no more than 60%.
(3) impact of air purity.Dust impurity is very large on the impact of the dielectric strength of high-tension cable, for 110kV high-tension cable, correlation standard: " should without the opaque impurity being greater than 0.125mm in finished cable insulation, be greater than 0.05mm and the opaque impurity being less than 0.125mm at 16.4cm
3no more than 10 are answered in insulation." according to unit volume dust in air numbers of particles; decontamination chamber can be divided into the ranks such as hundred grades, thousand grades, ten thousand grades, 100,000 grades; insulated charging room is hundred grades (500kV electric pressure cables), thousand grades (220kV and following electric pressure cable); interior external shield feed compartment is ten thousand grades, and operation room is 100,000 grades.
(4) impact of cross-linking by-products.Crosslink agent DCP is in cross-linking tube decomposes, produce the accessory substances such as methane, acetophenone, cumyl alcohol, methyl styrene and moisture, except methane and moisture, other material is translucent sticky shape solid, with hot-air volatilization and in the condensation of low temperature place, these accessory substances have strong and stimulating smell and strong oxidizing property, and meeting corroding metal and harm enterprise employee health, need to carry out condensation recovery by retracting device.Though methane is nontoxic, belong to flammable explosive gas, its in atmosphere content just may be detonated more than 5%.Operation room arranged alongside has crosslinked pipeline nitrogen distribution plant, containing a large amount of methane in the waste gas of being discharged by nitrogen distribution plant, easily enrichment in operation room decontamination chamber, owing to there being a large amount of thermal source in operation room, in order to prevent Lighting-blast casualty from occurring, need to detect the concentration of methane gas in operation room decontamination chamber.
(5) threat of fire.Current most of decontamination chamber is built by color steel/styrenic foams composite plate, has light, the easy processing of weight, low cost and other advantages, but also there is the not fire-retardant fatal defects of easy firing, the common all reports of the fire failure caused thus.From the angle of safety in production, carrying out early detection early warning to the contingent fire in decontamination chamber is also the important content of environment measuring.
Based on aforementioned investigation, create the utility model system, native system is arranged in decontamination chamber, and decontamination chamber is made up of insulated charging room, inside and outside screen feed compartment and operation room.The structure of native system as shown in Figure 1, forms primarily of Temperature Humidity Sensor 5, laser dust particle counter 3, infrared methane detection alarm instrument 2, Point-type fire detectors 4, multi-channel data acquisition board and PC end.Temperature Humidity Sensor 5, laser dust particle counter 3, infrared methane detection alarm instrument 2, Point-type fire detectors 4 are all connected to multi-channel data acquisition board, and multi-channel data acquisition board is connected to PC end.In order to realize instant alarming, native system is also provided with alarm 1, and this alarm is held with PC and is connected.According to signal properties, channel quantity and sample frequency, choose 16 channel data capture cards, by usb bus, data are passed to PC end.The concrete installation of each sensor is as follows:
In decontamination chamber, arrange Temperature Humidity Sensor 5, realize detecting while temperature and humidity, wherein: insulated charging room installs 1, inside and outside screen feed compartment installs 1, and operation room evenly installs 4 along wall.Temperature Humidity Sensor being arranged on vertical height (according to floor or workbench) is on decontamination chamber's inwall of 1.5 meters, the working depth of this temperature and major equipment is close to being convenient to safeguard, the temperature of insulated charging room is not higher than 30 DEG C, the temperature of operation room is not higher than 35 DEG C, and the sampling period is 1 minute/each.
