Bimetallic thermometer share little secret power station common faults

My group, group series of safety fuse is scores ranking No. 1. , of course, the role of insurance is the important device by fusing function to maintain the peace, is also on the list with achievement first, secondary is due to the large proportion of fusing, and is not due to the group of series of problems triggered the insurance mechanism, but the insurance 'commit suicide'. Fuse together, attack scene from group series power outage probability actually is not high, about one over one thousand of that within a week or so. But to hold equipment, like I'm in xingtai station, about 3000 groups, there are 1 - every week about Fusing conditions of attack 2 times, and the probability of 99% belong to fuse insurance itself. Can think about some of the larger capacity, relative number will be added. For disposal of safety fuse, absolutely is not complicated. Present fusing scene group list data associated degree of abnormal reaction in our automatically Sana 'a control platform, when the staff received degree, abnormal alarm in adhere to standards under the condition of safe and only needs to the scene to identify measure degree of insurance of insurance of the positive and negative current, can accurate positioning problem, change new insurance. Practice tasks, and about 70% of the problem will appear on the insurance of the cathode. Can a lot of line operation personnel, once the change of insurance as a local daily tasks, and to consider from the Angle of view of the problem again. Indeed, from other equipment, absolutely insurance own existence of attribute, the slow loss of resolution change shall not prevent the aging. But from the Angle of fault analysis, we can do to increase loss, perhaps early forecasting results attack, further reduce risk. According to the view we can find that the insurance device about the rapid lifting inside short time current is very sensitive, to the rapid changes and current, and attracted by irradiation conditions change. So we can be completely according to own power station area of irradiation change trend, to positive anticipation with high incidence of throttle, perhaps time and adjust the number of spare parts demand, make a change in maintenance tasks more rapid and more worry. Bimetallic thermometer dc grounding short-circuit bimetallic thermometer, adsense online talk columns also talked of repeated, because this is a line for power plant personnel's nightmare. And insurance, fusing the result compare grounding fault frequency is much lower, sometimes will be sporadic several times a year. But the present grounding fault, quite area will suspend power generation equipment, impact on electricity is very clear. At the same time, because of various power plant design and the terrain is different, in addition to the factory, the factory outside the bimetallic thermometer will I have the status of the ground attack, let a person feel small-scale operations. Unlike safety fuse, bimetallic thermometer ground disposal up to some. We passed the control platform, is offline, can rapidly find area locating grounding contact is more time-consuming. Like xingtai stand that kind of mountain hydropower station, the uneven, cable layout is complicated, only after the appearance of the complex reflection has to be able to find problem. Can according to the area of the cable environment condition at this moment, for example with gravel, the weight of cables such as ping an has coerce beginning self-reflection, ordinary can find scores points faster. At the same time, demand note is not eliminate multiple grade point of showing in the same area, so the advice is stop to reflect to risk status, specially do the clearing and maintenance. As fighting in the operating personnel, said a suspected 'pot' word, bimetallic thermometer grounding fault amount, and power station set up perfect or not, has a very big correlation. Some power stations in establishment stage, including monomer, group of lines, dc bimetallic thermometer, cables, made such as adding cable box, prevent the protection, such as pressure steel structure to early to avoid the effect of the grounding fault is very distinct. There are some due to rob to 630, to the specification requirements of some protection is ignored, but led to grounding grid generation after frequent performance, staff are busy digging holes plane line, continue to influence power generation benefits. Want to increase the ground impact, our operational control personnel can pay more attention to the following: no matter when took over power station management, for the first time for total station cable for a comb reflection, combined with the power plant environmental conditions do a evaluation, there is a serious risk forecast report, add conditions permit stop protection. To have a large number of protection, but protective equipment aging may lack of enough, stop signs, periodic point to reflect and consolidate, don't wait to achievement attacks that moment to beginning treatment. SVG equipment problems of various kinds of equipment such as tank often have gathered a lot of equipment, SVG, data bits and pieces and monitor spare device such as a important components are integrated together. The sun of absolute area, has a shell maintenance equipment less present achievements, it is also because once the terminal equipment, total power generation will be affected, demand of all the maintenance. Match would face, is an unknown disease, such as SVG can't operate this situation. This brought a lot of trouble to your daily tasks, like bits of downtime, seems to be too much randomness, want to prevent feel do not know how to start. About SVG devices such as unknown problem, first of all, remember: don't panic! About entering the industry colleague, the sight of the normal power walks rendering results, are filled with tears, is due to the tense and the controls. So, don't panic, calm up for performance is the first step. Then, about the total spare monitor to plant, as soon as possible with the aid of bits and pieces, while positioning to what is wrong with the equipment. The demand for power station control bits and pieces of strong data management and analysis ability. If be the circuit performance, etc, timely report to the owner and the equipment manufacturer to repair as soon as possible. Plant personnel adjustment at the same time according to the status of the equipment fault emergency task arrangement, it is important to other tasks to ensure the normal and orderly.
