Abstract
The invention discloses a forest fire trip test platform for a transmission line. The forest fire trip test platform consists of a voltage regulator (1), a transformer (2), a resistor (3), an electrode (4) and a grounding electrode (5) which are connected in series in sequence, wherein the electrode (4) is connected with the grounding electrode (5) in a line with an adjustable air gap-line electrode form or a rod-rod electrode form or a rod-plate electrode form; and when the voltage exceeds the tolerance level of the air gap between the electrode (4) and the grounding electrode (5), the air gap is broken down. Air gap breakdown voltage values under different conditions can be obtained through the air gap distance and the fire behavior; and the trip factors and rules of the transmission line are analyzed. The platform has the following advantages: 1) the operation is simple; 2) test contrasts under different electrode conditions are convenient; 3) test contrasts under different flame conditions are convenient; and 4) support can be provided for quantitative research of the trip factors and rules of the transmission line.
Description
Technical field
The invention belongs to the electrical engineering technical field, relate in particular to a kind of transmission line of electricity mountain fire trip test platform.
Background technology
China's southern area forest fire takes place frequently, according to investigations, be mostly to sweep a grave, offer a sacrifice to an ancestor, burn the grass on waste land, burn stalk so these people's lives customs of smoking due to, like arid weather, its evil more very.And transmission line of electricity is crossed over the easy location of sending out of mountain fire usually, in case there is mountain fire to take place, hurts first, and very easily causes the transmission line of electricity tripping operation.Transmission line of electricity is because of after mountain fire trips, because the dirty influence of subproduct of being insulated, real difficulty is closed a floodgate again and recovered to send electricity, even often cause the power failure permanent fault, has a strong impact on the people's ordinary production and life, also national wealth is caused damage.Yet up to the present,, be close to the observation that rests on through mountain fire tripping operation field condition, the position and the character type of mountain fire tripping operation are made judgement for the research of transmission line of electricity mountain fire tripping operation.And for the true cause that causes the transmission line of electricity tripping operation, only aspects such as flame temperature, air insulation level and dust concentration are analyzed in the conjecture qualitatively even also rest on mostly, lack quantitative experimental study result.
Summary of the invention
The technical matters that the present invention will solve is; Backward situation to the anti-control techniques of present mountain fire tripping operation; Design a kind of transmission line of electricity mountain fire trip test platform; Carry out correlation test research through this platform, can obtain between the different condition bottom electrode air breakdown voltage phenomenon, and then analyze and influence factor and the rule that mountain fire causes transmission line of electricity to trip with the relation of different factors vary.
Technical solution of the present invention is, the transmission line of electricity mountain fire trip test platform that is designed, and referring to Fig. 1, it is as shown in Figure 1, is composed in series successively by pressure regulator 1, transformer 2, resistance 3, electrode 4, ground-electrode 5.The input end of the said transformer 2 of output termination of wherein said pressure regulator 1.The output terminal of this transformer 2 is connected to said electrode 4 through resistance 3.Be connected with the line-line electrode form of the clearance that has adjustable gaps or rod-plate electrode form of having the rod-bar electrode form of the clearance of adjustable gaps or having a clearance of adjustable gaps between this electrode 4 and the said ground-electrode 5.
Principle of work of the present invention is: by the input termination power frequency civil power of pressure regulator 1; Promptly obtain working power from the power frequency civil power; Regulate the input end of output voltage to transformer 2; After transformer 2 boosts, transport to electrode 4 make electrode 4 band high pressure and and ground-electrode 5 between form voltage, when this voltage surpassed the tolerance level of the clearance between electrode 4 and the ground-electrode 5, the clearance was promptly breakdown.Electric current when resistance 3 is used for the limit air gap breakdown, one can reduce the ablation of electrode surface, and two can protect transformer 2 to exempt from damage.Below the clearance between electrode 4 and the ground-electrode 5, place the burner of a tape drum blower fan; Be that this burner capable of using is implemented the burning of simulation mountain fire, simulate the size of the mountain fire intensity of a fire in the size control burner of what or the defeated wind-force of fan blower institute through control burner internal combustion thing.Through the distance of the clearance between adjusting electrode 4 and the ground-electrode 5, and the size of regulating the simulation mountain fire intensity of a fire in the burner, the Air Gap Breakdown Voltage value under the different condition can be obtained.Environment temperature, flame temperature, electrode temperature and airion concentration parameter when writing down the puncture of each clearance, using conventional method to analyze influences factor and the rule that mountain fire causes the transmission line of electricity tripping operation.
The invention has the beneficial effects as follows:
1), simple to operate, easy to use;
2), very convenient in the test contrast of carrying out under the different electrode conditions;
3), the interior simulation of the burner mountain fire intensity of a fire can be controlled, thereby be convenient to carry out the test contrast under the different flame conditions;
4), can be the factor that causes transmission line of electricity tripping operation and the quantitative examination of rule provides support.
