Technical field
The present invention relates to a kind of adhesion condition detection method, particularly a kind of 220kV split conductor adhesion condition detection method.
Background technology
Now the 220kV split conductor circuit of operation, because design and technical reason are divided into homeotropic alignment, horizontally and tiltedly arrange three kinds, and does not add conductor spacer between split conductor.Conventionally the cross section of wire is divided into 2*300mm2 and 2*400mm2 etc., and the structure of wire is steel-cored aluminium strand.Along with the high speed development of national economy, the sharply variation of town and country need for electricity, the part circuit of electrical network is born heavy duty load, and especially, in the time that line fault or transformer station's scheduled overhaul or repair based on condition of component appear in electrical network, the structure of electrical network changes, as the 220kV circuit of regional important load carrying, to change normal carrying capacity, and play the task of load adjustment between region, wire is being born the large electric current of large load, the now electromagnetic field great change of wire, mechanical electric performance also changes.Electromagnetic field changes the sound field of bringing greatly and changes, and load increases the tension variation that causes wire, and principal character is that oidiospore wire attractive force increases, and wire sticks together.After conductor adhesion, there is electric field and the sound field of distortion, not only line wire itself is had impact but also can environment around be impacted.
Summary of the invention
According to above deficiency of the prior art, the problem to be solved in the present invention is: provide one to administer parameter is provided for circuit regulate and control operation and adhesion, reduce the 220kV split conductor adhesion condition detection method because of the impact of magnetic field or Noise upon Environment.
The technical solution adopted for the present invention to solve the technical problems is:
Described 220kV split conductor adhesion condition detection method, comprises the following steps:
(1) according to the operating load before and after split conductor adhesion, use the current-carrying of dispatch automated system or scheduling load monitoring system inquiry split conductor, by before and after split conductor adhesion with current parameters judge the adhesion situation of split conductor;
(2) after split conductor adhesion is determined, by infrared thermometer, the three-phase of split conductor is carried out respectively to temperature test, the relatively split conductor phase of adhesion and the temperature of proper splitting wire phase, determine the temperature value exceeding, judge the adhesion state of split conductor, the split conductor of adhesion is compared proper splitting wire and is exceeded mutually 10-20 degree;
(3) detect the noise of the split conductor of adhesion by noise level monitor, judge whether to form noise source, the decibel of noise is greater than 55 decibels and forms noise sources;
(4) detect power frequency electric field and the power frequency magnetic field of split conductor of adhesion by electromagnetism tester, judge whether to exceed safety standard, the standard of power frequency electric field is 4kV/m, and the standard of power frequency magnetic field is 100 μ T.
The power frequency electric field of split conductor of described electromagnetism tester detection adhesion and the position of power frequency magnetic field are within the scope of 15 meters of split conductor adhesion section guard plot.Split conductor adhesion section guard plot is centered by conductor adhesion section, around the distance within the scope of 15 meters.
Described noise level monitor detects the upright position of position split conductor adhesion section within the scope of 15 meters of split conductor adhesion section guard plot or in guard plot of the noise of the split conductor of adhesion.
The beneficial effect that the present invention has is:
1, detection method and means simple, easy to operate, easily grasp, can, in conjunction with dispatch automated system, grasp in real time the load characteristic of adhesion wire.
2,, by data analysis with the measure of solution is provided, make the line security operation of electrical network.
3, can avoid in time bringing thus the environmental protection within the scope of " sensitive spot ", especially residential block and school, implement noise abatement, environmental protection, green environment are provided.
The present invention is according to the corresponding rule and standard of country and operation, detect by the temperature to after the adhesion of 220kV split conductor, noise, magnetic field intensity, electric field intensity, effectively grasp in real time the data of adhesion, by the analysis of data, grasp the impact on its surrounding environment, and take to reduce load or increase the measures such as conductor spacer, reduce because of the caused environmental protection of impact of the electromagnetism after conductor adhesion and noise and complain, ensure the safe operation of circuit.
