Abstract
The invention discloses a method applied to the measurement of power frequency electric field intensity in a high-humidity environment. The method comprises the following steps of: (1) arranging an additional dehumidification device, and connecting the dehumidification device and a conventional power frequency electric field intensity measurement apparatus by using a hose; (2) providing a drying wind source; (3) sealing a probe of the power frequency electric field intensity measurement apparatus by blowing drying wind to the probe of the power frequency electric field intensity measurement apparatus; and (4) starting the power frequency electric field intensity measurement apparatus to perform the measurement of the power frequency electric field intensity in the high-humidity environment. The additional dehumidification device arranged in the method is matched with a plurality of other apparatuses working in the high-humidity environment, thereby making the apparatuses free from the limitations of environmental factors and work normally and ensuring the accuracy of a measured power frequency electric field intensity value in the high-humidity environment; and the method is less in investment, convenient to operate and high in accuracy.
Description
Technical field
The invention belongs to field of environment engineering technology, be specifically related to a kind of method of measuring power-frequency electric field strength under the high humidity environment that is applicable to.
Background technology
Along with the propelling simultaneously and rapidly of power grid construction and urban construction, the improving constantly of living standards of the people and environmental consciousness, people are increasing to the concern of electric field intensity around the ultra-high-tension power transmission line.Thereby existing AC power frequency electric field intensity measuremenrt instrument is to calculate the relative electric fields intensity level by the induction current of measuring between capacitance sheet.And under the high humidity environment, the surveying instrument surface forms and easily forms great leakage current between moisture film and capacitance sheet pole plate, thereby make the induced electricity flow valuve that records be full of false composition and insincere, and then make the power-frequency electric field strength value that records under the high humidity environment higher greatly.Because the singularity that power-frequency electric field strength is measured can not have any screen between field source and surveying instrument probe, so existing surveying instrument can't accurately be measured power-frequency electric field strength under high humidity.
Summary of the invention
The technical problem to be solved in the present invention is, the defective that exists when working under high humidity environment at known surveying instrument provides a kind of method of measuring power-frequency electric field strength under the high humidity environment that is applicable to, this method not only should be able to be guaranteed the authenticity of data-signal, and invest and will lack, take effect and want fast.
Technical solution of the present invention is, what provided a kind ofly is applicable to that the method for measuring power-frequency electric field strength under the high humidity environment is to be following step:
(1), sets up dehydrating unit.The dehydrating unit of setting up a band blower fan for existing power-frequency electric field strength surveying instrument, this dehydrating unit air outlet is connected by flexible pipe with this power-frequency electric field strength surveying instrument probe;
(2), provide dry wind regime.The dehydrating unit that setting up procedure (1) is set up, the dry wind that at a distance this dehydrating unit is started the back output by flexible pipe is delivered to around the probe of above-mentioned power-frequency electric field strength surveying instrument, and the air supplying distance scope is 2～5 meters;
(3), wind regime sealing probe.The probe that utilizes step (2) dry wind that obtains to blow to above-mentioned power-frequency electric field strength surveying instrument seals described probe, keep this probe damp atmosphere layer outside to isolate, make described existing power-frequency electric field strength surveying instrument not be subjected to the influence of damp atmosphere layer with it;
(4), implement ionization meter.The existing power-frequency electric field strength surveying instrument that setting up procedure (1) provides, the power-frequency electric field strength that can use this power-frequency electric field strength surveying instrument to implement under the high humidity environment is measured.
Technological core of the present invention is to adopt the dehydrating unit of setting up to produce dry wind, utilize this dry wind to separate contacting of existing power-frequency electric field strength surveying instrument and soft air, make unlikely this power-frequency electric field strength surveying instrument that influences of damp atmosphere layer, avoided simultaneously the foreign body that may make electric field distortion again effectively, thereby assurance is provided for the power-frequency electric field strength measured value that obtains under the high humidity environment accurately.
The invention has the beneficial effects as follows:
1, can guarantee the accuracy of power-frequency electric field strength measured value under the high humidity environment;
2, only in traditional power-frequency electric field strength measuring method, set up the dehydrating unit of a band blower fan, small investment, easy to operate, the efficient height;
3, the dehydrating unit set up of this method mates the Other Instruments of work under the multiple high humidity environment, thereby can make these instruments not be subjected to the restriction of environmental factor and can work as usual.
