Description

Przedmiotem wynalazku jest miernik natezenia pola elektrycznego przeznaczony do wykonywania pomiarów w warunkach produkcji przemyslowej jak iw warunkach laboratoryjnych. Ponadto miernik ten sluzy do okreslania zródel elektrycznosci statycznej oraz pomiaru wartosci natezenia pola elektrycznego w dowolnym miejscu przestrzeni i równiez w strefach zagrozonych wybuchem lub pozarem.The subject of the invention is an electric field intensity meter to be performed measurements in industrial production conditions as well as in laboratory conditions. In addition, this meter serves for determining the sources of static electricity and measuring the value of electric field strength in any place in space and also in areas endangered by explosion or fire.

Z polskiego opisu patentowego nr 79044, znany jest przyrzad do pomiaru elektryzowania obiektów plaskich. Przyrzad ten sklada sie z elektrometru polaczonego z jednej strony przewodem w plaszczu ekranowym, z pomiarowa sonda umieszczona w ekranie, a z drugiej strc.iy z uziemieniem. Ekran jest polaczony z uziemieniem poprzez kondensator. Naelektryzowany obiekt plaski znajduje sie pomiedzy sonda a uziemieniem.From the Polish patent description No. 79044, an instrument for measuring the electrification of objects is known flat. The apparatus consists of an electrometer connected at one end by a sheathed cable screen, with the measuring probe placed in the screen, and on the other side with ground. The screen is connected to grounding through a capacitor. The electrified flat object is between the probe and the ground.

Opisany przyrzad przystosowany jest tylko do pomiaru obiektów plaskich, nie posiada autonomicznego zasilania i nie moze byc uzywany w strefach zagrozonych wybuchem.The described device is designed only for measuring flat objects, it does not have an autonomous one power supply and must not be used in hazardous areas.

Celem wynalazku jest skonstruowanie miernika umozliwiajacego latwy, prosty i szybki pomiar wartosci natezenia pola elektrycznego w dowolnym miejscu przestrzeni, niezaleznie od ksztaltu elektryzujacego sie ciala, w warunkach produkcji przemyslowej, gdzie istnieje zagrozenie wybuchem i pozarem. Przyrzad jest tak zbudowany, ze glowica wraz z miernikiem tworzy jeden konstrukcyjny przenosny element.The object of the invention is to construct a meter that enables easy, simple and fast measurement of values the intensity of the electric field in any place in space, regardless of the shape of the electrifying body, in conditions of industrial production where there is a risk of explosion and fire. The apparatus is like this built that the head and the meter form one portable construction element.

Miernik wedlug wynalazku zaopatrzony w zródla pradu stalego utworzony jest z glowicy pomiarowej, w której istnieje jedna elektroda drgajaca, pelniaca jednoczesnie role elektrody pomiarowej, generatora, wzmacniacza mocy, wzmacniacza pomiarowego, mostka fazoczulego oraz miernika wychylowego.The meter according to the invention provided with a direct current source consists of a measuring head, i where there is one vibrating electrode, which at the same time acts as a measuring electrode, generator, a power amplifier, a measuring amplifier, a phase-sensitive bridge and a tilt meter.

Przedmiot wynalazku uwidoczniony jest w przykladowym wykonaniu na rysunku przedstawiajacym elektryczny schemat blokowy ukladu.The subject of the invention is illustrated in an exemplary embodiment in the illustrating drawing electrical block diagram of the system.

Miernik sklada sie z glowicy 1 pomiarowej, która polaczona jest z jednej strony z generatorem 2 pomiarowym poprzez wzmacniacz 3 mocy, a z drugiej strony ze wzmacniaczem 4 pomiarowym, mostkiem 5 fazoczulytn, który jest równiez polaczony z generatorem 2. Mostek 5 fazoczuly polaczony jest z miernikiem 6.The meter consists of the measuring head 1, which is connected on one side to the generator 2 through the 3 power amplifier, and on the other side with the 4 measuring amplifier, bridge 5 Phasensitive, which is also connected to generator 2. The 5-phase sensitive bridge is connected to the meter 6.

W glowicy 1 obudowanej w ekran 9 znajduje sie elektroda 7 pomiarowa polaczona bezposrednio ze wzmacniaczem 4 oraz cewka 8 uruchamiajaca elektrode 7 polaczona bezposrednio ze wzmacniaczem 3 mocy.2 102 408 Dzialanie miernika polega na tym, ze badanego punktu zbliza sie miernik, wskutek czego drgajaca elektroda 7 pomiarowa uzyskuje potencjal zalezny od wielkosci natezenia pola w badanym punkcie. Wytworzone napiecie pomiedzy elektroda 7 a ekranem 9 po wzmocnieniu poprzez wzmacniacz 4 i porównaniu znaku z napieciem wytworzonym przez generator 2 w mostku 5 fazoczulym, mierzone jest -ia skali miernika 6 wychylowego. _^|jwja p0mjar w dowolnym punkcie przestrzeni.In the head 1 enclosed in a screen 9 there is a measuring electrode 7 connected directly to it amplifier 4 and coil 8 actuating electrode 7 connected directly to the amplifier 3 power 2 102 408 The meter works by bringing the test point closer to the meter, making it vibrate the measuring electrode obtains a potential that depends on the magnitude of the field intensity at the examined point. Produced the voltage between electrode 7 and shield 9 after amplification by amplifier 4 and comparing the sign with voltage generated by generator 2 in the phase-sensitive bridge 5, is measured on the scale of the meter 6 tilt. _ ^ | jwja p0mjar at any point in space.
