Abstract

Pomocou prístroja sa nasimuluje vadný stav rozvodnej slete a elektronickými stopkami sa sleduje doba reakcie kontrolovaného strážiča.The device simulates a faulty state of the distribution board and an electronic stopwatch monitors the reaction time of the monitored guard.

Description

Vynález sa týká zapojenia pre kontrolu strážičov izolačného stavu, menovite zostavy a zapojenia jeho jednotlivých častí do funkčného celku. V elektrických rozvodových sietach sa používajú zariadenia, ktoré nepřetržíte kontrolujú izolačný stav rozvodovej siete známe pod názvom strážiče izolačného stavu. Pri poklese izolačného stavu pod nastavenu — normou stanovenu hodnotu dávajú povel na signalizáciu zníženia izolačného stavu a pri ďalšom znížení na nebezpečnu hodnotu dávajú povel na odpojenie vadného úseku rozvodovej siete. Pre kontrolu správnej funkcie sú sice tieto zariadenia opatřené kontrolným tlačidlom, ktorým je možné overiť, či v obvodoch strážiča izolačného stavu nie je porucha, no nedá sa identifikovať či sú správné nastavené hodnoty pre znížený a kritický izolačný stav siete.BACKGROUND OF THE INVENTION The invention relates to a circuit for controlling an insulating state guard, namely an assembly and connecting its individual parts to a functional unit. In power distribution networks, devices are used that continuously check the isolation state of the distribution network known as the isolator. When the insulating state drops below the set value, they give a signal to indicate a reduction in the isolation state and, when further reduced to a dangerous value, command to disconnect the defective section of the distribution network. While checking the correct function, these devices are provided with a check button to verify that there is no fault in the isolator circuits, but it is not possible to identify whether the set values for the reduced and critical isolation status are correct.

Podstata zapojenia pre kontrolu strážičov izolačného stavu spočívá v tom, že strážičom izolačného stavu sledovaná elektrická sieť je připojená cez sériovo zapojený obvod pozostávajúci z prepínača fáz poistky, štartovacieho spínača a kontrolného miliampérmetra, na zemniacu sústavu. Startovacím spínačom zapnutý obvod je zároveň spriahnutý s elektronickými stopkami pripo- jenými na napájacie napatie a obsahujúcimi kontakt strážiča izolačného stavu a nulovacie tlačidlo.The essence of the circuitry for controlling the isolators is that the mains power monitor monitored by the isolator is connected via a series-connected circuit consisting of a fuse phase switch, a starter switch and a milliameter, to the grounding system. The on / off switch is also coupled to the electronic stopwatch connected to the supply voltage and containing the isolator contact and reset button.

Zariadenie na kontrolu strážičov izolačného stavu rieši možnosť preskúšania a nastavenia zníženej a kritickej hodnoty izolačného stavu siete simulováním tohto stavu pomocou regulačného odporu. Pri nastavení zníženej, resp. kritickej hodnoty a připnutí zariadenia na kontrolnú sieť sa zároveň meria chybný prúd siete a elektronickými stopkami sa odmeria doba vybavenia kontrolovaného strážiča izolácie.The device for checking the isolators has the possibility of checking and adjusting the reduced and critical value of the isolation state of the network by simulating this state by means of a control resistance. When set to low or low. Critical value and pinning the device to the control network are simultaneously measuring the faulty mains current and the electronic stopwatch measures the equipment time of the controlled insulation guard.

Zapojenie prístroja na kontrolu strážičov izolačného stavu je riešené sériovým obvodom, ktorý pozostáva podfa obrázku z prepínača fáz 3, poistky 4, štartovacieho spínača 5, nastavovacieho odporu 6 a kontrolného miliampérmetra 7 a je připojený na zemiacu sústavu 8 siete 1. Ďalší kontakt štartovacieho spínača 5 je zapojený v obvode napájania elektronických stopiek 12, připojených na napájacie napatie cez svorky 9 a počítanie reakčného času kontrolovaného strážiča je ukončené kontaktom 10 strážiča izolačného stavu, zapojeného do obvodu stopiek. Nulový stav stopiek sa nastaví připojeným nulovacím tlačidlom 11.The connection of the device for checking the insulating state guard is solved by a serial circuit which consists, according to the figure, of a phase switch 3, a fuse 4, a start switch 5, an adjusting resistor 6 and a milliameter 7 and is connected to the network ground system 8. it is connected in the power supply circuit of the electronic stems 12 connected to the supply voltage via the terminals 9 and the counting of the reaction time of the controlled guard is terminated by the contact 10 of the isolator guard connected to the stalk circuit. The stopwatch zero is set with the connected reset button 11.
