Description
При емкости С 100 мкф необходима индуктивность L ОД С 10 мкф L , 1 гн. Эти величины дл L. и С вполне приемлемы дл практического осуществлени .When the capacitance is 100 μf, the inductance L ОД С 10 μf L, 1 g is necessary. These values for L. and C are quite acceptable for practical implementation.
Устройство работает следующим образом .The device works as follows.
С помощью прибора контрол изол ции, выполненного в виде системы вентилей, выпр мл ющих , ток в пепи контролирующий прибор - изол ци сети, регистрируетс величина тока, завис ща от общего омического сопротивлени изол ции трех фаз сети. Так как нейтраль с включенным резонансным контуром представл ет больщое сопротивле- ние дл выпр мленных токов, то последние проход т по цепи регистрирующий прибор изол ци сети, и измерение осуществл етс так же , как в сет х с изолированной нейтралью..With the help of an isolation control device made in the form of a system of valves rectifying the current in the pep control device — network insulation, the current is measured depending on the total ohmic resistance of the insulation of the three phases of the network. Since the neutral with the included resonant circuit represents a great resistance for the rectified currents, the latter pass through the circuit of the registering device and isolate the network, and the measurement is performed in the same way as in networks with an isolated neutral.
Таким образом использование известных устройств непрерывного контрол изол ции сетей с изолированной нейтралью в сет с глухозаземленной нейтралью при дополнительном введении в нейтраль трансформатора резонансного контура дает возможность рещить вопрос непрерывного контрол изол ции дл рассматриваемых сетей.Thus, the use of the known devices for continuous monitoring of insulation of networks with insulated neutral in a network with a solidly earthed neutral, with the additional introduction of a resonant circuit into the neutral of the transformer, makes it possible to resolve the issue of continuous monitoring of insulation for the networks in question.
Применение непрерывного контрол изол ции позвол ет судить об уровне изол ции в любой момент времени.The use of continuous insulation monitoring allows you to judge the level of insulation at any time.
Кроме того, поддерж нйе изол ции на высоком уровне снижает веро тность возникновени замыканий на землю и электрооборудование , увеличива тем самым уровень электробезопасности.In addition, maintaining insulation at a high level reduces the likelihood of earth faults and electrical equipment, thereby increasing the level of electrical safety.
