Description

жит параллельно-последовательно соединенные герконы 1, включенные а цепь управл ющих электродов тиристоров, основную, обмотку 2 возбуждени , отделенную от герконов слоем высоковольной изол ции и подключенную передающим кабелем 3 к блоку отпирани  тиристоров, и дополнительную обмотку 4 возбуждени , размещенную на общем каркасе с первой обмоткой, а также герконовое реле 5, расположенное в зоне магнитного вли ни  обмоток 2 и Л возбуждени . Герконовое реле установлено в поле посто нного магнита 6.the parallel-connected reed switches 1, connected to the thyristor control electrode circuit, the main excitation winding 2, separated from the reed switches by a layer of high-voltage insulation and connected by a transmitting cable 3 to the thyristor unlocking unit, and an additional excitation winding 4 placed on a common frame with the first winding, as well as the reed relay 5, located in the zone of magnetic influence of the windings 2 and L excitation. The reed switch is installed in the permanent magnet 6 field.

Обмотка герконового реле 5 включена таким образом, что создаваемое ею магнитное поле направлено встречно полю обмоток.возбуждени  и совпадает с полем посто нного магнита 6. Реле 5 установлено на таком расто нии от обмоток 2 и 4 возбуждени , что результирующее магнитное поле, образованное обмоткой возбуждени  2 (или )и обмоткой ре е 5, равно 0. А посто нный магнит 6 установлен на таком рассто нии от реле 5, что создаваемое им поле не Вызывает срабатывание геркона реле 5Таким образом, в нормальных режимах геркона реле 5 находитс  под действием слабого магнитного пол  посто нного магнита 6, не вызывающего его срабатывани .The winding of the reed switch 5 is turned on in such a way that the magnetic field created by it is directed opposite to the field of the excitation windings and coincides with the field of the permanent magnet 6. Relay 5 is installed at such a distance from the excitation windings 2 and 4 that the resulting magnetic field formed by the excitation winding 2 (or) and winding re e 5 is equal to 0. And the permanent magnet 6 is set at such a distance from the relay 5 that the field created by it does not cause the reed switch to activate the relay 5. Thus, in normal modes of the reed switch the relay 5 is affected by a weak magnetic field of the permanent magnet 6, without causing it to operate.

Устройство работает следующим образом .The device works as follows.

При подаче питани  по передающему кабелю 3 электрический ток протекает по основной обмотке 2 возбуждени  и по обмотке герконового реле 5.Магнитное поле обмотки реле 1 компенсируетс  полем основной обмотки 2 возбуждени , поэтому переключение геркона реле 5 не происходит. В случае перегорани  основной обмотки 2 возбуждени  исчезает ее размагничивающее магнитное поле и геркон реле 5 срабатывает под действием пол  собственной обмотки, переключа  передающий кабель 3 с основной обмотки 2 на дополнительную обмотку 4. После срабатывани  геркона реле 5 слабое магнит ное поле посто нного магнита 6 удерживает геркон в таком состо нии, несмотр  на по вление магнитного пол  дополнительной обмотки 4 возбуждени . Геркон удерживаетс  в таком состо нии посто нно, независимо от наличи  или отсутстви  входного сигнала .. Вли ние посто нного магнита 6 объ сн етс  очень низким коэффициентом возврата герконовых реле.When power is supplied via the transmitting cable 3, the electric current flows through the main excitation winding 2 and the winding of the reed switch 5. The magnetic winding field of the relay 1 is compensated by the main excitation winding 2, therefore switching the reed switch of the relay 5 does not occur. If the main winding 2 of the excitation fails, its demagnetizing magnetic field disappears and the reed switch of the relay 5 operates under the action of its own winding field, switching the transfer cable 3 from the main winding 2 to the additional winding 4. After the relay 5 of the relay actuates, the weak magnetic field of the permanent magnet 6 the reed switch is in such a state, despite the appearance of the magnetic field of the additional excitation winding 4. The reed switch is held in this state continuously, regardless of the presence or absence of an input signal. The effect of the permanent magnet 6 is explained by a very low return coefficient of the reed switch.

Таким образом, при одновременности наличи  напр жени  на передающем кабеле 3 и магнитного пол  основной обмотки возбуждени  срабатывание геркона реле 5 не происходит, а при исчезнове.нии магнитного пол  основной обмотки возбуждени  и наличии напр жени  на передающем кабеле 3 происходит переключение на дополнительную обмотку возбуждени . При перегорании обмотки реле 5 срабатывание геркона не происходит, так как поле обмотки возбуждени  и поле посто нного магнита 6 ослабл ют друг друга.Thus, with the simultaneous presence of voltage on the transmitting cable 3 and the magnetic field of the main excitation winding, the reed switch 5 does not operate, and when the magnetic field of the main excitation winding disappears and the voltage on the transmitting cable 3 is switched to an additional excitation winding. When the relay coil 5 burns out, the reed switch does not trigger, since the field of the excitation winding and the field of the permanent magnet 6 weaken each other.

Предлагаемое устройство обладает большей надежностью по сравнению с известным.The proposed device has greater reliability compared with the known.
