Abstract

Электрический трансформатор 1 содержит бак 4, внутри которого находится жидкий или газообразный диэлектрик 5, в который погружены первичная цепь и вторичная цепь и защитное устройство, подключенное к первичной цепи, и содержащее автоматический выключатель 15, управляемый размыкающим средством, и один или несколько плавких предохранителей 11. Плавкие предохранители расположены между вводом 7 бака и автоматическим выключателем 15. Плавкие предохранители 11, автоматический выключатель 15 и размыкающее средство соединены таким образом, что при условиях, соответствующих короткому замыканию, на зажимах вторичной цепи контактные средства автоматического выключателя осуществляют разделение и прерывают ток без начала плавления плавкого предохранителя и что существует пороговая величина силы тока, протекающего в плавком предохранителе, ниже мощности разрыва соответствующего полюса автоматического выключателя и выше которой имеет место плавление плавкого предохранителя перед тем, как оказалась способной вызвать разделение контактов разделяющая команда, данная контактным средствам размыкающим средством.The electric transformer 1 contains a tank 4, inside of which there is a liquid or gaseous dielectric 5, in which the primary circuit and the secondary circuit and the protective device connected to the primary circuit are immersed, and contains a circuit breaker 15 controlled by the disconnecting means and one or more fuses 11 The fuses are located between the tank inlet 7 and the circuit breaker 15. The fuses 11, the circuit breaker 15 and the disconnecting means are connected in such a way that when in the secondary circuit terminals, the contact means of the circuit breaker separate and interrupt the current without melting the fuse and that there is a threshold value of the current flowing in the fuse below the breaking capacity of the corresponding pole of the circuit breaker and above which melting takes place fuse before being able to cause a separation of the contacts the dividing command given by the contact stvam NC tool.
