Description
technical field [0001] The invention relates to a delay intermediate relay circuit, in particular to a static adjustable delay intermediate relay circuit. Background technique [0002] Time-delay intermediate relays are used in various protection and automatic control circuits operated by DC or AC. As an auxiliary relay to increase the number of contacts and contact capacity. The time of power-on delay or power-off delay can be adjusted as required. [0003] With the advancement of science and technology, various new types of electrical equipment have sprung up like mushrooms after rain. These new electrical equipment often need to be connected to different power supply systems. There are large voltage fluctuations in various power supply systems, and large voltage fluctuations are likely to cause the usual delay intermediate relays to malfunction. Contents of the invention [0004] In order to solve the technical problem that the common time-delay intermediate relay i...
