Combined protection type mixed triggering power source based on logic protection amplifying circuit

Abstract

The invention discloses a mixed triggering type power source based on a logic protection amplifying circuit. The mixed triggering type power source based on the logic protection amplifying circuit is mainly composed of a transformer diode triggering circuit, a power logic control circuit, a crystal oscillating circuit and a buffering crystal oscillating circuit, wherein the power logic control circuit is connected with the transformer diode triggering circuit, and the crystal oscillating circuit and the buffering crystal oscillating circuit are connected with the transformer diode triggering circuit. The mixed trigger type power source based on the logic protection amplifying circuit is characterized in that a logic protection amplifying circuit is further connected between the transformer diode triggering circuit and the power logic control circuit in series. By the adoption of the mixed triggering type power source based on the logic protection amplifying circuit, a circuit structure is greatly simplified, the radio-frequency interference of the circuit and radio-frequency interface of external connection are reduced, and manufacturing cost and the maintenance cost are greatly reduced; meanwhile, the delay effect of a traditional power circuit can be effectively overcome, and the quality of the power source can be effectively improved.

Description

technical field [0001] The invention relates to a switching stabilized voltage power supply, in particular to a combined protection type hybrid trigger power supply based on a logic protection amplifier circuit. Background technique [0002] At present, with the rapid development of the power industry, the equipment that people use for power system fault detection has also developed greatly. Since the maintenance of the power system often involves voltage lines of hundreds of kilovolts or even millions of kilovolts, the maintenance lines are very long, so the power supply requirements for fault detection equipment are also very high. However, at present, the mobile power supply provided by the fault detection equipment has a large ripple coefficient, which not only produces radio frequency electromagnetic interference, but also has a complicated circuit structure, high maintenance and production costs, which largely limits The scope of use of fault detection equipment is no...
